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 fastening device, comprising: an elongate shaft defining a longitudinal axis and comprising a proximal end, and a distal end comprising an end effector extending therefrom, the end effector being adapted to engage tissue and deliver at least one fastener into the engaged tissue upon application of a rotary motion to the surgical fastening device;a rotating member operably coupled to an axially-translatable and rotatable drive shaft, said rotatable drive shaft being configured to rotate the end effector when said axially-translatable and rotatable drive shaft rotates in a first axial positon and when said axially-translatable and rotatable drive shaft is in a second axial position, said axially-translatable and rotatable drive shaft is configured to deploy fasteners upon application of the rotary motions to said rotatable drive shaft; andan actuator supported for movable travel about an actuator axis that is transverse to said longitudinal axis and operably interfacing with said axially translatable drive shaft to selectively move said drive shaft between the first and second axial positions relative to said end effector. 2. The surgical fastening device of claim 1 wherein said elongate shaft includes an inner lumen extending therethrough. 3. The surgical fastening device of claim 1 wherein said elongate shaft comprises: a flexible hollow tube; anda plurality of flexible actuators operably supported along said flexible hollow tube to be operably coupled to said end effector. 4. The surgical fastening device of claim 3, wherein the flexible hollow tube comprises a plurality of slits formed therein to facilitate flexion thereof. 5. The surgical fastening device of claim 4, wherein the flexible hollow tube includes a distal region of slits and a proximal region of slits, and wherein the slits are configured such that tension applied to the flexible hollow tube will cause the flexible hollow tube to bend at the proximal and distal regions. 6. The surgical fastening device of claim 1 wherein said end effector is pivotally or rotatably coupled to said elongate shaft. 7. A surgical fastening device, comprising: an elongate flexible shaft;a control member movably coupled to a proximal end of the elongate flexible shaft;an end effector comprising a flexible neck formed thereon and coupled to a distal end of the elongate flexible shaft, the end effector comprising opposed jaws adapted to engage tissue therebetween and adapted to drive at least one fastener into the engaged tissue, wherein the flexible neck includes a proximal region having slits formed on only one side thereof and a distal region comprising slits formed on only one side thereof, the proximal and distal regions of slits being formed on opposed sides of the flexible neck such that the proximal region of the flexible neck is configured to flex into a first position relative to the elongate flexible shaft and the distal region of the flexible neck is configured to flex in a position opposed to the first position relative to the elongate flexible shaft;an actuator arrangement extending between the control member and the end effector and effective to transfer forces to the flexible neck to cause the end effector to articulate in at least one plane;a rotary actuator operably interfacing with the end effector using an axially-translatable and rotatable drive shaft coupled to the rotary actuator such that when said rotary actuator is in one axial position, an application of a rotary control motion to said axially-translatable and rotatable drive shaft causes the end effector to perform a first action and when the rotary actuator is in another axial position, said application of the rotary control motion to said axially-translatable and rotatable drive shaft causes the end effector to deploy said at least one fastener; anda translation actuator movably supported relative to said rotary actuator and operably interfacing therewith such that when said translation actuator is pivotally moved in one direction, said rotary actuator is axially moved to one of said axial position and said another axial position. 8. The surgical fastening device of claim 7 wherein the actuator arrangement comprises a plurality of cables extending between the control member and the end effector, the cables being spaced apart from one another around a circumference of the flexible shaft. 9. The surgical fastening device of claim 7 wherein the control member is coupled to the proximal end of the elongate shaft by a joint selected from the group consisting of a ball and socket joint, a hinge joint, and a flexing joint. 10. A surgical device, comprising: an end effector configured to perform a plurality of surgical actions; andan elongate shaft coupled to said end effector and defining a shaft axis, the elongate shaft comprising:an elongate flexible portion configured to facilitate articulation of said end effector in two planes that are substantially perpendicular to the shaft axis upon manipulation of an actuation device relative to said elongate shaft such that movement of the actuation device is mimicked by said end effector; andan axially translatable rotary drive shaft operably interfacing with the end effector such that when in one axial position, an application of a rotary control motion thereto causes the end effector to perform a first surgical action and when the rotary drive shaft is in another axial position, said application of the rotary control motion thereto causes the end effector to actuate a firing member;and an actuator supported for movable travel about an actuator axis that is transverse to said shaft axis and operably interfacing with said axially translatable rotary drive shaft to selectively move said rotary drive shaft between said axial position and said another axial positon relative to said end effector. 11.
