The BoneScalpel is precise enough to cut a window in the shell of a raw egg and yet leave the thin membrane that surrounds the egg white intact. The BoneScalpel has been hailed by surgeons as one of the most important advances in spinal surgery in the last few years. It vibrates 22,500 times a second which allows it to cut through bone but as it bounces off soft flesh it leaves the blood vessels, nerves and other delicate tissues undamaged.

A neurosurgeon specialising in tumour surgery has said that he found significant advantages using this piece of equipment as it allows for less trauma and risk to the patient during surgery. The instrument allows surgeons to make very precise cuts adjacent to critical structures such as the spinal cord. It makes operations quicker, reduces blood loss to almost zero and is a lot safer when operating near delicate structures.
