Rotary actuatable surgical fastener and cutter
First Claim
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; and
an 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.

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.

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; and a 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. - View Dependent Claims (8, 9)

10. A surgical device, comprising:
-
an end effector configured to perform a plurality of surgical actions; and an 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; and an 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. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
