Abstract

The invention relates to an elastic system for an acromioclavicular joint, and belongs to the technical field of implantation material in a human body. The elastic system for the acromioclavicular joint is composed of a main plate, an upper assistant plate, a lower assistant plate, an elastic deformation structure and an elastic buffer structure. The main plate and the upper assistant plate are connected and fixed through the two ends of the elastic deformation structure. The main plate and the lower assistant plate are connected and fixed through a connecting support plate and the elastic buffer structure. Fixing holes are formed in the main plate and the upper assistant plate. According to the elastic system for the acromioclavicular joint, elastic fixing of the acromioclavicular joint is achieved through the elastic structure, the main plate, the upper assistant plate and the lower assistant plate, the acromioclavicular joint can recover to an original dissection corresponding relationship, fixing is firm and reliable, installation and positioning are simple, convenient and accurate, postoperative restoration loss does not occur, and the therapeutic effect is good. The elastic system for the acromioclavicular joint solves the problems that an existing hook steel plate structure appears unhooking after the operation, unsatisfied operational restoration and the postoperative restoration loss are prone to occur, and fixing of the acromioclavicular joint fixing plate on an acromion is not firm which influence the therapeutic effect seriously.

Description

technical field

[0001] The invention relates to an elastic fixation system for acromioclavicular joints, which belongs to the technical field of implants in human body. Background technique

[0002] For acromioclavicular joint dislocations and fractures of the outer end of the clavicle with a large displacement, surgical treatment is generally performed. The current surgical methods for the treatment of dislocation of the acromioclavicular joint and fractures of the outer end of the clavicle generally include: Kirschner wire tension band surgery, coracoclavicular ligament repair and reconstruction, arthroscopic button plate reconstruction, hook plate fixation, etc. Because the hook plate fixation technique only needs to insert the pointed hook head of the hook plate under the scapula, and then fix the plate body with screws, the operation is relatively convenient. It has developed rapidly in recent years and has gradually become the first choice for surgical treatment of var...
