Orthopedic kirschner wire positioning guider capable of being rapidly adjusted

Abstract

The invention provides an orthopedic kirschner wire positioning guider capable of being rapidly adjusted, and relates to the field of medical instruments. The orthopedic kirschner wire positioning guider capable of being rapidly adjusted comprises a workbench; two supporting guide plates are fixedly arranged at the middle end, close to one side, of the upper end face of the workbench; a sliding block is arranged between the two supporting guide plates in a sliding mode; a first electric cylinder is fixedly arranged on the upper end face of the workbench at the lower end of the sliding block; afirst telescopic rod is fixedly arranged at the output end of the first electric cylinder; the top end of the first telescopic rod is fixedly connected to the center of the lower end face of the sliding block; and a second electric cylinder is fixedly arranged on the upper end face of the sliding block. According to the orthopedic kirschner wire positioning guider designed by the invention, the needle feeding height and the horizontal position of a kirschner wire can be accurately and rapidly adjusted through the two electric cylinders, and the needle feeding angle of the kirschner wire can be rapidly adjusted through a first rotating head, a second rotating head and a fixing sleeve, so that a doctor can rapidly and accurately adjust the needle feeding angle after discovering that the needle feeding angle is incorrect during an operation.

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

[0005] Aiming at the deficiencies of the prior art, the present invention provides a rapidly adjustable orthopedic Kirschner wire positioning guide, which solves the inaccurate and inconvenient adjustment of the angle and position of the Kirschner wire penetration during the fixation operation of the orthopedic wire, which leads to the failure of the operation. low success rate
