Title:
DEGRADABLE REGENERATIVE MEDICAL MATERIAL FOR PROMOTING TISSUE IN-SITU REGENERATION AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/252957
Kind Code:
A1
Abstract:
A degradable regenerative medical material for promoting tissue in-situ regeneration and a preparation method therefor. The degradable regenerative medical material is formed by means of chemically bonding Si, P, O, and metallic elements containing calcium, and is a regular three-dimensional net structure the material of which having a nano-scale mesoporous structure is a framework, and pores and micron-scale macropores that communicate with the pores are uniformly distributed in the regular three-dimensional net structure. The preparation method for the degradable regenerative medical material comprises the steps of mixing a sol, foaming, curing and calcination. The degradable regenerative medical material has a huge specific surface area, powerful biological activity and high biological safety, has the effect of promoting cell proliferation, may induce the rapid regeneration of its own damaged tissue cells, and achieve an in-situ tissue repair function.
