The principle of the natural large elbow joint model

The principle of the natural large elbow joint model mainly lies in reproducing the anatomical form and movement laws of the human elbow joint through simulation structures, enabling learners to intuitively understand the structure and function of the joint. The elbow joint is a composite joint composed of the humerus, ulna and radius, supported by the joint capsule, ligaments and muscles. Its main forms of movement include flexion, extension and rotation. When designing the model, the bony structure and joint connection relationship were restored in accordance with the standard anatomical scale, and at the same time, the natural movement trajectory of the joint was simulated through the movable device.

This model mostly adopts strong and lightweight materials, such as high-molecular plastics or synthetic resins. Its surface structure is clear and can accurately display the articular surface, articular processes and ligament attachment points. Some high-end versions are also equipped with transparent components or detachable designs, allowing learners to observe the internal operation mechanism of the joint and helping to better understand the changes of the elbow joint under movement and force.

In teaching applications, the natural large elbow joint model can not only help students master the anatomical characteristics of the elbow joint, but also be used for clinical training, such as the diagnosis and treatment practice of fractures, dislocations and joint lesions. At the same time, it also plays a significant role in rehabilitation and sports medicine, being able to visually demonstrate the mechanism of movement limitation after elbow joint injury and provide a reference for rehabilitation treatment.

Therefore, the natural greater elbow joint model, with its scientific simulation principle, provides an intuitive and reliable learning tool for medical teaching, clinical training and rehabilitation research.
