Abstract：It is well known that flexible endoscope is a very important medical equipment in the field of modern medicine. Therefore, we
should pay attention to how to properly use and maintain flexible endoscope in daily use and how to solve problems after failure. Starting
from the equipment structure, the routine maintenance and troubleshooting methods of flexible endoscopy were introduced, and the common
failures and solutions of flexible endoscopy in our hospital were listed in this paper. By analyzing the common faults of flexible endoscopy
in our hospital and summarizing the daily maintenance methods, this study provides technical support for the use of flexible endoscopy and
prolongs the service life of the equipment. This study can help clinical engineers get familiar with and master the routine maintenance work
of flexible endoscopy, and provide help for better use of flexible endoscopy
