Dual-polarline resectoscope

Abstract

The invention relates to a dual-polarline resectoscope and solves problems of positive-negative joints mis-insertion, poor sealing effect and inconvenient assembling and detachment of a resectoscope in the prior art. The resectoscope comprises an external sheath, an internal sheath, an operator, an endoscope and an electrode main body, wherein a main body sealing sleeve covers the endoscope and the electrode man body; the main body sealing sleeve is connected into an internal sheath back end connection port in a sealed way; the main body sealing sleeve is provided with an endoscope hole and an electrode hole; an electrode sealing sleeve is further embedded into the inner wall of the back end of the electrode hole; the back end of the electrode sealing sleeve is provided with a sealing wrapping head; and a dual-polar socket and a dual-polarline cooperated with dual-polar socket are arranged on the operator. The wrapping head can movably and tightly wrap up the outer wall of an electrode main body during the movement of the electrode main body, so water leakage can be prevented and sealing effect can be further improved; by the use of the dual-polarline, connection of positive wires and negative wires can be unnecessary, so a structure is simplified and operator work can be facilitated; and wrong connection can be also prevented.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a bipolar resectoscope with good sealing performance, anti-miswiring, and simple and quick assembly. Background technique [0002] With the development of modern medical technology, it has become a very common medical technology to use electrocution to go deep into the patient's body for examination and operation. Generally, the resectoscope needs to be performed in an electrolyte environment. The cutting electrode is inserted into the working guide groove through the natural body hole and enters the cavity. After the cutting electrode is activated, plasma is generated to vaporize or coagulate the tissue. At present, there are still some shortcomings in the resectoscope. Firstly, two sockets, anode and cathode, are generally installed on the resectoscope. When in use, the operator is easy to misconnect the plug, causing harm to the patient. Secondly, because the resectos...
