Kirschner wire locator for orthopaedics

Abstract

The invention relates to the field of medical apparatuses, in particular to a Kirschner wire locator for orthopaedics. The Kirschner wire locator comprises a supporting seat assembly and a regulatingmechanism, wherein the supporting seat assembly comprises concaved frames which are arranged from left to right and sliding rods which are fixedly arranged between notches in each group of the concaved frame; the front ends of the two groups of the sliding rods and the rear ends of the two groups of the sliding rods are separately connected through connecting pieces; an adjusting screw rod is in threaded connection to the middle part of the connecting piece in the front side in a penetrating manner; the regulating mechanism comprises a moving assembly and an angle regulating assembly; the moving assembly comprises a moving frame and arc-shaped guide rails which are symmetrically arranged at the front part and the rear part of the upper side of the moving frame; sliding sleeves which are insleeving connection with the sliding rods for cooperation are arranged at four corners of the moving frame; and the front side of the moving frame is rotatably connected with the rear end of the adjusting screw rod through spherical hinging. The Kirschner wire locator disclosed by the invention is simple in structure; and through rotating the adjusting screw rod and the angle screw rod and movinga rectangular framework, different piercing inclined angles between the Kirschner wire pipe and the bone part of a patient are realized, so that the Kirschner wire can be pierced into the bone part of the patient in a stable sloping angle, and the piercing effect of the Kirschner wire is improved.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a Kirschner wire positioner for orthopedics. Background technique [0002] During orthopedic fixation surgery, due to the long length of the Kirschner wire, the drilling direction is slightly deviated, which will cause a large deviation in the final drilling position, and the expected position cannot be achieved. Usually, the doctor will fluctuate during the operation. The Kirschner wire deflects the tip of the Kirschner wire to a preset direction and then drills in. However, the Kirschner wire has good elasticity, which makes the pulling effect unsatisfactory, and it is often impossible to achieve a one-time success. It needs to be fixed repeatedly, which greatly reduces the efficiency. Therefore, Kirschner wire positioners are often used for auxiliary positioning. [0003] Usually, a Kirschner wire positioner includes a fixing structure and a positioning assembly. The fixing...

Problems solved by technology

[0007] In view of the above-mentioned shortcomings existing in the prior art, the present invention provides a Kirschner wire positioner for orthopedics, which can effectively solve the problem in the prior art that the angle between the positioning component and the fixation structure cannot be adjusted according to the specific fixation angle. And then it is not convenient for the puncture of the Kirschner wire
