ABSTRACT:
A speculum for examining body cavities comprises two angle pieces, each having a generally U-shaped cross-section along substantially its whole length, and consequently troughed-like legs, both angle pieces with their troughs facing each other being removably connectable to each other with side portions thereof on either side of the speculum overlapping each other to form a pivot portion from which the four legs extend, respective legs of the angle pieces being movable together or apart by means of one pair of legs comprised of a leg of each angle piece, serving as handles for operating the other pair, and characterized in that both angle pieces are identically alike and that in the area of the pivot portion, each has on one side a pin and on the opposite side a hole, the hole in each angle piece being made to accommodate the pin of the opposing angle piece.
