Bone Cutters & Rongeurs

Bone Cutters and Rongeurs for Sale - Kerrison, Zaufal-Jansen, Semb and More for Orthopaedic, Spinal and ENT Surgery

Bone work in surgery demands instruments that match the specific anatomical site, bone density, and access geometry of the procedure. A Kerrison punch used for laminectomy in the lumbar spine is a fundamentally different instrument from a Zaufal-Jansen rongeur used in mastoid surgery - both remove bone, but the footplate profile, cup size, jaw angulation, and force mechanism reflect entirely different operative requirements. Using the wrong bone instrument in a tight anatomical corridor creates either inadequate bone removal that forces repeated passes, or uncontrolled bone fragmentation that endangers adjacent structures.

This category at NJ Medical Instruments covers the principal bone-removing and bone-holding instruments used across spinal surgery, neurosurgery, ENT, thoracic surgery, and general orthopaedic procedures. All instruments are manufactured from surgical-grade stainless steel at the company's Sialkot facility, CE-certified, and autoclavable.

Spinal and Neurosurgical Bone Instruments

Kerrison Laminectomy Punch

The Kerrison punch is one of the most recognisable instruments in spinal and neurosurgery - its footplate slides under the lamina or ligamentum flavum while the cup above removes a controlled bite of bone or ligament with each closure. The footplate angle (typically 40° or 90° for different levels and approaches), the cup size (2, 3, 4, or 5 mm), and the jaw strength together determine which anatomical level and bone density the instrument handles appropriately.

In lumbar laminectomy and laminotomy for disc herniation, the Kerrison removes laminar bone to decompress the nerve root without the unpredictable fracture propagation that bone cutters would produce at this anatomically critical site. In cervical spine surgery, smaller cup sizes and angled configurations navigate the tighter access corridor. The same instrument appears in skull base surgery for removing petrous bone during acoustic neuroma or petroclival approaches.

The Kerrison Laminectomy Punch available here is CE-certified, surgical stainless, autoclavable.

ENT and Mastoid Surgery Rongeurs

Zaufal-Jansen Bone Rongeur

The Zaufal-Jansen pattern is the combined-name descendant of two otological instrument traditions, and it remains the standard rongeur for mastoid surgery and temporal bone work. The jaw configuration - narrower and more angled than a general bone rongeur - suits the confined mastoid cavity where the surgeon removes dense temporal bone in small controlled bites to expose the mastoid antrum, semicircular canals, and middle cranial fossa plate.

The Zaufal-Jansen Bone Rongeur is the appropriate instrument for ENT units performing mastoidectomy, tympanomastoid surgery, and temporal bone dissection. CE-certified, surgical stainless, autoclavable.

General Bone Rongeurs and Cutting Forceps

Bone Rongeur

The Bone Rongeur in this category is a general-purpose cutting rongeur suited for bone removal across orthopaedic, trauma, and general surgical procedures where the anatomical access and bone density fall outside the specialised instrument requirements of spinal or ENT surgery. It handles bone end preparation, osteophyte removal, and rough bone shaping in wider operative fields. CE-certified, autoclavable.

Bone Cutting Forceps - Angled

The Bone Cutting Forceps Angled delivers cutting force through an angled jaw that reaches bone surfaces not accessible to straight-jawed instruments. Angled bone cutting forceps appear in orthopaedic procedures where the approach angle to the bone surface is oblique - hip surgery, shoulder procedures, and situations where the surgeon's hand position relative to the operative field makes a straight instrument geometrically impractical. CE-certified, autoclavable.

Bone Holding Instruments

Semb Bone Holding Forceps

Gunnar Semb was a Norwegian thoracic surgeon whose bone-holding forceps became the standard in thoracic procedures where rib or chest wall bone needs to be stabilised during resection, plating, or reconstruction. The Semb design grips cortical bone securely through a serrated jaw that distributes holding force to prevent slippage under the traction needed during rib resection or sternal work.

The Semb Bone Holding Forceps is the appropriate instrument for thoracic surgery units, cardiac surgery departments, and trauma teams performing chest wall stabilisation. CE-certified, surgical stainless, autoclavable.
