The Conmed Sabre 180 Electrosurgical Unit
(ESU) provides the modern surgicenter and office
clinic with a broad range of electrosurgical capa­bilities. It is suitable for use in minor, general
and laparoscopic procedures. The bipolar option
extends applications to gynecological, neurologi­cal and other microsurgery. CONMED offers
other higher powered ESUs better suited to the
most demanding procedures, such as transurethral
resections.

Salient features of this ESU include:

•DIGITAL KNOB POWER CONTROLS:
Combines the speed and ergonomics of analog
controls with the precision of pushbuttons.

•LAST USED SETTINGS ON POWER UP:
Power and mode settings used during previous
procedures are automatically restored when unit is
turned on, minimizing preop setup effort.
Optionally, the unit may be configured to default
to zero power and standard modes. In either case,
the previously used A.R.M. single/dual pad mode
selection appears every power up.

•ASPEN RETURN MONITOR: When used
with A.R.M. or compatible dual-foil return elec­trodes, the Aspen Return Monitor (A.R.M.) pro­vides an extra margin of safety against possible
patient burns at the return site. The Resistance
Indicator displays the resistance of the patient
measured between the conductive contacts of the
return electrode. This information can be used to
note high risk patients and to indicate a loss of
electrode contact with the patient. The A.R.M.
also allows use with non-monitoring electrodes
when set to the Single Foil mode.

•ISOLATED OUTPUT CIRCUITRY: This fea­ture minimizes the probability of alternate ground
site burns. Complies with all current internation­al standards for RF leakage.

•INDEPENDENT OUTPUTS: Only one out­put is active at a time for maximum patient and
operator safety. Interlocked controls prevent
mishaps in the event of conflicting commands.

•POWER ADJUSTABLE WHILE ACTIVAT­ED: The power settings can be adjusted while the
unit is activated. The change is limited to the
greater of +

5W or + 25% of the power setting

at the beginning of the activation.

•VERSATILE, EFFECTIVE, MONOPOLAR
CUTTING: A selection of three different crest
factors provide the user with a range of hemosta­sis, from negligible for minimal-damage biopsies,
through a moderate blanch for ordinary incisions
to near-coag quality heavy hemostasis. A broad
load regulation helps sustain an effective cutting
arc in both wet and dry fields.

•CIRCUIT REDUNDANCY: This feature, in
conjunction with a fault tolerant design, provides
a wide safety margin against catastrophic failures.

•MICROPROCESSOR CONTROL: Provides
the user with a superior degree of safety and con­trol in solid state electrosurgery. The programmed
intelligence of the microprocessor has been
exploited to provide accurate, well controlled
therapeutic power, digital power display, and a
comprehensive set of internal diagnostics which
continually guard against the consequences of an
internal failure. Internal fault isolation simplifies
troubleshooting to ensure a minimum delay in
returning the unit to service.

•FULGURATION/COAGULATION: Up to
80 watts of high crest factor coagulation with
over 5000V peak to peak output voltage provides
effective contact dessication as well as easy fulgu­ration of diffuse bleeders.

•IMPROVED BIPOLAR: Optionally available
as a footswitched alternate coagulation mode, the
Sabre 180 bipolar is designed to start quickly and
conclude gracefully with minimal sparking and
tissue sticking.

•SIMPLIFIED CONTROLS: The user may
command the full range of capabilities of the
Sabre 180 by means of a few easily understood
controls.

1.1 PRECAUTIONS

The safe and effective use of electrosurgery is
dependent, to a large extent, upon factors under
the control of the operator, and not entirely con­trollable by the design of this equipment. It is
important that the instructions supplied with this
equipment be read, understood, and followed in
order that safety and effectiveness be enhanced.

1.1.1 Precautions in Equipment Preparation

•Visually inspect all accessories before each use to
verify the integrity of insulation and the absence
of obvious defects.

•The Sabre 180 is equipped to connect two
monopolar accessories at one time for the conve­nience of the surgical staff. Despite the fact that
the unit will deliver power to only the command­ed electrodes, unused accessories that are connect­ed should be stowed in a safe, insulated place
such as a non-conductive holster or test tube. We
recommend that accessories not be connected
unless it is known that they will be needed.

