Friedman Bone Rongeurs

Rongeurs are strongly constructed instruments with a sharp-edged, scoop-shaped tip, used for gouging out bone. Rongeur is a French word that means rodent or 'gnawer'. A rongeur is used to open a window in bone, often in the skull. It is used in neurosurgery and orthopedic surgery to expose areas for operation or to aid in removal of the brain.

The Micro Friedman Rongeur are our finest bone rongeurs. The jaws are only 1.3MM wide, and are available straight, angled, and curved.
"Double action" provides a second hinge point. This increases the pressure and force applied to the cutting edges of the rongeur through the lever action provided by the second pivot point. An example of a "double action" bone cutter is the 52167-75.
When opening a mouse skull, there is a great need to avoid traumatizing the brain. For this purpose we recommend using the 52167-80 Littauer bone cutting forceps. The small and sharp head will easily cut through the skull without traumatizing the brain.

The best instruments to use for bone cutting are the bone cutting forceps. When cutting into a larger rat's skull, you can use a bulkier instrument such as the 52167-75 Ruskin bone cutting forceps. The double action allows precise control and steadiness, while the relatively thin head will fit between the dura and skull bone.

For smaller or younger rats, we recommend using a more delicate instrument such as the 52161-05 Micro Friedman Rongeur.
