Cosman G4 Radiofrequency Generator Service Manual (SPI
11291
Rev A)
Section 1
WARNING:
Potentially hazardous conditions may exist when accessories of similar
connector types are combined. Use only appropriate accessories certified by an
accredited test body.
WARNING:
Never proceed in a temperature monitored procedure if the generator
does not read body temperature before you begin delivering RF energy.
WARNING:
Raise the temperature slowly, particularly with large electrodes.
Displayed temperature lags behind the actual temperature due to the thermal mass
of the electrode.
WARNING:
Verify functional safety of the device before each use, using the
guidelines detailed in this manual.
WARNING:
The output of any electrode may change when patient output is being
delivered. Do not move electrode(s) or change electrode connections to the
generator when patient output is being delivered to any electrode.
WARNING:
To avoid unanticipated stimulation to the patient, do not cycle the
generator power or turn the generator power on while the patient is connected to the
generator.
NOTICE:
Always have spare electrodes and cables on hand in case a problem
arises with the first one during a procedure. Reuseable cables and accessories
should be periodically tested.
NOTICE:
Use of DGP-PM ground pad with a stainless steel RF Cannula may
provide a galvanic potential (the “battery effect”) resulting in a single stimulation
pulse at the time the TC Electrode is placed into an RF Cannula. This should be
anticipated, and does not present any risk or danger to the patient.
NOTICE:
Always record the wattage readings that correspond to a given
temperature for a given technique. This gives extra guidance and helps Cosman
Medical diagnose problems.
WARNING:
Proper electrode placement should be verified using anatomical
landmarks, sensory and motor stimulation techniques, fluoroscopic guidance,
Impedance reading, and good clinical judgment before RF lesion making procedures
are initiated.
