Warnings and cautions

Follow the warnings and cautions given below when handling this instrument.
This information is to be supplemented by the warnings and cautions given in

each chapter.

• After using this instrument, reprocess and store it according

Indicates additional helpful information.

to the instructions given in the endoscope’s companion

reprocessing manual whose cover lists the model of your

endoscope. Using improperly or incompletely reprocessed or

stored instruments may cause patient cross-contamination
and/or infection.

• Before endoscopy, remove any metallic objects (watch,

glasses, necklace, etc.) from the patient. If performing

high-frequency cauterization becomes necessary while the
patient wears a metallic object, it may cause burns on the

patient in areas around the metallic object.

• Do not strike, bend, hit, pull, twist, or drop the endoscope’s

distal end, insertion tube, bending section, control section,
universal cord, or endoscope connector of the endoscope

with excessive force. The endoscope may be damaged and

could cause patient injury, burns, bleeding and/or

perforations. It could also cause parts of the endoscope to

fall off inside the patient.

• When performing transnasal insertion of the GIF-N180,

please follow the cautions below.

− The shape and size of the nasal cavity and its suitability
for transnasal insertion may vary from patient to patient.

No endoscope, including this one, can always be inserted

transnasally with all patients. Before proceeding, always

be sure to confirm that transnasal insertion is possible

with the patient. Otherwise, operator and/or patient injury

can result, or the endoscope could become lodged and be
difficult to withdraw.

6

EVIS EXERA II GIF/CF/PCF TYPE 180 Series OPERATION MANUAL

Important Information — Please Read Before Use

− Transnasal insertion is accompanied by the risk of

inflammation of the nasal cavity. If this happens, the nasal

passage will be constricted, making it more difficult to

withdraw the endoscope. In this case, do not use force to
withdraw the endoscope because patient injury such as

bleeding or perforation may result.

− Transnasal insertion is accompanied by the risk of

bleeding in the nasal cavity. Be sure to be prepared to

deal with any bleeding. When withdrawing the

endoscope, observe the inside of the nasal cavity to
ensure that there is no bleeding. Even when the

endoscope has been withdrawn without bleeding, do not

allow the patient to blow his or her nose strongly because

this could cause it to start bleeding.

− Before transnasal insertion, apply the appropriate

pretreatment and lubrication to the patient to enlarge the

nasal cavity. Otherwise, operator and/or patient injury can
result or the endoscope could become lodged and be

difficult to withdraw. When applying a pretreatment agent

through a tube, insert the tube into the same path as the

path planned for the endoscope insertion. Otherwise, the

treatment will have no effect. The effects of the

pretreatment agent and lubricant will decrease the longer
the procedure lasts. Apply the pretreatment agent or

lubricant as required during the procedure

when withdrawal seems to be difficult.

– for example,

− Transnasal insertion of the endoscope should be

performed carefully. If resistance to insertion is felt, or the

patient reports pain, stop insertion immediately.
Otherwise, operator and/or patient injury can result or the

endoscope could become lodged and be difficult to

withdraw.

− If it becomes impossible to withdraw the transnasally

inserted endoscope, pull its distal end out of the mouth,

cut the flexible tube using wire cutters, and after ensuring
that the cut section will not injure the body cavity or nasal

cavity of the patient, withdraw the endoscope carefully.

Therefore, always prepare wire cutters in advance.

• Never perform angulation control forcibly or abruptly. Never
forcefully pull, twist or rotate the angulated bending section.

Patient injury, bleeding and/or perforation can result. It may

also become impossible to straighten the bending section

during an examination.

Patient injury, bleeding and/or perforation can result (only

when using the image magnification of the video system
center CV-180).

• Do not touch the light guide of the endoscope connector

immediately after removing it from the light source because it

is extremely hot. Operator or patient burns can result.

• When the endoscopic image does not appear on the monitor,

the CCD may have been damaged. Turn the video system

center OFF immediately. Continued power supply in such a

case will cause the distal end to become hot and could cause
operator and/or patient burns.

• If it is difficult to insert the endoscope, do not forcibly insert

the endoscope; stop the endoscopy. Forcible insertion can

result in patient injury, bleeding and/or perforation.

• When combining the endoscope with a splinting tube, there is

the risk of perforation or bleeding due to entanglement of the

mucous membrane, or of the tube to becoming separated

from the endoscope and remaining in the body. Before use,
be sure to read the instruction manual for the splinting tube to

fully understand its characteristics.

Important Information — Please Read Before Use

Examples of inappropriate handling

Details on clinical endoscopic technique are the responsibility of trained

specialists. Patient safety in endoscopic examinations and endoscopic treatment

can be ensured through appropriate handling by the physician and the medical

facility. Examples of inappropriate handling are described below;

• Over-insufflating the lumen may cause patient pain, injury, bleeding

and/or perforation.

• Applying suction with the distal end in prolonged contact with the

mucosal surface, with higher suction pressure than required or with

prolonged suction time may cause bleeding and/or lesions.

• The endoscope has not been designed for use in retroflexed
observation in parts of the body other than the stomach. Performing

retroflexed observation in a narrow lumen may make it impossible to

straighten and/or withdraw the endoscope. Retroflexed observation in

parts of the body other than the stomach should be performed only

when the usefulness of doing so is determined to be greater than the

risk that is posed to the patient.

• Inserting, withdrawing and using endo-therapy accessories without a

clear endoscopic image may cause patient injury, burns, bleeding

and/or perforation.

