Problems solved by technology

[0004] However, in the prior art, since the barb on the surgical suture is formed by cutting, the root of the surgical suture produces a cut mark after the barb cutting process, which causes the material to be easily torn at the cut mark, resulting in Breakage of the entire surgical suture

Abstract

The invention discloses an operative suture and a processing method thereof. The processing method of the operative suture comprises the following steps of cutting the preset length of the operative suture; obliquely cutting the operative suture to form a barb part through a cutter head of a barb machine; heating the cutter head to a softening temperature of the operative suture and staying the cutter head in the root portion of the barb part for the preset time; separating the cutter head and the operative suture and cooling the operative suture. According to the processing method of the operative suture, stress tear gaps at an incision stop point are avoided as secondary melting solidification is performed at the root portion of the barb part namely the incision stop point; meanwhile, the crystalline state is changed through local irradiation, the incision root portion of the barb part can generate crosslinking, the shear strength of the incision root portion is improved, and the purpose of avoiding incision tear failure is achieved.

Description

technical field [0001] The invention relates to the field of biopharmaceuticals, in particular to a surgical suture and a processing method thereof. Background technique [0002] In surgical operations, in order to reduce the harm to patients as much as possible, the requirements for the sutures used in the suture process are getting higher and higher. In order to meet the surgical requirements, more and more barbs are used. Surgical sutures formed by cutting barbs. [0003] The advantage of the barbed suture is that it can shorten the operation time, and the suture is firmly fixed, which can effectively prevent the tissue from slipping, and at the same time reduce the knots of traditional surgical sutures from falling off or breaking, and reduce the possibility of complications such as threading and infection in patients. [0004] However, in the prior art, since the barb on the surgical suture is formed by cutting, the root of the surgical suture produces a cut mark after...
