Abstract:Objective To explore the failure cause of rigid endoscope and take feasible measures with five whys method. Methods
Firstly, failure cause investigation team was formed to find out the three direct failure causes which were collision of cleaning and
disinfection process, aging wear and improper operation via the data collecting and sorting. Then, the cause-and-effect relation chain
was applied to work out the root cause with the five whys method. Consequently, it came up with the targeted measures and carried
out it. Results Applying the five whys method to the quality management of rigid endoscope, the annual maintenance times and
maintenance fees decreased by 66.7% and 59%, respectively. Conclusion It can find out the root cause of rigid endoscope failure and
make long-term effective measures to avoid the similar failure occurring again with five whys method.
