Research on “Augmented Reality” Assisted Precise Thoracoscopic Resection of Pulmonary Nodules

To break with traditional preoperative localization, a porcine animal model to evaluate the safety of augmented reality (AR) assisted localization of solitary pulmonary nodules (SPN) was used. Before the experiment, Microsoft HoloLens AR system was used to bring the CT image into the laboratory after 3D reconstruction. The virtual model was fitted with real body surface markers, and the virtual positioning auxiliary line and auxiliary locator were used to perform puncture positioning before surgery. Data related to actual puncture path and expected planned path were recorded in the experiment. SPSS 26.0 was used to calculate the puncture accuracy under AR assisted positioning, and the results obtained were acceptable in segmentectomy or wedge pneumonectomy. Its feasibility in animal models will also be evaluated, and its safety and efficacy will need to be further studied in clinical trials.
