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

Abstract

The invention discloses a minimally invasive surgical instrument for bladder polyps, which includes an outer sleeve, an operating tube, a bending manipulator and a docking center. The connection part, the iron core tube part and the rear end tube part are connected in sequence. The bending manipulator includes the operation shell, the conductive plate of the slide seat, the slider and the battery. The high-frequency current butt joint, eyepiece, argon The gas-filled joint, the lighting fiber joint cone and the compensator, the positive electrode tube include the high-frequency current wire, the electrode tip and the wire sheath, and the camera structure includes the lighting fiber, the image transmission fiber and the camera. The invention has the technical advantages of simplified operation, adjustable curvature and greatly reduced operation difficulty.

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...
