A powered surgical stapler comprising: a housing; an endoscopic portion extending distally from the housing and defining a first longitudinal axis; a drive motor disposed at least partially within a housing; a firing rod disposed in mechanical cooperation with the drive motor, the firing rod translated longitudinally by the motor and including a first indicator and second indicator disposed thereon; an end effector disposed adjacent a distal portion of the endoscopic portion, the end effector in mechanical cooperation with the firing rod so that the firing rod drives a surgical function of the end effector; a position calculator for determining the current linear position of the firing rod, the position calculator coupled to a linear displacement sensor disposed adjacent to the firing rod and configured to detect linear movement of the firing rod; and a speed calculator for determining at least one of a linear speed of the firing rod and rotational speed of the drive motor. |
