Bone cutter

Types of medical bone cutters include:

Unpowered
Unpowered bone cutting implements include the variety of hacksaw and Sabre saw. In many applications, the saw is used in specialised jigs to provide accurate, measurable cuts, eg Knee Surgery.

Reciprocating
Usually a powered rotary oscillation is applied to a specialised cutting implement to provide smooth controllable cuts into bone, for applications, from skull cutting to rib cutting. A sternal saw is a reciprocating bone cutter.

Sonic, or Sound Cutting
Still experimental, but its primary focus is to use high frequency, high amplitude sound to remove material (in this case bone), providing the ability to cut.
