An electrode assembly, for the electrosurgical removal of tissue immersed in an electrically-conductive liquid, comprises an elongate support structure (12S) including at least a pair of conductors (12A, 12B) for carrying radio frequency electrosurgical currents. An electrically-insulative body (34) is mounted at a distal end of the support structure (12S), and extends transversely with respect to the support structure. A transversely-extending, conductive tissue treatment electrode (36) is secured to one side of the insulative body (34), and is electrically connected to one of the conductors. A transversely-extending, conductive return electrode (38) is secured to an opposite side of the insulative body (34).
L'invention concerne un ensemble électrode, destiné à l'élimination électrochirurgicale de tissus immergés dans un liquide électroconducteur, lequel ensemble comprend une structure (12S) de support allongée pourvue d'au moins une paire de conducteurs (12A, 12B) servant au transport de courants HF électrochirurgicaux. Un corps (34) électriquement isolant est monté à une extrémité distale de la structure (12S) de support; il s'étend de manière transversale à ladite structure de support. Une électrode conductrice (36) à extension transversale de traitement des tissus est fixée à l'un des côtés du corps isolant (34), et elle est connectée électriquement à l'un des conducteurs. Une électrode (38) conductrice transversale de retour à extension transversale est fixée au côté opposé du corps isolant (34).
