Title:
ULTRASONIC MEDICAL TREATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2000/024328
Kind Code:
A1
Abstract:
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.
