Surgical imaging device
First Claim
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.

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.

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. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)
