1. An ultrasonic osteotome bit for cutting bones, comprising a bit bar, a bit body and a bit tip, with a first end of the bit bar being connected to the bit tip, and a second end of the bit bar being connected to the bit body, wherein:
the bit tip is of a straight prism or substantially straight prism shape with a cross section of a polygonal shape, and
the bit tip has at least two cutting faces with different cutting widths, which are formed by at least one side face of the straight prism or substantially straight prism shape and through which the ultrasonic osteotome bit is operable to generate at least two incisions of different widths in a cutting object, wherein the at least two cutting faces extend from a foremost end face of the bit tip towards the bit bar, and wherein a shortest distance among distances between respective opposite sides of the polygonal shape is not equal to a longest distance among distances between respective opposite sides of the polygonal shape, and the two opposite sides having the shortest distance are perpendicular to the two opposite sides having the longest distance so that the bit tip has at least two cutting widths.
