Abstract
(DE)
Elektrochirurgische Instrumente verfügen über Elektroden. Bei einer Verwendung dieser Instrumente als endoskopische Instrumente ist die Kontaktierung der Elektroden problematisch. Das vorliegende elektrochirurgische Instrument umfasst einen Sondenschlauch zum Transport von Fluid, mindestens eine Elektrode zur Devitalisierung von Gewebe und mindestens eine elektrische Leitung zum Bereitstellen einer HF-Spannung an der Elektrode. Für die einfache Kontaktierung der Elektrode ist die mindestens eine elektrische Leitung eine Leitungsfolie, die entlang der Längsachse des Sondenschlauchs angeordnet ist.
(EN)
Electrosurgical instruments have electrodes. When these instruments are used as endoscopic instruments, the contacting of the electrodes is problematic. The present electrosurgical instrument comprises a probe tube for transporting fluid, at least one electrode for devitalizing tissue and at least one electrical lead for providing an HF voltage at the electrode. For simple contacting of the electrode, the at least one electrical lead is a conducting foil which is arranged along the longitudinal axis of the probe tube.
(FR)
L'invention concerne des instruments électro-chirurgicaux présentant des électrodes. Lorsque de tels instruments sont utilisés comme instruments endoscopiques, la mise en contact des électrodes pose des problèmes. L'instrument électro-chrurgical selon l'invention comprend un tuyau sonde souple, pour le transport de fluide, au moins une électrode de dévitalisation du tissu, et au moins un conducteur électrique pour l'obtention d'une tension HF à l'électrode. Pour une mise en contact simple de l'électrode, au moins ledit conducteur électrique est une feuille conductrice qui est disposée le long de l'axe longitudinal du tuyau sonde souple.