•This unit is equipped with a hospital grade, 3
prong, power cordset that meets all of the
requirements for safe grounding of the unit. The
user should verify that the power receptacle which

this unit uses is properly grounded and correctly
polarized. Do not use ground cheater plugs or
extension cords.

•Do not place liquid containers on top of the
unit. Wipe spilled liquids off the unit immediate­ly. To preclude inadvertent entry of liquids, do
not operate this unit except in its normal posi­tion.

•Verify that the return electrode cable is connect­ed to the return electrode connector.

•Do not reuse disposable (single use) accessories.

•Do not use cords as handles; damage to the
insulation and increased risk of burns or other
injury may result.

•This unit is not supplied with all accessories nec­essary for the full breadth of electrosurgical appli­cations. Hazardous conditions may result from
inappropriate selection, connection or use of
accessories. Accessories supplied by CONMED
are safe and effective for use with this ESU when
used according to their accompanying instruc­tions and further instructions in this manual. For
further guidance, refer to “IEC Recognized
Electrosurgical Accessories”, CONMED catalog
number 60-5206-001, supplied with some mod­els, or contact your CONMED representative.

1.1.2 Precautions in Patient Preparation

•Electrosurgery should NEVER be performed in
the presence of flammable anesthetics, flammable
prep solutions, or in oxygen-enriched environ­ments. The risk of igniting flammable gases or
other materials is inherent in electrosurgery and
cannot be eliminated by device design.
Precautions must be taken to restrict flammable
materials and substances from the electrosurgical
site, whether they are present in the form of an
anesthetic or skin preparation agent, or are pro­duced by natural processes within body cavities,
or originate in surgical drapes or other materials.
There is a risk of pooling of flammable solutions
in body depressions such as the umbilicus and in
body cavities, such as the vagina. Any excess fluid
pooled in these areas should be removed before
the equipment is used. Due to the danger of igni­tion of endogenous gases, the bowel should be

1-3

purged and filled with non-flammable gas prior
to abdominal surgery.

•This unit is equipped with the Aspen Return
Monitor (A.R.M.) which verifies that the return
electrode cable is unbroken and connected to the
return electrode and to the electrosurgical unit
when in Single Pad mode. It DOES NOT verify
that a single pad return electrode is in contact
with the patient. When in Dual Foil Pad mode,
the A.R.M. confirms that the total resistance is in
the expected range. Do not depend solely on the
Resistance Indicator in the Dual Foil Pad mode.
Proper application and visual inspection are
required for safe operation.

•The use and proper placement of a return elec­trode is a key element in the safe and effective use
of electrosurgery in monopolar procedures, par­ticularly in the prevention of burns. Follow direc­tions and recommended practices for the prepara­tion, placement, use, surveillance, and removal of
any return electrode supplied for use with this
electrosurgical unit.

•Apply the return electrode to a clean-shaven
surface of the patient that is thoroughly clean and
dry. Avoid placement on scar tissue, bony promi­nences or other areas where pressure points on
small areas might develop.

•Because of the risk of burns, needles should
never be used as return electrodes for electro­surgery. Return electrodes should be placed such
that as much of their conductive area as possible
is in firm contact with an area of the patients’
body that has a good blood supply and as close to
the operative site as is practical. Adhesive-type
return electrodes should be reliably attached with
their entire area in contact with the patients’ body.

•In general, electrosurgical current paths should
be as short as possible and should run either lon­gitudinally or in a diagonal direction to the body,
not laterally and under no circumstances lateral to
the thorax.

•Electrodes and probes of monitoring, stimulat­ing, and imaging devices can provide paths for
high frequency currents even if they are battery
powered, insulated or isolated at 60 Hz. The risk
of burns can be reduced but not eliminated by
placing the electrodes of probes as far away as

possible from the electrosurgical site and the
return electrode. Protective impedances incorpo­rated in the monitoring leads may further reduce
the risk of these burns. Needles should not be
used as monitoring electrodes during electrosurgi­cal procedures.

•The active electrode should not be used in the
vicinity of electrocardiograph electrodes.

•Heat applied by thermal blankets or other
sources is cumulative with the heat produced at
the return electrode (caused by electrosurgical
currents). Risk of a patient injury may be mini­mized by choosing a dispersive electrode site that
is remote from other heat sources.

