Title:
ANTIBACTERIAL THREE-DIMENSIONAL POROUS BONE IMPLANT MATERIAL AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/168917
Kind Code:
A1
Abstract:
An antibacterial three-dimensional porous bone implant material. The antibacterial three-dimensional porous bone implant material comprises: a three-dimensional porous bone implant material; and an in-situ growth film layer in-situ growing on the surface of the three-dimensional porous bone implant material, wherein the in-situ growth film layer comprises a functional substance and an antibacterial substance, and the antibacterial substance comprises any one or more of zinc ions, copper ions, or silver ions. The in-situ growth film layer has an antibacterial effect. The macro pore size and micro pore size of the antibacterial three-dimensional porous bone implant material coexist, micro pores in a micro-arc oxidation film layer on a porous wall can provide anchoring points for bone growth, and the specific surface area of the implant material is effectively increased, and thus, the implant material in the early stage of implantation can have an antibacterial function and the biologically active functions of bone growth and bone induction.
