| Research Abstract |
Investigation on dissection growing in soft artificial tissue made of Polyacrylamide gel was carried out with micro water jet driven by spark discharge, and we tried to suggest multipurpose surgical knives inducing the dissection by the jet. As results, we could obtain conditions to produce the stable water jet with underwater spark, and the jet was suitable to apply to incision equipment. And about Coanda effect related to preservation of harder tissues like blood vessels in incision process, range of contact angle bring the effect to disk hard tissue was identified approximately in present studies. From these results, we can evaluate dissecting process under several conditions, and suggest jet generator for multipurpose incision with wide adjust range of the jet strength.
