This manual provides the set up, operating
instructions and servicing information for the
Excalibur Plus PC™. Electrosurgery can be dan-
gerous to patients, staff, and other equipment if
misused, therefore, please understand and follow
the warnings and cautions that are included in
this manual. Technical specifications, various
characteristic performance curves, and user main-
tenance instructions are also included.
The Excalibur Plus PC!" provides a broad range
of capabilities in a single general purpose electro-
surgical generator. This rugged unit fulfills the
operational and safety needs of the modern oper-
ating room by providing:
* Four monopolar cutting modes.
* Two monopolar coagulation modes.
* Two bipolar modes.
* RF isolated and independent outputs.
* The proven A.R.M.™ contact quality monitor-
ing system.
* Continuous microprocessor monitoring to pro-
vide the safety required by the conscientious user.
Convenience features include:
+ Remote Physician Control of power settings
using standard hand switched pencils (PC mode).
* Independent power setting for each mode.
* Automatic programming restores unit to the
last settings used.
+ Easy programmability to speed set up of the
unit.
General Information
Section 1.0
* Controlled output voltage provides superior cut
independent of tissue impedance.
* Dual activation in non-contact coagulation
modes.
* Ability to change power settings from the con-
trol panel while the unit is activated.
1.1 CAUTIONS
This equipment, in conjunction with connect-
ed accessories, is intended to produce high-
frequency electrical energy for the controlled
destruction of tissue.
Safe and effective electrosurgery is dependent
not only on equipment design, but also on fac-
tors under the control of the operator. It is
important that the instructions supplied with
this equipment be read, understood, and fol-
lowed in order to ensure safety and effective
use of the equipment.
1.1.1 CAUTIONS For Equipment Preparation
+ Use only accessories that meet the require-
ments of Section 1.2 and Figure 2.3.
* Reusable accessory cables should be periodi-
cally function and safety tested in accordance
with the original manufacturer's instructions.
* Visually inspect all accessories before each
use to verify the integrity of insulation and the
absence of obvious defects. In particular, elec-
trode cables and endoscopic accessories should
be checked for damage to the insulation.
* The Excalibur Plus PC™ is equipped to con-
nect three monopolar accessories at one time
for the convenience of the surgical staff.
Unused accessories should be stowed in a safe,
electrically insulated place such as a noncon-
ductive holster, isolated from the patient. We
recommend that accessories not be connected
unless it is known that they will be needed.

rs ec ME
* Use only a hospital grade, 3-prong, power
cord rated to meet the specifications in Section
1.2 and all of the requirements for safe
grounding of the unit. The user should veri-
fy that the power receptacle with which this
unit is used is properly grounded and correct-
ly polarized, and of the proper frequency per
Section 1.2. 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 immedi-
ately. To preclude inadvertent entry of liquids,
do not operate this unit except in its normal
position.
* Confirm that all accessories are properly
connected to the appropriate jacks.
* Potentially hazardous conditions may exist
when accessories of similar connector types are
combined. Be certain that accessories are
appropriate for the type of generator output
used. Use only CONMED/Aspen Labs foot-
switches. Confirm bipolar leads are connected
only to the bipolar jacks. Connecting bipolar
accessories to monopolar outputs may result
in patient injury.
* Do not reuse disposable (single use) acces-
sories.
* Do not use cords as handles; damage to the
insulation and increased risk of burns or other
injury may result.
1.1.2 CAUTIONS For Patient Preparation
* Electrosurgery should NEVER be per-
formed in the presence of flammable anesthet-
ics, flammable prep solutions or drapes, oxi-
dizing gases such as Nitrous Oxide (N70), or
in oxygen-enriched environments. The risk of
igniting flammable gases or other materials is
inherent in electrosurgery and cannot be elim-
inated by device design. Precautions must be
taken to restrict flammable materials and sub-
stances from the electrosurgical site, whether
they are present in the form of an anesthetic,
life support, skin preparation agent, or are
produced by natural processes within body
cavities, or originate in surgical drapes, tra-
cheal tubes, 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 fluid pooled
in these areas should be removed before the
high frequency surgical equipment is used.
Due to the danger of ignition of endogenous
gases, the bowel should be purged and filled
with nonflammable gas prior to abdominal
surgery. To avoid the risk of tracheal fires,
never use electrosurgery to enter the trachea
during tracheotomy procedures.
