Abstract

A foot pedal assembly for controlling a robotic surgical system includes a foot pedal assembly base including an axle, a foot pedal slidably and pivotally coupled to the axle, and a sensor arrangement configured to detect an axial position of the foot pedal along the axle and a pivoted position of the foot pedal around the axle. Different combinations of different detected axial positions and detected pivoted positions are correlateable to different functions of the robotic surgical system.

First claim

The invention claimed is:

1. A foot pedal assembly for controlling a robotic surgical system, comprising:
a foot pedal assembly base;
a foot pedal translatably and pivotally coupled to the foot pedal assembly base; and
a sensor arrangement configured to detect an axial position of the foot pedal along the foot pedal assembly base and a pivoted position of the foot pedal relative to the foot pedal assembly base,
wherein different combinations of different detected axial positions and detected pivoted positions are correlateable to different functions of the robotic surgical system.

2. The foot pedal assembly of claim 1 , wherein the foot pedal assembly base comprises a horizontal axle that runs parallel to a surface of the foot pedal assembly, and the foot pedal translates and pivots about the horizontal axle.

3. The foot pedal assembly of claim 1 , wherein the detected axial position is correlateable to control of a user-selected instrument.

4. The foot pedal assembly of claim 3 , wherein the detected pivoted position is correlateable to control of a function of the user-selected instrument.

5. The foot pedal assembly of claim 4 , wherein the foot pedal is translatable between a first axial position and a second axial position, and pivotable between a first pivoted position and a second pivoted position.

6. The foot pedal assembly of claim 5 , wherein the foot pedal is bi-stable between the first and second axial positions.

7. The foot pedal assembly of claim 5 , wherein the foot pedal further comprises a third axial position between the first and second axial positions, wherein the third axial position corresponds to a safety lock-out function of the robotic surgical system.

8. The foot pedal assembly of claim 7 , further comprising at least one biasing element urging the foot pedal to the third axial position.

9. The foot pedal assembly of claim 5 , further comprising at least one biasing element urging the foot pedal to a third pivoted position between the first and second pivoted positions.

10. The foot pedal assembly of claim 1 , further comprising an intermediate component slidably engaged with the foot pedal assembly base and comprising an axle, and the foot pedal is pivotally coupled to the axle.

11. The foot pedal assembly of claim 10 , wherein a motion of the intermediate component relative to the foot pedal assembly base provides a translational range of motion of the foot pedal relative to the foot pedal assembly base.

12. The foot pedal assembly of claim 10 , further comprising a track coupled to the foot pedal assembly base and a carriage that moves along the track in an axial direction, and the intermediate component is coupled to the carriage such that the intermediate component travels relative to the foot pedal assembly base along the track.

13. The foot pedal assembly of claim 1 , wherein the foot pedal is pivotally coupled to the axle at a location farther from a first foot pedal end than a second foot pedal end opposite the first pedal end.

14. The foot pedal assembly of claim 1 , wherein the sensor arrangements comprise one or more switches.

15. The foot pedal assembly of claim 1 , wherein the foot pedal assembly base or the intermediate component comprises an axle, and the foot pedal is coupled to the axle such that the axle is farther from a first foot pedal end than from a second foot pedal end opposite the first foot pedal end.

16. The foot pedal assembly of claim 15 , wherein the foot pedal comprises a positional reference located farther from the first pedal end than from the second pedal end.

17. The foot pedal assembly of claim 1 , further comprising a second foot pedal assembly base and a second foot pedal pivotally and axially coupled to the foot pedal assembly base.
