Two cylindrical-shaped glass specula Position of the opened speculum during vaginal examination. Specula have been made of glass or metal. They were generally made of stainless steel and sterilized between uses, but particularly in the 21st century, many — especially those used in emergency departments and doctor's offices — are made of plastic, and are disposable, single-use items.
They are made of inert materials like stainless steel (such as the stainless steel ring (SSR), a flexible ring of steel coils that can deform to be inserted through the cervix) or plastic (such as the Lippes Loop, which can be inserted through the cervix in a cannula and takes a trapezoidal shape within the uterus). They are less effective than ...
The small, flexible inserts are made from polyester fibers, nickel-titanium, stainless steel and solder.