* Only non-flammable agents should be used
for cleaning and disinfection wherever possi-
ble.
* This unit is equipped with the Aspen Return
Monitor (A.R.M.) which verifies that the
return electrode cable is unbroken and con-
nected to the return electrode and to the elec-
trosurgical 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 Pad mode, the A.R.M. confirms that
the total resistance is in the preset safety
range. Proper application and visual inspection
of the return electrode are required for safe
operation.
* The use and proper placement of a return
electrode is a key element in safe and
effective electrosurgery. Follow manufacturer's
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 over a well vascu-
larized muscle mass that is thoroughly clean
and dry. Clean and shave site as necessary to
provide adequate electrical connection and per
hospital policy. Avoid placement over scar tis-
sue, 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 electro-
surgery. The entire area of the return electrode
should be placed so that the entire conductive
area is in firm contact with an area of the
patient’s body that has a good blood supply
and is as close to the operative site as is possi-

ble. 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 cir-
cumstances lateral to the thorax.
+ Electrodes and probes of monitoring, stimu-
lating, and imaging devices can provide paths
for high frequency currents even if they are
battery powered, insulated, or isolated at
50/60 Hz. The risk of burns can be reduced.
but not eliminated by placing the electrodes of
probes as far away as possible from the elec-
trosurgical 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.
* When high frequency surgical equipment
and physiological monitoring equipment is
used simultaneously on the same patient, any
monitoring electrodes should be placed as far
as possible from the surgical electrodes.
Needle monitoring electrodes are not recom-
mended. In all cases, monitoring systems
incorporating high frequency current limiting
devices are recommended.
* 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 electrosurgi-
cal 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 electrocar-
diograph electrodes, the metal cone must not
be placed on the skin; this also applies to the
leads to monitoring instruments.
* Electrosurgery by it's nature produces signif-
icant levels of electromagnetic interference
(EMI) when the ESU is activated. This EMI
may damage or impair the function of other
electronic equipment in the O.R., especially
that which makes contact with the patient.
Adverse effects can be mitigated by use only of
equipment specifically designed to tolerate
electrosurgical interference. Cables subject to
flexing should be inspected frequently for
shielding integrity.
* The patient should not be allowed to come
into contact with metal parts that are ground-
ed, or have an appreciable capacitance to
earth. Examples of this would be operating
tables, supports, etc. The use of anti-static
sheeting is recommended. It is recognized
that this recommendation may not be practical
during certain procedures (e.g., those in which
uninsulated head frames are used); however,
to maximize patient safety during the use of
electrosurgical devices, such practices should
be minimized.
* Skin to skin contacts, such as between the
arm and the body of a patient, should be
avoided, by the insertion of dry gauze.
* The use of electrosurgery on patients with
cardiac pacemakers, pacemaker electrodes, or
other active implants is potentially hazardous.
The pacemaker may be irreparably damaged
and/or the high frequency energy of the elec-
trosurgical output may interfere with the
action of the pacemaker. Ventricular fibrilla-
tion 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 pacemak-
er. These precautions also apply to operating
room personnel with cardiac pacemakers.
+ To minimize the possibility of cardiac pace-
maker interference, place the return electrode
such that the electrosurgical current path is as
far as possible from the pacer lead.
1.1.3 CAUTIONS For Use
* PLEASE NOTE: Effective November 29,
1991, federal law (U.S.A.) requires that all
healthcare facilities must report to the manu-
facturer of a medical device, any death or seri-
ous injury or illness to a patient related to the

Excel
use of a medical device. Serious injuries ог Ш-
ness involving the use of a medical device
must be reported to the manufacturer of the
device (or to the FDA if the manufacturer of
the device is not known) within 10 working
days of the incident. Summary reports of
such injuries must also be submitted directly
to the FDA twice a year. Patient deaths relat-
ed to the use of a medical device must be
reported to the manufacturer and the FDA.
For further information, please contact the
Regulatory Affairs Department of CONMED
Corporation at 800-552-0138, 303-699-7600,
or FAX [phone].
* A failure of the unit could result in an unin-
tended increase in output power.
* Safe and effective electrosurgery is depen-
dent not only on equipment design, but also
on factors under the control of the operator.
It is important that the instructions supplied
with this equipment be read, understood, and
followed in order to ensure safety and effec-
tive use of the equipment.
