Problems solved by technology

The main disadvantages of this method are: 1. During the natural drying process of the cleaned material, the material will be bent due to natural shrinkage, resulting in the unevenness of the suture body and the uneven surface. In the process of body diameter, it is easy to cause deviations in the results, resulting in suture tension that cannot meet the clinical use requirements, and there is a certain degree of risk; 2. After the suture is made, it is a suture without a needle. The tension of the site and the suture is temporarily selected with a normal hole suture needle, and at the same time the actual length of the suture is shortened, which is not conducive to surgical use, and also brings great trouble and inconvenience to clinicians.
After it is absorbed by the human body, there are a small amount of chemical substances remaining, which have a certain degree of poisonous effect on the human body, presenting a safety risk

Embodiment

[0019] (1) Raw material (coypu tendon tissue) extraction: healthy living coypu was killed, and the coypu tendon tissue was extracted by molding raw material extraction technology under relatively sterile conditions. The technical process of molding raw material extraction technology is as follows:

[0020] Body weight and tail length measurement of living healthy nutria → kill by concussion, bloodletting → wash the tail, disinfect the tail skin with 75% ethanol → cut the skin of the tip of the tail horizontally at 0.5 cm from the end of the tail with leather scissors, and then cut the skin of the tail longitudinally to At the root of the tail, expose the joint tissue of the tail → use coccyx forceps to break the joint from the distal end of the coccyx and extract the tendon tissue until it is 10 cm away from the joint at the base of the tail → separate the joint and tendon tissue with wire scissors, and clean the tendon tissue with sterile water 2-3 times to complete the extrac...

Abstract

The invention discloses a production method of suture prepared from nutria tendon tissue and its tensioner. The method comprises extracting tendon tissue from nutria, dewatering, degreasing, sterilizing, air-drying under tensile force, screening to obtain qualified tissue, separating out suture of different specification, and matching with non damage perforate pin or notch pin according to specification, and preparing into sutural line with pin. The inventive suture needle has smooth surface, uniform strip, accurate linear diameter, and good tensile force.

Description

technical field [0001] The invention relates to a processing method for making medical sutures from nutria tendon tissue, which is mainly a production process method for producing and processing the nutria tendon tissue into a finished product line after extraction and processing. Background technique [0002] The currently known production method of medical sutures for nutria tendon tissue is only reflected in the extraction of tendon tissue from the nutria body and the material treatment method after extraction, that is, the method of biological treatment of nutria tendon tissue, and does not involve the biological treatment of nutria tendon tissue. The specific production and processing process after the treatment is completed, that is, the production method of processing the nutria tendon tissue into medical sutures. The known medical suture extraction and biological treatment methods of nutria tendon tissue are as follows: 1. Kill the animal, and relatively aseptically ...
