Description

Rotator cuff stitching instrument used under shoulder arthroscope

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a rotator cuff stitching instrument used under a shoulder arthroscope.

Background

With the national body-building exercise and the aging of the national population, the number of patients with shoulder joint injury is increasing. The proportion of the patients with shoulder joint injury is higher than that of the patients with shoulder sleeve injury. The rotator cuff refers to four important muscle groups surrounding the humeral head to control the movement of the shoulder joint in all directions, including: supraspinatus, infraspinatus, subscapularis and teres minor. The shoulder joint is the joint with the greatest degree of freedom and flexibility of the human body, and plays a vital role in the movement of people no matter the sports (swimming, volleyball, basketball, javelin) which is highly required by athletes or the daily life (wearing and taking off clothes, washing, etc.) of common people. Long-term high-frequency shoulder joint movement can cause tiny or acute trauma to the rotator cuff, thereby seriously affecting the function of the shoulder joint. Among them, supraspinatus tendon injury is most common. Supraspinatus muscle is anatomically originated from the supraspinatus fossa of the scapula, ends at the upper part of the greater tuberosity of the humerus, and is innervated by suprascapular nerves, and functions as muscle contraction to drive the upper arm to abduct. Frequent anteflexion and uplift movements can cause the supraspinatus to tear and retract, resulting in abduction weakness of patients and serious influence on life.

For rotator cuff tear, the most prevalent treatment currently is arthroscopic rotator cuff suturing. In the operation, after a rotator cuff tear point is found under an arthroscope in a minimally invasive mode, a thread-provided anchor is placed on a bone bed attached to a rotator cuff, threads on the anchor are threaded into rotator cuff tissues through suture hooks at different angles by a thread threading technology, the rotator cuff is pulled back to an anatomical position, and knotting and fixing are carried out. Because the operation space in the shoulder joint is narrow, the soft tissues are numerous, and the operator has excellent hand feeling and experience, the operation difficulty is very high, and the learning curve is very long.

Therefore, the rotator-cuff stapler which is simple, practical and easy to master is designed.
