After detailed investigation for the requirement of surgeons and identify the critical point of successful surgery, we developed special structure with industrial leading braiding machine supplier together, that offer the market a smooth, soft and strong PGA thread. Braided thread can be treated as two parts: twist core and knitting wall, consist by the bundle of fibers. The size of bundle in our PGA is larger than competitor’s base on precisely extruded fibers. The bigger size bundle makes the same size diameter thread with less bundles and a smaller twisted core, and this leads a softer property. Also makes the knot security higher since the less bundle structure make the thread easier flatted than smaller bundle while knotting. Some competitor make their thread little flat to increase the security of knot, but this will increase the loss and failure rate of needle crimping process as the needle hole drilled in round hole. Our design make a perfect balance. The lager bundle knitted wall is much thicker than the competitor, this brings higher safety while facing the jag of needle holders and forceps. And over 80% knots was made by instruments like needle holders and forceps, this design really helps to increase the successful rate of surgery. Minors change brings better performance after long time research and development. A lot of surgeons report that they can feel the knotting security better and stronger that most competitors, especially the soft thread, it brings better handle-performance that makes surgeons more easy.
