Vintage Stainless Steel Obstetric Pelvimeter

The pelvimeter was invented by Jean-Louis Baudelocque as a refined version of the "pelvic forceps" that came fore.  These anthropometric calipers were used to measure external pelvic dimensions. This distance was to become known as "Baudelocque's diameter" (the external conjugate diameter of the pelvis). 

In 1806 Emperor Napoleon appointed Baudelocque as the first chair of obstetrics in France, and at the same time he began serving as physician-in-chief at the Maternité (later named Maternité Baudelocque), where he taught classes on midwifery. Napoleon also chose him as accoucheur to Empress Marie-Louise and to Caroline Bonaparte, the emperor's younger sister.

This incredibly cool piece would look amazing in your cabinet of curiosities. It measures 31cm in length and can expand to the size of any pelvis!
