Fergusson bone holding forceps are categorized by which defining characteristic?

Fergusson bone holding forceps are specifically characterized by the design of their jaws, which include two cusps that form a triangular shape at the end. This design feature is essential because it allows for better stabilization and handling of bone fragments during surgical procedures. The triangular configuration provides an effective grip on bone surfaces and aids in the precise manipulation required in orthopedic surgery. This structural design is what distinguishes Fergusson bone holding forceps from other types of surgical forceps, thus making it the correct defining characteristic. Understanding this design helps veterinary professionals recognize and appropriately utilize these instruments in clinical settings.
