ABSTRACT:
An equine speculum has an extension (17b) to the upper jaw piece (17a) to which the speculum-controlling handle (28a) is joined by a pivot (30), there being a slot (44) in the handle to permit relative motion of a pivot (29) that joins the handle to the lower jaw piece (18). An extension (46) below the lower jaw piece provides additional teeth (47) to permit latching the speculum in various open positions.