•When using injection cannulas as electrocardio­graph electrodes, the metal cone must not be
placed on the skin; this also applies to the leads to
monitoring instruments.

•During the use of this RF isolated output unit,
the patient should not be allowed to come in con­tact with metal parts that are grounded or other
conductive surfaces that have an appreciable
capacitance to ground. This will minimize the
possibility of localized burns resulting from stray
electrosurgical currents to the ground.

•Skin to skin contacts, such as between the arm
and the body of a patient, should be avoided by
the insertion of a cloth.

•The use of electrosurgery on patients with car­diac pacemakers or pacemaker electrodes is poten­tially hazardous because the pacemaker may be
irreparably damaged and/or the high frequency
energy of the electrosurgical output may interfere
with the action of the pacemaker and ventricular
fibrillation may occur. Precautions should be
taken to ensure that the patient’s well-being is
maintained in the event of such interference. We
recommend that the Cardiology Department and
the manufacturer of the pacemaker be consulted
for advice before operating on a patient with a
pacemaker. These precautions also apply to oper­ating room personnel with cardiac pacemakers.

•To minimize the possibility of cardiac pacemaker
interference, place the return electrode such that
the electrosurgical current path is as near orthog­onal as possible to the pacer lead.

1-4

1.1.3 Precautions in Use

•The use of monopolar electrosurgery on small
appendages, as in circumcision or finger surgery,
can cause thrombosis and other unintended injury
to tissue proximal to the surgical site. Bipolar
techniques avoid these complications.

•Apparent low power output or failure of the
electrosurgical equipment to function correctly at
otherwise normal settings may indicate faulty
application of the return electrode, failure of an
electrical lead, or excessive accumulation of tissue
on the active electrode. Do not increase power
output before checking for obvious defects or
misapplication. Check for effective contact of the
return electrode to the patient anytime that the
patient is moved after initial application of the
return electrode.

•If a Dual Foil RETURN Alarm is sounded
intraoperatively, visually confirm proper return
electrode attachment to the patient prior to press­ing the Monitor Set Button.

•Electrosurgical leads should not be allowed to
contact the patient, staff, or other leads connected
to the patient.

•The output power selected should be as low as
possible and activation times should be as short as
possible for the intended purpose.

•When uncertain of the proper control setting for
the power level in a given procedure, start with a
low setting and increase as required and/or con­sult your Conmed representative.

•Observe all caution and warning notices printed
on the cover of the unit.

•The staff should never contact electrosurgical
electrodes (either active or dispersive) while the
RF output of the unit is energized.

•The tips of recently activated accessories may be
hot enough to burn the patient or ignite surgical
drapes or other flammable material. Place hot
accessories in a test tube after use. An alternative
is to wait a few seconds after activation for the tip
to cool, and then place the accessory into the sup­plied holster.

•Electrosurgical currents can produce severe elec­trical interference with or damage to other nearby
electronic devices. Physiologic monitors should be
equipped with electrosurgical filters and current­limiting devices (RF chokes). Monitoring elec­trodes should be placed as far as possible from the
surgical site. Video endoscopy equipment, espe­cially camera cables, should have adequate and
undamaged electrical shielding.

1.1.4 Precautions When Testing or Servicing

•This electrosurgical unit should be tested by
qualified maintenance personnel on a periodic
basis to ensure proper and safe operation. We
suggest examination of the unit at least once a
year.

•Refer all servicing to qualified personnel. Your
Conmed representative will be happy to assist you
in getting your equipment serviced.

•High voltages are developed within the unit that
are accessible when the top cover is removed.
These voltages are potentially dangerous and
should be treated with extreme caution.

•Never remove or install any parts with power
on.

•Avoid contact with the output leads when the
unit is activated. Periodically inspect the test leads
used for the output connections for obvious
defects.

•Although this unit will withstand momentary
short circuits on the output, prolonged short cir­cuits may damage the unit. Short-circuiting the
output should be avoided since it is neither neces­sary nor desirable.

•Since the clinical use of electrosurgical units is
intermittent in nature with duty cycles on the
order of 10%, this unit is not designed to operate
for extended periods of continuous output. When
testing, it is recommended that duty cycles be
limited to 50% with maximum activation times
of 30 seconds.

