  • Patent number: 12053179
    Abstract: A system and method of variable velocity control of an instrument by a computer-assisted device includes a computer-assisted device that includes an actuator and one or more processors. To perform an operation with an instrument coupled to the computer-assisted device, the one or more processors are configured to set a velocity set point of the actuator to an initial velocity, monitor force or torque applied by the actuator to actuate the instrument, when the applied force or torque is above a first force or torque limit, determine whether a total duration of a set of pauses occurring during the operation of the instrument is below a maximum pause threshold, and in response to determining that the total duration is below the maximum pause threshold, pause the operation of the instrument.

  • Publication number: 20220183687
    Abstract: A computer-assisted device include an actuator and one or more processors. The computer-assisted device is configured to support an instrument having an end effector located at a distal end. To perform an operation with the instrument, the one or more processors are configured to operate the end effector according to a state machine having a first state and a second state. In the first state a velocity set point of the actuator is set to a first velocity. In the second state the velocity set point of the actuator is set to a second velocity lower than the first velocity. The state machine transitions from the first state to the second state when a force or torque applied by the actuator is above a first threshold and transitions from the second state to the first state when the force or torque applied by the actuator is below a second threshold.

  • Patent number: 11291442
    Abstract: A system and method of variable velocity control of a surgical instrument in a computer-assisted medical device including an end effector located at a distal end of the instrument, an actuator, and drive mechanisms for coupling force or torque from the actuator to the end effector. To perform an operation with the instrument, the computer-assisted medical device sets a velocity set point of the actuator to an initial velocity, monitors force or torque applied by the actuator, reduces the velocity set point when the applied force or torque is above a first threshold, increases the velocity set point when the applied force or torque is below a second threshold, decreases the velocity set point to zero when the applied force or torque is above a maximum threshold, and drives the actuator based on the velocity set point. The first and second thresholds are lower than the maximum threshold.

  • Patent number: 11213360
    Abstract: Devices, systems, and methods for providing commanded movement of an end effector of a manipulator while providing a desired movement of one or more joints of the manipulator. Methods include augmenting a Jacobian so that joint movements calculated from the Jacobian perform one or more auxiliary tasks and/or desired joint movements concurrent with commanded end effector movement, the one or more auxiliary tasks and/or desired joint movements extending into a null-space. The auxiliary tasks and desired joint movements include inhibiting movement of one or more joints, inhibiting collisions between adjacent manipulators or between a manipulator and a patient surface, commanded reconfiguration of one or more joints, or various other tasks or combinations thereof. Such joint movements may be provided using joint velocities calculated from the pseudo-inverse solution of the: augmented Jacobian. Various configurations for systems utilizing such methods are provided herein.

  • Patent number: 10973519
    Abstract: A system and method of variable velocity control of a surgical instrument in a computer-assisted medical device includes a surgical instrument having an end effector located at a distal end of the instrument, an actuator, and one or more drive mechanisms for coupling force or torque from the actuator to the end effector. To perform an operation with the instrument, the computer-assisted medical device is configured to set a velocity set point of the actuator to an initial velocity and monitor force or torque applied by the actuator. When the applied force or torque is above a first force or torque limit it is determined whether a continue condition for the operation is satisfied. When the continue condition is satisfied the operation is paused and when the continue condition is not satisfied it is determined whether forced firing of the actuator should take place.
