AI Technical Summary

Technical Problem

In existing techniques, the direction and angle of Kirschner wire insertion are difficult to control precisely during olecranon fracture and osteotomy surgery, which can easily lead to errors, increase surgical time and risks, and make it difficult to control the length and angle of the osteotomy, affecting the subsequent fixation effect.

Method used

A multifunctional guide is designed, including a guide fixing plate and a guide assembly, with positioning holes, fixing holes, an eagle beak hook and an osteotomy guide port. Together with the aiming sleeve and the guide sleeve, it can achieve precise insertion of Kirschner wires and osteotomy guidance, adapting to the anatomical differences of different patients.

Benefits of technology

It improves the accuracy and efficiency of Kirschner wire placement, reduces misoperation and trauma, ensures precise reduction and fixation of fractures, and reduces surgical difficulty and risk.
