Composite soft tissue repair material stable in repair area

摘要

A composite soft tissue repair material stable in repair area, includes a middle mechanical reinforcement layer containing crosslinked acellular matrix; and upper and lower layers containing non-crosslinked acellular matrix, wherein the upper and lower layers completely encapsulate the middle mechanical reinforcement layer to form a sandwich structure. The present invention combines the advantages of crosslinked acellular matrix and non-crosslinked acellular matrix, including high histocompatibility, no viscera erosion, uniform thickness of the whole material, resistance to infection, long-term mechanical stability of the repair area, et al, which has good application prospects.
