The rectal examination operation model is an important simulation teaching aid used in medical teaching and clinical skills training. It is mainly used to train medical students and nursing staff to master digital rectal examination, digital rectal examination and related operation skills. This model is designed based on the anatomical proportions of the human rectum, anus and surrounding structures. Its surface texture is close to real skin, and its internal structure includes the rectal lumen, anal canal and surrounding tissues of the rectum, which can visually display the position of the rectum and the palpation sensation.

In the operation training, learners first master the anatomical positions of the anus and rectum by observing the shape of the model. Subsequently, digital examination training was carried out in accordance with the standardized operation procedures to sense the hardness, elasticity inside the model and the pathological simulation sites (such as hemorrhoids, polyps, masses, etc.), gradually improving the accuracy and sensitivity of palpation. The model can be reused multiple times, enabling students to master the operation techniques and force control proficiently in a risk-free environment.

In addition, this model is suitable for teachers' demonstrations and classroom explanations, closely integrating theoretical knowledge with practical operations. Some advanced models are also designed with replaceable lesion modules to help learners understand the key points of examination under different pathological conditions and enhance their clinical judgment ability.

Overall, the rectal examination operation model not only provides learners with a safe and repeatable practice platform, but also effectively enhances the efficiency and accuracy of clinical skills training, making it an indispensable auxiliary tool in medical education.
