    摘要： A surgical tool can comprise an end effector, a shaft assembly, a rotatable drive shaft, a first electrical contact and a second electrical contact. The end effector comprises first and second jaw members that are pivotable relative to one another from an open position to a closed position and an electrode positioned on the first jaw member. The shaft assembly extends proximally from the end effector, is at least partially hollow, and defines an inner wall. The rotatable drive shaft extends proximally within the shaft assembly. The first electrical contact is coupled to the inner wall of the shaft assembly and positioned around at least a portion of the drive shaft. The second electrical contact is coupled to and rotatable with the drive shaft. The second electrical contact is positioned to be electrically connected to the first electrical contact as the drive shaft rotates.

    摘要： Methods and devices for using surgical devices with articulating end effectors are provided. Surgical devices with articulating end effectors can provide rotary driven pivoting of the end effector. In some embodiments, the device can include a handle, a first and a second tube extending from the handle, the second tube disposed within the first tube, and an end effector that includes a pair of distal jaws configured to move in response to rotation of the first tube about a longitudinal axis thereof and rotation of the second tube about a longitudinal axis thereof. The jaws can move in two different ways depending on whether the first and second tubes are rotating in a same direction as one another or in different ways than each other. The jaws can open/close and articulate using the same mechanical mechanism. The device can be powered, or the device can be non-powered.
