A Doyen rib rasp – infant left is a specialized surgical tool used in pediatric thoracic surgery, particularly in infants, to refine or reshape the ribs on the left side of the body. Its design is similar to other Doyen rib rasps but is specifically scaled down for the delicate bones of infants. The instrument features a narrow, curved blade that allows the surgeon to smooth or reshape the ribs with precision, commonly used during procedures that address congenital chest deformities or other rib-related issues in young children.
