  • Method and apparatus for surgical procedure simulation based on virtual reality
    Patent number: 12376906
    Abstract: A method and apparatus for a surgical procedure simulation based on virtual reality (VR) are provided. The method includes generating a virtual three-dimensional (3D) body model corresponding to a body part of a subject of a surgical procedure based on a computed tomography (CT) image and providing a surgical procedure simulation for spinal cord stimulation based on the virtual 3D body model. The providing of the surgical procedure simulation for spinal cord stimulation includes outputting a virtual screen including the virtual 3D body model and a virtual C-arm apparatus, providing a surgical procedure simulation of loss of resistance (LOR) according to a selection of a user wearing the surgical procedure simulation apparatus within the virtual screen, and providing, when the surgical procedure simulation of LOR is completed, a surgical procedure simulation for lead insertion into a virtual spinal cord part included in the virtual 3D body model.
