Abstract
An ultrasound type treatment apparatus includes an ultrasonic oscillation device for outputting an ultrasonic oscillation wave, a drive circuit for driving the ultrasonic oscillation device, a probe connected to the ultrasonic oscillation device to transmit that ultrasonic oscillation wave to an affected region of interest of a human being, a sheath formed around the probe, through which cooling medium is passed and a supply tank for supplying cooling medium to the sheath. In this treatment apparatus, an arithmetic operation circuit monitors a drive state of the ultrasonic oscillation device, a comparator is provided for receiving monitor information from the arithmetic operation circuit and for determining whether or not the supply of cooling medium to the sheath is normal and a controller is provided for stopping a drive of the ultrasonic oscillation device when the supply of the cooling medium is determined by the comparator as being not normal.
