Artificial bone material for repairing bone defects and preparation method of artificial bone particles
The invention relates to an artificial bone material for repairing bone defects. The artificial bone material is characterized by containing a plurality of artificial bone particles, and the artificial bone particles accumulate with each other to form the artificial bone material with porosity of 60%-90%; and each artificial bone particle comprises a main body part and a plurality of support columns formed at the main body part, the main body part is long-strip-shaped and comprises an upper surface and a lower surface which are oppositely arranged, the main body part further comprises a through hole penetrating through a space between the upper surface and the lower surface, and the support columns are arranged at the periphery of the main body part along the length direction of the main body part, stretch along the length direction and protrude from the main body part. According to the artificial bone material, the stability of the artificial bone material at a defected part can be improved.
本公开涉及一种修补骨缺损的人工骨材，其特征在于，包括多个人工骨颗粒，并且多个人工骨颗粒彼此堆积以形成孔隙率为60％至90％的人工骨材，人工骨颗粒包括主体部和形成在主体部的多个支撑柱，主体部呈长条状并具有相对设置的上表面和下表面，主体部具有贯穿上表面与下表面之间的贯通孔；多个支撑柱沿着主体部的长度方向设置在主体部的周围，支撑柱沿着长度方向延伸并从主体部突起。根据本公开，能够提高人工骨材在缺损部位的稳定性。
