摘要：
A bipolar resectoscope has an inner shaft with an insulating insert at its distal end and an electrode transporter that can be arranged in the inner shaft. A first electrode is longitudinally moveable in the electrode transporter and has a proximal end that can be connected to a first connection of a high-frequency generator and a second electrode that can be connected at its proximal end to a second connection of the high-frequency generator. A circumferential electrically conductive electrode surface (29) is exposed transverse to the longitudinal axis (28) of the inner shaft (2) and is connected to the distal end (31) of the second electrode (5) on the inner side (30) of the insulating insert (8). The exposed electrode surface (29) of the insulating insert (8) is on the side (34) facing away from the longitudinal axis (33) of the insulating insert, and is insulated electrically toward the inside.
