Abstract

The invention relates to a urological resectoscope having an axially extending shaft tube, the proximal end thereof being fixed to a main body. A sliding body is proximally positioned in relation to the main body, and can slide in a parallel manner in relation to the axis thereof. Said sliding body comprises a receiver, a fixing device and a contacting device. An electrode which can be subjected to a high frequency, comprising a rigid electrode carrier having one external, insulated conductive wire, can be positioned in the resectoscope in such a way that it can axially slide beyond the distal end of the shaft tube. In the assembly position, said electrode carrier extends through the shaft tube and the main body into the receiver, and can be fixed by means of the fixing device and contacted by means of the contacting device. The inventive resectoscope is characterized in that the fixing device is proximally arranged in relation to the contacting device on the sliding body

Claims2

Dependent claims

A urological resectoscope (1) comprising an axial stem tube (2) which is affixed by its proximal end to a main block (3), a slide block (13) being supported proximally of said main block in an axially parallel displaceable manner relative to said main block (3), said slide block (3) being fitted with a seat (24), an affixing element (31) and an electrically contacting means (28, 29), said resectoscope further comprising within it an hf-loaded electrode (18) which is associated with an electrode support (19) that is fitted with an electrically conducting wire (20) enclosed by an external insulator, said electrode (18) being supported so as to be axially displaceable beyond the distal end (7) of the stem tube (2), where the electrode support (19), when in the assembled resectoscope running through the stem tube (2) and the main block (3) as far as into the seat (24), is affixed by the affixing element (31) and can be made to contact the contacting means (28, 29).

characterized in that
the affixing element (31) is configured proximally relative to the electrical contacting means (28, 29) at the slider block (13).
