Title (EN) ELECTROSURGICAL WAND WITH A SPACER AND WITH AN ACTIVE ELECTRODE, AN ASSOCIATED SYSTEM AND AN ABLATION METHOD INCLUDING GENERATING A PLASMA
(FR) BAGUETTE ÉLECTROCHIRURGICALE MUNIE D'UN ESPACEUR ET D'UNE ÉLECTRODE ACTIVE, SYSTÈME ASSOCIÉ ET PROCÉDÉ D'ABLATION COMPRENANT LA GÉNÉRATION D'UN PLASMA
Abstract:
(EN) An electrosurgical wand is disclosed. The electrosurgical wand includes a handle that defines a proximal end of the electrosurgical wand. The electrosurgical wand includes an elongate shaft coupled to the handle; the elongate shaft defines a suction lumen therein. The electrosurgical wand also includes an electrically insulative spacer (404) coupled to the distal end of the elongate shaft, whereby the spacer defines a suction channel (412) fluidly coupled to the suction lumen. The electrosurgical wand includes a first means for blocking defined by the spacer, an active electrode (402) coupled on the distal end of the spacer and a second means for blocking associated with the active electrode and in operational relationship to the first means for blocking. In the electrosurgical wand, the first means for blocking includes an annular trough (416) that fully encircles the suction channel of the spacer and the second means for blocking includes an annular wall (414).
(FR) L'invention concerne une baguette électrochirurgicale. La baguette électrochirurgicale comprend un manche qui définit une extrémité proximale de la baguette électrochirurgicale. La baguette électrochirurgicale comprend une tige allongée couplée au manche; la tige allongée définit une lumière d'aspiration à l'intérieur. La baguette électrochirurgicale comprend également un espaceur électriquement isolant (404) couplé à l'extrémité distale de la tige allongée, l'espaceur définissant un canal d'aspiration (412) couplé de manière fluidique à la lumière d'aspiration. La baguette électrochirurgicale comprend un premier moyen de blocage défini par l'espaceur; une électrode active (402) couplée sur l'extrémité distale de l'espaceur; et un second moyen de blocage associé à l'électrode active et en relation opérationnelle avec le premier moyen de blocage. Dans la baguette électrochirurgicale, le premier moyen de blocage comprend en outre un creux annulaire (416) qui encercle complètement le canal d'aspiration de l'espaceur et le second moyen de blocage comprend une paroi annulaire (414).
