Setting Up the Force 2 Generator for Surgery

Force 2 User’s Guide
Monopolar electrosurgery –
Always apply a patient return electrode to the
patient for monopolar electrosurgery.
Microbipolar electrosurgery only –
Do not apply a patient return electrode if
you plan to use microbipolar electrosurgery only. If you connect bipolar
forceps to the Microbipolar receptacle and activate the forceps, the REM
indicator illuminates. You can use the bipolar forceps with the REM
indicator illuminated.
When a shunt cord (s-cord) will be used –
Some surgical instruments (e.g.,
colonoscopes) have capacitance to ground which allow substantial
leakage current. To safely shunt the current to the generator, use a shunt
cord that requires a special Valleylab adapter, and use a REM patient
return electrode.
Capacitive pads –
Do not use capacitive pads because of the potential of
high impedance at the patient and return pad interface.
Simultaneously using two generators
– If you are using two generators
simultaneously on the same patient, frequently one patient return
electrode has a high positive voltage and the other has an opposite
negative voltage. When this occurs, a voltage potential difference exists
between the patient return electrodes, and the current may flow to one
patient return electrode instead of flowing to both patient return
electrodes. To avoid problems, place the patient return electrode as close
as possible to the site of surgery and to the generator to which it connects.
Ensure that the two patient return electrodes are not touching.
5. Connect the patient return electrode to the generator.
6. Select the power levels and modes.
Select the output and then use the
Up
and
Down
buttons to select the
desired power setting.
7. Connect the electrosurgical accessories to the appropriate
receptacles.
Refer to the instructions for use provided with the accessory before using.
Warning
Using a patient return electrode without the REM safety feature will not activate
the Valleylab REM Contact Quality Monitoring System.
