The wrist puncture model plays a vital role in medical education and training, supporting a variety of specific puncture training procedures designed to help students master the wrist puncture technique and improve the accuracy and safety of clinical procedures. The following are the main puncture training operations supported by the wrist puncture model:

1. Simulation of intracavitary injection therapy in the wrist

The wrist puncture model can simulate the operation process of intracavitary injection therapy. Participants can perform simulation training on the wrist cavity injection on the model, including locating the puncture point, inserting the needle, draining the fluid (if any), and injecting the drug. This training helps students familiarize themselves with the anatomy of the wrist joint, master piercing techniques, and learn how to select the appropriate piercing method and treatment medication according to the patient's condition.

Two, multi-site puncture training

The wrist joint puncture model usually includes multiple sites for puncture, such as carpal tunnel, first metacarpal osteoarthritis, radial styloid tenosynovitis, flexor tendon tenosynovitis, etc. The Settings of these puncture areas allow the model to simulate the puncture treatment process for a variety of wrist diseases. Students can perform puncture training on different parts of the model to master various puncture techniques and methods and improve their ability to cope with different diseases.

3. Real-time feedback and evaluation

Some advanced wrist puncture models are also equipped with real-time feedback and evaluation systems. When the student performs the piercing operation, the model can give corresponding feedback signals based on the accuracy and depth of the piercing. For example, if the puncture is positioned correctly, the control box on the model will light green; If the needle is inserted correctly but does not reach the joint cavity, the yellow light is on; If important structures such as nerves or blood vessels are touched, a red light will go on. This real-time feedback mechanism helps students to adjust puncture techniques in time and improve the accuracy and safety of puncture.

Fourth, comprehensive training and assessment

The wrist joint puncture model not only supports single puncture training operation, but also can be combined with other medical teaching models for comprehensive training and assessment. For example, students can perform wrist puncture operations in a scenario that simulates a real clinical environment to test their mastery and application of puncture techniques.

In summary, the wrist puncture model supports a variety of specific puncture training operations, including simulation of intracavicular injection therapy, multi-site puncture training, real-time feedback and evaluation, and comprehensive training and assessment. These training procedures help students to fully master the wrist puncture technique and improve the accuracy and safety of clinical operations.