• Inserting or withdrawing the endoscope, feeding air, applying suction or

operating the bending section without a clear endoscopic image may

cause patient injury, bleeding and/or perforation.

2.4 Attaching the chain for water-resistant cap (MAJ-1119)

• Do not lift the endoscope by the chain for water-resistant cap.

Otherwise, operator and/or patient injury can result, or the

endoscope and/or water-resistant cap may be damaged

when the fitting comes off the S-cord connector mount or the
chain connector of the GIF-N180.

• Only connect the fitting to the S-cord connector mount or the

chain connector of the GIF-N180. Connecting the fitting to

the suction connector may impair the connection of the

suction tube to the suction connector. It may also cause the
suction tube to become disconnected from the endoscope

and allow patient debris to spray.

• The chain for water-resistant cap and water-resistant cap

itself cannot be ultrasonically cleaned; doing so could
damage them. The water-resistant cap with the chain can

only be ultrasonically cleaned if connected to endoscopes

that are being cleaned in an endoscope reprocessor (such as

OER) with an ultrasonic cleaning phase.

• When attaching the water-resistant cap to the electrical

connector, do not pinch the chain for water-resistant cap

between the electrical connector of the endoscope and the

water-resistant cap. Otherwise, equipment damage may

result.

• The chain for water-resistant cap and water-resistant cap

cannot be ETO gas sterilized; doing so may damage them. If

the water-resistant cap is connected to the endoscope by the

chain, be sure to remove the chain and the water-resistant

cap from the endoscope before ETO gas sterilization.

Perform the following inspections while the bending section is straight.

• If the movement of the UP/DOWN angulation lock,

RIGHT/LEFT angulation lock and their angulation control

knobs are loose and/or not smooth, or the bending section

does not angulate smoothly, the bending mechanism may be
abnormal. In this case, do not use the endoscope because it

may be impossible to straighten the bending section during

an examination (except GIF-N180).

• If the movement of the UP/DOWN angulation lock and its

angulation control knob are loose and/or not smooth, or the
bending section does not angulate smoothly, the bending

3.5 Inspection and connection of ancillary equipment

Inspection of ancillary equipment

• Attach the water container to the specified receptacle on the

trolley or the light source. If the water container is attached

anywhere else, water may drip from the water container’s

water supply tube, and equipment malfunction can result.

• Take care not to spill water from the water container’s

connection adapter when detaching the connection adapter

from the endoscope. Spilled water could splash on the

equipment, and it may cause equipment malfunction.

Prepare and inspect the light source, video system center, video monitor, water

container, suction pump and endo-therapy accessories as described in their

respective instruction manuals.

Connection of the endoscope and ancillary equipment

Firmly connect the suction tube from the suction pump to the

suction connector on the endoscope connector. If the suction
tube is not attached properly, debris may drip from the tube

and can present an infection-control risk, damage and/or

reduce suction capability.

The CV-100 is not compatible with the GIF-N180. If the

GIF-N180 is used with the CV-100, the endoscopic image

may not appear on the video monitor.

The GIF-H180 and CF-H180AL/I can only be connected to

the CV-180.

1. If any ancillary equipment is ON, turn it OFF.

2. Insert the endoscope connector completely into the scope socket (output

socket when using the CLV-U40) of the light source.

3. Connect the water container’s connection adapter to the air supply

connector and water supply connector (see Figure 3.19).

3.6 Inspection of the endoscopic system

Inspection of the endoscopic image

Do not stare directly at the distal end of the endoscope while
the examination light is ON. Otherwise, eye injury may result.

1. Turn the video system center, light source, video monitor ON and inspect

the endoscopic image as described in their respective instruction manuals.

2. Confirm that light is output from the endoscope’s distal end.

3. While observing the palm of your hand, confirm that the endoscopic image

is free from noise, blur, fog or other irregularities.

4. Angulate the endoscope and confirm that the endoscopic image does not

momentarily disappear or displays any other irregularities.

If the object cannot be seen clearly, wipe the objective lens

using a clean lint-free cloth moistened with 70% ethyl or

isopropyl alcohol.

Inspection of remote switch

All remote control switches should be checked to work
normally even when they are not expected for use. The

endoscopic image may freeze or other irregularities may

occur during examination and may cause patient injury,

bleeding and/or perforation.

Depress every remote control switch and confirm that the specified functions

work normally.

Inspection of the air feeding function

Set the airflow regulator on the light source to “High”, as described in the

1.

light source’s instruction manual.

2. Immerse the distal end of the insertion tube in sterile water to a depth of

10 cm and confirm that no air bubbles are emitted when the air/water valve

is not operated.

3. Cover the hole in the air/water valve with your finger and confirm that air

bubbles are continuously emitted from the air/water nozzle.

EVIS EXERA II GIF/CF/PCF TYPE 180 Series OPERATION MANUAL

53

Chapter 3 Preparation and Inspection

4. Uncover the hole in the air/water valve and confirm that no air bubbles are

emitted from the air/water nozzle.

If a stream of air bubbles is emitted from the air/water nozzle

even though the air/water valve is not being operated and the

distal end of the insertion tube is 10 cm or more below the

surface of the sterile water, there may be an irregularity in the
air feeding function. If the endoscope is used while air is

continuously fed, over-insufflation and patient injury may

result. If air bubbles are emitted from the air/water nozzle,

remove and reattach the air/water valve correctly, or replace

it with a new one. If this fails to stop air bubbles from being

emitted, do not use the endoscope, as there may be a

malfunction. Contact Olympus.

