Kerrison Rongeur (also known as a Kerrison Laminectomy Punch or Kerrison Bone Punch). It is a premier instrument primarily used in spinal surgeries, neurosurgery.

It is engineered to perform highly controlled, precise removal (nibbling away) of thin bone layers, posterior spinal margins, ligamentum flavum, or lamina. This allows the surgeon to perform a laminectomy or foraminal decompression to safely relieve pressure on pinched spinal nerves or the spinal cord.
