IMPROVEMENT ELECTRODES OF ELECTROSURGICAL REUSABLE TOOLS
Wide introduction into medical practice of welding technology requires the development of a reusable electrosurgical tool. The problems of tissues adhesion to surfaces of the electrodes of the electrosurgical instruments during the flow of high frequency current and uneven heating of the contact surfaces of these electrodes are considered. These problems solved using copper-molybdenum pseudo alloy, which allows obtaining improved physical and mechanical characteristics of the material of the electrodes. Uniform distribution of fine pores present in the structure of the copper-molybdenum pseudo alloys. The choice of the optimal percentage of molybdenum content substantiated. The use of this technology allows obtaining material for electrodes reusable electrosurgical instruments, which meets the highest medical requirements. Lack of adhesion of biological tissue to the Cu-Mo material of the electrodes checked by 5mm diameter pig’s artery welding. Evaluation of the biocompatibility of this pseudo alloy with biological objects (lab rats and rabbits) showed the absence of both internal and external pronounced sensitizing effect.
