1) Water and gas pipe deformation, resulting in poor water and gas delivery.

 

2) Suction pipe deformation, resulting in poor suction; during suction, foreign objects are ejected from the forceps inlet/suction switch.

 

3) Insertion of instruments into the biopsy channel is not smooth, with obvious obstruction (all refer to the insertion tube section afterwards).

 

4) Insufficient wire angle, tight angle.

5) Poor lighting effect, insufficient brightness.

 

6) Black spots and image loss in the fiber optic image.

 

Deformed insertion tubes are easily contaminated with pollutants, causing cross-infection or larger malfunctions after breakage.

 

When obvious bite marks exist on the curved rubber part, it is usually accompanied by:

 

1) Water leakage from the curved rubber.

 

2) Deformation of the snakebone, incorrect angle.

 

3) Deformation of the spiral tube, incorrect angle.

 

4) Wire detachment/elongation/compression, incorrect angle.

 

Deformed insertion tubes are easily contaminated with pollutants, causing cross-infection or larger malfunctions after breakage.
