Radiofrequency Generator MRFG-01B
Seeking to integrate the new minimally invasive surgical tendencies, Micromar has developed equipment that associates technological solutions to all your needs.
 The MICROMAR Radiofrequency Generator MRFG-01B was designed so that the neurosurgeon can perform several procedures such as cerebral stereotactic thermo-coagulation, trigeminal and facet rhizotomy, mielotomy, DREZ and others with total safety and with a high level of reliability and trust.
With the efficiency of 50W power, it can also perform measurement of impedance and stimulation accompanied with audio indication, RF functioning test, lesion with time control, continuous monitoring of the temperature and voltage and current indication of the RF. It also features a set of appropriate electrodes for each procedure.
Compact and lightweight, it can be easily transported to any surgical environment.
The MRFG-01B meets the international electrical safety norms and requisites: IEC 601-1, IEC 601-2-2, directives 93/42 – CEE "Medical Devices" and 89/336 – CEE "Electromagnetic Compatibility".
The special isolation of the entrance transformer results in a extremely low escape current, thus being designated to the BF class for protection level against electrical shock and class I protection type against electrical shock, being it an equipment powered by an external electrical power source.
The MRFG-01B was designed for short usage periods, and as for the protection level against harmful water penetration it is classified as common equipment (closed equipment without protection against water penetration).
The parts applied to the patient are isolated from the ground wire and protection.
Its retractable feet insure a better positioning of the equipment.
All the functions are conveniently displayed on a panel on the Radiofrequency Generator system MRFG-01B in order to allow that the neurosurgeons have complete control over all the adjustment parameters without complications.
"Auto test"
Verifies the generation of radiofrequency, insuring perfect functioning throughout surgeries.
"RF Mode"
This mode allows the performing of thermal lesion procedures.
"Stimulation"
All the stimulation parameters can be adjusted in a precise way, insuring complete control of the desired functions.
"Timer"
Digital countdown insures perfect visualization of lesion time.
