What This Guide Helps With

Troubleshooting smoke evacuation airflow, filter, tubing, suction setup, or blockage issues on the Stryker Neptune 3.

Step-by-Step Troubleshooting

Ensure Patient Safety First

Action: If the Neptune 3 is being used during a procedure and smoke evacuation is not working properly, notify OR staff immediately and provide alternate smoke evacuation or suction support.

Expected outcome: Surgical smoke is controlled using a safe alternate method before troubleshooting continues.

Why it matters: Smoke evacuation issues can expose staff and patients to surgical plume and may affect visibility at the surgical site.

Verify the Reported Problem

Action: Confirm the exact issue reported by staff. Ask whether the problem is:

Expected outcome: The complaint is confirmed and separated from general suction or fluid collection issues.

Why it matters: Smoke evacuation, suction, and fluid management problems can sound similar but may involve different accessories and flow paths.

Check That the Correct Smoke Evacuation Setup Is Being Used

Action: Confirm the Neptune 3 is set up with the proper smoke evacuation tubing, filter, wand, pencil adapter, or suction accessory required for the procedure.

Expected outcome: The system is connected with compatible smoke evacuation accessories.

If the wrong accessory or setup is found, correct the setup, test airflow, and stop if the issue is resolved.

Inspect the Smoke Evacuation Filter

Action: Check that the filter is installed correctly, fully seated, and not expired, saturated, damaged, or visibly contaminated.

Expected outcome: The filter is present, secure, and appropriate for use.

Why it matters: A missing, full, blocked, or poorly seated filter can reduce airflow or trigger a filter-related fault.

If replacing or reseating the filter clears the fault, document the filter issue and return the unit to service after functional verification.

Check for Tubing Kinks, Blockages, or Collapsed Lines

Action: Inspect the smoke evacuation tubing from the patient end back to the Neptune 3. Look for:

Expected outcome: Tubing is open, dry, properly routed, and connected to the correct smoke evacuation path.

If tubing replacement restores airflow, stop troubleshooting and document the accessory failure.

Check the Patient-End Accessory

Action: Inspect the smoke evacuation pencil, wand, nozzle, or laparoscopic tubing connection for obstruction or improper assembly.

Expected outcome: The patient-end accessory allows unrestricted airflow.

Why it matters: A clogged wand or pencil adapter can make the Neptune appear faulty even when the base unit is working normally.

Verify Smoke Evacuation Settings

Action: Confirm the smoke evacuation function is turned on and set to the expected level for the procedure. Check whether staff are using automatic activation, manual activation, or footswitch/remote activation if applicable.

Expected outcome: The smoke evacuation mode and flow setting match clinical use.

If the unit was set too low or not activated, adjust settings, verify airflow, and stop if resolved.

Check for Alarm or Indicator Behavior

Action: Observe the screen or indicators for filter warnings, airflow restriction messages, or smoke evacuation fault messages.

Expected outcome: The displayed message matches the reported issue.

Why it matters: A filter warning points toward filter seating, filter life, or obstruction. An airflow fault may point toward blocked tubing, filter restriction, or internal blower/sensor failure.

Power Cycle the Unit When Safe

Action: When the unit is not connected to active patient use, power it down, wait briefly, and power it back up.

Expected outcome: Temporary software or detection issues clear, and the smoke evacuation system initializes normally.

If the fault clears, perform a basic operational check before returning the device to service.

Test With Known-Good Accessories

Action: Replace the smoke evacuation filter, tubing, and patient-end accessory with known-good compatible items.

Expected outcome: Airflow improves and the fault clears if the issue was caused by an accessory or consumable.

Why it matters: Smoke evacuation faults are commonly caused by external disposables before the base unit is actually defective.

Check for Unusual Sounds, Heat, or Smell

Action: Listen for abnormal blower noise, grinding, rattling, or a fan that does not appear to run. Check for unusual heat or burning smell near the smoke evacuation section.

Expected outcome: The unit operates without abnormal noise, odor, or overheating.

If abnormal blower behavior, heat, or odor is present, remove the device from service.

Perform a Basic Functional Airflow Check

Action: With proper accessories installed, activate smoke evacuation and verify that airflow is present at the patient-end accessory.

Expected outcome: Airflow is strong and consistent, with no active filter or airflow fault.

If airflow is still weak or absent after filter, tubing, accessory, and setting checks, escalate for repair.

If the Problem Persists

If the smoke evacuation fault remains after checking setup, filter condition, tubing, accessories, settings, and basic power cycling, the likely cause is internal to the smoke evacuation system.

The device should be removed from service, labeled Out of Service, and sent for repair or bench evaluation.

Possible internal causes may include a blower failure, airflow sensor issue, filter detection problem, internal obstruction, control issue, or internal connection fault. Do not continue troubleshooting into internal repair during clinical support unless properly trained, equipped, and authorized.

Knowing when to stop is proper troubleshooting. Once external causes have been ruled out, continued use could create staff exposure risk or unreliable smoke evacuation performance.

Clinical Use Tip

Do not troubleshoot smoke evacuation problems while the unit is actively needed for a procedure unless patient and staff safety are already protected. Move the patient or procedure to a backup device, provide alternate smoke evacuation first, and maintain therapy continuity before evaluating the Neptune 3 when it is safe to remove it from service.

Work Order Documentation (CCR Method)

CCR = Complaint, Cause, Resolution

Complaint

What was reported by the clinical staff.

Example:
"OR staff reported the Stryker Neptune 3 had a smoke evacuation airflow fault and weak smoke capture during setup."

Cause

What was observed during troubleshooting.

Example:
"Found smoke evacuation filter not fully seated and smoke tubing partially kinked near the connection port."

Resolution

What action was taken.

Example:
"Reseated the smoke evacuation filter, replaced kinked tubing, verified airflow at the smoke evacuation accessory, and returned unit to service."

Helpful Details to Include (If Known)

Final Thought

Smoke evacuation faults should be handled with staff and patient safety in mind. Start with the external items most likely to fail: filter, tubing, accessories, setup, and settings. If those checks do not restore normal airflow, remove the Neptune 3 from service and escalate for repair. Clear CCR documentation helps show what was checked, what was found, and why the final decision was made.

That is successful troubleshooting.
