Abstract

The invention discloses a surgical suture doped with bioactive substances and a preparation method of the surgical suture, belonging to the technical field of surgical medicines. The surgical suture is prepared from the following raw materials in parts by weight: 80-120 parts of silk sericin, 20-30 parts of glucan, 3-8 parts of a canscora lucidissima extract, 4-6 parts of a peruvian groundcherry herb extract, 3-8 parts of a Japanese thistle herb extract, 3-8 parts of a scincidae extract, 5-10 parts of angelica pubescens extract, 2-5 parts of glycerin and 1-3 parts of bisabolol. The prepared surgical suture has good biosecurity, has no toxic or side effects and irritation and has the functions of rapidly stopping bleeding, resisting bacteria, diminishing inflammation, invigorating blood circulation, dispersing blood stasis, relievin internal heat or fever, promoting granulation and wound healing, preventing adhesion and the like; and furthermore, the prepared surgical suture has good blood compatibility and tissue compatibility, has no inflammatory response and human body exclusion, can be completely degraded and absorbed after a wound is healed, is relatively long in biodegradation time and suitable for suturing deep wounds.

Description

Technical field [0001] The invention belongs to the technical field of surgical medicine, and specifically relates to a surgical suture mixed with biologically active substances and a preparation method thereof. Background technique [0002] At present, absorbable sutures are commonly used in surgical sutures. Absorbable sutures mainly include catgut and synthetic fiber. Catgut is made from the submucosa of the small intestine of sheep. There are two types: ordinary and chrome. The absorption time of ordinary gut is shorter (4 to 5 days), and it is mostly used for ligation and skin suture. The chromium gut has a long absorption time (14-21) days and is used to suture deep tissues. Gut is a foreign protein, and the tissue reacts more severely during the absorption process. Therefore, when too much or too thick catgut is used, the wound inflammatory reaction is obvious. Its advantage is that it can be absorbed without foreign matter. In 2010, catgut was mainly used for suture...
