To compare the clinical effect of disposable pulmonary nodule positioning needle and micro-coil in the pre-thoracoscopic positioning of solitary pulmonary nodules.

From May 2020 to December 2020, 60 patients who underwent thoracoscopic pulmonary nodule resection admitted to Xuzhou Central Hospital were selected as the control group, Micro-coil positioning before surgery, From January 2021 to August 2021, 60 patients who underwent thoracoscopic pulmonary nodule resection in our hospital were included in the observation group, Preoperatively use a disposable pulmonary nodule locating needle to locate. The positioning-related results and surgical data of the two groups of patients were compared.

The positioning success rate of the observation group was 100% (60/60), and the positioning success rate of the control group was 98.3% (59/60), the difference was not statistically significant (P > 0.05).The positioning time of the observation group (9.4 ± 3.8) min was shorter than that of the control group(16.5 ± 6.3) min, and the difference was statistically significant (P < 0.05). The incidence of complications in the observation group (10.0%~11.7%) and the control group (10.0%~13.3%) were not statistically different (P > 0.05). The success rate of thoracoscopic surgery in both groups was 100% (60/60), the operation time of the observation group (87.3 ± 60.7) was less than that of the control group (92.9 ± 36.7), and the difference was not statistically significant (P > 0.05).

Before solitary pulmonary nodule thoracoscopic resection, CT-guided disposable pulmonary nodule positioning needle and micro-coil positioning are safe, reliable and effective, suitable for clinical application. Compared with the micro-coil positioning operation, the disposable lung nodule positioning needle is simpler and time-saving.
