    摘要： A surgical stapling device that comprises an end effector. According to various embodiments, the end effector comprises a circular 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 staple driver assembly comprising a plurality of staple drivers. Each staple driver supports one of the plurality of staples and is configured such that, when the staple driver assembly is actuated, each staple driver drives the staple into the staple forming surface of the anvil. A first quantity of the plurality of staple drivers has a first height and a second quantity of the plurality of staple drivers has a second height, wherein the first height is less than the second height.

    摘要： A surgical cutting and fastening instrument is disclosed. According to various embodiments, the instrument includes an end effector comprising an elongate channel, a clamping member pivotably connected to the channel, and a moveable cutting instrument for traversing the channel to cut an object clamped in the end effector by the clamping member when the clamping member is in a clamped position. The instrument may also comprise a main drive shaft assembly for actuating the cutting instrument in the end effector, a gear drive train connected to the main drive shaft assembly, and a motor for actuating the gear drive train. The instrument may also includes a closure trigger and a firing trigger, separate from the closure trigger, for actuating the motor when the firing trigger is retracted. Also, the instrument may comprise a mechanical closure system connected to the closure trigger and to the clamping member for causing the clamping member to pivot to the clamped position when the closure trigger is retracted.

    摘要： Access devices and related methods are disclosed that generally involve flexible or adjustable cannulas that have a substantially cylindrical insertion configuration and a substantially conical expanded configuration. Various methods and features are provided for transitioning the cannula from the insertion configuration to the expanded configuration while the access device is inserted through tissue to form a conical opening through the tissue. Examples include cables, biasing elements, retaining elements, bimodal rings, and coil springs. The devices and methods disclosed herein can allow for improved retention of the access device, improved angulation of instruments passed through the access device, and can increase the integrity of a seal formed between the access device and surrounding tissue.
