Orthopedic Kirschner wire positioning guide with quick lock switch

Abstract

The invention discloses an orthopedic Kirschner wire positioning guide with a quick-lock switch, which includes an operating table, a lifting unit, a steering unit, and a guiding unit. The lifting unit includes a supporting sleeve, an adjustment rod, a lifting sleeve, and a quick-locking switch. The side wall of the lifting sleeve is made with a connecting seat, and a quick lock switch is assembled on the connecting seat. The steering unit includes a cylinder body, and the lower gasket, sphere, upper gasket, locking block, cover plate, locking Knob assembly, the cylinder body is provided with a first fixed arm, the end of which is provided with a guide ring, the guide ring is connected and fixed with the upper end of the adjustment rod, the lower end of the ball is provided with a second fixed arm, and the lower end of the second fixed arm is provided with a sleeve The guide unit includes a guide target sleeve, a sliding arm integrated with the guide target sleeve, and a guide sleeve. The slide arm can be movably inserted in the sleeve, with reasonable design, accurate positioning, and suitable for needle insertion and fixation in various directions. Effectively prevent the deviation of the Kirschner wire when it penetrates into the human body.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an orthopedic Kirschner wire positioning guide with a quick lock switch. 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 f...

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
