本研究首先設計並製作了一部醫用水刀的原型機設備然後利用此設備進行相關的醫用水刀性能檢測實驗，本實驗探討了利用不同的醫用水刀操作壓力並搭配不同的水刀噴嘴直徑來產生不同的水刀沖擊壓力，並利用凝膠體模擬人體軟組織，以探討各種的水刀條件組合下，所能對人體組織可造成的切割深度與破壞情況，研究結果顯示在相同操作壓力下直徑越大的噴嘴其射出的水刀壓力越大，且其射出之後隨著距離與出口直徑比之增加其水刀壓力下降的弧度較大，也就是說其動量混合之作用比直徑較小的噴嘴較明顯，水刀切割的速率隨著操作壓力的增加而成線性關係，而且直徑越大的噴嘴隨著操作壓力的增加其切割速率也越快，在相同操作壓力之下直徑較大的噴嘴切割過豬的肝臟組織之後，所孤立不被切斷的血管較少，且在相同噴嘴直徑時隨著操作壓力的增加所孤立不被切斷的血管將更少。

The design and test of a water-jet cutter for medical application have been done in the Institute of Aeronautics and Astronautics of National Cheng Kung University. By using different operational pressure with different diameter of jet nozzle, the jet characteristic pressure and the modeling on tissue damage have been examined. The experimental results show that under the same operational pressure the jet of bigger nozzle diameter is offering higher jet pressure than a smaller nozzle diameter. The jet dynamic pressure decreases as the ratio of the distance between nozzle and pressure sensor being increased. For a jet of bigger nozzle diameter the dynamic pressure decreases smaller than a jet of smaller nozzle diameter. The depth of water jet cutting have a linear relation with the operational pressure. On the in vitro jet cutting on a pig’s liver under the same operational pressure, it has been observed that a jet with bigger nozzle diameter have lesser isolation blood vessels on the liver.
