摘要： An ultrasonic medical treating device suited for ultrasonic medical treatment of a prostate, capable of sighting a converging ultrasonic wave for the treatment precisely to a target portion, and preventing displacement from the target portion being irradiated effectively. An ultrasonic transducer (5) for generating a converging ultrasonic wave for treatment is arranged together with an imaging ultrasonic probe (6) in an applicator (4), and an ultrasonic transducer (2) for monitoring the sight of and the position displacement is provided in a catheter inserted in a ureter. Imaging means (7) drives the ultrasonic probe (6) to display an ultrasonic tomogram of the target portion and its vicinity on display means (10). The ultrasonic transducer (2) is driven pulsationally with the same frequency as that of the imaging ultrasonic wave at the timing at which the imaging ultrasonic wave, so that a point sound source image indicating the position of the transducer (2), as viewed from the applicator, is superimposed on the ultrasonic tomogram displayed on the display means (10). The position displacement of the applicator being irradiated with the converging ultrasonic wave can be monitored by monitoring the displacement from the position of the point sound source image at the end of the position adjustment of the applicator.

摘要： PROBLEM TO BE SOLVED: To provide an ultrasonic transmitter which is improved in transmission efficiency.
SOLUTION: The ultrasonic transmitter has a structure composed of a plurality of piezoelectric vibrators 1 arranged in a one-dimensional manner and an acoustic concave lens 3 stacked up on the vibrators 1, and the thinnest part of the acoustic concave lens is shorter than the wavelength of signals driving the piezoelectric vibrators and having the maximum frequency inside the acoustic concave lens. An acoustic layer 4 has an acoustic impedance intermediate between an acoustic impedance possessed by the acoustic concave lens and an average acoustic impedance possessed by a work as an object of testing, and is half or below as thick as the wavelength of the signals having the maximum frequency. The layer is laminated on the transmission surface of the acoustic concave lens 3. Electrodes 2-1 and 2-2 for driving the piezoelectric vibrators 1 are provided on both the sides of the piezoelectric vibrators 1. Lamb waves can be restrained from occurring in the acoustic concave lens and the piezoelectric vibrators.

摘要： PROBLEM TO BE SOLVED: To widen the therepeuticable range relating to the therapeutic section in the living body of an ultrasonic therapeutic applicator. SOLUTION: An ultrasonic vibrator transducer 2 for therapy which radiates converging ultrasonic waves to the therapeutic section 8 within the living body is disposed movably in a direction orthogonal with the longitudinal direction of a scanning drive shaft 3 which supports a probe 1 for diagnosis and the ultrasonic vibrator transducer 2 for therapy and scans and drives both in a longitudinal direction and around the axis. As a result, the converging ultrasonic waves radiated from the ultrasonic vibrator transducer 2 for therapy may be made to arrive at the desired therapeutic section 8 by evading a hindrance section 9. Then, the therepeuticable range relating to the therapeutic section in the living body of the ultrasonic therapeutic applicator may be widened.
