An electrosurgical apparatus (1) having a counter/lockout mechanism (10) that monitors the number of sterilization/use cycles the electrosurgical apparatus undergoes and indicates (22) the number of sterilization/use cycles that have actually been performed. The counter/lockout mechanism includes a temperature actuated element (70) actuated in response to each sterilization cycle and a mechanically actuated element (40) in response to a use cycle to effectuate a change of one or a plurality of indicia. The counter/lockout mechanism causes a single increment or decrement for each sterilization/use cycle that has been completed while also impeding use of the electrosurgical apparatus when the electrosurgical apparatus has undergone a predetermined number of sterilization/use cycles. In one embodiment, the distance of movement of the mechanically actuated element when fully actuated is greater than the distance the indicator moves when illustrating a change in the number of remaining uses.
L'invention porte sur un appareil électrochirurgical comportant un mécanisme de comptage et de verrouillage qui mesure le nombre de cycles de stérilisation/utilisation qu'effectue et qu'a effectué l'appareil. Ledit mécanisme, qui comporte un élément actionné par la température à chaque cycle de stérilisation et un élément actionné mécaniquement à chaque cycle d'utilisation et modifiant un ou plusieurs indicateurs, progresse ou régresse d'un pas à chaque cycle de stérilisation/utilisation accompli, et verrouille l'utilisation de l'appareil après un nombre prédéterminé de cycles. Dans une exécution, la course de l'élément actionné mécaniquement en cas d'actionnement complet est supérieure à celle de l'indicateur indiquant une modification du nombre des utilisations restantes.
