As an important tool in medical education and practice, the shoulder intra - cavity injection model has a variety of unique training functions, which together provide a comprehensive and efficient learning platform for medical staff.

First of all, the model can simulate the real shoulder anatomy, including the shoulder joint cavity, the acromioclavicular joint and other key parts. This highly simulated design allows students to perform puncture injection training in an environment close to actual combat, so as to better master the anatomical characteristics and puncture techniques of different areas of the shoulder.

Secondly, the intracavitary injection model of the shoulder joint supports puncture injection training from multiple different sites. In addition to the conventional puncture of the shoulder joint cavity, the puncture training can also be performed on the bursae acromialis subacromialis, acromioclavicular joint, tendon sheath of the long head of the biceps and suprapular nerve block. This multi-site training method helps students to fully understand the puncture technology in different areas of the shoulder and improve the comprehensive operation ability.

In addition, the model is equipped with an intelligent feedback system, and the control box displays a green light when the puncture is performed correctly. This instant feedback mechanism not only allows students to know the results of operations in real time, but also allows them to quickly correct errors when they occur, thus speeding up the skill acquisition process and improving learning efficiency. This intelligent design enables students to gradually master accurate puncture positioning technology in the process of trial and error and correction.

At the same time, the skin surface of the shoulder cavity injection model can be cleaned with soapy water to facilitate disinfection and cleaning after use. This design not only ensures the hygiene of the model, but also prolongs the service life of the model. Some models are also equipped with replaceable skin components, further enhancing the usefulness and durability of the models.

To sum up, the shoulder joint intracavitary injection model, with its highly simulated anatomical structure, multi-site puncture training function, intelligent feedback system and easy cleaning and maintenance design, provides a comprehensive, efficient and safe learning platform for medical personnel. Through these unique training functions, students can practice repeatedly in an environment close to actual combat, gradually master the puncture technology in different areas of the shoulder, improve the comprehensive operation ability, and lay a solid foundation for future clinical practice.
