Inspection of the distal cover

• The distal cover has not been sterilized prior to shipping.

Using a distal cover that has not been disinfected or sterilized

may result in patient infection.

• Should the slightest irregularity be suspected when

inspecting the distal cover, do not use it. A defective distal

cover could fall off during the examination. Continuing the

examination after the distal cover has fallen off may cause

patient injury by the exposed distal end of the endoscope.

• Only the distal cover (MAJ-311) can be used with

TJF-160VR. If the TJF-160VR is used in combination with a

wrong distal cover, it may fall off the distal end during the

examination. Continuing the examination after the distal

cover has fallen off may cause patient injury by the exposed

distal end of the endoscope.

1. Confirm that the metal insert of the distal cover is intact (see Figure 3.10).

Inspection of the mouthpiece

Do not use a mouthpiece that is damaged, deformed or

reveals other irregularities. Doing so may cause patient injury

and/or equipment damage.

Placing the mouthpiece in the patient’s mouth before the

procedure prevents the patient from biting and/or damaging

the endoscope’s insertion tube.

1. Confirm that the mouthpiece is free from cracks, deformation or

discoloration (see Figure 3.11).

2. Using your fingers, check for excessive scratching or other irregularities on

Attaching the distal cover

• Never use the endoscope unless the distal cover is properly

attached to the distal end. If the distal cover is not attached

correctly, it may slip off or fall off the distal end during the

examination. This could result in thermal injury when the

endoscope is used with high-frequency endo-therapy
accessories. And, continuing the examination after the distal

cover has fallen off may cause patient injury by the exposed

distal end of the endoscope.

• If a distal cover with cracks or pinholes is used, it could fall off

during the examination and/or, it may cause thermal injury
because an electric current leaks from cracks or pinholes

when high-frequency cauterization treatment is performed.

Never use a distal cover with cracks or pinholes but replace it

with a new one.

Chapter 3 Preparation and Inspection

• Do not put silicone oil, olive oil, or products containing

petroleum-based lubricants (e.g.Vaseline) on the distal cover

or the distal end. Silicone oil may cause deterioration of the

distal cover. If the distal cover is damaged this way, it may

slip off or fall off during the examination. Continuing the

examination after the distal cover has fallen off may cause
patient injury by the exposed distal end of the endoscope. It

could also result in thermal injury when used in combination

with high-frequency endo-therapy accessories.

When attaching the distal cover, gently hold the bending

section as close to the distal end as possible. Forcefully

grasping other parts of the bending section can damage the

mechanism of the bending section or deform its covering.

Chapter 3 Preparation and Inspection

Inspection of remote switch

Depress every remote control switch and confirm that the specified functions

work normally.

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

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

isopropyl alcohol.

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.

Inspection of the air feeding function

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

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.

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, an irregularity in the air feeding

function may be suspected. If the endoscope is used while

air is continuously being 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.

40

EVIS EXERA TJF TYPE 160VR OPERATION MANUAL

Chapter 3 Preparation and Inspection

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 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.

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.

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 on the objective lens and clears the

endoscopic image.

Chapter 3 Preparation and Inspection

Inspection of the suction function

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.

• 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.

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.

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 operation. During operation, 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.

44

EVIS EXERA TJF TYPE 160VR 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.

− Insertion or withdrawal while the endo-therapy accessory

extends from the distal end of the endoscope.

− Insertion or withdrawal while the bending section is locked
in position.

− Insertion or withdrawal with excessive force.

− Insertion or withdrawal while the forceps elevator is

raised.

• 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”.

− 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.

Continued use of the endoscope under these conditions

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

• If an abnormal endoscopic image/function occurs and returns

to its normal condition by itself, the endoscope may have

malfunctioned. Continuous use of such an endoscope may

cause repetition of the abnormality, and it may not return to

its 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.

• If the forceps elevator cannot be lowered while using an

endo-therapy accessory, stop the procedure immediately and
contact Olympus on keeping the condition.

