Abstract

A surgical instrument includes a shaft, an end effector extending distally from the shaft, and a housing extending proximally from the shaft. The housing includes a motor configured to generate at least one motion to effectuate the end effector, and a power source configured to supply power to the surgical instrument, wherein the power source includes a casing, a data storage unit, and a deactivation mechanism configured to interrupt access to data stored in the data storage unit. In addition, the power source includes a battery pack and a deactivation mechanism configured to deactivate the battery pack if the casing is breached.
