Abstract

In this study, to solve the problem of harmful gases in laparoscopic surgery, the filtration efficiency of a meltblown nonwoven filter modified with hydrocharging treatment according to the change in basis weight was investigated. Experiments were conducted with both 35 GSM (M35) and 40 GSM (M40) using NaCl 32 LPM, and the resulting efficiencies were 99.312% and 99.973%, respectively. A composite filter with granular activated carbon (GAC) attached based on 20 GSM (M20) was also studied. The evaluation was confirmed when H13 and H14 grade HEPA filters were laminated with 99.993% and 99.995% filtration efficiency, respectively, on a C filter. In addition, to confirm the effect of moisture, experiments were conducted through four cycles after soaking in water and drying. As a result, all nonwoven fabrics showed a slight effect due to hydrocharging, and the HEPA grade could be maintained. However, GAC entering the composite filter confirmed the deodorant effect with an ammonia removal rate of 95.2%, and removal rates of 99.5%, 98.5%, 98.5%, 89.2%, and 95.9% for hydrogen sulfide, trimethylamine, acetaldehyde, toluene, and formaldehyde, respectively, were obtained. When the structure of such a composite filter was integrated with the module of a new type of trocar, the performance of the highly efficient filter was maintained without being affected by the clinical surgical activity radius during laparoscopic surgery. Finally, a basic study of the applicability of new surgical trocars for the removal of harmful gases was conducted.
