| description | The present invention relates to surgical material. The material includes biological absorbable polymer 10-85 wt%, un-sintered calcium phosphate salt 5-80 wt%, and demineralized bone 1-70 wt%. The biologically absorbable polymer includes polyester, chitosan, hondroitin sulfate, collagen, alginatel, etc.; and the calcium phosphate salt is un-sintered hydroxyapatite or tricalcium phosphate of granularity less than 100 microns. The hard tissue repairing material is prepared through mixing biologically absorbable polymer, un-sintered calcium phosphate salt and demineralized bone dispersed in solvent and freeze drying to obtain the hard tissue repairing material. The composition has the function of promoting bone healing and excellent biocompatibility. |
