Claims (8)

ΟΊ 39753 83 901 103.8 Patentansprüche
1. Ultraschalloszillator mit einer Stromversorgungseinrichtung zum Gleichrichten eines Wechselstromsignals von einer Energiequelle zu einem Gleichstromsignal,
einem Verstärker zum Verstärken des Gleichstromsignals von der Stromversorgungseinrichtung, wobei der Verstärker eine Leistungsverstärkerschaltung zum Einstellen einer Amplitude einer abgegebenen Leistung davon ohne Phasenunterschied zwischen dieser abgegebenen Leistung und einem dazu zurückgeführten Signal und eine Zündimpuls vermindernde Schaltung zum Vermindern eines elektrischen Impulses während eines Startes der Oszillation einschließt,
einer Angleichungseinrichtung zum Angleichen eines Abgabesignals von dem Verstärker,
einer Rückführungseinrichtung zum Zurückführen gewisser Signale von der Angleichungseinrichtung zu der Leistungsverstärkerschaltung im Verstärker und
einem Ultraschallwandler mit einem Elektrostriktionswandler, der mit der Angleichungseinrichtung verbunden ist.
2. Ultraschalloszillator nach Anspruch 1, wobei die den Zündimpuls vermindernde Schaltung einen zwischen einem Oszillations-Zündschalter und einer Basis eines Transistors in Reihe geschalteten Widerstands und einen anderen Widerstand und einen Kondensator einschließt, die parallel zwischen die Basis des Transistors und einer Verbindung geschaltet sind.
3. Ultraschalloszillator nach Anspruch 1, bei dem die Leistungsverstärkerschaltung eine Parallelschaltung einer Diode und eines Kondensators, die mit einer Basis eines Verstärkungstransistors in Reihe geschaltet sind und eine Parallelschaltung eines Widerstandes und eines anderen Kondensators einschließt, die zwischen einem Emitter des
Transistors und einer Basis eines folgenden Transistors verbunden sind.
4. Ultraschalloszillator nach Anspruch 1, bei dem der Ultraschallwandler an einem vorderen Ende einen Schalltrichter, in dem eine Ansaugöffnung gebildet ist, einschließt, wobei ein Berieselungsrohr in einer Position nahe dem Schalltrichter angeordnet ist.
5. Ultraschalloszillator nach Anspruch 4, bei dem der Ultraschallwandler einen hohlen Elektrostriktionswandler einschließt und die Ansaugöffnung sich durch den Schalltrichter hindurch bis zu einem gegebenen Punkt einer rückwärtigen Platte erstreckt.
6. Ultraschalloszillator nach Anspruch 4, bei dem eine physiologische Salzlösung oder ähnliches durch das Berieselungsrohr zu einem befallenen Teil, an dem operiert werden soll, geleitet wird und bei dem ein Gewebe des operierten Teiles, das mit dem vorderen Ende des Schalltrichters in Berührung steht, durch in dem Schalltrichter erzeugte Ultraschal !vibrationen zerschlagen wird, wobei die physiologische Salzlösung oder ähnliches und die Zellstücke etc., die durch die Ultraschallvibrationen aufgeschwemmt werden, durch die Ansaugöffnung angesaugt und entfernt werden.
7. Ultraschalloszillator nach Anspruch 6, bei dem ein Material des Schalltrichters eine Titanlegierung ist.
8. Ultraschalloszillator nach Anspruch 6, wobei ein Handgriff, ein Verbindungsrohr und ein Schutzrohr jeweils aus einem Metall hergestellt sind, das leicht und beständig gegen Korrosion ist, vorzugsweise Aluminium oder Duraluminium.
