An electrosurgical instrument including a housing assembly having a first disposable treatment portion selectively attached thereto. The disposable treatment portion is adapted to connect to an electrosurgical generator that supplies energy to the electrosurgical instrument. A control circuit is included and disposed in electrical communication between the electrosurgical generator and the first disposable treatment portion. The control circuit is selectively actuatable to enable the flow of electrosurgical energy from the electrosurgical generator to the first disposable treatment portion. An indicator, coupled to the housing assembly or the first disposable treatment portion, is configured to indicate a parameter related to the use of the electrosurgical instrument. The control circuit is configured to prevent activation of the electrosurgical instrument when the parameter of the indicator indicates the useful life of the disposable treatment portion has expired.
