Abstract

A visualization instrument comprising a display support component removably coupled to a component insertable into a target space. The insertable component includes a camera providing images of the target space. The images are presented in a display device supported by the display support component. The insertable component may be discarded after a permitted number of uses.

Claims

1. A visualization instrument comprising:

a reusable portion including a display device, a processing device, and an energy source housing adapted to receive a self-contained energy source configured to power the display device and the processing device;

a camera including an imaging sensor, the camera outputting an image stream corresponding to a plurality of views obtained through the lens and electronically coupled to the display device to present images corresponding to the plurality of views with the display device;

an integrally formed single-piece blade including a handle portion and an insertable portion adjacent the handle portion, the handle portion including a proximal cavity configured to detachably receive the energy source housing and to support the display device and the processing device when the energy source housing is received in the proximal cavity, the blade thus detachably coupled to the reusable portion, the insertable portion insertable into a patient; and

a camera identifier, a data storage device, and a plurality of camera identifiers stored in the data storage device, wherein the processing device compares the camera identifier to the plurality of camera identifiers to find a match and disables presentation of the images if the match is not found.

2. A visualization instrument as in claim 1, the visualization instrument further comprising:

a use indicia; and

a sensing device electronically coupled to the processing device and sensing the use indicia, the processing device cooperating with the use indicia to determine a number of uses of the blade and to disable presentation of the images after the insertable portion has been used a permitted number of uses.

3. The visualization instrument of claim 2, wherein the permitted number of uses is one.

4. A visualization instrument as in claim 1, further comprising:

a sensing device electronically coupled to the processing device and sensing environmental variables including at least one of temperature and humidity, wherein the visualization instrument is operable to track a number of uses of the blade based on status changes of the environmental variables, each status change comprising an environmental variable exceeding a threshold for a predetermined amount of time.

5. The visualization instrument of claim 2, wherein the use indicia comprises a single-use fuse.

6. The visualization instrument of claim 2, further comprising an image sensor identifier, wherein the processing device determines the number of uses based on the image sensor identifier.

7. The visualization instrument of claim 6, wherein the image sensor identifier is stored in the camera.

8. The visualization instrument of claim 6, further comprising an electronic device storing the image sensor identifier, the electronic device supported by one of the handle portion and the insertable portion and electronically coupled to the processing device when the insertable portion is coupled to the display device.

9. The visualization instrument of claim 1, wherein the visualization instrument is adapted to intubate a patient with a tube, wherein the tube is distinguishable in the images presented with the display device as the tube passes through a field of view of the lens.

10. The visualization instrument of claim 1, wherein the visualization instrument is adapted to intubate the patient with a tube, the blade further comprising at least two guide surfaces defining a guide pathway having an open side configured to enable removal of the tube.

11. A visualization instrument as in claim 1, the visualization instrument further comprising:

tracking means for disabling presentation of the corresponding images after the insertable portion has been used a permitted number of uses, wherein the tracking means comprises a sensing device and a use indicia, the sensing device sensing the use indicia to determine a number of uses of the blade, the processing device cooperating with the tracking means to determine if the insertable portion has been used more than the permitted number of uses.

12. The visualization instrument of claim 11, wherein the tracking means comprises a single-use fuse.

13. The visualization instrument of claim 11, wherein the permitted number of uses is one.

14. The visualization instrument of claim 11, wherein the tracking means is operable to track when the insertable portion is used by evaluating environmental variables including at least one of temperature and humidity.

15. The visualization instrument of claim 11, wherein the tracking means comprises an identification feature configured to track the number of uses.

16. The visualization instrument of claim 15, wherein the identification feature is a camera identifier.

17. The visualization instrument of claim 2, wherein the use indicia comprises an identification feature detectable in the image stream.

18. The visualization instrument of claim 1, further comprising an identification component, wherein the processing device determines the number of uses based on the identification component.

19. The visualization instrument of claim 18, wherein the identification component is a unique feature detectable in the image stream.

20. The visualization instrument of claim 18, wherein the identification component is an electronic identifier.

21. The visualization instrument of claim 20, wherein the electronic identifier is a programmable identifier located in an integrated circuit in the insertable portion.

22. The visualization instrument of claim 18, wherein the identification component is a physical mark in the insertable portion.

23. The visualization instrument of claim 11, wherein the tracking means comprises an identification component, and the processing device is configured to determine a number of uses based on the identification component.

24. The visualization instrument of claim 23, wherein the identification component is a unique feature detectable in the image stream.

25. The visualization instrument of claim 23, wherein the identification component is an electronic identifier.

26. The visualization instrument of claim 25, wherein the electronic identifier is a programmable identifier located in an integrated circuit in the insertable portion.

27. The visualization instrument of claim 23, wherein the identification component is a physical mark in the insertable portion.
