Sažetak
Minimally invasive ultrasonic surgery is one of the most recent field of application of ultrasound in medicine. The introduction of laparoscopic and endoscopic surgery, performed in the visual field of a miniature video camera, has pointed out the need for new solutions concerning micro-surgical instruments. 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 our study has been to optimize construction of an endoscopic surgical ultrasonic probe (ESUP) with respect to some specific technical, medicinal and operational/ergonomic requirements. The main design request was possibility of ESUP applications in the diferent surgical procedures. On the basis of the theoretical model, the ESUP was designed and realized as a rod-type resonant vibrating system, consisting of a half-wave length transducer and resonant wave guide in the form of a titanium wire of 1, 6 mm in dimeter. Multi functionality of the ESUP was verified with the shaping of the titanium wave guide and by measuring and calculating all the necessary parameters for the weighting of the electro-acoustical characteristics of the ESUP. The existance of the different modes of the vibration, in the frequency range of (20-40) kHz and as well electroacoustic characteristics of the ESUP at each of modes, enables efficient applications in different surgical applications.
