Study on the effect of cleaning da Vinci patient side manipulator with steam cleaner

ObjectiveThis study compares the cleaning effect of patient side manipulators (PSMs) through manual cleaning and steam cleaning.MethodsA total of 2 400 contaminated da Vinci PSMs collected from September 2021 to September 2022 were randomly divided into experimental and control groups, each with 1 200 pieces. The control group adopted manual cleaning, and the steps were rinsing with running water, rinsing with a spray gun, bio-washing, ultrasonic cleaning, rinsing and repeating, drying, and sterilization. The experimental group added steam cleaning between the ultrasonic cleaning and the rinsing and repeating, and other steps remained unchanged. The qualification rates of the two groups were recorded and the damage rates of PSMs during the cleaning process were counted.ResultsThe results of visual inspection and adenosine triphosphate (ATP) bioluminescence assay showed that the qualification rate of the experimental group was higher than that of the control group (P<0.05), and the damage rate of PSM in the experimental group was lower than that in the control group (P<0.05).ConclusionCleaning PSM with steam cleaner significantly reduces the re-cleaning and damage rates and improves cleaning quality.

    Abstract：Driven by the large-scale expansion of healthcare services and innovations in surgical procedures, the clinical application scope of loaner instruments has expanded continuously. These instruments feature complex structures and frequent inter-institutional turnover, and their management involves multiple responsible parties, including manufacturers, distributors, central sterile supply departments (CSSDs), and surgical teams. Traditional manual management models are insufficient to meet the requirements of precision management. In the management of loaner instruments, the application of information traceability systems has gradually evolved from single-technology validation to integrated, multi-scenario implementation, accompanied by a steady increase in the volume of related research. This paper systematically reviews the application of information traceability systems in loaner instrument management in China. It highlights the advantages of these systems, including improved identification rates of loaner instruments, reduced instrument defect rates, enhanced reprocessing efficiency, greater medical staff satisfaction, and savings in medical resources. The review also summarizes the practical challenges and limiting factors currently encountered in their application, to provide a reference for medical institutions that wish to develop a more accurate, standardized, and fully traceable management system for loaner instruments.

    Abstract：ObjectiveThis study aimed to address the low efficiency of sterile item storage management in the Central Sterile Supply Department (CSSD) and to construct and validate the actual performance of a dual-robot collaborative scheduling system.MethodsA system integrating automated storage equipment and an intelligent scheduling algorithm was developed. A randomized controlled experiment was conducted to compare the time consumed to complete outbound and inbound tasks between a single-robot mode and a dual-robot mode.ResultsThe dual-robot collaborative strategy significantly improved operational efficiency. Under the single inbound port configuration, outbound efficiency increased by 21.8% and inbound efficiency by 10.1%. Under the dual inbound port configuration, inbound efficiency rose by as much as 43.5%. The inbound/outbound port was identified as a critical bottleneck affecting system performance.ConclusionDual-robot collaborative scheduling effectively enhances storage efficiency when combined with the optimization of key nodes, and has the potential for widespread adoption in similar hospital settings.
