Large sternum blades are surgical instruments designed for use in procedures involving the chest or sternum, such as cardiac surgery and thoracic surgery. The term "sternum" refers to the breastbone, and these blades are specifically shaped for cutting or splitting the sternum, allowing access to the thoracic cavity. Large sternum blades, as the name suggests, are larger versions of these instruments, suitable for cases where a more substantial incision or dissection is required.
