What This Guide Helps With
This guide assists Clinical Engineering in troubleshooting a Skytron 6500 Series surgical table that exhibits hydraulic issues, such as slow positioning, uneven movements, or visible fluid leaks. These issues may impact table safety and surgical workflow. Focus is on external and easily verifiable checks before assuming internal hydraulic failure.
Common symptoms include:
- Table moves slowly or unevenly during height, tilt, or lateral adjustments
- Unusual noises (hissing or groaning) during movement
- Visible hydraulic fluid around the base, column, or lift mechanisms
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Verify no patient is on the table.
- Move any patient to another table if necessary.
- Confirm table is not under load while troubleshooting.
Check Power and Setup
- Confirm table is properly plugged in and power switch is ON.
- Observe indicator lights to ensure system is active.
- Power cycling may reset some electronic flow controls.
Inspect Hand Control and Pendant
- Verify hand control or foot pendant functions normally.
- Unresponsive controls can mimic hydraulic slowness.
- Swap hand control with a known working unit if available.
Check Hydraulic Fluid Level (External Reservoir if Accessible)
- Look for fluid sight glass or level indicators.
- Low fluid can cause slow or uneven movements.
- Top off only if safe and manufacturer-approved fluid is available.
Visual Inspection of Hydraulic Lines and Connections
- Inspect hoses, fittings, and visible cylinders for leaks or damage.
- Look for wet spots, drips, or fluid stains.
- Tighten loose fittings carefully without forcing connections.
Observe Table Movement Under No Load
- Test each movement (height, tilt, lateral) individually.
- Note any slow response or irregular motion.
- Listen for abnormal hissing, groaning, or jerky action.
Check for Obstructions
- Ensure base and lift mechanisms are free of debris.
- Verify cables or other items are not pinched, restricting cylinder travel.
If the Problem Persists
If table continues to move slowly, drift, or shows persistent hydraulic leaks after external checks:
- Remove table from service
- Label table Out of Service
- Send to authorized repair or bench evaluation
Clinical Engineering should avoid internal cylinder or pump disassembly; this requires manufacturer service.
Knowing when to escalate prevents unsafe operation and further damage.
Clinical Use Tip
- Never troubleshoot hydraulic or electronic functions with a patient on the table.
- Always verify safe patient transfer before testing table movements.
- Avoid quick or forced adjustments that may worsen leaks or stress components.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
“Table moves slowly during height and tilt adjustments; visible hydraulic fluid under base.”
Cause
What was observed during troubleshooting.
Example:
External inspection revealed minor leaks at a cylinder fitting and low fluid in reservoir.
Resolution
What action was taken.
Example:
Table removed from service, labeled Out of Service, and sent for authorized repair.
Helpful Details to Include
- Outlet tested and confirmed live
- Cables and pendant tested
- Movements observed under no load
- Location of leak and fluid color/type
- Final device status: Out of Service
Final Thought
Hydraulic performance is critical for safe surgical table operation. External checks allow Clinical Engineering to rule out simple issues, but persistent slowness or leaks always warrant professional repair. Proper documentation ensures clear communication and maintains patient safety.
That is successful troubleshooting.
