An apparatus for removal, by scraping or cutting, of a sample of the internal wall of body cavities and collecting the sample in a container. It consists of a cylindrical container, adapted to be held in one hand and carrying a cannula, the end of which is closed, with a sharp-edged slot being provided closely behind the end. The cannula, during use, is rigidly connected with the container so that it can be manoeuvered therewith using the container as a handle device. The container has a sieve to longitudinally divide the container and to retain the sample, while permitting passage of liquids therethrough, and is connectable with a vacuum tube.
