ABSTRACT:
An endometrial tissue-obtaining instrument includes a spiral section formed at one end of a flat plastic member and a handle portion at the other end. The spiral section is insertable into the womb of a female patient and rotated by the handle portion to remove endometrial tissue from the wall of the womb. The spiral section is withdrawn with the specimen of tissue.
The trailing portion of the spiral section is inserted into a slot of a plastic paddle and pulled away from the paddle so that the spiral section moves through the slot and is rotated thereby. The thickness of the slot permits the wiping, or extruding, of the tissue from the spiral section onto the paddle whereafter the paddle is manipulated to deposit the tissue onto a slide or stored for future purposes.
