A circulating tumor cell capture device (5), comprising: one or more containers for use in treating a collected circulating tumor cell; an inner wall of a container is fitted with an antibody which may specifically bind with the circulating tumor cell, or is fitted with a nanoparticle having a surface which is modified with an antibody. The container is a spiral container or a straight cylinder having a threaded structure, which may cause liquid flowing into an inner portion of the container to advance in a spiral, thereby generating centrifugal force. Circulating tumor cells may produce a greater centrifugal force relative to red blood cells and platelets, and thus specifically bind to the antibody on the container wall. By means of a combination of two mechanisms, the present invention may achieve the capture of a circulating tumor cell (CTC) in the blood and reduce the probability of tumor metastasis; at the same time, a CTC which is enriched on the inner wall of the container may be collected for further characterization and study.
