Anatomical sternoclavicular joint bone fracture plate and fixation system in sternoclavicular joint

Abstract

The invention provides an anatomical sternoclavicular joint bone fracture plate and a fixation system in sternoclavicular joint. The anatomical sternoclavicular joint bone fracture plate comprises a bone fracture plate body, the bone fracture plate body comprises a near end and a far end, the near end of the bone fracture plate body is attached to the clavicle part of a sternoclavicular joint, a movable hole is formed in the near end of the bone fracture plate body, the inner wall of the movable hole is a smooth surface, a gap exists between the inner wall of the movable hole and a screw penetrating into the movable hole, the central axis of the movable hole passes through the sternoclavicular joint, and a plurality of locking holes are formed in the far end of the bone fracture plate body. The fixation system in the sternoclavicular joint comprises the anatomical sternoclavicular joint bone fracture plate and cancellous bone screws matched with the movable holes of the bone fracture plate body. According to the anatomical sternoclavicular joint bone fracture plate, the stability of a dislocated sternoclavicular joint can be effectively guaranteed, repairing and healing of surrounding ligaments are accelerated, a patient can do early exercise, and the joint function can be recovered earlier.

Description

technical field [0001] The invention relates to the field of medical devices, and more specifically relates to an anatomical sternoclavicular joint bone plate and a sternoclavicular joint internal fixation system. 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. Since the sternum is cancellous bone and the clavicle is located on the anterolateral side of the sternoclavicular joint, Kirschner wire internal fixat...

AI Technical Summary

Problems solved by technology

[0003] At present, the internal fixation methods used for sternoclavicular joint dislocation include Kirschner wire fixation and steel wire fixation. Since the sternum is cancellous bone and the clavicle is located on the anterolateral side of the sternoclavicular joint, Kirschner wire internal fixation cannot be effectively achieved on the sternum. It is very difficult to stabilize and fix postoperatively, and dislocation often occurs again due to weak fixation

The Kirschner wire moves into the thoracic cavity, causing more damage, long external fixation time, great pain for the patient, and great impact on daily life

The clavicular hook plate used for acromioclavicular joint dislocation in the prior art is poorly matched, poorly stable, and does not conform to the physiological movement characteristics of the joint; the steel wire fixation is prone to fracture and failure
