Application of 3D Navigation and Vascular Reconstruction Technology in Precision Resection of Lung Segment

With the rapid development of imaging technology and the improvement of people's health awareness, more early lung cancers are found. For very early lung cancer (mainly manifested as ground glass nodules), lobectomy is still the standard surgical treatment for lung cancer, and segmental resection has been used clinically as a treatment method. 3D navigation is an effective tool for precise lung segment and sub-segment resection. Three-dimensional vascular reconstruction technology is an advanced imaging technology. Accurate segment resection under thoracoscopy is considered the best surgical treatment for early stage lung cancer. It is difficult to accurately estimate the morphology, nature and other characteristics of the tumor and its surroundings by two-dimensional imaging alone. Therefore, the precise resection operation adds great difficulty and risk to the surgeon. In recent years, 3D navigation and vascular reconstruction techniques have been widely developed and applied in the medical field, and they are rarely used in thoracic surgery. This article has conducted a more in-depth study on the application of 3D navigation technology and vascular reconstruction technology in precision lung resection, and has achieved certain research results
