Optimisation of ultrasonic probe for minimally invasive surgery

Minimally invasive ultrasonic surgery is the most recent field of application of ultrasound in medicine. Due to the principle of ultrasonic surgery (direct cutting, cavitation, fragmentation and thermal damage), the irreversible changges in tissues and organs are reported. The aim of our study has been to optimize construction of an endoscopic contact ultrasonic probe (ECUP) with respect to some specific technical, medicinal and operational/ergonomic requirements. On the basis fo the theoretical model, the ECUP was constructed and verified through extensive experiments. The ECUP has been realized as a rod-type resonant vibrating system, consisting of a half-wave length transducer of piezoceramic material, and a resonant wave guide in the form of a specially shaped velocity transformer. Special attention has been paid to the electro-acoustical characterisitcs (igh efficienty of the transducer, low losses in the wave guide, stability of the longitudinal vibrations at high amplitudes) of the transducer as well as of the specially shaped wave guide. Further intention is to test the ECUP in clinical applications.
