摘要： Disclosed is to isolate cancer cells trapped on a filter without any damage. In a cancer cell isolation device (1), cancer cells X trapped on a filter (100) are captured by a camera (30) as an image capturing unit, and the cancer cells X are carried one by one by using a handling unit (40) while the filter (100) and a storage container (200) are moved by an X-axis movement stand (14), a Y-axis movement stand (16), and a Z-axis movement stand (18) as movement units while the captured image is output from an output unit (32). Accordingly, it is possible to isolate the cancer cells on the filter without damaging the cancer cells and hence to appropriately perform an observation or the like.

摘要： Provided are a cancer cell-trapping metal filter which has a high opening ratio, a cancer cell-trapping metal filter sheet, a cancer cell-trapping device using the cancer cell-trapping filter, and manufacturing methods therefor. According to a cancer cell-trapping metal filter 1, openings of connected through-holes 12 that are formed in a metal sheet 11 have a wave shape, and thus it is possible to extract a CTC from other components by utilizing a hole diameter on a short-side side of the openings, and it is possible to make the connected through-holes be closer to each other due to the wave shape while maintaining a CTC trapping ability. Accordingly, it is possible to further improve the opening ratio in the cancer cell-trapping metal filter 1.
