ULTRASOUND SUCTION SYSTEM

摘要

An ultrasound suction system applies an ultrasound driving signal generated by an ultrasound driving signal generating section onto an ultrasound generating section, transmits ultrasound vibration energy to a distal end portion via a vibration transmitting section, and, under observation by an observing section, fragments a treatment target living tissue with the ultrasound vibration energy, sucks fragmented living tissue pieces together with fluid supplied to a surface of the living tissue, and acquires by an image acquiring section an observed image in a state in which the ultrasound vibration energy is given. A control section controls output of the ultrasound driving signal on the basis of a result of comparison with a reference image.
