Claim 7:
8. A surgical device, comprising:
an elongate shaft extending distally from a proximal handle portion;
an end effector configured to move between an unarticulated position, in which the end effector is not articulated relative to the elongate shaft, and an articulated position, in which the end effector is articulated relative to the elongate shaft;
an actuator configured to be rotated in a first direction with the end effector in the unarticulated position and thereby cause the end effector to move from the unarticulated position to the articulated position, wherein continued rotation of the actuator in the first direction is configured to cause the end effector to move from the articulated position to the unarticulated position;
first and second movable members that are engaged with the actuator and operatively coupled to the end effector such that the rotation of the actuator in the first direction causes axial translation of the first and second movable members to thereby move the end effector from the articulated position to the unarticulated position and from the unarticulated position to the articulated position; and
first and second elongate members extending through the elongate shaft; wherein the first movable member includes a first drum coupled to the first elongate member, and the second movable member includes a second drum coupled to the second elongate member; wherein the rotation of the actuator in the first direction is configured to simultaneously move the first drum in a first direction and cause axial translation of the first elongate member and move the second drum in a second direction and cause axial translation of the second elongate member, the second direction being opposite to the first direction.
