目的:应用硬式内窥镜检测仪检测法和目测检测法检测评估硬式内窥镜的导光性能和成像性能,探讨硬式内窥镜检测仪检测硬式内窥镜光学性能的应用效果。方法:选取2022年5月至2023年5月北京协和医学院肿瘤医院膀胱镜手术使用的174件硬式内窥镜,分别采用目测法和检测仪法对174件硬式内窥镜进行清洗消毒后的检测。根据检测方式不同,将其分为目测组(90件)和检测仪组(84件)。对比分析两种检测硬式内窥镜导光性能和成像性能的方法,比较两种检测方法的检测效果。结果:检测仪组和目测组光通量不合格检出率分别为11.9%(10/84)和0(0/90),两组硬式内窥镜导光性能的光通量检测比较,差异有统计学意义(x^(2)=9.276,P<0.05)。硬式内窥镜成像性能检测中检测仪组和目测组的成像质量不合格检出率分别为9.5%(8/84)和1.11%(1/90),两组比较差异有统计学意义(x^(2)=6.269,P<0.05)。结论:应用硬式内窥镜检测仪可提高消毒供应中心工作人员检测硬式内窥镜光学性能的准确率,完善硬式内窥镜的质控管理,降低硬式内窥镜损耗率,延长硬式内窥镜的使用寿命,为临床提供更加安全有效的医疗器械,保障医疗安全。

Objective:To test the performances of conducting light and imaging of rigid endoscopes by applying detection method with detector and visual detection method,and to explore the application effect of rigid endoscope detector in testing the optical performance of rigid endoscope.Methods:A total of 174 rigid endoscopes that were used in surgery with bladder endoscopy at Cancer Hospital of Beijing Union Medical College from May 2022 to May 2023 were selected.The visual detection method and detection method with detector were adopted respectively to perform detection after cleaning and disinfection for 174 rigid endoscopes.According to different detection methods,the 174 rigid endoscopes were divided into visual detection group(90 pieces)and detector group(84 pieces).The performances of conducting light and imaging of the two kinds of detection methods were compared and analyzed,and the results of the two kinds of detection methods were compared.Results:In the testing of the light guiding performance of rigid endoscopes,the detection rates of unqualified items in the detector group and the visual group are 11.9%(10/84),0(0/90),respectively,the difference in luminous flux between the two groups was statistically significant(x2=9.276,P<0.05);in the imaging quality testing of rigid endoscope imaging performance,the detection rates of unqualified images in the detector group and the visual group are 9.5%(8/84),1.11%(1/90),respectively.The difference between the two groups is statistically significant(x2=6.269,P<0.05).Conclusion:The application of rigid endoscope detector can increase the accuracy of CSSD staff in detecting the optical performance of rigid endoscope,and improve the management of quality control of rigid endoscope,and reduce the loss rate of rigid endoscopes,and extend the service life of rigid endoscopes,and provide safer and more effectively medical devices for clinical work,and ensure medical safety.
