Abstract

Abstract: In order to solve the problem of excessive tension of carbon fiber suture in the thread path, the thread tension of double-sided suture device was analyzed. Catenary model, thread and tension adjuster, thread taking-up hole and thread ring tension model were established based on the thread path of double-sided suture device. The tension variation during suture was analyzed, and the structure size was optimized by constrained random direction method for the thread taking-up mechanism, and the suture experiment was carried out for the optimized two-sided suture device. The experimental results show that the tension of the overpass suture of the double-sided carbon fabric suture device is reduced by 58% under the optimized taking-up mechanism, which solves the problem of more hair caused by excessive tension in the overpass suture, improves the quality of the stitches, and provides a basis for ensuring the stability of the tension of the stitches.
