Abstract
A surgical instrument for use with a mechanized surgical system that includes a roll drive unit operable by a motor. The instrument includes an elongate shaft having a longitudinal axis, and an end effector and handle on the shaft. The handle includes an actuator manually operable by a user to mechanically actuate the end effector. The shaft includes a roll joint positioned between proximal and distal shaft portions, such that the distal shaft portion is longitudinally rotatable relative to the proximal shaft portion at the roll joint. The instrument further includes a drive segment on the distal shaft portion, the drive segment including first features rotationally engageable with second features of the roll drive unit such that operation of the motor causes the distal shaft portion to axially roll relative to the proximal shaft portion.
