Ultrasound type treatment apparatus
First Claim
1. An ultrasound type treatment apparatus comprising:
- ultrasonic oscillation means for outputting an ultrasonic oscillation wave, said ultrasonic oscillation means having an input terminal;
drive means for driving said ultrasonic oscillation means;
ultrasonic wave transmitting means, connected to said ultrasonic oscillation means, for transmitting the ultrasonic oscillation wave from the oscillation wave means to an affected region of interest of a human being;
communicating means formed around the ultrasonic wave transmitting means, through which cooling medium is passed;
supply means for supplying the cooling medium to said communicating means,monitor means for monitoring a drive state of said ultrasonic oscillation means and outputting monitor information;
determining means for receiving the monitor information from the monitor means and for determining whether or not the supply of the cooling medium to said communicating means is normal; and
control means for stopping a drive of the ultrasonic oscillation means when said determining means determines that the supply of the cooling medium is not normal.

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.

18. An ultrasound type treatment apparatus comprising:
-
ultrasonic oscillation means for outputting an ultrasonic oscillation wave; ultrasonic wave transmitting means, connected to said ultrasonic wave oscillation means, for transmitting the ultrasonic oscillation wave from said oscillation means to an affected region of interest in a patient; communicating means, formed around said ultrasonic wave transmitting means; and supply means for supplying a cooling medium to said communicating means; wherein said ultrasonic wave transmitting means defines a hole therein and comprises a probe using said hole as a first suction passage; said communicating means including an inner tubular sheath section covering said probe so as to define a space relative to said probe, and an outer tubular sheath section covering said inner sheath section so as to define a space relative to said inner sheath section, said inner sheath section having both a proximal end portion extending toward said ultrasonic oscillation means and a distal end portion extending toward a distal end of said probe, said outer sheath section having both a proximal end portion extending toward said ultrasonic oscillation means and a distal end portion extending toward the distal end of said probe; and a cooling medium supply passage and a second suction passage are provided, with one being between said probe and said inner sheath section, and the other being between said inner sheath section and said outer sheath section, said cooling medium supply supply passage and said second suction passage forming a cooling medium transmitting means. - View Dependent Claims (19, 20)
