19mm Beveled Blade

The Cobb Osteotome features a 19mm wide working end with a beveled cutting edge designed to engage bone during controlled surgical cutting and shaping.

The 19mm / approximately 3/4-inch blade provides a useful medium-width working surface for procedures where the surgeon requires greater contact than a narrow osteotome while maintaining controlled instrument positioning.

Straight Cobb Pattern

The straight configuration aligns the cutting blade, shank, and handle along a direct working axis.

This design assists the operating professional in maintaining awareness of blade orientation and directing controlled force toward the intended bone surface during osteotomy and bone preparation procedures.

Extended 28cm / 11" Length

At 28cm / 11 inches overall, the Cobb Osteotome offers extended reach compared with shorter general-purpose osteotomes.

Its long working profile can be advantageous during orthopedic procedures where the surgical site requires deeper access while the operator maintains control from the handle.

Knurled Surgical Handle

The cylindrical handle incorporates a cross-knurled gripping surface designed to provide secure hand contact during manipulation.

The textured profile helps maintain instrument control while positioning the blade and during procedures where measured impact from a surgical mallet is required.

Durable Shank Construction

The solid working shank is designed to transmit controlled force from the handle toward the cutting blade.

This robust construction makes the Cobb pattern suitable for orthopedic procedures requiring a strong, stable bone-working instrument.

Common Surgical Applications

The Cobb Straight Osteotome may be selected by trained healthcare professionals for procedures involving controlled cutting, separation, reshaping, or preparation of bone.

Potential professional applications include:

• Orthopedic osteotomy procedures
• Bone cutting and sectioning
• Bone shaping and contouring
• Bone surface preparation
• Controlled removal of bone
• Trauma surgery
• Reconstructive orthopedic surgery
• Spinal and musculoskeletal procedures
• Corrective bone procedures
• Mallet-assisted orthopedic bone work

Instrument size, blade width, surgical approach, and impact technique should always be selected by the operating healthcare professional according to the specific procedure.

Osteotome vs. Bone Chisel

A Cobb Osteotome is a specialized bone-cutting instrument designed for controlled surgical division and reshaping of bone.

Its beveled 19mm working edge allows the instrument to engage bone during osteotomy or bone preparation. The long straight shaft provides reach while the heavy handle and shank support controlled force transmission.

Because “bone chisel” is also commonly used when searching for this type of orthopedic instrument, the Cobb Osteotome may be described as an orthopedic bone chisel or surgical bone-cutting osteotome, depending on the clinical terminology being used.

Use with a Surgical Mallet

When required by the operative technique, the Cobb Osteotome may be used with an appropriate surgical mallet to deliver controlled impact to the instrument.

The surgeon should select the appropriate mallet, impact force, blade width, and instrument position according to the procedure being performed.

Cleaning, Inspection & Instrument Care

Inspect the Cobb Osteotome before each use, paying particular attention to the:

• 19mm cutting edge
• Beveled blade
• Shank
• Handle
• Knurled gripping surface

Do not use the instrument if the blade is visibly damaged, deformed, excessively worn, cracked, or otherwise unsuitable for safe surgical use.

Cleaning, decontamination, sterilization, inspection, and storage should be performed according to the applicable manufacturer's instructions, validated healthcare-facility procedures, and relevant professional requirements.

Sharpening or repair of the cutting edge should only be performed by personnel qualified to service surgical instruments.

Professional Use Notice
