Title:
CONTROL DEVICE AND TREATMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/123520
Kind Code:
A1
Abstract:
In the present invention, a high-frequency control unit outputs, to an end effector, first electric energy with a voltage waveform for generating discharge from the end effector. In a state where the first electric energy is outputted with the voltage waveform for generating the discharge, by control of the output of second electric energy to an ultrasonic transducer, a signal control unit performs control for oscillating the end effector with an oscillation frequency and an amplitude at which the end effector is not brought into contact with a to-be-treated object, thereby concentrating the discharge from the end effector in the traveling direction of the end effector.
