ENDO-CAVITARY THERAPEUTIC PROBE COMPRISING AN INTEGRATED IMAGING TRANSDUCER WITHIN THE ULTRASONIC THERAPY TRANSDUCER

摘要

Endo-cavitary therapeutic probe for the treatment of tissues, in particular of the prostate, by the emission of focused ultrasonic waves, comprising a support (2) forming a guide tube (4) extended by a mounting head (3) for a least one active surface therapeutic transducer element (7) emitting focused ultrasonic waves and having a spherical total surface face (9) in which a surface window is provided for mounting an imaging transducer (11); ). According to the invention, the therapy transducer element (7) has a front face (9) having a total area equal to the sum of the active area of 1500 mm 2 +/- 200 mm 2, and the window surface for the passage of the imaging transducer, the ratio of the window area to the active area of the therapy transducer element being less than or equal to 0.45.
