| 中文摘要: |
| 对可生物降解镁合金血管支架的研究现状进行了综述。镁合金作为新型可降解物材料成为了研究热点,其中血管支架是其最有前景的应用方向之一。镁合金微细管材成形困难及镁合金血管支架腐蚀速率过快,是制约其大规模临床应用的2 个主要因素。作者介绍了近期国内外的相关研究,包括改善镁合金力学性能,以及为提高成形极限采取的新成形方法,为提高镁合金耐腐蚀性而采取的各种处理方法等。 |
| 英文摘要: |
| This paper reviews the research advance in biodegradable magnesium alloy for vascular stents. Magnesium alloys, as new biodegradable materials, have attracted much more attentions in recent decades. The vascular stent is one of the most promising applications of biodegradable magnesium alloys. Otherwise, the poor plasticity and fast corrosion rate of magnesium alloys are two major restrictions for their clinical applications of vascular stents. Some recent researches in grain refining, microtube fabrication and improvement corrosion resistance of magnesium alloy are reviewed from two aspects of material property and control of microtube dimensions. |
