The Development Of Anatomical Model

Anatomical models, as core tools in medical education, have seen their classification system evolve with technological advancements. From physical models to digital intelligent systems, various models continue to achieve breakthroughs in structural reproduction and functional simulation, supporting medical education at different stages.

 

 

Based on material and craftsmanship, they can be categorized into wax models, polymer models, and biosimulation models.

 

Wax models: The 18th-century Italian wax anatomical Venus, crafted using a mixture of beeswax and resin, features a removable uterus, the first systematic representation of the female reproductive system. The collection, now housed at the La Specola Museum in Florence, still displays astonishing levels of detail.

 

Polymer models: Modern mainstream teaching models utilize medical-grade PVC or silicone. Examples include the silicone simulation models from Meiwo Science and the ultra-strong human models produced by 3B Scientific. Their layered design showcases the skeleton, muscles, and vascular networks, allowing for repeated disassembly and reassembly.

 

Biosimulation models: Utilizing decellularized matrices or hydrogels, they mimic the characteristics of living tissue. For example, resin-infused vascular casts can realistically reproduce the angles of vascular branches, providing a realistic platform for microsurgery training.

 

Based on function and structure, models can be divided into systemic anatomical models and dynamic functional models.

 

Motor system models include skeletal models (such as models of the physiological curvature of the spine) and muscle models (such as models of the nerve pathways of the head and neck muscles), focusing on demonstrating mechanical distribution and movement mechanisms.

 

Visceral system models: A heart cross-section model made of transparent resin demonstrates valve opening and closing, while a digestive system model recreates the four-layer structure of the stomach wall (from the mucosa to the serosa).

 

Dynamic functional models integrate mechanical transmission systems, such as respiratory devices that simulate diaphragmatic movement or teaching equipment that recreates the synovial fluid cushioning mechanism through magnetorheological fluid technology.

 

Based on the degree of technological integration, models can be divided into digital interactive models and intelligent fusion models.

 

Virtual reality systems: The AnatomyX platform, built based on DICOM medical imaging data, supports nerve bundle tracking and 3D lesion measurement, and its force feedback gloves simulate tissue cutting resistance.

 

Augmented reality solutions: The Sectra holographic table enables real-time dynamic sectioning of organ systems, allowing educators to freely adjust tissue transparency and viewing angles. Smart Fusion Model: A plastic bone model embedded with an RFID tag triggers an AR interface upon scanning, displaying real-time bone density data and fracture risk prediction.

 

Meiwo Science, a comprehensive technology company serving medical schools, primarily provides highly realistic soft silicone anatomical models, 3d The digital anatomy software, and plastination models for medical education.
