Fixing device for treating proximal clavicle fracture and sternoclavicular joint dislocation

Abstract

The invention relates to a fixing device for treating proximal clavicle fracture and sternoclavicular joint dislocation, and belongs to the technical field of medical instruments. The fixing device iscomposed of a clavicle fixing plate, a sternum handle fixing plate and a connecting piece. Fixing holes are formed in the clavicle fixing plate and the sternum handle fixing plate respectively. The clavicle fixing plate and the sternum handle fixing plate are movably connected through a connecting piece, and the sternum handle fixing plate is bent at the end of the clavicle fixing plate. According to the fixing device, through the connecting piece between the clavicle fixing plate and the sternum handle fixing plate, micromotion between sternoclavicular joints can be achieved, and the problemthat an existing common sternoclavicular joint fixing plate limits micromotion of the sternoclavicular joints in all directions, the linkage effect of shoulder joints is affected, and the function ofthe sternoclavicular joints cannot be recovered easily is solved. The fixing device has the advantages of simple structure, convenient implantation, firm and reliable fixation and good stability, andis particularly suitable for treating proximal clavicle fractures.

Description

technical field [0001] The invention relates to a fixation device for the treatment of proximal clavicle fractures and sternoclavicular joint dislocations, belonging to the technical field of medical devices. Background technique [0002] The sternoclavicular joint is the only joint between the upper limb and the trunk. It is composed of the sternal end of the clavicle, the sternotoclavicular notch and the first costal cartilage. It is a saddle joint. The part that constitutes the clavicular end of the sternoclavicular joint is the articular surface, which is located on the enlarged sternal end of the medial end of the clavicle, and there is an imprint of the costoclavicular ligament below it, and the enlarged medial end of the clavicle is called the sternal end. The joint capsule is attached to the periphery of the joint. It is thinner at the front and back, and slightly thicker at the top and bottom. The joint capsule is tough and reinforced by ligaments around it. The st...

AI Technical Summary

Problems solved by technology

In the prior art, Kirschner wires or steel wires are mainly used for fixation, but internal fixation loosening, wandering, and poor stability after reset often occur. However, the internal fixation method of the sternoclavicular joint with a common fixation plate limits the various joints of the sternoclavicular joint. The fretting movement in the direction affects the joint action of the shoulder joint, which is not conducive to the maximum recovery of the function of the sternoclavicular joint.
