DUAL-RF 120 Radiofrequency Electrosurgical Unit

Technical Principles of the Radiofrequency

Traditional high-frequency electrosurgical units (with an operating frequency of approximately 300-500 kHz) primarily rely on high-temperature resistive heating to cut tissue. This method is prone to causing tissue carbonization (charring) at the cutting margins and deeper thermal damage. In contrast, the 4.0 MHz and 1.7 MHz ultra-high-frequency radiofrequency (RF) waves utilized by the Dual-RF 90 operate on a completely different mechanism. These ultra-high-frequency electromagnetic waves act directly on the water molecules within tissue cells, causing them to oscillate at high frequencies and vaporize instantly, thereby achieving "low-temperature cutting and coagulation." This physical characteristic—where "higher frequency results in lower operating temperature"—is the core guarantee that enables the RF scalpel to effectively control thermal damage and achieve minimally invasive results.

Core Technology and Clinical Applications

The design of the Dual-RF 90 focuses on controlling intraoperative thermal damage through precise energy output, thereby supporting routine postoperative recovery and pathological analysis.

Superior Postoperative Tissue Outcomes: Thanks to the aforementioned low-temperature operating environment, the dual-frequency RF technology significantly reduces the lateral spread of thermal energy to surrounding healthy tissues. This effectively prevents excessive thermal burns and carbonization, thereby facilitating patient wound healing.
High-Quality Pathological Specimens: By minimizing tissue destruction caused by high temperatures, the device excellently preserves the physical marginal morphology of cells during cutting. This provides the pathology department with high-definition histological specimens free from significant thermal artifacts.

Clinical outcomes for your patients

•Excellent Cosmetic Results – causes minimal scar tissue
•Quick Recovery – with less tissue destruction, healing is hastened and your patients can recover quickly
•Decreased Postoperative Pain – high frequency RF surgery causes less trauma
•Less Burning or Charring of Tissues – high frequency RF surgery minimizes burning of tissue, unlike laser or conventional electrosurgery
•Minimal Heat Dissipation – maximum readability of histologic specimens
