The significance of the thoracic puncture and drainage model lies in providing medical students and clinical personnel with a safe, real and repeatable operation platform, thereby effectively enhancing their thoracic operation skills. The model is designed based on the anatomical structure of the human chest wall and thoracic cavity, including important layers such as ribs, intercostal Spaces, and pleural cavities, enabling learners to master the correct needle insertion site, direction, and depth in a realistic tactile and resistance feedback environment.

Through repeated practice, students can become familiar with the key steps for handling common emergencies such as pneumothorax, pleural effusion, and hemothorax, reducing risks such as accidental injury to organs and deviation in needle insertion positions during actual operations. Under the guidance of teachers, the model can also be used to explain the key points of connection, fixation and observation of closed thoracic drainage, helping learners systematically understand the entire drainage process.

The application of this model significantly enhances the safety and teaching effectiveness of training, and it is an irreplaceable and important tool in the teaching of emergency medicine, thoracic surgery, critical care medicine and nursing skills.
