Modified magnesium-based bone cement powder and preparation method of modified magnesium-based bone cement
The invention relates to modified magnesium-based bone cement powder and a preparation method of modified magnesium-based bone cement, and is characterized in that the modified magnesium-based bone cement powder comprises magnesium or magnesium alloy fiber and magnesium-based composite powder; in the modified magnesium-based bone cement powder, the mass ratio of the magnesium-based composite powder with the particle size of 30-80 microns is at least 90%, and the diameter of the magnesium or magnesium alloy fiber is 0.05-0.09 mm; when the modified magnesium-based bone cement powder is used, the modified magnesium-based bone cement powder and a solvent need to be mixed, stirred and solidified into the modified magnesium-based bone cement. The magnesium or magnesium alloy fiber is used for improving the toughness of the modified magnesium-based bone cement. The preparation method of the modified magnesium-based bone cement comprises the following steps: drawing a magnesium or magnesium alloy material to prepare metal fibers, weighing and preparing, pulverizing, screening and drying, and mixing. The magnesium-based bone cement prepared from the modified magnesium-based bone cement powder is improved in mechanical strength and bone repair capacity.
本发明涉及一种改性镁基骨水泥粉剂及改性镁基骨水泥的制备方法，其特征在于，改性镁基骨水泥粉剂包括，镁或镁合金纤维和镁基复合粉末；在所述改性镁基骨水泥粉剂中，粒径为30～80μm的镁基复合粉末质量占比至少为90％，所述镁或镁合金纤维的直径为0.05～0.09mm；在使用时需将所述改性镁基骨水泥粉剂与溶剂混合搅拌凝固成改性镁基骨水泥；所述镁或镁合金纤维用于提高所述改性镁基骨水泥的韧性。本发明中的改性镁基骨水泥的制备方法，包括拉拔镁或镁合金材料制成金属纤维、称量配置、制粉、筛分干燥、混合。利用该改性镁基骨水泥粉剂制备的镁基骨水泥力学强度及骨修复能力均有所提高。
