Rectal dilator

A rectal or anal dilator is a medical device similar to a speculum designed to open and relax the internal/external anal sphincter and rectum in order to facilitate medical inspection or relieve constipation.[1] One early version of a rectal dilator was Dr. Young's Ideal Rectal Dilators, invented in 1892.
