Abstract

Un dispositif de fusion à électrode intégré à un instrument électrochirurgical pour joindre des tissus comprend un premier et un deuxième éléments de mâchoire qui peuvent être déplacés d'une première position dans une relation espacée relative à une autre jusqu'à au moins une deuxième position pour saisir les tissus. Les éléments de mâchoire comprennent des plaques de scellement conductrices électriquement conçues pour transmettre de manière sélective l'énergie électrochirurgicale aux tissus disposés entre les deux plaques de scellement. Les éléments de mâchoire comprennent une plaque de refroidissement thermoélectrique ayant une première surface en contact direct avec une surface extérieure de la plaque à sceller. La plaque de refroidissement thermoélectrique comprend une première et une deuxième connexions sur les côtés opposés de l'élément de mâchoire. La première connexion est configurée pour transmettre sélectivement une première tension électrique et la deuxième connexion est configurée pour transmettre sélectivement une deuxième tension électrique de sorte que la chaleur produite par les plaques à sceller est transférée hors des tissus par la plaque de refroidissement thermoélectrique.
