The Neuro N50 lesion generator is an universal device that enables a fast and exact presetting of the selected coagulation temperaure and reproducable lesions by programmed power regulation adapted to the connected instrument type and provides conventional coagulation techniques of minimal invasive pain therapy and neurosurgery. The device adjusts automatically all further functions including the proportioning of the RF performance.Controlled lesion techniques are performed with the helps of the programmed temperature control. All functions of the device and display of all operation errors, defective electrodes or equipment failures are under Microprocessors control . By temperature controlled coagulation, only the coagulation temperature and coagulation duration is preselected. Each intervention should be documented to store values measured and can be displayed graphically on an external printer or a PC. Its applications include -Thermocoagulation of the Ganglion Gasseri and Ganglion pterygopalatinum. It helps in pain therapy interventions at the spinal cord and on an peripheral nerves.
