General Information - ConMed sabre 180 Service Manual

The Conmed Sabre 180 Electrosurgical Unit
(ESU) provides the modern surgicenter and office
clinic with a broad range of electrosurgical capa-
bilities. It is suitable for use in minor, general
and laparoscopic procedures. The bipolar option
extends applications to gynecological, neurologi-
cal 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 elec-
trodes, the Aspen Return Monitor (A.R.M.) pro-
vides 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 fea-
ture minimizes the probability of alternate ground
site burns. Complies with all current internation-
al standards for RF leakage.
•INDEPENDENT OUTPUTS: Only one out-
put is active at a time for maximum patient and
operator safety. Interlocked controls prevent
mishaps in the event of conflicting commands.

•POWER ADJUSTABLE WHILE ACTIVAT-
ED: 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 hemosta-
sis, 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 con-
trol 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 fulgu-
ration 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.
