Bone tissue filling material

Abstract

The present invention provides a kind of bone tissue filling material. Spongy bone of ox is first treated to become inorganic matter, soaked in sodium pyrophosphate solution, dried and high temperature calcined to produce calcined bone tissue filling material. The filling material is soaked in suspension of zinc chloride, dried and high temperature calcined to obtain the zinc-containing calcined porous bone tissue filling material. The porous bone tissue filling material has low cost, good biocompatibility, homogeneous and communicated pores, certain mechanical strength, capacity of promoting bone growth and other features, and is suitable for filling bone deficiency, spinal column fusion and cell rack in bone tissue engineering, etc.

Description

technical field

[0001] The invention belongs to biomedical engineering materials, in particular to bone tissue filling materials. Background technique

[0002] Bone tissue filling materials are used in the repair of bone defects, spinal fusion, and cell scaffolds in bone tissue engineering. The traditionally used bone tissue filling materials have poor biocompatibility, high price, insufficient mechanical strength, and cannot effectively promote Insufficient bone growth, etc. Contents of the invention

[0003] The purpose of the present invention is to provide a bone tissue filling material, which has the characteristics of low price, good biocompatibility, uniform micropores communicating with each other, certain mechanical strength, and effective promotion of bone growth. At the same time, the invention also provides a planting method of the bone tissue filling material.

[0004] The bone tissue filling material provided by the invention is prepared by immersing bovine...
