What This Guide Helps With
Identifies causes of visual distortions, artifacts, or image degradation that may interfere with accurate surgical visualization.
Step-by-Step Troubleshooting
Ensure Patient Safety First
Confirm the camera is not in use on an active patient. Move the procedure to a backup system before troubleshooting.
Inspect Camera Head and Connections
- Check that the camera head is fully seated in the coupler.
- Inspect the cable for kinks, pinches, or visible damage.
- Expected Outcome: Secure, undamaged connections often resolve minor image distortions.
Check Light Source and Intensity
- Verify the light cable is properly connected to the light source.
- Ensure the light intensity is set correctly and bulbs/LEDs are functioning.
- Why: Insufficient or uneven illumination can create artifacts.
Examine Monitor and Display Settings
- Confirm the display monitor is set to the correct input and resolution.
- Reset monitor brightness/contrast to default.
- Expected Outcome: Improper display settings can mimic image quality loss.
Perform a White Balance / Calibration Check
Follow on-screen prompts for white balance with a clean, neutral background.
Expected Outcome: Restores accurate color and reduces artifact appearance if miscalibration caused distortion.
Swap Cables or Camera Heads (if available)
Replace the camera head or cable with a known good unit.
Expected Outcome: Determines if the artifact is caused by a specific component.
Inspect for Lens Contamination or Damage
Check for smudges, condensation, or scratches on the lens. Clean with approved lens wipes.
Expected Outcome: Restoring a clean lens often resolves image blur or spots.
If the Problem Persists
Common external causes are ruled out; likely internal issue.
Remove the device from service.
Label as Out of Service and send for repair or bench evaluation.
Knowing when to stop protects patient safety and device integrity.
Clinical Use Tip
Never troubleshoot on an active patient.
Move procedures to a backup camera system first.
Handle optical components carefully to avoid scratches or contamination.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Surgeon reports blurry image with streaks and spots during procedures."
Cause
What was observed during troubleshooting.
Example:
"Cable and camera head inspected; lens had minor smudges. Light source and monitor settings confirmed normal."
Resolution
What action was taken.
Example:
"Lens cleaned, cable reseated, and calibration performed; image artifact resolved."
Helpful Details to Include
- Light source tested
- Camera head and cable swapped
- Monitor settings confirmed
- Lens inspection and cleaning
- Artifact type (streaks, blur, noise)
- Device status after troubleshooting
Final Thought
Effective troubleshooting prioritizes patient safety, systematically rules out external causes, and documents all findings. Escalate promptly if internal issues remain unresolved to ensure uninterrupted surgical imaging.
That is successful troubleshooting.
