Cobb Type Spinal Elevator 4mm, 27cm

Clinical Application

Designed for spine surgeons and OR teams, this Cobb-type spinal elevator is used for controlled subperiosteal dissection and elevation of periosteum and soft tissues from osseous surfaces during posterior and anterior spinal exposures. The 4 mm working tip enables precise tissue separation in confined corridors and between bony elements, facilitating visualization of laminae, facets and transverse processes and aiding preparation of graft beds and implant sites.

Design & Configuration

The Cobb pattern features a tapered, spatulated working tip that provides a broad, atraumatic contact surface for peeling periosteum and elevating soft tissue layers without excessive point pressure. A 27 cm shaft gives reach into deep lumbar and thoracic exposures while maintaining tactile feedback and control at the tip. The rigid shaft geometry transmits manual force efficiently for controlled dissection and blunt separation in tight operative fields.

Instrument Specifications

• Pattern: Cobb-type spinal elevator
• Working tip width: 4 mm (Cobb pattern)
• Overall length: 27 cm
• Primary uses: Subperiosteal dissection, periosteal elevation, soft-tissue mobilization for spinal exposure

Material & Construction

Manufactured from surgical-grade stainless steel to provide corrosion resistance and durability under repeated sterilization cycles. The robust, single-piece construction commonly used for Cobb elevators ensures rigidity and reliable tactile transmission during dissection. The smooth polished finish eases cleaning and reduces tissue adherence.

Quality & Compliance

Manufactured by FDA-registered OEM facilities and produced under strict quality control standards.
