Abstract

La présente invention concerne une électrode permettant de couper un tissu biologique au moyen d'un courant haute fréquence. Lors de la coupe, des décharges de type arc électrique apparaissent entre une zone d'électrode qui est active et électroconductrice et le tissu. L'objectif de cette invention est d'éviter un flux de courant trop élevé dans le tissu, notamment lors de la découpe. Afin d'atteindre cet objectif, la zone d'électrode active comprend, au moins après le début du processus de coupe, plusieurs surfaces individuelles qui sont accessibles pour la formation de la décharge et sont séparées les unes des autres par des zones d'isolation, lesdites surfaces individuelles étant de dimensions très petites par rapport à une surface totale de la zone d'électrode active.
