A surgical instrument. The surgical instrument has an end effector and a trigger in communication with the end effector. The surgical instrument also has a first sensor and an externally accessible memory device in communication with the first sensor. The first sensor has an output that represents a first condition of either the trigger or the end effector. The memory device is configured to record the output of the first sensor. In various embodiments, memory device may include an output port and/or a removable storage medium.
1. A surgical cutting and fastening instrument comprising: a tissue-engaging end effector having a moveable tissue-cutting implement operably supported therein;a main drive shaft assembly operably interfacing with the end effector for transmitting an actuation motion to the movable tissue-cutting im
1. A surgical cutting and fastening instrument comprising: a tissue-engaging end effector having a moveable tissue-cutting implement operably supported therein;a main drive shaft assembly operably interfacing with the end effector for transmitting an actuation motion to the movable tissue-cutting implement therein;a gear drive train connected to the main drive shaft assembly;a motor for actuating the gear drive train;a motor actuator for controlling said motor;a reverse motor sensor for sensing an end of a cutting stroke of the tissue-cutting implement such that when the reverse motor sensor senses the end of the cutting stroke, the motor is signaled to reverse rotate to retract the tissue-cutting implement; anda stop motor sensor for sensing retraction of the cutting implement such that when the stop motor sensor senses retraction of the cutting implement, the motor is signaled to stop rotating. 2. The surgical cutting and fastening instrument of claim 1, wherein the end effector includes a staple cartridge. 3. The surgical cutting and fastening instrument of claim 1, wherein the end effector includes a helical drive screw, such that forward rotation of the helical drive screw causes the tissue-cutting implement to undertake the cutting stroke, and reverse rotation of the helical drive screw causes the tissue-cutting implement to retract. 4. The surgical cutting and fastening instrument of claim 1, wherein the main drive shaft includes articulation means for articulating the end effector. 5. The surgical cutting and fastening instrument of claim 1, wherein said end effector has a anvil movably supported thereon. 6. The surgical cutting and fastening instrument of claim 5 further comprising a closure actuator interfacing with said main drive shaft assembly to selectively apply opening and closing motions to said anvil. 7. The surgical cutting and fastening instrument of claim 6 wherein said main drive shaft assembly further comprises a closure tube movably interfacing with said anvil such that movement of said closure tube in a distal direction causes said anvil to move to a closed position and movement of said closure tube in a proximal direction, said closure tube causes said anvil to open. 8. The surgical cutting and fastening instrument of claim 1, wherein the end effector comprises: an elongate channel for carrying the cutting instrument; andan anvil pivotably connected to the elongate channel. 9. The surgical cutting and fastening instrument of claim 1, wherein the motor comprises a DC brushed motor. 10. A surgical instrument, comprising: an end effector comprising: an elongated channel configured to operably support a staple cartridge therein;an anvil movably supported relative to said elongated channel and being movable to a open positions relative to a staple cartridge within said elongated channel upon application of opening motions thereto, said anvil being movable to closed positions relative to the staple cartridge upon application of closing motions to said anvil; anda tissue cutting implement operably supported for reciprocatable movement within said elongated channel upon application of actuation and retraction motions thereto and wherein said surgical instrument further comprises:a shaft assembly connected to the end effector, said shaft assembly comprising: a drive shaft operably interfacing with said tissue cutting implement for transmitting said actuation and retraction motions thereto;a gear drive train operably interfacing with said drive shaft;a motor for actuating the gear drive train;means for controlling said motor;means for communicating resistive forces experienced by said tissue cutting implement to said means for controlling as said tissue cutting implement is driven through tissue clamped between said staple cartridge and said anvil; anda closure tube movably interfacing with said anvil such that movement of said closure tube in a distal direction causes said anvil to move to a closed position and movement of said closure tube in a proximal direction, said closure tube causes said anvil to open. 11. The surgical cutting and fastening instrument of claim 10 further comprising means for applying control motions to said closure tube. 12. A surgical cutting and fastening instrument comprising: an elongate channel configured to operably support a surgical staple cartridge therein;a clamping member pivotally connected to the elongate channel for selectively pivotal travel relative thereto upon application of opening and closing motions to said clamping member;a tissue-cutting implement operably supported within said elongate channel;a main drive shaft assembly operably interfacing with the end effector for transmitting an actuation motion to the movable cutting implement therein;a gear drive train connected to the main drive shaft assembly;a motor for actuating the gear drive train;a motor actuator for controlling said motor; anda sensor arrangement operably interfacing with said end effector and said motor actuator to communicate resistive forces experienced by said tissue-cutting implement to said motor actuator as said tissue cutting implement is driven through tissue supported between said clamping member and said staple cartridge. 13. The surgical cutting and fastening instrument of claim 12 wherein said main drive shaft assembly further comprises a closure tube movably interfacing with said anvil such that movement of said closure tube in a distal direction causes said anvil to move to a closed position and movement of said closure tube in a proximal direction, said closure tube causes said anvil to open.
