Introduction / Device Description / Indications for Use / Contraindications / Warnings
Introduction
The Smith & Nephew VULCAN™ Generator is designed
to provide finely-controlled radiofrequency (RF) energy
for the coagulation, cutting, ablation, and hemostasis
of soft tissue during a variety of surgical procedures.
The generator control unit is specifically designed for
use with Smith & Nephew temperature-controlled
and power-controlled probes.
Device Description
The generator control unit is a line-voltage powered,
radiofrequency generator capable of delivering up
to 200 watts of power. The generator control unit
includes a neutral electrode monitor (NEM) to monitor
split grounding pad contact quality. It is designed to
be used only with Smith & Nephew temperature-
controlled, cutting, and ablation probes and includes
the following features:
• Two RF output modes: Temperature Control
Mode, where the output power is software-
controlled to maintain a specified tissue
temperature; and Power Control Mode, used for
cutting, ablation, and hemostasis.
• Numerical displays for impedance, set power,
delivered power, set temperature, actual
temperature, set cut, set coagulation, and preset
selections.
• Message display for text messages.
• Indicators for electrode type (monopolar or
bipolar), mode (Temperature Control or Power
Control), stand-by, RF power on, RF output type
(cut or coagulation), fault, and split grounding pad
monitoring. NEM monitors the split grounding
pad connection during surgery, discontinuing
RF delivery if a fault in the NEM monitor circuit is
detected.
• A probe recognition system: the generator control
unit automatically selects the appropriate mode
and preset settings for the probe type.
The Smith & Nephew VULCAN Generator software
can be upgraded at the customer’s location
with a Smith & Nephew supplied PCMCIA card.
For information regarding software upgrades,
please contact your authorized Smith & Nephew
representative.
Indications for Use
The Smith & Nephew VULCAN Generator is
indicated for general surgical purposes, including
orthopedic and arthroscopic applications, for
coagulation, ablation, and hemostasis of soft tissues
in combination with Smith & Nephew temperature-
controlled, cutting, and ablation probes.
Contraindications
There are no known absolute contraindications to the
use of electrosurgery.
The use of the Smith & Nephew VULCAN Generator
and accessories is contraindicated, when, in the
judgment of the physician, an electrosurgical
procedure would be contrary to the best interest of
the patient.
Warnings
• It is the surgeon’s responsibility to be familiar
with the appropriate surgical techniques prior
to use of this device.
• Read these instructions completely prior to
use.
• DANGER: Risk of explosion if used in the
presence of flammable anesthetics, skin
preparation agents, or biointestinal gases.
• Hazardous electrical output. This equipment
should be used only by qualified medical
personnel trained in the use of electrosurgery
devices.
• This device has been tested and verified to
comply with the IEC 60601-2-2. This exceeds
the requirements specified by FCC part 18
for ISM equipment. This device is intended
for operation in a medical facility only. Usage
in a residential environment will likely cause
unacceptable RF interference for which the
user is held responsible.
• The generator control unit must be powered
from a properly grounded 120–240 VAC,
single-phase supply. Excessive risk (leakage
current) may result if this equipment is
connected to other than the manufacturer’s
recommended power distribution system.
• Risk of burns or fire. Do not use near
conductive materials such as metal bed parts,
inner-spring mattresses, etc.

