Abstract

The present invention relates to a metal screen filter for separating cancer cells from blood. The metal screen filter of the present invention is formed with a plurality of filtration holes for filtering cancer cells, such that the gap between two neighboring filtration holes of the plurality of filtration holes is formed to be 45 - 65 % the diameter of a cancer cell, and is installed into a passage having blood flow containing both cancer cells and non-target cells. The diameter of a filtration hole for filtering a cancer cell is 5 - 25 ㎛. According to the present invention, cancer cells can be efficiently and easily separated and collected from large amounts of blood. Additionally, the collection rate of live cancer cells is improved by smooth emission of cancer cells out of a catheter by flow of solution.