When the distal end of the insertion tube is immersed less

than 10 cm below the surface of the sterile water, a small

amount of air bubbles may be emitted from the air/water

nozzle even when the air/water valve is not operated. This

does not indicate a malfunction.

Inspection of the objective lens cleaning function

Use sterile water only. Non-sterile water may cause patient

cross-contamination and/or infection.

• When the air/water valve is depressed for the first time, it

may take a few seconds before water is emitted.

• If the air/water valve returns to its original position slowly

after water feeding, remove the air/water valve and moisten

the seals with sterile water.

• During the inspection, place the distal end of the endoscope

in a beaker or other container so that the floor does not get

wet.

54

1. Keep the air/water valve’s hole covered with your finger and depress the

valve. Observe the endoscopic image and confirm that water flows on the

entire objective lens.

2. Release the air/water valve. Observe the endoscopic image and confirm

that the emission of water stops and that the valve returns smoothly to its
original position.

EVIS EXERA II GIF/CF/PCF TYPE 180 Series OPERATION MANUAL

3. While observing the endoscopic image, feed air after feeding water by

covering the hole in the air/water valve with your finger. Confirm that the

emitted air removes the remaining water from the objective lens and clears

the endoscopic image.

Inspection of the suction function

• If the suction valve does not operate smoothly, detach it and

reattach it, or replace it with a new one. If the endoscope is

used while the suction valve is not working properly, it may

be impossible to stop suction, which could cause patient
injury. If the reattached or replaced suction valve fails to

operate smoothly, the endoscope may be malfunctioning;

stop using it and contact Olympus.

• If the biopsy valve leaks, replace it with a new one. A leaking
biopsy valve can reduce the efficacy of the endoscope’s

suction system, and may leak or spray patient debris or

fluids, posing an infection-control risk.

Chapter 3 Preparation and Inspection

1. Place the container of sterile water and the endoscope on the same height.

For the inspection, adjust the suction pressure to the same level as it will be

during the procedure.

2. Immerse the distal end of the insertion tube in sterile water with the

endoscope’s instrument channel port at the same height as the water level

in the water container. Press the suction valve and confirm that water is

continuously aspirated into the suction bottle of the suction pump.

3. Release the suction valve. Confirm that suction stops and the valve returns

to its original position.

4. Depress the suction valve and aspirate water for one second. Then, release

the suction valve for one second. Repeat this several times and confirm that

no water leaks from the biopsy valve.

5. Remove the distal end of the endoscope from the water. Depress the

suction valve and aspirate air for a few seconds to remove any water from

the instrument channel.

EVIS EXERA II GIF/CF/PCF TYPE 180 Series OPERATION MANUAL

55

Chapter 3 Preparation and Inspection

Inspection of the instrument channel

1. Insert the endo-therapy accessory through the biopsy valve. Confirm that

the endo-therapy accessory extends smoothly from the distal end. Also

make sure that no foreign objects come out of the distal end.

2. Confirm that the endo-therapy accessory is withdrawn smoothly from the

biopsy valve.

Inspection of the auxiliary water feeding function (for endoscopes with auxiliary water feeding only)

Keep your eyes away from the distal end when inserting

endo-therapy accessories. Extending the endo-therapy

accessory from the distal end could cause eye injury.

• Use sterile water only. Non-sterile water may cause patient

cross-contamination and/or infection.

• Note that the luer port on the MAJ-855 includes a one-way

valve to prevent backflow – do not use the MAJ-855 without

the luer port in place, otherwise backflow of contaminated

material may occur and equipment damage or patient injury

may result.

1. Attach a syringe containing sterile water or the water tube from a water

pump to the luer port of the auxiliary water tube (see Figure 3.23). Feed

water and confirm that water is emitted from the auxiliary water channel at

the distal end of the insertion tube.

2. Make sure that no water leaks from the connection between the connecting

end of the auxiliary water tube and the auxiliary water inlet.

3. Make sure that no water leaks form the connection between the luer port of

the auxiliary water tube and the syringe or water tube.

4. Disconnect the water tube from the water pump or the syringe from the luer

port of the auxiliary water tube. Make sure that no water leaks from the luer

port of the auxiliary water tube and/or the distal end of the insertion tube.

56

EVIS EXERA II GIF/CF/PCF TYPE 180 Series OPERATION MANUAL

Chapter 3 Preparation and Inspection

If the auxiliary water channel is used for feeding water, never

disconnect the auxiliary water tube during an examination;

leave it attached until the endoscope is precleaned. If the

auxiliary water tube is detached before precleaning, water

remaining in the auxiliary water channel may be spilled on

the surrounding equipment. This could cause damage to
and/or malfunction of the equipment.

Chapter 4 Operation

Chapter 4 Operation

The operator of this instrument must be a physician or medical personnel under

the supervision of a physician and must have received sufficient training in

clinical endoscopic technique. This manual, therefore, does not explain or

discuss clinical endoscopic procedures. It only describes basic operation and

precautions related to the operation of this instrument.

• Wear personal protective equipment to guard against
dangerous chemicals and potentially infectious material

during the procedure. Wear appropriate personal protective

equipment, such as eye wear, face mask, moisture-resistant

clothing and chemical-resistant gloves that fit properly and

are long enough so that your skin is not exposed.