61061526 Rev. C VULCAN™ Generator Operations/Service Manual
Warnings (continued)
• Check that the electrical equipment is properly
grounded (i.e. plugs contain a ground prong).
The generator control unit must be plugged
into a hospital-grade AC outlet.
• Safe use of monopolar electrosurgery demands
proper grounding of the patient and proper
insulation between the patient and any metal
surfaces. A split pad with a surface area of at
least 20 square inches (130 cm2) is required.
Valleylab… REM… pads (REF 7209687)
meet this dimensional requirement and are
recommended by Smith & Nephew for use with
the VULCAN™ Generator. Pads with a surface
area of less than 20 square inches may have a
lower dispersive effect. It is the responsibility
of the user to qualify any alternate ground
pad.
• Use of an inadequate ground pad or incorrect
placement of the ground pad may result in a
burn injury to the patient.
• Improper probe usage may result in patient
burns at the return pad. To avoid this, follow
the manufacturer’s Instructions for Use.
• Do not exceed the RF duty cycle for the probe.
• Do not withdraw the probe while energy
delivery is activated; this may result in
an unintended patient burn or ignition of
flammable materials.
• When using RF surgical equipment, keep the
working part of the RF probe’s active electrode
in the field of view to avoid accidental RF
burns. Avoid contact of the probe with metal
parts of the scope and other conductive
accessories by ensuring, before activation of
the RF probe, that the active electrode is at
sufficient distance from the tip of the scope.
• Failure of the radiofrequency surgical
equipment could result in unintended increase
of output power.
• Burns to the surgeon’s hands may be possible
if a probe comes into contact with a metal
instrument or surface.
• Use of electrosurgery in patients with
internal or external pacemakers, implantable
defibrillators or monitoring equipment
may require special considerations. The
attending cardiologist and/or the pacemaker
manufacturer should be consulted prior to
surgery.
• The operating table should be grounded.
• During monopolar electrosurgery the patient
should not come into contact with any metal
parts which are grounded or which have
appreciable capacitance to earth (operating
tables, supports, etc.). The use of anti-static
sheeting is recommended for this purpose.
• During monopolar electrosurgery skin-to-skin
contact (i.e., between the arms and body of
the patient) should be avoided. Insertion of dry
gauze or its equivalent is recommended.
• The probe cables and extension cable should
be positioned in such a way that contact with
the patient or other leads is avoided. Probes
not in use should be stored isolated from the
patient.
• Incorrect actual temperature readings may
result in improper treatment. Verify that the
TEMPERATURE display reads the expected
value (room temperature or body temperature)
prior to treatment. If the TEMPERATURE
reading is not accurate, check the device
and connectors for damage, moisture, or
contamination. Clean or replace as needed.
• If desired tissue effect is not being achieved,
do not increase power beyond the normal
range without first inspecting the integrity of
the probe and neutral (return) electrode.
• To prevent electric shock, unplug the
control unit from the electrical outlet before
attempting to replace the fuses.
• To avoid fire hazard, use only fuses of the
correct type, voltage rating, and current rating.
• To prevent electric shock, do not remove
the control unit cover. There are no user-
serviceable components inside. Dismantling
the equipment will void the warranty. Refer
servicing to qualified Smith & Nephew
personnel.

Nephew arthroscopic radiofrequency probes. Do
not use other devices with the generator control
unit.
• Check the probe and extension cable connections
for the presence of liquid before use or whenever
a probe is connected or disconnected during
a procedure. Liquid may enter the connection
during a procedure. ANY liquid can cause the
connections to short, resulting in erroneous probe
recognition or damage to the probe, cable, or
generator control unit.
• Check the generator control unit’s LCD message
display to ensure that the proper probe
identification and settings are displayed prior to
beginning any procedure.
• Use the lowest RF power setting necessary to
achieve the desired tissue effect.
• This equipment is designed and tested to
minimize interference with other electrical
equipment. However, if interference occurs with
other equipment it may be corrected by one or
more of the following measures:
– Reorient or relocate this equipment, the other
equipment, or both.
– Increase the separation between the pieces of
equipment.
– Connect the pieces of equipment into different
outlets or circuits.
– Consult a biomedical engineer.
• This equipment contains electronic printed circuit
assemblies. At the end of the useful life of the
equipment it should be disposed of in accordance
with any applicable national or institutional related
policy relating to obsolete electronic equipment.
• Inspect all components, including extension
cables and power cord, regularly for wear. Pay
particular attention to extension cable insulation.

