Resectoscope with novel sealing structure

Abstract

The invention provides a resectoscope with a novel sealing structure. The resectoscope with the novel sealing structure comprises a bipolar electrode and a work element. The bipolar electrode comprises an electrode body, a sealing plug, a binding post and a double-core wire. The tail end of the electrode body is connected with the double-core wire through the binding post, the binding post is fixed to the work element in a matched mode, the sealing plug and the head end structure of the work element are complementary and are fixed in a matched mode, and a complete sealing block is formed. The resectoscope is characterized in that the sealing plug is provided with two through holes, one hole is an endoscope hole, and the other hole is an electrode hole; the endoscope hole is used for an endoscope of the resectoscope to penetrate, and the electrode hole is used for the electrode body to penetrate. The sealing mode solves the problems that abrasion is caused by rigid connection of an inner sheath and the work element and rigid connection of the endoscope and the work element, and accordingly sealing performance is lowered, and meanwhile guarantees sealing reliability of a bipolar electrode assembly.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a resectoscope with a novel sealing structure used in a resectoscope for minimally invasive surgery. Background technique [0002] Prostatic hypertrophy and hyperplasia are common diseases with a high incidence rate in middle-aged and elderly men, and surgical resection is the most effective treatment. The traditional open surgery is to make an incision in the patient's lower abdomen, and then cut the bladder to take out the prostate, which will cause great damage to the normal physiological structure of the urethra. Moreover, most of the benign prostatic hyperplasia is the elderly, they are often accompanied by other serious diseases, and it is difficult to tolerate the trauma caused by open surgery. Pay attention to. Transurethral resectoscope resection of the prostate was invented in developed countries in Europe and the United States. Since this operation does not r...

AI Technical Summary

Problems solved by technology

This sealing method is more reliable than the previous resectoscope equipment. Its disadvantage is that the connection between the inner sheath and the working element, and the connection between the endoscope and the working element are all rigid connections. After repeated use, the contact surface is worn and the sealing performance drop

In addition, the double-core wires 17 are arranged horizontally. During the operation, the double-core wires 17 need to be connected to the power source by bypassing the operating wrist, and the comfort during the operation is not good.
