Abstract

Claims (51)

1. An apparatus, comprising:

a restart of a surgical robotic system that is configured to be activated by a sterile user from within a sterile field without compromising the sterile field; and

a controller operatively coupled to the restart, the controller being configured to:

deactivate, in response to detecting an abnormal event, teleoperation of a slave manipulator of the surgical robotic system by a master console of the surgical robotic system;

detect that the restart has been activated by the sterile user from within the sterile field;

in response to detecting that the restart has been activated, determine whether an instrument is coupled to the slave manipulator of the surgical robotic system; and

in response to determining that the instrument is coupled to the slave manipulator, enable telemanipulation of the instrument in a predefined set of degrees-of-freedom (DOFs).

2. The apparatus of claim 1 , wherein the restart includes one or more physical or virtual buttons, switches, or sliders.

3. The apparatus of claim 2 , wherein the controller is configured to detect that the restart has been activated when the one or more physical or virtual buttons, switches, or sliders have been activated for a predefined period of time.

4. The apparatus of claim 2 , wherein the controller is configured to provide haptic, audible, or visual feedback while or after the one or more physical or virtual buttons, switches, or sliders have been activated.

5. The apparatus of claim 1 , wherein the restart includes a plurality of buttons, switches, or sliders.

6. The apparatus of claim 5 , wherein the controller is configured to detect that the restart has been activated when the plurality of buttons, switches, or sliders has been activated according to a predefined sequence.

7. The apparatus of claim 1 , wherein the instrument includes a set of jaws, and the predefined set of DOFs is one or more DOFs that allow the set of jaws to open or close.

8. The apparatus of claim 1 , wherein the instrument includes a hook, scalpel, spatula, needle holder, dissector, scissors, or grasper, and the predefined set of DOFs is a DOF associated with a rotational motion of the hook, scalpel, spatula, needle holder, dissector, scissors, or grasper.

9. The apparatus of claim 1 , wherein the restart is located on the master console of the surgical robotic system.

10. The apparatus of claim 1 , wherein the restart is located on the slave manipulator.

11. The apparatus of claim 1 , wherein the controller is further configured to:

detect, after determining that the instrument is coupled to the slave manipulator, that the instrument has been decoupled from the slave manipulator; and

after the instrument has been decoupled from the slave manipulator, restart the surgical robotic system.

12. The apparatus of claim 11 , wherein the controller is further configured to return the slave manipulator to a home position after restarting the surgical robotic system.

13. The apparatus of claim 1 , wherein the abnormal event includes at least one of: unexpected movement of at least one of the slave manipulator or the instrument, an input anomaly associated with the master console, a collision between (1) at least one of the slave manipulator or the instrument and (2) an external object, or a failure of a sensor, actuator, or controller of the surgical robotic system.

14. The apparatus of claim 1 , further comprising the master console disposed separately from the slave manipulator, wherein the master console includes a first plurality of links that are configured to be operatively coupled to a second plurality of links of the slave manipulator to enable teleoperation of the slave manipulator by the master console,

wherein the restart is located on the master console proximate to or on the first plurality of links.

15. The apparatus of claim 14 , further comprising a sterile handle configured to be removably coupled to the master console,

wherein the sterile handle, when coupled to the master console, is configured to control telemanipulation of the instrument in the predefined set of DOFs.

16. The apparatus of claim 14 , further comprising a sterile barrier configured to isolate a portion of the master console from the sterile field, the restart being located on the portion of the master console behind the sterile barrier.

17. The apparatus of claim 1 , wherein the slave manipulator is a first slave manipulator, and the instrument is a first instrument, the controller further configured to:

in response to detecting that the restart has been activated, determine whether a second instrument is coupled to a second slave manipulator of the surgical robotic system; and

in response to determining that the second instrument is coupled to the second slave manipulator, enabling telemanipulation of the second instrument in a predefined set of DOFs.

18. The apparatus of claim 1 , wherein the controller is configured to enable telemanipulation of the instrument in the predefined set of DOFs by enabling telemanipulation of the instrument to open before enabling telemanipulation of the instrument in any other DOFs.

19. An apparatus, comprising:

a restart of a surgical robotic system that is configured to be activated by a sterile user from within a sterile field without compromising the sterile field; and

a controller operatively coupled to the restart, the controller being configured to:

detect that the restart has been activated;

in response to detecting that the restart has been activated, determine whether an instrument is coupled to a slave manipulator of the surgical robotic system;

in response to determining that the instrument is coupled to the slave manipulator, enable telemanipulation of the instrument in a predefined set of degrees-of-freedom (DOFs);

detect, after enabling telemanipulation of the instrument, that the instrument has been decoupled from the slave manipulator; and

after the instrument has been decoupled from the slave manipulator, restart the surgical robotic system.

20. The apparatus of claim 19 , wherein the restart includes one or more physical or virtual buttons, switches, or sliders.

21. The apparatus of claim 20 , wherein the controller is configured to detect that the restart has been activated when the one or more physical or virtual buttons, switches, or sliders have been activated for a predefined period of time.

22. The apparatus of claim 20 , wherein the controller is configured to provide haptic, audible, or visual feedback while or after the one or more physical or virtual buttons, switches, or sliders have been activated.

23. The apparatus of claim 19 , wherein the restart includes a plurality of buttons, switches, or sliders.

24. The apparatus of claim 23 , wherein the controller is configured to detect that the restart has been activated when the plurality of buttons, switches, or sliders has been activated according to a predefined sequence.

25. The apparatus of claim 19 , wherein the instrument includes a set of jaws, and the predefined set of DOFs is one or more DOFs that allow the set of jaws to open or close.

26. The apparatus of claim 19 , wherein the instrument includes a hook, scalpel, spatula, needle holder, dissector, scissors, or grasper, and the predefined set of DOFs is a DOF associated with a rotational motion of the hook, scalpel, spatula, needle holder, dissector, scissors, or grasper.

27. The apparatus of claim 19 , further comprising a master console of the surgical robotic system, the master console disposed separately from the slave manipulator and including a first plurality of links that are configured to be operatively coupled to a second plurality of links of the slave manipulator to enable teleoperation of the slave manipulator by the master console,

wherein the restart is located on the master console proximate to or on the first plurality of links.

28. The apparatus of claim 27 , further comprising a sterile handle configured to be removably coupled to the master console,
