Gyrus ACMI PK SuperPulse
Gyrus ACMI · Model PK SuperPulse
Creates a plasma vapor pocket around the active electrode in a safe, saline environment. Can be controlled to remove and modify body tissues using minimal access techniques. Localized return path through saline – separation of active and return electrodes. Each PlasmaKinetic device has its own built internal identification code. This ID code automatically adjusts the PK generator to the optional output power setting for each device. Comprehensive PK Technology Platform. Safer Saline Procedures. Safer PK energy. Braided Tip "Plasma Cut" electrode for finer fibrous tissue. Spring tip electrode for more aggressive fibrous tissue. Faster Procedures. More Effective Treatment. Focused energy around plasms corona. Low voltage. Gives surgeons a wide range of procedures with maximum power, precision and safety. Excellent hemostasis with no risk of hyponatremia. Reduced risk of obturator nerve stimulation. Precise Tissue Removal for TUIP & Bladder Neck Incisions. Shorter catherization time is ideal for daycare or outpatient surgery. Minimal thermal spread (< 1 mm). Virtually eliminates charring and reduces complications associated with deep-tissue desiccation. Minimizes thermal spread. Virtually eliminates charring.
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.
No or low RF output / high-impedance cut-out
HighSymptoms: No cut / coag effect, "high impedance" or output-error message, output shuts down.
Root cause: Poor electrode contact or a dry field, a damaged handpiece / cable, a return-electrode (REM/NESSY) fault, or an output-stage fault.
Return-electrode (patient-plate) contact-quality alarm
MediumSymptoms: REM / NESSY / plate alarm, monopolar output inhibited.
Root cause: Poorly applied or dried split dispersive pad, a pad-cable fault, or the contact-quality-monitor circuit.
Bipolar / vessel-sealing output fault
MediumSymptoms: Bipolar or sealing output weak, seal cycle will not complete, instrument not recognised.
Root cause: Bipolar cable / instrument fault or the sealing output stage.
Fails calibration / output drifts after a repair
MediumSymptoms: Output power or the REM circuit outside tolerance on the analyser.
Root cause: Output board or REM circuit needs recalibration - anti-static handling required.
Footswitch / handswitch fault
MediumSymptoms: Output will not activate from the pedal or the handpiece.
Root cause: Footswitch or handswitch / cable fault.
Touchscreen / display / boot fault
LowSymptoms: Unresponsive touchscreen, will not power on or boot, fan / thermal alarm.
Root cause: Display, power supply, control board, or a cooling-fan fault.

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: No or low RF output / high-impedance cut-out
- Confirm good electrode-tissue contact and an adequately wetted field.
- Inspect the handpiece / instrument and its cable for damage; substitute a known-good one.
- Check the split dispersive (return) pad is well applied over well-perfused muscle with a sound cable.
- Verify output into a resistive test load with an electrosurgical analyser.
- Replace the RF output board and recalibrate on a non-conductive surface if output is confirmed absent (anti-static handling).
Symptom: Return-electrode (REM / NESSY / CQM) contact-quality alarm
- Re-apply a fresh split dispersive pad with full skin contact.
- Check the pad cable and its connector.
- Try a known-good pad.
- Run the contact-quality-monitor calibration with a good pad fitted.
- Refer the CQM circuit if it still alarms.
Symptom: Output will not activate from the footswitch or handswitch
- Test the other activation method to isolate the pedal from the handpiece.
- Inspect the footswitch and its cable / connector for damage or moisture.
- Check the handswitch leads on the handpiece.
- Substitute a known-good footswitch.
- Refer the activation input board if both methods fail.
Symptom: Fails calibration / output drifts after a repair
- Verify cut and coag output at several settings into a test load with an analyser.
- Verify the REM / CQM circuit against its spec.
- Recalibrate per the service manual on a non-conductive bench with anti-static precautions.
- Check the cooling fan and thermal path.
- Re-verify all outputs and the REM alarm before returning to service.
