Tissue repair hemostatic membrane as well as preparation method and application thereof

The invention belongs to the technical field of medical materials, and provides a tissue repair hemostatic membrane as well as a preparation method and application thereof. The method comprises the following steps: S1, taking non-human mammal skin tissues, pretreating, and sampling to a corium layer; the taken-down skin tissue is divided into an epidermal layer and a corium layer; s2, performing freeze thawing treatment on the material prepared in the step S1 to remove cells to obtain a matrix material; s3, a protective agent is applied to the matrix material, and freeze drying is carried out; and S4, after freeze drying, kneading or repeatedly folding to soften. Animal skin tissue which is wide in raw material source and low in cost is used, the matrix material is obtained after simple treatment, the tissue repair hemostatic membrane can be obtained after the gel material is arranged on the corium layer and freeze-dried, the used raw materials are wide in source and low in cost, the material treatment method
