Problems solved by technology

In 1997, Professor Zeng Jiaxiu brought his patent back to Xinhua, the hometown he had been away for many years, and established "Xinhua Huaxiang Rex Comprehensive Development Co., Ltd." In order to make the project develop faster, on the basis of stabilizing the original base, Professor Zeng Jiaxiu took several nephews to establish "Changsha Ranyuan Medical Protein Line Co., Ltd." in Changsha City. Later, due to insufficient funds, Accepted two shareholders, but in the end, because of being unkind, not only the company was taken away, but also he was illegally detained for half a year, his physical and mental health was greatly damaged, and he was hospitalized for cerebral hemorrhage surgery

Embodiment Construction

[0043] The present invention will be further described below in conjunction with embodiment.

[0044] The embodiment of the special rex civet medical collagen suture production process of the present invention is carried out according to the following steps:

[0045] Step 1: Soak the extracted collagen in 1% NaoH solution for 10 minutes to degrease;

[0046] Step 2: The defatted collagen is inactivated with 1mol / L NaoH, and cleaned with purified water 3-5 times;

[0047] Step 3: use dried milky white fish oil to soften the collagen after virus inactivation, and the mass ratio of collagen to milky white cod liver oil (unsaturated fatty acid) is 10:1;

[0048] Step 4: Use 3-3.5% H 2 o 2 Rinse the collagen, and further dehydrate the collagen with 75% ethanol;

[0049] Step 5: Using the principle of gravity, use a stainless steel wire management device to dry the collagen naturally;

[0050] Step 6: Sampling the collagen to detect geometric dimensions and tensile properties, ...

Abstract

The invention discloses a production process for medical special mampalon collagen suture lines. According to a scheme, eight production process steps for preparing the collagen suture lines are related. The production process is simple; and the collagen suture lines produced by the process have high performance, can be completely absorbed by a human body, and have far higher knot tensile strength than other suture lines.

Description

technical field [0001] The invention relates to an absorbable medical suture, in particular to a production process of a special rex civet medical collagen suture. Background technique [0002] There are two types of medical sutures, one is non-absorbable thread, such as silk thread, nylon thread, polyester braided thread, polypropylene thread, etc., which will not be absorbed in the body and form foreign bodies, which will affect incision healing after surgical infection. The other is absorbable thread such as gut, 910 glycolic acid lactic acid polyester thread, polyglycolic acid thread, polygluconate thread, polydioxanone thread, etc., which can be absorbed, but because it is a synthetic thread, its The production process goes through crushing, adding adhesives, wire drawing, coating and other processes. The product has low knotting and expansion strength, and takes a long time to absorb. It will form foreign bodies in the body, produce inflammatory reactions, foreign body...
