Intra-articular injection model of the shoulder joint

The intra-articular injection model of the shoulder joint is a professional simulation tool used in clinical teaching and skills training. It highly restores the anatomical structure of the human shoulder joint, especially the distribution characteristics of the joint cavity, bony landmarks and surrounding soft tissues. In practical operations, medical learners often encounter problems such as inaccurate positioning of injection in the shoulder joint cavity, improper puncture angles, or leakage of drug liquid. The application of this model precisely provides a safe and intuitive platform for solving these problems.

The model is usually made of simulated silicone and polymer materials, with a touch close to human tissue, allowing the operator to accurately select the needle insertion point by touching bony landmarks such as the coracoid process and acromion. Meanwhile, the model is equipped with a simulated joint cavity structure inside. During injection, it can clearly feedback the tactile sensation and resistance changes when the needle tip enters the joint cavity. If the operation is correct, a simulated effect of smooth injection of the liquid medicine can also be observed. This not only helps learners master the depth and Angle of puncture, but also cultivates their intuitive judgment of the success or failure of injection.

In addition, the intra-articular injection model of the shoulder joint supports repeated operations, which can effectively improve the clinical skills of medical students, resident physicians and primary care physicians, and reduce the risks caused by improper operations. It is widely applied in teaching hospitals, skill centers and continuing education training, which not only ensures the authenticity of learning but also avoids direct harm to patients. It can be said that the emergence of this model has provided a scientific, systematic and repeatable training approach for the diagnosis, treatment and training of shoulder joint diseases, which is of great significance for improving medical safety and teaching quality.
