| 摘 要： | 目的探讨心脏起搏器在使用过程出现的问题及统计分析这些问题引起的潜在风险，对风险值最高的部件进行模拟分析并改善，保证心脏起搏器在寿命周期内的安全性和有效性。方法采用失效模式与效应分析（FMEA）研究心脏起搏器的潜在风险。结果统计得出心脏起搏器导线风险值最高，采用ANSYS软件模拟导线体结构，从微观方面探索导线体发生断裂时其结构特性的变化，并用导线机械性能理论对导线进行尝试性的改进。结论起搏器导线性能得到改善，心脏起搏器寿命得到延长。

| Abstract: | Objective To investigate issues of the cardiac pacemaker in use process and analyze potential risks caused by these issues, then to analyze and improve parts on highest risk value to ensure the safety and effectiveness of the cardiac pacemaker in the whole life cycle. Methods Using FMEA to study the potential risk of the cardiac pacemaker. Results The highest risk value of cardiac pacemaker is wire. The article adopts ANSYS to simulate wire structure to explore some changes in structure features from the micro when it fractures. Then tentative improvement was carried out on the wire according to the theory of wire mechanical property. Conclusion Performance of wire of the cardiac pacemaker is improved, service life of the cardiac pacemaker is extended. |
