摘要： A power supply device for a high-frequency treatment instrument includes an output section, a characteristic detector, and a stop signal generator. The output section outputs power having a first frequency supplied to the high-frequency treatment instrument. The characteristic detector detects a characteristic signal generated before the power outputted from the output section becomes excessive, the characteristic signal having a second frequency higher than the first frequency and being included in a signal related to the power. The stop signal generator outputs a stop signal to stop or reduce an output of the power from the output section when the characteristic signal is detected.

摘要： A system and method for return electrode monitoring are provided. The system includes an isolation circuit, a first controller, a second controller, and a detection circuit. The isolation circuit includes a transformer having a primary winding and a secondary winding. The first controller is coupled to the primary winding. The second controller and the detection circuit are coupled to the secondary winding. The detection circuit includes an interrogation signal circuit, a resonant tank filter, and a current-to-voltage converter. The interrogation signal circuit provides an interrogation signal to at least one electrode pad. The resonant tank filter filters a response signal received from the electrode pad. The current-to-voltage converter generates a voltage signal based on a current value of the response signal. The second controller generates a digital impedance value based on the voltage signal, and provides the digital impedance value to the first controller by way of the isolation circuit.

摘要： A medical device system and method provide an RF electrosurgical generator coupled to an electrosurgical electrode via a patient box disposed in close proximity to the patient. An RF signal is delivered from the generator to the patient box where signal power is increased and the RF signal delivered to the electrosurgical electrode. The patient box is coupled to the electrosurgical electrode by a short cable capable of carrying an HV, high frequency 5 MHz signal without leakage. An electrical characteristic associated with the electrosurgical electrode is monitored and a desired RF power output and duty cycle maintained by adjusting DC input voltage applied to an RF amplifier, responsive to the monitoring. The system determines when the electrosurgical cutting electrode has started cutting and switches from a start mode to a run mode having a different RF duty cycle and a reduced RF power output controlled by a servo system.
