Granted
Collaborative mixed-reality system for immersive surgical telementoring
US12482192B2 · Granted November 25, 2025Systems and methods using mixed reality to enable remotely located expert surgeons to instruct novice surgeons as if they were together in the same operating room. A VR display shows a 3D virtual reconstruction of the patient to the remote expert, while an AR display shows the expert's hand gestures spatially aligned with the patient for the on-site surgeon.
