A resectoscope has an elongated shaft tube, an elongated optic arranged therein with a lens at the distal end and an electrode assembly, wherein the electrode assembly in turn includes an electrode arranged at the distal end of the arms of a fork assembly, which are arranged on opposing sides of the lens and are brought together in a transition region to an electrode shaft, wherein the electrode assembly can be extended in the longitudinal direction by a stroke length from a first position, in which the electrode is arranged inside the shaft tube in front of the lens, into a second position in which the arms of the fork assembly protrude out of the shaft tube. The length of the arms of the fork assembly is thereby greater than 1.2 times the stroke length. The electrode assembly is configured correspondingly.

Resectoscope and electrode assembly therefor

High-frequency (HF) tools are used in medicine for manipulating body tissue, using an HF resectoscope. For electrical insulation of an electrode from an electrode support, the ends of the electrode are initially guided through ceramic tubes. These ceramic tubes are sensitive in particular to forces transverse to the longitudinal axis of the resectoscope. Disclosed herein is a high-frequency tool that has increased stability with respect to transverse forces. An electrode has two ends, which for establishing a connection to an electrode support are each insertable into a receiving opening of the ends of the electrode support, or positionable in front of the ends. The electrode is contacted in an electrically conductive manner, at least in the area of a receiving opening, with a conductor wire that is guided in the electrode support.
