Dornier MedTech Medilas H 20
Dornier MedTech · Model Medilas H 20
Enhanced Targeting - The laser is equipped with a green aiming beam which aids in targeting and is easily seen during procedures. State-of-the-Art Display - The state-of-the-art, touch sensitive color screen aids in the viewing of display controls. The bi-modal screen allows flexibility for individual user preferences. In addition, the system is designed with user-definable protocol setting. Treatment Control - The distinctive accelerator foot pedal allows treatment flexibility by providing the operator the ability to change the pulse frequency. Adding pressure to the foot pedal will increase the pulse frequency and decrease treatment time. Effective Lightguides - Dornier uses the latest fiber technology for the Medilas H 20. The special design provides maximum transmission of the energy to the stone for enhanced therapeutic effectiveness while protecting the sensitive input optics of the laser. The result is effective treatments and increased reliability of the system Applications. Fragmentation of uteteroliths and kidney stones. Cystolithotripsy of large urinary calculi. Intrarenal neoplasms. Uretal and urethral strictures. Bladder tumors. Pulmonology. Gastroenterology. Gynecology. ENT. General Surgery.
Key tips
- ·When no category-specific guidance fits, default to the manufacturer's own service manual and the general troubleshooting method in the Engineer's Guide.
- ·Run an incoming and annual electrical safety test regardless of how niche the device is.
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 laser output
HighSymptoms: Weak or no Ho:YAG output at the fibre, treatment ineffective, power not reaching the set value.
Root cause: Laser rod / flashlamp aging, a damaged delivery fibre, or a resonator alignment / power-supply fault.
Cooling / thermal shutdown
HighSymptoms: Unit shuts down after a period, over-temperature or low-flow alarm.
Root cause: Coolant low, a chiller / pump fault, or a fouled heat exchanger.
Delivery fibre fault
MediumSymptoms: Burn marks at the fibre tip, high loss, intermittent output, fibre-break alarm.
Root cause: Damaged or contaminated fibre / connector.
Footswitch / interlock fault
MediumSymptoms: Laser will not fire, key / interlock / footswitch error.
Root cause: Footswitch, door interlock, or key-switch fault.
Aiming beam fault
LowSymptoms: No or dim aiming beam.
Root cause: Aiming-beam diode or alignment.

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.
- ·Follow the manufacturer's PM schedule
- ·Perform incoming and annual electrical safety testing per facility biomedical program
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 output
- Measure output at the fibre tip with a power meter against the setting.
- Fit a known-good delivery fibre.
- Check the coolant level and that the chiller runs.
- Confirm the key, interlock and footswitch are satisfied.
- Replace the flashlamp; escalate a rod / resonator fault to Dornier and recalibrate power after service.
Symptom: Thermal shutdown
- Confirm the coolant level and the chiller / pump run.
- Replace the deionising filter.
- Clean or service the heat exchanger.
- Let the unit cool and restart.
- Monitor for recurrence during a treatment.
