Urological resectoscope with insulating body at the outer upper

摘要

Urological resectoscope (1) with a in the distal end area, which has openings (3), tubular, metallic outer shank (2), on which the distal end of a tubular insulating body (7, 27, 37, 47) is secured, with a in the outer shank (2) arranged, the distal end of this sealing said tubular inner shaft (8) and with a the inner shank (8) can be continuous, in the region of the insulator body (7, 27, 37, 47) a cutting loop (15) supporting the electrode carrier (13), wherein the interior of the inner shaft (8) and the intermediate space (12) between the shafts (2, 8) proximally adjoins fluid ports (10, 11) are connected, with the inner shank (8) and the electrode carrier (13), in the proximal direction from the exterior upper (2) can be pulled out, with the exterior upper (2) are connected, the outer shank (2) and the insulating body (7, 27, 37, 47) in a fixing section (6) is in the longitudinal direction, are arranged in overlapping manner and wherein the insulating body (7, 27, 37, 47) distal of the fastening section (6) has a wall thickness which is greater than that of the outer shaft (2), characterized in that the insulating body (27, 47) the same inside diameter as the outer shank (2) comprises.
