Abstract

L'invention concerne un système et des procédés d'utilisation correspondants servant à distribuer de l'énergie électrique par l'intermédiaire de multiples sondes refroidies. Le système servant à administrer de l'énergie à un tissu comprend : au moins deux dispositifs électrochirurgicaux destinés à délivrer de l'énergie au tissu; une source d'énergie destiné à être connectée auxdits deux dispositifs électrochirurgicaux et à fournir de l'énergie auxdits deux dispositifs électrochirurgicaux; au moins une source de fluide destinée à être accouplée auxdits deux dispositifs électrochirurgicaux servant à fournir un fluide auxdits deux dispositifs électrochirurgicaux; et un système de commande. Le système de commande est destiné à coordonner l'apport d'énergie depuis la source d'énergie auxdits deux dispositifs électrochirurgicaux avec l'apport de fluide depuis la source de fluide auxdits deux dispositifs électrochirurgicaux.
