Staining localization can assist surgeons in accurately locating pulmonary nodules during surgery, achieving complete resection of the nodules while minimizing the resection area, thereby optimizing surgical outcomes.\n\nThe study will include individuals with pulmonary nodules detected by CT scans who require color localization assistance for thoracoscopic pulmonary nodule resection, randomly divided into two groups: one group will receive bronchoscopic navigation-assisted staining localization, while the other group will receive staining localization guided by an electromagnetic navigation system. The primary outcome is to evaluate the success rate of staining localization between the two groups.\n\nThis study aims to assess, through a prospective, single-center, randomized controlled clinical trial, whether the success rate of staining localization guided by bronchoscopic navigation robots (experimental group) is not lower than that of staining localization guided by the electromagnetic navigation system (control group), while potentially offering advantages such as a shorter learning curve, ease of operation, and reduced surgical time. This will provide a new efficient and safe method for the localization of pulmonary nodules clinically, greatly supporting accurate treatment of pulmonary nodules.",[83],"Lung Nodules","2025-02-09",{"date":86,"type":87},"2025-02-12","ACTUAL",{"date":89,"type":77},"2025-02-10",{"date":91,"type":77},"2026-03-31",{"name":5,"class":6},1]
