Title:
HOLLOW POROUS SPHERICAL PARTICLE ARTIFICIAL BONE, PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/153794
Kind Code:
A1
Abstract:
Disclosed is a method for preparing a hollow porous spherical particle artificial bone, the method involving: (1) uniformly mixing a bioceramic powder, a bioglass powder and an excipient to obtain a solid phase mixture, then adding a binder solution to the solid phase mixture, and uniformly mixing same to obtain a plastic wet material; (2) loading the plastic wet material into an extrusion device of an extrusion rounder, and extruding same through an orifice plate of the extrusion device to form a strip-shaped material; (3) placing the strip-shaped material into a rounding device of the extrusion rounder, cutting same, and then rounding same into spherical particles; and (4) placing the spherical particles into a furnace, degreasing same to remove the excipient and the binder, and then sintering same at 750℃-1550℃. Further disclosed are a hollow porous spherical particle artificial bone prepared by means of the preparation method and the use thereof. The obtained artificial bone has a hollow structure, a large number of macropores and micropores, a controllable pore structure, a high porosity, and a high strength, and has a good application prospect in the field of bone defect repair materials.
