Endoscopic surgery was developed in the recent decades, it is a small revolution on the Open surgery that less tissue damage and much lower risk for the patient, and all surgeons loved it once available in his own filed. Barbed sutures is the idol sutures for Endoscopic surgery since the property of knotless, but the anchor of the thread from the suturing start is the key to success, V-Loc of Medtronic was developed that contains a closed-loop in tail to secure the anchor of suturing start point. The operation of V-Loc need the needle and thread across the loop-end to anchor the thread with tissue which need more practice, and this is the burden of surgeons’. Wegosutures developed the Stopper Designprovides the more convenient way to anchoring the sutures compare with V-loc. 
Vloc vs. Wegosutures Kontless
The Stopper of Wegosutures knotless sutures is a triangle Stopper in the end of the thread which no need complicate operation in the narrow space of Endoscopic surgery. This design applied on Violet PDO thread first and other materials later step by step. Surgeons who has experiences on Endoscopic surgery can use the thread by this design without long time training and practice on simulations. The absorption profile same with Wego PDO thread, available from USP 2/0 till 4/0. The safety of PDO sutures already approved by the market in the past 30 years. With the growing of endoscopic surgery, the knotless sutures will growing rapidly in the market. Another design on Endoscopic surgery sutures is the application of 5/8 circle needles, mostly by a fixed pathway in the instrument that the surgeon only need pull the trigger to suturing.
