Problems solved by technology

[0003] However, the tension of the current absorbable suture is not enough, it will be knotted and easily broken during suturing, and it is easy to cause the wound to be absorbed without healing, resulting in the accident of knife edge cracking. Therefore, it brings anxiety and worry to doctors in clinical practice.

Abstract

The invention relates to an easily degradable collagen thread. The easily degradable collagen thread comprises an inner layer of collagen fiber silk threads, a plurality of outer layers of collagen fiber silk threads and a sericin layer, wherein the outer layers of collagen fiber silk threads are parallel to one another and spirally wound on the surface of the inner layer of collagen fiber silk threads to form an outer layer, and the sericin layer is arranged on the surface of the outer layer. The invention further provides a preparation method of the easily degradable collagen thread. The easily degradable collagen thread has the following beneficial effects that the requirement for tension during sewing is met, and the inner layer of collagen fiber silk threads, the outer layers of collagen fiber silk threads and the sericin layer are all made of materials which can be absorbed by a human body, so that the easily degradable collagen thread is conveniently absorbed by a patient; meanwhile, the suture thread has the advantages of no irritation, no toxic or side effect and no scar at the stitch of the suture thread after healing.

Description

technical field [0001] The invention relates to an easily degradable collagen thread and a preparation method thereof, belonging to the technical field of collagen thread production and manufacture. Background technique [0002] Absorbable suture refers to a new type of suture material that can be degraded and absorbed by the human body after being implanted in human tissue during surgical suture, and does not need to be removed, so as to avoid the pain of removing the stitches. [0003] However, the tension of the current absorbable suture is not enough, and it will be knotted and easily broken during suturing, and it is easy to cause the wound to be absorbed without healing, causing the knife edge to burst. Therefore, it brings anxiety and worry to doctors in clinical practice. Contents of the invention [0004] According to the above deficiencies in the prior art, the technical problem to be solved by the present invention is: to solve one of the above problems, to prov...
