Abstract:
1. An electrosurgical instrument, comprising: a housing; an electrically conductive element at least partially supported in the housing and extending therefrom, the electrically conductive element adapted to connect to a source of electrosurgical energy; a motion sensor disposed within the housing and adapted to electrically connect to the source of electrosurgical energy, the motion sensor operable to detect a movement of the electrosurgical instrument in a plurality of directions; and wherein the motion sensor is operable to transmit a signal to the source of electrosurgical energy for de-activation of a transmission of energy from the source of electrosurgical energy when the motion sensor does not detect movement of the electrosurgical instrument for a period of time at least equal to a predetermined period of time, wherein the electrically conductive element includes a longitudinal axis defined therethrough and the motion sensor is operable to detect at least one of an axial movement of the electrosurgical instrument relative to the longitudinal axis, a transverse movement of the electrosurgical instrument relative to the longitudinal axis, and a rotational movement of the electrosurgical instrument about the longitudinal axis, wherein the motion sensor includes:
