Abstract

The invention provides a real-time visual navigation system in orthopaedic minimally invasive surgery based on virtual-real fusion. The real-time visual navigation system based on virtual-real fusioncomprises an NDIPolaris optical tracking device, a virtual-real fusion device and a navigation device, wherein the NDIPolaris optical tracking device is used for acquiring six-degree-of-freedom pose information of a mark point in a real three-dimensional space; an optical tracking equipment bracket used for supporting optical tracking equipment (NDIPolaris) so that the optical tracking equipment is placed at a pointing position at any angle; a depth camera used for acquiring video data and video depth information in normal and lateral directions in an operation; a display used for displaying the poses of the tracked surgical instrument in the front side video, the side video and the three-dimensional virtual model in real time so as to realize visualization of the minimally invasive surgery; a video equipment bracket used for supporting the depth camera and the display equipment and fixing the depth camera and the display equipment at specified positions; and a video navigation calculation device is used for processing data acquired by the optical tracking equipment and the depth camera, calculating video navigation data and sending 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.
