Stryker Visum LED
Stryker · Model Visum LED
Stryker's Visum LED surgical light.
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
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Lamp / LED failure or reduced illuminance
MediumSymptoms: One or more heads / LED segments out, dim head, uneven or discoloured light field.
Root cause: Halogen lamp at end of life or a failed LED module / driver, a lamp-changeover fault, or a power-supply fault.
Spring-arm / suspension drift
HighSymptoms: Light head drifts up or down, will not stay positioned.
Root cause: Spring-arm counterbalance out of adjustment or worn friction brakes.
Intensity / focus control fault
MediumSymptoms: Brightness or spot size will not adjust from the wall panel or sterile handle.
Root cause: Control PCB, the wall-plate keypad, or the handle switch.
Sterilizable handle fault
LowSymptoms: Handle loose or not detected.
Root cause: Worn handle mount / contacts.
Power-supply fault
MediumSymptoms: Whole head dark, flicker, or will not power on.
Root cause: Failed lamp / LED power supply.

Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Lamp / LED out, dim, or uneven / discoloured field
- Confirm mains power to the light and the wall-plate / control panel.
- Replace the failed lamp or LED module (let a halogen head cool first) and check the lamp-changeover mechanism.
- Replace the lamp / LED power supply if the head is unpowered.
- Check the fibre-optic cable for dark (broken) fibres against a bright light (headlights / fibre heads).
- Verify even, full illuminance across the field after the repair.
Symptom: Light head drifts / will not hold position
- Adjust the spring-arm counterbalance for the fitted head weight per the manual.
- Check and adjust the friction brakes at each joint.
- Replace the counterbalance / friction-brake kit if adjustment does not hold.
- Cycle the arm through its full range.
- Confirm the head stays put at several working positions.
Symptom: Intensity / focus / spot size will not adjust
- Test from both the wall panel and the sterilisable handle.
- Check the control PCB and the wall-plate keypad ribbon / cable.
- Inspect the sterilisable-handle switch and its contacts.
- Replace the handle or the keypad as isolated.
- Confirm the full intensity range and the spot / flood adjustment.
Symptom: Sterilisable handle loose or not detected
- Inspect the handle mount and its detent / contacts.
- Clean the contacts.
- Fit a known-good handle.
- Replace a worn handle or its mount.
- Confirm detection and secure fit.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
There is a potential the joint in the suspension of the device is insufficiently assembled.
- RECALL
The potential hazard that can arise for the combination of the missing screws and the overloading by the end user is insufficient mount force that causes the equipment to fall.
- RECALL
Potential incomplete final weld on the drop tube flange.
- RECALL
Stryker has become aware that there is a low likelihood of incomplete engagement of the Spring Arm Circlip during service or replacement of the Spring Arm. If the Spring Arm Circlip is not fully seated, the Spring Arm could separate and fall along with the surgical lights or monitors mounted to the end of the Spring Arm. To date, there have been no serious injuries reported from the incomplete e
- RECALL
Stryker has identified a potential structural issue with the Visum LED surgical light(s). During a complaint investigation, Stryker became aware that there was a possibility that incorrect assembly could result in the light head beginning to separate from the suspension arm. In the event the light separates and falls from the arm, it could lead to serious injury.
- RECALL
Installation records for the SwitchPoint Infinity, Booms, Lights, and Flat Panel systems are incomplete or inadequate.
