Problems solved by technology

Once this happens, due to the fibrous nature of the suture material, the barbs can peel away from the shaft along the effective length of the suture leading to catastrophic failure

Abstract

The invention provides a surgical suture with reinforced barbs. The surgical suture comprises a slender body, wherein the slender body is a single-stranded suture with a smooth outer surface; at leastone barb is arranged on the slender single-stranded suture; the barbs are arrayed in one direction or double directions and can be positioned on the single side or the symmetric double sides of the slender single-stranded suture; and the barbs which are positioned on the symmetric double sides can be positioned at the same position or different positions of the slender single-stranded suture. Atleast one annular groove is formed in the lower edge of each barb, a biological adhesion agent coats the inside of each groove; at least one circle of suture is wound in each groove; after winding ofthe suture is finished, each groove is filled with a filling agent completely and smoothly. By the surgical suture with the reinforced barbs, the fixing strength of the single-stranded suture barbs can be improved effectively, the barbs are prevented from failing or being stripped from an axle of the suture, and the risk of failing of a clinical suture surgery is relieved.

Description

technical field [0001] The invention relates to the surgical suture technology in the field of biomedical materials, in particular to a surgical suture with reinforced barbs. Background technique [0002] Medical surgical suture is a kind of sterile thread used for wound healing, tissue ligation and tissue fixation, and plays an important role in the initial healing of wounds. In clinical operations, one end of the suture is tied to a suture needle, and the needle passes through the wound tissue to tie the suture into multiple loops to keep the tissue together. Known surgical sutures include monofilament sutures and multi-strand sutures. Single-strand sutures are made from a single fiber that passes through tissue with less resistance and prevents bacteria from adhering to them. Single-strand suture needs to be tied with one or more knots to secure the binding force of the suture. Once the knot slips off, the tissue may crack; if the knot is not tied tightly, a gap may for...
