Abstract

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.

Claims

1-21. -21. (canceled)

22. A surgical instrument system, comprising:

an end effector comprising a distal end, wherein said end effector is movable between an open configuration and a closed configuration when a closing motion is applied thereto;

a firing member movable toward said distal end when a firing motion is applied thereto;

a handle, comprising;

a closure actuator operable to generate said closing motion; and

a firing actuator;

a motor configured to generate said firing motion, wherein said firing actuator is operable to operate said motor; and

means for preventing said firing actuator from being operated prior to sensing the actuation of said closure actuator, wherein said means comprises a switch, wherein said firing actuator is configured to close said switch when said firing actuator is operated, and wherein said firing actuator cannot close said switch until said closure actuator is operated.

23. The surgical instrument system of claim 22, further comprising a staple cartridge.

24. The surgical instrument system of claim 22, wherein said handle is configured to receive a battery.

25. The surgical instrument system of claim 24, further comprising said battery positioned in said handle.

26. A surgical instrument system, comprising:

an end effector comprising a distal end, wherein said end effector is movable between an open configuration and a closed configuration when a closing motion is applied thereto;

a firing member movable toward said distal end when a firing motion is applied thereto;

a handle, comprising;

a closure actuator operable to generate said closing motion; and

a firing actuator;

a motor configured to generate said firing motion, wherein said firing actuator is operable to operate said motor; and

means for sensing the closure of said end effector, wherein said means comprises a switch circuit, wherein said firing actuator is configured to close said switch circuit when said firing actuator is operated, and wherein said firing actuator cannot close said switch circuit until said closure trigger is operated.

27. The surgical instrument system of claim 26, further comprising a staple cartridge.

28. The surgical instrument system of claim 26, wherein said handle is configured to receive a battery.

29. The surgical instrument system of claim 28, further comprising said battery positioned in said handle.

30. A surgical instrument system, comprising:

an end effector movable between an open configuration and a closed configuration when a closing motion is applied to said end effector;

a firing member configured to perform a staple firing stroke when a firing motion is applied to said firing member;

a handle comprising an actuator;

a motor configured to generate said firing motion, wherein said actuator is operable to operate said motor; and

a switch circuit configured to prevent said firing member from performing said staple firing stroke prior to sensing said closing motion.

31. The surgical instrument system of claim 30, wherein said handle further comprises a closure actuator operable to generate said closing motion.

32. The surgical instrument system of claim 30, further comprising a staple cartridge.

33. The surgical instrument system of claim 30, wherein said handle is configured to receive a battery.

34. The surgical instrument system of claim 33, further comprising said battery positioned in said handle.

35. A surgical instrument system, comprising:

an end effector movable between an open configuration and a closed configuration when a closing motion is applied to said end effector;

a firing member configured to perform a staple firing stroke when a firing motion is applied to said firing member;

a handle;

a motor configured to generate said firing motion; and

means for preventing said firing member from performing said staple firing stroke prior to sensing said closing motion, wherein said means comprises a circuit switch.

36. The surgical instrument system of claim 35, further comprising a staple cartridge.

37. The surgical instrument system of claim 35, wherein said handle is configured to receive a battery.

38. The surgical instrument system of claim 37, further comprising said battery positioned in said handle.
