An amputation saw is a specialized medical instrument. They are designed for the precise and efficient removal of limbs.
These saws have evolved over time. They are employed by skilled surgeons and medical professionals during amputations and disarticulations. It ensures clean and accurate cuts. This is important for the patient’s well-being and post-operative recovery.
Here we’re going to share everything about an amputation saw. We’ll also share some of the best amputation saws for you. So, keep reading this article.
What Is an Amputation Saw?
An amputation saw is a surgical saw specifically designed to cut through bone. Unlike regular saws, amputation saws have a narrow blade and wider set teeth. It helps to prevent the bone from binding as you cut.
The most common types of amputation saws are the gigli saw and osteotome. The gigli saw has a wire saw with handles on each end to manipulate the blade. It takes practice to use but can create a very smooth cut. The osteotome looks more like a regular saw but with a tapered blade to get into tight spaces. It may require a mallet to help drive the teeth through bone.
For a traumatic amputation in the field, a gigli saw or osteotome are good options. They don’t require power and are very portable. For surgical amputations, an electric oscillating saw is often preferred. These saws move the blade in tiny orbits to quickly cut through bone with minimal vibration. They produce an extremely clean cut but require a power source and tend to be more expensive.
No matter the saw, the principles of amputation remain the same. You want to cut through the bone swiftly while sparing as much soft tissue as possible. Multiple cuts may be required for larger bones. The saw should be held at a 90 degree angle and drawn smoothly through the bone using light pressure and short strokes. With practice, an amputation saw can become an invaluable tool for saving lives through necessary amputations.
Benefits of Using an Amputation Saw
An amputation saw is a vital tool for any emergency responder or surgeon. These specialized saws provide several benefits. It makes the difficult procedure of limb amputation safer and more efficient.
Precision and Control
Amputation saws are designed for cutting through bone. They have a narrow kerf, or cut width, that minimizes damage to surrounding tissue. Their blade shape and tooth design also provide enhanced control. It helps you to make precise, accurate cuts. Some models even have guides or guards to help ensure proper cutting depth and angle.
Efficiency
The right saw can reduce the time required to perform an amputation. Models with higher tooth counts can cut through bone much faster than a standard wood saw. Some have a reciprocating or oscillating action that speeds the cutting process. The faster you can complete the procedure, the less blood loss and risk of shock for the patient.
Safety
Amputation saws also have safety features to protect both the patient and the person. They have a guarded blade to avoid unwanted cuts. Some have mechanisms that retract the blade into the handle when not in use. Ergonomic and slip-resistant handles make the saws easier and safer to grip. It also helps to control during a difficult procedure.
Sterility
For surgical amputations, sterility is essential. Autoclavable amputation saws can be sterilized to avoid infection. Some models are also fully disposable to ensure sterility. Either type allows for a much safer surgical environment.
Key Features of Amputation Saws
An amputation saw is a medical device. It helps to cut through bone during surgical procedures. When choosing an amputation saw, there are several key features to consider:
Blade Design
The blade design largely determines how effective and safe the saw will be. Look for a saw with:
- A narrow kerf blade (the width of the cut) which minimizes bone damage. Wider cuts need more healing time and rehabilitation.
- Variable tooth geometry, with larger teeth near the handle for fast cutting and smaller teeth at the tip for precision. This combination provides speed and control.
- A blade guard to protect soft tissue during the procedure. Retractable guards are ideal as they can be moved out of the way when not needed.
- High quality, medical-grade stainless steel or carbide blade material which holds an edge well and can be properly sterilized.
- A blade that cuts on the pull stroke. Push-cut blades can slip, risking injury to the patient or surgical team. Pull-cut blades provide more control and safety.
Ergonomic Handle
An ergonomic handle reduces fatigue and provides maximum control, which is essential during long or complex procedures. Look for a handle with:
- Textured, non-slip grip material.
- A design that keeps the wrist in a neutral position.
- Sufficient length and girth to grasp comfortably, even with gloved hands.
- Finger grips or finger guards to prevent slipping.
Adjustable Features
Adjustable features allow the saw to be customized for different anatomies and procedures. Useful adjustments include:
- Blade depth/extension which controls how deep the blade can cut.
- Blade angle/bevel which can be angled for different cuts.
- A tension adjuster to tighten or loosen the blade. Tighter tension reduces blade wander while cutting.
- An adjustable shoe/guard to stabilize the bone during cutting.
Safety Mechanisms
Multiple safety mechanisms are important for preventing injury. Look for features like:
- A blade locking mechanism to fix the blade in place when not in use.
- Retractable blade guards.
- Emergency blade release in case the blade gets stuck or overheated.
- Thermal overload protection to prevent overheating.
- A water attachment for cooled cutting and improved visibility.
How to Properly Use and Maintain an Amputation Saw
To properly use and maintain your amputation saw, following some key steps will help keep it in good working order and ensure safe operation.
Select the Right Blade
Choose a blade specifically designed for cutting bone. A bone saw blade will have smaller teeth that are set close together. This allows it to cut through bone efficiently without binding. The blade should also be made of hardened steel and coated to resist corrosion. For most amputations, a blade with 32 to 36 teeth per inch is a good all-purpose choice.
