ValleyLab Force FX

The ValleyLab Force FX with instant response technology provides surgeons with improved performance at lower power settings, minimizing the risk of tissue damage and neuromuscular stimulation, and decreasing the need to “turn up the generator.”

A Smoother Cut Through All Tissue Types
The Force FX generator adjusts automatically, responding to tissue changes, maintaining power delivery, and minimizing drag.

Added Safety and Reliability Minimizes Electrosurgical Risks
Capacitive coupling is reduced by 30-50% when using Instant Response technology. This reduction is achieved by limiting the RMS voltage and the high frequency harmonics. Lower voltage means less neuromuscular stimulation and more precise delivery of energy to reduce collateral damage.

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.
