Abstract
A speculum for vaginal examination incorporates pin-and-slot connections between the upper and lower blades to enable individual or simultaneous adjustment of speculum aperture and blade angulation by simple application of thumb pressure on the upper blade handle. Small hinge pins on each side of the lower blade handle are pivotably and slidably received within corresponding slots on opposite sides of the upper blade handle. A single covering nut threaded on preferably the right-hand side hinge pin controls locking and releasing of the blades relative to one another for both phases of adjustment. Loosening the covering nut releases the blades for adjustment of angulation and/or aperture as desired, whereas tightening of the nut locks the blades in the desired configuration.