• If the distal cover should fall off the distal end during the

examination, or seems to fall off, immediately stop the

examination, and slowly withdraw the endoscope from the
patient. Continuing the examination after the distal cover has

fallen off or seems to fall off may cause patient injury by the

exposed distal end of the endoscope.

EVIS EXERA TJF TYPE 160VR OPERATION MANUAL

Chapter 4 Operation

4.1 Insertion

Set the brightness of the light source to the minimum

necessary to perform the procedure safely. If the endoscope

is used for a prolonged period at or near maximum light

intensity, vapor like smoke may be observed in the
endoscopic image. This is caused by the evaporation of

organic material (remaining blood, moisture of stool and so

on) 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 of

the endoscope with a lint-free cloth moistened with 70% ethyl
or isopropyl alcohol, reinsert the endoscope and continue the

examination.

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 and the elevator control lever 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).

Figure 4.1

EVIS EXERA TJF TYPE 160VR OPERATION MANUAL

Insertion of the endoscope

• Keep the elevator control lever moved all the way in the

opposite direction of the “ U” direction while inserting or

withdrawing the endoscope into or from the patient. If the

elevator control lever is moved all the way in the “ U”

direction and the forceps elevator is raised while inserting or
withdrawing the endoscope into or from the patient, this may

cause patient injury.

• Do not put silicone oil on the distal cover. Silicone oil may

cause deterioration of the distal cover. A deteriorated distal

cover may not be attached correctly and it may slip off or fall
off the distal end during the examination. Continuing the

examination after the distal cover has fallen off may cause

patient injury. It could also result in thermal injury when used

in combination with high-frequency endo-therapy

accessories.

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.

• 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 Figure 4.2).

Angulation of the distal end

1. Move the elevator control lever in the opposite direction of the “ U”

direction until it stops.

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

tube.

3. Place the mouthpiece between the patient’s teeth or gums, with the outer

flange on the outside of the patient’s mouth.

4. 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.

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 and may impair the action 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.

• 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 knobs 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.

Air/water feeding and suction

• 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.

• 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.

 Air/water feeding

Chapter 4 Operation

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

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

airflow regulator on the light source and add sterile water till

the upper bound of the specified water level in the water

container.

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

regulator on the light source and attach a new air/water

valve.

 Suction

Chapter 4 Operation

• 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 4.3).

Performing both air feeding and suction at the same time

sometimes makes it easier to remove water droplets from the

objective lens surface.

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.

• 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 injury and/or equipment

damage. The minimum visible distance depends on the type
of endoscope being used. Refer to Section 2.3,

“Specifications”.

• 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.

• Do not insert endo-therapy accessories without the forceps

elevator being raised. If they are inserted without the forceps

elevator being raised, the accessory cannot be observed in
the endoscopic image and it may cause patient injury.

52

EVIS EXERA TJF TYPE 160VR OPERATION MANUAL

Chapter 4 Operation

• Do not insert or withdraw an endo-therapy accessory by

force when the forceps elevator is raised to its maximum
height. The instrument channel and/or the endo-therapy

accessory may be damaged and patient injury, bleeding

and/or perforation can result. If the endo-therapy accessory

cannot be inserted or withdrawn, move the elevator control

lever in the opposite direction of “ U” to lower the forceps

elevator and insert or withdraw the endo-therapy accessory.

• 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.

• When using the endo-therapy accessory with the cap of the

biopsy valve detached, it is easier to insert the accessory.

But, as a result, it can reduce efficacy of the endoscope’s

suction system, and may leak or spray patient debris or

fluids, posing an infection-control risk. When not using the

endo-therapy accessory, attach the cap to the main body of

the biopsy valve.

• When the cap of the biopsy valve is detached, it may cause

patient debris or fluids to leak or spray from the endoscope,

posing an infection-control risk. When the valve is uncapped,

place a piece of sterile gauze over it to prevent leakage.

EVIS EXERA TJF TYPE 160VR OPERATION MANUAL

53

Chapter 4 Operation

• 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.

• Hold the part which is close to the biopsy valve of the

endo-therapy accessory, and insert it straight, slowly, and

little by little to 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. Move the elevator control lever all the way in the “ U” direction.

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

4. 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.

