Abstract
A uterine curette device for curetting the endometrial lining the uterus using a cannula having a hollow curetting head including at least one longitudinal blade and corresponding slot through which endometrium can be suctioned into the curetting head. The at least one longitudinal blade bowing outward and having two margins with at least one margin having a curetting edge where the margin meets the outer surface of the curetting head. Endometrium is curetted by rotating the cannula about its longitudinal axis so that the at least one curetting edge curettes off the endometrial sample which is then suctioned into the cannula.
Claims15
An elongate hollow cylindrical endometrial tissue curette for removing an endometrial tissue lining a uterus, the curette comprising:
- a longitudinally elongate hollow curetting head, at a distal end of the curette, having a longitudinal axis and an outside surface extending longitudinally to a substantially rounded tip and an inside surface defining a hollow interior, the curetting head having at least one substantially longitudinally oriented blade, the at least one blade bowing outward radialward from the longitudinal axis with at least a portion of the blade extending into the substantially rounded tip and comprising at least two substantially longitudinal margins defining at least one substantially longitudinally oriented space there between and through the hollow curetting head and providing a direct communication from the hollow interior to the outside of the elongate hollow curetting head;
- at least one curetting edge formed on at least one of the at least two substantially longitudinal margins at the outside surface;
- and
- suction means for creating a suction in the hollow curetting head at the at least one space to suctionably draw an endometrial tissue sample into the space between the at least two margins;
- whereby rotating the elongate hollow cylindrical endometrial tissue curette around its longitudinal axis rotates the at least one curetting edge curetting the tissue sample free from the lining of the uterus and suctioning the tissue sample into the hollow curetting head.
