Description

technical field [0001] The invention belongs to the technical field of medical instruments, and relates to an acromioclavicular steel plate used for connecting the clavicle and the acromion in orthopedic surgery. Background technique [0002] After acromioclavicular joint dislocation or distal clavicle fracture, plate fixation is required. Such as figure 1 As shown, in the existing operation, the “Z”-shaped hook plate 01 is used for fixation, specifically, the main body 11 of the plate is fixed on the distal end of the clavicle 20 with screws, and the hook portion 12 of the plate is deep into the scapula. In the gap below the acromion 10. But because the acromioclavicular joint is an active part of the human body, the hook portion 12 of the hook plate 10 will cut the bone of the shoulder end 10 and the ligaments below it, which will cause pain and shoulder joint dysfunction in the patient's mild case, and may cause severe pain in the patient.
