REM Contact Quality Monitor

  • Interrogation frequency: 80 kHz ± 10 kHz
  • Interrogation current: < 100μA
  • Interrogation voltage: < 12V RMS

Acceptable Resistance Range

  • REM resistance measurements are ± 10% during RF activation and ± 5% when RF output is not activated.
  • REM patient return electrode: 5 to 135 ohms or up to a 40% increase in the initial measured contact resistance (whichever is less).
  • If the measured resistance is outside the acceptable range(s) noted above, a REM fault condition occurs.

REM Alarm Activation

  • REM patient return electrode: When the measured resistance exceeds the standard range of safe resistance (below 5 ohms or above 135 ohms) or when the initially measured contact resistance increases by 40% (whichever is less), the REM alarm indicator enlarges and flashes red and yellow, a tone sounds twice, and RF output is disabled. The indicator remains illuminated red and yellow until you correct the condition causing the alarm. Then, the indicator illuminates green and RF output is enabled.


  • The ForceTriad energy platform is equipped with an autobipolar feature that allows for the automatic activation of bipolar energy.
  • Note: The autobipolar electrode function requires the use of the Valleylab E0018 bipolar Instrument cord.
  • Autobipolar Specificaitons:

    • Interrogation current: < 100 μA.
    • Activation impedance: 20 Ω to 500.
    • Deactivation impedance: User selectable: 1,500 Ω 1,800 Ω or 2,200 Ω.
    • Measurement accuracy: ± 14% of Full Scale activation impedance while keying active above 10 watts.
    • + 50%, -14% of full-scale activation impedance while keying active at 10 watts or below.
    • ± 5% of Full-Scale activation impedance while keying inactive.
    • Keying delay: User selectable in 500 msec increments from 0 sec to 2.5 sec

Duty Cycle

  • Under maximum power settings and rated load conditions, the ForceTriad energy platform is capable of operating a duty cycle of 25% defined as 10 seconds active and 30 seconds inactive, in any mode for a period of 4 hours.
  • Caution
    • Use of duty cycles greater than 25% (10 seconds active followed by 30 seconds inactive) will increase the risk that heat build-up under a return electrode may be high enough to injure the patient. Do not continuously activate for longer than one minute.

The Covidien ForceTriad energy platform is a completely integrated ESU generator for open and laparoscopic electrosurgical procedures. The Force Triad provides surgeons with one generator for electrosurgical and tissue fusion needs. Historically, medical facilities needed separate pieces of equipment to achieve the desired clinical outcome: monopolar, bipolar, and vessel sealing. The ForceTriad unifies each into one simple platform, making it an efficient and powerful tool for the operating room. It offers the surgeon all the features they need, including electrosurgical cutting and coagulation, bipolar function and LigaSure tissue fusion.

Note: This popular advanced energy platform from Medtronic is available professionally refurbished through Avante Health Solutions. More recent manufactured units may have the Covidien brand versus the Valleylab name but is within the same line of technology.

  • All-in-one unit is compatible with common electrosurgical instruments and all current and new LigaSure instruments
  • Fusion cycles are faster than the original LigaSure vessel sealing generator
  • Easy-to-use touch screen setup
  • Reduces demands on staff during procedures
  • Automatic instrument recognition
  • Quick and efficient power and mode adjustments from within the sterile field for shorter procedures.
  • Advanced LigaSure tissue fusion technology permanently fuses up to 7mm vessels, lymphatics, tissue bundles, and pulmonary vasculature
