AI Technical Summary
Existing electrosurgical pen smoke extraction devices cannot effectively purify the smoke, resulting in toxic chemicals and biological particles in the smoke posing a threat to the health of medical staff.
A multi-functional electric scalpel pen was designed, comprising a metal filter layer, an activated carbon filter layer, and a HEPA filter layer inside the filter tube, for purifying the extracted smoke. The position and angle of the smoke extraction tube can be adjusted by adjusting the adjustment component and the gooseneck tube to stably extract the smoke.
It achieves efficient filtration of flue gas, ensuring the safety of the discharged flue gas, and through the design of the regulating component and gooseneck tube, it ensures stable absorption and precise lighting effect under different operating environments.
