OR Grade Kerrison Rongeur 5mm 90° 7″ Down Bite, Surgical Spine Instruments

The OR Grade Kerrison Rongeur 5mm 90° 7″ Down Bite is a specialized surgical spine instrument designed for controlled removal of bone during spinal decompression and other neurosurgical procedures. Its Kerrison-style design provides a narrow working profile that allows the surgeon to access targeted areas around the spinal structures while maintaining controlled manipulation. Featuring a 5mm bite size , this rongeur is intended for removing appropriately sized portions of bone during procedures where precise decompression is required. The 90° down-biting configuration positions the working jaws to facilitate access to bone from a downward cutting direction, making it useful in areas where direct access with a straight instrument may be limited. The 7-inch overall length provides useful reach while allowing the instrument to be controlled within the operative field. This combination of length, angled working end, and defined bite size makes the instrument suitable for professional spinal surgery and neurosurgical instrument trays. Kerrison rongeurs are commonly used during procedures involving laminectomy, laminotomy, spinal decompression, and removal of small portions of bone . Depending on the surgical technique and anatomy, the instrument may assist in removing portions of the lamina or other suitable bony structures to create or enlarge access and decompression areas. The down-biting jaw should be operated with controlled force appropriate to the material being removed. The instrument should not be used as a general-purpose bone cutter or subjected to excessive lateral loading, as improper use can damage the cutting mechanism or affect jaw alignment. Selection of the correct bite size and angle should be based on the surgical procedure and surgeon preference. The OR Grade designation indicates an instrument intended for professional operating-room use. It can be incorporated into spinal surgery sets, neurosurgical instrument trays, and orthopedic spine systems where a 5mm, 90° down-biting Kerrison rongeur is required. For reusable instruments, proper reprocessing is essential. Following the procedure, the rongeur should be cleaned promptly according to established instrument-processing protocols. Special attention should be given to the jaws, hinge, biting mechanism, and internal surfaces where biological material may collect. Before sterilization and reuse, inspect the cutting edges, jaw alignment, spring/action, and overall condition. The OR Grade Kerrison Rongeur 5mm 90° 7″ Down Bite combines a defined 5mm bite, 90° working angle, and practical 7-inch length for controlled bone removal in professional spinal and neurosurgical procedures.
