Embodiment 1

[0041] Example 1 A biodegradable medical suture was prepared from the following main raw materials, all in parts by weight (35g / part): 7 parts of sedum; 10 parts of ascites; 9 parts of old snails; 6 parts of sweet potato root; 4 parts of passionflower; 3 parts of lychee kernels; 12 parts of Drynaria fortunei; 6 parts of Bauhinia; 10 parts of flowers and plants; 28 parts of polylactic acid; 14 parts of silk fibroin.

[0042] The preparation method of the degradable medical suture is:

[0043] (1) Mix sedum and ascites, add Shaoxing rice wine 1.0 times the amount of the raw material, decoc on a slow fire for 20 minutes, filter, and use the filtrate for later use;

[0044] (2) Add lychee kernels, sweet potato roots, Bauhinia and Rhizoma tonic to the above-mentioned filtrate, mix well, let stuffed for 10 minutes, put in a steamer, cook until the filtrate is exhausted, take it out and set aside;

[0045] (3) Put the raw materials processed in step (2) together with old snails, passionflowe...

Abstract

The invention discloses a degradable medical suture line which is prepared by the following main raw materials in parts by weight: 7-10 parts of red-spotted stonecrop, 10-13 parts of veronicastrum herb, 9-11 parts of black medic herb, 6-9 parts of digua fig root, 4-7 parts of passiflora edulis, 3-7 parts of semen litchi, 12-15 parts of drynaria rhizome, 6-9 parts of bauhinia purpurea, 10-13 parts of thunbergia fragrans, 28-40 parts of polylactic acid and 14-17 parts of silk fibroin. The degradable medical suture line disclosed by the invention has the benefits that all the raw materials can be biologically degraded and completely absorbed in a human body and are free from stimulation on tissues and toxic and side effects; the suture line can effectively promote wound healing, has no apparent stitch trace after wound healing and can satisfy the clinical demands.

Description

Technical field [0001] The invention relates to the field of medical materials, in particular to a degradable medical suture thread and a preparation method. Background technique [0002] Surgical suture is a sterile thread used for wound closure, tissue ligation and fixation. Non-biodegradable sutures cannot be absorbed by the body and have different levels of tissue reactions. Suture epidermis, especially facial skin, will leave scars; while biodegradable sutures are easily absorbed or excreted after being degraded in body tissues, avoiding two The pain caused by the second operation reduces the chance of infection of the wound and the scar is small. Therefore, biodegradable medical sutures have attracted more and more attention. [0003] Generally speaking, the ideal degradable suture thread should have the following basic requirements: it can be thoroughly disinfected and sterilized; it has certain mechanical properties (such as appropriate mechanical strength and elongation,...
