Interactive computer-assisted surgery system and method
View Patent ↗A system and method for providing computer assistance for performing a medical procedure provides a graphical user interface to guide and/or assist a user, for example a surgeon, performing the medical procedure, whether surgical or non-surgical. The computer-assisted system comprises a software application that may be used for a medical procedure.
1. An apparatus for a medical procedure comprising:
a memory which stores a series of interface images which assist a user with the medical procedure;
a display which displays a selected interface image;
a processor programmed to:
receive signals indicative of a location and an identity of a tool in a field of view of a tool tracking system,
based at least in part on the identity of the tool in the field of view, determine a stage of the medical procedure,
select one of said series of interface images in response to an occlusion from the tracking system of a predetermined portion of said tool by said user for a predetermined interval of time based on the determined stage of the medical procedure and the identity of the tool, and
cause the display to display the selected interface image with a location of the occluded tool remaining stationary.
2. The apparatus of claim 1 , wherein said processor is further programmed to control the display to display a dynamic bar indicating a time period remaining for completing a predefined task.
3. The apparatus of claim 1 , wherein the tool is a hand-held tool instrumented to (1) be tracked by the tracking system and (2) have an identity of the tool determined by the tracking system.
4. The apparatus of claim 3 , wherein said processor is further programmed to:
determine whether said tracking system has detected an additional tool;
determine which of said tool and said additional tool is closest to a predefined point; and
designate one of the tool and said additional tool as a dominant tool; and
cause the display of the location of the dominant tool.
5. The apparatus of claim 4 , wherein said processor is further programmed to automatically execute a command associated with said dominant tool.
6. The apparatus of claim 3 , wherein said processor is programmed to:
cause the display to display the selected one of said series of interface images in response to a predetermined portion of said tool being out of the field of view of said tracking system during a predetermined period of time.
7. An apparatus for a medical procedure comprising:
a memory which stores a series of interface images which assist a user with the medical procedure;
a display which displays a selected interface image;
a processor programmed to:
receive signals indicative of an identity of a tool in a field of view of a tool tracking system,
based at least in part on the identity of the tool in the field of view, determine a stage of the medical procedure,
select one of the series of interface images based on the determined stage of the medical procedure and the identity of the tool,
cause the display to display the selected interface image,
receive signals indicative of a location of the tool in the field of view of the tool tracking system,
determine whether the tool in the field of view of the tracking system is occluded,
determine how long the tool remains occluded, and
cause the display to display a visual indication of the occlusion, the visual indication of the occlusion including an occlusion meter.
8. The apparatus of claim 7 , wherein said processor is further programmed to cause the display to change a color of at least a portion of said occlusion meter upon occlusion of a predetermined portion of said tool, a length of said portion indicating an elapsed time since initiation of said occlusion.
9. The apparatus of claim 8 , wherein a length of a portion of said occlusion meter indicates how long the tool has been occluded from the tracking system.
10. The apparatus of claim 8 , wherein said processor is further programmed to control the display to revert the color of said portion of said occlusion meter to a color indicative of no occlusion upon termination of said occlusion.
11. The apparatus of claim 7 , wherein the tool is a hand-held tool instrumented to be optically tracked by the tracking system, the occlusion meter being indicative of a duration that the tool has been occluded from the tracking system by an intervening person or structure.
