The invention belongs to the field of medical repair materials and relates to a method for preparing a cell-free medical implant material. In the method for preparing the cell-free materials, neitherchemically synthesized detergents nor protease products are used to remove cells; but a plant-derived nonionic surfactant is used as a decellularizing agent, thus avoiding the damage of chemical detergents, protease preparations and the like to an ECM three-dimensional structure and the loss of effective active ingredients in ECM. The cell-free medical material prepared by the method can not onlybetter maintain the three-dimensional structure of ECM, but also allow more effective active ingredients to be remained in ECM and endowed with good mechanical properties. Thereby, the ability to induce chemotaxis and differentiation of host cells is stronger, and the effect of promoting tissue repair and regeneration will be better.
