| Outline of Final Research Achievements |
Treatment-diagnostic device for minimally invasive surgery such as catheters treatment and endoscopes surgery has a problem that the output energy decreases by miniaturization. In this study, we developed a new structure to concentrate the energy to the lesioned part by propagating acoustic wave generated from a large actuator places outside of the body to the wire. The results of the study to establish a design method of a small ultrasonic therapeutic, the prototype devices was designed for thrombus stirring treatment, phacoemulsification surgery, ultrasonic scalpel and daVinci surgical robot.
