Abstract

A video overlay device is provided for use in a surgical setting to overlay surgical parameters from a surgical console over images from a surgical microscope. The device includes a video input port configured to receive image data from a camera and a data port configured to accept a removable storage device storing encrypted WiFi configuration data. The device further includes a WiFi transceiver configured to connect to a local WiFi network hosted by the surgical console based on the encrypted WiFi configuration data and receive overlay data from the surgical console. The device further includes a processor configured to generate combined image data based on the image data and the overlay data, and a video output port configured to transmit the combined image data to a display.

Description

Video overlay system for surgical setup Cross Reference to Related Applications The present application claims the benefit and priority of U.S. provisional patent application No. 63/594,863 filed on month 31 of 2023, which is hereby assigned to the assignee of the present application and is hereby expressly incorporated by reference in its entirety for all applicable purposes as set forth more fully below. Background Typically, surgery (such as ophthalmic surgery) may be video recorded for documentation, research, learning, and/or teaching. For example, during cataract surgery, a camera and/or microscope may receive images similar to the surgeon's view of the surgical field. Current techniques for cataract surgery include the use of ultrasonic energy in various modalities, variable level vacuum, fluid infusion, and other variables that affect the surgery and represent different surgical techniques. These techniques and parameters are of interest for surgery, and the surgeon may wish to provide these parameters to the display in real-time with video signals from the camera and/or microscope for recording, for training purposes, and/or for documentation. Some data related to the parameters may remain constant during the surgical procedure, while other data will change as the surgeon selects different settings during the surgical procedure. Specialized video overlay systems have been developed to perform the act of overlaying images representing various parameters onto video signals captured from surgery. Operation of a video overlay system typically requires physical connection to a surgical console via a cable that transmits data to create a graphical representation of the data at the video overlay system. The video signal is similarly input into the video overlay system. The processed video output signal output from the video overlay system contains the video image as a background and an overlay portion displaying parameters from the surgical console. Some existing video overlay systems typically require a physical connection via a data cable between the surgical console and the video overlay system to transfer data between the surgical console and the video overlay system. In some other existing video overlay systems that do not require a physical connection between the video overlay system and the surgical console, there may be security issues related to the shared WiFi (wireless fidelity) network and password information used to configure the video overlay system to connect wirelessly to the surgical console. Disclosure of Invention Aspects of the present disclosure relate to a video overlay system for use in a surgical setting, and more particularly, to a video overlay device operable to overlay surgical parameters from a surgical console over images from a surgical microscope. In certain embodiments, an apparatus is provided. The device includes a video input port configured to receive image data from a camera and a data port configured to accept a removable storage device storing encrypted WiFi configuration data. The device further includes a WiFi transceiver configured to connect to a local WiFi network hosted by the surgical console based on the encrypted WiFi configuration data and receive overlay data from the surgical console. The device further includes a processor configured to generate combined image data based on the image data and the overlay data, and a video output port configured to transmit the combined image data to a display. In some embodiments, a method for generating video overlay data is provided. The method includes receiving image data from a camera at a video input port and reading encrypted WiFi configuration data stored on a removable storage device at a data port. The method further includes connecting, via the WiFi transceiver, to a local WiFi network hosted by the surgical console based on the encrypted WiFi configuration data, and receiving, via the WiFi transceiver, overlay data from the surgical console. The method further includes generating, at the processor, combined image data based on the image data and the overlay data, and transmitting the combined image data to the display through the video output port.
