Cobb Elevator

Description

Cobb Elevator

The Cobb elevator is a classic spinal instrument, 28 cm long. Spine surgeons use it to strip muscle from the laminae and to expose the spine for fusion.

Long and strong

At 28 cm, the elevator reaches deep into the wound. Meanwhile, the stiff shaft resists bending as it levers muscle away. The blade has a broad, curved edge.

Three widths

Choose 9.5, 13 or 19 mm. In addition, the narrow blade suits the cervical spine and tight areas. By contrast, the 19 mm blade clears the lumbar spine quickly.

Where the Cobb elevator helps

Spine surgeons use it for posterior exposures. It also helps at the iliac crest when harvesting graft. In addition, hip surgeons may use it to lift muscle from the pelvis.

Technique

Begin at the tip of the spinous process. Then sweep laterally along the lamina, keeping the blade on bone. Packing with gauze afterward helps control bleeding.

Choosing a width

Cervical exposures usually call for the 9.5 mm blade. In contrast, thoracic and lumbar work suits 13 or 19 mm. Consequently, many spine sets carry two widths.

Cobb elevator options

• 28 cm overall
• Blade widths: 9.5, 13, 19 mm
• Broad curved edge

Care of a long elevator

Clean the blade and shaft after every case. Then rinse and dry fully. Inspect the edge and straightness regularly.

Buying essentials

In the rare case the Cobb pattern shows a material flaw, you have three years against manufacturing defects. Our Atlanta team examines this elevator with care before shipment.
