Mizuho OSI Trios
Mizuho OSI · Model Trios
650 lbs. Weight Capacity Powered Floor Locks New table top connection interface Carbon fiber frame provides complete radiolucency Unrestricted C-arm and O-arm® access Open frame reduces vena cava compression, minimizes epidural venous bleeding and improves visualization at the surgical site Customizable pad and component placement to meet individual patient needs Adjustment of table top’s position relative to the cross bar is readily achieved using tower’s unique ratchet mechanism The IntelliPENDANT®, a software-driven hand pendant, controls all table functions: Floor Locks, Height, Lateral Roll, Trendelenburg/reverse Trendelenburg and Return to Level Auxiliary Panel provides a secondary source for controlling table motion Tempur-Pedic® Medical Pad technology incorporated into all patient surfaces Facilitates safe and efficient rotations from supine to prone through 180 degree rotation
Key tips
- ·Never defeat or bypass a return-electrode monitoring (REM) alarm to finish a case - it's a direct burn risk.
- ·Verify OR table battery backup - a table that loses power mid-procedure is a real, documented incident type.
- ·Track surgical light lamp-hours rather than waiting for failure - a sudden failure mid-case is avoidable.
Typical Failure Modes
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
Height / tilt actuator fault
HighSymptoms: Table won't move to commanded position, or moves erratically.
Root cause: Hydraulic pump or electric actuator wear/failure.
Control pendant / remote fault
MediumSymptoms: Unresponsive or intermittent hand/foot control.
Root cause: Pendant cable, contacts, or wireless receiver wear.
Section articulation / lock fault
MediumSymptoms: Back, leg, or Trendelenburg section won't lock or articulate.
Root cause: Articulation mechanism or locking pin wear.
Caster / base wear
LowSymptoms: Wobble, drift, or difficulty repositioning the table.
Root cause: Caster or locking-wheel mechanism wear.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Pre-case functional check
- ·Electrosurgical return-electrode cable inspection
- ·Table hydraulic / mechanical inspection
- ·Annual electrical safety test and full PM
Troubleshooting Approach
A structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Height / tilt actuator fault
- Confirm the presentation - typically table won't move to commanded position, or moves erratically.
- Check the most likely cause first: hydraulic pump or electric actuator wear/failure.
- Inspect the affected subsystem against the manufacturer's inspection checklist.
- If the fault is confirmed and not a field adjustment, service or replace the hydraulic pump / electric actuator per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
Symptom: Control pendant / remote fault
- Confirm the presentation - typically unresponsive or intermittent hand/foot control.
- Check the most likely cause first: pendant cable, contacts, or wireless receiver wear.
- Inspect the affected subsystem against the manufacturer's inspection checklist.
- If the fault is confirmed and not a field adjustment, service or replace the control pendant / remote assembly per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
