    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 effecting movement of one or more components of a multifire device, such as a clip applier, hernia tacker, or skin stapler. In one exemplary embodiment, a surgical fastening instrument is provided having an elongate shaft with an end effector coupled thereto and adapted to apply one or more surgical fasteners to tissue. An electrically expandable and contractible actuator, such as an electroactive polymer actuator, can be used to drive a fastener advancing or forming assembly through the elongate shaft, thereby driving a surgical fastener into tissue. In another embodiment, an electrically expandable and contractible actuator, such as an electroactive polymer actuator, can be used to effect movement of an articulation joint formed between the elongate shaft and the end effector.

    摘要： A surgical stapling and severing instrument particularly suited to endoscopic procedures incorporates a handle that produces separate closing and firing motions to actuate an end effector. In particular, the handle produces multiple firing strokes in order to reduce the required amount of force required to fire (i.e., staple and sever) the end effector. A linked transmission reduces the required handle longitudinal length, yet achieves a rigid, strong configuration when straightened for firing. A traction biased firing mechanism avoids binding in driving this straightened linked rack in cooperation with an anti-backup mechanism, with a lockout mechanism that prevents releasing the closure trigger during firing. Furthermore, an external indicator gives feedback to the surgeon as to how far firing has progressed, as well as providing a manual retraction capability.
