Abstract

A bipolar electrode instrument for use in a resectoscope and having an elongated shaft section, through which a first conductor extends, which forms a working electrode to which high-frequency current can be applied at the distal end of the electrode instrument, and a second conductor further extending through the shaft section, which forms a counter electrode in the distal end region of the electrode instrument. The working electrode and the counter electrode are spatially separated from one another in such a way that the distance between them cannot be bridged by a straight conductor which has a length of 6 mm or less. When used in a resectoscope for endoscopic surgery with a cladding tube, the electrode instrument is mounted so as to be longitudinally displaceable inside the cladding tube.
