Folding fixation system for coracoclavicular ligament repair and application method thereof

Abstract

The invention discloses a folding fixation system for coracoclavicular ligament repair. The folding fixation system is characterized by comprising a push rod 1, a folding cross fixator 2, high-strength reconstruction fixation lines 3 and a button fixing plate 4, wherein the push rod 1 is of a hollow structure; the rear portion of the folding cross fixator 2 is installed in the hollow push rod 1; the reconstruction fixation lines 3 penetrate through the folding cross fixator 2 and penetrate out of the tail end of the push rod 1; the button fixing plate 4 is arranged in a bone canal 8 of a patient; and the reconstruction fixation lines 3 are fixed to a clavicle end through the button fixing plate 4. According to the invention, surgical operation can be completed in a minimally-invasive percutaneous manner, exposure of an acromioclavicular joint is not needed, and all the operations can be completed only via one incision with a diameter of about 1.0 cm in a clavicle; the position of the folding cross fixator can be determined through scale marks marked on the push rod, and the implanted folding cross fixator does not need to be turned over, so operation time is shortened, and the painof a patient is relieved.

Description

technical field [0001] The patent of the invention belongs to the field of medical devices, and relates to a coracoclavicular ligament repair folding fixation system for treating acromioclavicular joint dislocation and a method of use. [0002] technical background [0003] Acromioclavicular joint dislocation is a common clinical shoulder injury, accounting for 9% of shoulder injuries, more common in young people, and the incidence rate of men is 5 times that of women. The injury mechanism of acromioclavicular joint dislocation is mainly that the violent energy directly acts on the adducted shoulder joint, causing the acromion to shift inward and downward, resulting in varying degrees of tearing of the acromioclavicular joint capsule and the surrounding acromioclavicular ligament and coracoclavicular ligament. The stability of the acromioclavicular joint is lost, leading to shoulder pain and limited shoulder joint movement, which seriously affects the daily activities of the ...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide an operation method for the present situation that the current treatment of dislocation of the acromioclavicular joint requires open surgery, large trauma, heavy bleeding, cumbersome and complicated operation in flexible fixation, and prone to internal fixation slippage failure. The process is simple, minimally invasive percutaneous reconstruction and repair of the coracoclavicular ligament injury folding fixation system and its use method, to achieve flexible fixation of the acromioclavicular joint and achieve the purpose of minimally invasive treatment of acromioclavicular joint dislocation
