Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of medical teaching aids, and particularly relates to a human medical teaching aid for scoliosis. BACKGROUND

[0002] Medical teaching aids are various tools and devices used for medical education and training, including anatomical models, manikins, and the like. These aids help students and medical professionals learn about human anatomy, skill operations, and theoretical knowledge, and improve their clinical abilities through practice and simulation. Scoliosis is a spinal deformity characterized by a sideways curvature of the spine, often forming a "C" or "S" shape. In severe cases, physical therapy, braces, or surgery may be required. Understanding the early signs of scoliosis and receiving regular checkups are crucial for prevention and management. There are few applications for scoliosis teaching aids on the market.

[0003] A splicable spinal model is disclosed in Chinese Patent No. 202021723050.X, which includes a vertebra model and a spinal cord model. Each vertebra in the vertebra model has a magnet inside, located below the articulating surface of the vertebra. Each vertebra can be detachably joined to each other at the articulating surface by the magnetic attraction of the magnet according to the physiological curvature of the human spine, to form a vertebra model with the required curvature. The spinal cord model is placed in the spinal canal formed by the articulation of each vertebra. The spinal cord model is flexible to adapt to the different curvatures of the vertebra model. The vertebra model and the spinal cord model of the utility model cooperate with each other, and the vertebrae are detachably connected by magnetic force. The different physiological curvatures of the human spine can be simulated by disassembling and reassembling at different angles. The flexible spinal cord model can well match the curvature of the vertebra model.

[0004] Existing spinal teaching aids can only simulate the condition of the spine, but cannot understand the changes in the human body contour according to the changes in the spine, cannot express the changing relationship between the human body and the skeleton, and thus lead to poor learning effect and insufficient clinical application. At the same time, the shape of scoliosis cannot be flexibly and quickly adjusted, and the scoliosis condition and the change of the human body in different postures such as standing, bending, sitting, and lying cannot be quickly simulated, thereby affecting subsequent clinical judgment and treatment.
