ABSTRACT:
A generally conventional speculum including first and second elongated transversely arcuate blades opening toward each other and defining a longitudinal housing therebetween as provided. Mounting structure pivotally connects base ends of the blades for relative swinging of the free blade ends toward and away from each other and enables adjustable lateral shifting of the axis of relative pivoting of the blades toward and away from one of the blades. The mounting structure is operative to adjustably limit swinging of the free blade ends toward each other and an elongated rod is disposed between the blades and extends through the housing with a first end of the rod cradled in the base end of the other blade for longitudinal shifting of the rod relative to the other blade with clamp structure provided for releasably rigidly anchoring the rod in adjusted longitudinal shifted position. The free end of the rod is inclined away from the free end of the other blade toward the free end of the aforementioned one blade when the blades are generally parallel and an abutment is carried by and shiftable along the rod and may be releasably retained in adjusted position therealong. An elongated handle is supported from the base end of the aforementioned one blade and extends generally at right angles relative thereto with the handle projecting substantially directly away from the other blade.
