Background
Most surgical sutures have smooth surfaces, and the wounds of biological tissues can be sutured and fixed only by knotting after surgical suturing, so that the surgical time is prolonged, and the surgical risk is increased; also has the problems that the suture can not be absorbed and degraded by body tissues and has large biological rejection and the like
In recent years, more and more knotting-free sutures have appeared on the market, such as barb-type sutures, which have a barb structure that can increase the anchoring effect of the suture on wound tissue during wound closure, avoid knotting, and reduce the operation time. For the barb type suture disclosed in CN201711054602.5, the lower edge of the barb is provided with an annular groove, and a ring of suture is adhered in the groove by biological adhesive, so that the mechanical property of the whole suture is reduced, and the biocompatibility is reduced due to the existence of the biological adhesive. CN201810138240.6 discloses a degradable suture with barbs, but its biocompatibility is small, the fastness of barbs is not high, the strength of barbs is not high, and it is easy to fall off. CN 101401735A, CN 101518457a discloses a barb type medical device, in which the barb is integrally formed with a linear workpiece, and the anchorage is not strong. CN 206745401U discloses a surgical suture, comprising a suture body and a barb member, wherein the barb member comprises a fixing part for fixing the barb member on the suture body, a ring-shaped part connected with the fixing part and a tissue engaging protrusion arranged on the ring-shaped part.
The development of the barb type silk suture line which has biocompatibility, high barb firmness and difficult shedding is necessary.

Further, the silk suture thread is a woven silk suture thread.
Furthermore, the material of the combining part (3) is silk fibroin.
Furthermore, the barbs are distributed on the surface of the wire body (1) in a surrounding mode at intervals.
Furthermore, the diameter of the silk suture is 0.05 mm-2 mm.
Further, the barb part (2) is composed of crystalline silk fibroin, and the aggregate structure thereof is mainly composed of a fibroin II crystal structure. The barb portion (2) of silk fibroin material can be in the same place with the fine combination of line body (1), has the same biocompatibility simultaneously, and silk fibroin II crystal structure can make the barb obtain more rigid structure, sews up to the tissue and has better anchoring effect.
Borrow by above-mentioned scheme, the utility model discloses at least, have following advantage:
1. the barb type silk suture line of the utility model is provided with a plurality of barbs, and the barb type silk suture line does not need assistant to sew in the surgical suture process; the suture time is short, and the wound can be automatically closed without knotting after the suture is finished; after the suture is finished, the tension of the wound is uniformly distributed, the pain is not caused, and a large scar is not generated after the wound is healed.
2. The utility model discloses a barb type silk stylolite biocompatibility is good, can not cause the stimulation and the immunoreaction of wound, can adsorb cell growth factor, promotes tissue healing.
3. The utility model discloses the superior performance that has not only kept the silk stylolite has still addd rigid barb structure, and silk stylolite mechanical properties is better moreover, is difficult to the fracture.
The above description is only an overview of the technical solution of the present invention, and in order to make the technical means of the present invention clearer and can be implemented according to the content of the description, the following detailed description is made with reference to the preferred embodiments of the present invention and accompanying drawings.
