Abstract

Une électrode électrochirurgicale comprend un corps allongé présentant une surface perpendiculaire et des rebords latéraux longitudinaux formant des rebords de coupe longitudinaux adaptés pour la dissection électrochirurgicale le long dun plan. Le corps présente une configuration où lépaisseur du rebord latéral est supérieure à 0,01 po, formant deux ou plusieurs rebords de coupe, et le rapport entre la surface perpendiculaire et le nombre de rebords de coupe est inférieur ou égal à 0,0004 po2 par rebord de coupe.
