The surgical knotting skills training model is a simulation teaching aid specifically designed for the training of basic surgical operations, aiming to help learners master the basic methods of suturing and knotting as well as hand coordination. This model is usually made of flexible simulation materials and can simulate the texture of skin, blood vessels or tissues. Some designs are equipped with incisions or fixed structures to enable learners to practice in different scenarios.

The usage method is generally divided into the following steps: First, the learner needs to select the appropriate suture thread and needle holder according to the training requirements and determine the practice area on the model. Subsequently, needle threading, thread pulling and knotting were carried out in accordance with the surgical operation norms. Common training contents include one-handed knots, two-handed knots and machine knots, etc. Through repeated practice, learners can master the coordination of movements and the stability of line knots.

During the training process, special attention should be paid to the force and direction when tying knots to ensure that the knots are tight and do not damage the "tissue". Some models can also be sutured and untied multiple times, facilitating repeated operation and error correction, and enabling learners to gradually form muscle memory.

Through the repeated use of the surgical knotting skills training model, learners can establish standardized operation habits in a risk-free environment, laying a solid foundation for practical application in future clinical surgeries. This not only enhances the surgical skills but also has positive significance in ensuring patient safety.
