Surgical smoke, a byproduct of electrosurgical procedures, contains harmful particulate matter (PM) and volatile compounds, posing health risks to medical personnel. This study explores a dielectric barrier discharge (DBD) plasma system to trap PM from surgical smoke, emphasizing the effects of varying inner and outer electrode configurations. Using an acrylic tube, copper electrodes, and high-voltage alternating current, the system generated plasma by ionizing air between electrodes. The system's effectiveness was tested by measuring PM levels at varying voltages (9-13 kV) using an aerosol monitor while cutting tissue with an electrosurgical unit. Results demonstrated that higher voltages enhanced PM trapping efficiency due to increased plasma interaction and electric forces acting on PM particles. The 18 mm copper inner electrode and a copper plate outer electrode achieved the highest efficiency, attributed to its more substantial and uniform electric field. In contrast, other electrode configurations showed reduced PM trapping efficiency due to inconsistent plasma formation. Findings highlight the potential of DBD plasma systems in improving surgical smoke evacuation, paving the way for integration with commercial systems to safeguard operating room personnel.
