Olympus Electronic Gastroscope GIF-Q180 Repair Case

Fault Detection

Insufficient and stiff angulation: Prolonged use has caused the angulation wires to stretch and degrade, with wear on the snake bone joints, resulting in stiff and jerky angulation adjustments.

Insertion tube with indentations: Frequent operation and external pressure have led to spiral tube deformation, visible indentations on the outer sheath, and reduced flexibility.

Nozzle clogging: Accumulated debris in the water and air channels has caused internal blockages, affecting air and water delivery functions.

Broken optical fibers and abnormal imaging: Severe breakage in the light guide fibers and delamination of optical glass have resulted in dim and unstable image transmission.

Small locking cap detachment: Loose fasteners in the control section caused the locking cap to fall off.

Button malfunction: Poor contact in Button 1 due to oxidized internal wiring in the button assembly.

Repair Plan

Replace snake bone and wires: Remove the worn snake bone and install a new, flexible OEM snake bone; replace with high-strength angulation wires and adjust tension to standard specifications.

Replace spiral tube and braiding: Remove the deformed spiral tube and install a new kink-resistant tube; reinforce the insertion tube with high-quality braiding for better pressure resistance.

Replace insertion tube and nozzle: Fully replace the indented insertion tube, clean and flush the water and air channels, and install a new nozzle.

Repair light guide assembly: Replace broken light guide fibers, re-bond delaminated optical glass, and test light transmission brightness.

Repair control section: Reinforce the locking cap fasteners; disassemble the button assembly, replace Button 1, and repair oxidized wiring.
