Meanwhile, when the circulation smoke exhaust mechanism 100 inflates the abdominal cavity of the patient, the flushing module of the disposable flushing aspirator 300 can also flush the wound, and carbon dioxide gas enters the abdominal cavity of the patient again after entering the smoke circulation filter 200 through the smoke exhaust channel 108 of the circulation smoke exhaust mechanism 100, so that a closed gas circulation channel is formed, and a clear and stable operation visual field is provided for the endoscopic surgery.
In the description of the embodiments of the present invention, it should be further noted that unless otherwise explicitly stated or limited, the terms "disposed" and "connected" should be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in a specific case to those of ordinary skill in the art.
