Abstract
Described herein is a teleoperational medical system for performing a medical procedure in a surgical field. The teleoperational system comprises an eye tracking unit and a control unit. The eye tracking unit includes an image display configured to display to a user an image of the surgical field, at least one eye tracker configured to measure data about a gaze point of the user, and a processor configured to process the data to determine a viewing location in the displayed image at which the gaze point of the user is directed. The control unit is configured to control at least one function of the teleoperational medical system based upon the determined viewing location.
Claims58
A teleoperational medical system for performing a medical procedure in a surgical field, the system comprising:
- an eye tracking unit including:
- an image display configured to display to a user an image of the surgical field;
- at least one eye tracker configured to measure data about a gaze point of the user;
- a processor configured to process the data to determine a viewing location in the displayed image at which the gaze point of the user is directed;
- and
- a control unit configured to control at least one function of the teleoperational medical system based upon the determined viewing location.
A method for operating a teleoperational medical system, the method comprising:
- displaying an image, including a surgical field image of a surgical field, on an image display;
- measuring a gaze point of a user in the image display;
- determining a viewing location in the displayed image at which the gaze point of the user is directed;
- and
- controlling at least one function of the teleoperational medical system based upon the determined viewing location.
A teleoperational medical system for performing a medical procedure in a surgical field, the surgical system comprising:
- an eye tracking unit including:
- an image display configured to display to a user an image of the surgical field;
- at least one eye tracker configured to measure data about a gaze point of the user;
- a processor configured to process the data to determine a viewing location in the displayed image at which the gaze point of the user is directed;
- a control unit configured to control at least one function of the teleoperational medical system based upon the determined viewing location;
- and
- a surgical instrument, wherein the control unit is configured to control at least one function of the surgical instrument in the surgical field based upon the determined viewing location in the displayed image, and wherein the control unit is configured to activate the surgical instrument if the processor determines that the viewing location matches a position of the surgical instrument in the image display for a predetermined length of time.
