Quick Adjustable Orthopedic Kirschner Wire Positioning Guide

Abstract

The invention discloses a fast-adjustable orthopedic Kirschner wire positioning guide, which includes an operating platform, a lifting unit, a steering unit, and a guiding unit. The lifting unit is vertically arranged on the operating platform, and the lifting unit includes a lower shell, an upper shell, The first battery, the first circuit board, the motor, the reducer, the screw and the lifting nut that are screwed together are arranged in the lower casing, and the steering unit includes a cylinder, and a lower gasket, a sphere, a The upper washer, the locking block, and the electromagnetic switch, the electromagnetic switch includes a second battery, a second circuit board, a static iron core, an electromagnetic coil, a moving iron core, and a spring, and the second battery, the second circuit board, and the electromagnetic coil form an electric circuit, The guide unit includes a guide target sleeve, a sliding arm integrated with the guide target sleeve, and a guide sleeve. The guide sleeve is composed of a fixing seat and an introducer sleeve, which is suitable for needle insertion in various directions and prevents the Kirschner wire from being damaged when it penetrates the human body. Deviated situation.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a rapidly adjustable orthopedic Kirschner wire positioning guide. Background technique [0002] Fracture refers to a disease in which the bone is partially or completely broken due to trauma or pathology. When treating a fracture, the broken end of the bone that has been displaced after the fracture is usually restored to normal or close to the original normal position. After reset, because it is unstable, it is prone to redisplacement. Therefore, different methods should be used to fix it in a satisfactory position to make it heal gradually. There are two kinds of fixation methods: external fixation and internal fixation. [0003] Kirschner wire fixation is a common method of internal fixation. Kirschner wire fixation is usually used for some unstable fractures. Clinically, Kirschner wire fixation is used for short bones, irregular bones, adjacent joint fracture fixation...

AI Technical Summary

Problems solved by technology

[0004] When fixing the Kirschner wire, it is first necessary to install one end of the Kirschner wire on the electric drill, then turn on the electric drill, and drive the Kirschner wire into the bone to be fixed. The Kirschner wire needs to be inserted accurately according to the predetermined angle and position. During the process, once the doctor’s hand-held electric drill shakes, causing the inaccurate angle and position of the insertion, the Kirschner wire needs to be pulled out and re-inserted. One operation often requires multiple injections, which invisibly aggravates the secondary damage. It further destroys the blood supply, prolongs the operation time, and affects the treatment effect. It is difficult to grasp the angle and position of the Kirschner wire insertion process, so the one-time success rate of Kirschner wire fixation is low