• The temperature of the distal end of the endoscope may

exceed 41°C (106°F) and reach 50°C (122°F) due to intense

endoscopic illumination. Surface temperatures over 41°C

(106°F) may cause mucosal burns. Always use the minimum

level of illumination, minimum time and suitable distance
necessary for adequate viewing. Whenever possible, avoid

close stationary viewing and do not leave the distal end of the

endoscope close to the mucous membrane for a long time.

• Whenever possible, do not leave the endoscope illuminated
before and/or after an examination. Continued illumination

will cause the distal end of the endoscope to become hot and

could cause operator and/or patient burns.

• Turn the video system center ON to operate the light
source’s automatic brightness function. When the video

system center is OFF, it cannot operate the light source’s

automatic brightness function, and the light intensity is set to

the maximum level. In this case, the distal end of the

endoscope can become hot and could cause operator and/or

patient burns (when using a light source other than
CLV-180).

58

EVIS EXERA II GIF/CF/PCF TYPE 180 Series OPERATION MANUAL

Chapter 4 Operation

• Never insert or withdraw the endoscope under any of the

following conditions. Otherwise, patient injury, bleeding
and/or perforation can result.

− While the endo-therapy accessory extends from the distal

end of the endoscope.

− While the bending section is locked in position.

− Insertion or withdrawal with excessive force, or forcible

insert or withdrawal.

− While the image is magnified (when using the image

magnification function of the video system center

CV-180).

• Transnasal insertion is accompanied by the risk of

inflammation of the nasal cavity. If this happens, the nasal

passage will be constricted, making it more difficult to

withdraw the endoscope. In this case, do not use force to

withdraw the endoscope because patient injury such as

bleeding or perforation may result.

• Transnasal insertion is accompanied by the risk of bleeding

in the nasal cavity. Be sure to be prepared to deal with any

bleeding. When withdrawing the endoscope, observe the

inside of the nasal cavity to ensure that there is no bleeding.
Even when the endoscope has been withdrawn without

bleeding, do not allow the patient to blow his or her nose

strongly because this could cause it to start bleeding.

• Before transnasal insertion, apply the appropriate

pretreatment and lubrication to the patient to enlarge the

nasal cavity. Otherwise, operator and/or patient injury can

result or the endoscope could become lodged and be difficult

to withdraw. When applying a pretreatment agent through a

tube, insert the tube into the same path as the path planned

for the endoscope insertion. Otherwise, the treatment will
have no effect. The effects of the pretreatment agent and

lubricant will decrease the longer the procedure lasts. Apply

the pretreatment agent or lubricant as required during the

procedure

difficult.

• If any of the following phenomena occur during an

examination, immediately stop the examination and withdraw

the endoscope from the patient as described in Section 5.2,

“Withdrawal of the endoscope with an abnormality” on

page 83.

– for example, when withdrawal seems to be

EVIS EXERA II GIF/CF/PCF TYPE 180 Series OPERATION MANUAL

59

Chapter 4 Operation

− If any abnormality is suspected with the functionality of

the endoscope.

− If the endoscopic image on the video monitor disappears

or freezes unexpectedly.

− If the angulation control knob is locked.

− If the angulation control mechanism is not functioning

properly.

− If the zoom malfunctions (when using the image

magnification function of the video system center

CV-180).

− If the flexibility adjustment ring becomes jammed (for

endoscopes with flexibility adjustment only).

Continued use of the endoscope under these conditions

could result in patient injury, bleeding and/or perforation.

• If an abnormal endoscopic image or function is observed, but

quickly corrects itself, the endoscope may have

malfunctioned. Continuous use of such an endoscope may

cause the abnormality to occur again, at which time it may

not return to the normal condition. In this case, stop the
examination immediately and slowly withdraw the endoscope

while viewing the endoscopic image. Otherwise, patient

injury, bleeding and/or perforation can result.

• Never perform flexibility adjustment while the endo-therapy
accessory extends from the distal end of the endoscope.

Patient injury, bleeding and/or perforation can result (for

endoscopes with flexibility adjustment only).

• Regardless of the flexibility of the endoscope’s insertion tube,
it can cause patient injury, bleeding and/or perforation if it is

forcibly inserted, withdrawn and/or twisted with excessive

force. It is generally believed that an endoscope with a

more-rigid insertion tube is easier to manipulate in the

intestines if used properly. However, it should be noted that

such an endoscope, if used improperly, is more likely to
cause patient pain, injury, bleeding and/or perforation than

an endoscope with a more flexible insertion tube

(for endoscopes with flexibility adjustment only).

60

EVIS EXERA II GIF/CF/PCF TYPE 180 Series OPERATION MANUAL

Chapter 4 Operation

• The flexibility of the insertion tube of the CF-Q180AL/I and

CF-H180AL/I can be adjusted to less than, equal to or more
than that of the CF-Q160L/I. The range of the flexibility

adjustment of the CF-Q180AL/I and CF-H180AL/I are equal

to that of the CF-Q160AL/I.

The flexibility of the insertion tube of the PCF-Q180AL/I can

be adjusted to less than, equal to or more than that of the

PCF-140L/I. The range of the flexibility adjustment of the
PCF-Q180AL/I is equal to that of the PCF-160AL/I.

