Detailed Description

As shown in fig. 1 to 4, a thread withdrawal prevention knotting-free suture comprises a first suture needle 1, a second suture needle 2 and a suture body at two ends, wherein the first suture needle 1 and the second suture needle 2 are respectively connected at the two ends of the suture body, the suture body comprises a suture barb section 6 and an anchoring barb section 7, a middle connection area of the suture barb section 6 and the anchoring barb section 7 is set as a third barb-free section 4, a connection area between the suture barb section 6 and the first suture needle 1 is set as a first barb-free section 3, a connection area between the anchoring barb section 7 and the second suture needle 2 is set as a second barb-free section 5, the length of the suture barb section 6 is greater than that of the anchoring barb section 7, the angles of barbs on the suture barb section 6 and the anchoring barb section 7 are opposite, and a continuous and stable anchoring force can be provided after the suture is embedded into tissue, preventing the suture from backing out or slipping or deflecting.

Specifically, the length of the suture barb section 6 is not more than 5m, the length of the anchoring barb section 7 is 1-5 cm, the lengths of the first barb-free section 3, the second barb-free section 5 and the third barb-free section 4 are 0.5-3 cm, preferably 1 cm-1.5 cm, and the lengths of the first barb-free section 3 and the second barb-free section 5 are the same. The length is designed to ensure that the section is firstly sewed on one side of the wound in the operation process, and the whole wound is sewed in the opposite direction by the first sewing needle 1 at the other end after the second sewing needle 2 sews 2-3 needles, so that the operation process is smoother, the operation difficulty is reduced, and the pulling and the secondary injury to the wound are reduced.

Specifically, barbs on the surfaces of the suture lines of the suture barb section 6 and the anchoring barb section 7 are distributed spirally, and the number of the barbs in one spiral group is 5-25, preferably 8-15; the number of barbs in each centimeter of length of the suture body is 5-20, and 8-15 is preferable. The cutting depth H of the barb is 1/4-1/3 of the suture diameter, preferably 1/4-1/3; the cutting angle Q is 20-80 degrees, preferably 30-60 degrees. The specification of the wire diameter of the suture body is 2#, 1#, 0#, 2-0#, 3-0#, 4-0#, 5-0# and the like, and is the same as the common specification.

The material of stylolite body is PDO, polypropylene, silk or poly carplon, first seam needle 1 adopts the seam needle that 302 stainless steel, 304 stainless steel made or the black needle after surface treatment, second seam needle 2 adopts black needle. Specifically, the first sewing needle 1 and the second sewing needle 2 adopt a curved needle structure, can sew human tissues, and can enable the sewed wound surface to be small. Meanwhile, the selection of the second sewing needle 2, namely a black needle, can visually distinguish the sewing barb section from the anchoring barb section; during sewing, 2-5 needles are sewed by the anchoring barb section provided with the black needle, then the black needle is cut off, and then the first sewing needle of the anchoring barb section is used for continuously sewing.
