Abstract:
Ein Energiebehandlungssystem und ein Ausgabesteuerverfahren dafür gemäß Ausführungsformen der vorliegenden Erfindung führen eine Behandlung durch Energiezufuhr aus, bei der Ultraschallenergie und Hochfrequenzenergie kombiniert sind, stoppen oder unterdrücken die Entladung durch Reduzieren der Ausgabe der Hochfrequenzenergie innerhalb eines Einstellungszeitraums, wenn ein Zustand, in dem Entladung während der Behandlung wahrscheinlich auftritt, erkannt wird, und ändern die Ausgabe der Ultraschallenergie. Zusätzlich wird, damit ein Benutzer die Behandlung ohne Unbehagen fortsetzt und um die Inzisionsleistung zu gewährleisten, jede Ausgabe gesteuert, so dass der Einstellungszeitraum so kurz wie möglich ist oder ergänzt wird, und außerdem der Einstellungszeitraum abläuft und eine Steuerung ausgeführt wird, so dass die Möglichkeit der Entladung sogar zur Zeit des Rückkehrens reduziert wird.
