The invention relates to a surgical suture auxiliary device and a manufacturing method thereof.

Surgical suture is a medical device used to suture human tissues after injury or surgery. It is generally composed of a needle attached with a certain length of filament. In thousands of years of history, sutures of different shapes, sizes and materials have been developed.

Surgery itself is a highly specialized subject, and the quality of surgery depends on the experience of the physician. The suture of the operation and the anastomosis of the lumen (digestive tract, urinary tract and blood vessel) are more dependent on the judgment of the surgeon. Therefore, it is even more difficult to make a symmetrical and complete anastomosis.

Traditionally, in the process of surgical operation, it is difficult to find the needle insertion position of the suture thread because the position of the wound is often very subtle, and the doctor’s experience is often needed to stabilize the fixed position of the needle thread during the suture process, so as to avoid the needle thread irregularities. The symmetry and bending conditions cause the doctor to concentrate on the suture process, which consumes energy and energy.
