摘要： Methods and devices are provided for actuating and/or articulating a surgical stapler. In one embodiment, a surgical stapler is provided having a stapling mechanism or end effector that is movably coupled to a distal end of an elongate shaft. 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 mechanism 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 staple applying assembly, thereby driving one or more staples, and preferably at least two linear rows of staples, 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： A surgical stapling and severing instrument particularly suited to endoscopic articulates an end effector by having a geared articulation mechanism that converts rotational motion from a handle portion. A firing bar longitudinally translates between the handle portion and the end effector. The firing bar head is thickened in order to present an undistorted cutting edge and engagement features to the opposing jaws of the end effector. The firing bar also advantageously includes a thinned or tapered proximal portion in the form of a strip or band that negotiates the articulation mechanism flexibility. To prevent buckling of the firing bar strip during firing, a pair of support plates adjustably flank the firing bar strip through the articulation mechanism. Various versions show resilient and spring engagement of each end of the support plate to distal and proximal sides of the articulation mechanism, as well as a resilient support plate.
