Title (DE) BIPOLARES HOCHFREQUENZ-CHIRURGIEINSTRUMENT
(EN) BIPOLAR HIGH-FREQUENCY SURGICAL INSTRUMENT
(FR) INSTRUMENT CHIRURGICAL BIPOLAIRE A HAUTE FREQUENCE
Abstract:
(DE) Beschrieben wird ein Hochfrequenz-Chirurgieinstrument mit zwei Elektroden, die als Backen einer Zange ausgebildet sind, und an die ein HF-Strom eines HF-Generators derart anlegbar ist, daß ein hochfrequenter Strom zwischen den Backen durch den zu behandelnden Gewebebereich fließt. Das erfindungsgemäße Instrument zeichnet sich dadurch aus, daß zum wahlweisen Schneiden und Koagulieren ein elektrisch nicht leitender Abstandshalter vorgesehen ist, der beim Schneiden von Gewebe zwischen die Elektroden eingebracht wird, und daß wenigstens ein Kanal vorgesehen ist, der als Spül- und/oder Absaugkanal dient.
(EN) The invention concerns a high-frequency surgical instrument comprising two electrodes which are designed as forceps jaws and to which a high-frequency current from a high-frequency generator can be applied such that a high-frequency current flows between the jaws through the area of tissue to be treated. The instrument according to the invention is characterized in that, for alternative cutting and coagulation, an electrically non-conductive spacer is provided which is introduced between the electrodes when tissue is being cut. At least one duct is provided for flushing and/or removal purposes.
(FR) L'invention concerne un instrument chirurgical bipolaire à haute fréquence qui comprend deux électrodes se présentant sous forme de mâchoires de pince, et auxquelles un courant haute fréquence d'un générateur haute fréquence peut être appliqué, de manière qu'un courant haute fréquence circule entre les mâchoires à travers la zone tissulaire à traiter. Cet instrument se caractérise en ce qu'il est prévu, pour couper ou coaguler, un écarteur ne conduisant pas l'électricité, qui est inséré entre les électrodes lorsque des tissus sont sectionnés. Il est prévu au moins un canal servant de canal de rinçage et/ou de canal d'absorption.
