Description

Technical Field

[0002] Arthroscopic shoulder surgery, as a newly developed minimally invasive method, is an inevitable trend in the development of surgical methods in the future. The traditional method of shoulder arthroscopic surgery is to make 3-5 small 1 cm incisions on the anterior, lateral and posterior sides of the acromion, insert a tube-like working channel into each incision, and all subsequent operations are performed through these tubes. Arthroscopic shoulder suturing is one of the key techniques commonly used in shoulder arthroscopic surgery. There are two existing suturing methods: suturing the damaged rotator cuff with a suturing hook, including puncture, threading, threading, and knotting. The other method is to suturing the damaged rotator cuff with a rotator cuff suturing gun, including puncture, threading, and knotting.