The insertion tube of the endoscope should be adjusted to

the appropriate flexibility for each case. Always confirm the

flexibility of the insertion tube by holding the insertion tube

with two hands before inserting it into the patient, and adjust

the flexibility as necessary according to the case, region and
patient’s condition during an examination. If you are unsure

of the appropriate flexibility of the insertion tube, set it to the

most-flexible condition. Continuing the examination while the

insertion tube is set to an inappropriate degree of flexibility

may cause patient pain, injury, bleeding and/or perforation

(for endoscopes with flexibility adjustment only).

Set the brightness of the light source to the minimum level
necessary to perform the procedure safely. If the endoscope

is used for a prolonged period at or near maximum light

intensity, vapor may be observed in the endoscopic image.

This is caused by the evaporation of organic material (blood,

moisture in stool, etc.) due to heat generated by the light

guide near the light guide lens. If this vapor continues to
interfere with the examination, remove the endoscope, wipe

the distal end with a lint-free cloth moistened with 70% ethyl

or isopropyl alcohol, reinsert the endoscope and continue the

examination.

4.1 Insertion

Holding and manipulating the endoscope

The control section of the endoscope is designed to be held in the left hand. The
air/water and suction valves can be operated using the left index finger. The

UP/DOWN angulation control knob can be operated using the left thumb. The

right hand is free to manipulate the insertion tube and the RIGHT/LEFT

angulation control knob (see Figure 4.1, the GIF-N180 has only the UP/DOWN

angulation control knob).

Figure 4.1

Insertion of the endoscope

• The shape and size of the nasal cavity and its suitability for

transnasal insertion may vary from patient to patient. No

endoscope, including this one, can always be inserted

transnasally with all patients. Before proceeding, always be

sure to confirm that transnasal insertion is possible with the

patient. Otherwise, operator and/or patient injury can result,
or the endoscope could become lodged and be difficult to

withdraw.

• Transnasal insertion of the endoscope should be performed

carefully. If resistance to insertion is felt, or the patient
reports pain, stop insertion immediately. Otherwise, operator

and/or patient injury can result or the endoscope could

become lodged and be difficult to withdraw.

62

EVIS EXERA II GIF/CF/PCF TYPE 180 Series OPERATION MANUAL

Chapter 4 Operation

• To prevent the patient from accidentally biting the insertion

tube during an examination, it is strongly recommended that

a mouthpiece be placed in the patient’s mouth before

inserting the endoscope (for GIF models only).

• To prevent the patient from accidentally loosing dental

prosthesis, make sure that the patient removes them before

the examination.

• Do not apply olive oil or products containing petroleum-based

lubricants (e.g. vaseline). These products may cause

stretching and deterioration of the bending section’s

covering.

• Do not allow the insertion tube to be bent within a distance of

10 cm or less from the junction of the boot. Insertion tube

damage can occur (see Figures 4.2 and 4.3).

3. Insert the distal end of the endoscope through the opening of the

mouthpiece, then from the mouth to the pharynx, while viewing the

endoscopic image. Do not insert the insertion tube into the mouth beyond

the insertion tube limit mark.

 For CF/PCF models

To determine the correct splinting tube to use with the

endoscope, select one of the combinations shown in the

“Accessories (for CF/PCF models only)” table in the

“Appendix” on page 91.

1. If necessary, apply a medical-grade, water-soluble lubricant to the insertion

tube.

2. Insert the insertion tube of the endoscope into the splinting tube if required,

and apply lubricant to the splinting tube.

3. Always view the endoscopic image when passing the distal end of the

endoscope from the anus to the rectum. Do not insert the insertion tube into
the anus beyond the insertion tube limit mark.

Angulation of the distal end

Avoid forcible or excessive angulation, as this imposes load

on the wire controlling the bending section. This may cause

stretching or tearing of the wire, which could impair the

movement of the bending section.

1. Operate the angulation control knobs as necessary to guide the distal end

for insertion and observation.

2. The endoscope’s angulation locks are used to hold the angulated distal end

in position.

64

EVIS EXERA II GIF/CF/PCF TYPE 180 Series OPERATION MANUAL

• When passing an endo-therapy accessory through the

instrument channel while the angulation is locked, the angle

of the distal end may change. When it is necessary to keep

the angulation stationary, hold the angulation control knob(s)
in place with your hand.

• When operating the UP/DOWN or RIGHT/LEFT angulation

lock, hold the angulation control knob stationary with your

finger. If this is not done, the angulation will change (the
GIF-N180 has only the UP/DOWN angulation control knob).

Flexibility adjustment (for endoscopes with flexibility adjustment only)

• Do not change the insertion tube’s flexibility abruptly.

Otherwise, patient pain, injury, bleeding and/or perforation
can result.

Chapter 4 Operation

• If the endoscopic image moves suddenly or is lost, while you

are changing the insertion tube’s flexibility, stop changing the

flexibility and restore the optimal field of view. Moving the
flexibility adjustment ring without a clear endoscopic image

may cause patient pain, injury, bleeding and/or perforation.

• If the patient complains of pain, while you are changing the

insertion tube’s flexibility, stop changing the flexibility and
ensure the safety of the patient.

• If the rigidity of the insertion tube has to be increased during

an examination, confirm that there are no loops or excessive

bends in the insertion tube (using fluoroscopy, if necessary)
before increasing its rigidity. If the force required to turn the

flexibility adjustment ring is greater during the procedure than

it was when inspecting the endoscope, it may mean that the

insertion tube is excessively bent inside the patient. In this

case, straighten the insertion tube as much as possible

before attempting to increase the rigidity. Failure to do so
may cause patient pain, injury, bleeding and/or perforation.

