    • 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.
    • 公开了一种外科切割和紧固器械。 根据各种实施例,仪器包括端部执行器,其包括细长通道,可枢转地连接到通道的夹紧构件,以及可移动切割工具,用于横跨通道,以在夹紧时将夹紧在端部执行器中的物体夹紧在夹紧构件中 会员处于夹紧位置。 仪器还可以包括用于致动末端执行器中的切割仪器的主驱动轴组件,连接到主驱动轴组件的齿轮传动系以及用于致动齿轮传动系的马达。 仪器还可以包括闭合触发器和与闭合触发器分离的击发触发器,用于当击发触发器缩回时用于致动马达。 此外,仪器可以包括连接到闭合触发器和夹紧构件的机械闭合系统,用于当闭合触发器缩回时使夹紧构件枢转到夹紧位置。
