Real-time visual navigation system in minimally invasive orthopedic surgery based on virtual and real fusion

Abstract

The present invention provides a real-time visual navigation system in orthopedic minimally invasive surgery based on virtual and real fusion, including: NDI Polaris optical tracking device: used to obtain 6-degree-of-freedom position and posture information of marker points in real three-dimensional space; optical tracking device bracket: used To support the optical tracking device (NDIPolaris), the optical tracking device can be placed at the pointing position at any angle; depth camera: used to obtain video data and video depth information in the front and side directions during the operation; display: used for real-time display during the operation The position and posture of the tracked surgical instrument in the front side video, side video and 3D virtual model realize the "visualization" of minimally invasive surgery; video equipment bracket: used to support the depth camera and display equipment, and fix them in the designated position; The video navigation computing device is used to process the data acquired by the optical tracking device and the depth camera, and calculate and send the video navigation data to the display.

Description

technical field [0001] The invention relates to a real-time visual navigation system in orthopedic minimally invasive surgery based on virtual and real fusion. Background technique [0002] "Minimally invasive" is an inevitable trend in the development of orthopedic surgery, how to make minimally invasive surgery "precision" is an urgent problem to be solved. With the continuous development of virtual reality technology and augmented reality technology, their application in the medical field, especially in the field of minimally invasive orthopedics, has attracted more and more attention. Using virtual reality technology can break through the shackles of space, showing the patient's lesion area to the surgeon in all directions without dead ends; using enhanced display technology, digital virtual information can be superimposed on the real scene, fundamentally solving the non-intuitive orthopedic minimally invasive surgery , Inaccurate positioning and other issues.
