<p>A multi-purpose intra-uterine probe for sounding the depth of the fundus and measuring the width of the uterus at two different insertion depths. The later objective is accomplished by an extendable wing mechanism having two stable wing-spreads selectable by means of a ball-point pen-type push-button control mechanism and indicating windows which are color-coded in relation to the rotating push-button of the control mechanism to illustrate the proper sequence of read-out locations. A window reads out the depth of the fundus. The entire uterine probe assembly, including both the flexible wingforming sleeve and the connecting rod which foreshortens the sleeve to collapse it into its wind configurations is a disposable component which removably and replaceably connects to the handle assembly; the wing-forming sleeve connecting to the handle tube, and the foreshortening sleeve connecting to an actuating mechanism which reciprocates the rod relative to the handle tube, and hence relative to the wing-forming sleeve.</p> |
