ABSTRACT:
An electrosurgical apparatus having a counter/lockout mechanism that monitors the number of sterilization/use cycles the electrosurgical apparatus undergoes and indicates the number of sterilization/use cycles that have actually been performed. The counter/lockout mechanism includes a temperature actuated element actuated in response to each sterilization cycle and a mechanically actuated element 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.
