Absorbable sutures are divided into collagen lines and chemically synthesized lines. The collagen line has a gut (made from a healthy animal's intestine), a collagen fiber absorbs the suture (takes high collagen from the animal's tendon), and chitin and chitosan absorb the suture (taken from the shrimp and crab) In the shell). The main collagen line produced by Haidike in Shandong is the gut line. The chemical synthesis lines are PGA, PGLA, PDO, and PGCL, and are polymer absorbable linear materials made by chemical techniques.

According to the needs of medical development, the ideal absorbable suture should meet the following conditions:

1. Tensile strength: The minimum strength that can break a single suture. The tensile strength refers to a specific tensile value, and the nonlinear interval. Effective tensile strength refers to the tensile strength of the stitch after looping or knotting.

2. The diameter of the suture: the selection principle of the thickness of the absorbable suture is to select the smallest possible suture under the condition of being able to withstand the tension of the wound.

3. The structure of the suture: the structure of the absorbable suture refers to the single or multi-strand weaving of the suture. Multi-strand sutures are woven. Multiple absorbent sutures are easy to handle but increase the chances of infection and tissue response. It is easy to cause infection because siphoning causes bacteria and foreign matter to infiltrate. The bacteria are hidden inside the braided wire to escape the phagocytosis of phage cells. Therefore, a single strand of absorbable suture is more suitable for suturing contaminated wounds. With the development of medicine, the probability of infection of multiple absorbable sutures is also very small.

4. Friction coefficient: In order to ensure that the absorbable suture is easy to operate during suturing and knotting, the holding coefficient with high friction coefficient is good. For the low friction coefficient, the suture is easy to slide over the tissue, and the knot is easy to fall off. Play a few more knots.

5. A certain mechanical properties: absorbable suture has appropriate mechanical strength, a certain degree of elongation, flexibility and elasticity, a certain degree of wet strength and friction coefficient.

6. Biological properties: Sterile, with good blood compatibility and histocompatibility, no inflammatory reaction, complete degradation and absorption after wound healing and degradation products are safe and harmless to human body. Ideal absorbable sutures should not impart dents, nicks, blood clots, and bacterial adhesion to the wound being healed.

Shanxian Haidike Biotechnology Co., Ltd. specializes in the production of absorbable sutures. The line body is made of soft and tough absorbable wire. The needle body is imported from Korea with high quality stainless steel needle. The tail of the electrolytic treatment is connected with the wire body, which is smooth and smooth. Suture damage to tissue during small sutures.
