Uterine Sounds consist of slender, rod-like instruments employed to measure the depth and direction of the uterine cavity, as a lever to correct displacements, and as a means for determining the presence and extent of uterine growths.  Generally constructed of soft copper, rigid brass, spiral steel, or aluminum, somewhat curved at the distal end and bulb-pointed, the proximal end terminating in a flat handle, one side of which is corrugated to reflect the direction of the curve.  They may be obtained in either plain or graduated in inches. A splendid and rare example of Leonard’s Uterometric Sound by New York maker Tiemann & Co., graduated, with spiral steel sliding gauge, hard rubber handle and copper tip, FC.
