Radiofrequency electrosurgery uses high-frequency electrical energy to cut or coagulate tissue with precision.
Radiofrequency Electrosurgery
This frequency allows minimal thermal damage to surrounding tissue, promoting better healing and reduced trauma.
Technology
What is Electrosurgery?
Electrosurgery is a surgical technique that uses high-frequency electrical current to cut, coagulate, or modify biological tissue. In conventional electrosurgery systems operating in the range of 330–500 kHz, tissue interaction is associated with higher impedance and greater thermal spread compared to higher-frequency systems.
At 4 MHz, electrosurgical energy is considered more atraumatic because tissue impedance decreases as frequency increases. Biological tissue behaves predominantly as a capacitive medium, meaning its impedance is inversely related to frequency. As a result, higher frequencies allow more efficient energy transfer with reduced collateral thermal damage.
Comparative observations show different impedance behaviors in various tissue types such as skin, fat, and muscle, where each responds differently due to variations in water content and structure. Skin typically shows higher impedance, fat even higher due to low conductivity, while muscle has lower impedance because of higher water and electrolyte content.
Due to the lower impedance at higher frequencies, the same output power can be achieved with a lower required voltage, resulting in more controlled energy delivery and improved precision during surgical procedures.

Advanced Electrosurgical Technology
About RWSU Proxima
Proxima RWSU is a medical technology company specializing in advanced radiofrequency electrosurgery systems designed to deliver precision, safety, and improved surgical outcomes. Our solutions are based on high-frequency electrical energy that enables cutting, coagulation, and tissue modification with exceptional control and minimal thermal impact on surrounding structures.
Unlike conventional electrosurgical systems operating in lower frequency ranges (330–500 kHz), Proxima RWSU technology operates at significantly higher frequencies, including 4 MHz. At this frequency range, biological tissue exhibits lower impedance due to its capacitive behavior, allowing more efficient energy transfer and reduced collateral thermal damage.
Adaptive Performance in Biological Tissue
This results in a more atraumatic surgical experience, where surrounding tissue is preserved, healing is enhanced, and patient recovery is improved. Different tissue types—such as skin, fat, and muscle—respond uniquely to electrical energy based on their composition and water content, and our systems are engineered to optimize performance across these variations.
