    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： A piece of buttress material and an end-effector of a surgical instrument including features which can aid a surgeon in properly and quickly attaching the piece of buttress material to the end-effector. In various embodiments, a piece of buttress material can include retention features which can be engaged with portions of an end-effector to releasably retain the piece of buttress material to at least a portion of the end-effector. Similarly, an end-effector can include features configured to engage portions of a piece of buttress material to releasably retain the piece of buttress material to the end-effector. In at least one embodiment, more than one piece of buttress material can be releasably retained to an end-effector.
