The utility model relates to an ultrasonic tumor suction apparatus, which comprises a main machine and an emulsifying handle, wherein, the main machine is connected with the emulsifying handle by a cable, a liquid injection pipe, and a suction pipe; a variable-amplitude rod is connected to the emulsifying handle. The utility model is characterized in that the variable-amplitude rod is combined with a bent type suction head. Because the bent type suction head of the utility model adopts a bent type structure, during an operation, the sight of a doctor can not be baffled by an operating handle for facilitating the doctor to observe operative sites, and for providing the operation quality. Compared with the existent suction apparatus, the fatigue of the doctor is lightened in a certain extent.
