Long-term use has caused severe deformation at the end of the insertion tube. Residual tissue protein on the surface is dehydrated and adhered during disinfection by glutaraldehyde, and long-term accumulation with the outer skin forms crystals, leading to holes and wear on the outer skin of the insertion tube.
4.Fault Handling:
Overhaul, replace the insertion tube; replace the outer skin.
5. Post-Repair Effect:
6. Endoscope Maintenance Tips：
Maintenance of the endoscope host
