Invendo Medical invendoscope™ SC20
Invendo Medical · Model invendoscope™ SC20
Gentle Highly flexible materials are being used to ensure a small bending diameter of the endoscope. In addition the electrohydraulic deflection mechanism of the endoscope tip obviates the need to use Bowden cables, and thus maintains the flexibility. The combination of these technologies ensures that the forces exerted by the endoscope are reduced. Hygienic Resource-intensive and critical cleaning processes of the endoscope are avoided as the invendoscope is designed for single-use only Easy-to-use All endoscope functions including forward and backward driving, deflection of endoscope tip, rinsing, suction, insufflation and recording of images are controlled via a simple handheld device. This makes performance of colonoscopies ergonomical and supports ease-of-use. Interventional Versatility Due to its 3.1mm working channel the invendoscope SC20 can be also used for biopsies and routine therapeutic procedures such as polypectomy. The centralized working channel with the support of the deflectable electrohydraulic tip allows access to all locations in the colon.
Key tips
- ·A failed leak test means the scope does not get reprocessed or used - send it for repair, full stop.
- ·A shortened reprocessing cycle is a real infection-control failure, not a minor deviation - follow AAMI ST91 exactly.
- ·Track light-source lamp-hours against the manufacturer's limit rather than running to failure.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Fails the leak test
HighSymptoms: The manual or automated leak test fails; bubbles from the bending section, insertion tube, or a channel port.
Root cause: A pinhole in the bending-rubber, a channel breach, or a damaged distal cap - fluid invasion risk.
Poor or lost image
HighSymptoms: Blurred, dark, spotty, half-image or no image; colour cast that will not white-balance.
Root cause: Fluid invasion into the CCD / fibre bundle, a broken image bundle, or lens-surface damage / adhesive fog.
Angulation / bending-section fault
MediumSymptoms: Up/down or left/right angulation is loose, will not hold, over-tight, or limited range.
Root cause: Stretched or broken angulation wires, a worn brake, or bending-section damage.
Channel blockage / air-water or suction fault
MediumSymptoms: Poor suction, no or weak air / water, will not pass a cleaning brush.
Root cause: Debris or a kink in the channel, a worn air/water or suction valve seat, or a crushed channel.
Light-guide / connector fault
MediumSymptoms: Dim or no illumination from the scope with a known-good light source.
Root cause: Broken light-guide fibres or a damaged light-guide connector.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Leak testing before each reprocessing cycle
- ·Scope reprocessing per AAMI ST91
- ·Light source lamp-hour tracking
- ·Annual full PM
Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Fails the leak test
- Repeat the leak test, watching where bubbles originate (bending section, insertion tube, channels).
- Confirm the leak tester / connector itself holds pressure.
- Quarantine the scope immediately - do not reprocess a leaking scope in fluid.
- Send for channel / bending-section repair.
- Re-leak-test and re-image after repair before returning to service.
Symptom: Poor or lost image
- Confirm the processor, light source and monitor with a known-good scope.
- Inspect the distal lens for scratches, chips or adhesive fog.
- Check for fluid droplets behind the lens (invasion).
- White-balance and check all channels.
- Send for image-bundle / CCD repair if the fault is in the scope.
