Hegar dilators

Hegar Dilators

Hegar dilators (pronounced: heh-gahr dye-lay-tors) are a type of medical instrument used primarily in gynecology and urology to dilate or enlarge an opening or passage in the body. They are named after the German gynecologist August Hegar, who first introduced them in the late 19th century.

Etymology

The term "Hegar dilators" is derived from the name of August Hegar, a German gynecologist who was a pioneer in the field of gynecology during the late 19th century. The term "dilator" comes from the Latin word "dilatare", which means "to enlarge or expand".

Usage

Hegar dilators are used in a variety of medical procedures. In gynecology, they are often used to dilate the cervix during childbirth or prior to certain surgical procedures. In urology, they may be used to dilate the urethra in cases of urinary stricture. They are also used in gender reassignment surgeries.

Design

Hegar dilators are typically made of stainless steel and are double-ended, with each end having a different diameter. This allows for a gradual dilation of the passage. The dilators are usually sold in sets, with each dilator in the set having a slightly larger diameter than the one before it.
