Effect comparison of two methods for cleaning and disinfecting Da Vinci robotic surgical arm
Objective To explore the effective cleaning and disinfection method of Da Vinci robotic surgical arm.Methods A total of 200 pieces of Da Vinci robotic surgical arms used in the operating room of Jiangxi Provincial People's Hospital from January 2022 to April 2023 were retrospectively analyzed.Da Vinci robotic surgical arms were divided into observation group(100 pieces)and control group(100 pieces)according to different operation procedures.In the observation group,the operation end of the operating arm was cleaned by running water washing+laparoscopic enzyme soaking+ultrasonic clean-ing machine+steam cleaning machine+pure water rinsing with high pressure water gun+automatic cleaning machine.The cleaning and disinfection process of the control group was running water washing+laparoscopic enzyme soaking+ultrasonic cleaning machine+brushing the operating end of the operating arm+high pressure water gun rinsing+automatic cleaning machine cleaning and disinfection.Visual inspection method(quadruple magnifying glass with light source)and adenosine triphosphate(ATP)bioluminescence rapid detection method were used for detection.The backwash rate of unqualified cleaning quality was calculated,and the average time of cleaning and disinfection operation was compared between the two groups.Results The washback rate in the observation group was lower than that in the control group,ATP bioluminescence detection backwash rate of observation group was lower than that in the control group,and the differences were statistically significant(P＜0.05).The average cleaning and disinfection time in the observation group was shorter than that in the con-trol group,and the difference was statistically significant(P＜0.05).Conclusion The effect of cleaning and disinfecting Da Vinci robotic surgical arm by steam cleaning machine is more ideal than that by manual scruping,which saves a lot of cleaning and disinfecting time and effectively saves rare medical resources.
