A culdoscope is a type of medical instrument used in gynecology to examine the pelvic cavity. It is a type of endoscope, which is a flexible or rigid tube with a light and camera attached to it, allowing the visualization of internal organs. The culdoscope is inserted through the vagina and into the pelvic cavity, providing a view of the ovaries, fallopian tubes, uterus, and other structures in this area. This procedure is called a culdoscopy and it can be used for diagnostic purposes, such as identifying abnormal growths or lesions, or for therapeutic purposes, such as removing scar tissue or taking biopsies.
