1. A surgical stapler, comprising:
- an end effector, comprising;
a firing member configured to move at least partially through said end effector;
a stop configured to create a lockout condition by impeding the advancement of said firing member through said end effector; and
a sensor configured to detect the lockout condition; and
a handle, comprising;
an electric motor configured to transmit a force to said firing member; and
a control system configured to control said electric motor, wherein said sensor is in communication with said control system, and wherein said control system controls said electric motor to adjust the force transmitted to said firing member when the lockout condition is communicated to said control system.

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.

8. A surgical instrument for cutting and stapling tissue, the surgical instrument comprising:
-
a handle, comprising; an electric motor; and a control system for controlling said electric motor; a shaft extending from said handle; an end effector extending from said shaft; a firing member, wherein said electric motor is configured to transmit a firing motion to said firing member, and wherein the firing motion advances said firing member at least partially through said end effector when said firing member is in a unlocked configuration; a lockout configured to prevent the advancement of said firing member when said firing member is in a locked configuration; and a sensor configured to detect a lockout condition when said firing member is in the locked configuration, wherein said sensor and said control system are in signal communication, and wherein said control system prevents said electric motor from transmitting the firing motion to said firing member when said sensor detects the lockout condition. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A surgical instrument for cutting and stapling tissue, said surgical instrument comprising:
-
a handle, comprising; motor means for driving firing means; and controlling means for controlling said motor means; firing means for ejecting staples, wherein said motor means advances said firing means; lockout means for locking said firing means; and sensing means for sensing when said lockout means is locking said firing means, wherein said sensing means is in communication with said controlling means, and wherein said controlling means prevents said motor means from advancing said firing means when said sensing means senses said lockout means is locking said firing means. - View Dependent Claims (16, 17, 18, 19, 20)
