Description

Easily degradable collagen line and preparation method thereof

Technical Field

The invention relates to an easily degradable collagen line and a preparation method thereof, belonging to the technical field of production and manufacturing of collagen lines.

Background

An absorbable suture line refers to a novel suture material which can be degraded and absorbed by a human body after being implanted into human tissues in the process of surgical suture, does not need to be removed, and is free from the pain of removing the suture.

However, the existing absorbable suture line has insufficient tension, is knotted and easy to break during suturing, is easy to be absorbed without wound healing, and causes the wound rupture accident, thereby bringing worry and worry to doctors clinically.

Preferably, the outer collagen fiber thread is provided with at least eight.

Preferably, the adjacent outer collagen fiber threads of each circle are closely arranged.

Preferably, the inner collagen fiber thread has a plurality of inner collagen fiber threads, and the plurality of inner collagen fiber threads are parallel to each other to form a bundle-like structure.

Preferably, the diameter of the inner collagen fiber filament is larger than that of the outer collagen fiber filament.

Preferably, the inner collagen fiber filament has the same diameter as the outer collagen fiber filament.

Preferably, the thickness of the sericin layer is 0.1-0.5 mm.

Preferably, the inner collagen fiber filament is not equal in diameter to the outer collagen fiber filament.

The invention also provides a preparation method of the easily degradable collagen thread, wherein a plurality of inner layer collagen fiber silk threads are arranged in parallel to form a bundle-shaped structure, a plurality of outer layer collagen fiber silk threads are wound on the outer side of the bundle-shaped structure, the plurality of outer layer collagen fiber silk threads are parallel to each other and spirally wound on the surface of the inner layer collagen fiber silk threads to form an outer layer, and finally, a silk glue layer is poured on the outer side of the outer layer, so that the fracture of the suture thread is reduced.

Preferably, the inner collagen fiber thread, the outer collagen fiber thread and the sericin layer are made of materials which can be absorbed by a human body.

Compared with the prior art, the invention has the following beneficial effects:

the easily degradable collagen thread meets the requirement of tension during sewing, and the inner layer collagen fiber silk thread, the outer layer collagen fiber silk thread and the sericin layer are all made of materials which can be absorbed by human bodies, so that the collagen fiber silk thread is conveniently absorbed by patients.
