dc.description.abstract心血管疾病一直以來都是人類健康與生命的首要威脅,傳統治療心血管疾病方面的手術分為藥物療法及外科手術等方式。但是傳統手術存在著風險高、手術難度大及費用昂貴等問題。因此,目前的醫療技術正轉型為由外科手術慢慢改變成新型的微創手術-血管支架(Stent)治療手術,這種微創治療手術以作為一種新的醫療方式而言,正以其侵入性低、傷口小、安全性高及減少主要器官可能的併發症等優點,越來越受到人們的關注。 本研究為利用SolidWorks有限元素軟體建構三種不同高複雜曲面的血管支架模型:MAC Stent、Maneo Stent及Palmaz Stent與316L不銹鋼、Ti-6Al-4V及N-Ti合金等三種材料來進行有限元素分析。主要模擬分析血管與支架歷經收縮、擴張等行為後,所產生的應力分佈情形,以了解支架植入血管內撐開血管管壁時,對血管管壁所造成的影響並針對支架幾何結構的不同及採用不同材料性質的情況下,探討支架結構與材料兩方面對支架應力大小及分佈的情形。zh_TW
dc.description.abstractCardiovascular diseases have been the primary threats of human health and life all the time, the traditional treatments of cardiovascular diseases are medicinal treatment and operation. But the traditional operation is full of high risk and hard to operate. Moreover, it also takes lots of money. Therefore, a new medical technology - Coronary Stent, is developing and paid more and more attention by people. It’s a new treatment with advantages such as low invasion, light wound, high safety, and reduces the possible complications of main organs. In this research, we build the stent models - MAC Stent, Maneo Stent, Palmaz Stent, which construct three kinds of different high complicated curved surfaces by SolidWorks, and execute finite element analysis. We analyze the stress distribution of blood vessel and stent got through contraction and dilation, to understand the influence on the wall of blood vessel when stent planted into blood vessel and brace the wall. In addition, set different materials including 316L stainless steel, Ti-6Al-4V and N-Ti alloy for each model, and probe into the stress value and distribution of these models.en_US
