Abstract: An ultrasonic scalpel includes a scalpel body, a scalpel rod, and an ultrasonic generator, where an annular conductive part, the ultrasonic generator, and an elastic conductive part are arranged in the scalpel body; the scalpel rod is connected to an output terminal of the ultrasonic generator; and the annular conductive part and the scalpel body are connected to each other. An intermediate shell is arranged to fixedly engage with an outer side of the ultrasonic generator; a mounting hole which fits the elastic conductive part is provided in an outer side of the intermediate shell; and the elastic conductive part is electrically connected to the ultrasonic generator and the annular conductive part respectively.
