Osteoinductive calcium phosphate ceramic with hollow tube structure and preparation method of osteoinductive calcium phosphate ceramic
The invention belongs to the technical field of biomedical materials, and discloses an osteoinductive calcium phosphate ceramic with a hollow tube structure and a preparation method of the osteoinductive calcium phosphate ceramic. The problem of contradiction between osteoinductive optimization and mechanical strength improvement of calcium phosphate ceramic in the prior art is solved. The preparation method comprises the following steps: placing porous calcium phosphate ceramic in a neutral or alkaline phosphorus-containing solution, and carrying out hydrothermal reaction and heat treatment to obtain the osteoinductive calcium phosphate ceramic with the hollow tube structure on the surface. The osteoinductive calcium phosphate ceramic with the hollow tube structure has the advantages of scientific design, simple method and simplicity and convenience in operation, and the osteoinductive calcium phosphate ceramic with the hollow tube structure on the surface is obtained through hydrothermal treatment and heat treatment. The calcium phosphate ceramic with the hollow tube structure not only has excellent osteoinductive capacity, but also has better mechanical strength, and meets the requirements of clinical partial bearing bone defect repair and regeneration.
本发明属于生物医用材料技术领域，公开了一种具有空心管结构的骨诱导磷酸钙陶瓷及其制备方法，解决现有技术中磷酸钙陶瓷面临的骨诱导优化与力学强度提高相互矛盾的难题。本发明的制备方法，将多孔磷酸钙陶瓷置于中性或碱性含磷溶液中，水热反应及热处理后即得到表面具有空心管结构的骨诱导磷酸钙陶瓷。本发明设计科学，方法简单，操作简便，通过水热处理和热处理后即得到表面具有空心管结构的骨诱导磷酸钙陶瓷。本发明的具有空心管结构的磷酸钙陶瓷不仅具有优异的骨诱导能力，而且具有较好的力学强度，满足临床部分承力骨缺损修复与再生的要求。
