Medical sternoclavicular joint steel plate for orthopedics department

Abstract

The invention discloses a medical sternoclavicular joint steel plate for orthopedics department, and provides an internal fixation material which is simple in operation, small in injury, capable of ensuring stability after dislocation of the sternoclavicular joint, accelerating repair and healing of peripheral ligaments, and realizing exercising so as to recover the joint functions earlier, and remarkable in treatment effect. According to the technical scheme adopted by the invention, the steel plate comprises a locking steel plate, an upward extending steel plate, a limiter, and a clavicle hook used for hooking the clavicle, wherein the locking steel plate is connected with the clavicle hook by the upward extending steel plate, a plurality of bolts are arranged on the locking steel plate,and the clavicle hook is formed by bending the tail end of the upward extending steel plate; the limiter strides the clavicle hook and is fixed on the clavicle by clavicle bolts at two ends. According to the invention, a new style is developed to design sternum end fixation, the clavicle is fixed by the hooked part at the clavicle end, without damaging the completeness of clavicle cortex, and thesteel plate can slide and has the advantages of being small in trauma, free from interference to mediastinum and the chest, and good in stability.

Description

technical field [0001] The invention belongs to the category of medical devices, and in particular relates to a fixed steel plate which restores the fretting joint stability of the sternoclavicular joint by locking the steel plate, thereby promoting the repair of the ligamentous joint capsule around the sternoclavicular joint and restoring the joint function. Background technique [0002] Fracture and dislocation of sternoclavicular joint is a common clinical disease, which sometimes causes serious consequences, such as dysphagia, hoarseness, pneumothorax, dyspnea, brachial plexus injury and related vascular symptoms, and long-term complications There are symptoms related to breathing difficulty, vascular compression, and brachial plexus compression, which can even lead to thoracic outlet syndrome, sepsis, and even death. [0003] At present, the internal fixation methods used for sternoclavicular joint dislocation include Kirschner wire fixation and steel wire fixation. Sin...

AI Technical Summary

Problems solved by technology

[0005] Sternoclavicular hook plate internal fixation needs to strip the retrosternal tissue, which has the risk of mediastinum and thoracic cavity injury; since the fixed axis of movement is in the sternal groove, which is inconsistent with the axis of movement of the sternoclavicular joint, there is a high risk of sternotomy in the later stage
