    摘要： A gas-enhanced electrosurgical generator. The gas-enhanced generator has a housing, a first gas control module in the housing and configured to control flow of a first gas, a second gas control module in the housing and configured to control flow of a second gas, a high frequency power module, and a controller, processor or CPU within the housing and configured to control the first gas control module, the second gas control module and the high frequency power module. The first gas and second gas may be any of CO2, argon and helium or another gas. The gas-enhanced electrosurgical generator may have a third gas control module in the housing and configured to control flow of a third gas and a third connector secured on an exterior of the housing.

    摘要： An integrated gas-enhanced electrosurgical generator. The generator comprises a high frequency power module, a low frequency power module and a gas module. The high frequency power module adapted to generate an electrical energy having a band of frequencies centered around a first frequency, wherein the electrical energy has a first power as the first frequency and a second power lower than the first power at a second frequency lower than the first frequency. The low frequency power module having an input connected to an output of the high frequency module. The low frequency module comprises a resonant transformer comprising a ferrite core, a primary coil and a secondary coil, the secondary coil having a larger number of turns than the primary coil, wherein the resonant transformer has a resonant frequency equal to the second frequency. The gas module is adapted to control a flow of an inert gas.

    摘要： A cold plasma accessory having a hand piece having within in it flexible tubing, wiring, a PCB board connected to the wiring, and a conductive connector tube electrically connected to the PCB board, the conductive connector tube having an inner channel, a rigid tube extending from the distal end of the hand piece, and an electrode within the rigid tube. The electrode comprises a conductive connector having a contact surface contacting the conductive connector tube, a distal end surface facing away from the conductive connector tube, and a channel extending through a center of the conductive connector, the channel being fluidly connected to the flexible tubing, the distal end surface of the conductive connector being outside of the channel in the conductive connector, and a conductive wire connected to the distal end surface of the conductive connector.

    摘要： A method for elevating a TRAIL-R1 expression in cancer cells to induce apoptosis. The method comprises the steps of receiving electrical energy having a specific voltage, frequency and power from an electrosurgical generator, up-converting the voltage and down-converting the frequency with a high voltage transformer having a primary coil and a secondary coil, the secondary coil having a larger number of turns than the primary coil, applying said converted electrical energy to an electrode in an electrosurgical hand piece, flowing an inert gas through said electrosurgical hand piece to produce a cold plasma at a distal end of said electrosurgical hand piece; and applying said cold plasma to cancer cells for 1 to 3 minutes. The inert gas may comprise, for example, helium or argon. In a preferred embodiment the cold plasma is applied to cancer cells for about 2 minutes.
