Belt carrier double-hook screw for treating acromioclavicular joint dislocation

Abstract

The invention discloses a belt carrier double-hook screw for treating acromioclavicular joint dislocation. The belt carrier double-hook screw comprises a U-shaped screw sheath and fixing carriers, an inner screw is arranged in the U-shaped screw sheath, the side walls on the two sides of the screw sheath are arc surfaces, smooth grooves are formed in the arc surfaces, hooks are arranged at the top ends of the two side walls of the screw sheath respectively, holes are formed in the tops close to the two side walls of the screw sheath and the bottom of the screw sheath respectively, and the fixing carriers are arranged in the grooves and penetrate through the holes to be fixed on the hooks. The belt carrier double-hook screw for treating the acromioclavicular joint dislocation solves the problems that in the prior art, unfirm fixing and joint micro movement loss can happen to acromioclavicular joint fixing, so that the operation fails or complications are caused. Through the double fixation of the inner screw and hook sharps of the screw sheath, stability and firmness are achieved while elastic fixing is achieved, the acromioclavicular joint does not need to be exposed, an acromioclavicular structure is not damaged, the operation technique is simple, consumed time is little, the acromioclavicular joint is promoted to be healed maximally, and postoperative recovery is fast.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a double-hook screw with loops for treating acromioclavicular joint dislocation. Background technique [0002] Dislocation of the acromioclavicular joint is a common injury, especially in athletes and traffic accidents, but most orthopedic surgeons do not pay enough attention to it. For patients with obvious dislocation without surgery, symptoms such as shoulder pain, limited mobility, and shoulder deformity are often secondary. The dislocation of the acromioclavicular joint accounts for about 3.2% of the joint dislocations in the whole body, and 12% of the shoulder injuries. Most of them are caused by violence on the acromioclavicular joints, which causes some or all of the acromioclavicular joints to lose their normal alignment. For the repair, fixation and reconstruction of the acromioclavicular joint, there are currently several methods: [0003] Kirschn...
