介入治疗用支架力学性能的研究方法综述

介入治疗用支架是治疗管腔梗阻的新兴医疗器械，植入管腔狭窄部位后起支撑管腔和提高管腔畅通性的作用。理想的支架必须具备可靠的力学性能，而目前对支架力学性能的研究方法有理论分析、数值模拟和实验测试3种。对测定支架力学性能的各种分析方法及局限性进行详细地阐述和总结，并对支架后期的研究进行展望。
Interventional stents are emerging medical apparatus and instruments which can be implanted into the lesion location to reopen and scaffold the blocked cavities. The ideal stents must have reliable mechanical properties, and the current research methods on mechanical properties of the stents are mainly based on theoretical analysis, numerical analysis and experimental test. In this article, all kinds of analytic methods on testing mechanical properties of the stents and their limitations are discussed and summarized in detail, and further research on the stents is prospected as well.
