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

Technical field [0001] The present invention broadly relates to devices and methods for controlling the movement of the working end of surgical devices. Background technique [0002] Endoscopic surgical instruments are generally superior to traditional open surgical devices because the use of natural orifices tends to shorten postoperative recovery time and reduce complications. Therefore, the field of endoscopic surgical instruments suitable for accurately setting the working end of the tool at the desired surgical site through the natural orifice has been greatly developed. These tools can be used to join and / or treat tissues in a variety of ways to achieve diagnostic or therapeutic effects. [0003] The endoscopist needs the shaft of the device to be flexible while allowing the working end to be articulated in order to orient the working end at an angle with respect to the tissue, and for the shaft of the device to be actuated in some cases to fire or work端运动。 End sports.
