Abstract

The invention discloses a special absorbable suture line for a surgery. The special absorbable suture line for the surgery is mainly prepared from the following raw materials in part by mass: 9-14 parts of rhizoma imperatae, 7-10 parts of sanguisorba officinalis, 8-12 parts of cockscomb flowers, 5-9 parts of resina draconis, 4-8 parts of carbo of typhae pollen, 8-15 parts of dalbergia odorifera, 4-7 parts of crinis carbonisatus, 9-14 parts of capsella bursapastoris medic, 3-6 parts of marmor serpentinatum, 6-9 parts of plant soot, 7-11 parts of gallnut, 30-40 parts of polylactic acid, 20-30 parts of carboxymethyl chitosan, 2-6 parts of methacrylic acid, 1-4 parts of glycerinum and 3-5 parts of polyhexamethylene biguanidine hydrochloride. A product is good in antibacterial effect, wounds are healed quickly, and the special absorbable suture line is degradable, is not required to be taken out and is convenient to use.

Description

technical field [0001] The invention relates to the field of medical materials, in particular to a special absorbable suture for surgery and a preparation method. Background technique [0002] Medical surgical suture is a kind of wound healing, tissue ligation and tissue fixation, which plays an important role in the initial healing of wounds. Generally, it can be divided into two categories: absorbable sutures and non-absorbable sutures. Non-absorbable sutures do not degrade in the body. It is degraded by acid, alkali or enzyme. The degradation rate depends on the temperature, PH value of the tissue and the liquid environment around the suture. [0003] The Chinese patent document with publication number CN102406961A (application number 201110387194.1) discloses an absorbable surgical suture and a preparation method thereof, mainly involving chitosan surgical suture. The preparation process includes the steps of preparation of chitosan spinning solution, spinning and coag...
