Abstract

Beim Schneiden oder Koagulieren von biologischem Gewebe mit einem elektrochirurgischen HF-Generator (10), der eine Generatorschaltung (12) umfasst, welche einen HF-Strom zwischen einer Aktivelektrode (30) und mindestens einer Neutralelektrode (40) anregt, kann eine unerwünschte Gewebeerwärmung durch den HF-Strom reduziert werden, wenn der elektrochirurgische HF-Generator (10) mindestens eine zu der Neutralelektrode (40) parallel geschaltete weitere Hilfsneutralelektrode (50, 51, 52) aufweist.
