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.

Description

FIELD OF THE INVENTION

[0001] The present invention relates broadly to methods and devices for controlling movement of a working end of a surgical device. BACKGROUND OF THE INVENTION

[0002] Endoscopic surgical instruments are often preferred over traditional open surgical devices since the use of a natural orifice tends to reduce the post-operative recovery time and complications. Consequently, significant development has gone into a range of endoscopic surgical instruments that are suitable for precise placement of a working end of a tool at a desired surgical site through a natural orifice. These tools can be used to engage and / or treat tissue in a number of ways to achieve a diagnostic or therapeutic effect.

[0003] Endoscopic surgery requires that the shaft of the device be flexible while still allowing the working end to be articulated to angularly orient the working end relative to the tissue, and in some cases to be actuated to fire or otherwise effect movement of the working ...
