Bladder polyp minimally invasive surgical instrument

Abstract

The invention discloses a bladder polyp minimally invasive surgical instrument. The instrument comprises an outer sleeve, an operating tube, a bending operator and a butt joint pivot, wherein the outer sleeve is a hollow tube, the operating tube is formed by sequentially connecting a front end tube part, a magnetic matching part, a bending connecting part, an iron core tube part and a rear end tube part from front to back, the bending operator comprises an operation shell, a sliding base conductive plate, a sliding block and a battery, a high-frequency current butt joint, an ocular lens, an argon inflation connector, an illumination optical fiber connector cone and a compensator are arranged in the butt joint pivot, a positive electrode tube comprises a high-frequency current wire, an electrode end and a wire protection layer, and a camera structure comprises an illumination optical fiber, an image transmission optical fiber and a camera. The instrument has the technical advantages that the operation is simplified, the curvature is adjustable, and the operation difficulty is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to minimally invasive surgery devices for bladder polyps. Background technique [0002] Bladder polyp is a kind of excess tumor growing on the bladder mucosa. When the polyp festers and bleeds, it will cause frequent urination, urgency, pain, and hematuria. At present, medical high-frequency electric knife is mainly used to remove bladder polyps. . [0003] High-frequency electrotome (high-frequency surgical device) is an electrosurgical instrument that replaces a mechanical scalpel for tissue cutting. It heats the tissue when the high-frequency and high-voltage current generated by the effective electrode tip contacts the body, and realizes the separation and coagulation of the body tissue, thereby achieving the purpose of cutting and hemostasis. The circuit is composed of a high-frequency generator in the high-frequency electrosurgical unit, patient plates, connecting wi...

AI Technical Summary

Problems solved by technology

For polyps in the lower part of the bladder, especially near the urethral orifice, it is difficult for the existing high-frequency electrosurgical knife to target the polyps, requiring surgical personnel to assist in oppressing the patient's abdomen or urethra, greatly changing the patient's position, changing the shape of the bladder, etc. , not only troublesome, but also increase the surgical risk during the cutting process
