摘要

過去20多年來因非侵入式的醫治需求，水中震波聚焦於醫學上的應用正在擴大中。依據工業產品設計用的導向創新戰略方法（WOIS）和Pugh選擇法，本研究設計一體外震波產生器。所完成設計的體外震波產生器的零組件包含一線圈，一金屬圓盤，一聲學鏡片，一波介質，一容器，一容器罩和一組雷射輔助定位裝置。原先的產品設計程序中，經過WOIS分析，找出體外震波產生器的主要發展屏障，並以雷射輔助定位裝置克服該屏障。以Pugh選擇法篩選出最佳成品作為最後臨床用產品。所開發的成品性能經過實際測試和驗證，成品性能是依據平均聚焦壓力和平均能量強度，並確定有效焦距等於幾何焦距的特徵。雷射輔助定位裝置之建構和驗證，是透過雷射定位裝置呈現於患者皮膚上的正三角形，其邊長等於震波焦距（即皮下深度）。

The medical applications of focused underwater shock waves have increased during the last 20 years because of growing interest in noninvasive treatments. In this study, an electromagnetic-type shock wave generator is designed based on the way of oriented innovation strategy (WOIS) and Pugh's selection method for industrial product innovative design. The designed shock wave generator mainly consists of a coil, a metal disc, an acoustic lens, a wave medium, a container, and a container cap and laser-assisted positioning devices. A development barrier of electromagnetic-type shock wave generator was found in a design process by the problem field matrix of WOIS and overcome by laser positioning devices. A final clinic-purpose product is developed by Pugh's selection method for obtaining an optimal product. This developed product is tested for its performance based on average focused pressure and average energy intensity, having a characteristic of the effective focal length equal to the geometric focal length. The designed laser positioning devices are constructed and validated by showing a regular triangle on the patient skin. The regular triangle has a feature of its side length being equal to the depth from the treated target to the skin surface.
