| titleOfInvention | An absorbable cervical intervertebral fusion device and its preparation method |
| abstract | The invention discloses an absorbable cervical intervertebral fusion device and a preparation method thereof. The fusion device is a bionic intervertebral fusion device made of nano-hydroxyapatite and polytrimethylene fumarate polymer composite materials; The preparation method of the fuser is to prepare the PPF/DEF mixed solution in proportion, add BAPO, and then add nano-hydroxyapatite, inject the prepared mixed solution into the plexiglass mold of the fuser, and polymerize it by ultraviolet light to make the fuser Prototype, and finally drilled teeth. The fusion device of the present invention has osteoinductive activity and in vivo absorbability, can be gradually degraded in vivo until fully absorbed by the human body, and can observe postoperative fusion conditions through X-rays, and is suitable for cases of anterior cervical intervertebral fusion and fixation. The preparation method of the present invention is simple, and can ensure better interfacial bonding between the inorganic component and the macromolecular material, and the mechanical strength of the obtained polymer is higher than that of the thermal crosslinking method, making its mechanical strength and elastic modulus closer to that of the human cancellous substance bone. |
