The invention belongs to the technical field of auxiliary equipment for the anorectal department, in particular to an
anal fissure prevention
rectum sight glass for the anorectal department, and aims at solving the problem that the
anal fissure prevention function is not achieved. The following scheme is provided: the
rectum sight glass comprises a circular shell, and a
rectum sight glass main body is transversely arranged in an inner cavity of the circular shell; the right side of the rectum
sight glass body penetrates to the right side of the circular shell, arc-shaped grooves are formed in the top and the bottom of the circular shell, arc-shaped top blocks are arranged in inner cavities of the arc-shaped grooves, weather-proof
layers are arranged on the surfaces of the arc-shaped top blocks, and lubricating
layers are arranged on the sides, away from the arc-shaped top blocks, of the weather-proof
layers. And shells are fixedly connected to the left side of the top and the left side of the bottom of the inner cavity of the circular shell correspondingly, by arranging a guide groove, a
pulley and a fixed column, the effect of stable movement is achieved when the movable column is used, the stability performance of the movable column is improved, and the problem that the movable column is likely to shake when used is solved.
