20220233244 | AUDIO AUGMENTED REALITY CUES TO FOCUS ON AUDIBLE INFORMATION - An audible augmented reality (AR) computing system may receive audio data such as audible information, from a sensing system in an operating room (OR), ambient noise in the OR. The audio AR computing system may generate AR content. For example, the audio AR computing system may generate AR content based on the audible data. The AR content may be or may include audible information associated with the audio data. The audio AR computing system may receive an adjustment indication. The adjustment indication may be or may include one or more of adjustment information for the AR content. For example, the adjustment indication may be or may include one or more of a surgical task indication, a task importance indication, an audio insertion indication, an audio translation indication, an audio source location indication. The audio AR computing system may adjust the AR content based on the received adjustment indication. | 2022-07-28 |
20220233245 | MEDICAL CONTROL DEVICE AND MEDICAL OBSERVATION SYSTEM - A medical control device includes: determination circuitry configured to determine whether or not a specific surgical tool is included in a captured image based on an image signal generated by an imaging device configured to capture an image of a subject eye; image generation circuitry configured to generate an image for display based on the image signal; and a state controller configured to control, in a case where the determination circuitry determines that the specific surgical tool is not included in the captured image, operation of the image generation circuitry or an imaging field of view by the imaging device so as to maintain a state of the subject eye in the image for display. | 2022-07-28 |
20220233246 | Fiber Optic Shape Sensing System Associated With Port Placement - Disclosed herein is a system and method directed to placing a first medical instrument in a patient body, where the system includes the first medical instrument being an implantable medical instrument, a second medical instrument comprising an optical fiber having one or more of core fibers, and a console having stored thereon logic that, when executed, causes operations including providing an incident light signal to the optical fiber, receiving reflected light signals, processing the reflected light signals, and determining (i) a shape of the second medical instrument within the patient body, and (ii) a shape of the first medical instrument within the patient body based on the shape of the second medical instrument. | 2022-07-28 |
20220233247 | SYSTEM AND METHOD FOR TRACKING POSITIONING OF MEDICAL INSTRUMENT BY USING AUGMENTED REALITY - A medical instrument positioning tracking system according to the present invention comprises: a bar-type medical instrument of which the front end part is formed in a bar shape including needle and syringe shapes and which has an identification segment formed, on the rear end part thereof, in the longitudinal direction of the bar shape; a tracking multi-camera including a plurality of cameras provided at a plurality of locations so that the identification segment can be photographed in a plurality of time points; a display device for displaying an augmented reality image with the bar-type medical instrument as an augmented object and also displaying relevant information including location and angle information of the bar-type medical instrument; and a control device for acquiring, in real time, a tracking image capture by the tracking multi-camera for every frame, estimating a three-dimensional segment by using the acquired image, estimating the actual three-dimensional positioning of the bar-type medical instrument by using the location relationship between a pre-measured location of the bar-type medical instrument and the three-dimensional segment, and displaying, as an augmented reality image, the estimated three-dimensional positioning information including the location and angle information of the bar-type medical instrument on the display device. | 2022-07-28 |
