Anatomical plate for sternoclavicular joints

Abstract

An anatomical plate for sternoclavicular joints, four pieces as a group, comprises a steel plate, which is of a flat sheet structure, the bending of the steel plate is matched with the position between the proximal clavicle and the sternum, one end of the steel plate is a fixed end fixed on the proximal clavicle, the fixed end is provided with a group of (three or five) clavicle-fixing holes using ordinary cortical bone screws, which correspond to the structure of the proximal clavicle, the other end of the steel plate is a fixed end fixed on the sternum, the fixed end is provided with a group of sternum-fixing holes, three in each row, which correspond to the front structure of the manubrium, and screws screwed down in the sternum-fixing holes have a certain angle. The anatomical plate ensures that a simple and reliable internal fixing material according with anatomical features is provided for sternoclavicular joint dislocation and proximal clavicle fracture, so that an effective clinical treatment method is provided for patients with sternoclavicular joint dislocation and proximal clavicle fractures. The anatomical plate is thin, the postoperative appearance is attractive, the screws can be fixed at an angle in the holes, and thereby the holding force of the screws is greatly enhanced.

Description

technical field [0001] The invention relates to a medical device, in particular to a sternoclavicular joint anatomical steel plate. Background technique [0002] Traumatic sternoclavicular joint dislocations (including traumatic proximal clavicle fractures with sternoclavicular joint dislocations) are clinically less common than acromioclavicular joint dislocations. Gave summarized 1603 patients with shoulder girdle injuries. Traumatic proximal clavicle fracture with sternoclavicular joint dislocation) accounts for about 3%. With the modernization of production and transportation, traumatic sternoclavicular joint dislocation (including traumatic proximal clavicle fracture with sternoclavicular joint dislocation) has a tendency to increase significantly in recent years. [0003] Common dislocations of the sternoclavicular joint are divided into two types: anterior dislocation and posterior dislocation, and occasionally superior dislocation. Due to the characteristics of the...

Problems solved by technology

One end of the structure is a hook-shaped structure with a circular cross-section. The hook is inserted into the sternum and hooked into the sternum. This fixation method is complicated to operate, because the front and rear structures of the sternum are exposed, and the operation is relatively risky.

When removing the steel plate, the sternum needs to be exposed before the hook can be removed, which still has a relatively high risk
