Abstract

The invention relates to an elastic fixation device for an acromioclavicular joint. The elastic fixation device comprises a clavicle end locking plate, an extremitas acromialis locking plate, polyester fiber loops, polyester fiber loop locks and screws, wherein a steel plate bulge is arranged on each of the clavicle end locking plate and the extremitas acromialis locking plate and is of a cuboid structure; a plurality of polyester fiber loop holes are formed in one side surface of each steel plate bulge; the polyester fiber loops pass through the corresponding polyester fiber loop holes in thesteel plate bulges to connect the clavicle end locking plate and the extremitas acromialis locking plate; a plurality of screw holes are formed in the clavicle end locking plate and the extremitas acromialis locking plate; and the screws are matched with the screw holes. The elastic fixation device has the advantages that the acromioclavicular joint can be elastically fixed, and the elastic fixation device conforms to the biomechanical principle of the joint, and can avoid related complications caused by use of a clavicular hook plate in the past.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an elastic fixation device for acromioclavicular joints. Background technique [0002] Acromioclavicular joint dislocation is a common orthopedic injury. Severe dislocation requires surgical treatment, especially for type III injuries. Due to the complete rupture of the acromioclavicular ligament and coracoclavicular ligament, the distal end of the clavicle is completely displaced. Due to the gravity of the shoulder, conservative treatment is not effective. Good, surgery is often required to repair the ruptured ligament and stabilize the acromioclavicular joint. At present, the dislocation of the acromioclavicular joint is mostly fixed with clavicle hook plate, gram pin tension band, etc. Since the hook end of the clavicular hook plate is inserted under the acromion, it is easy to cause impingement pain, joint stiffness, limited mobility, and shoulder pain during join...
