To explore the safety and feasibility of wireless thoracoscope in thoracic surgery. A retrospective analysis was made of all the clinical data of 90 patients with thoracoscope lung resection, from April to August 2021, Shanghai changzheng hospital thoracic minimally invasive center. Compared the thoracoscope preparation time, picture resolution, picture delay, surgeon comfort level, assistant comfort level between the wireless thoracoscope group and wired thoracoscope group. The thoracoscopic preparation time of the wireless thoracoscope group was significantly shorter than that of the wired group (26.66 ± 6.04 vs 62.14 ± 10.07, p < 0.0001). Comfort level of the surgeon (4.64 ± 0.48 vs 3.77 ± 0.42, p < 0.001) and the comfort level of the assistant (4.85 ± 0.36 vs 3.88 ± 0.32, p < 0.001) of the wireless thoracoscope group were higher than that of the wired thoracoscope group. There were no statistically significant differences in video sharpness (4.64 ± 0.48 vs 4.74 ± 0.44, p = 0.31). Although there was one case picture delay in wireless group, it was caused by low power which could be dealt with by a good charge before surgery. The wireless thoracoscope has the advantages of short preparation time, high comfort for the surgeon and the assistant, no less than the wired thoracoscope in picture resolution and picture delay. Wireless connection is more convenient and portability, which is worthy of further application in clinical practice. [ABSTRACT FROM AUTHOR]
