Description
The V. Mueller NL4253‑91T Kerrison Rongeur is a highly precise spinal surgical instrument designed for ultra-fine removal of bone and ligament during delicate decompression procedures.
This instrument features a long, slender shaft (~9 1/2 inches) and a Kerrison-style footplate with a 1 mm bite size, making it ideal for extremely controlled, minimal bone removal in very confined or sensitive areas, such as near nerve roots and critical structures.
The footplate design allows the instrument to be positioned beneath bone or ligament, while the upper punch mechanism removes material with precision. The pistol-grip, spring-loaded handle provides smooth, one-handed operation and enhanced tactile feedback for delicate work.
The gold-colored components indicate tungsten carbide (TC) inserts, which increase durability and maintain a sharp cutting edge over repeated use. Constructed from surgical-grade stainless steel, the instrument is suitable for repeated sterilization.
