What is Instant Response? Technology?
Instant Response? technology features an advanced feedback system that recognizes changes in tissue 200 times per second, and adjusts voltage and current accordingly to maintain appropriate power. This unique capability differentiates Instant Response? generators from any other, as shown by their high power efficiency rating (PER). That’s smart? generator technology.

PER indicates the ability of a generator to accurately deliver the selected power into a wide range of tissue types. With a PER of 98, the Force FX? generator provides a consistent surgical effect and has a higher PER than any other electrosurgical generator.

Instant Response? Technology provides consistent power through different tissue types.
The Force FX? generator provides surgeons with the advantage of accurately delivering the selected power setting, even through resistant tissue.

When a conventional generator encounters tissue changes, both power delivery and cutting efficiency are reduced. This means that higher power settings are required in order to cut through all types of tissue. With higher power settings, more energy is delivered, and tissue damage increases.

Features
Instant Response? 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

Monopolar Coag
Desiccate: 240 kHz sinusoid repeated at 39 kHz. 8% duty cycle.

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 (50-60 Hz) Source current, patient leads, all outputs tied together.
