Cobb Periosteal Elevator, Spinal Raspatory, 29 cm / 11 1/2 inch, available in 10 mm, 13 mm, and 19 mm widths.
The Cobb Spinal Rasp (11-976-29) is a 29cm instrument built specifically for spinal procedures, offering three width options, 10mm, 13mm, and 19mm, to match the specific scope of soft tissue and periosteal work required. Among the bone surgery instruments used in spinal surgery, the Cobb pattern is recognized for its long reach and dependable rasping action along vertebral surfaces.
That 29cm length is a deliberate design choice, giving surgeons the extended reach needed to work along the spine without crowding the surgical field or requiring awkward hand positioning during longer procedures. Having three blade widths under one pattern name lets practitioners match the instrument precisely to the vertebral level and tissue volume involved.
Why width selection matters in spinal rasping work:
Narrower 10mm blades suit more contained, precise separation tasks
Wider 19mm blades cover broader tissue segments efficiently
13mm offers a practical middle ground for varied spinal levels
Consistent Cobb jaw geometry across all three widths
Built from surgical-grade stainless steel, this raspatory withstands the mechanical demands of repeated periosteal separation work and standard sterilization protocols, holding its edge precision reliably over years of demanding spinal surgery use.