5. 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. Confirm that the tip of the

endo-therapy accessory contacts the forceps elevator.

54

6. Move the elevator control lever in the opposite direction of the “ U”

direction to lower the forceps elevator. Advance the endo-therapy accessory

slightly and move the elevator control lever in the “ U” direction. Confirm

that the accessory appears in the endoscopic image.

EVIS EXERA TJF TYPE 160VR OPERATION MANUAL

7. Manipulate the elevator control lever to adjust the height of the elevator.

Operation of endo-therapy accessories

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

instruction manual.

Withdrawal of endo-therapy accessories

• Patient debris might spray when the endo-therapy

accessories are withdrawn from the biopsy valve. Apply

gauze to the biopsy valve to prevent patient debris to spray.

• 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.

Chapter 4 Operation

1. Close the tip of the endo-therapy accessory and/or retract it into its sheath.

2. While lowering the forceps elevator gradually, slowly withdraw the

endo-therapy accessory.

Fixing the guidewire

When a wire guided type endo-therapy accessory (endo-therapy accessory

which has a lumen for a guidewire) and a guidewire are used, and only the wire

guided type endo-therapy accessories are exchanged while detaining the

guidewire in the desired position, the guidewire can be fixed at the distal end of

the endoscope supportly. In other words, this function can be used when a wire

guided type endo-therapy accessory is withdrawn from the guidewire detained in
the billiary/pancreatic duct and inserted along the guidewire detained in the

billiary/pancreatic duct. When fixing the guidewire please follow the warnings

below.

• 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.

EVIS EXERA TJF TYPE 160VR OPERATION MANUAL

Chapter 4 Operation

• Do not use a guidewire when its outer surface is damaged,

ripped or torn. Leakage current can be discharged from

damaged parts of the guidewire, which could cause burns to

the patient, operator and/or assistant, damage the
endoscope, equipment and/or endo-therapy accessory.

• Insert and withdraw a wire guided type endo-therapy

accessory slowly and carefully when the guidewire is locked

in the guidewire-locking groove at the distal end of
endoscope. If the endo-therapy accessory is withdrawn or

inserted along the guidewire with excessive force or rapidly

while the guidewire is locked, the following phenomena may

occur. Also do not move the guidewire while it is locked at the

distal end of the endoscope. Otherwise, the following

phenomena may occur.

− The guidewire comes off the guidewire-locking groove

and cannot be fixed at the distal end of the endoscope.

− The guidewire goes deep inside the patient’s body and

patient injury, bleeding and /or perforation can result.

− The outer surface of the guidewire becomes damaged,

ripped or torn, and pieces of the outer surface might fall

into the patient’s body.

− The outer surface of the guidewire is damaged, ripped or

torn, and leakage current can be discharged from

damaged parts of the guidewire, which could cause burns

to the patient, operator and/or assistant, damage the
endoscope, equipment and/or endo-therapy accessory.

• Observe the endoscopic images to confirm that the guidewire

is locked at the distal end of the endoscope when

withdrawing or inserting a wire guided type endo-therapy
accessory. If the guidewire is not locked properly, patient

injury, bleeding and/or perforation can result.

• Observe the X-ray images and slowly insert or withdraw the

wire guided type endo-therapy accessory while the guidewire
is sticking out of it. Otherwise, patient injury, bleeding and/or

perforation can result.

56

EVIS EXERA TJF TYPE 160VR OPERATION MANUAL

Chapter 4 Operation

• Do not withdraw the endoscope if the guidewire is stuck in

the guidewire-locking groove at the distal end. Patient injury,
bleeding and/or perforation can result. In this case, insert a

wire guided type endo-therapy accessory over the guidewire

from its proximal end, while observing the endoscopic

images to confirm that the guidewire does not penetrate

patient tissue. When the endo-therapy accessory passes

through the groove, it removes the guidewire from the
groove.

