Abstract
With the wide application of electronic surgical equipment, the generation of surgical smoke is inevitable. Surgical smoke will not only obstruct the operator's visibility, but also release toxic and harmful substances into the air, which will make the operator a headache and cause inflammation of the eyes and mucous membranes. In order to evaluate whether the existing operating room ventilation system can give priority to control the diffusion of surgical smoke, it is necessary to understand the generation, release, transmission and elimination performance of surgical smoke. This paper studied the rule of the influence of surgical smoke in different areas of the operating room through experiments, and verified by the three-area heterogeneous model. At a static state, the cleanliness level of the operating area and the surrounding area is ISO4 and ISO6. When there is staff activity, the operating room is in a dynamic state, and the operating area and the surrounding area are ISO7. When there is surgical smoke, the cleanliness level of the operating area is reduced to ISO8, and the surrounding area has little influence. This indicates that personnel activities and surgical smoke in the operating room have a great impact on the operating room environment.
