Problems solved by technology

[0004] At present, the use of medical absorbable sutures is mainly catgut and chemically synthesized sutures, which are easy to affect the absorption process due to individual differences in patients, and the absorption effect is not ideal, and even the phenomenon of non-absorption occurs, which has the disadvantage of rejection. Increased patient pain; existing absorbable sutures have low tensile strength and poor biocompatibility
At present, the function of the existing suture is relatively single, and it cannot meet the various needs of medical use at the same time.

Abstract

The invention discloses a medicinal absorbable suture and a preparation method thereof. The medicinal absorbable suture has the good functions of stopping bleeding and pains, restraining bacteria and promoting wound healing. The medicinal absorbable suture is mainly prepared from, by weight, 20-32 parts of PHB, 55-74 parts of carboxymethyl chitosan, 5-9 parts of eclipta prostrate, 3-6 parts of cuttlebones, 8-12 parts of cyrtomium fortunei, 7-10 parts of white peony roots, 5-10 parts of dried alums, 4-8 parts of pomegranate peels, 3-5 parts of hairyvein agrimony, 6-10 parts of desertliving cistanche, 4-9 parts of mangnolia officinalis, 3-6 parts of eucommia ulmoides, 4-10 parts of ovate leaf holly bark, 6-11 parts of bodinier's beauty-berries, 3-7 parts of taxillus chinensis and an appropriate amount of glycerin. The obtained product is safe to use, free of toxic and side effects and stimulation and appropriate in strength and flexibility, the surface friction coefficient is small, suturing and knotting are easy, and the suture has good biodegradability, can be completely absorbed by bodies, has no obvious individual difference, has good biocompatibility, and can shorten treatment time, avoid wound infection and promote wound healing.

Description

technical field [0001] The invention belongs to the field of medical materials, and in particular relates to a medical absorbable suture and its preparation method. Background technique [0002] Medical suture is a common thread material, which is widely used in various surgical operations to suture wounds and connect tissues. Absorbable suture: In surgical suture, after being implanted in human tissue, it can be degraded and absorbed by the human body, and it does not need to be removed, but it is a new type of suture material that avoids the pain of removing the stitches. According to the absorbability of the suture material, it can be divided into catgut, chemically synthesized polymer thread, and pure natural collagen suture. Requirements for medical sutures: 1. It can maintain sufficient strength during wound healing, and should be able to stretch to adapt to wound edema, and retract to its original length as the wound retracts. 2. After the wound is healed, it can be...
