Six swivel blades that can be detached and used with the Ankeney Sternal Retractor device are included in this package. During cardiothoracic surgeries, the 1⅜-inch by 2-inch blades effectively retract the sternum. These blades, which are made of premium stainless steel, are long-lasting, resistant to corrosion, and completely autoclavable for frequent usage in sterile settings.
