[0002] As is known, in clinical surgical operations, electric knives are frequently used instruments. Electric knives are also called high-frequency electric knives. They are surgical electric instruments that replace mechanical scalpels for tissue cutting. It heats the tissue when the high-frequency high-voltage current generated by the effective electrode tip contacts the body, separates and coagulates the body tissue, and thus achieves the purpose of cutting and hemostasis. However, current electric knives will generate smoke during use, which affects the surgical field of view, pollutes the environment, is inconvenient for the surgeon to operate, and affects human health. In order to promptly remove the smoke generated during the use of the electric knives and the blood oozing out after the patient's tissue is cut, the surgeon himself or his assistant needs to cooperate, and the handheld negative pressure aspirator moves with the electric knives.
