Abstract：Objective Because of the high maintenance cost of medical soft endoscope, a scientific maintenance strategy can be set up
to control hospital cost effectively. Methods Based on reliability centered maintenance (RCM) theory, the important functional units
of endoscope were listed. Then the FMEA analysis method was used to determine the failure mode, the cause of the failure and the
influence of the failure. Finally, the RCM logic decision diagram was used to get the corresponding maintenance of different faults
strategy and maintenance plan. Results After the implementation of the maintenance plan, the rate of Olympus endoscope overhaul in
our hospital decreased, and the maintenance mode was changed from post-maintenance to preventive maintenance. Conclusion The
application of RCM theory in medical equipment maintenance decision-making can provide reference for hospital management mode.
