Problems solved by technology

[0004] At present, the surgical sutures used in domestic hospitals are mainly catgut and chemical synthetic sutures, which are easy to affect the absorption process due to individual differences in patients, and the absorption effect is not ideal, and even non-absorption occurs. The pain of the patient; in addition, there are disadvantages of poor biocompatibility, stimulating the inflammatory response of the incision, affecting the healing quality of the incision, and producing scars

Abstract

The invention discloses a surgical operation suture and a preparation method thereof. The surgical operation suture is prepared from 58-70 parts by weight of collagen, 30-50 parts by weight of chitosan, 6-10 parts by weight of rose mallow root, 5-8 parts by weight of root of Millettiapulchra Kurz var.typica f.Laxior Dunn, 4-9 parts by weight of nakedflower beautyberry branchlet and leaf, 6-10 parts by weight of Grewia lantsangensis Hu, 8-12 parts by weight of peruvian groundcherry herb, 6-11 parts by weight of szechuan melandium root, 4-7 parts by weight of Scutellaria indica, 8-13 parts by weight of stephania sinica diels, 9-14 parts by weight of henry clematis root, 3-7 parts by weight of Angelica dahurica, a proper amount of glycerin and a proper amount of azone. The surgical operation suture has good bio-safety, no toxic or side effect, no irritation, effects of fast stopping bleeding, relieving swelling and pain, resisting bacterium and diminishing inflammation, activating blood circulation and dispersing blood stasis, removing toxins and engendering flesh, and promoting wound heal and preventing adhesion, has good blood compatibility and histocompatibility, no inflammation and no human body rejection reaction, and can be completely degraded and absorbed after wound heal. The degraded product is safe and nontoxic for the human body, can prevent infection, can promote wound heal and does not produce scar.

Description

technical field [0001] The invention relates to the field of medical materials, in particular to a surgical suture and a preparation method thereof. Background technique [0002] Surgical sutures refer to special threads used for ligation and hemostasis, suture hemostasis and tissue suture in surgical operations or trauma treatment. Generally, it can be divided into two categories: absorbable thread and non-absorbable thread. Absorbable sutures are divided into different types according to the material and degree of absorption: catgut, chemically synthesized sutures (PGA), and pure natural collagen sutures. 1. Sheep catgut: It is made from healthy animal sheep intestines and sheep, and contains collagen components, 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 tissu...
