[0002] The minimally invasive urological surgery training model is a teaching tool that simulates the human urinary tract system, aiming to help medical students and doctors practice and improve their minimally invasive surgery skills. These models are usually made of highly simulated materials and can simulate real anatomical structures and surgical environments. The minimally invasive urological surgery training model is of great significance for improving doctors' surgical skills, reducing surgical complications, and enhancing the treatment effect of patients.
[0003] When the existing minimally invasive urological surgery training models are manufactured, due to the one-piece manufacturing method, the lesion positions inside the training models are generally fixedly set. At the same time, the interior of the existing training models is relatively dry during use, which is convenient for medical students to operate, making medical students feel familiar with the lesion positions inside the equipment after multiple trainings. However, in actual operations, the body types of different patients may cause the positions of the lesions to change, and the internal environment of the bladder is relatively humid, which is inconvenient for operation, making medical students flustered.
