A surgical robotic system includes a plurality of magneto sensors for measuring a torque, axial force, angle, position, or speed of various driven members in the surgical robotic system.

Surgical robotic systems

A surgical robotic assembly includes an instrument drive unit including a housing defining a longitudinal channel, a plurality of motors for performing functions of a surgical instrument, and a designated motor for rotating the instrument drive unit and the surgical instrument when the surgical instrument is attached to the instrument drive unit. The instrument drive unit allows for a top-loading or a side-loading of the surgical instrument thereto.

Robotic surgical assemblies

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.

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 disposed about the plurality of drive shafts, and a plurality of drive gears. Each electric motor includes a stator and a rotor disposed within the stator. Each drive gear is fixed to a corresponding drive shaft and is configured for interfacing with a corresponding driven member of the electromechanical surgical instrument. Each rotor is configured to rotate a corresponding drive gear in response to an activation of a respective electric motor to actuate a function of the electromechanical surgical instrument.

An instrument drive unit for use in a robotic surgical system includes a carriage configured to be coupled to a robotic arm, a hub rotationally coupled to the carriage and configured to be non-rotatably coupled to an electromechanical surgical instrument, a plurality of electric motors disposed within the carriage, a plurality of drive shafts rotationally supported in the hub, and a plurality of drive gears. Each electric motor includes a stator and a rotor disposed within the stator. Each drive gear is fixed to a corresponding drive shaft and is configured for interfacing with a corresponding driven member of the electromechanical surgical instrument. Each rotor is configured to rotate a corresponding drive gear in response to an activation of a respective electric motor to actuate a function of the electromechanical surgical instrument.
