Abstract: 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.

Abstract: A resectoscope includes an electrode arrangement having at least one electrode and being connected to a contact at a proximal end region of the electrode arrangement; a retaining body mounted on the resectoscope that is movable in the direction of movement of the electrode arrangement and includes an electrode mounting for accommodating the end region of the electrode arrangement; and a cable with a plug body for fixing to the retaining body while making contact with the contacts. The retaining body has a plug receptacle for fixing the plug body by an insertion movement aligned at right angles to the direction of movement of the electrode arrangement. In the position which is reached at the end of the insertion movement, the plug body can be turned into an end position where it is blocked by the plug receptacle against a movement in the opposite direction to the insertion movement.

Abstract: A resectoscope having a laser fiber, which is mounted to be longitudinally displaceable and emits light at its distal end as well as having a carriage, which is mounted so that it is longitudinally displaceable on the resectoscope and has an elongated bore, which is stationary on the carriage in at least some regions and is designed to receive the laser fiber, and having a clamping device designed for connecting the laser fiber to the carriage by clamping, wherein the clamping device has a clamping body, which is mounted so that it is movable on the carriage across the bore and in which a region of the bore that is moved with the clamping body is arranged.
