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).
Claims11
Ultrasound apparatus for the curettage or exeresis of biological tissues by irrigation of a liquid subjected to cavitation and by suction of the disaggregated tissue, comprising:
- a hand-piece containing a transducer which is mechanically coupled to a sonotrode;
- a suction conduit within said hand-piece having a front end and a rear end and extending therebetween in a longitudinal direction in said hand-piece;
- a suction connector at the rear end of said hand-piece and connected to the rear end of said suction conduit;
- a suction sonotrode in said hand-piece connected to the front end of said suction conduit;
- and
- means traversing longitudinally right through said hand-piece and said sonotrode for allowing the transmission therethrough of at least one of a beam of hot light for illumination and/or of a cutting laser beam, for treatment or haemostatis.
An ultrasound apparatus for the curettage or exeresis of biological tissues by irrigation of a liquid subjected to cavitation and by suction of the disaggregated tissue, comprising:
- a hand-piece containing an ultrasonic transducer;
- two coaxial vibrating sonotrodes mechanically coupled to said transducer, said sonotrodes having front ends located in planes transverse to said hand-piece, and rear ends connected respectively to a suction connector and to an irrigation conduit means including a pair of conduits extending longitudinally in a space provided between the transducer and a wall of said handpiece.
