CURIS® - Microsurgical Radiofrequency Generator
The microsurgical radiofrequency generator CURIS® made by Sutter Medizintechnik in Germany relies on the 4 MHz technology: It is gentle to the tissue and effective for coagulation, for lesions and for cutting. The patient trauma is reduced to a minimum.
4 MHz Technology
The higher the frequency, the less the resistance of biological tissue to electromagnetic fields – up to the point where the cell membranes are capacitively coupled. This is exactly what happens with the 4 MHz produced by the CURIS® (both in the monopolar and the bipolar modes).
The electromagnetic fields are active in the tissue cells – not as is the case with conventional electrosurgical units, between the cells.
As a result energy is administered gently and in a highly focussed fashion. For example precise monopolar cuts are possible while lateral heat damage is kept to a minimum.
p3™ is active in all coagulation modes of the CURIS®. Radiofrequency energy is delivered in small packages of about 50 per second.
Due to the pulsed power output, there are very short breaks between the individual packages. The tissue has the time to absorb and distribute the energy and will generally be less traumatised. Highly-focussed, yet gentle coagulation with
minimal thermal damage is possible. The p3™ process is, of course, AutoRF™ controlled.
Precision thanks to AutoRF™
The AutoRF™ function is the main control feature of the CURIS®. It responds to tissue impedance in all modes and controls and adjusts the power output according to tissue resistance.
The AutoRF™ function of the CURIS® will tailor the energy output (if need be even cut off or drive to the chosen maximum) in order to to ensure reproducible surgical results during cutting or coagulation.
