ABSTRACT:
A ureter resectoscope with an elongate flexible stem tube (4) of substantial length and small external diameter, of which the distal end piece (5) is made from insulating material and which accommodates an optical unit (6) as well as a rod-shaped instrument carrier (11). The instrument carrier is disposed so as to be longitudinally displaceable parallel to the optical unit and bears on its distal end an electrode (12, 12′) that can be supplied with high-frequency current and, on its proximal end after passing through a bore in a main body (1) disposed on the proximal end of the stem tube, is fixed and electrically contacted on a slider (13) mounted so as to longitudinally displaceable. The instrument carrier is guided in the vicinity of its distal end on the optical unit (6) by a sliding tube (20) A stop (19) is disposed on the optical unit (6) proximally from the sliding tube (20) in a position which, with the instrument carrier (11) retracted until the sliding tube (20) is in abutment against the stop (19), results in a sufficient electrical safety distance between the electrode (12) and the distal top of the optical unit (6).
