摘　　要：目的 制作硬式内窥镜镜头清晰度检查辅助装置,并观察应用效果。方法 采取便利抽样法,选择某三甲医院2021年7-10月使用后的硬式内窥镜镜头800个作为研究对象,按照回收的时间顺序分为对照组和观察组,每组400个。观察组采用镜头清晰度检查辅助装置,对照组采用肉眼观察。比较2组检测耗时、人-物交叉污染发生率、镜头清晰度检测合格率。结果 单个镜头清晰度检查耗时<4 s检查镜头数,观察组占63.5%,明显高于对照组的49.3%(χ^(2)=16.540,P<0.05);与对照组人-物交叉污染发生率92.5%相比,观察组该指标降低至2%(χ^(2)=657.208,P<0.05),仅发生于防护面罩。镜头清晰度检测合格率观察组明显低于对照组(χ^(2)=13.330,P<0.05),分别为80.3%和89.5%。科室使用过程中观察组镜头无清晰度不合格情况。结论 硬式内窥镜镜头清晰度检查辅助装置,可有效缩短检查镜头清晰度的时间,降低人-物交叉污染发生率,提高清晰度不合格镜头的检出。Objective To fabricate an assistive device for checking the clarity of rigid endoscope lenses,and to observe the application effec.Methods A total of 800 rigid endoscope lenses used in a tertiary hospital from July 2021 to October 2021 were selected as the research objects by convenience sampling method,and they were divided into control group and observation group according to the chronological order of recovery,with 400 lenses in each group.The observation group was treated with lens clarity check aids,and the control group was observed with the naked eye.The detection time,the incidence of human-object cross-contamination,and the pass rate of lens clarity detection were compared between the two groups.Results The time required to check the clarity of a single lens was<4 s,and 63.5%of the lens was in the observation group,which was significantly higher than that in the control group(49.3%)(χ^(2)=16.540,P<0.05).Compared with the control group(92.5%),the incidence of human-object cross-contamination in the observation group decreased to 2%(χ^(2)=657.208,P<0.05),which only occurred in the protective mask.The pass rate of lens sharpness detection in the observation group was significantly lower than that in the control group(χ^(2)=13.330,P<0.05),which were 80.3%and 89.5%,respectively.During the use of the department,there was no unqualified clarity of the lens in the observation group.Conclusion The assistive device for checking the clarity of the lens of the rigid endoscope can effectively shorten the time of checking the clarity of the lens,reduce the incidence of human-object cross-contamination,and improve the detection of unqualified lenses.
