Abstract
A method and apparatus for obtaining specimens of endometrial tissue and which comprises an elongate tubular member having a forward end adapted to be inserted into the cervical opening, and a curettage member slideably and rotatably disposed within the tubular member. The curettage member has a blade portion at the forward end and a crank at the rearward end, whereby the blade portion may be advanced into the uterine cavity and rotated about the axis of the cavity to sever tissue specimens along substantially the full length of the cavity. Also, the tubular member includes a connector for coupling a syringe, whereby a solution may be injected into the uterine cavity and subsequently aspirated back into the syringe along with the entrained severed tissue specimens.
