Abstract

Un système électrochirurgical est décrit. Le système électrochirurgical comprend un générateur électrochirurgical conçu pour fournir de lénergie électrochirurgicale à un tissu. Le générateur électrochirurgical comprend un circuit de détection de limpédance qui mesure limpédance du tissu, un microprocesseur conçu pour déterminer si une réaction du tissu est survenue en fonction dune valeur dimpédance minimale et dune augmentation prédéterminée de limpédance, ladite réaction du tissu correspondant à un point débullition du fluide tissulaire, et un instrument électrochirurgical qui comprend au moins une électrode active conçue pour appliquer une énergie électrochirurgicale à un tissu. Une période de refroidissement du tissu est prévue pour améliorer les résultats fonctionnels.
