<p><P>PROBLEM TO BE SOLVED: To surely remove contamination in narrow gaps by a scraper useful for using for cleaning hollow gap portions between parts in devices, narrow gaps of pierce holes boredly formed in human bodies or meatus acusticus externus or others, or pathologic operations or microbiological processes for example, sampling cells in affected sites of patients, or inoculating strains when culturing bacteria. <P>SOLUTION: The whole diameter is suppressed to be small by bringing threads 2 close contact with wire material 1 through spirally winding the threads 2 around the wire materials 1 composed of a flexible raw material, and forming the scraper spirally twisting two or more obtained wire materials with wound threads. The scraping-out condition is improved by increasing hooking to substances to be removed by forming narrow width spiral uneven portions by the wound threads, by forming wide width spiral uneven portions by the wire material with the wound threads, by intersecting the same with each other, and by mixedly including a large number of small and large uneven portions. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
