    Abstract: Surgical instruments and/or fastener apparatuses comprising an end effector with a pair of jaws pivoted at a proximal end thereof and movable between an open and closed position. At least one of the jaws may comprise a channel for receiving a cartridge containing a plurality of surgical fasteners. Also, an electrically powered actuator may be for deploying the surgical fasteners and may comprise a power source and a motor. An activation mechanism may be attached to the handle to move the pair of jaws from the open to the closed position and to activate the actuator. A lockout mechanism may be configured to permit current to flow from the power source to the motor when the pair of jaws is in the closed position and to prevent current from flowing to the power source to the motor when the pair of jaws is in the open position.

    Abstract: In one general aspect, various embodiments are directed to a surgical instrument that can supply mechanical energy and electrical energy to an end effector of the surgical instrument. The surgical instrument may be operated in a first operating mode in which a transducer of the surgical instrument produces mechanical energy, or vibrations, that are transmitted to the end effector and a second operating mode in which electrical energy, or current, can flow through the end effector to perform electrosurgery. In another general aspect, the surgical instrument may comprise a clamp, or jaw, which can be moved into a closed position to hold tissue against a waveguide, or blade, of the end effector. In the second operating mode of the surgical instrument, current can flow from a power source, through the waveguide, and return to the power source through a path comprising the jaw.
