Motor-driven surgical cutting and fastening instrument with articulatable end effector
First Claim
1. A surgical cutting and fastening instrument comprising:
- 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;
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;
a motor for actuating the gear drive train;
a closure trigger for causing the clamping member to pivot to the clamped position when retracted;
a firing trigger separate from the closure trigger for actuating the motor when the firing trigger is retracted; and
means for articulating the end effector.

Abstract
A surgical cutting and fastening instrument is disclosed. According to various embodiments, the instrument includes an end effector comprising a moveable cutting instrument. The instrument also includes a main drive shaft assembly for actuating the cutting instrument in the end effector. The instrument also includes a handle comprising a gear drive train connected to the main drive shaft assembly, a motor for actuating the gear drive train, a closure trigger for causing the end effector to clamp an object positioned in the end effector when the closure trigger is retracted, and a firing trigger separate from the closure trigger for actuating the motor when the firing trigger is retracted. The instrument further comprises means for articulating the end effector.
