Clavicula hook inner lock catch guide apparatus

Abstract

The invention discloses a clavicula hook inner lock catch guide apparatus which comprises a handle (1), a handle rod (2), a guide seat (3), a drill sleeve (4) and a Kirschner wire guide sleeve (5), wherein the handle (1), the handle rod (2) and the guide seat (3) are sequentially connected by pins; wherein the handle rod (2) forms an arch, and the guide seat (3) forms a hook shape; one contact end of the guide seat (3) and a clavicula is provided with a hole (31); the drill sleeve (4) is installed on the guide seat (3) by the hole (31); the lower end of the drill sleeve (4) is opposite to an opening of the hook end on the guide seat (3) contacting with a coracoid, and the inner part of the hook end on the guide seat (3) contacting with the coracoid is provided with a groove (32); and the Kirschner wire guide sleeve (5) is sleeved in the drill sleeve (4). The clavicula hook inner lock catch guide apparatus has reasonable structure design, convenient use, and can well assist to a coracoclavicular ligament reestablishing operation of a human body, and the operation belongs to a minimal-invasive operation with high success ratio.

Description

technical field [0001] The invention relates to a medical device, in particular to a clavicle hook inner lock guide used for reconstructing the coracoclavicular ligament of a human body. Background technique [0002] Acromioclavicular dislocation is a common disease in orthopedics, accounting for 12% of shoulder injuries. According to the severity of symptoms, it can be divided into the following six conditions: Type I: Acromioclavicular ligament is broken, coracoclavicular ligament is intact, and the acromioclavicular joint remains stable; II Type: rupture of the acromioclavicular ligament, coracoclavicular ligament injury, subluxation of the acromioclavicular joint; grade III: total dislocation of the acromioclavicular joint. The acromioclavicular and coracoclavicular ligaments are completely broken, with obvious deformities; type IV: total dislocation of the acromioclavicular joint. As above, the dislocated distal clavicle is penetrated and fixed in the trapezius muscle....

AI Technical Summary

Problems solved by technology

There are many types of existing surgical reconstruction methods, but they have the following disadvantages: (1) implants have many complications, including infection, tissue rejection and fracture; (2) high surgical failure rate , the strength of the implant is not enough, and the normal function of the shoulder cannot be restored well; (3) Most of the existing surgical methods adopt the incision repair method, and most of them will leave large scars for the patients after recovery, which affects people's lives.
