Valleylab Force EZ(c) Electrosurgical Generator

The Valleylab Force EZ Electrosurgical Generator has instant response technology that 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." The Force EZ will adjust automatically, responding to tissue changes, maintaining power delivery, and minimizing drag. Instant Response technology will reduce capacitive coupling by 30-50%. This is acheieved by limiting the RMS voltage and the high frequency harmonics.

Features

• Instant Response Technology
• Improved Performance at lower power settings
• Three internal microcontrollers
• Easy to use
