Summary: | INSTRUMENTS CHIRURGICAUX.BISTOURI ULTRA-SONIQUE CRYOGENIQUE COMPORTANT UN BOITIER 1, UNE SOURCE 2 D'OSCILLATIONS ULTRA-SONIQUES DISPOSEE DANS LE BOITIER 1 ET A LAQUELLE SONT RACCORDES UN TRANSMETTEUR 5 ET UN ECHANGEUR DE CHALEUR 7 TUBULAIRE POUR L'ADMISSION A UNE LAME 11 D'UN AGENT FRIGORIFIQUE ET SON EVACUATION, DISPOSE DANS LE BOITIER ET REALISE SOUS FORME D'AU MOINS DEUX TUBES 8, 9 COAXIAUX COMMUNIQUANT ENTRE EUX.APPLICATION EN CHIRURGIE DES TISSUS MOUS.
The appts. has coolant conducted to and from the blade (11) through a heat exchanger (7) consisting of at least two intercommunicating coaxial tubes (8,9). The transformer (5) is combined with the outer tube (8) for transmission of the ultrasonic waves from a source (2) composed of an excitation coil (3) and a magnetostrictive element (4). For max. efficiency the transformer (5) is shaped as a hollow frustum of a cone with its broader end (6) in contact with the source (2), and its narrower end (10) fixed to the outer tube (8). This has a lengthwise slit for airtight insertion of the comb edge (12) of the blade (11). |