• The maximum angle of the forceps elevator is slightly

increased compared with conventional duodenoendoscopes,

due to the need to fix the guidewire at the distal end.
Therefore, endo-therapy accessories can be raised higher

than with other conventional duodenoendoscopes. Closely

observe the endoscopic image when using an endo-therapy

accessory with this endoscope, particularly while performing

papillotomy. Do not manipulate the elevator control lever

and/or endo-therapy accessory without closely viewing the

endoscopic image, as patient injury, bleeding and/or
perforation can result.

• The assistant function of the fixation works most effectively

with guidewires with a diameter of ø 0.89 mm (0.035 inch).

• The assistant function of the fixation may not work effectively

in the following conditions.

− If the elevator control lever is not held stationary.

− If the proximal ends of the wire guided type endo-therapy

accessory and the guidewire are not straight.

− If the contrast media in the guidewire lumen of the

endo-therapy accessory is not washed with physiology

salt solution.

− If the wire guided type endo-therapy accessory is kinked,

deformed or damaged.

− If the combination of the guidewire and the wire guided
type endo-therapy is incorrect.

− If an attempt is made to fix more than one guidewire

simultaneously.

− If the position of the distal end of the endoscope and the

papilla is not appropriate for the assistant function of the

guidewire fixation (see NOTE on page 59).

EVIS EXERA TJF TYPE 160VR OPERATION MANUAL

57

Chapter 4 Operation

When the assistant function of the guidewire fixation does not work effectively,

using a guidewire with a length of less than 4.5 m may make it difficult to

exchange the wire guided type endo-therapy accessories. Prepare the guidewire

with a length of 4.5 m or more.

Using a guidewire with a length of 4.5 m or more, wire guided

type endo-therapy accessories can be exchanged without

using the assistant function of the guidewire fixation.

 Withdrawal of wire guided type endo-therapy accessories

1. Insert the guidewire to the proximal end of the guidewire-type endo-therapy

accessory and advance the guidewire until it reaches the desired position

while observing the endoscopic image and X-ray images.

2. When the forceps elevator is lowered, an operator and an assistant work

together to pull the end of the endo-therapy accessory into the endoscope
while observing the endoscopic image and X-ray images.

3. When only the guidewire is extended from the endoscope’s distal end,

slowly move the elevator control lever all the way in “ U” direction until it

stops.

4. The guidewire is fixed in the guidewire-locking groove on the forceps

elevator at the endoscope’s distal end (see Figure 4.4).

Figure 4.4

5. Withdraw the endo-therapy accessory slowly while holding the elevator

control lever stationary so that the elevator and the guidewire do not move

forward to the “ U” direction. Observe the endoscopic and X-ray images

while withdrawing the accessory.

The assistant function of the guidewire fixation may not

function effectively due to the position of the distal end of the
endoscope and the papilla, because the guidewire comes off

the guidewire-locking groove of the forceps elevator by being

bent the guidewire. In this case, change the position of the

distal end (see Figure 4.5).

1. Move the elevator control lever all the way in the “ U” direction slowly until

it stops while only the guidewire is extended from the endoscope’s distal

end.

2. Hold the elevator control lever stationary that it can no longer move forward

in the “ U” direction. Then insert a wire guided type endo-therapy
accessory slowly from the proximal end of the guidewire while observing the

endoscopic image and X-ray images.

3. When the tip of the wire guided type endo-therapy accessory comes in

contact with the forceps elevator, move the elevator control lever in the
opposite direction of the “ U” direction to lower the forceps elevator while

observing the endoscopic images.

4. While observing endoscopic images and X-ray images, an operator and

their assistant should work together to insert the endo-therapy accessory

carefully without moving the guidewire from the desired position.

High frequency cauterization

• If the intestines contain a flammable gas, replace it with air or
a non-flammable gas such as CO

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 endoscopic field of view. Also confirm that the electrode

section and the mucous membrane in the vicinity of the target

area are at an enough 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.

Chapter 4 Operation

• If the distal cover should fall off or slip off the distal end during

the examination, immediately stop the examination, and
slowly withdraw the endoscope from the patient. If the distal

cover falls off or slips off the distal end, do not perform high

frequency cauterization treatment. This could result in

cauterization of body cavity areas outside the endoscopic

field of view.

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 is normal and does not indicate a
malfunction.