WARNINGS:
• DANGER: Risk of explosion if used in the
presence of flammable anesthetics, skin
preparation agents, or biointestinal gases.
• Hazardous electrical output. This equipment
should be used only by qualified medical
personnel trained in the use of electrosurgery
devices.
• This device has been tested and verified to
comply with the IEC 60601-2-2. This exceeds
the requirements specified by FCC part 18
for ISM equipment. This device is intended
for operation in a medical facility only. Usage

• The generator control unit must be powered
from a properly grounded 120–240 VAC,
single-phase supply. Excessive risk (leakage
current) may result if this equipment is
connected to other than the manufacturer’s
recommended power distribution system.
• Risk of burns or fire. Do not use near
conductive materials such as metal bed parts,
inner-spring mattresses, etc.
1. Plug the power cord into the rear panel power
cord connector and a grounded AC power source.
WARNING: Check that the electrical
equipment is properly grounded (i.e., plugs
contain a ground prong). The generator control
unit must be plugged into a hospital-grade AC
outlet.
2. Inspect the footswitch for any obvious defects.
Connect the footswitch cable to the appropriate
connector on the rear of the generator control unit.
3. Prepare the patient using standard technique for
electrosurgical procedures. The patient’s entire
body, including extremities, must be insulated
against contact with grounded metal parts, and
sufficient layers of electrically insulating sheets
should be placed underneath the patient. A
waterproof cover should be placed over the
insulating sheets, with absorbent sheets placed
between the patient and the waterproof cover to
absorb any moisture.
WARNING: The operating table should be
grounded.
4. For monopolar procedures, affix the split
grounding pad to the patient according to the
instructions found in the pad packaging. Select
a well-vascularized application site in close
proximity to the surgical site. Avoid bony or
hairy prominences. Shave, clean, and dry the
application site as needed. Apply the pad firmly,
assuring full adhesion and contact with the
patient’s skin. After the pad is properly applied to
the patient, connect the pad to the NEM connector
on the control unit front panel.
Note: It is important that the split grounding pad
be connected to the generator control unit after
the pad is properly placed on the patient. This
allows the generator control unit to determine an
accurate baseline split grounding pad contact quality
measurement for a particular patient and will allow
the system the greatest resolution in determining if a
loss of split grounding pad contact occurs during the
procedure.
WARNINGS:
• Safe use of monopolar electrosurgery demands
proper grounding of the patient and proper
insulation between the patient and any metal
surfaces. A split pad with a surface area of at
least 20 square inches (130 cm2) is required.
Valleylab… REM… pads (REF: 7209687)
meet this dimensional requirement and are
recommended by Smith & Nephew for use with
the VULCAN™ Generator. Pads with a surface
area of less than 20 square inches may have a
lower dispersive effect. It is the responsibility
of the user to qualify any alternate ground
pad.
• Use of an inadequate ground pad or incorrect
placement of the ground pad may result in a
burn injury to the patient.
• Improper probe usage may result in patient
burns at the return pad. To avoid this, follow
the manufacturer’s Instructions for Use.

Operational Modes / Power Delivery Modes
Operational Modes
Power Up
When the AC power to the generator control unit is
turned on using the power switch on the rear panel,
the generator performs a series of system self-tests
to determine if it is performing properly. The self-tests
include:
ROM checksum
RAM test
Temperature measurement calibration test
RF system test
Display segments and indicators test
If any of the system self-tests fail, the FAULT indicator
on the front panel is illuminated and a continuous
tone sounds. Contact Smith & Nephew if any system
self-test fails.
WARNING: Failure of the radiofrequency
surgical equipment could result in
unintended increase of output power.
Stand-By Mode
Immediately after performing the self-test, the
generator will default to Stand-By Mode. All of the
displays on the front panel will be blanked, and the
generator control unit will not be able to deliver RF
power while it is in Stand-By Mode.
Fault Mode
If a fault is detected at any time during the generator
control unit’s operation, the FAULT indicator light will
illuminate, an alarm will sound, an error code and text
message will be displayed in the message display,
and the generator will enter the Fault Mode. RF
energy cannot be delivered and the control unit must
be powered down then powered up again to exit from
Fault Mode.
Power Delivery Modes
Temperature Control Mode
If the MODE button is pressed once while the
generator is in Stand-By Mode or if a temperature
controlled probe is connected to the generator, the
generator will enter the Temperature Control Mode.
In Temperature Control Mode, the Smith & Nephew
VULCAN™ Generator software automatically adjusts
energy delivery to maintain the tissue temperature
indicated in the SET TEMP display. Only monopolar
temperature-controlled probes may be used in
Temperature Control Mode.
All Smith & Nephew probes are equipped with a
sensor that enables the generator control unit to
detect the type of probe connected. When a probe is
connected, the Smith & Nephew VULCAN Generator
software will read the sensor and automatically adjust
power output and temperature parameters to the
preprogrammed settings for the probe type.
If a probe is not detected, the generator control
unit will default to PRESET “1”, and the SET POWER
and SET TEMP displays will show the power and
temperature values corresponding to this setting.
Power Control Mode
The generator enters Power Control Mode if the
MODE button is pressed once while the unit is
in Temperature Control Mode, or twice while in
Stand-By Mode, or if a cutting or ablation probe is
connected to the control unit.
The user may change the type and amount of
power delivered by adjusting SET CUT (inactive for
ELECTROBLADE™ Resector) or SET COAG (inactive for
GLIDER Articular Cartilage Probe).
All Smith & Nephew probes are equipped with a
sensor that enables the generator control unit to
detect the type of probe connected. When a probe is
connected, the Smith & Nephew VULCAN Generator
software will read the sensor and automatically adjust
parameters to the preprogrammed settings for the
probe type.
If a probe is not detected, the generator control unit
will default to PRESET “10”, and the SET CUT and
SET COAG displays will show the SET CUT and SET
COAG values corresponding to this setting.

