Abstract
An ultrasonic, self-powered surgical device includes a handle, a self-contained power supply associated with the handle, and a control circuit disposed within the handle and/or the power supply. The control circuit is operable to carry out at least two operational conditions of the surgical device. A two-stage switch is electrically connected to the control circuit and effects the at least two operational conditions of the surgical device. A first stage of the switch effects a first of the at least two operational conditions and a second stage of the switch effects a second of the at least two operational conditions that is different from the first operational condition.
