WARNING
• Electrosurgery should not be used within
approximately 4.5 meters of persons with
active implantables, such as pacemakers,
cochlear implants, or nerve stimulators,
as functions of these devices may become
impaired or permanently damaged.
• To reduce the risk of unintended tissue
damage allow a 10 to 15 second cool down
period between cuts in the same area for
heat to dissipate safely.
WARNING
To reduce the risk of accidental burns, consider
the following precautions:
• Do not use PerFect TCS II in the presence of
flammable anesthetics or explosive gases.
• Metal conducts radio frequency energy
just as it conducts electricity. Remove
partial dentures if removable and check
the area for fixed partial dentures. Metal
restorations can conduct energy beyond the
anesthetized area and cause discomfort to
the patient.
• Take care that metal restorations, bone, or
teeth do not come into contact with active
electrodes. While fleeting contact will not
be detrimental, extended contact may result
in damage. All instruments used during
electrosurgery should be made of a non-
conducting plastic material. Cotton rolls
or gauze pads used in the patient’s mouth
should be kept moist during electrosurgery.
Remember to deactivate the electrode each
time the electrode sheath is removed from
the operative site and before it is cleaned or
changed. Skin-to-skin contact (for example
between the arms and body of the patient)
should be avoided by insertion of dry gauze
for example.
• When high frequency surgical equipment
and physiological monitoring equipment is
used simultaneously on the same patient, all
monitoring electrodes should be placed as
far as possible from the surgical electrode.
Needle monitoring electrodes are not
recommended. In all cases, monitoring
systems incorporating high frequency,
current limiting devices are recommended.
• Position cables to the surgical electrodes in
such a way that contact with the patient or
other leads is avoided.
• Store electrodes out of reach of the patient.
• Apparent low output or failure to function
correctly at the normal operating settings
may indicate faulty application of the
neutral electrode or poor contact at its
connections.
WARNING
• The use of flammable anesthetics or oxidizing
gases such as nitrous oxide and oxygen
should be avoided. Non-flammable agents
should be used for cleaning or disinfecting.
Solvents of adhesives should be allowed to
evaporate before the application of high-
frequency electrosurgery. Some material
may be ignited by sparks produced in
normal use of the equipment (for example,
cotton wool and gauze when saturated with
oxygen). Endogenous gases may be ignited
by electrosurgery.
• Regularly inspect the accessories,
particularly the electrode sheaths and
cables, for possible insulation damage.
• The electrode sheaths used with the
electrosurgical device have a limited life
expectancy and should be replaced after
twenty (20) autoclave cycles or sooner,
upon the appearance of any signs of wear
or erosion.
• Use only accessories supplied by Coltène/
Whaledent intended for use with this
equipment. The active electrode and handle
is 100% hi-pot tested to 3000 VAC. Peak
voltage to the active electrode may reach
450V and must be rated to 675V at 3.68
MHz. The dispersive electrode normally does
not receive significant voltage but must be
insulated to 4000 VAC.
• Failure of HF (high frequency) surgical
equipment or excessive electrical interfer-
ence could result in an unintended power
output increase, decrease or activation.
In the case of electrical interference,
de-energize or increase distance to the
equipment causing interference. Connection
to a different power circuit may also reduce
interference.
• Where HF (high frequency) current could
flow through a relatively small cross section
of the body it may be desirable to use
bipolar techniques not available with this
equipment.
Anesthesia
Local or general anesthesia must be used with all electrosurgical
procedures. As with any other surgical device, the patient may
experience temporary post-operative pain from the use of
electrosurgery after the anesthetic effect has diminished.
Control of odor and viral plume
Odors and viral plume caused by electrosurgery must be minimized
by using a high speed, high volume evacuator between the patient’s
mouth and nose.
Contraindications
Do not use on patients with active implantables. Do not contact
metal restorations with the electrode tip.
