Range hood 1 can firmly be fixed on sealing ring 6 by support 7, effectively prevents range hood 1 from rocking in operation process, affects operation process.
Have space between above-mentioned range hood 1 and sealing shroud 2, space is about 1mm-2mm at sealing ring 6 place, increases gradually, reach 5mm to range hood 1 near the space, one end place of electric knife handle 5 to the one end near electric knife handle 5.
Range hood 1 is being provided with attraction side opening 11 within the scope of electric knife head 4 one end 0-10mm, and the diameter attracting side opening 11 is 2-5mm, number >2.
This utility model effectively can absorb the smog and blood and slime that produce in operation process.The smog produced in electric knife cutting or blood coagulation operation and blood and slime etc. simultaneously from the hole of support 7 with attract side opening 11 to absorb, can be collected through range hood 1 and hard suction catheter 3, ensure that the smog that absorbs generation while using electric knife operation completely and blood and slime etc.
Described device is provided with buckle 8, and wherein, hard suction catheter 3 is closely fastened on electric knife handle 5 by buckle 8, prevents hard suction catheter 3 from moving, and stops user sight line; Range hood 1 is tapered, can avoid the sight line stopping user equally.
Described range hood 1 and support 7 use transparent polythene material, and hard suction catheter 3 uses silastic material.
Whole suction device structure is simple, and do not change existing electric knife, the structure of electric knife head and shape, simultaneously with low cost, it is convenient to change.
Below by way of detailed description of the invention, this utility model is described, but protection domain is not limited to the scheme in embodiment.
