Sažetak
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 changes in tissues and organs are reported. The aim of thies study has been to optimize construction of an endoscopic contact ultrasonic probe (ECUP) with respect to some specific technical, medical and operational/ergonomic requirements. The ECUP has been realized as a rod-type resonant vibrating system, consisting of a half-wave lenght transducer of piezoceramic material, and a resonant wave-guide in the form of a specially shaped velocity transformer. In order to avoid damage to healthy tissue because of focussing of high-energy ultrasound, 2D and 3D simulation of ultrasound field in the human scull was developed. To check the precision of simulation the measurements on real scull were carried out.