•Life of the equipment will be extended by mini­mizing operating temperature and extreme ther­mal cycles.

This section contains initial installation, prelimi­nary checks and operating instructions for the
Sabre 180.

2.1 INITIAL INSPECTION

Unpack the unit upon receipt and physically
inspect it for any obvious damage that may have
occurred during shipment. We recommend that
this inspection be performed by a qualified bio­medical engineer or other person thoroughly
familiar with electrosurgical devices. If the unit is
found to be damaged, notify the carrier and your
Conmed representative immediately. Retain orig­inal packing material for future storage or ship­ment.

2.2 INSTALLATION

The unit may be placed on any stable cart or
table.

CAUTION: Since the unit depends on natural
convection of air for cooling, it should not be
installed in a cabinet or similar enclosure. If
mounted on a shelf, allow a two inch clear­ance on either side and three inches above the
unit to permit free circulation of cooling air.

The power cordset of the unit should be connect­ed to a properly polarized and grounded power
source whose voltage and frequency characteris­tics are compatible with those listed on the name­plate of this unit.

2.3 PRELIMINARY CHECKS

Prior to initial use of this unit in clinical service it
is recommended that its performance be tested in
accordance with the tests described in the Sabre
180 Service Manual. Results of that testing
should be compared to the results tabulated on
the factory Test Data Sheet that is supplied with
each unit. This data should be retained for future
reference and comparison.

2.3.1 Preliminary Functional Testing

The following checks are recommended upon ini­tial installation of the equipment and prior to
each use of the instrument to avoid unnecessary
delays in surgery. See Figures 2.1 - 2.3 for loca­tion of controls and connectors.

1. Ensure that the Power Switch is OFF.

2. Connect the power cordset to the unit's mains
inlet on the rear panel and to a properly grounded
and polarized mating power receptacle.

3. Connect a two-treadle monopolar foot switch
to the connector on the rear panel of the unit.

4. Connect a handcontrol (hand-switchable pen­cil) to the appropriate connector on the output
panel.

5. Make no connection to the Dispersive
Electrode (Patient Plate) connector at this time.

6. Set the Power Switch to the ON position.
Within one second the machine should respond
by:

a) Sounding each of the four tones in ascending
order over a one second interval.

b) During that interval, displaying "8"s on all five
digital displays.

c) Illuminating all mode activation and error
indicators and all ten resistance indicator bars.

d) After the fourth tone is complete, the machine
should sound two beeps indicating a return fault.
Power and mode selections will change to power­up defaults (see Section 2.6.5 for default option
selection).

Installation & Operation

Section 2.0

2-1

2-2

7. Control Panel Checks:

a) Rotate the CUT and COAG power controls
CW and CCW at least one revolution (36 steps),
verifying that the associated power display
changes in one watt steps for each click of its con­trol.

(NOTE: Displays will not decrement below zero
or increment above maximum rated power for the
selected mode.)

b) Using the MODE pushbuttons, step through
each CUT and COAG mode, verifying that the
associated mode selection indicator illuminates.
Set power to zero in each mode. Leave COAG
mode in monopolar.

(NOTE: Units not equipped with the Bipolar
option do not have COAG mode controls or
indicators).

c) Using the PAD pushbutton, verify that the
SINGLE and DUAL indicators toggle back and
forth. Verify that the RESISTANCE bar graph is
dark in SINGLE mode and that all bars are flash­ing in DUAL mode. Verify that a "two-beep"
alarm sounds after each mode change.

d) Verify that the MACHINE indicator is dark
and that the RETURN MONITOR indicator is
lit in both SINGLE and DUAL modes.

8. Depress the Cut treadle of the foot switch.
The Return Alarm tone should sound and the
RETURN lamp should remain lit. While hold­ing the Cut treadle, rotate the Volume Control
over its full range and verify that there is no sig­nificant change in sound level. Release the Cut
footswitch. The tone should stop and the
RETURN MONITOR should remain lit.

