Anoscopes are a traditional medical device commonly used in anorectal departments for examination and treatment. The anus and rectum can be visually observed through the anoscope to see whether the anus and rectum have the pathological changes and the position, the size, the shape and the like of the pathological changes, and the anoscope is a basic method for diagnosing the diseases of the anus and the rectum.

Anoscopes of known type generally comprise a barrel or cone (so-called "speculum") which can be held by the operator by means of a handle and can be introduced (through the anus) into the end segment of the patient's rectum. In the aforementioned speculum which is hollow and open at two opposite ends, a dilator is inserted which is longer than the speculum, is cylindrical, has a substantially rounded end and is provided with a smooth surface.

When the dilator is positioned in the speculum and the speculum is inserted into the rectum, the dilator functions to expand the muscle wall of the rectum without damaging the mucosa of the muscle wall. After insertion of the anoscope, the dilator is removed and the speculum is left inside. In this way, the lumen of the end segment of the rectum is temporarily dilated, thus enabling the easy introduction of other instruments and the performance of diagnostic and/or surgical procedures. However, the length of the speculum of the anoscope is fixed, only one section of the end section of the rectum can be expanded, different section positions of the end section of the rectum cannot be expanded according to requirements, and the length of the rectum of each patient is different, for example, the length of the rectum of adults and children is different, so that the existing anoscope cannot carry out examination, diagnosis and/or surgical operation on the lower section of the anorectum of the patient in all directions and at multiple angles, and the length and the inside and outside can be controlled.
