ARTICULATABLE SURGICAL DEVICE WITH ROTARY DRIVEN CUTTING MEMBER
First Claim
1. A surgical device, comprising:
- an elongate shaft operably coupled to an actuator arrangement, the elongate shaft defining a shaft axis and including a flexible shaft portion;
a flexible rotary drive member operably supported by the elongate shaft and operably interfacing with a source of rotary actuation motions;
a surgical end effector operably coupled to a distal end of the elongate shaft, the surgical end effector comprising a tissue cutting member interfacing with the flexible rotary drive member and being movable within the end effector in response to an application of said rotary actuation motions to the flexible rotary drive member; and
a plurality of flexible actuators operably interfacing with the flexible shaft portion such that selective actuation thereof causes articulation of the end effector relative to the shaft axis.

Abstract
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.

14. A surgical device, comprising:
-
an end effector including a tissue cutting member configured to be selectively axially moved within the end effector; a hollow elongate shaft operably coupled to the handle and the end effector and extending therebetween, the hollow elongate shaft including a flexible shaft portion comprising a plurality of flexing portions and a plurality of restraining portions which cooperate to facilitate selective bending of the flexible shaft portion in two distinct planes; and a rotary drive shaft extending through the hollow elongate shaft and operably interfacing with the tissue cutting member such that rotation of the rotary drive member results in the axial movement of the tissue cutting member within the end effector. - View Dependent Claims (15, 16, 17, 18, 19, 20)
