The significance of the emergence of wrist joint puncture models

The emergence of the wrist joint puncture model has provided a safe and repeatable practice platform for clinical teaching and skills training, which has significant teaching significance. This model is designed based on the anatomical structure of the real wrist joint, including the joint cavity, bony landmarks and soft tissue layers. It enables learners to practice the positioning of puncture paths, the control of needle insertion angles and the operation of joint fluid extraction in a risk-free environment.

Through repeated training, students can become familiar with key palpation points such as the radial styloid process and the ulnar styloid process, improve their spatial judgment of the position of the wrist joint cavity, and reduce errors and the risk of complications in actual operations. In clinical training, teachers can also use models to explain the indications and precautions for puncture in common wrist joint diseases (such as synovitis, tenosynovitis, and joint effusion), enabling learners to have a clearer understanding of the clinical significance behind the operation.

In addition, this model also helps to enhance the clinical confidence of interns and prepare them for entering the real diagnosis and treatment environment. It is an indispensable teaching tool in orthopedics, rehabilitation and nursing skills training.
