Problems solved by technology

However, the main component of this material is high-molecular synthetic polypropylene, which has a high content and cannot be absorbed by human tissue, nor can it fall off naturally after suturing the skin. It is still necessary to remove the stitches for suturing the skin.

Embodiment 1

[0006] Embodiment one. Take 8-12g of collagen extracted from the tendon, 4-6g of chitin, and 2-3g of polyacrylamide hydrophilic hydrogel, a synthetic polymer material, and mix them with 1000ml of 0.9% sodium chloride injection. For soaking treatment, take 200 milliliters of gentamicin, purify the mixed material, stir it into latex, and then spin the latex material into silk.

Embodiment 2

[0007] Embodiment two. Take 10g of collagen extracted from the tendon, 5g of chitin, and 2.5g of polyacrylamide hydrophilic hydrogel, a synthetic polymer material, and mix them. Take 1000ml of 0.9% sodium chloride injection for soaking treatment. Damycin 200 ml, the mixed material is purified, stirred into latex, and then the latex material is spun into silk.

Embodiment 3

[0008] Embodiment three. Cut the fresh beef tendon into slices, generally about 30 pieces per 10mm, wash with distilled water 4-5 times, put it into a glass container, add enzyme, the amount of enzyme added is 0.3-0.4g per 100g, The type of enzyme is fig glutenase. Put it in the incubator for 2-4 hours at a constant temperature of 30°C. After taking it out, wash it with distilled water for 3 times. Put it in and stir it for 6-8 hours, filter it with a filter, and make collagen extracted from the tendon after filtering. Make product by the method for embodiment one, two. Wherein the beef tendon is preferably the main tendon of the cow.

Abstract

An absorbable silk suture for skin is prepared from high-molecular material polypropylene collagen extracted from tendon (8-12g), chitin (4-6g), polyacrylamide hydrophilic gel (2-3g) through mixing and shaping to form the silk. Its advantages are naturally dropping off in 5-15 days after operation and no residual scar.

Description

(1) Technical field [0001] The invention relates to a material for surgery, specifically a suture thread. (2) Background technology [0002] Mostly adopt traditional real silk thread, nylon thread, catgut etc. to suture the postoperative position in surgical operation at present. The more advanced suture is mousse thread. These sutures are used to close the skin and will need to be removed after healing. American Johnson's subcutaneous absorbable suture has an absorption time of about 60 days in the subcutaneous tissue. If it is used for skin suturing, it may need to be removed. In the invention patent with the patent number ZL95105240.3, a material for surgical operations such as double eyelid surgery using polypropylene suture thread, a polymer synthetic material, is disclosed. It is widely used in clinical applications and is very popular among beauty lovers. However, the main component of this material is high-molecular synthetic polypropylene, which is high in conten...
