Erbe ERBOTOM ICC 200 Instruction Manual page 14

The effective contact surface, i.e. the electrical conductive value between the neutral electrode
and the patient must correspond to the HF capacity used, meaning the intensity of the HF current.
Here the effective contact surface means the surface of the neutral electrode which has electrically
conductive contact to the skin of the patient during high-frequency surgery.
a)
Fig.: The neutral electrode must be applied at an appropriate location on the patient's skin using the
entire contact surface available (a). If the neutral electrode has only partial contact to the patient's skin (b),
there is a risk that burning will occur at this location
3.1.5 Unintentional thermal tissue damage due to unsuitable and/or faulty
accessories
It must be ensured that only accessories in perfect condition are used for high-frequency surgery.
Only accessories that are compatible or tested by the unit manufacturer must be used. This
applies both to the active electrodes including cable and plugs, as well as to the neutral electrodes
including cables and plugs.
When using an instrument with electric insulation, it is necessary to be certain that these insulations
are not overloaded and destroyed by overly high electric voltages. The electric output voltages
for the high-frequency surgical unit are indicated for the various cutting and coagulation modes
relative to the possible settings in this instruction manual. The electric strength of the instrument
insulation can be found in the technical data for the instruments or, in case of doubt, can be
requested from the manufacturer of the respective instrument.
All insulation on electrodes, electrode holders, cables, plugs etc. must be in perfect condition.
