20220039902 | SYSTEM AND METHOD FOR ENHANCED DATA ANALYSIS WITH SPECIALIZED VIDEO ENABLED SOFTWARE TOOLS FOR MEDICAL ENVIRONMENTS - Medical software tools platforms utilize a surgical display to provide access to specific medical software tools, such as medically-oriented applications or widgets, that can assist surgeons or surgical team in performing various procedures. In particular, an endoscopic camera may register the momentary rise in the optical signature reflected from a tissue surface and in turn transmit it to a medical image processing system which can also receive patient heart rate data and display relevant anomalies. Changes in various spectral components and the speed at which they change in relation to a source of stimulus (heartbeat, breathing, light source modulation, etc.) may indicate the arrival of blood, contrast agents or oxygen absorption. Combinations of these may indicate various states of differing disease or margins of tumors, and so forth. Also, changes in temperatures, physical dimensions, pressures, photoacoustic pressures and the rate of change may indicate tissue anomalies in comparison to historic values. | 2022-02-10 |

20220039904 | JIG ASSEMBLED ON STEREOSCOPIC SURGICAL MICROSCOPE FOR APPLYING AUGMENTED REALITY TECHNIQUES TO SURGICAL PROCEDURES - A system includes a first optical assembly (OA), a second OA and a processor. The first OA and second OA each coupled with a first and second microscope eyepiece, respectively. Each first and second OAs including a light source, configured to direct an emitted light beam (ELB) through the microscope toward an organ, and an image sensor, configured to sense a reflected light beam (RLB), which is reflected from the organ through the microscope, and to produce a signal indicative of the RLB. The processor is configured to control the first and second OAs to alternately direct the ELB and sense the RLB at first and second time intervals, and alternately display on a first display, during the first time intervals, images based on the signal from the first OA, and display on a second display, during the second time intervals, images based on the signal from the second OA. | 2022-02-10 |
20220039905 | MEDICAL CONTROL SYSTEM AND METHOD THAT USES PACKETIZED DATA TO CONVEY MEDICAL VIDEO INFORMATION - Provided is a medical control apparatus including: a processing unit configured to cause one or both of a first display region in which an object relating to an input source of an image is to be displayed and a second display region in which an object relating to an output destination of an image is to be displayed and a third display region in which an object for controlling the input source or the output destination is to be displayed, to be displayed in one screen. | 2022-02-10 |
20220039906 | NANOFIBER ADHESIVES FOR NAVIGATION TRACKER FIXATION - A tracker system for use in image guided surgery is disclosed. The tracker system may couple to wet tissue and may include a navigation tracker and a base pad that couple to each other. The base pad may be fabricated from a plurality of nonwoven nanofibers. The base pad is configured to couple to body tissue of a patient via at least one of adsorption, hydration equilibrium, and macromolecular interpenetration. | 2022-02-10 |
20220039907 | Inhibiting Post-Biopsy Inflammation and Metastasis - A method of inhibiting cancer cell metastasis in a subject by providing a biopsy marker device constructed of a polymeric material, the polymeric material containing an anti-inflammatory agent which is releasable over an extended period of time from the polymeric material after the biopsy marker device has been implanted in a tissue of the subject, and implanting the biopsy marker device into a tissue cavity of the subject, wherein the tissue cavity is caused by a biopsy performed on a tumor in the subject, and wherein release of the anti-inflammatory agent from the polymeric material does not begin for at least 18 to 24 hours after implantation and continues for at least 14 to 60 days after implantation. Metastasis of cancer cells from the tissue cavity is inhibited when the tumor is cancerous. The tissue may be, for example, breast, lung, prostate, pancreas, liver, kidney, uterus, ovary, intestine, stomach, or neck tissue. | 2022-02-10 |
20220039908 | DATA ANALYTICS AND INTERFACE PLATFORM FOR PORTABLE SURGICAL ENCLOSURE - Provided herein is a portable surgical system designed for interoperability with surgical or research tools and processes. The portable surgical system may comprise a portable enclosure and one or more sensors. Also provided herein are methods for training surgery robots for use with the system and manufacturing the portable surgical system. | 2022-02-10 |
