jaws 4.0 mm wide, bayonet shaped, curved, 7-1/2" (19.0 cm)Jansen Rongeur is an instrument designed for use in bone reshaping and handling. Procedures such as fracture repair or procedures such as craniotomies that require access through the bony skull are ideal situations for use of this instrument. This rongeur can be used to enlarge preformed holes in bone to increase access to the surgical field or to cut or gnaw away at smaller bone or other types of hard tissue layers. This instrument uniquely features a slight curvature as well as a bayonet shape that allows it to access some more difficult to reach areas.
