Objective:To explore the cleaning quality of different cleaning methods on robotically luminal apparatuses.Methods:This research innovated and invented specially cleaning holder that could support boiling after reducing pressure,and protective device for preprocessing so as to better clean robotically luminal apparatuses.A total of 600 robotic luminal apparatuses,which were used in urology surgery at The First Affiliated Hospital with Nanjing Medical University in November 2023,were selected as the research object,and they were divided into control group,experimental group 1 and experimental group 2 according to the principle of randomization and balance,with 200 apparatuses in each group.The luminal apparatuses of control group were cleaned as the cleaning process of the manufacturer's instructions,and these of experimental group 1 were cleaned through ultrasonic cleaning machine with perfusion in the cleaning process of the manufacturer's instructions,and boiling after reducing pressure was selected to clean those of experimental group 2 through specially cleaning holder that was innovated and invented,which could support boiling after reducing pressure.Both two experiment groups adopted protective device that was invented by our research patent.The visual estimation and magnifying glass(5-10 times)with light source,adenosine triphosphate(ATP)fluorescence detector,and detection device for protein residue were adopted to test and judge cleaning quality,cleaning time,and wear rate of transportation in luminal apparatus after cleaning.Results:The qualified rates of visual estimation and magnifying glass with light source in control group,experiment group 1 and experiment group 2 were respectively 94.5%,99.0%and 99.5%,and the differences of pairwise comparison among three groups were significant(x2=6.44,8.591,P<0.05).The qualified rates of the fluorescence detection and the detection for protein residue in control group were respectively 93.5%and 90%,and those in experiment group 1 were respectively 98.5%and 97%,and the differences among two groups were significant(x2=6.51,11.41,P<0.05).For the cleaning time of single apparatus,the experiment group 1 was shortest,and the experiment group 2 was longest,and there were significant differences in pairwise comparison among three groups(t=2.981,48.178,34.419,P<0.05).The cleaning time of 8 cleaned apparatuses of experiment group 1 still can keep advantage,while there was not significant difference in that between it and control group(P>0.05).The cleaning time of 12 cleaned apparatuses of experimental group 2 was shortest,and that of experiment group 1 was longest,and the differences of that among three groups were significant(t=2.743,5.292,3.177,P<0.05).The average wear rates of transportation of control group,experiment group 1 and experiment group 2 were respectively(9.5±1.8)%,(6.2±1.5)%and(5.8±1.3)%,and the average wear rates of transportation of experiment group 1 and 2 were significantly lower than that of control group,and the differences of that in pairwise comparison among three groups were significant(t=21.7,24.3,P<0.05),while the difference of that between two experiment groups was not significant(P>0.05).Conclusion:The cleaning technique of boiling after reducing pressure can play better cleaning effect for the slender lumen of robotic apparatuses,while the wear rates of experiment group 1 and 2,which use protective device for preprocessing,are better than that of control group.The full load amount of the application of the special cleaning holder of the robotic luminal apparatuses of experiment group 2 can increase by 1 time,which is high efficient and convenient.
