Elmed ESU 100
Elmed · Model ESU 100
• Three RF-solid state circuits. One for unipolar cutting and coagulation in the MICRO or MACRO modes, one for bipolar coagulation, and one for BI-POL CUTTING ESU 100 E M/M-B only). • Accepts all laparoscopic or pelviscopic electrosurgical instruments. • Single pedal footswitch operated, with low voltage switching circuit. • Patient safety circuit. Automatic, low voltage sentry, alarms and deactivates the unipolar output in case of a defect in the connections for the patient plate circuit. Optionally, our Return Electrode Monitor System is available, which also will alarm and deactivate the unipolar output in case of poor patient plate contact. • Change-over switch for unipolar or bipolar operation, defeats the patient plate alarm in the bipolar mode. • Visual and audible RF-indicators. • L.E.D. Bar-graph meter for unipolar wattage. • Low voltage bipolar generator provides reliable coagulation with all available bipolar forceps for laparoscopy, pelviscopy and microsurgery. • Musical coagulation monitor for the bipolar mode provides both audible and visual indication of the degree of tissue coagulation, particularly for bipolar tubal sterilization (Not available on the 100 L). • SMART-O-MATIC, automatic compensation circuit provides the desired output for all electrodes or tissue conditions. The automatic range control, which is divided into ten steps, requires no readjustment within the set range. The SMART-O-MATIC operates in both the unipolar and bipolar modes. • Output intensity may be precisely regulated within the full range of the dial setting. However, investigations have demonstrated 20 W at 100 Ohms achieves optimal results, therefore, we have incorporated a preset selection and 20 W range preselect switch (Not available on 100 L). • All of these ELMED 100 series Electrosurgical Units are designed as table top units. A specially designed cart (List No. 52-5067) is available for these described units and other endoscopic equipment.
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.
Electrosurgical electrode wear
MediumSymptoms: Poor cut/coag, sparking, low power.
Root cause: Burned/eroded blade or pencil.
Return electrode / pad fault
HighSymptoms: Pad alarm, no activation.
Root cause: Poor contact or expired pad.
Reprocessing / sterilization failure
MediumSymptoms: Residue, bioburden, discoloration.
Root cause: Inadequate cleaning cycle or damaged tray.
Foot switch failure
MediumSymptoms: Unintended or no activation.
Root cause: Fluid ingress / worn switch.

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.
