Abstract:
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.
