Kirschner wire guider

Abstract

The invention discloses a kirschner wire guider.The kirschner wire guider comprises a guider support, a positioning point arranged on the guider support and a guide channel used for controlling the drilling direction of a kirschner wire.The axis of the guide channel can be adjusted to pass the positioning point.The guider can precisely guide the drilling direction of the kirschner wire in surgery, and therefore the success rate of kirschner wire fixing surgery can be effectively increased, and surgery pains of patients can be relieved.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a Kirschner wire 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 and cross-joint fixation. better. [0004] When...

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, and then turn on the electric drill to drive the Kirschner wire into the bone to be fixed, but it is difficult to accurately drive the Kirschner wire into the predetermined angle and position , especially for bones with irregular multi-articular surfaces like the scaphoid, when the angle and position of the implantation are inaccurate, it is necessary to pull out the Kirschner wire and insert it again. One operation often requires multiple implantations, virtually It aggravates the secondary injury, further destroys the blood supply, prolongs the operation time, and affects the treatment effect

It is difficult to grasp the angle and position of inserting the Kirschner wire, so the one-time success rate of Kirschner wire fixation is low
