THREE-DIMENSIONAL POROUS POLYURETHANE STENT FOR REPAIRING CENTRAL NERVE INJURIES AND PREPARATION METHOD

摘要

The present invention relates to a three-dimensional porous polyurethane scaffold for repairing central nerve injuries and a preparation method. The scaffold comprises three-dimensional porous polyurethane, wherein the compression modulus of the three-dimensional porous polyurethane is 0.001-10.0MPa and the pore diameter is 10-200µm. The three-dimensional porous polyurethane scaffold has an efficient central nerve repair function without additionally inoculating functional cells or factors and can partially restore the original nerve function of tested animals, the preparation method is simple and it has a great prospect of application.
