A bipolar electrosurgical forceps for treating tissue includes a pair of opposing first and second jaw members each having a tissue engaging surface disposed thereon. Each of the jaw members is movable relative to one another from a first position to approximate tissue to a second position for engaging tissue therebetween. The first jaw member includes a plurality of ring electrodes disposed thereon having a first electrical potential and the second jaw member includes a corresponding plurality of post electrodes disposed thereon having a second electrical potential. Each of the plurality of post electrodes is inwardly disposed of a respective ring electrode to form an electrode micro-sealing pad wherein upon activation of the forceps tissue grasped between each electrode micro-sealing pad is sealed while tissue adjacent to each electrode micro-sealing pads remains viable.

Ce forceps électrochirurgical bipolaire destiné au traitement de tissus comporte deux mâchoires, opposées l'une à l'autre, et portant chacune une surface de contact avec le tissu. Chacune des mâchoires est mobile par rapport à l'autre d'une première position d'approche du tissu jusqu'à une deuxième position de contact avec le tissu venant en prise. La première mâchoire porte une pluralité d'électrodes annulaires mises à un premier potentiel électrique, la deuxième mâchoire portant une pluralité correspondante d'électrodes en épaisseur mises à un deuxième potentiel électrique. Chacune des différentes électrodes en épaisseur est disposée intérieurement par rapport à l'électrode annulaire correspondante de façon à constituer un point de microsuture à électrode faisant qu'en agissant sur le forceps, le tissu saisi entre chaque point de microsuture à électrode se suture, le tissu voisin restant viable.
