ULTRASOUND SURGICAL APPARATUS

摘要

An ultrasound surgical apparatus includes: an ultrasound transducer that generates ultrasound vibrations; a driving portion that supplies a driving signal to the ultrasound transducer; a distal end portion that is mechanically coupled with the ultrasound transducer and treats a living tissue through a liquid; a detecting portion that detects a cavitation level signal corresponding to a state of cavitation generated in the liquid by ultrasound vibrations of the distal end portion; and an information acquiring portion that acquires information of the living tissue on the basis of the cavitation level signal.
