Nott’s Tri-Valve V. Speculum & Tenaculum c.1865

4.99

Nott’s design consists of a fixed posterior blade to which are hinged, two anterior blades, each independent of the other and each expanding into arms so shaped that they are engaged by a fly-nut acting upon a threaded shaft attached to the lower blade.  By means of this nut, the speculum is opened by divergence of the blade in the amount desired to afford better inspection of the anterior vagina.  1899 Truax.
