Abstract

Un instrument électrochirurgical comprend un manche (28) ayant une configuration oblongue creuse ainsi qu'un ensemble électrochirurgical (48) dont les extrémités sont disposées à l'intérieur du manche creux et formant une boucle continue (33) pouvant passer d'un état agrandi à un état diminué et inversement sous la commande du manche. Un élément électrochirurgical contenu dans l'ensemble présente une surface extérieure (64) et un axe (65) ainsi qu'une lumière s'étendant le long de l'axe. Des parties transversales de l'élément définissent une pluralité de fentes (66) s'étendant transversalement à l'axe et permettant une communication fluide entre la lumière et la surface extérieure de l'élément. L'élément comprend un squelette isolé (64) et une pluralité de nervures (62) disposées de manière à s'étendre en une relation espacée mutuellement et transversalement au squelette.
