Stryker TPS
Stryker · Model TPS
Total Performance Arthroscopy Shaver Console Works with the Stryker 12K Shaver Handpiece.
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.
Handpiece motor / coupling wear
HighSymptoms: Weak or stalled blade rotation.
Root cause: Motor brush wear or drive coupling fatigue.
Console circuit board fault
HighSymptoms: Console won't power on, or resets mid-case.
Root cause: Main board or power supply failure.
Footswitch / console control fault
MediumSymptoms: No response, or intermittent activation.
Root cause: Worn footswitch pedal or connector.
RF electrode connector wear (RF-equipped consoles)
MediumSymptoms: Arcing, or no RF output.
Root cause: Worn electrode connector contacts.

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: Handpiece motor / coupling wear
- Confirm the presentation - typically weak or stalled blade rotation.
- Check the most likely cause first: motor brush wear or drive coupling fatigue.
- Inspect the affected subsystem against the manufacturer's inspection checklist.
- If the fault is confirmed and not a field adjustment, service or replace the handpiece motor 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.
Symptom: Console circuit board fault
- Confirm the presentation - typically console won't power on, or resets mid-case.
- Check the most likely cause first: main board or power supply 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 blade / burr coupling 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.

It was discovered that the silicone potting failed to properly cure after undergoing the prescribed curing possess. The potting material is used to insulate, stabilize and provide a moisture barrier to the TPS MicroDriver main Printed Circuit Board Assembly (PCBA). Inadequate cure of the silicone potting could potentially allow it to leak to the outside of the handpiece or cause an electrical ma

The safety margin values detailed in the Engineering Design were entered incorrectly into the programming software. Handpieces that have been programmed with the incorrect parameters could result in unintended activation. There is a potential for injury to the patient or user as a result of unintended forward or reverse activation. There is also the potential that the handpiece may not reach 100
- RECALL
There is a potential for these blades to break where the blade is welded on to the arbor. This hazard can result in the following harms: tissue damage due to the broken blade being aspirated or swallowed, additional surgery to remove a broken blade, infection due to an unretrieved device component, complications associated with increased time under anesthesia to retrieve a broken blade, osteomyeli
- RECALL
Product was packaged with an incorrect packaging material and therefore has a potential to be non-sterile which, if contaminated, could lead to a patient infection.
- RECALL
Lack of assurance of sterility.
