Abstract
An electrosurgical instrument includes a housing having a treatment portion attached thereto. The treatment portion is adapted to connect to an electrosurgical generator that supplies energy to the electrosurgical instrument. An activation element is included and is disposed in electrical communication with the electrosurgical generator and the treatment portion. The activation element is selectively actuatable to supply energy from the electrosurgical generator to the treatment portion. A time-out device is coupled to the housing and is configured to prevent re-use of the electrosurgical instrument after a pre-determined time limit.
