Scalpels autopsy knife

Types of Scalpels

An autopsy knife is a type of surgical scalpel that has specific features for performing autopsies. It usually consists of a long, broad blade made from steel to keep the edge sharp for extended periods of use. Its handle is typically made from tough synthetic materials and might have ribbing or grooves to ensure a solid grip when handling it, even with wet hands or used in precise body cuts.

The main types of scalpels autopsy knife found on the market include:

• Disposable scalpels: Autopsy activities are performed daily, and that's why most pathologists prefer going for disposable autopsy scalpels. These are usually light in weight and designed from plastic or stainless steel. Since these instruments are thrown away, the risk of the patient re-infection is wiped out completely.
• Ball-tip forceps: Ball-tip forceps are used to handle delicate organs or tissues and have small balls at the end of the blades for a gentle but firm grasp. During an autopsy, they are used in the removal or examination of organs and tissues without damaging them.
• Belly scalpels: Belly scalpels are a variety of surgical knives that have wide and deep blades to easily go through tough abdominal tissues. They are mainly used in autopsies when opening up a body for examination purposes.
• Scalpel handles the number 3 and number 4: Scalpels handle the number 3 and number 4 are classic handles made for fine, detailed work. However, it is the number 3 handle that is frequently used together with smaller blades, and the number 4 handle is usually associated with larger blades.
• Double bitted scissors: Double bitted scissors have two opposing blades with scissor-like openings for cutting tissues during dissection in an autopsy. They can cut through thick and thin tissues due to their two-edged design.
• Back bended forceps: Back bended forceps are tissue graspers that have slender jaws with ridged inner surfaces for firmly holding tissues during dissections. Their design allows easy manipulation in tight body cavities.

Industrial Applications

• Precision cutting in autopsies: Scalpel knives are primarily used for making incisions with utmost precision during autopsy procedures, allowing forensic pathologists to dissect tissues without damage. Their sharp blades enable detailed examinations.
• Tissue dissection: The main function of autopsy scalpels is to cut through and separate different body tissues. This is crucial because it allows organs to be examined for evident signs of disease or trauma.
• Historical preservation: In some cases, anatomical specimens are treated and kept for future historical studies. Autopsy knives allow careful anatomical studies of tissues that can be preserved in formaldehyde or any other preservatives used in anatomical application.
• Research and development: Autopsy scalpels are used in laboratories to carry out research related to diseases or bodily functions to develop medical treatments and procedures. Autopsy scalpels provide more precise cuts than regular surgery knifes and can therefore be used to study the disease's effect on the body in depth.
• Education: Autopsy scalpels are useful in crime scene investigation courses and medical school dissections. Students gain practical experience using an autopsy scalpel to understand anatomy and pathological changes in cadavers related to diseases or injuries. This contributes to the formation of future doctors and pathologists.

Product Specifications and Features

Key features

• Blade composition: Autopsy scalpels are fitted with stainless steel blades that are resistant to rust and corrosion. Only surgical stainless steel and carbon steel are used to make the sharp and durable blades. These materials allow the blade to stay sharp for long and give it the ability to resist wear when cutting through even the toughest tissues.
• Blade size: Most autopsy scalpels are about 10 mm in length and come in different widths, preferably from 0.5 to 4 mm, depending on the autopsy knife; wider blades are appropriate for making straight cuts and incisions at a quicker pace, while narrower ones allow more detail work.
• Handle design: The handles of autopsy scalpels are usually made of plastic or metal and shaped to give investigators the right grip when performing autopsies. They are also lightweight so that one doesn't get tired even after several hours of use.
• Safety feature: Scalpel blades are designed with plastic sheathes that can be locked over the edge to ensure safe storage and handling.
• Sterilization: Because most of the scalpels used in autopsy work are disposable, they are manufactured in such a way that they allow the user to sterilize them easily before using them in a forensic examination. This reduces the risk of cross-contamination between different corpses and increases safety standards in practice.

How to install

• Turn off power and unplug: Before doing anything, one should turn off the power to the area where the scalpel will be used and make sure to unplug the scalpel to avoid any accidental.
• Select a scalpel blade: Choose the desired blade size and shape based on the cutting task. The sharper the blade is, the easier it is to cut due to less resistance being felt.
• Attach the blade to the handle: Carefully secure the blade into the slot of the scalpel handle. Press the release button on the handle, insert the blade into the holder, and then release the button to clamp down on the base of the blade firmly.

How to use

• Making an incision: Position the blade parallel to the skin or tissue surface and apply gentle, controlled pressure to begin the incision.
• Applying tension: To ensure a clean cut during a surgical procedure, one should pull the tissue to create some tension.
• Controlled pressure: It's important to use controlled pressure when making incisions. Too much force can tear tissue, while insufficient pressure can slow the cut and lead to uneven incisions.

Maintenance and repair

• Sharpening the blade: Autopsy scalpels require that the blade be brought to the proper angle, usually 15 to 20 degrees, and that there is even force applied. The sharper the blade is kept, the easier and better quality autopsy incisions are done.
• Cleaning: It's important to clean the scalpel immediately after using it. For non-disposable types, clean with a brush and appropriate disinfectant. Autopsy knives should only be cleaned with sharp knife protectors or blades guards and users should be advised to never use their hands to clean a knife regardless of whether the knife is blunt or sharp to avoid injuries.
• Storage: Non-disposable scalpels should be kept in a clean, dry area, preferably in a locked drawer or container to avoid contamination. Disposable scalpels should be stored in a container so that their cleanliness can be maintained.
• Inspection: Autopsy scalpels should be examined regularly for defects or excessive wear. Any damaged parts should be fixed or replaced as necessary to ensure optimal functioning conditions when performing autopsies on suspects.

Quality and Safety Considerations

• Sterilization and hygiene: An autopsy scalpel should be made from materials that are easy to sterilize, such as stainless steel. This helps prevent infection during autopsy procedures.
• Blade sharpness: The blade of the surgical autopsy scalpel should be very sharp so that it can make clean cuts to avoid tearing tissues. A dull blade will necessitate more force to be used which can lead to accidents or injuries.
• Ergonomic design: Handles should be ergonomically shaped to give a comfortable grip and reduce strain on the hands. This is important because pathologists frequently perform intricate tasks for extended periods without autopsy tools.
• Proper disposal: If the scalpel is disposable, it should be properly disposed of in designated sharps containers to prevent needle-stick injuries to self or others who come in contact with the disposed items later.
• Follow regulations: There are standards and guidelines set by the health authority in the forensic industry concerning the use of scalpel. These rules and standards should be followed to make sure the result produced is accurate and legit.
• Regular maintenance: Non-disposable scalpels should be regularly inspected for damage and sharpened as needed to ensure safe usage. Autopsy kits often come with a quick scalpel sharpener that pathologists can use to sharpen dull knives.
• Bleeding control: Since autopsy plays around with body tissues, sometimes blood vessels can get cut and this can lead to massive bleeding. It's important to apply pressure and use hemostatic agents on bleeding areas until any cut blood vessel contracts or gets closed.
