Abstract
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.
