Abstract

The invention discloses a porous composite biological material containing multiple active ions and a preparation method thereof, relating to the technical filed of production of medical materials. The porous composite biological material is a triple compound containing multiple active ions and calcium phosphate-silicate-calcium carbonate, and is composed of a porous ceramic structure main body containing active ions A and calcium phosphate-calcium carbonate and a phosphate-silicate cement coating, wherein both phosphate and silicate in the phosphate-silicate cement coating contain active ions B and calcium; and the phosphate-silicate cement coating accounts for 5-60% (mass percent) of the micropore structure main body. According to the invention, the exquisite three-dimensional intercommunication micropore structure of cuttlebone having extremely high porosity is kept, has excellent bone conductibility and favorable degradability, and can be subjected to stepped degradation; the release of the active ions and beneficial elements can be regulated and controlled; and the overall degradation rate of the material can be regulated according to different new bone formation requirements.

Description

[0001] The invention relates to the technical field of medical material production, in particular to a porous composite biological material containing multiple active ions and a preparation method.

[0002] Background technique

[0003] Human natural bone mineral is a compound containing elements such as Ca, P, C, Si, O, H, Zn, Sr, Mg, Mn, Cu, Fe, S, Al, Xi, K, Na, Cl and other trace elements thing. There is a wide range of isomorphic substitution behaviors in human bone mineralization engineering, so the mineral composition of human bone is very complex. Generally speaking, the main composition of human bone minerals is phosphate, followed by carbonate, and there is also a small amount of silicate. Simulating the composition and structure of human bone minerals is a strategic direction for the research and development of bone graft substitute materials or bone tissue engineering scaffolds. People hope that artificial bone can be degraded and implanted in the body to release...