Instructions for Use
1. Turn the control unit on using the on/off switch
on the rear panel. The generator will perform a
series of system self-tests to determine if it is
performing properly. If any of these tests fail, the
FAULT indicator will illuminate and a continuous
tone will sound. Contact Smith & Nephew
Customer Service if any system self-test fails.
Inspect the front panel displays for any system
indicator warnings or messages.
After completing the self-tests, the generator will
default to Stand-By Mode. All the displays on the
front panel will be blank and the generator will not
be able to deliver RF power.
2. Connect the selected Smith & Nephew probe
to the probe connector on the control unit front
panel. If the probe includes an integrated cable,
insert the cable connector with the thumb groove
up.
For probes without an integrated cable, connect
the probe to the extension cable. A “click” may be
heard. Tug gently on the extension cable to ensure
proper connection. Connect the other end of the
probe cable into the probe connector.
Note: ELECTROBLADE Resectors with a
two-prong Valleylab plug end can be plugged
into the ELECTROBLADE Adaptor for use with
the VULCAN™ Generator.
3. Verify that the selected probe’s name is
presented on the message display. The generator
software will recognize the probe type by reading
a sensor in the probe and will automatically
switch to the appropriate power output, MODE,
and setting for that specific probe.
WARNING: Burns to the surgeon’s hands
may be possible if a probe comes into
contact with a metal instrument or surface.
CAUTION: Check the probe and extension cable
connections for the presence of liquid before use
or whenever a probe is connected or disconnected
during a procedure. Liquid may enter the connection
during a procedure. ANY liquid can cause the
connections to short, resulting in erroneous probe
recognition or damage to the probe, cable, or
generator control unit.
CAUTION: Check the generator control unit’s LCD
message display to ensure that the proper probe
identification and settings are displayed prior to
beginning any procedure.

