Description
The V. Mueller NL4253‑94T Kerrison Rongeur is a precision spinal surgical instrument designed for controlled removal of bone and ligament during decompression procedures.
This instrument features a long, slender shaft (~9 1/2 in) terminating in a footplate-style biting jaw with a 4 mm bite size, allowing efficient removal of bone while maintaining control and visibility in deep surgical fields.
The Kerrison-style footplate slides beneath bone or ligament, while the upper cutting mechanism delivers a precise “punch” action. The pistol-grip, spring-loaded handle supports smooth, one-handed operation and fine control.
The gold-colored components indicate tungsten carbide (TC) inserts, which enhance cutting performance and longevity. Its extended length and narrow profile make it ideal for spinal decompression, laminectomy, and other orthopedic procedures requiring deep access.
Constructed from surgical-grade stainless steel, the instrument is durable and suitable for repeated sterilization.
