Bone repair stent material and preparation method thereof

Abstract

The invention relates to a bone repair stent material and a preparation method thereof, and the bone repair stent material can be used to overcome the defects of difficult obtainment of raw materials and ethical problems in the existing practice of taking a small bovine bone as the bone repair stent material. The bone repair stent material contains hydroxyapatite, the material is in a porous interpenetrating network structure, the porosity is 30%-85%, the macropore diameter is 100-800 microns, and the micropore diameter is 10-60 microns. The stent material can be widely used in repair treatment of bone defects and bone loss caused by diseases, traffic accidents, sports injuries and the like.

Description

technical field

[0001] The invention relates to a surgical repair material and a preparation method thereof, in particular to a bone repair scaffold material and a preparation method thereof. Background technique

[0002] At present, there are many patients with bone defects and loss caused by diseases, traffic accidents and sports trauma every year in the world, so the demand for bone repair materials for treatment is very large. Although the current research hotspots in the field of bone repair are focused on artificial synthetic materials to avoid the pain caused by autologous bone grafts, which are known as the "gold standard" of bone repair, including donor site surgery and dysfunction, and the sources are limited, but The scope of clinical application of artificial bone repair materials is still very narrow. Xenogeneic bone derived from calf bone is still used clinically, and its repairing effect has been widely accepted at present, but its raw material is from slaugh...