4. Confirm that the NEM light is illuminated green. If
illuminated red, check the split grounding pad to
assure full adhesion and contact with the patient’s
skin.
5. If using a temperature-controlled probe, proceed
to step 6. If using a power-controlled probe, skip
steps 6–8 and proceed directly to step 9.
6. For temperature-controlled probes, check the
temperature display to confirm expected values.
WARNING: Incorrect actual temperature
readings may result in improper treatment.
Verify that the TEMPERATURE display reads the
expected value (room temperature or body
temperature) prior to treatment. If the
TEMPERATURE reading is not accurate, check the
device and connectors for damage, moisture, or
contamination. Clean or replace as needed.
CAUTION: Use the lowest RF power settings
necessary to achieve the desired tissue effect.
7. To begin RF energy delivery, depress and hold the
blue COAG footswitch for the type of power to be
delivered, according to the probe’s Instructions for
Use. The green RF POWER ON and blue COAG
indicator lights will illuminate.
WARNING: If desired tissue effect is not
being achieved, do not increase power
beyond the normal range without first inspecting
the integrity of the probe and neutral (return)
electrode.
8. During energy delivery, the generator sounds a
fluctuating tone. The tone pulsates slowly while
probe temperature is ramping up to the SET
TEMP. The tone will sound more rapidly as the
SET TEMP is approached. The tone is rapid and
steady when the SET TEMP is reached and while
it is held. Any variation in tone speed signals the
user that probe temperature is not at the target
temperature.
9. To begin RF energy delivery in the Power Control
Mode, depress and hold the selected footswitch
for the type of power to be delivered, according
to the probe’s Instructions for Use. Select the
yellow CUT pedal for the cut output and the blue
COAG pedal for the coagulation output. The green
RF POWER ON and yellow CUT or blue COAG
indicator lights will illuminate.
Note: During energy delivery in the Power Control
Mode, a steady tone will sound while RF energy is
being delivered. Different tones are generated for
CUT and COAG.
WARNING: Do not exceed the RF duty cycle
for the probe.
10. RF energy delivery may be discontinued at any
time by releasing the footswitch. To resume RF
energy delivery, press and hold the footswitch
again.
WARNING: Do not withdraw the probe while
energy delivery is activated; this may result
in an unintended patient burn or ignition of
flammable materials.

Preventative Maintenance
The following inspections should be performed on an
annual basis to ensure safe operation of the Smith &
Nephew VULCAN Generator.
Inspection of Cables
Inspect the power cable and replace if signs of wear
or abrasion are visible.
Inspection of Connectors
Inspect all connectors on the control unit for signs
of wear or damage. Look specifically for bent or
damaged pins, loose fittings, etc. Contact Smith
& Nephew Customer Service for assistance if any
damage is detected.
Calibration of Temperature
Measurement Circuit
There is no method for the user to alter the
calibration of the temperature measurement
hardware in the field. However, Smith & Nephew
recommends that this calibration be checked on an
annual basis. If it is found to be out of specification,
the device should be returned to Smith & Nephew
for repair.
The generator performs a self-test during power-up
to verify power calibration. There is an internal,
100 ohm resistor which is measured and compared
to its specified value. The generator goes into a Fault
Mode if the calibration is out of specification. In
addition, the thermocouple amplifying circuits are
checked for calibration. However, there is no check
on the “absolute” temperature measured by a
temperature probe; therefore, this calibration must
be manually checked.
Equipment
• Thermometer
• TAC™-S Probe with connecting cable
• Beaker
Procedure
1. Fill the beaker with cool water (10–30° C).
2. Use the thermometer to measure and record the
temperature of the cool water.
3. Turn on the control unit and connect the cable of
the test TAC-S Probe. Verify that the control unit
goes into the Temperature Control Mode. The
TEMPERATURE should display room temperature.
4. Immerse the tip of the TAC-S Probe in the water
and record the actual temperature.
5. Repeat steps 1–4 using hot water (50–90° C).
The TEMPERATURE reading with the TAC-S Probe
should be +/- 3° C of the thermometer reading in
both cases.
If a greater difference is observed, contact Smith &
Nephew for assistance.

Troubleshooting
Generator Control Unit
The generator control unit includes a message
display that provides a text description of any alarm
or fault messages. If the system is not operating as
expected, check the message display.
WARNING: To prevent electric shock, do not
remove the control unit cover. There are no
user-serviceable components inside. Dismantling
the equipment will void the warranty. Refer
servicing to qualified Smith & Nephew personnel.
Alarm and Fault Messages
The generator detects two types of error conditions:
alarms and faults.
An alarm is generated to inform the user that the
output of the device is being disabled to prevent
injury to the patient or damage to the device. Alarms
are automatically cleared once the alarm condition
returns to its acceptable value.
A fault is a more serious error condition and typically
occurs as a result of a hardware failure, such as
a stuck footswitch or a conversion circuit that is
out of calibration. The FAULT indicator light will be
illuminated, and requires that the control unit be
reset by cycling power. Refer to the “Troubleshooting”
section for those faults that can be corrected by the
user. If a fault other than those listed occurs, contact
Smith & Nephew for assistance.
