description Disclosed is a tool bit for an ultrasonic osteotome, including a bit body (1) connected with an ultrasonic equipment, an arbor (2) fixed to the bit body (1), and a flat end portion (3) of the tool bit fixed to the arbor (2). End portion (3) of the tool bit includes a toothed edge (4) extending linearly along a length direction of end portion (3) of the tool bit, and a plurality of recesses (5) are distributed evenly on toothed edge (4) to form teeth (6) spaced apart from each other. According to the present invention, toothed edge (4) of end portion (3) extends linearly along a length direction, the cutting edges of teeth (6) are distributed linearly instead of having a sharp structure, thus will not scrape and hurt other tissues during cutting. Since the thickness of the cutting edge is set to be the same as that of the back edge, when cutting bone tissues, the incision is wide and thus the end portion is not easy to be clamped by the bone tissues, which effectively prevents the end portion from breaking and reduces occurrence chances of surgery accidents.