9. Depress the Coag foot switch. The Return
Alarm should sound and the RETURN MONI­TOR should remain lit.

10. On units equipped with Bipolar, select BIPO­LAR COAG. Depress the Coag foot switch.
Verify that the Coag indicator illuminates and the
Coag activation tone sounds. While depressing
the Coag treadle, turn the Coag Power Control

clockwise. The power should increase from zero
to 5 watts. Turn the Coag Power Control coun­terclockwise and the power should decrease to
zero watts.

11. Release the Coag foot switch. The unit
should silence. Then, select MONOPOLAR
COAG.

12. Select SINGLE PAD MODE. Connect a
non-monitoring dispersive electrode to the Patient
Plate connector; verify that the Return lamp and
bar graph extinguish.

13. Depress the Cut foot switch. The yellow
CUT indicator lamp should illuminate and the
Cut tone should sound. While Cut is activated,
rotate the VOLUME control (rear panel) over its
full range, verifying that the tone volume varies
accordingly. Set the volume to a comfortable yet
audible level.

(NOTE: At minimum volume, the activation
tones should remain audible.)

14. While continuing to press the Cut treadle of
the foot switch, depress the Coag treadle. A pul­sating alarm tone will sound. Release the Cut
treadle, continue to press the Coag treadle and
confirm that the sound changes to the Coag tone,
and the blue Coag indicator is illuminated until
the Coag treadle is also released.

15. Activate, one at a time, the Cut and Coag
handswitch controls verifying proper actuation of
each mode.

15a. While depressing the Coag treadle (or
handswitch), turn the Coag Power Control clock­wise. The power should increase from zero to 5
watts. Turn the Coag Power Control counter­clockwise and the power should decrease to zero
watts.

15b. While depressing the Cut treadle (or
handswitch), turn the Cut Power Control clock­wise. The power should increase from zero to 5
watts. Turn the Cut Power Control counterclock­wise and the power should decrease to zero watts.

16. While the single foil electrode remains
connected, select DUAL PAD mode. Verify a

2-3

return alarm and that the bar graph remains dark.
Press MONITOR SET and verify that RETURN
MONITOR remains lit and a "two-beep" alarm
sounds.

17. Replace the single foil electrode with an
A.R.M. compatible dual-foil monitoring elec­trode. While the electrode remains open to the
air, press MONITOR SET. Verify that RETURN
MONITOR remains lit, a two-beep alarm sounds
and that all RESISTANCE bar segments are
flashing.

18. Gradually apply the dual foil electrode to
well-perfused, relatively hair-free skin surface,
such as the medial forearm or posterior calf. As
electrode contact area increases, verify that the
RESISTANCE bar graph segments darken from
right to left.

19. With the dual foil electrode fully applied,
verify that a portion of the RESISTANCE bar
graph remains flashing. Press MONITOR SET,
and verify that the RETURN MONITOR goes
out and that the RESISTANCE bar graph stops
flashing.

20. Gradually peel the dual foil electrode until a
RETURN alarm occurs. Verify that over 2/3rd
of the electrode remains in contact with the skin
at the onset of the alarm. Continue peeling the
electrode slowly, verifying the RESISTANCE bar
graph progressively illuminates.

2.3.2 Preliminary Performance Testing

After the unit passes the Preliminary Functional
Tests of Paragraph 2.3.1, preliminary performance
testing may be conducted. Such testing is best
carried out by use of an electrosurgical generator
tester, as described in Section 4 of the Sabre 180
Service Manual. If such a tester is available, note
that the power display will most accurately indi­cate the power available to a 500 ohm
(Monopolar) and the 50 ohm (Bipolar) nonin­ductive resistor. However, the indicated power to
any such load in the 300-500 ohm (40-80
Bipolar) range should be within 15% of that indi­cated on the digital display.

If no tester is convenient, the availability of
therapeutic current may be ascertained subjective­ly by attempting to cut and coagulate on surro­gate tissue such as a piece of meat or fresh fruit, a
wet bar of soap or a sponge moistened in saline.

Although not recommended, a last resort verifica­tion of available power can be made by drawing
arcs between active and dispersive electrodes or
between the tips of a bipolar forceps. Such a test
will not damage the unit if not carried out for
more than a few seconds, however one should
expect that the electrodes may be damaged due to
the extreme temperatures generated by the arc.
