Circular excision of superior hemorrhoidal mucosa (also called PPH) is one of the important proposals for surgical operation of hemorrhoids, and a transparent anus dilator is required to be used in the operation to expose the operation visual field. After the anus dilator is guided into the anus anal canal, an operation silk thread is needed to be sewn and fixed at a corresponding position (the position of a window is exposed at the position of 3 points, 7 points or 11 points, for example), at this time, a doctor needs to fix the anus dilator in a knotting mode by using two hands to tie the operation silk thread, when the doctor uses the two hands to tie the silk thread, the anus dilator can be pushed out of the anus anal canal by the force of intestinal peristalsis, and in order to avoid the situation, an assistant is needed to help to press the anus dilator. Specially equipping a surgical assistant for such non-critical operation requirements is a very uneconomical waste of human resources, which makes it urgently necessary to have a dilator that can be fixed by one person.

Furthermore, the existing anal dilator is composed of a cylindrical anal dilator body and an anal dilator seat arranged at the tail part of the anal dilator body. During operation treatment, before the anus dilator is guided into the anus anal tube, the anus tube needs to be fully expanded by the aid of the anus plug and then the anus dilator is placed, and the purpose is to reduce the guiding resistance and difficulty of the anus dilator. However, the use of such auxiliary devices increases the surgical procedure, resulting in resource consumption.
