Two-way fixing steel plate and diaphysis fixing system

Abstract

The invention relates to a two-way fixing steel plate and a diaphysis fixing system. The two-way fixing steel plate comprises a steel plate body, wherein the steel plate body is used for placement from the front side of a diaphysis, and has a structure matched with the front lateral surface of the diaphysis for fixing and attachment of the fractured end of a bone; at least two pairs of guide holes for penetrating through first locking screws respectively are formed in the structure, matched with the front lateral surface of the diaphysis, of the steel plate body at angles at which an intramedullary nail is clamped by each first locking screw through which the guide holes penetrate to control rotation and axial stability of the intramedullary nail. According to the two-way fixing steel plate, the guide holes of the steel plate body are formed at specific angles, so that the guide holes can be matched with the first locking screws to implement supporting, protection, rotation prevention and axial stability of a part at the fractured end of the bone of the diaphysis to further enhance fixing reliability after reduction, and assistance in stable reduction and healing of the fractured part can be effectively ensured.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a bidirectional fixation steel plate and a backbone fixation system for bone nonunion or fracture nonunion after bone fracture. Background technique [0002] In the prior art, after a fracture occurs, according to the degree of stability of the fracture end, it can basically be divided into two categories: stable and unstable. For stable fractures, external fixation methods such as plaster, splint, brace, and traction brake are usually used to maintain stable fixation and eventually heal through manipulative restoration; for unstable fixation, surgical treatment is required, including internal fixation systems and fractures. External fixation system, the internal fixation system is further divided into nail plate fixation system and intramedullary nail fixation system. However, regardless of the above-mentioned treatment methods, large-scale follow-up studies have shown ...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims at problems such as instability of the broken end of the fracture, nonunion or delayed union of the fracture after the intramedullary nail system is used to fix the backbone fracture in the prior art, and proposes a two-way fixed plate structure, which uses a The matching structure of the plate body, and a number of guide holes for passing through the locking screws are set on the plate body, and further the rotation and axial stability of the intramedullary nail can be controlled by cooperating with the first locking screw, so that the fracture end can be stably fixed, Prevent dislocation of fracture ends, and ensure accurate positioning, reduction and healing of auxiliary fracture sites
