The Piezo device consists of an external unit that generates energy and a handpiece, resembling a pen, held by the surgeon. Various cutting tips of different shapes and sizes can be attached to the tip of this handpiece for use during surgery. The device functions as an extremely precise and intelligent saw that works on bone. Its most distinguishing feature is its ability to selectively cut only bone, automatically stopping when it encounters soft tissues like muscle and cartilage. This feature ensures maximum precision with minimal damage to surrounding tissues.
