The wrist joint puncture model is a specialized teaching aid used in clinical teaching and skills training. Its main purpose is to help learners master the anatomical positioning and standardized operation of wrist joint puncture in a simulated environment.

The wrist joint, as a common puncture site in clinical practice, is often used for diagnostic joint fluid extraction, drug injection and treatment of intra-articular diseases. Therefore, it has extremely high requirements for the accuracy and sterility of the operation. Through this model, learners can become familiar with the bony landmarks of the wrist joint and the surrounding anatomical relationships, clarify the selection of puncture points and the Angle of acupuncture, and thereby establish an intuitive spatial concept.

During the training process, users can repeatedly practice the operations of needle insertion, fluid aspiration and drug injection, cultivate correct techniques and depth control, and reduce the risk of complications caused by operational errors. In addition, this model can also enhance students' clinical confidence, enabling them to have a solid skill foundation before entering real operations. In conclusion, the purpose of the wrist joint puncture model is to enhance the operational standardization and proficiency of learners and ensure the safety and effectiveness of future clinical practice.