EVIS EXERA II GIF/CF/PCF TYPE 180 Series OPERATION MANUAL

2. When changing the insertion tube’s flexibility during a procedure, turn the

flexibility adjustment ring slowly, and closely monitor the position of the

flexibility marks, the endoscopic image and the patient’s condition.

Whenever the endoscope is not in use, set the insertion tube

to its most-flexible condition. Otherwise, endoscope damage

may result.

Air/water feeding and suction

• If the sterile water level in the water container is too low, then

air, not water, will be supplied. In this case, turn the airflow

regulator on the light source OFF and add sterile water to the

water container until it reaches the specified water level.

Flexible

66

• If air/water feeding does not stop, turn the airflow regulator

on the light source OFF and replace the air/water valve with a

new one.

• Before using a syringe to inject liquid through the biopsy

valve, detach the valve’s cap from the main body. Then insert

the syringe straight into the valve and inject the liquid. If the

cap is not detached and/or the syringe is not inserted

straight, the biopsy valve could be damaged, which could
reduce the efficacy of the endoscope’s suction system, and

may leak or spray patient debris or fluids, posing an

infection-control risk.

EVIS EXERA II GIF/CF/PCF TYPE 180 Series OPERATION MANUAL

Chapter 4 Operation

• If the biopsy valve is left uncapped during the procedure,

debris or fluids could leak or spray from it, posing an

infection-control risk. When the valve is uncapped, place a

piece of sterile gauze over it to prevent leakage.

If the endoscope is cold, dew condensation may form on the

surface of the objective lens, and the endoscopic image may

appear cloudy. In this case, increase the temperature of the

sterile water in the water container to between 40 – 50°C

(104 – 122°F) and then use the endoscope.

 Air/water feeding

1. Cover the air/water valve’s hole to feed air from the air/water nozzle at the

distal end (see Figure 4.5).

2. Depress the air/water valve to feed water onto the objective lens (see Figure

4.5).

Chapter 4 Operation

 Suction

• Avoid aspirating solid matter or thick fluids; channel or valve
clogging can occur. If the suction valve clogs and suction

cannot be stopped, disconnect the suction tube from the

suction connector on the endoscope connector. Turn the

suction pump OFF, detach the suction valve and remove

solid matter or thick fluids.

• When aspirating, maintain the suction pressure at the lowest

level necessary to perform the procedure. Excessive suction

pressure could cause aspiration of and/or injury to the

mucous membrane. In addition, patient fluids could leak or

spray from the biopsy valve, posing an infection-control risk.

• When aspirating, attach the cap to the main body of the

biopsy valve. The uncapped biopsy valve can reduce the

efficacy of the endoscope’s suction system, and may leak or

spray patient debris or fluids, posing an infection-control risk.

During the procedure, take notice that the suction bottle does

not fill completely. Aspirating fluids into a full bottle may

cause the suction pump to malfunction.

Depress the suction valve to aspirate excess fluid or other debris obscuring the

endoscopic image (see Figure 4.5).

Performing both air feeding and suction at the same time

sometimes makes it easier to remove water droplets from the

objective lens surface.

EVIS EXERA II GIF/CF/PCF TYPE 180 Series OPERATION MANUAL

 Auxiliary water feeding

(for endoscopes with auxiliary water feeding only)

Use sterile water only. Non-sterile water may cause patient

infection.

• Never disconnect the auxiliary water tube from the auxiliary

water inlet during an examination; leave it attached until the

endoscope is precleaned. If the auxiliary water tube is
detached before precleaning, water remaining in the auxiliary

water channel may be spilled on the equipment. This could

cause damage and/or malfunction of the equipment.

• When the auxiliary water tube is not connected to the

auxiliary water inlet, be sure to have the auxiliary water inlet

cap attached to the auxiliary water inlet. Otherwise, patient

debris or fluids that back flowed may drip out of the auxiliary

water inlet.

Chapter 4 Operation

1. Attach a syringe containing sterile water or the water tube from a water

pump to the luer port of the auxiliary water tube. Feed water.

2. When disconnecting the syringe or the water tube from the water pump

during examination, disconnect it directly from the luer port but leave the

auxiliary water tube itself attached.

4.2 Using endo-therapy accessories

For more information on combining the endoscope with particular endo-therapy

accessories, refer to the “System chart” in the Appendix and the instruction

manuals of the accessories. Refer to the accessories’ instruction manuals for

operating instructions.

• Do not use the GIF-N180 for high-frequency cauterization or

laser cauterization treatment. Otherwise, patient injury or
equipment damage may result.

• When using endo-therapy accessories, keep the distance

between the distal end of the endoscope and the mucous

membrane greater than the endoscope’s minimum visible

distance so that the endo-therapy accessory remains visible
in the endoscopic image. If the distal end of the endoscope is

placed closer than its own minimum visible distance, the

position of the accessory cannot be seen in the endoscopic

image, which could cause serious patient injury and/or

equipment damage. The minimum visible distance depends

on the type of endoscope being used. Refer to Section 2.3,
“Specifications” on page 24.

• When inserting or withdrawing an endo-therapy accessory,

confirm that its distal end is closed or completely retracted

into the sheath. Slowly insert or withdraw the endo-therapy
accessory straight into/from the slit of the biopsy valve.

