Shoulder joint dislocation repairing system

Abstract

The invention relates to a shoulder dislocation repairing system, and the system comprises a working channel device for delivering a graft bone block from the front side of a shoulder joint, a guide device for establishing a glenoid bone tunnel from back to front and a fixing device for fixing the graft bone block in front of a glenoid. According to the shoulder joint dislocation repairing system, the number of surgical tools is reduced, the structural design of the surgical tools is optimized, and therefore the surgical process is optimized, and the surgical efficiency is improved; according to the shoulder dislocation repairing system, the operation mode that glenoid marrow is established through a rear side approach can be adopted, dense areas of arteries, veins, nervous systems and lymphatic systems on the front side of the shoulder joint are avoided, wounds are small, damage to the human body is small, the requirement for doctors is low, the operation risk is small, and the popularization is easy; related complications caused by screw fixation can be avoided by adopting a suture steel plate pressurizing and fixing mode; the bone taking part is changed into the ilium, the original physiological structure of the human body is not changed, and unknown risks cannot be generated.

Description

technical field [0001] The invention relates to the technical field of shoulder joint repair, in particular to a shoulder joint dislocation repair system. Background technique [0002] The shoulder joint is the joint with the largest range of motion in the whole body joints of the human body, and its dislocation accounts for more than 40% of the joint dislocations of the whole body, of which the anterior dislocation accounts for the vast majority. As the frequency of anterior shoulder dislocation increases, injuries to the anterior inferior labrum of the glenoid are often accompanied by bone defects of varying degrees. At present, the mainstream treatment method for recurrent shoulder dislocation is the anterior approach. The coracoid process of the scapula is cut and transplanted to the bone defect and fixed with screws to achieve the purpose of repairing the bone defect and treating the dislocation.

AI Technical Summary

Problems solved by technology

[0003] Conventional shoulder joint glenoid bone graft device combination adopts the anterior approach for treatment, which has obvious disadvantages

For example: (1) The front side of the shoulder joint is a dense area of ​​arteries, veins, nervous system, and lymphatic system, and the risk of surgery on the front side is relatively high; the coracoid process is connected to the coracoid process, and the intercepted coracoid process is not separated from the coracoid process , the original physiological structure of the human body is changed after transplantation, and the risk is unknown; the intercepted coracoid process needs to be polished and cut before it can be used for transplantation. This process is easy to cause damage to the coracoid-acromial ligament and the human body; The damage is relatively large; the anterior approach has high requirements on the operator's operating level and proficiency, and the operating threshold is relatively high; (2) the repair device contains many tools and is difficult to operate. The field of view that can be observed in the medium is small and unclear, and it is easy to damage human tissues such as nerves, arteries, and veins during the channel expansion process. After the working channel is expanded, specific equipment is required to fix the working channel tube, otherwise the working channel tube is prone to displacement; The process resistance of each part of the channeler is relatively large, and there is a certain degree of difficulty in advancing; (3) The guide tool in the prosthetic device has a large structural design and takes up a large space. The operation is inconvenient and the fixation effect is not good. There are many steps in the process of fixing the guide on the bone of the shoulder joint, which reduces the operation efficiency. ) Fixing the coracoid on the worn shoulder joint with screws is a difficult and complicated operation, and it is prone to complications such as postoperative reduction failure and shoulder joint pain.
