Accurate puncture of targets in the lower lung lobes with respiratory motion using a teleoperated robotic system and low-dose computed tomography fluoroscopy: an experimental animal study

Year: 2024

Type: article

Abstract: Background: Traditional freehand puncture relies on non-real-time computed tomography (CT) images, which significantly affects the accuracy of puncturing targets in the lower lung lobes with respiratory motion. This study aims to assess the safety and feasibility of a teleoperated robotic system and low-dose CT for the accurate real-time puncture of targets in the lungs of live pigs during breathing under fluoroscopic guidance. Methods: test. Results: The puncture accuracy rate was 100% in both groups. The RD was similar between the groups (P=0.25414). Nonetheless, the surgical robotic system was associated with a significantly shorter OT and PT and a smaller NA (P=0.00016, 0.00015, 0.00005). Conclusions: Teleoperated robotic systems combined with low-dose CT can accurately puncture millimeter-level targets in the lower lung lobes in real time during breathing under fluoroscopic guidance. Compared with freehand puncture with intermittent scans, the new technique reduces the NA and shortens the OT and PT. Moreover, this technique can improve the targeting and interventional treatment of tumors.
