Abstract

The invention relates to the technical field of medical instruments, in particular to a coracoclavicular fixator which is used for fixing a coracoid and a clavicle when an acromioclavicular joint dislocation or a fracture of a clavicle outer end occurs. The coracoid clavicle fixator comprises a coracoid portion (1), a clavicle portion (2) and fixing bolts (3), wherein the coracoid portion is composed of a coracoid hook (11) and a hook rod (12), the hook rod (12) is provided with a plurality of hook rod screw holes (13), the clavicle portion is composed of a clavicle fixing hook (21) and a link casing pipe (22), the link casing pipe (22) is provided with a plurality of casing pipe screw holes (23), the hook rod (12) of the coracoid portion is inserted into the link casing pipe (22) of the clavicle portion, and then the fixing bolts (3) are inserted into the screw holes to fix the coracoid portion (1) and the clavicle portion (2) to be a whole. The coracoid clavicle fixator is simple in structure, convenient to operate, small in trauma, reliable in reduction fixation and capable of effectively fixing the coracoid and the clavicle, and can meet biomechanics requirements.

Description

technical field [0001] The invention relates to the technical field of medical instruments, and relates to a coracoclavicular fixator used for fixing the coracoid process and the clavicle when the acromioclavicular joint is dislocated or the outer end of the clavicle is fractured. Background technique [0002] Dislocation of the acromioclavicular joint or fracture of the outer end of the clavicle is common clinically. Because it is often accompanied by rupture of the coracoclavicular ligament, the clavicle or the proximal end of the clavicle is displaced upward, and the distal end of the clavicle is often displaced downward by the gravity of the upper limb, requiring surgical reduction and fixation. At present, clavicular hook plate fixation is often used clinically for the fixation of acromioclavicular joint dislocation or fracture of the outer end of the clavicle. The clavicle hook plate (shape structure) is composed of ... and the hook part. The fixation method is to put ...
