What is sternum saw?

A sternum saw is a surgical tool used to cut through the sternum (breastbone) during open-heart surgery or other thoracic surgery. It is also known as a sternal saw or bone saw. The saw is typically powered by an electric motor and has a blade specifically designed to cut through bone. The saw is inserted into the chest cavity through an incision made along the midline of the chest and is used to cut through the sternum to allow access to the heart or other organs. The saw blade may be straight or curved, and the instrument may be handheld or mounted on a support stand. Careful use of the sternum saw is necessary to minimize the risk of injury to the surrounding tissues and organs.
