Abstract

Beschrieben wird eine HF-Elektrode mit einer isolierten Zuleitung (31), die sich in Richtung der Längsachse eines monopolar arbeitenden HF-Instruments erstreckt, und einem Elektrodenteil, der elektrisch leitend mit der Zuleitung verbunden ist und mit dem zu bearbeitenden Gewebe in Eingriff gebracht wird, und der aus zwei Bügeln (2) und einem zentralen Teil (11) besteht, dadurch gekennzeichnet, daß der zentrale Teil in Art einer Platte ausgebildet ist, die eine Längserstreckung, d.h. eine Erstreckung in Richtung der Längsachse des Instruments bzw. der Zuleitung von 2 bis 6 mm hat, und daß die Bügel aus einem Drahtmaterial mit wesentlich geringerer Längserstreckung bestehen.
