A biodegradable ceramic for medical use is disclosed, which comprises calcium hydrogenphosphate (CaHPO 4 ) modified by organic molecules. The organic molecule mentioned above is hexamethylene diisocyanate (HMDI), which is grafted to the calcium hydrogenphosphate through covalent bond. The present invention also relates to a method for preparing the biodegradable ceramics. In addition, the biodegradable ceramic can be used for repair of bone defects. Therefore, the present invention further relates to a method and a device for repair of bone defects, and to a delivery system for the medicine of repair of bone defects. |
