Medical Endoscope Troubleshooting

In terms of organization and management: such as the division of professional groups, one specialist and multiple abilities; calculation of complex coefficients of instruments, reasonable sharing; division of departments or instruments to people, and responsibility for the responsibility; organization of fault consultation; chief engineer responsibility system, etc.
In terms of personnel training: such as the combination of introduction and training, the gradual formation of a talent echelon, the combination of on-the-job improvement and outbound training, the combination of in-depth basic theory and professional technology improvement, etc.
In terms of maintenance procedures: first understand the cause of the instrument failure, be familiar with the working principle of the instrument, then use the basic theoretical knowledge you have mastered to analyze the possible location of the failure on the circuit diagram of the instrument, and gradually detect and troubleshoot to find out the real location of the failure, and finally repair it Or replace faulty parts, and complete partial or complete machine debugging.
Maintenance method: Inquiry first, then diagnosis; first visual inspection, then inspection; first comprehensive, then partial: first drive, then circuit; first independent, then complete machine; first peripheral, then chip; first control, then data; first Qualitative, post-quantitative, etc. dialectical relationship principles.
Generally, there are more mechanical parts than circuit parts in faulty parts; more strong current parts than weak current parts; more high-temperature parts than low-temperature parts; more power parts than main parts; more transmission parts than static parts; There are more components than semiconductor devices, and more analog circuits than digital circuits. The detection methods include tapping method, intuitive method, measurement method, comparison method, replacement method, variable temperature method, signal tracking method, signal input method, front and back tracking method , load separation method and other practical methods.
