During arthroscopic surgery, the anchor suture is easy to tangleunable to fix the soft tissue using conventional one lumen cannula. Thus we design a novel “Double lumen cannula” containing a flexible septum inside the cannula which can separatechange the cannula volume dynamically into two lumen. This would decrease the surgical timesoft tissue injury,improve the security of su

The Augmented patch system for rotator cuff surgery is used in situations where soft tissue is detached from the tissue, such as tendon rupture. Through this system, arthroscopic minimally invasive surgery can greatly shorten the operation timeimprove the efficiency of the operation. Large goat animal experiments have been plannedexecuted together with NAR Labs Animal Center. Compared with the traditional surgical method, the recovery strength of the sheep＇s tendon using the thin Augmented patch system has increased by 72, which is a significant improvement
