Ultrasonic device for treating benign and malignant tissues deterioration, has cooling device with cooling fluid circulating unit, and acoustically active body formed of cooling fluid passing in cavity of body surrounding lens

摘要

The device (2) has an acoustic lens (6) mounted in front of an ultrasonic source, and a lens cooling device having a cooling fluid circulating unit and an ultra sound conductor. A body (7) surrounding the lens is made acoustically active by a cooling fluid (M) passing in a cavity (8) of the body. The body (7) is thin, permeable to the ultrasound, and fixes a contour of the lens.
