The invention provides a nerve repair material, a preparation method and application. The nerve repair material is characterized in that: the nerve repair material comprises collagen, polysaccharide substances, active factors and nerve regeneration promoting factors, has a three-dimensional reticular porous structure, is non-immunogenic and degradable in vivo, and can be in a sheet shape or a hollow tubular shape. The nerve repairing material is made of porcine small intestine submucosa tissues, so that damaged nerves can be effectively protected, and a nerve regeneration protection microenvironment is formed; promoting regeneration of damaged nerves; the nerve protection film can also play a role in shielding, can effectively isolate the nerve injury part from peripheral tissues and prevent fibroblasts in the peripheral tissues from invading the nerve injury part. |
