    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 enables minimally invasive surgical procedures by having upper and lower jaws (i.e., anvil and staple channel) that are positioned with an elongate shaft and handle through a surgical opening, and in particular through a cannula of a trocar. A pair of fluid bladders (lift bags) are positioned in the staple channel beneath a proximally projecting lever tray so that transfer of fluid from the handle causes closing and clamping of the anvil. The bi-directional fluid control may be mechanically produced at the handle or by activating an electroactive polymer actuator. Once firing is sensed, an EAP plunger in a medical substance syringe inserted into the elongate shaft is activated to dispense a medical substance (e.g., anesthetics, adhesives, cauterizing substances, antibiotics, etc.) and is guided along a firing bar to a cutting surface of an E-beam placing the substance on tissue as severed.

    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: 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.
