Minimally invasive reparation device for acromioclavicular dislocation

Abstract

Provided is a minimally invasive reparation device for acromioclavicular dislocation. Two needle catheters which guide a kirschner wire are connected by a connecting rod, a guide tube provided with a guide hole is arranged on the connecting rod, a coracoid positioning rod moving along the guide hole is provided, a positioning hook plate mounted on the lower portion of the shoulder blade coracoid is arranged at the lower end of the coracoid positioning rod, the two guide holes which coincide with the two needle catheter through holes in axis are formed in the positioning hook plate, and a latch for fixing the coracoid positioning rod to a certain position is arranged on the guide tube. The minimally invasive reparation device for the acromioclavicular dislocation is simple in structure and convenient to use, the wound is small, the security is high, the learning curve of an operation is effectively reduced, the accuracy and security of an operation are improved, and a traditional operation is evolved into a quantified and standardized accurate operation.

Description

Technical field [0001] The invention relates to medical equipment, in particular to a minimally invasive repair device for treating acromioclavicular joint dislocation. Background technique [0002] The acromioclavicular joint is a flat joint of the human shoulder, which can perform micro movements in all directions. Such as figure 1 As shown, the acromioclavicular joint is composed of the articular surface of the acromion 102 of the clavicle 101 and the coracoid process 104 of the scapula 103 of the scapula. The acromioclavicular joint will be injured due to violence during sports. The specific manifestations are scapula setback, acromion shifting, and distal clavicle upturning, causing damage to the ligaments and muscles around the acromioclavicular joint and dislocation of the acromioclavicular joint. For different degrees of acromioclavicular joint injury, different treatment options can be used, such as triangular bandage fixation, medical treatment or surgical repair. Comm...

Problems solved by technology

In recent years, with the popularization of arthroscopic technology, minimally invasive coracoclavicular ligament reconstruction under shoulder arthroscopy has achieved good results. However, the operation process of this method is relatively complicated, and the personal technical level of the surgeon is extremely high. The required growth cycle is long, and it is difficult to master in the short term. At the same time, there is still a lack of special tools for acromioclavicular joint repair, which makes the operation difficult, time-consuming, and difficult to effectively control and grasp, which is not conducive to the operation and the recovery of the patient.
