    摘要: Methods and devices are provided for actuating and/or articulating a circular stapler. In one exemplary embodiment, a circular stapler is provided having an elongate shaft with a stapling apparatus coupled thereto. An electrically expandable and contractible actuator, such as an electroactive polymer actuator, can be used to pivotally or angularly adjust a position of the stapling apparatus relative to the elongate shaft by delivering energy to the electroactive polymer actuator. In another embodiment, an electroactive polymer actuator can be used to actuate the stapling apparatus, thereby driving one or more staples, preferably in a substantially curved pattern, into tissue. The actuator can alternatively or additionally drive a blade distally to cut tissue being stapled.

    摘要: A surgical stapling device. According to various embodiments, the stapling device comprises an end effector and a plurality of stacked actuatable wedge band sets. The end effector comprises an anvil having a staple forming surface and a staple cartridge facing the staple forming surface of the anvil. The staple cartridge comprises a plurality of staples and a plurality of staple drivers moveable supportable within the staple cartridge. Each staple driver is in contact with one of the staples and configured such that when the staple drivers are actuated, the staple drivers drive the staples through the staple cartridge so that the staples are formed against the staple forming surface of the anvil. Each stacked wedge band set comprises at least two different-level wedge bands for axially traversing the end effector. Each wedge band comprises a wedge cam at its distal end for driving certain ones of the staple drivers when the wedge band is actuated. A first of the two wedge bands in the stacks rides on a second of the two wedge bands in the stacks such that the staple drivers are driven in successive stages by the at least two wedge bands when the wedge bands are driven in succession. The cumulative height of a first of the plurality of stacked wedge band sets is less than a cumulative height of a second of the plurality of stacked wedge band sets.

    摘要: 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.
