Abstract
An instrument drive unit for use in a robotic surgical system includes a carriage configured to be coupled to a robotic arm, a plurality of drive shafts rotationally supported in the carriage, a plurality of electric motors, and a plurality of concentric, tubular shafts extending through the plurality of electric motors. Each electric motor includes a stator and a rotor disposed within the stator. Each drive shaft is configured for interfacing with a corresponding driven member of the electromechanical surgical instrument. A rotation of a rotor of an electric motor rotates a corresponding tubular shaft, which, in turn, rotates a corresponding drive shaft to actuate a function of the electromechanical surgical instrument.
