Production method of absorbable suture of mammal nerve fiber

Abstract

The invention relates to a method for preparing the nerve fiber absorbable suture thread, wherein it comprises: washing the nerve fiber to remove the surface dirt, to be washed in the hank's; removing resin and water in the alcohols with different densities, to be dipped in the stomach prolease solution and the internal shear enzyme solution; then washing it in the 5% pawpaw prolease; the invention can naturally remove the tail nerve fiber, to form hundreds of integral fiber lines, to improve the produced number and improve the extract rate to 100%. The invention has smooth surface without burr, while it removes the harmful organism in the nerve fiber, to avoid the rejection between human body and suture thread.

Description

technical field [0001] The invention relates to a preparation method of medical suture thread in medical supplies, in particular to a preparation method of mammalian nerve fiber absorbable suture thread. Background technique [0002] In the prior art, when dealing with skin trauma and performing an operation in a hospital, multi-level sutures should be carried out to the skin and subcutaneous tissues and organs. For the sutures on the skin surface, mostly high-strength nylon sutures are used. Finally, it can be taken out by removing the suture; and for the suture of the inner layer, it is impossible to take out the suture, only the suture that can be absorbed by the human body is used. In the prior art, the absorbable suture is mainly used for special purpose. Sheep catgut, and the special sheep catgut has a certain rejection phenomenon to the human body, which often causes a hard lump under the skin of the affected area, which brings additional pain and damage to the patien...
