Background
Labral injuries to the shoulder joint are a common disease, often caused by habitual dislocation of the shoulder joint. Most patients develop habitual dislocation after the first dislocation caused by movement or external force. Glenoid labial repair (Bankart repair) is the most common surgical procedure for anterior instability of the shoulder joint, but has a high risk of recurrent dislocation in patients with severe bone defects in the anterior margin of the shoulder. The coracoid shift Latarjet procedure provides a solution for this type of patient and achieves good results, particularly for young patients. With the development of open surgery characterized by 'large wound' to minimally invasive surgery characterized by 'small wound', exploring a new generation of minimally invasive surgical instruments facing natural orifices has become a necessary trend, and arthroscopic downlink Latarjet surgery gradually becomes a clinical hot point and difficulty. In the conventional procedure of the coracoid displacement Latarjet operation, the positioning of the cut coracoid is difficult, and since there is no special surgical instrument under an arthroscope for positioning or drilling the coracoid under an arthroscope, the open operation is required at present, the resulting incision largely affects the beauty, and the monitoring function under an arthroscope is lacked, and only the operation experience of the operator himself/herself is relied on, a special facility for the endoscopic cartilage transplantation is required, thereby reducing the trauma to the patient. The latarjet surgical instrument firstly needs to solve the problem of fixing the coracoid process under the arthroscope, and the coracoid process is difficult to fix at a proper position of the glenoid under the arthroscope due to various defects of the current coracoid process kirschner wire drilling positioner under the arthroscope. So, the final bone path position may be partially deviated and the final operation effect may be affected by the drilling of the bone path depending on the experience of the surgeon.