Otherwise, the biopsy valve may be damaged and pieces of

it could fall off.

• If the insertion or withdrawal of endo-therapy accessories is
difficult, straighten the bending section as much as possible

without losing the endoscopic image. Inserting or

withdrawing endo-therapy accessories with excessive force

may damage the instrument channel or endo-therapy

accessories cause some parts to fall off and/or cause patient

injury.

• If the distal end of an endo-therapy accessory is not visible in

the endoscopic image, do not open the distal end or extend

the needle of the instrument. This could cause patient injury,

bleeding, perforation and/or equipment damage.

70

EVIS EXERA II GIF/CF/PCF TYPE 180 Series OPERATION MANUAL

Chapter 4 Operation

• When using endo-therapy accessories, always use the

widest possible angle. When the image is magnified, it may
not be possible to see the position of the accessory in the

endoscopic image. This could cause patient injury, bleeding

and/or perforation (when using the image magnification

function of the video system center CV-180).

• When using a distal attachment, the distal end of the

endoscope becomes longer and its outer diameter is larger.

Handle the endoscope carefully so as not to cause

perforation or other patient injury. When performing

endoscopic treatment using this equipment, take extra care.

• When using a biopsy forceps with a needle, confirm that the

needle is not bent excessively. A bent needle could protrude
from the closed cups of the biopsy forceps. Using such a

biopsy forceps could damage the instrument channel and/or

cause patient injury.

• When using an injector, be sure not to extend or retract the

needle from the catheter of the injector until the injector is

extended from the distal end of the endoscope. The needle

could damage the instrument channel if extended inside the

channel, or if the injector is inserted or withdrawn while the

needle is extended.

Insertion of endo-therapy accessories into the endoscope

• Do not insert endo-therapy accessories forcibly or abruptly.

Otherwise, the endo-therapy accessory may extend from the
distal end of the endoscope abruptly, which could cause

patient injury, bleeding and/or perforation.

• It is easier to insert an endo-therapy accessory into the

instrument channel port if the biopsy valve’s cap is detached
from the main body (see Figure 3.11 on page 45). As a result,

the open biopsy valve can reduce the efficacy of the

endoscope’s suction system, and may leak or spray patient

debris or fluids, posing an infection-control risk. When not

using an endo-therapy accessory, attach the cap to the main

body of the biopsy valve.

EVIS EXERA II GIF/CF/PCF TYPE 180 Series OPERATION MANUAL

71

Chapter 4 Operation

• When the biopsy valve’s cap is detached from the main body,

it may cause patient debris or fluids to leak or spray from the

endoscope, posing an infection-control risk. When the biopsy

valve’s cap has to be detached, place a piece of sterile gauze
over it to prevent leakage.

• Do not let the endo-therapy accessory “hang down” from the

biopsy valve. Doing so can create a space between the

accessory and the valve’s slit or hole and/or damage the
valve, which can reduce the efficacy of the endoscope’s

suction system, and may leak or spray patient debris or

fluids, posing an infection-control risk.

• When inserting an endo-therapy accessory, hold it close to
the biopsy valve and insert it slowly and straight into the

biopsy valve. Otherwise, the endo-therapy accessory and/or

biopsy valve could be damaged. This can reduce the efficacy

of the endoscope’s suction system, and may leak or spray

patient debris or fluids, posing an infection-control risk.

1. Select endo-therapy accessories compatible with the instrument from the

“System chart” in the Appendix. Refer to the accessories’ instruction

manuals for operating instructions.

2. Hold the UP/DOWN and RIGHT/LEFT angulation knobs stationary (the

GIF-N180 has only the UP/DOWN angulation control knob).

3. Confirm that the tip of the endo-therapy accessory is closed or retracted into

its sheath and insert the endo-therapy accessory slowly and straight into the

slit of the biopsy valve.

• Do not open the tip of the endo-therapy accessory or extend

the tip of the endo-therapy accessory from its sheath while

the accessory is in the instrument channel. The instrument

channel and/or the endo-therapy accessory may become
damaged.

• Hold the endo-therapy accessory close to the biopsy valve

and insert it straight into the biopsy valve using slow, short

strokes. Otherwise, the endo-therapy accessory could bend
or break.

72

4. Hold the endo-therapy accessory approximately 4 cm from the biopsy valve

and advance it slowly and straight into the biopsy valve using short strokes

while observing the endoscopic image.

EVIS EXERA II GIF/CF/PCF TYPE 180 Series OPERATION MANUAL

• When the tip of the endo-therapy accessory extends

approximately 1 cm from the distal end of the endoscope, the

accessory will appear in the endoscopic image.

• When the accessory appears in the endoscopic image, it

may also reflect the light from the endoscope and/or cast its

shadow in the endoscopic image. This does not indicate a

malfunction (for GIF-N180 only).

Operation of endo-therapy accessories

Operate the endo-therapy accessory according to the directions given in its

instruction manual.

Withdrawal of endo-therapy accessories

Chapter 4 Operation

• Patient debris might spray when the endo-therapy

accessories are withdrawn from the biopsy valve. To prevent
this, hold a piece of gauze around the accessory and the

biopsy valve during withdrawal.

• Do not withdraw the endo-therapy accessory if the tip is open

or extended from its sheath; patient injury, bleeding,
perforation and/or instrument damage may occur.

