Configuration of Hardware for Medical Plasma Based Surgical Device and Features

摘要

This research, covers the evaluation of the performance of harware of plasma-based (gas plasma, plasma jet) surgical prototype device which will be used in microsurgery, identification of active device operating conditions with the appropriate engineering models Microsurgery is by taking advantage of the magnifying effect of the special operation microscope, very small structures that can hardly be seen with the naked eye and surgery using very thin instrument. It is necessary to emphasize, the plasma technique using on directly liver cell for the treatment is the novel study. The examples of portable commercial devices in the world have started to increase in the recent past, but they are still few. The project has three main design in general; primarily high voltage power supply, bipolar plasma probe, gas supply control unit made it. High voltage power supply made with transformator and mosfets connecting with push-pull. Bipolar plasma probe, made 2 tungsten rod which mounted on the board mechanism and used teflon wire for connection with high voltage power supply. For the gas supply control unit, used microprocessor controlled and transistor amplifier selenoid valve. Thus, it is aimed to trigger the solenoid valve and adjust the gas flow in the adjustable frequency range. In the first tests made, the formation of radiation of the high voltage circuit was observed. The integration with the tungsten probe system was completed and tried to test the relation between angle and distance and radiation. In addition, the completed parts of the gas supply control unit designed together with the solenoid valve and the microprocessor have been tested. etc. in its style sheet. As a result, the distance parameter of radiation formation is determined by high voltage circuit tests. Radiation-angle tests were performed and later turned into a prototype with the outer design of the device.
