Orthopedic minimally invasive universal reduction device

Abstract

The application discloses a kind of orthopedics minimally invasive universal reset device, it is related to medical instrument technical field, including fixed rod, first fixed component, moving assembly and second fixed component;Fixed rod is equipped with rack and horizontal groove;First fixed component realizes multi-angle fixed kirschner wire by first connecting rod and first mounting rod;Moving assembly realizes quick sliding positioning by cooperating with gear rack and pinion of shift plate, realizes accurate traction reset and self-locking by worm and bevel gear meshing transmission of runner;Second fixed component realizes universal angle adjustment by ball joint, and vacuum adsorption and sealing rubber ring extrusion are carried out by the threaded transmission drive piston of gear ring and moving plate, realize the double locking of ball joint.The application realizes the quick positioning of kirschner wire in orthopedics minimally invasive surgery, universal angle adjustment and stable traction reset, solves the problems of slow adjustment speed, angle limitation and complicated operation of existing orthopedic reset device, significantly improves the efficiency and reset accuracy of minimally invasive surgery.
