Acromioclavicular joint belt cross-linking combined bionic steel plate

Abstract

The invention discloses an acromioclavicular joint belt cross-linking combined bionic steel plate. The steel plate comprises a clavicle end dissecting plate and an acromion end dissecting plate, boththe clavicle end dissecting plate and the acromion end dissecting plate are provided with a plurality of screw holes, a first fixing hole is formed in the side wall of the clavicle end dissecting plate, a second fixing hole is formed in the side wall of the acromion end dissecting plate, and the first and second fixing holes are welded through a medical steel cable. A fixing device has no influence on physiological function of acromioclavicular joint and shoulder joint, and has no secondary damage to surrounding tissues of the shoulder joint and the acromioclavicular joint during a steel plateimplantation fixing operation, so that it is ensured that a postoperative patient feels comfortable to a certain extent, and serious adverse reactions or complications, such as pain, joint stiffnessand internal fixator damage, cannot be generated.

Description

technical field [0001] The invention relates to the related technical field of medical equipment, in particular to a cross-linked composite bionic steel plate for acromioclavicular joint belt. Background technique [0002] Acromioclavicular joint dislocation accounts for a certain proportion of bone and joint injuries. For mild injuries, external fixation can be used to achieve healing, but for severe injuries (Ⅱ, Ⅲ) with serious injuries to related ligaments, the stability cannot be maintained, and surgical reduction and internal fixation are often required. The fixation of acromioclavicular joint dislocation is not as easy as that of fracture, mainly because the acromioclavicular joint is a movable joint with changeable directions of movement, and it needs to be fixed across joints after reduction. Due to the movement of the acromioclavicular joint, the steel plate was damaged, deformed and fractured, so rigid fixation was obviously impossible. Movable elastic fixation i...

AI Technical Summary

Problems solved by technology

The Gaizhuanli elastic fixing plate has a lack of rigidity, which is not conducive to the stability of the joint. If there is obvious fretting at the connection, the spring must be made very thin to reduce its rigidity and increase its elasticity, but the firmness of the connection is greatly improved. Reduced, significantly increased chance of injury

[0004] Patent 201520882530.3 discloses a three-dimensional anatomical micro-motion acromioclavicular plate. The patent connects two steel plates through a ball cage 8. Since the space inside the muscle itself is relatively small, it is difficult to install the ball cage 8.
