Problems solved by technology
Since pulmonary nodules or tumor lesions are adjacent to the main trachea, artery and heart area, and the imaging of the patient's lesion in the early stage will change with the patient's body position, there are errors in the accuracy of the surgical path, which requires high surgical accuracy. Therefore, the surgical risk High, easy to cause large wounds and poor treatment effect

The invention provides an AR display method for lung argon-helium knife surgical path data. The method includes: generating an initial three-dimensional model of the patient's chest according to the chest DICOM medical digital imaging and communication files of the patient's chest. Mark the location to be treated. In the initial 3D model, the location to be treated is identified as the scattering origin, the puncture length of a surgical tool is used as the scattering radius, and the diameter of the surgical tool is used as the ray width to obtain multiple scattering paths for various surgical tools reaching the external surface. Get one or more junction-free paths. Thereby, the puncture path data of one or more surgical tools are obtained. In the present invention, based on the alignment image, the three-dimensional model of the patient and the simulated surgical path are superimposed on the current human body imaging, so as to obtain the surgical path with high safety and suitable for the implementation of the actual surgical tool. Reduce the wound area and ensure the safety of the operation. The invention also provides a generation system for the operation path data of the lung argon-helium knife.
Description
technical field [0001] The invention relates to the field of auxiliary medical treatment. Used in minimally invasive surgery. The invention specifically relates to an AR / MR display method and system for lung argon-helium knife surgery path data. Background technique [0002] In the minimally invasive treatment of pulmonary nodules or tumors, doctors perform surgery based on the location of the lesion determined by the patient before surgery. The surgical path was determined by diagnosing the location of the lesion before the operation. During the operation, the lesion location will be treated according to the surgical path in conjunction with the endoscopic imaging method. Since pulmonary nodules or tumor lesions are adjacent to the main trachea, artery and heart area, and the imaging of the patient's lesion in the early stage will change with the patient's body position, there are errors in the accuracy of the surgical path, and high surgical accuracy is required. Theref...
