Common fault analysis and preventive measures of electronic endoscope operation department

1. Leakage of control buttons and angle knobs may cause water to enter the operation part and cause electrical short circuit. The common cause of failure is that the control button collides with sharp parts, or the button rubber is aging due to long-term use. The main preventive measures are to handle with care and do a leak test before use.
2. The suction port is worn out. In severe cases, automatic suction will occur. Although the suction volume is small, it will directly cause insufficient air supply, unable to fully fill the stomach, and maintain a long-term air supply state. The wrong method of pulling out the accessories will often lead to the wear of the suction port, and strengthening the user's standard operation can avoid this failure.
3. Angle steel wire is broken, mainly caused by excessive force when making an angle and exceeding the angle range. Standard operation and use can avoid this failure. When making an angle, the movement should be gentle, so as not to hurt the patient, and secondly, to protect the angle steel wire.
