The therapy and imaging probe of the invention comprises a probe body (20') of an elongate shape defining a general axis (X-X), one imaging transducer (40') for transmitting imaging waves, and one therapy transducer (30') for transmitting therapy waves. The imaging transducer is mounted on first support means providing translational movement of the imaging transducer within the probe, parallel to the general axis (X-X) of the probe, between a withdrawn position and an extended position. The therapy transducer is mounted on second support means providing rotation of the therapy transducer within the probe, about an axis of rotation (X1-X1) parallel to the general axis (X-X) of the probe but offset with respect to the imaging transducer, to allow rotation of the therapy transducer between a withdrawn position and a treatment position. In the withdrawn or non-active position of the therapy transducer, the imaging transducer may be brought by translational movement to its extended position to occupy the place occupied by the therapy transducer in its treatment position. Thus, the imaging transducer may form an image of a region for treatment by the therapy transducer. In the treatment position of the therapy transducer, the imaging transducer is at its withdrawn position, The therapy transducer, during the transmission of therapy waves, directly transmits the therapy waves in a direction substantially identical to the direction in which the imaging transducer transmits the imaging waves when imaging waves are being transmitted.
La sonde endocavitaire (1) de thérapie et d'imagerie comporte un corps de sonde (3), au moins un transducteur d'imagerie (25) pour l'émission d'ondes d'imagerie et au moins un transducteur de thérapie (26) pour l'émission d'ondes de thérapie, montés mobiles dans ladite sonde, des moyens d'entraînement (24) dudit transducteur d'imagerie et des moyens d'entraînement (24) dudit transducteur de thérapie. Elle est caractérisée en ce que ledit transducteur de thérapie et ledit transducteur d'imagerie sont montés mobiles dans la sonde de telle sorte que ledit transducteur de thérapie lors de l'émission des ondes de thérapie émet directement les ondes de thérapie suivant une direction sensiblement identique à la direction suivant laquelle ledit transducteur d'imagerie émet les ondes d'imagerie lors de l'émission des ondes d'imagerie. L'invention permet de réaliser des traitements thérapeutiques, en particulier de la prostate, avec une très bonne efficacité et sécurité du traitement. La structure mécanique de la sonde de l'invention est simple, et permet d'obtenir une grande précision dans le traitement.
