Intramedullary compression nail plate for olecroanon

Abstract

The invention relates to an intramedullary compression nail plate for olecroanon. The intramedullary compression nail plate at least comprises an intramedullary main nail, an inner bushing screw, an anti-rotation screw, an olecranon nail plate and a guider, wherein an axial spiral compression hole is formed in the near-end end face of the intramedullary main nail, and a locking hole is formed in a nail body at the tail end; the inner bushing screw can be screwed in the axial spiral compression hole of the intramedullary main nail, and the tail of the inner bushing screw is provided with a nut cap; the anti-rotation screw can be locked in the locking hole of the intramedullary main nail; the olecranon nail plate is used for exerting force and compressing on fracture lacerated ends by the pushing of the inner bushing screw and is an arc-shaped plate, the appearance of the olecranon nail plate is identical with the anatomical appearance of the olecroanon, and an opening hole through which the inner bushing screw passes is formed in the olecranon nail plate; the guider is in an 'L' shape; and a traverse positioning hole for conveying the anti-rotation screw into the locking hole of the intramedullary main nail is formed in an axial rod body, and an axial positioning device for conveying the inner bushing screw into the axial spiral compression hole of the intramedullary main nail is formed in a traverse rod body. According to the intramedullary compression nail plate for treating olecroanon fracture, a good treatment effect can be achieved, so that patients can start to perform functional training in the postoperative early state.

Description

Technical field [0001] The present invention involves a medical device, especially in an intramedamic nail plate for the fracture of the ulnar eagle. Background technique [0002] The ruler eagle mouth fracture is one of the common damage to the elbow joint.Adults are more common.It is mainly caused by indirect violence.For example, if you fall to the ground, the violence is transmitted from the remote to the proximal, the elbow joint is slightly flexed, and the triceps suddenly shrink to cause the eagle mouth to fracture.The fractures are mostly horizontal or oblique. Because the fracture line is cut into the ruler of the ulnar eagle mouth, it is required to anatomy during treatment, fixed and firm, early activities, and look forward to restoring good elbow joint functions. [0003] At present, the treatment of ulnar eagle mouth fractures at home and abroad usually include: [0004] 1. Rehabilitation of closed techniques, fixing plaster.Generally, functional exercises will be st...

Problems solved by technology

However, the surgical incision is long, the tissue exposure area is large during the operation, and the soft tissue damage is heavy, which destroys the blood supply around the fracture, which not only affects the fracture healing, but also increases the chance of infection
