Disclosed is a bendable osteotome (chisel) for use in cutting of bone during spine surgery under observation with use of a speculum, wherein cutting of bone can be easily conducted in the bending direction of a blade. This osteotome is characterized in that a portion to be hammered is projected from the middle portion or the end of a handle and so extended along the extension line in the direction opposite to a blade so that the blade edge of the osteotome can easily advance in the direction of the blade even if the portion to be hammered is hammered in a state where the blade edge is not stabbed into a bone, and slippage thereof on the surface of the bone can be reduced. |
