Abstract

The invention discloses an anti-bacterial operation suture line and a method for preparing the same. The anti-bacterial operation suture line is mainly prepared from, by mass parts, 25-45 parts of polypropylene resin, 2-14 parts of polyglycolide, 6-20 parts of polylactide, 4-16 parts of poly glycolide-co-lactide, 8-20 parts of triclosan and 35-55 parts of double distilled water. Compared with the prior art, the anti-bacterial operation suture line has the advantages that the anti-bacterial operation suture line is good in anti-bacterial effect and can effectively prevent operative wound infection; and the tension maintenance time of the anti-bacterial operation suture line is long, and complete healing of operation wounds can be guaranteed.

Description

technical field [0001] The invention relates to the field of medical biomaterials, in particular to an antibacterial surgical suture and a preparation method thereof. Background technique [0002] Surgical sutures refer to special threads used for suturing hemostasis and tissue suturing in surgical operations or in trauma treatment. Generally, it can be divided into two categories: absorbable thread and non-absorbable thread: antibacterial surgical suture can be divided into catgut, chemical synthetic thread, and pure natural collagen suture according to the material and degree of absorption. [0003] Sheep catgut is made from healthy animal sheep intestines and contains collagen, so there is no need to remove the sutures after suturing. There are two types of medical gut: common gut and chrome gut, both of which can be absorbed. The length of time required for absorption depends on the thickness of the gut and the condition of the tissue. Generally, it can be absorbed wit...
