Stryker SERFAS Energy RF Ablation System
Stryker · Model SERFAS Energy RF Ablation System
SERFAS Energy system and probes offer: • Hand control • Bendable probes • A small, powerful generator • Eleven distinct power levels • Impedance detection technology • RFID technology • Integrated Cable
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.
Instrument / implant breakage
HighSymptoms: Fractured tip, loose component, debris.
Root cause: Metal fatigue, improper reprocessing, or misuse.
Reprocessing / sterilization failure
MediumSymptoms: Residue, bioburden, discoloration.
Root cause: Inadequate cleaning cycle or damaged tray.
Table hydraulic / actuator fault
MediumSymptoms: Slow or drifting positioning.
Root cause: Cylinder seal or actuator wear.
OR light LED failure
LowSymptoms: Dim or dead panel, color shift.
Root cause: LED module aging.

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: Electrosurgical electrode wear
- Confirm the presentation - typically poor cut/coag, sparking, low power - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: burned/eroded blade or pencil.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the electrosurgical pencil & electrode 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: Return electrode / pad fault
- Confirm the presentation - typically pad alarm, no activation - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: poor contact or expired pad.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the return electrode (patient plate) 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.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
A breach in the sterile packaging may have occurred resulting in potentially non-sterile product.
- RECALL
Stryker Endoscopy is recalling all non expired SERFAS 90 degree Energy Probes due to reports of fragments of the probe breaking off into the patient.
- RECALL
When positioning the display located on top of the video cart, it is possible for the user to apply excessive force and push the display up and out of the mounting arm. This can result in the display falling upon the user/patient.
- RECALL
An increased number of complaints for tip breaks were observed for the 3.5mm Super 90-S SERFAS Energy Suction Probes manufactured from June to August 2011.
- RECALL
The probes may have inadequate suction due to obstruction, which can result in unintended ablation due to reduced visibility within the surgical area.
- RECALL
Device Shut off/on: Device may not turn off after taking finger/foot off of activating switch and may activate without pushing a button. (Patient burns may result from these device malfunctions)
