Portable endoscope Technical Field The invention relates to the technical field of medical instruments, in particular to a portable endoscope. Background With the improvement of life quality and life span, colorectal cancer becomes one of the most common malignant tumors, and screening of colorectal cancer is very important. At present, colonoscopes are usually used for screening colorectal cancer, but the colonoscopes are high in price, high in invasion feeling, complex in intestinal preparation, high in complication risk and the like, and many patients have high resistance to the colonoscopes. In addition, the simplest anus diagnosis method is limited by the length of the fingers of the doctor, so that missed diagnosis is caused, and the method is too dependent on the tactile judgment of the doctor, so that misdiagnosis is caused. The traditional rigid rectoscope is in a straight tube shape, cannot be bent back and is easy to leak the lesion at the anus, has large diameter and strong discomfort, has the risk of affecting the function of the sphincter when the anus is enlarged, and is not suitable for screening the early rectal cancer.
