| titleOfInvention | A kind of preparation method of vertebral body filling material |
| abstract | The invention discloses a preparation method of a vertebral body filling material. First, CS powder is added into an acetic acid solution, Na 3 PO 4 is added after filtration, stirred and mixed to obtain liquid B, liquid A is added dropwise to liquid B, stirred and aged The precipitation is obtained by filtration and filtration, the precipitation is vacuum-dried and pulverized into powder, the powder is added to the mixed solution of citric acid and acetic acid, and the n-HA/CS binary complex is obtained by stirring; then a PHBV chloroform solution is prepared, and then added to In the PVA aqueous solution, emulsification to form a dispersion and continue stirring to evaporate chloroform to obtain PHBV microspheres; finally, the n-HA/CS binary complex and PHBV microspheres were dissolved in KH 2 PO 4 /K 2 HPO 4 buffer solution to obtain Vertebral filler material. The material obtained by the method provided by the present invention has the characteristics of matching biological and mechanical properties, close to cancellous bone in structure and strength, good biocompatibility and osteoconduction, and consistent rate of degradation and osteogenesis. |
