1. A method of recording the state of a surgical instrument, the surgical instrument comprising:
- an end effector to engage tissue, the end effector comprising a staple channel and an anvil pivotable relative to the staple channel, where at least one of the anvil and the staple channel defines a longitudinal channel;
a reciprocating knife positioned to slide distally through the longitudinal channel;
a longitudinal shaft extending proximally from the end effector;
a first sensor having an output representing a position of the anvil relative to the staple channel;
a second sensor having an output representing a position of the reciprocating knife; and
an externally accessible memory device;
the method comprising;
monitoring the outputs of the first sensor and the second sensor;
recording the output of the first sensor to the memory device when a change occurs in the output of the first sensor; and
recording the output of the second sensor to the memory device when a change occurs in the output of the second sensor.

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.

10. A method of recording the state of a surgical instrument, the surgical instrument comprising:
-
an end effector to engage tissue, the end effector comprising a staple channel and an anvil pivotably translatable relative to the staple channel, wherein at least one of the anvil and the staple channel defines a longitudinal channel; a reciprocating knife positioned to slide distally through the longitudinal channel; a longitudinal shaft extending proximally from the end effector; and an externally accessible memory device comprising a wireless output port;
the method comprising the steps of;monitoring an output of a first sensor, wherein the output of the first sensor indicates a condition of at least one component selected from the group consisting of the anvil, the staple channel and the knife, then; recording the output of the first sensor to the memory device when at least one condition of the surgical instrument changes; and wirelessly communicating the output of the first sensor to an outside device via the wireless output port of the memory device. - View Dependent Claims (11, 12, 13, 14, 15, 16)
