Mobile terminal-based anterior cruciate ligament reconstruction surgical navigation method and system

Abstract

The invention aims to provide an anterior cruciate ligament reconstruction surgical navigation method and system, and the method comprises the steps: carrying out the three-dimensional reconstruction of a virtual model of an affected part of a patient through a preoperative segmentation and modeling module, and setting a reference point in the virtual model; acquiring real operation scene information, and calculating position coordinates of a marker on a patient through a camera calibration and video acquisition module; carrying out space registration on the virtual model and a real surgical site by utilizing a virtual-real registration technology module, configuring a surgical planning path on a display, and carrying out navigation; and displaying a real surgical imaging result through an imaging and position tracking module, tracking the marker in real time and calculating coordinate information of the marker so as to complete surgical navigation for anterior cruciate ligament reconstruction. The point-to-point registration is adopted to automatically complete the registration of the virtual scene and the real scene, when the registration of the reference point is inaccurate, the registration of the reference point can be manually completed through the position information fed back in real time, and the registration rate is improved.

Description

technical field [0001] The invention relates to the field of augmented reality technology, in particular to a mobile terminal-based navigation method and system for anterior cruciate ligament reconstruction surgery. Background technique [0002] With the rapid development of technologies such as computer vision, image processing, and tracking and positioning, computer-aided surgical navigation has become one of the important research directions of surgical operations. It has been used in orthopedics, laparoscopy and other operations, and it has gradually been widely used in clinical practice because of its accuracy, high efficiency, and low radiation. Traditional total hip replacement surgery navigation completes the localization of the patient's lesion area based on the patient's preoperative three-dimensional image. Due to the complexity of the operation and the long operation time, the fatigue of the doctor will increase during the operation, which will affect the accura...

Problems solved by technology

The imaging methods of projectors and head-mounted displays require high costs and complex system settings, which are not conducive to widespread application, and enhancement lenses are not suitable for wide application in the front cross because they occupy too much work space and increase the difficulty of surgery Ligament reconstruction
