Neutral electrode operation

Only for monopolar treatments neutral electrodes are required to return the HF current from 

the active electrode of the HF instrument back to the electrosurgical generator. In bipolar 

electrosurgery both electrodes, the active and the return electrode, are implemented within 

the HF instrument.

Improper connection between the neutral electrode and the patient’s skin surface may cause 

burns. 

 

• When attaching a neutral electrode, consider the safety notes as described below.

 

• For further details on neutral electrodes, refer to the specific instructions for use of the 

neutral electrode.

If the output power of the electrosurgical generator exceeds the permissible power of a 

neutral electrode for infants (patient weight 0...15 kg), then this will result in severe burns to 

the patient.

 

• Only use output settings within the permissible range of output power for the neutral 

electrode. Refer to the instructions for use of the neutral electrode.

If the size of the neutral electrode is too small for the patient, then this could result in burns 

to the patient.

 

• Choose the largest possible neutral electrode that is adequate for the patient.

 

• Consider the size of the neutral electrode particularly for obese patients.

 

• Consider the size of the neutral electrode particularly if high output power levels are 

needed.

If non-split type neutral electrodes are used, then the contact quality monitor does not work. 

In case that the non-split type neutral electrode detaches from the patient, then no warning 

signal sounds. This could result in burns to the patient.

 

• Only use split type neutral electrodes. Refer to the section “Compatible neutral electrodes” 

on page 89.

If the HF instrument is at the treatment site when a neutral electrode failure is indicated, then 

tissue might be cut mechanically with the HF instrument. This could result in bleeding and 

perforation.

 

• Note that the output of energy automatically stops when the CQM indicates a neutral 

electrode failure.
