Focused Access for Controlled Bone Removal

The 9" Kerrison Rongeur 4mm Pin Ejector is a surgical rongeur intended for controlled removal of bone during operative work. Its 4mm bite size supports focused engagement, while the 9" overall length provides useful reach where access and hand positioning matter.

Suitable for general surgery and neurosurgery settings, this rongeur provides a purpose-built option for biting tasks without adding unnecessary complexity to the instrument setup. Its familiar rongeur format supports straightforward selection, use, inspection, and care within established facility protocols.
