Abstract

Systems, methods and apparatus are disclosed for improving medical procedures and medical procedure management, and, more particularly, for tracking medical instruments throughout a procedure and assisting medical personnel throughout the procedure or at least at the conclusion of the procedure. In one form, an apparatus for tracking medical instruments throughout a procedure is disclosed having a single camera for tracking movement and/or detecting position of a plurality of medical instruments during a medical procedure as at least one of the plurality of medical instruments is moved between multiple zones at least including a first prep zone and a second procedure zone. The apparatus having a controller connected to and collecting images from the camera, and a display in electrical communication with the controller and/or the camera for displaying medical instrument data pertaining to the movement and/or position of the plurality of medical instruments.

First claim

What is claimed is:

1. An apparatus for tracking medical instruments throughout a procedure comprising:
a mobile cart movable about a room or from room to room and having a support extending therefrom;
a single camera for tracking movement and detecting position of a plurality of medical instruments during a medical procedure as at least one of the plurality of medical instruments is moved between multiple zones at least including a prep zone and a procedure zone, the single camera being mounted to the support extending from the mobile cart;
a controller connected to and collecting images from the camera;
a display in electrical communication with the controller and/or the camera for displaying medical instrument data pertaining to the movement and/or position of the plurality of medical instruments; and
wherein the plurality of medical instruments each have an instrument marker and the controller is capable of tracking movement and detecting position of the plurality of medical instruments from their respective instrument markers, the instrument marker is a two-dimensional (2D) barcode or a three-dimensional (3D) barcode machine readable by the controller via the camera from first and second angles without the need to move the camera and with the first and second angles being greater than thirty degrees (30°) apart.

2. The apparatus of claim 1 wherein the instrument markers include a machine readable marking comprising:
the two-dimensional (2D) barcode or the three-dimensional (3D) barcode and
an easy coding scheme that is readily identifiable by a human for redundant checking purposes so that a manual check can be performed in addition to an automated check conducted by the controller to ensure that none of the plurality of medical instruments are left behind during the conclusion of the medical procedure.

3. The apparatus of claim 1 wherein the instrument marker, camera and controller interact as an orientation agnostic system that is capable of tracking movement and/or detecting position of the plurality of medical instruments via the instrument marker regardless of what orientation or position each medical instrument or instrument marker is in at any given time without the need to move the camera.

4. The apparatus of claim 1 wherein the instrument marker is hydrophobic to improve machine readability of the instrument marker.

5. The apparatus of claim 1 wherein the instrument marker is formed on the medical instrument via etching, engraving, embossing, carving, molding, stamping, pressing, painting, printing, or vapor deposition.

6. The apparatus of claim 1 further including machine detectable zone markers for delineating the physical zones.

7. The apparatus of claim 6 wherein the machine detectable zone markers have first and second sides, with machine readable information on the first side and a fastener on the second side for fastening the machine detectable zone markers to a surface, the fastener including at least one of:
an adhesive;
a hook or loop fastener portion;
a clasp or clamp;
a zipper; and/or
a thread.

8. The apparatus of claim 7 wherein the machine detectable zone markers are adhesive labels with the two-dimensional (2D) barcode or a three-dimensional (3D) barcode on the first side and adhesive on the second side for adhering the label to a surface to form a zone delineator.

9. The apparatus of claim 8 wherein the zone markers are formed on medical drapes or coverings for at least one of a surgical instrument table, patient, operating table or patient support, surgical equipment, and/or waste container, all of which are within a viewing area of the camera mounted on the support extending from the mobile cart.

10. The apparatus of claim 6 wherein the physical zones further include a discard zone which is delineated by the machine detectable zone markers.

11. The apparatus of claim 1 wherein the camera both continually tracks movement and detects position of the plurality of medical instruments and the display displays specific data pertaining to both the spatial movement and position of the plurality of medical instruments.

12. The apparatus of claim 11 wherein the specific data pertaining to spatial movement includes tracking at least two of a x coordinate, a y coordinate and/or a z coordinate of the at least one of the plurality of medical instruments and the specific data pertaining to location includes an identification of what zone the at least one of the plurality of medical instruments is currently located.

13. The apparatus of claim 1 wherein the controller uses the camera to track medical instrument data including one or more of location, velocity or speed of travel, vector or direction of travel, and/or telemetry.

14. The apparatus of claim 1 wherein the apparatus includes a user interface for locating a missing medical instrument from the plurality of medical instruments.

15. The apparatus of claim 14 wherein the user interface is at least one graphical user interface located on the display that, when actuated, the controller displays on the display an image or video of the missing medical instrument prior to the missing medical instrument going missing to assist with locating the missing medical instrument.

16. The apparatus of claim 15 wherein the controller is configured such that a single actuation of the at least one graphical user interface allows video of the missing medical instrument to be pulled-up on the display and queued up to a period of time at or near when the missing medical instrument went missing which a user can review and replay as desired.

17. An apparatus for tracking medical instruments throughout a procedure comprising:
a mobile cart movable about a room or from room to room and having a support extending therefrom;
a camera mounted to the support extending from the mobile cart for tracking movement and detecting position of a plurality of medical instruments during a medical procedure as at least one of the plurality of medical instruments is moved between multiple zones at least including a prep zone and a procedure zone;
a controller connected to and collecting images from the camera; and
a display in electrical communication with the controller or the camera for displaying medical instrument data pertaining to the movement and/or position of the plurality of medical instruments including an image or video of any missing medical instrument prior to the missing medical instrument going missing to assist with locating the missing medical instrument; and
wherein the controller uses the camera to track medical instrument data including one or more of location, velocity or speed of travel, vector or direction of travel, and/or telemetry of each medical instrument without the need to move the camera.

18. The apparatus of claim 17 further comprising at least one graphical user interface located on the display that, when actuated, the controller displays on the display the image or video of the missing medical instrument prior to the missing medical instrument going missing to assist with locating the missing medical instrument.

19. The apparatus of claim 18 wherein the controller is configured such that a single actuation of the at least one graphical user interface allows video of the missing medical instrument to be pulled-up on the display and queued up to a period of time at or near when the missing medical instrument went missing which a user can review and replay as desired.

20. The apparatus of claim 17 further including an alarm for
