Problems solved by technology

Since the sternum is a cancellous bone, and the clavicle is located on the anterolateral side of the sternoclavicular joint, the commonly used Kirschner wire internal fixation and plate screws cannot be effectively fixed on the sternum, and postoperative reduction and fixation are very difficult. Dislocation occurs again after repeated repairs, causing more damage, prone to nonunion and malunion, local deformity, obvious pain, changes in the normal relationship of the sternoclavicular joint, and traumatic arthritis may occur over time. Axillary nerve compression due to too tight fixation, local dermatitis, ulceration, infection, long external fixation time, great pain for the patient, and great impact on daily life

Embodiment 1

[0012] Embodiment 1 As shown in Figures 1 and 2, a sternoclavicular hook plate for treating fracture and dislocation of the sternoclavicular joint is in a zigzag shape, one end of which is a hook-shaped structure 1 with a circular cross-section, and the other end is flat Structure 3, the flat structure 3 is slightly arc-shaped, and its curvature is adapted to the curvature of the front side of the proximal clavicle. L " shape, three to four screw holes 4 are arranged on the steel plate, are used for screw fixing.

Embodiment 2

[0013] Example 2 As shown in Figure 3, the above-mentioned sternoclavicular hook plate for the treatment of fracture and dislocation of the sternoclavicular joint has a screw hole directly at the front end of the hook, and cooperates with the screw 5 and the washer 6 to lock the hook on the sternum.

Embodiment 3

[0014] Example 3 As shown in Figure 4, the sternoclavicular hook plate for the treatment of fracture and dislocation of the sternoclavicular joint as described in Example 2 has a thin connecting rod 7 connected from the flat structure 3, with a hole at each end of the connecting rod 8. One of the holes is fixed with a screw to the screw hole at the front end of the hook, and the other hole corresponds to the screw hole on the flat steel plate, and is fixed on the clavicle by a screw to prevent posterior dislocation of the sternoclavicular joint.

[0015] Clinical application of the present invention

[0016] The operation of the present invention is performed under general anesthesia with air intubation or local anesthesia on one side of the cervical plexus. An "S"-shaped incision is made on the midline of the manubrium, from the sternoclavicular joint to the front edge of the clavicle, about 8 cm to 10 cm long, to expose the manubrium sternum, sternocleidoma The joint and the...

Abstract

A hooked steel plate for treating the bone fracture and luxation of sternoclavicular joint is a curved steel plate with a L-shaped hook at its one end and a flat arc structure and another end.

Description

technical field [0001] The invention belongs to the category of medical devices, in particular to a sternoclavicular hook steel plate for treating fracture and dislocation of the sternoclavicular joint. 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. Since the sternum is a cancellous bone, and the clavicle is located on the anterolateral side of the sternoclavicular joint, the commonly used Kirschner wire internal fixation and plate screws cannot be effectively fixed on the sternum, and postoperative reduction and fixation are very difficult. Dislocation occ...
