The natural large shoulder joint model is a teaching and training tool made according to the real proportion and anatomical structure of the human body, mainly used to display the morphology, structure and movement characteristics of the shoulder joint. The shoulder joint, as one of the most flexible joints in the human body, is composed of the humerus, scapula and collarbone. It works in conjunction with the surrounding ligaments and muscle groups to complete multi-directional movements of the upper limbs. The model is designed to visually present the anatomical relationship and range of motion of the joint, and can truly simulate the flexion, extension, abduction, rotation and other movements of the shoulder joint, enabling learners to have a more intuitive understanding of its complex structure and function.

This model is of great significance in clinical teaching. It can help medical students and nursing staff systematically master the anatomical knowledge of the shoulder joint, intuitively understand the connection between bony structure and surrounding soft tissues, and especially has a clear demonstration effect on the pathological mechanisms of diseases such as periarthritis of the shoulder, joint dislocation, and rotator cuff injury. Meanwhile, the model can be used for rehabilitation training guidance, helping patients understand the movement patterns of their joints, enhancing their coordination, and improving the rehabilitation effect.

In addition, the natural large shoulder joint model also plays a significant role in clinical research and medical education. Through visualization and actionable presentation, it not only enhances teaching efficiency but also provides reliable references for medical staff in diagnosis, treatment and rehabilitation.
