Electrosurgical HF generator

摘要

An electrosurgical high frequency (HF) generator comprising a generator circuit that produces an HF current between an active electrode and at least one neutral electrode. During the cutting or coagulating of biological tissue, unwanted tissue heating due to the HF current can be reduced because the electrosurgical HF generator comprises at least one further auxiliary neutral electrode connected in parallel to the neutral electrode.

主权项

1. An electrosurgical high frequency (HF) system for treating biological tissue using an HF current, said electrosurgical HF system comprising:
a generator circuit for generating the HF current, said generator circuit comprising an active output and a neutral output; an instrument for treating the biological tissue using the HF current and connected to the active output; a neutral electrode configured as a return pad and connected to the neutral output to create a first current path through the biological tissue between the instrument and the neutral electrode; and an auxiliary neutral electrode connected to the neutral output to create a second current path though the biological tissue between the instrument and the auxiliary neutral electrode, the auxiliary neutral electrode being configured as a clamping surface of a clamping instrument.
