Osteotome

An osteotome is an instrument used for cutting or preparing bone.

[1] Osteotomes are similar to a chisel but bevelled on both sides.

[2] They are used today in plastic surgery, orthopedic surgery and dental implantation.

[3] The chain osteotome, originally referred to simply as the osteotome, was invented by the German physician Bernhard Heine in 1830.

[4][5] This device is essentially a small chainsaw.
