Abstract

An apparatus includes a body, a shaft, a stapling assembly, and a sequential logic device. The body includes a safety switch, a firing actuator, and a motor. The stapling assembly is disposed at a distal end of the shaft, wherein the stapling assembly is configured to selectively move from an open position to a closed position to clamp tissue. The sequential logic device is operatively coupled with the motor and configured to detect an actuation of the safety switch and of the firing actuator. The sequential logic device is further operable to detect an order in which the safety switch and the firing actuator are actuated, compare the detected order to a predetermined order, and in response to determining that the detected order is equivalent to the predetermined order, transmit a motor activation signal to the motor.