• Withdraw the endo-therapy accessory slowly and straight out

of the biopsy valve. Otherwise, the valve’s slit and/or hole

could be damaged. This can reduce the efficacy of the
endoscope’s suction system, and may leak or spray patient

debris or fluids, posing an infection-control risk.

• If the endo-therapy accessory cannot be withdrawn from the

endoscope, close the endo-therapy accessory and/or retract
it into its sheath, then carefully withdraw both the endoscope

and the endo-therapy accessory together under endoscopic

observation. Take care not to cause tissue trauma.

Withdraw the endo-therapy accessory slowly while the tip of the endo-therapy

accessory is closed and/or retracted into its sheath.

Chapter 4 Operation

Use of non-flammable gases (for CF/PCF models only)

Performing treatment while the intestines is filled with a

flammable gas could result in an explosion, fire and/or

serious patient injury. If the intestines contains a flammable

gas, replace it with air or a non-flammable gas such as CO

before performing high-frequency treatment or laser

cauterization treatment.

Using CO2 during endoscopic examinations of the colon and

rectum, etc. may reduce post-examination pain.

When a non-flammable gas is used, only water containers MH-970 or MAJ-902

may be used with the endoscope. Carefully follow their instruction manuals.

2

High-frequency cauterization treatment (except GIF-N180)

• If the intestines contains a flammable gas, replace it with air

or a non-flammable gas such as CO

high-frequency cauterization treatment. Otherwise, fire or

explosion could result.

• Not all parts of the endoscope are electrically insulated.

When applying high-frequency current, there is a danger of

unintentional diathermy burns. Always wear electrically

insulating chemical-resistant gloves.

• Never emit high-frequency current before confirming that the

distal end of the high-frequency endo-therapy accessory is in

the endoscope’s field of view. Also confirm that the electrode

section and the mucous membrane in the vicinity of the
target area are at an appropriate distance from the distal end

of the endoscope. If the high-frequency current is emitted

while the distal end of the endo-therapy accessory is not

visible or too close to the distal end of the endoscope, patient

injury, bleeding and/or perforation as well as equipment

damage can result.

before performing

Prepare, inspect and connect the electrosurgical unit and electrosurgical

accessories as described in their instruction manuals.

The application of high-frequency current may interfere with
the endoscopic image. This does not indicate a malfunction.

EVIS EXERA II GIF/CF/PCF TYPE 180 Series OPERATION MANUAL

Laser cauterization treatment (except GIF-N180)

• Performing treatment while the intestines is filled with a

flammable gas could result in an explosion, fire and/or

serious patient injury. If the intestines contains a flammable

gas, replace it with air or a non-flammable gas such as CO

before performing laser cauterization treatment.

• To avoid patient injury, burns, bleeding and/or perforation as

well as damage to the endoscope, do not activate laser

radiation before confirming that the tip of the laser probe

appears in the proper position in the endoscopic image. Keep

an appropriate distance between the target and the

endoscope’s distal end and always use the lowest power
output possible.

Chapter 4 Operation

2

• Before inserting or withdrawing the laser probe, return the

UP/DOWN and RIGHT/LEFT angulation control knobs to

their neutral positions (see Figure 3.6 on page 41) so that the

bending section will be straight. If it is bent, the instrument

channel and/or the laser probe may be damaged.

• Allow the tip of the laser probe to cool down before pulling it

back into the instrument channel. If the laser probe is

withdrawn while hot, channel damage may occur.

• Do not use a damaged laser probe. A laser probe with a

damaged sheath or distal end may cause patient injury

and/or equipment damage.

Prepare, inspect and connect the laser unit and laser probe as described in their

instruction manuals.

4.3 Withdrawal of the endoscope

• If blood unexpectedly adheres to the surface of the insertion

tube of the withdrawn endoscope, carefully check the

condition of the patient.

• If it becomes impossible to withdraw the transnasally inserted
endoscope, pull its distal end out of the mouth, cut the

flexible tube using wire cutters, and after ensuring that the

cut section will not injure the body cavity or nasal cavity of the

patient, withdraw the endoscope carefully. Therefore, always

prepare wire cutters in advance.

1. When using the image magnification function of the video system center

CV-180, release the function.

2. Aspirate accumulated air, blood, mucus or other debris by depressing the

suction valve.

3. Turn the UP/DOWN and RIGHT/LEFT angulation locks to the “F ”

direction to release them (the GIF-N180 has only the UP/DOWN angulation

lock).

4. Carefully withdraw the endoscope while observing the endoscopic image.

When the splinting tube is used, withdraw both the endoscope and the

splinting tube together from the patient’s anus (for CF/PCF models only).

Chapter 4 Operation

Transporting outside the hospital

Transport the endoscope in the carrying case.

Always clean, disinfect or sterilize the endoscope after

removing it from the carrying case. If the endoscope is not

cleaned, disinfected or sterilized, it could pose an

infection-control risk.

• The carrying case cannot be cleaned, disinfected or
sterilized. Clean and disinfect or sterilize the endoscope

before placing it in the carrying case.

• Do not attach the water-resistant cap when transporting the

endoscope, to avoid damage to the endoscope caused by
changes in air pressure.

• Before putting the endoscope in the carrying case, always

make sure that the insertion tube is set to the most-flexible

condition. Putting the endoscope in the carrying case while
the insertion tube is rigid could damage the endoscope (for

endoscopes with flexibility adjustment only).
