Description
Technical Field
The utility model relates to a medical instrument especially relates to a coracoclavicular ligament rebuilds positioner.
Background
The fixing treatment of acromioclavicular joint dislocation by adopting the loop steel plate is a minimally invasive technology, reconstructs coracoclavicular ligament by using the high-strength wire loop and the steel plate, resets and maintains the stability of the acromioclavicular joint, and is widely accepted in the field of orthopedics in recent years. The method has good effect on treating the fracture of the far end of the clavicle. The method is firstly completed under the condition of shoulder arthroscope operation, but the study curve is long, doctors without the operation experience under the condition of arthroscope are difficult to complete, and most domestic trauma orthopedists cannot operate and use the shoulder arthroscope, so that how to enable trauma doctors to master the fixing of the loop steel plate is one of the difficult problems of the treatment method. In the operation, the deviation of coracoid process and clavicle drilling positions and the cutting action of a steel plate loop cable can cause the problems of internal fixation, separation and the like, and the operation fails. A matched aiming and positioning device is arranged below the shoulder arthroscope to assist in completing positioning and manufacturing of a bone tunnel (Arthrex), and a trauma orthopedist does not have a special aiming and positioning device.
