摘要：A surgical instrument and method of controlling the surgical instrument aredisclosed. The surgical instrument includes a housing and an elongated shaft that

extends distally from the housing and defines a first longitudinal axis. The surgicalinstrument also includes a firing rod disposed in the elongated shaft and a drivemechanism disposed at least partially within the housing. The drive mechanismmechanically cooperates with the firing rod to move the firing rod. A sensor senses aparameter of light reflected from the surface of the firing rod, which includes markingsthat change the reflectivity of the firing rod. The measurement unit determines aparameter of the motion of the firing rod, such as the position and speed of the firingrod, based on the sensed parameter of the light reflected from the surface of the firingrod.
