Problems solved by technology

The plug body may loosen or loosen easily, resulting in poor or interrupted connection
It is very important to turn on the problem when working at high frequency, because it may cause electric shock and burnt
In addition, it poses a risk to reliable surgical practice

Embodiment Construction

[0019] 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 .

[0020] 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 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.

Description

technical field [0001] The invention relates to a resectator of the type stated in the preamble of claim 1 above. 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 elect...
