Abstract
An electrode unit for a medical resectoscope for the electrosurgical resection of tissue in a fluid-filled cavity in a patient includes an elongated rod-shaped electrode shaft which on its distal end has an electrode support and a cutting electrode that is fastened to the electrode support and may be acted on by alternating current. A spatula element that is designed for supporting tissue and that extends distally beyond the cutting electrode is situated on the electrode support, the spatula element having two support flanks that extend distally on both sides of the cutting electrode to form outer edges of the spatula element, at least one of the support flanks having an inwardly directed indentation to form a constriction in the area of the cutting electrode.
