What This Guide Helps With
Addresses poor aspiration or loss of vacuum caused by tubing, collection components, connections, occlusion, setup, settings, or external vacuum-path problems.
Step-by-Step Troubleshooting
1. Protect the Patient and Stop Dependence on Unreliable Aspiration
If aspiration becomes weak or unavailable during surgery, stop relying on the affected system and maintain suction using an approved alternate method or replacement CUSA setup.
Do not continue using an unreliable aspiration pathway if it could impair visualization or surgical control.
Expected outcome: The surgical team retains reliable suction while the affected system is removed from clinical dependence.
2. Confirm the Exact Aspiration Problem
Determine whether aspiration is absent, reduced, intermittent, noisy, or only weak under load. Ask whether the problem began suddenly or after a disposable change.
Perform a controlled nonclinical aspiration check.
Expected outcome: The reported symptom is reproduced and documented accurately.
3. Inspect the Collection Container and External Vacuum Path
Verify the collection container and associated connections are properly assembled, not full, not damaged, and correctly connected.
Inspect accessible tubing for disconnection, collapse, leakage, cracks, or improper routing.
Expected outcome: The collection and vacuum path are intact. If correcting a loose connection restores aspiration, proceed to final verification.
4. Trace the Aspiration Tubing to the Handpiece
Follow the entire tubing path and look for kinks, clamps, compression points, blockage, or tubing trapped beneath equipment.
Check connections at both ends for full engagement.
Expected outcome: The aspiration tubing is continuous, open, and correctly connected.
5. Inspect the Tip, Flue, and Handpiece Path for External Occlusion
Check accessible disposable components for visible material, incorrect assembly, or obstruction. Replace contaminated or suspect single-use components rather than attempting inappropriate cleaning or clearing techniques.
Do not insert tools into protected handpiece passages unless specifically authorized by manufacturer documentation.
Expected outcome: The disposable aspiration path is open and assembled correctly.
6. Verify Aspiration Controls and Settings
Confirm the selected aspiration setting and any related controls are appropriate for the test being performed.
Verify the footswitch or control input is commanding aspiration as expected.
Expected outcome: The system receives the intended aspiration command and settings are not limiting function.
7. Substitute Known-Good Tubing and Collection Components
If the external path appears intact but aspiration remains weak, install known-good compatible tubing or collection components as applicable.
Repeat the functional test.
Expected outcome: Aspiration returns with replacement consumables, identifying an external disposable problem, or the fault persists.
8. Compare Handpiece Setup
If appropriate, test with a known-good compatible handpiece setup to determine whether the problem follows the original handpiece or remains with the console.
Expected outcome: The failure is isolated to either the handpiece/disposable path or the console-side aspiration system.
9. Perform Final Functional Verification
Verify stable aspiration during a controlled nonclinical test and confirm the tubing remains open, collection system remains sealed, and controls respond consistently.
Verify irrigation and handpiece operation as appropriate before return to service.
Expected outcome: Aspiration is strong, stable, and repeatable. Troubleshooting can stop after all required testing passes.
10. Escalate Persistent Vacuum Failure
If the collection path, tubing, handpiece setup, disposables, connections, controls, and settings are correct but vacuum remains unavailable or weak, stop external troubleshooting.
Expected outcome: The system is removed from service for qualified evaluation of the aspiration subsystem.
If the Problem Persists
Common external causes have been ruled out. The remaining condition may involve the internal vacuum source, sensing, valves, aspiration control hardware, console electronics, or another service-level problem.
The device should be:
- Removed from service.
- Labeled Out of Service.
- Sent for repair or bench evaluation.
- Evaluated using appropriate Integra LifeSciences documentation and approved test equipment.
- Repaired or configured only by qualified personnel.
- Tested for reliable aspiration before return to service.
Knowing when to stop after verifying the complete external aspiration path is proper troubleshooting.
Clinical Use Tip
When aspiration fails during surgery, provide alternate suction immediately rather than allowing troubleshooting to delay surgical visualization or fluid management.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"OR staff reported weak aspiration from the CUSA Clarity handpiece during setup."
Cause
What was observed during troubleshooting.
Example:
"Clinical Engineering found the aspiration tubing partially collapsed where it was pinched beneath the console cart."
Resolution
What action was taken.
Example:
"Rerouted the tubing, verified stable aspiration and normal overall system function, and returned the unit to service."
Helpful Details to Include (If Known)
- Whether aspiration was weak, absent, or intermittent.
- Collection container status.
- Tubing condition and routing.
- Connection integrity.
- Visible occlusion or debris.
- Tip and flue installation.
- Aspiration control setting.
- Footswitch response.
- Results with known-good consumables or handpiece.
- Final aspiration and functional test results.
Final Thought
Reliable aspiration is essential to safe use. Follow the external vacuum path logically from collection components to the handpiece, correct simple restrictions first, verify operation, and escalate persistent console-level faults.
That is successful troubleshooting.
