The Revolutionary Significance of Plastination in Veterinary Education

In the field of veterinary education, plastination is reshaping teaching paradigms with its unique advantages. This bioplasticization technology, pioneered by German scientist Gunther von Hagens in 1978, replaces water within tissue cells with reactive polymers through a vacuum impregnation process, allowing specimens to maintain their natural form for extended periods without the need for formalin preservation. This technological breakthrough has brought about multiple changes in veterinary education.

Traditional immersion specimens release formaldehyde, which not only harms the health of teachers and students but also limits the diversity of teaching settings. Plastination completely eliminates chemical irritants, making teaching possible in laboratories, classrooms, and even the field. Its dry and portable nature is particularly suitable for educational institutions with limited resources, providing a new solution for veterinary education in remote areas.

Compared to two-dimensional atlases or virtual models, animal plastinated specimens can display anatomical structures in multiple dimensions. Examples include the three-dimensional relationships of organs in large animals such as cattle and horses, the distribution patterns of blood vessels and nerves (such as the nerve plexuses in canines), and the juxtaposition of healthy and diseased tissues. This "touchable anatomy" significantly enhances students' spatial awareness of complex structures, particularly in understanding challenging concepts such as the four-compartment structure of ruminants.

Plastinated animal specimens support tiered instruction, allowing for the identification of important anatomical landmarks (such as the scapula in horses) and the simulation of surgical procedures, such as practicing rumen incision design on sheep plastinated specimens. The ability to repeatedly manipulate plastinated specimens greatly reduces psychological stress for beginners.

A single animal plastinated specimen can last for over 20 years, with maintenance costs only one-fifth that of traditional specimens. This characteristic is particularly important in the context of the global expansion of veterinary education.

With the integration of technologies such as 3D scanning, plastinated animal specimens are forming a hybrid "physical-digital" teaching system. They are not only knowledge carriers but also crucial mediums for cultivating future veterinarians' "hand-eye-brain" coordination skills. As veterinary medical education transitions from empirical science to precision science, the value of plastinated animal specimens will continue to be highlighted.
