Embodiment 1

[0040] Example 1 The sutures used in plastic surgery are mainly prepared from the following raw materials (10g each): 7 parts of box grass, 5 parts of Qingjiu vat root, 6 parts of baiji, 9 parts of buckwheat, 4 parts of Soushanhu, and 5 parts of Rhododendron 7 parts of astragalus, 8 parts of black trigonum, 6 parts of rusty nails, 45 parts of polylactic acid, 15 parts of chitosan, and 2 parts of polyglycolide. The preparation method of the used suture thread of above-mentioned plastic surgery is:

[0041] (1) Take the box grass and buckwheat, remove impurities and wash them, add 40% concentrated salt water that is 4 times the mass of raw materials, soak for 5 minutes, heat on high heat until boiling, take it out, put it in a frying pan, fry it dry with a slow fire, take it out and put it cold;

[0042] (2) Remove impurities from Qingjiu crock root, Soshanhu, Astragalus and rusty nails, soak in rice washing water for 10 minutes, take out and cut into thick slices, put them in...

Embodiment 2

[0047] Example 2 The sutures used in plastic surgery are mainly prepared from the following raw materials (10g each): 11 parts of box grass, 8 parts of green wine jar root, 12 parts of baiji, 13 parts of buckwheat, 9 parts of Soshan tiger, and 10 parts of rhododendron 12 parts of astragalus, 13 parts of black trigonum, 9 parts of rusty nails, 65 parts of polylactic acid, 25 parts of chitosan, and 8 parts of polyglycolide. The preparation method of the used suture thread of above-mentioned plastic surgery is:

[0048] (1) Take box grass and buckwheat, remove impurities and wash them, add 6 times the mass of raw materials in concentrated brine with a concentration of 40%, soak for 15 minutes, heat on high heat until boiling, take it out, put it in a frying pan, fry it dry with a slow fire, take it out and put it cold;

[0049] (2) Remove impurities from Qingjiu crock root, Soshanhu, Astragali and rusty nails, soak in rice washing water for 26 minutes, take out and cut into th...

Embodiment 3

[0055] Example 3 The sutures used in plastic surgery are mainly prepared from the following raw materials (10g each): 8 parts of box grass, 6 parts of green wine jar root, 8 parts of baiji, 10 parts of buckwheat, 5 parts of Soshan tiger, and 6 parts of rhododendron 9 parts of astragalus, 9 parts of black trigonum, 7 parts of rusty nails, 50 parts of polylactic acid, 18 parts of chitosan, and 4 parts of polyglycolide. The preparation method of the used suture thread of above-mentioned plastic surgery is:

[0056] (1) Take the box grass and buckwheat, remove impurities and wash them, add 40% concentrated salt water that is 4 times the mass of raw materials, soak for 8 minutes, heat on high heat until boiling, take it out, put it in a frying pan, fry it dry with a slow fire, take it out and put it cold;

[0057] (2) Remove impurities from Qingjiu crock root, Soshanhu, Astragalus and rusty nails, add rice washing water and soak for 14 minutes, take out and cut into thick slices...

Abstract

The invention discloses a suture thread used for plastic surgery. The suture thread is mainly prepared from, by mass, 7-11 parts of actinostemma tenerum var.tenerum, 5-8 parts of desmodium caudatum roots, 6-12 parts of rhizoma bletillae, 9-13 parts of buckwheat, 4-9 parts of roots of Chinese atropanthe, 5-10 parts of rhododendron mariae hance, 7-12 parts of astragalus membranaceus, 8-13 parts of sparganium stoloniferum (graebn.) buch, 6-9 parts of roots of hairy clovershrub, 45-65 parts of polylactic acid, 15-25 parts of chitosan and 2-8 parts of polyglycollide. The suture thread product prepared through the preparation method can make a wound heal quickly, tensile strength is high, scar generation can be reduced, and the suture thread is convenient to use.

Description

technical field [0001] The invention relates to the field of medical materials, in particular to a suture used in plastic 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 CN105079868A (application number 201510492433.8) discloses a kind of absorbable medical suture with good compatibility and its preparation method. The raw materials include: 20-40 parts by weight of polyglycolide, modified polylactic acid 10-20 parts, 50-70 parts of polylactic a...
