Covidien ValleyLab Force FX-C

Covidien Valleylab FX-C Features

The Covidien Force FX-C is an electrosurgical generator, also referred to as the “Covidien Force FX electrosurgical generator C ” , that provides isolated output power for cutting, desiccating, and fulgurating tissue during bipolar and monopolar surgery.

• Instant Respons technology ensures that the power delivered remains virtually constant, regardless of the tissue type
• Improved performance at lower power settings minimizes the risk of tissue damage and neuromuscular stimulation
• Three internal microcontrollers reduce system reaction time and increase the system’s processing speed
• Spray coagulation voltage of no more than 9000 volts peak-to-peak output for broad, but superficial coagulation with limited capacitive coupling
• A Power Efficiency Rating (PER) of approximately 98 for accurate and consistent cut performance
• Three cut modes, all controlled by Instant Response™ technology, offer surgeons a variety of choices:
  • Low Cut for delicate tissue or laparoscopic cases
  • Pure Cut for a clean, precise cut
  • Blend for cutting with hemostasis
• Four coag modes:
  • Desiccate for low voltage contact coagulation suitable in laparoscopic and delicate tissue work
  • Fulgurate (high crest factor) for efficient noncontact coagulation in most applications
  • Fulgurate (low crest factor) for lower voltage coagulation requirements
  • Spray for coagulating large tissue areas with superficial depth of necrosis
• Three bipolar modes:
  • Precise, Standard, and Macrobipolar are controlled by the Instant Response™ system
  • Precise and Standard setting utilize low voltage to prevent sparking
• Versatile system that is uniquely compatible with other devices, including:
  • Force Argon™ II and Force GSU™ argon coagulation system
  • CUSA EXcel™ and CUSA™ 200 ultrasonic surgical aspirators
  • OptiMumm™ smoke evacuator, through a direct cable link
  • Valleylab VLCM bipolar current monitor
• Compatible with and used as the electrosurgical energy source for:
  • Dyonics* Control RF arthroscopic ablation system
  • Dyonics* Electroblade™ rotary resection system
  • Cook Vascular Perfecta™ EDS pacemaker lead extraction system
• Compatible with, and the exclusive electrosurgical generator for, the Computer Motion Hermes™ Voice Command system

Output Waveforms

• Bipolar
  • Precise: 470 kHz sinusoid
  • Standard: 470 kHz sinusoid
  • Macro: 470 kHz sinusoid
• Monopolar Cut
  • Low: 390 kHz sinusoid. Similar to the Pure Cut mode except the maximum voltage is limited to a lower value.
  • Pure: 390 kHz sinusoid
  • Blend: 390 kHz bursts of sinusoid, recurring at 27 kHz intervals. 50% duty cycle envelope.
• Monopolar Coag
  • Desiccate: 240 kHz sinusoid repeated at 39 kHz. 8% duty cycle.
  • Fulgurate: 390 kHz damped sinusoid bursts with a repetition frequency of 30 or 57 kHz into 500 ohms.
  • Spray: 390 kHz damped sinusoidal bursts with a randomized repetition centered at 28 kHz. Frequencies include 21 kHzz < f < 35 kHz. Output is further modulated by a random 250 Hz envelope with a variable duty cycle.
• Output power changes by less than 15% or 5 watts, whichever is greater, as the line voltage varies from 104-132 volts and 208-264 volts (at rated load).

Low Frequency Leakage

• Source current, patient leads, all outputs tied together.
• Normal polarity, intact chassis ground: < 10 µA
• Normal polarity, ground open: < 50 µA
• Reverse polarity, ground open: < 50 µA
• Sink current, 140V applied, all inputs: < 50 µA

Input Power Requirements

• Operating range is 85 to 132 AC volts. Maximum current is 7 amperes in Cut and 4 amperes in Coag.

Rem Contact Quality Monitoring System

• Measurement Frequency: 80 kHz ± 10 kHz
• Measurement Current: Less than 10 µA
• Acceptable Resistance Ranges:
  • REM™ pad – 5-135 ohms
  • Non-REM™ pad – less than 20 ohms
• Acceptance range is 5-135 ohms after REM PolyHesive II return electrode is applied.
• Adaptive REM: REM trip is baseline impedance plus 40%. For example, if the baseline impedance is 30 ohms, the upper-level trip approximately 42 ohms. If the pad-patient impedance falls below the baseline impedance, a new baseline is established.
