    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.

    摘要: A surgical stapling device comprising an end effector. According to various embodiments, the end effector comprises an anvil having a staple forming surface and a plurality of staples facing the staple forming surface of the anvil. The end effector also comprises a plurality of staple drivers moveable supported within the staple cartridge. Each staple driver is in contact with one of the plurality of staples such that when the staple drivers are actuated, the plurality of staples are formed against the staple forming surface of the anvil. A first quantity of the staple drivers have a first height and a second quantity of the staple drivers have a second height, wherein the first height is less than the second height such that the staples driven by the first quantity of staple drivers have a longer formed length than the staples driven by the second quantity of staple drivers.

    摘要: A hydraulically actuated surgical instrument. The instrument may comprise a handle portion and a shaft. The shaft is mechanically coupled to the handle. The instrument may also include an end effector mechanically coupled to the shaft along its longitudinal axis. The end effector may comprise a surgical implement and a hydraulic device. At least a portion of the surgical implement may be translatable along a transverse axis, wherein the transverse axis is substantially perpendicular to the longitudinal axis of the shaft. Also, the hydraulic device may be positioned to be expandable toward the surgical instrument in a direction substantially parallel to the transverse axis of the shaft.

    摘要: A surgical instrument for laparoscopic and endoscopic clinical procedures simultaneously severs and staples tissue clamped in an end effector comprising an elongate channel, which holds a staple cartridge, and a pivotally attached anvil. An E-beam firing bar engages the channel and selectively engages the anvil during distal firing movements, wherein the tissue is severed and stapled driven upward from the staple cartridge to form against the anvil. In particular an upper pin of the firing bar is disengaged from the anvil before firing. A ramped transition from an anvil to an anvil slot avoids misfiring when the end effector has clamped too much tissue, yet assists in successfully clamping a slightly excess amount of tissue.
