Description

The Kerrison Laminectomy Punch with Bone Ejector – 40° Upward Jaw is a precision spinal instrument designed for controlled bone resection during laminectomy, laminotomy, decompression, and other spinal surgical procedures. The instrument combines the proven cutting performance of a Kerrison punch with an integrated bone ejector mechanism, allowing efficient removal of excised bone fragments and improving procedural workflow.

The instrument features a 40° upward jaw configuration that provides enhanced access and visualization when working within confined operative spaces. This angled jaw design facilitates controlled bone removal while allowing surgeons to maintain optimal instrument positioning during spinal decompression procedures.

The integrated bone ejector mechanism assists in clearing excised bone fragments from the instrument jaws, reducing interruptions during surgery and improving operative efficiency. This feature is particularly beneficial during procedures requiring repeated bone resection and precise decompression.

The Kerrison Laminectomy Punch with Bone Ejector is available in three shaft lengths to accommodate varying surgical approaches and anatomical requirements. The 18 cm (7″) shaft length provides excellent maneuverability for standard spinal procedures, while the 20 cm (8″) and 23 cm (9″) shaft lengths offer increased reach for deeper operative fields and more complex procedures.

Available bite sizes range from 1 mm to 6 mm, allowing surgeons to select the most appropriate cutting profile according to the surgical indication and anatomical requirements. The 1 mm bite size is available only in the standard Kerrison configuration, while the bone ejector mechanism is offered with bite sizes from 2 mm through 6 mm. This comprehensive range of configurations provides exceptional versatility across a wide variety of spinal procedures.

Commonly used during laminectomy, laminotomy, spinal decompression, and neurosurgical procedures, the Kerrison Laminectomy Punch with Bone Ejector delivers the precision, durability, and reliability required in modern spinal surgery. Manufactured from premium surgical-grade stainless steel, every instrument undergoes stringent quality control inspection to ensure durability, corrosion resistance, consistent cutting performance, and dependable long-term operation.
