Abstract: A simplified, easy-to-use surgical scraping instrument or curette especially adapted for obtaining uterine tissue or material samples is provided which includes a suction tube having cooperable scraping loop and tissue-catching structure adjacent one end thereof for easily and safely obtaining tissue samples from the uterine wall of a patient. In preferred forms the material-receiving opening of the tube is generally elliptical in configuration and obliquely disposed adjacent an oppositely and upwardly extending scraping loop presenting a relatively sharp, continuous upper scraping edge. The outermost bight section of the scraping loop is advantageously disposed at an angle relative to the remainder of the loop in order to present an outermost arcuate scraping area.
