Amputation Knife

Quick Answer: An amputation knife is a long, straight surgical knife with a fixed blade, made to divide skin and muscle around a limb during amputation. In colleges it is taught in instrument identification and can be used to cut large specimens in anatomy and pathology rooms.

A Knife From the Era Before Power Tools

Amputation knives descend from the long blades used when limb amputation had to be fast, before anaesthesia. A long blade could be swept around the limb in one or two strokes to divide the soft tissues down to the bone, after which a saw completed the operation. Patterns such as the Liston knife have a single edge; the Catlin pattern is double-edged and sharp-pointed, made to pass between paired bones such as the radius and ulna.

In modern practice the skin is usually opened with a scalpel and vessels are tied or sealed, while a long knife remains convenient for dividing large muscle groups cleanly. The instrument keeps its place in surgical teaching, where students identify it, name its parts and explain why it is long and heavy. It is also useful in the post-mortem room and for slicing large preserved specimens in one stroke.

The listing does not give the blade length, edge pattern or handle material. If your syllabus names a specific pattern, state it when ordering.

Specifications

Applications

• Instrument identification in surgery, orthopaedics and OT technician courses
• Dividing large muscle masses in cadaveric teaching of amputation
• Cutting large preserved organs and specimens in pathology museums and anatomy departments
• Displays on the history of surgery

Care & Handling

• Carry and pass the amputation knife handle-first with the edge turned away, and never leave it hidden in a tray of water.
• Clean it with detergent and a brush straight after use and dry it completely; if the blade is carbon steel, a light film of oil prevents rust.
• Keep the edge honed on a fine stone and protect it with a blade guard or a slotted rack in storage.

Frequently Asked Questions

How is an amputation knife different from a scalpel?

A scalpel has a short, usually replaceable blade for precise incisions. An amputation knife has a much longer fixed blade designed to cut through a large mass of soft tissue in a single sweep.

What is the difference between a Liston knife and a Catlin knife?

The Liston knife has a long, single-edged blade. The Catlin knife is double-edged with a sharp point, designed to pass between the two bones of the forearm or leg.

Is the amputation knife still used in surgery?

Less than in the past, because skin is now often cut with a scalpel and bleeding is controlled with ligatures and electrosurgery, but a long knife is still convenient for dividing large muscle groups.

Why do anatomy and pathology departments use a long knife?

A long blade cuts a large organ or preserved specimen in one smooth stroke, leaving a flat, even face that shows internal structure better than several short cuts.

How should the knife be sharpened?

Hone it on a fine oilstone or ceramic stone at a consistent shallow angle, then strop it. Badly damaged edges should be reground by an instrument sharpening service.

How should the knife be stored?

In a slotted rack, an instrument roll or with a blade guard, so the edge does not touch other instruments and nobody can grasp the blade when reaching into a drawer.
