Abstract
Abstract Ultrasound apparatus intended for the curettage or exeresis of biological tissues by irrigation of a liquid subject to cavitation and by suction of the disaggregated tissues, the apparatus comprising a hand-piece containing a transducer which is mechanically coupled to a vibrating instrument or sonotrode. Said apparatus is characterized in that the handpiece (1) is traversed in the longitudinal direction by a section conduit (15,24) connected on the one hand to a suction connector (3) provided at the backend of the end piece (1), and one the other hand to the internal part of the suction sonotrode (17).
