Motion detector for controlling electrosurgical output

An electrosurgical instrument having a movement sensing device for controlling the electrosurgical output thereof, is disclosed. In one aspect of the present disclosure, the electrosurgical instrument includes an elongated housing, an electrically conductive element supported within the housing and extending distally from the housing, the electrically conductive element connectable to a source of electrosurgical energy, and a sensor disposed within the housing and in electrical connection with the electrosurgical generator. The sensor detects movement of the electrically conductive element and communicates a signal to the electrosurgical generator relating to the movement of the electrically conductive element. The source of electrosurgical energy supplies electrosurgical energy in response to the signal from the sensor.
