The stapler (10) includes a housing (110), an endoscopic portion (140) extending distally from the housing (110) and defining a first longitudinal axis (A-A), a drive motor (200) disposed at least partially within a housing (210) and a firing rod (220) disposed in mechanical cooperation with the drive motor (200). The firing rod (220) is rotatable by the motor (200) about the first longitudinal axis (A-A) extending therethrough. The stapler (10) also includes an end effector (160) disposed adjacent a distal portion of the endoscopic portion (140). The end effector (160) is in mechanical cooperation with the firing rod (220) to fire a surgical fastener. The stapler (10) further includes a current sensor (430) configured to measure a current draw on the motor (200) and a controller (600) configured to determine whether the surgical fastener is successfully deployed based on the current draw on the motor (200).4/59 04 -t CD d
