Title (EN) SYSTEM AND METHODS OF CONTROLLING TEMPERATURE RELATED TO ELECTROSURGICAL PROCEDURES
(FR) SYSTÈME ET PROCÉDÉS DE RÉGULATION DE TEMPÉRATURE ASSOCIÉS À DES PROCÉDURES ÉLECTROCHIRURGICALES
Abstract:
(EN) Electrosurgical procedures. At least some of the example methods for detecting that an electrosurgical wand is effected by a blockage, including supplying a high frequency energy to an active electrode of an electrosurgical wand; drawing an electrically conductive fluid from the vicinity of the active electrode; sensing a temperature signal indicative of a temperature of the electrically conductive fluid drawn from the vicinity of the active electrode; and cycling the high frequency energy supplied upon the temperature of the electrically conductive fluid drawn from the vicinity of the active electrode exceeding a first threshold temperature.
(FR) La présente invention concerne des procédures électrochirurgicales. Au moins certains des procédés exemplaires pour détecter qu’une tige électrochirurgicale est affectée par un blocage comprennent l’application d’une énergie à haute fréquence à une électrode active d’une tige électrochirurgicale ; l’aspiration d’un fluide électriquement conducteur depuis le voisinage de l’électrode active ; la détection d’un signal de température indicatif d’une température du fluide électriquement conducteur aspiré depuis le voisinage de l’électrode active ; et le cyclage de l’énergie à haute fréquence appliquée lorsque la température du fluide électriquement conducteur aspiré depuis le voisinage de l’électrode active dépasse un premier seuil de température.
