全自动检测系统在医用硬式内窥镜检测中的应用研究

Research on the Application of Automatic Detection System in Medical Rigid Endoscope Detection

目的评价使用全自动硬式内窥镜检测系统对硬式内窥镜光学性能检测的优势,并分析影响硬式内窥镜功能减退的潜在因素。方法选取某三级甲等综合医院2023年5—7月处理的硬式内窥镜镜头78条、导光束161条为研究对象,先后采用目测法和仪器检测法对其进行检测。仪器检测指标包括视向角、视场角、照度、景深、导光率、对焦、内窥镜内部密封性及纯净度;导光束指标包括光纤照度、导光率及色彩测试,比较2种检测方法的结果差异。结果目测法与仪器检测法检测硬式内窥镜镜头的合格率分别为94.87%和73.08%,差异有统计学意义(P<0.05);导光束的合格率分别为98.75%和96.89%,差异无统计学意义(P>0.05);仪器检测结果显示硬式内窥镜镜头的功能障碍主要集中在导光率和照度两方面。结论针对内窥镜镜头检测,仪器检测法明显优于目测法;针对导光束检测,两种检测方法未有显著差异。硬式内窥镜检测系统有助于及早发现硬式内窥镜镜头内部的结构变化和功能减退情况,是一种有助于降低内镜侵入诊疗操作风险、节约医院运营成本的科学检测工具。

Objective To evaluate the advantages of using automatic detection system to detect the optical performance of rigid endoscope and analyze the potential factors affecting the function decline of rigid endoscope.Methods A total of 78 rigid endoscope lenses and 161 guiding beams treated in a gradeⅢ-A hospital from May to July 2023 were selected as the research objects,and the visual method and instrument detection methods were used to detect them successively.Directional angle,field angle,illumination,depth of field,light transmittance,focusing,endoscope internal tightness and purity were included in the instrument detection indexes.Optical fiber illuminance,light transmittance and color measurement were included in the guiding beam index,and the results of the two detection methods were compared.Results The qualified rates of visual and instrument detection method were 94.87%and 73.08%,respectively,and the difference was statistically significant(P<0.05).The pass rates of guided beams were 98.75%and 96.89%,respectively,with no statistical significance(P>0.05).The instrument test results showed that the dysfunction of rigid endoscope lenses mainly focused on the light transmittance and illuminance.Conclusion For the endoscopic lens detection,the instrument detection method is obviously superior to the visual detection method,and for guided beam detection,there was no significant difference between the two detection methods.The rigid endoscope detection system is helpful for early detection of structural changes and functional decline inside the rigid endoscope lens,and is a scientific detection tool that helps to reduce the operational risk of endoscopic invasive diagnosis and treatment and save hospital operating capital.
