APPARATUS FOR TAKING A SMEAR FROM BODY CAVITIES

摘要

1. Curette device for taking swabs from body cavities, comprising a tubular body (1) in which an actuating stem (2) is guided reciprocably and rotatably carrying at least two scrapers (4, 5) capable to being swung out under resilient bias in radial direction by axial movement of the actuating stem relatively to the tubular body, characterised in that the end (7) of the tubular body (1) proximal to the scrapers (4, 5) at its periphery has helical ribs (8).
