Kerrison Bone Punch Up-Bite 4.0 mm Bite 22.5 cm (8.9)

Controlled Access for Deliberate Rongeur Work

The Kerrison Rongeur 9" 225mm 4mm 40° up is a surgical rongeur intended for controlled biting and removal of small amounts of hard tissue during operative work. Its 40° upward bite direction helps position the working end when access or line of sight is limited, while the 225mm working length supports reach within deeper operative fields. The 4mm bite size provides a defined working dimension for instrument selection. Suitable for workflows in General Surgery and Neurosurgery, this rongeur combines directional control, extended reach, and a familiar rongeur format for tasks requiring deliberate, well-positioned bites.

Use Cases

• General Surgery workflows requiring controlled nibbling or removal of small amounts of hard tissue.
• Neurosurgery workflows where an upward-facing bite direction can support positioning within the operative field.
• Work in deeper or less accessible fields where the 225mm working length provides useful reach.
• Procedures requiring selection of a defined 4mm bite size for consistent instrument positioning.
• Operative tasks where a 40° up configuration helps align the working end with the intended bite path.

Specifications

Care & Handling

• Inspect the bite area, alignment, and operating mechanism before and after use for visible damage or impaired movement.
• Handle the rongeur carefully to protect the bite edges and 40° up configuration from impact or distortion.
• Store the cleaned and inspected instrument in a manner that protects the working end from contact damage.
