Abstract

A surgical instrument comprising an end effector, an articulation system, a firing system, a closure system, a lock system, and a control unit is disclosed. The end effector comprises a pair of movable jaws. The articulation system articulates the end effector when the articulation system is in an active state. The closure system is actuatable to move the pair of jaws. The lock system prevents the closure system from actuating when the lock system is in a locked state. The control unit controls the supply of power from a power source to the articulation system, the firing system, and the lock system. The control unit transitions the lock system to the locked state and prevents the supply of power from the power source to the firing system when the articulation system is in the active state.
