6 1061526 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 cm
2
) 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.
