A silicon ultrasonic horn with a Bézier profile for surgical applications
نویسندگان
چکیده
A novel silicon ultrasonic horn with microprobes is developed for surgical applications. During insertion, penetration force of the microprobes driven by the ultrasonic horn can be reduced and tissue damage is minimized. The new horn has a profile of a Bézier curve. The dynamical characteristics of the horn are examined. Microscale prototypes are fabricated. Using the driving technique, the force reduction of microprobes during insertion will be investigated by experiments. Microprobes driven by the ultrasonic horns have potential applications in cardiac electrophysiology to provide information of wave propagation in hearts for understanding the mechanism of cardiac arrhythmia.

متن کاملA simple and novel method for acoustic streaming power measurement of ultrasonic horn
Ultrasonic horn with transfer of acoustic wave into an aqueous solution results in unique properties. When, transfer of sound wave into a liquid results in liquid movement in the direction of wave propagation which gradually loses its energy due to the viscous friction. This wave motion induces a flow which is known as acoustic streaming or micro-streaming. In this article, a simple innovative ...
