The advanced digital rectal examination model is a specialized simulation device often used in clinical teaching and skills training. It is mainly used to help medical students and clinicians master the operation norms and diagnostic key points of digital rectal examination. This model is designed based on the anatomical ratio of the human anus and rectum. Its surface material is soft and the internal structure is highly realistic. It can simulate normal rectal anatomy and various common pathological conditions, such as rectal masses, benign prostatic hyperplasia, and hemorrhoid nodules. Through replaceable or adjustable modules, learners can experience the tactile characteristics of different lesions during training, thereby enhancing their clinical discrimination ability.

During the operation, trainees need to follow the clinical standard procedures. First, perform routine hand cleaning and glove wearing. Then, apply an appropriate lubricant to the anal area of the model. Subsequently, slowly enter the rectal cavity with the index finger to simulate palpation of the surrounding rectal wall and internal structure. Through tactile comparison, learners can distinguish normal tissues from abnormal lesions and practice the standardized methods of recording and reporting. Some high-end models are also equipped with electronic feedback systems that can monitor the palpation area and force, enabling teachers to make objective evaluations.

Overall, the advanced digital rectal examination model not only ensures the safety and repeatability of the training process, but also makes up for the shortage of real clinical teaching resources. It provides a scientific, intuitive and standardized training platform for medical students and resident doctors, greatly enhancing their clinical practice ability.
