Definition for Pederson speculum
From Biology Forums Dictionary
The Pederson speculum is a vaginal speculum used during pelvic examinations. This flat, narrow speculum is designed for use in women who have narrow vaginal canals. Narrow vaginal canals can be caused by traumatic injuries and scar tissue. They are also found in elderly women and women who have never had sexual intercourse. Using this narrow speculum can eliminate some of the discomfort of a pelvic exam and make it easier to visualize internal structures to ensure they are normal in size and shape. The Pederson speculum is available in metal and plastic.
