Methods and devices are provided for controlling movement of a working end of a surgical device. In one embodiment, methods and devices are provided for moving an end effector on a distal end of a surgical fastening device. Movement can include rotational movement of the end effector about an axis of the shaft, articulation of the end effector relative to the shaft, and actuation of an end effector, e.g., closing, firing, and/or cutting. In other embodiments, a single cable actuator is provided and is movable between a first position, in which it is effective to rotate an end effector without actuating (i.e., closing and firing) the end effector, and a second position, in which it is effective to actuate the end effector without rotating the end effector. In other aspects, methods and devices are provided for moving a flexible neck formed on a distal end of an accessory channel for use with an endoscope. Movement of the flexible neck can be used to control positioning of a tool extending through the flexible neck.

1. A surgical device, comprising: a powered handle;an elongate shaft operably coupled to and extending from the powered handle, the elongate shaft defining a shaft axis and including a flexible shaft portion;an end effector operably coupled to the flexible shaft portion and configured to perform at least one surgical procedure in response to at least one actuation motion applied thereto from the powered handle; anda plurality of flexible actuators operably coupled to the flexible shaft portion and the powered handle such that selective actuation thereof causes articulation of the end effector in at least two planes that are substantially perpendicular to the shaft axis, wherein the plurality of flexible actuators comprises a first flexible actuator operably coupled to one of the end effector and the flexible shaft portion and a first rotator operably supported in the powered handle. 2. The surgical device of claim 1 wherein the plurality of flexible actuators comprises: a second flexible actuator operably coupled to one of the end effector and the flexible shaft portion and a second rotator operably supported in the powered handle;a third flexible actuator operably coupled to one of the end effector and the flexible shaft portion and a third rotator operably supported in the powered handle; anda fourth flexible actuator operably coupled to one of the end effector and the flexible shaft portion and a fourth rotator operably supported in the powered handle. 3. The surgical device of claim 2 wherein: the first flexible actuator comprises a first actuator cable and wherein the first rotator comprises a first spool rotatably supported by the powered handle;the second flexible actuator comprises a second actuator cable and wherein the second rotator comprises a second spool rotatably supported by the powered handle;the third flexible actuator comprises a third actuator cable and wherein the third rotator comprises a third spool rotatably supported by the powered handle; andthe fourth flexible actuator comprises a fourth actuator cable and wherein the fourth rotator comprises a fourth spool rotatably supported by the powered handle. 4. The surgical device of claim 1 wherein the powered handle is electrically powered. 5. The surgical device of claim 1 wherein the powered handle is hydraulically powered. 6. The surgical device of claim 1 wherein the powered handle is pneumatically powered. 7. The surgical device of claim 1 wherein said end effector comprises: a first jaw; anda second jaw movably supported relative to the first jaw and being movably responsive to opening and closing motions applied thereto that are generated by a corresponding portion of the powered handle. 8. The surgical device of claim 1 wherein the flexible shaft portion of the elongate shaft comprises a flexible neck that is formed on a distal end of the elongate shaft. 9. The surgical device of claim 1 wherein the flexible shaft portion of the elongate shaft comprises a flexible neck formed on a proximal end of the end effector. 10. The surgical device of claim 1 wherein the flexible shaft portion of the elongate shaft comprises a separate flexible neck member located between the elongate shaft and the end effector. 11. A surgical device, comprising: a powered handle;an end effector configured to perform at least one surgical procedure in response to at least one rotary control motion applied thereto;an elongate shaft operably coupled to the powered handle and the end effector and extending therebetween, the elongate shaft defining a shaft axis and including a flexible shaft portion configured to facilitate articulation of said end effector in at least two planes that are substantially perpendicular to the shaft axis;a rotary drive shaft operably interfacing with the end effector to apply said at least one rotary control motion thereto;a rotary actuator operably supported by the powered handle and operably interfacing with the rotary drive shaft; anda first flexible actuator operably coupled to one of the end effector and the flexible shaft portion and a first rotator operably supported in the powered handle. 12. The surgical device of 11 further comprising a plurality of flexible actuators operably coupled to the flexible shaft portion and the powered handle such that selective actuation thereof causes articulation of the end effector. 13. The surgical device of claim 12 wherein the plurality of flexible actuators comprises: a second flexible actuator operably coupled to one of the end effector and the flexible shaft portion and a second rotator operably supported in the powered handle;a third flexible actuator operably coupled to one of the end effector and the flexible shaft portion and a third rotator operably supported in the powered handle; anda fourth flexible actuator operably coupled to one of the end effector and the flexible shaft portion and a fourth rotator operably supported in the powered handle. 14. The surgical device of claim 13 wherein: the first flexible actuator comprises a first actuator cable and wherein the first rotator comprises a first spool rotatably supported by the powered handle;the second flexible actuator comprises a second actuator cable and wherein the second rotator comprises a second spool rotatably supported by the powered handle;the third flexible actuator comprises a third actuator cable and wherein the third rotator comprises a third spool rotatably supported by the powered handle; andthe fourth flexible actuator comprises a fourth actuator cable and wherein the fourth rotator comprises a fourth spool rotatably supported by the powered handle. 15. The surgical device of claim 13 wherein at least one of the first, second, third and fourth rotators comprises a motor. 16. The surgical device of claim 11 wherein the rotary actuator is actuated by a motor supported by the powered handle.
