Problems solved by technology

Its disadvantages are: the process of weaving first and then coating is adopted, and the antibacterial coating is distributed on the outside of the braided thread instead of the core yarn and the braided yarn, so that it is easy to cause excessive antibacterial coating material at the weaving point of the suture thread Accumulation, the uniformity of antibacterial agent distribution on the suture surface is poor, affecting the antibacterial effect

Abstract

The invention provides a long-acting controlled-release antibacterial real silk woven type surgical suture and a preparing method thereof. The long-acting controlled-release antibacterial real silk woven type surgical suture is characterized by including heart yarn and weaving yarn that are woven, wherein the surfaces of the heart yarn and the weaving yarn are coated with antibacterial coatings; the antibacterial coatings contain macromolecular absorbing material and quinolone antibacterial drugs. As the weaving yarn contains antibacterial drugs, the long-acting controlled-release antibacterial real silk woven type surgical suture has the functions of sterilization and bacteriostasis; as the antibacterial drugs are uniformly dispersed in the macromolecular absorbing material, can be slowly released along with the swelling and degradation of the macromolecular absorbing material, so that the long-acting controlled-release antibacterial real silk woven type surgical suture has the long-acting controlled-release antibacterial effect.

Description

technical field [0001] The invention discloses a novel long-acting slow-release antibacterial silk braided medical suture and a preparation method thereof. Background technique [0002] Silk braided sutures are cheap, harmless to the human body, and can provide the amino acids needed by the human body. Therefore, they are widely used as suture materials in modern surgical operations, especially in epidermal suture, small blood vessel ligation, and anastomosis of hollow organs. There are many applications. The current silk suture adopts a braided structure, that is, it is woven on a spindle-type braiding machine, and the bobbin placed on the spindle is driven by the spindle to move. All the bobbins are divided into two groups, and the two groups of bobbins move in opposite directions. , when the spindles meet each other, the yarns on the bobbins moving in opposite directions will also interlace each other, thus forming an interlaced weaving structure. Because the twist dire...
