What This Guide Helps With

Troubleshooting traction spar, leg support, boot, or locking difficulty caused by positioning, debris, accessories, or mechanical resistance.

Step-by-Step Troubleshooting

Ensure Patient Safety First

Do not troubleshoot traction spars, leg supports, boots, or locking mechanisms while the patient is supported by the affected component.

If the issue occurs during a case, notify clinical staff and follow facility procedure for safely supporting or transferring the patient before further troubleshooting.

Expected outcome: The patient is not placed at risk by an unstable traction or leg support component.

Why it matters: Traction assemblies and leg supports directly affect limb positioning, patient stability, and surgical access.

Confirm the Reported Problem

Ask staff which component is difficult to adjust or lock:

Attempt the adjustment only when the table is unloaded and safe to manipulate.

Expected outcome: The affected component and symptom are clearly identified.

If the component adjusts and locks normally unloaded, stop and document that the issue could not be duplicated under safe test conditions.

Inspect for Obvious Obstruction or Misalignment

Visually inspect the traction spar, leg support, and mounting interface for drapes, straps, pads, cables, debris, or other accessories interfering with movement.

Remove any obstruction and retry the adjustment.

Expected outcome: The component moves freely and locks securely once interference is removed.

If this resolves the issue, return the table to service after functional verification.

Check Accessory Installation and Seating

Verify that the traction spar, boot assembly, or leg support is fully seated in its mounting receiver or rail clamp.

Remove and reinstall the accessory if safe to do so.

Expected outcome: The accessory seats fully, aligns correctly, and locks without excessive force.

Why it matters: Partially seated accessories may feel jammed, may not lock fully, or may bind during adjustment.

Inspect Locking Knobs, Levers, and Release Mechanisms

Check that the locking knob or lever is not already over-tightened, cross-loaded, or held under tension.

Fully release the locking mechanism, reposition the component, then re-lock it using normal hand force only.

Expected outcome: The mechanism releases, adjusts, and locks without forcing.

If the lock holds correctly after proper release and reset, stop and document the correction.

Check for Load or Position-Related Binding

Confirm the traction spar or leg support is not being adjusted while under weight, side load, or traction force.

Place the component in a neutral unloaded position and try the adjustment again.

Expected outcome: The component moves more freely when unloaded and properly aligned.

Why it matters: Traction assemblies can bind when adjusted under tension or when the limb support is not aligned with the mechanism.

Inspect for Fluid, Cleaning Residue, or Debris Buildup

Look for dried prep solution, cleaner residue, surgical debris, tape adhesive, or corrosion around sliding surfaces, clamps, and locking points.

Clean accessible external surfaces according to facility-approved cleaning practices.

Expected outcome: External residue is removed and the component can be adjusted normally.

Do not lubricate unless approved by the manufacturer or facility procedure. Unapproved lubricant can attract debris or affect locking reliability.

Compare With a Known-Good Matching Accessory

If another compatible Hana traction spar, boot assembly, or leg support is available, compare fit and operation on the same table.

Also test the suspect accessory on another compatible table only if safe and approved by local process.

Expected outcome: The issue follows either the accessory or the table mounting location.

Why it matters: This helps separate a table-side receiver problem from a damaged accessory.

Inspect for Visible Damage or Wear

Check for bent spars, cracked handles, stripped knobs, loose hardware, worn clamps, damaged boot attachment points, or deformed mounting surfaces.

Do not attempt to straighten, force, or modify the component.

Expected outcome: No visible damage is present, or damaged parts are identified for repair.

If damage is found, remove the affected component from service.

Verify Locking Security After Adjustment

Once adjusted, apply a controlled, reasonable manual check to confirm the traction spar or leg support remains secure.

Do not use excessive force or simulate patient loading beyond normal safe handling.

Expected outcome: The component remains locked and does not slip, rotate, or loosen.

If the component slips or will not hold position, remove it from service.

Check Table Configuration and Compatible Accessories

Confirm the accessory belongs with the Hana Orthopedic Surgery Table and is not from another table system or incompatible setup.

Verify staff are not mixing boots, spars, clamps, adapters, or support components from different systems.

Expected outcome: The table and accessory combination is correct.

If an incompatible accessory is identified, remove it and provide the correct compatible component.

Perform Final Operational Check

With the table unloaded, verify the affected traction or leg support assembly can:

Expected outcome: The component operates smoothly and locks reliably.

If the final check passes, return the table or accessory to service and document findings.

If the Problem Persists

If the traction spars, leg supports, boots, or locking mechanisms remain difficult to adjust or will not lock after external checks, common user-accessible causes have been ruled out.

The issue may involve worn locking hardware, damaged mechanical interfaces, bent support components, internal clamp wear, or table/accessory mechanical failure.

The affected table or accessory should be:

Knowing when to stop is proper troubleshooting. Do not force traction components or continue using supports that cannot be verified as secure.

Clinical Use Tip

Do not troubleshoot traction spars or leg supports while they are supporting a patient’s limb. If the component is unstable, difficult to lock, or slipping during setup, stop and move to a safe alternate setup before proceeding. Maintain therapy continuity and patient positioning safety by moving the patient to a backup device or alternate support setup before troubleshooting continues.

Work Order Documentation (CCR Method)

CCR = Complaint, Cause, Resolution

Complaint

What was reported by the clinical staff.

Example:
"OR staff reported that the Hana Orthopedic Surgery Table left traction spar was difficult to adjust and would not consistently lock during setup."

Cause

What was observed during troubleshooting.

Example:
"Inspection found dried residue and minor debris around the traction spar locking interface, preventing smooth adjustment."

Resolution

What action was taken.

Example:
"Cleaned accessible locking surfaces, reinstalled the traction spar, verified full adjustment range and secure locking, and returned the table to service."

Helpful Details to Include (If Known)

Final Thought

Traction and leg support issues on the Hana Orthopedic Surgery Table should be handled carefully because these components affect patient positioning and stability. Start with safe external checks, verify accessory seating and locking, avoid forcing mechanical parts, and escalate when locking security cannot be confirmed. Clear CCR documentation helps show what was tested, what was found, and why the final service decision was appropriate.

That is successful troubleshooting.
