The surgical suture and bandaging demonstration model is a practical tool used for surgical skills teaching and clinical training, mainly to help learners master suture techniques and bandaging methods. Models are usually made with simulated skin and tissue layers, which can present skin, muscle and blood vessel structures of different thicknesses, making needlework operations closer to the real feel.

In teaching, this model can be used to demonstrate various suture methods, such as single-layer suture, continuous suture, intermittent suture, etc., as well as bandaging techniques for different types of wounds, helping students understand the operation steps, suture spacing and force control. In clinical skills training, learners can repeatedly practice the Angle of needle insertion, suture force and knotting technique, improving their proficiency and accuracy in operation, while reducing the risks when operating on real patients.

Overall, the surgical suture and bandaging demonstration model is an important auxiliary tool for basic surgical training and skills assessment, which can effectively enhance students' practical ability and clinical practice level.
