Embodiment Construction

[0018] figure 1 A side view of the resectoscope 1 is shown. The resectator 1 basically corresponds to a generally common basic structure. The resector comprises a shaft tube 2 protruding in the proximal direction of a catheter 3 on which a guide plate 4 is fixed. The rod optic 5 passes through the guide plate 4 and the catheter 3 until it enters the shaft tube 2 , by means of which the operating field can be observed from the distal end of the optic 5 .

[0019] Besides the optical component 5 , an electrode assembly 6 is also arranged in the shaft tube 2 . The electrode assembly is thin and extends longitudinally with an insulating sheath along its length. In the region of the distal end, the electrode assembly has an electrode 7 which, in the case of a resectoscope, is designed as a ring which is customary in resectoscopes. Furthermore, a return electrode 10 is provided in the region of the distal end, so that bipolar operation with the two electrodes 7 and 10 is possibl...

Abstract

A kind of cutter, it has: electrode assembly, and electrode assembly has at least one high-frequency charging electrode, and electrode is connected with the proximal end region of electrode assembly with contact; It is supported on the resectator in a moving manner in the direction of motion, the holding body has an electrode sleeve for accommodating the end region of the electrode assembly; In the case of being fixed to the holding body, wherein the holding body has a plug groove, the plug groove fixes the plug body by means of an insertion action, and the insertion action is aligned perpendicular to the moving direction of the electrode assembly. It is characterized in that the plug The plug body and the plug groove are configured such that the plug body can be rotated from a position reached at the end of the insertion action to a final position in which the plug body engages the plug groove to prevent the insertion action opposite movement.

Description

technical field [0001] The present invention relates to a cutter. Background technique [0002] The cutter has a holding body that can be pushed by hand, and the electrode can be moved longitudinally by means of the holding body, and the electrode can cut human tissue under high frequency. The main field of application is prostatectomy, where prostatic tissue is resected with a high-frequency cutting ring moving longitudinally from the urethra. Besides the application in urology, other applications of the resectoscope are also known, especially for operations in utero in obstetrics and gynecology. [0003] A resectoscope of the aforementioned type is known from US4919131A. This document generally includes the connection between electric wires and electrode assemblies that deliver high-frequency voltage from the outside. This document shows a plug body which connects the conductors in the wire with the conductors in the electrode assembly. The plug body can be inserted in...
