Patent number: 10580217Abstract: An augmented reality surgical system includes a head mounted display (HMD) with a see-through display screen, a motion sensor, a camera, and computer equipment. The motion sensor outputs a head motion signal indicating measured movement of the HMD. The computer equipment computes the relative location and orientation of reference markers connected to the HMD and to the patient based on processing a video signal from the camera. The computer equipment generates a three dimensional anatomical model using patient data created by medical imaging equipment, and rotates and scales at least a portion of the three dimensional anatomical model based on the relative location and orientation of the reference markers, and further rotate at least a portion of the three dimensional anatomical model based on the head motion signal to track measured movement of the HMD. The rotated and scaled three dimensional anatomical model is displayed on the display screen.Type: GrantFiled: June 5, 2018Date of Patent: March 3, 2020Assignee: Globus Medical, Inc.Inventors: Kenneth Milton Jones, John Popoolapade, Thomas Calloway, Thierry Lemoine, Christian Jutteau, Christophe Bruzy, Yannick James, Joachim Laguarda, Dong-Mei Pei Xing, Sebastien Gorges, Paul Michael Yarin
