Abstract

A surgical imaging device includes at least one light source for illuminating an object, at least two image sensors configured to generate image data corresponding to the object in the form of an image frame, and a video processor configured to receive from each image sensor the image data corresponding to the image frames and to process the image data so as to generate a composite image. The video processor may be configured to normalize, stabilize, orient and/or stitch the image data received from each image sensor so as to generate the composite image. Preferably, the video processor stitches the image data received from each image sensor by processing a portion of image data received from one image sensor that overlaps with a portion of image data received from another image sensor. Alternatively, the surgical device may be, e.g., a circular stapler, that includes a first part, e.g., a DLU portion, having an image sensor a second part, e.g., an anvil portion, that is moveable relative to the first part. The second part includes an arrangement, e.g., a bore extending therethrough, for conveying the image to the image sensor. The arrangement enables the image to be received by the image sensor without removing the surgical device from the surgical site.

Claims

1. A surgical imaging device, comprising:

at least one light source for illuminating an object;

at least two image sensors, each image sensor configured to generate image data corresponding to the object in the form of an image frame, each image frame partially overlapping with at least one other image frame, each of the image sensors corresponding to a different point of view with respect to the object; and

a video processor configured to receive simultaneously from each image sensor the image data corresponding to the image frames and to process the image data by combining the image frames to generate a composite image from the combined image frames, each image frame corresponding to a subportion of the composite image,

wherein the at least two image sensors are positioned opposite from one another such that the composite image is generated therebetween and each opposing image sensor is angled towards its respective point of view to generate the composite image between the at least two opposing image sensors.

2. The device of claim 1, wherein the surgical imaging device is configured to be inserted into a body of a patient.

3. The device of claim 2, wherein the video processor stitches the image data received from each image sensor by processing a portion of image data received from one image sensor that overlaps with a portion of image data received from another image sensor.

4. The device of claim 1, wherein the surgical imaging device is configured to be inserted into an abdominal cavity of a patient.

5. The device of claim 1, wherein the composite image corresponds to an entire abdominal cavity of a patient.

6. The device of claim 1, wherein the video processor is configured to normalize the image data received from each image sensor.

7. The device of claim 1, wherein the video processor is configured to orient the image data received from each image sensor.

8. The device of claim 1, wherein the video processor is configured to stitch the image data received from each image sensor so as to generate the composite image.

9. The device of claim 1, wherein the video processor is configured to one of establish or adjust orientation data points of the composite image.

10. The device of claim 9, wherein the video processor one of establishes or adjusts orientation data points of the composite image by a control device that moves one or more of the image sensors.

11. The device of claim 1, wherein the video processor is configured to selectively generate a region of interest corresponding to a portion of the composite image.

12. The device of claim 11, wherein the video processor selectively generates the region of interest corresponding to a portion of the composite image in accordance with signals received from a control device.

13. The device of claim 11, wherein the video processor is configured to automatically adjust the region of interest.

14. The device of claim 13, wherein the video processor automatically adjusts the region of interest so as to continuously display a surgical instrument as the surgical instrument is moved.

15. The device of claim 1, wherein the video processor is configured to selectively generate a region of interest corresponding to signals received from a user input device to zoom into or out of a portion of the composite image.

16. The device of claim 1, further comprising a display device coupled to the video processor, the video processor configured to generates a display image for display on the display device.

17. The device of claim 16, wherein the display device is a wireless personal display monitor.

18. The device of claim 16, wherein the display device is an overhead display monitor.

19. The device of claim 1, wherein the composite image has an aspect ratio of 16:

9.

20. The device of claim 1, wherein the composite image has an aspect ratio of 4:

3.

21. A method for generating an image comprising the steps of:

illuminating an object in a surgical site;

simultaneously generating, via at least two image sensors, at least two sets of image data corresponding to the object, each of the image sensors corresponding to a different point of view, each set of image data partially overlapping at least one other set of image data, wherein the at least two image sensors are positioned opposite from one another such that the composite image is generated therebetween and each opposing image sensor is angled towards its respective point of view to generate the composite image between the at least two opposing image sensors; and

combining the at least two sets of image data so as to generate a composite image from the combined image data, each set of image data corresponding to a subportion of the composite image.

22. The method of claim 21, further comprising the step of generating the image inside a body of a patient.

23. The method of claim 21, further comprising the step of inserting the surgical imaging device into an abdominal cavity of a patient.

24. The method of claim 23, wherein the processing step includes generating the composite image of an entire abdominal cavity of a patient.

25. The method of claim 21, further comprising the step of normalizing the image data received from each image sensor.

26. The method of claim 21, further comprising the step of orienting the image data received from each image sensor.

27. The method of claim 21, further comprising the step of stitching the image data received from each image sensor so as to generate the composite image.

28. The method of claim 27, wherein the stitching includes processing a portion of image data received from one image sensor that overlaps with a portion of image data received from another image sensor.
