The laparotomy incision and suture model is a simulation tool used for surgical teaching and operation training. Its main function is to help medical students and clinical personnel master abdominal incision, tissue stratification treatment and suture techniques. Models usually adopt multi-layer simulation materials to simulate structures such as skin, muscles, and peritoneum, making the operation feel close to the real surgical environment.

In teaching, this model can be used to demonstrate the standard incision method, stratified incision and suture sequence of laparotomy, helping students understand the anatomical relationship of different tissue layers and the surgical operation process. In practical training, learners can repeatedly practice the cutting Angle, suture depth and knotting techniques, improving the accuracy of suturing and surgical proficiency, and reducing the operational risks in real surgeries. In addition, the model can also be used for skills assessment and teaching demonstration, providing unified and controllable training standards for colleges and training institutions.

Overall, the incision and suture model for laparotomy is an important tool for basic surgical training, which can significantly enhance students' practical ability and clinical operation level.
