Outdated Article
ELECTROSURGICAL UNIT (Force FX)
Stopped in 2019 because no longer manufactured. Replacement by Lamidey SEAL (see “replaced by” at bottom of the page).
Definition
An assembly of devices intended to generate, and apply radio-frequency (RF) alternating current to soft tissues for cutting and coagulation during an endoscopic or open surgical procedure; it is not dedicated to focal ablation of specific tissues. Tissue resistance to the electrical current creates the heat as the current travels through the body between electrodes
The assembly includes
- a mains electricity-powered RF generator with monitoring functions/controls
- connection cables
- a handpiece with electrodes to apply the energy to the surgical site
- a patient return electrode is necessary for monopolar electrosurgery
Specifications
The Valleylab Force FX™ is an isolated output electrosurgical generator that provides the power for cutting, desiccating, and fulgurating tissue during surgery. The generator is used for bipolar and monopolar electrosurgical procedures.
The generator features computer controlled Instant Response Technology designed to ensure a consistent clinical effect through all tissue types.
You can use handpiece or footswitch controls to activate the generator.
Receptacles are marked to ensure the correct connection of accessories.
Indicators alert you when the generator is activated.

Technical specifications
Electrosurgical system generator
Isolated generators isolate the current from ground and do not allow significant current to seek alternate paths to ground. The current must return through the patient return electrode to the generator.
- Operating parameters:
- Temperature range: 10°C to 40°C (50°F to 104°F)
- Relative humidity: 30% to 75%
- Atmospheric pressure: 700 to 1060mbar
- Input
- Operating range is 85 to 132 AC volts.
- Maximum current is 7 amperes in "Cut" and 4 amperes in "Coagulation"
- Output:
- 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 Coagulation
- Desiccate: 240 kHz sinusoid repeated at 39 kHz. 8% duty cycle.
- Fulgurate: 390 kHz damped sinusoidal 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 21kHz < 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).

Instructions for use
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 coagulation 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 settings utilize low voltage to prevent sparking
Precautions for Use
To be used by qualified staff only.
Read the manufacturer's notice carefully.
The patient return electrode has to be applied as widely as possible on the patient's bare skin and as close as possible to the surgery field.
Secure the electrical protection of the apparatus with a double conversion UPS (see related articles below).
CAUTION, DANGER OF BURN:
- if the contact surface between the return electrode and the patient is too small (current concentration)
- if the plate is not always dry (liquids are electric conductors)
MSF requirements
Electro surgical generator, used in surgery for the cutting of soft tissues and coagulation. Article selected for two of its functions: monopolar cutting and coagulation (for general surgery).
Easy to use and compact, it ensures all safety required for high quality electrosurgical units.
