Bionic structure with real human body
1. The outer skin is made of TPE polymer material, and the whole body is represented by flexible simulated skin, subcutaneous and muscular tissues, real feel and elastic touch. The simulated skin must have good flexibility (hardness 5-10shore A, tensile tear strength greater than 700%).
2. The whole body is a complete bionic structure of the whole body; it reflects the true bony signs of each part; the bionic bone must have good toughness (bending fracture strength is greater than 95Mpa).
3. The joints of all parts of the body are connected by metal components to ensure firmness and durability. The model has fractures of upper limb forearm and lower leg calf fracture. To make students understand the abnormal movement, angle deformity, and bone fricative produced after the fracture. 

The upper and lower limbs of the fracture should be fixed with splints in time to prevent vascular nerve damage around the fracture caused by repeated activities.
Second, the function
1. The application of the model training enables students to master the method of fracture reduction and fracture fixation.
2. The lower limb fracture can also be used for bone traction nursing training and skin traction nursing training.
3. The lower limbs can also be used for the care of fracture external fixator.
4. Diagnosis and treatment training for Kleb's fracture can be carried out.
5. Diagnosis and treatment of root fractures can be conducted.
6. Training of tibia and fibula reduction.
7. A variety of fracture forms of bones throughout the body can be customized according to needs
