Abstract

L'invention concerne un instrument électrochirurgical qui comprend des effecteurs terminaux opposés et une poignée destinée à réaliser le mouvement de ces effecteurs les uns par rapport aux autres. L'instrument comporte un logement et une paire d'électrodes, chacune comportant une surface électro-conductrice (par exemple, que l'on peut dimensionner pour suturer, pincer et/ou couper) et un substrat isolant dimensionné pour venir en contact avec les effecteurs terminaux de façon que les électrodes soient disposées à l'opposé l'une de l'autre. Les dimensions du substrat isolant diffèrent de celles de la surface électro-conductrice, ce qui permet de réduire la propagation thermique vers des structures tissulaires contiguës. Le substrat isolant est à base d'un matériau ayant un indice comparatif de résistance à l'érosion se situant entre environ 300 volts et environ 600 volts pour réduire l'incidence du contournement.
