Rongeurs are like pliers with a heavy, pointed jaw. With their heavy contrsuction, rongeurs are used for gnawing holes in bones during surgery. The scoop shaped tip of the rongeur is used for gouging the bone. This could be neurosurgery where the surgeon must remove part of the skull to expose the brain. Ronguers maybe used in an orthopedic surgery or even a cadaver dissection.
Along with the rongeurs, we carry bone cutters, too. Bone cutters are also heavy duty, manual instruments designed for manipulating bones during small animal surgery. They are shaped like scissors or pliers. Using the sharp edge, bone cutters can penetrate bones or even bisect them. Bone cutters are frequently used in orthopedic surgery or oral surgery.
