Injection of vinylite and corrosion

Injection of Vinylite and Corrosion

The injection of vinylite and corrosion is a specialized technique used in the field of anatomy and pathology to study the internal structures of biological specimens. This method involves the use of a polymer known as vinylite, which is injected into the vascular or hollow systems of a specimen to preserve and highlight its internal architecture. The process is often used in conjunction with corrosion techniques to remove surrounding tissues, leaving a clear view of the injected structures.

Methodology

The process of injecting vinylite and applying corrosion involves several key steps:

Preparation

Before injection, the specimen must be properly prepared. This involves cleaning and, if necessary, fixing the specimen to preserve its current state. Fixation is often done using formaldehyde or other chemical fixatives to prevent decomposition.

Injection

Once the specimen is prepared, vinylite is injected into the desired system, such as the vascular system or respiratory system. Vinylite is a type of thermoplastic resin that can be colored to enhance visibility. The injection is typically performed using a syringe or pump to ensure even distribution throughout the system.

Corrosion

After the vinylite has set, the specimen undergoes a corrosion process. This involves the use of corrosive chemicals, such as acids, to dissolve the surrounding tissues. The corrosion process is carefully controlled to ensure that only the unwanted tissues are removed, leaving the vinylite-filled structures intact.

Applications

The injection of vinylite and corrosion technique is used in various fields, including:

• Anatomical Studies: To create detailed models of the internal structures of animals and humans for educational purposes.
• Pathological Investigations: To study the effects of diseases on the vascular and other systems.
• Veterinary Medicine: To examine the internal structures of animals, such as the hoof of a horse, as shown in the image.

Advantages and Limitations

Advantages

• Clarity: Provides a clear view of internal structures without the interference of surrounding tissues.
• Durability: The vinylite models are durable and can be preserved for long-term study.
• Educational Value: Offers a tangible way to study complex anatomical systems.

Limitations

• Destructive: The process is destructive to the original specimen, as tissues are removed.
• Chemical Handling: Requires careful handling of corrosive chemicals, which can be hazardous.
• Complexity: The technique requires skill and precision to execute properly.