* Do not use monopolar electrosurgery on
small appendages, as in circumcision or finger
surgery, as it can cause thrombosis and other
unintended injury to tissue proximal to the
surgical site. Please note ANSI/AAMI
Standard HF-18-1993 which currently con-
traindicates both monopolar and bipolar elec-
trosurgery for circumcisions.
Urologic literature also contraindicates the use
of monopolar electrosurgery for circumcision,
and instead recommends the use of bipolar
electrosurgery where clinically indicated for
hemostasis. Physicians choosing to use bipo-
lar electrosurgery for circumcisions should be
trained in this technique and knowledgeable
of the effects of electrosurgery on tissue of
this nature.
Should you decide that the bipolar electrosur-
gical technique is acceptable for circumcision,
do not apply the bipolar electrosurgical cur-
rent directly to circumcision clamps.
* Apparent low power output or failure of the
electrosurgical equipment to provide the
expected effect at otherwise normal settings
may indicate faulty application of the return
electrode, failure of an electrical lead, or exces-
sive accumulation of tissue on the active elec-
trode. Do not increase power output before
checking for obvious defects or misapplica-
tion. Check for effective contact of the return
electrode to the patient anytime that the
patient is moved after initial application of the
return electrode.
* Studies have shown that smoke generated
during electrosurgical procedures may be
harmful to surgical personnel. These studies
recommend using a surgical mask and ade-
quate ventilation of the smoke using a surgical
smoke evacuator or other means.
* If a Dual Pad RETURN Alarm is sounded
intraoperatively, physically confirm proper
return electrode attachment to the patient
prior to pressing the Monitor Set key. Smooth
hand over pad surface to ensure electrode con-
tact to patient skin. Replace the pad, if neces-
sary.
* Simultaneous activation can be used in both
Standard and Spray monopolar coagulation
modes. Caution should be used as the output
from either active electrode may change as a
result of: activation of a second output, end-
ing activation of an output, or changing the
arc length from an output. Power sharing is
unlikely to be equal because of differences in
tip to tissue distance and other factors. This
unequal power sharing can be enough to stop
power delivery to one tip if the second tip is
close to tissue, and the first tip is somewhat
above the tissue. The motion or deactivation
of one electrode can cause the other electrode
to start delivering power when it had been too
far away from tissue to arc before the first
electrode change. It is recommended that a
second electrosurgical generator be used as a
better alternative when it is necessary to per-
form simultaneous operation.
* Electrosurgical leads (active, bipolar or
return) should not be allowed to contact the
patient, staff, or other electrical leads connect-
ed to the patient.
© 때

* 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 set-
ting for the power level in a given procedure,
start with a low setting and increase as
required and/or consult the manufacturer.
* Observe all caution and warning symbols
printed on the cover of the unit.
* The operating room staff should never con-
tact 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.
* Do not ignore unexpected activation tones.
Check to determine the cause of the tone, oth-
erwise injury can occur.
* Temporarily unused active electrodes should
be stored in an electrically insulated container.
The unused active electrode should never be
placed on the patient. This is especially impor-
tant for laparoscopic procedures.
1.1.4 CAUTIONS For Testing or Servicing
* Service should not be attempted without
reference to sections 3 and 4 of this manual.
* This electrosurgical unit should be tested by
qualified maintenance personnel on a periodic
basis to ensure proper and safe operation. It is
recommended that examination of the unit be
performed at least yearly.
* Refer all servicing to qualified personnel.
Your CONMED representative will be happy
to assist you in getting your equipment ser-
viced.
* High voltages are developed within the unit
that are accessible when the top cover is
removed. These voltages are potentially dan-
gerous and should be treated with extreme
caution.
a
* The high voltage DC power supply in the
Excalibur Plus PC™ is equipped with a bleed-
er resistor to dissipate the charge on the filter
capacitor. However, it takes several seconds
after power is removed to bleed that charge
down to a safe level; it is recommended that at
least thirty (30) seconds be allowed to elapse
before touching or attempting to perform any
maintenance involving the power supply or
power amplifier.
+ 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 momen-
tary short circuits on the output, prolonged
short circuits may damage the unit. Short cir-
cuiting 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.
* The heat dissipation capability of the heat
sink is impaired by activating the Excalibur
Plus PC™ in other than its normal operating
position.
¢ Ensure that the two top cover screws are
tightened, and always perform a power-up
check to confirm a normal power-up sequence
before returning the unit to service.
