Abstract

The invention discloses a medical suture mainly prepared from the following raw materials in parts by mass: 6-15 parts of rhizoma picrorhizae, 2-6 parts of caulis trachelospermi, 12-17 parts of zygophyllum fabago l., 3-9 parts of root of featherycleft horsegentian, 6-12 parts of calogyne pilosa, 5-12 parts of silvery aleuritopteris, 12-18 parts of common fibraurea stem, 6-15 parts of root of delavay habenaria, 2-6 parts of herb of marginate rockbell, 40-48 parts of poly-L-lactic acid, and 10-16 parts of silk fibroin. The medical suture is safe, has no stimulation, can be completely biologically degraded, promotes tissue growth, helps wounds heal, and is good in mechanical properties, good in tensile strength and easy to tie.

Description

technical field [0001] The invention relates to the field of medical supplies, in particular to a medical suture and a preparation method. Background technique [0002] Surgical sutures are commonly used biological textiles, which are widely used in various surgical operations to suture wounds and connect tissues, and are extremely important medical materials. With the development of biomedicine and polymer material science, biodegradable medical materials are attracting more and more attention. In the field of medicine and health, biodegradable medical materials have been vigorously developed, and are widely used in the fields of sutures in the body, "human tissue engineering" materials, drug release carriers, bone-setting materials for surgery, etc., especially in the shape repair of tendons and ligaments It has broad application prospects in functional reconstruction. Polylactic acid (PLA) uses corn, cassava and other crops as raw materials. It is fermented and extracte...
