Resectoscope clamping device for transurethral resection of prostate

Abstract

The invention discloses a resectoscope clamping device for transurethral resection of the prostate, and relates to the technical field of medical equipment. The resectoscope clamping device comprises a fixing mechanism, a rotating mechanism and a clamping mechanism, wherein the fixing mechanism comprises a connecting block; the rotating mechanism comprises a motor, a cross-shaped connecting block, a coupling, a deep groove ball bearing, a bearing positioning table, a big retaining ring, an angular contact ball bearing, a sleeve, a small retaining ring and a rotating connecting plate; and the clamping mechanism comprises a motor, guide rail baffle plates, a section material baseplate, a coupling, a coupling stop dog, a deep groove ball bearing, an optical axis, a ball screw, a feed screw nut, a sliding block, a push rod, a clamping block and a movable clamping block. The resectoscope clamping device has the beneficial effects that an operating knife is fixed on the clamping mechanism; a motor of the rotating mechanism drives the clamping mechanism and the operating knife to rotate for changing the resection angle of the operating knife; the motor of the clamping mechanism is used for driving assemblies of the clamping mechanism to complete the telescoping movement of an electric resection loop of the operating knife; the two-degree-of-freedom movement of the operating knife is realized; and the working intensity of doctors is reduced.

Description

Technical field [0001] The present invention relates to the technical field of medical equipment, in particular to a transurethral resection mirror clamping device for prostate surgery. Background technique [0002] In the traditional transurethral resection of the prostate, the doctor holds a scalpel, manually adjusts the angle of the scalpel, pushes the scalpel loop, and at the same time, steps on the power pedal to complete the prostatectomy. It can be said that for a longer operation, such work is more intensive for doctors. In recent years, there have also been some researches and developments on scalpel holders, but they cannot meet the two degrees of freedom requirements of scalpel rotation and movement at the same time. The present invention better solves the problem of degree of freedom. In the current research, S. Russo of Harvard University in the United States mentioned in the document "A Novel Robotic Platform for Laser-Assisted Transurethral Surgery of the Prostat...
