手机水平仪联合激光引导装置在CT引导下经皮肺穿刺的应用OA

Objective To evaluate the application value of smartphone level meter combined with laser guidance device in CT-guided percutaneous lung puncture.Methods A historical control study was conducted,and enrolling 60 patients who underwent CT-guided lung puncture at the Fourth Affiliated Hospital of Anhui Medi-cal University from October 2023 to July 2025.A total of 60 patients(45 males,15 females)with a mean age of(72.90±8.82)years were included.30 patients who underwent CT-guided lung puncture,and 30 patients who re-ceived smartphone level meter-assisted procedures as the experimental group.The following parameters were com-pared between the two groups:coaxial needle insertion attempts,pneumothorax incidence,bleeding severity,puncture duration,and achievable puncture angle.Results The experimental group demonstrated significantly fewer coaxial needle insertion attempts[1.00(1.00,2.00)vs.2.00(2.00,3.00),P＜0.001],lower pneumotho-rax incidence(13.3％vs.36.6％,P=0.037),shorter puncture duration[(24.90±4.68)min vs.(29.93±10.11)min,P=0.02],and larger achievable puncture angles[19.50°(7.75°,41.00°)vs.7.00°(1.75°,25.25°),P=0.04]compared to the control group.No statistically significant difference was observed in bleeding severity(P=0.481).Conclusions The combination of a smartphone level meter and laser guidance device effectively reduces the number of coaxial needle insertion attempts,lowers the incidence of pneumothorax,shortens the procedure du-ration,and enables a wider achievable puncture angle in CT-guided percutaneous lung puncture.This technique shows promising clinical application value for improving the safety and efficiency of the procedure.
