Abstract

Abstract Translated from French La présente invention concerne un appareil à ultra­sons permettant le curetage ou l'exérèse des tissus biologi­ques par irrigation d'un liquide soumis à la cavitation et par aspiration du tissu désagrégé, comprenant une pièce à main contenant un transducteur lequel est accouplé mécani­quement à un instrument vibrant ou sonotrode. The present invention relates to an ultrasonic device for curettage or excision of biological tissue by irrigation of a liquid subjected to cavitation and by suction of the disaggregated tissue, comprising a handpiece containing a transducer which is mechanically coupled to an instrument vibrating or sonotrode. Cet appareil est caractérisé en ce que la pièce à main (1) est traversée de part en part, dans le sens longi­tudinal, par un conduit d'aspiration (15,24) relié, d'une part, à un raccord d'aspiration (3) se trouvant à l'extré­mité postérieure de la pièce à main (1), et, d'autre part, à la partie interne de la sonotrode d'aspiration (17) This device is characterized in that the handpiece (1) is traversed right through, in the longitudinal direction, by a suction pipe (15, 24) connected, on the one hand, to a suction connector (3) located at the rear end of the handpiece (1), and, on the other hand, at the internal part of the suction sonotrode (17)
