Disclosed are a three-dimensional porous polyurethane stent for repairing central nerve injuries and a preparation method. The stent comprises three-dimensional porous polyurethane, wherein the compression modulus of same is 0.001-10.0 MPa, and the pore size of same is 10-200 microns. The three-dimensional porous polyurethane stent has an efficient central nerve repair function without the need for additional inoculation of functional cells or factors, and can partially restore the original nerve function of tested animals; and the preparation method is simple and has great application prospects. |
