Systems and methods of controlling surgical robotic system using eye-tracking
A surgical robotic system includes at least one eye tracking system positioned detect the direction of at least one user's gaze. Input derived from the eye tracking system may be used to enter commands to the surgical robotic system depending on the directions of the gaze detected or other aspects of the gaze such as pupil dilation or speed of eye movement.
1. A surgical robotic system comprising:
a camera positionable at a surgical site within a body cavity to capture images of a surgical field;
at least one robotic arm configured to carry a surgical instrument, the surgical instrument maneuverable by the robotic system in accordance with input from a surgeon input device,
a camera display for displaying images of the surgical field captured by the camera, and
an eye tracking system positionable to detect the direction of a gaze of a user towards the camera display,
wherein the system is configured to distinguish blood vessels from surrounding tissue in the camera images and to, in response to detection of the user's gaze towards a blood vessel in an image that is displayed on the display, add indicia to the displayed camera images, the indicia overlaying a first region of the image comprising both a first portion at which the user's gaze meets the camera display and a second portion that is displayed on the camera display but is outside the first portion, to highlight a full length of the blood vessel visible on the camera display as said full length to differentiate said full length from the surrounding tissue.
2. The system of claim 1 , wherein the indicia are selected from indicia including shading, coloring, outlining, highlighting, text, graphics, or other images.
3. The system of claim 2 , wherein the system is configured to, in response to movement of the gaze to a second region on the display, adding indicia to the second region.
4. The system of claim 1 , wherein the indicia is added to the first region in response to detection of auxiliary input to the system.
5. The system of claim 4 , wherein the auxiliary input is selected from a group consisting of a visual cue, verbal command, button press, brain activity input or myoelectric input.
6. The system of claim 1 , wherein the indicia comprise text dictated by surgical personnel about the region.
7. A system comprising:
a camera positionable at a surgical site within a body cavity to capture images of the surgical site;
a display for displaying images of the surgical site captured by the camera; and
an eye tracking system positionable to detect the direction of a gaze of a user towards the display,
wherein the system is configured to distinguish blood vessels from surrounding tissue in the camera images and to, in response to detection of the user's gaze towards a blood vessel in an image that is displayed on the display, add indicia to the displayed camera images, the indicia overlaying a first region of the image comprising both a first portion at which the user's gaze meets the camera display and a second portion that is displayed on the camera display but is outside the first portion, to highlight a full length of the blood vessel visible on the camera display to differentiate said full length from the surrounding tissue.
8. The system of claim 7 , wherein the indicia is added to the first region in response to detection of auxiliary input to the system.
9. The system of claim 3 , wherein the indicia are selected from indicia including shading, coloring, outlining, highlighting, text, graphics, or other images.
10. The system of claim 7 , wherein the indicia comprise text dictated by surgical personnel about the region.
11. The system of claim 7 , wherein the auxiliary input is selected from a group consisting of a visual cue, verbal command, button press, brain activity input or myoelectric input.
