Brush for abrading the parietal pleura

A brush for the abrasion of the parietal pleura, the brush comprising:

• a longitudinal body carrying at one of its ends a plurality of strands forming the scraping member,
• a tubular body surrounding the longitudinal body,
• a handle secured to the tubular body and containing longitudinal displacement means of the other body, between at least one working position, in which the working member protrudes out of the free end of the tubular body, and one storage position, in which this member is completely retracted into the tubular body,
• wherein the means for displacing the longitudinal body carrying the strands, are constituted by a manually-actuated slide linked to the posterior end of the longitudinal body, which is opposite to that carrying the strands, said slide being movable in a longitudinal lumen of the handle and cooperating with indexing means carried by the edges of this lumen, whereas the strands include elastically deformable cambers and having different radii of curvature, so as to form, when they are retracted in the tubular body, a bundle of parallel strands and, when they are in the working position, out of the tubular body, a flat fan-shaped brush, whose strands extend laterally from the longitudinal axis.