Tighten the Blade Securely
Before using your amputation saw, tighten the blade securely in the frame. If the blade is loose, it can bend, bind, or break during use and cause injury. Tighten the blade until it’s held firmly in place but can still move smoothly when the saw is operated. Test that the blade is secure by gently tugging on it.
Use a Firm Grip and Steady Pressure
Hold the saw handle firmly and apply steady pressure as you cut. Do not jerk the saw back and forth. Work slowly and carefully, especially when starting a cut. Apply firm and even pressure, allowing the teeth of the blade to do the work. Increase pressure slightly as you cut deeper through the bone.
Cut on the Pull Stroke
Amputation saws cut most efficiently on the pull stroke. Gently push the saw forward, then pull back using more pressure to advance the cut. Continue alternating push and pull strokes until you cut through the full diameter of the bone.
Lubricate and Clean the Saw
After use, thoroughly clean your amputation saw to remove any bone fragments and bodily fluids. Then lubricate the blade with oil to prevent corrosion before storing.
Wipe excess oil from the blade and frame. For storage, loosen the blade tension slightly but do not fully detach the blade. Keep the saw in a dry place.
With proper use and care, an amputation saw can provide safe and effective performance. However, as with any medical equipment, take caution and handle these saws responsibly to avoid injury. If at any time your saw shows signs of damage or wear, replace it immediately.
Amputation Saw Safety Tips and Precautions
Operating an amputation saw requires focus and care to avoid injury. Follow these safety tips to keep yourself and others safe during use.
Wear protective gear
Always wear protective gloves, eyewear, and protective clothing when operating an amputation saw. Saw blades can kick up debris and the teeth are extremely sharp. Gloves will protect your hands, eyewear will shield your eyes, and long sleeves and pants will prevent cuts to your arms and legs.
Maintain a firm grip
Hold the saw handle firmly and securely with both hands during operation. An amputation saw can jerk or kick as it cuts through bone, and you need a solid grip to control the blade. Keep your hands away from the blade at all times.
Apply firm with even pressure
Apply firm and even pressure as you cut to avoid blade binding or kickback. Do not force the saw or apply uneven pressure, which can cause the blade to bend or break. Move the saw slowly and deliberately using smooth, controlled motions.
Cut on a stable surface
Only operate an amputation saw on a stable surface. An unstable surface like dirt or gravel can cause the material to shift during cutting and lead to loss of control or injury. A sturdy table, saw horse, or bench is ideal. Secure the material in place with clamps if possible.
Disconnect power when changing blades
Always disconnect the amputation saw from its power source when changing blades. The blade teeth remain extremely sharp even after use and can cause severe lacerations. Wear heavy-duty protective gloves when handling saw blades.
Allow blades and motor to cool before handling
The saw blade, blade guard, and motor can remain hot for some time after use. Allow all parts to cool completely before handling or servicing to prevent burns.
Perform regular maintenance
Conduct regular inspections and maintenance on your amputation saw to ensure safe operation. Sharpen or replace dull blades, check that all parts are secure, and lubricate moving parts as directed in the owner’s manual. Never operate a saw that is damaged or malfunctioning.

How to Choose the Right Amputation Saw
Choosing the right amputation saw for your needs is important. The saw you select can significantly impact the precision and efficiency of your Here are some steps to help guide you in finding an amputation saw that’s perfectly suited for the job.
Determine the type of cuts needed
Consider what types of cuts you need to make-do you need to cut through bone, soft tissue, or both? Powered amputation saws that can handle cutting through bone and hard materials include oscillating saws, rotary tools, and sagittal saws. For softer cuts, options like scalpels, knives, and manual saws may work well. Think about the specific procedures you’ll be performing to determine the best tool for the job.
Choose between manual or powered
Manual saws require physical effort to operate but can provide more control and precision. Powered saws, like oscillating saws and rotary tools, use electric motors to power the blade, reducing effort but potentially decreasing control. Consider your needs for precision versus efficiency. For most amputations, powered saws are typically preferred.
Select the proper blade
The blade determines what the saw can cut through. Blades come in a range of widths, lengths, and grits. Wider blades cut faster but may lack precision. Longer blades can cut deeper. Blade grit refers to the sharpness-higher grit blades cut cleaner but dull faster. Choose a blade width and length suitable for the bone and tissue being cut. For precision, select a higher grit. Multiple blades may be needed for different parts of the procedure.
Consider additional features
Extra features to consider include: adjustable speeds for more control, ergonomic handles for comfort, dust extraction ports to reduce contaminants, and sterilization compatibility for reuse. Think about what additional capabilities would improve safety, efficiency, and ease of use for your particular needs.
Test the saw
If possible, test the saw before purchasing to ensure it meets your needs. See how it handles, check that it can make the necessary cuts, and ensure the blade lasts sufficiently long. Testing the saw yourself provides the most accurate assessment to find the right amputation saw for the job.
Following these guidelines will help you select an amputation saw that provides the precision, power, and features you need for safe and effective surgical procedures. The right saw for the task can make a big difference in outcome.
