Abstract

The invention discloses a medical surgical suture. The surgical suture is mainly prepared from, by weight, 48-62 parts of chitosan, 30-40 parts of silk protein, 4-7 parts of tangerine leaves, 3-6 parts of woundwort, 5-8 parts of short hairy antenoron, 7-11 parts of Chineses trichosanthes roots, 5-9 parts of lindera angustifolia cheng, 3-7 parts of hairyvein agrimony, 6-10 parts of ficus tikoua, 8-12 parts of japan clover herbs, 4-8 parts of rhizoma bletillae and 5-9 parts of Chinese umbrellaleaf rhizomes and roots. The medical surgical suture further has the advantages that healing of a wound can be promoted, ulcer resistance is achieved, the defect that chitosan medical fibers are quick in tensile rigidity loss in the in-vivo environment and other defects can be remedied, a tissue reaction is avoided, safety and effectiveness are achieved, and no toxic or side effect exists.

Description

technical field [0001] The invention relates to the field of medical materials, in particular to a medical surgical suture and a preparation method thereof. Background technique [0002] Medical surgical suture refers to a special thread used for wound ligation, suture hemostasis and tissue suture in surgical operations. According to its biodegradability, it can be divided into two categories: non-absorbable thread and absorbable thread. An ideal suture should be stable in vivo, have little tissue reaction, be difficult to loosen after knotting, and the suture itself will not fray or split. Absorbable sutures are non-toxic, compatible with human tissue and blood, and can be degraded. The first bioabsorbable suture material used was catgut, which is pure collagen fibers obtained from sheep intestinal mucosa or bovine intestinal mucosa after removing impurities. The fiber has excellent smoothness and good stability at nodular sites, but its disadvantages are uneven composit...
