Abstract

An acellular matrix woven material, a preparation method and an application thereof are provided. The acellular matrix woven material is prepared by combining 3D printing with weaving. At the same time, also provided are the acellular matrix woven material prepared by the preparation method and its application in preparing tissue engineering scaffold materials.

First claim

What is claimed is:

1. A preparation method of acellular matrix woven material, wherein the acellular matrix woven material is prepared by 3D printing in conjunction with a weaving method;
specifically comprising the following steps:
cutting acellular animal tubular tissue with a rotary cutting method, twisting, and weaving warps after the 3D printing wefts to obtain the acellular matrix woven material, wherein the rotary cutting method comprises the following steps:
sleeving the acellular animal tubular tissue on a cylindrical mold, fixing on a rotary cutting device, and then cutting with a knife or laser in a spiral trajectory to obtain continuous acellular matrix strips; and
the weaving the warps after the 3D printing the wefts specifically comprises the following steps:
designing a weaving structure of a scaffold material according to a required macro shape, writing corresponding G code, printing acellular matrix fibers on a platform with regularly arranged needle tubes, weaving wefts of the scaffold material, replacing the needle tubes with the acellular matrix fibers, and weaving the warps of the scaffold material.

2. The preparation method according to claim 1 , wherein the animal tubular tissue is one among small intestine, large intestine, artery and vein; and
the animals comprise one or more among pigs, cattle, sheep, dogs, horses, rats and rabbits.

3. A acellular matrix woven material prepared by the preparation method according to claim 1 .

4. The acellular matrix woven material according to claim 3 , wherein a micro-woven structure of the acellular matrix woven material is one among plain weave, twill weave and satin weave fixed by interweaving and interlocking warps and wefts.
