Surgical fastener and cutter with mimicking end effector
First Claim
1. A surgical fastening device, comprising:
- an elongate shaft having a proximal end with a handle movably coupled thereto, and a distal end having an end effector extending therefrom, the end effector being adapted to engage tissue and deliver at least one fastener into the engaged tissue, wherein the handle and the end effector are coupled such that movement of the handle is mimicked by the end effector; and
a rotating member that is effective such that rotation of the rotating member relative to the handle is effective to selectively rotate the end effector and actuate the end effector to deliver at least one fastener into the engaged tissue.

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.

16. A surgical fastening device, comprising:
-
an elongate flexible shaft; a handle movably coupled to a proximal end of the elongate flexible shaft; an end effector having a flexible neck formed thereon and coupled to a distal end of the elongate flexible shaft, the end effector includes 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 having 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 extending between the handle and the end effector and effective to transfer forces from movement of the handle to the flexible neck to cause the end effector to mimic motion of the handle; and a rotating member that is effective to selectively rotate the end effector and drive at least one fastener into the engaged tissue. - View Dependent Claims (17, 18)
