[Clinical value of holographic multimodal real-time three-dimensional navigation technology in the surgical location of pulmonary lesions].

To investigate the clinical value of holographic multimodal real-time three-dimensional navigation (3D-HMRN) technology for navigation and localization of pulmonary micro lesions. A total of 152 patients who underwent thoracoscopic partial resection of small pulmonary nodules in the Department of Thoracic Surgery of the First Medical Center of Chinese PLA General Hospital from June 2017 to December 2019 were retrospectively collected and were divided into two groups by computer random number. The experimental group consists of 76 patients (31 males and 45 females) with a mean age of (47±17) years. CT scan in lateral position navigation mode and 3D reconstruction of the surgical area were performed on all patients. Before the operation, holographic multimodal real-time 3D navigation technology was used to guide the puncture of the lesion. After the operation was completed, the intraoperative CT was used to verify the location of the puncture and determine the accuracy and error rang of the puncture. The control group consists of 76 patients (34 males and 42 females) with a mean age of (50±19) years. Intraoperative CT positioning was directly subjected to the patients. And then, the localization data of the two groups were compared and statistically analyzed. Seventy-six cases of positioning puncture using navigation technology, the first success rate was 97.4%, the error was (3.9±0.9) mm, and the average operation time was (4.4±1.2) min; while the success rate of one-time CT positioning during routine surgery was 98.7%, the error was (3.5±1.0) mm, and the average operating time was (10.7±2.6) min. Compared with intraoperative CT positioning, the success rate and positioning accuracy of 3D-HMRN were not statistically significant (both 0.05), however the operation time was significantly shortened (0.01). The holographic multi-modal real-time 3D navigation technology saves time and has accurate positioning, which may be used as an effective method for localization of pulmonary micro nodules during surgical treatment.
