A patent has been issued for a system and method that enables real-time visual examination of in vivo tissues and selective display of luminal networks beneath the surface of the tissues being examined. The patent, filed by inventors Komp and Sartor and assigned to Covidien LP, involves imaging tissue by receiving white light and near infrared images, detecting fluorescence, and generating composite images for display in a user interface. The system includes an endoscope with white light and near infrared sources, a camera, a processor, and a display, allowing for the identification of luminal networks such as blood vessels or lymphatic ducts.

Cilag GmbH International has been issued a patent for a computing system that can use redundant communication pathways to obtain and display surgical video streams. The system can detect issues with the video stream being displayed and switch to another stream if necessary. It can also generate a composite video stream by overlaying content associated with the surgical procedure onto the surgical video stream. The system can determine the overlay region location, size, and orientation based on markers or fiducial markers captured in the video frames. This technology aims to improve the delivery and processing of surgical video feeds. [Extracted from the article]

The method of claim 9, wherein the plurality of surgical video streams comprises a third surgical video stream, and wherein the method further comprises enhancing the first surgical video stream using the third surgical video stream prior to sending the first surgical video stream for display. The method of claim 9, wherein the first surgical video stream and the second surgical video stream are associated with imaging data captured via a same light sensing element and, the first surgical video stream and the second surgical video stream are processed via different processing modules. The method of claim 9, further comprising: processing the first surgical video stream using the first processing module; processing the second surgical video stream using the second processing module; and merging the processed first surgical video stream and the processed second surgical video stream, upon detecting the issue associated with the first processing module, suspending merging the processed first surgical video stream and the processed second surgical video stream.

The method of claim 11, wherein the plurality of surgical video streams comprises a third surgical video stream, and wherein the method further comprises enhancing the first surgical video stream using the third surgical video stream prior to sending the first surgical video stream for display. The method of claim 11, further comprising: processing the first surgical video stream using the first processing module; processing the second surgical video stream using the second processing module; and merging the processed first surgical video stream and the processed second surgical video stream, upon detecting the issue associated with the first processing module, suspending merging the processed first surgical video stream and the processed second surgical video stream. The method of claim 11, wherein the first surgical video stream and the second surgical video stream are associated with imaging data captured via a same light sensing element and, the first surgical video stream and the second surgical video stream are processed via different processing modules.

Upon detecting an issue with the video stream being displayed, the computing system may display another obtained surgical video stream or send another obtained surgical video stream for display. The computing system of claim 1, wherein processor is further configured to: identify a fiducial marker in the first frame of the video stream; determine an orientation of the fiducial marker in the first frame; determine a first overlay orientation for overlaying the overlay content onto the first frame based on the orientation of the fiducial marker in the first frame; identify the fiducial marker in the second frame of the video stream; determine an orientation of the fiducial marker in the second frame; and determine a second overlay orientation for overlaying the overlay content onto the second frame based on the orientation of the fiducial marker m the second frame. The computing system of claim 1, wherein the overlay content comprises a secondary surgical video stream associated with the surgical procedure, and processor is further configured to: extract a portion of the secondary surgical video stream that comprises a region of interest; overlay the portion of the secondary surgical video stream onto the first frame of the surgical video stream at the determined first overlay region location; and overlay the portion of the secondary surgical video stream onto the second frame of the surgical video stream at the determined second overlay region location.
