Mizuho OSI Allegro
Mizuho OSI · Model Allegro
• 2 speed proportional, 4-way motorized table top movement with full patient load at any angle • Motorized table top movement ensures the user does not need to meet any physical requirements to travel the table top. There is no need to manually (float) push or pull the table top • 2 speed Joystick Controller – mounts on either side of table for ease of use • Flexibility in patient positioning- supine, prone and lateral • Edge to edge radiolucency • Excellent C-arm and O-arm® access • High stability, allowing patient head orientation at either end with 450 lb. ( 205 kg.) patient weight capacity • Electric floor locks • AC or battery operation • Hand Pendant can be connected to either the front or back of the pedestal of the table • Hand Pendant controls Height, Lateral Tilt(roll) and Trendelenburg/Reverse Trendelenburg and Table Top Travel at a single speed, Return to Level, Top Home • Tempur-Pedic® Medical table pad technology • Swivel Mount for Hand Pendant – allows pendant to be mounted horizontally [i]O-arm® is a registered trademark of Medtronic, Inc.[/i]
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.
