This invention discloses a cell cluster separation device and its usage method in malignant pleural effusion, belonging to the field of cell separation technology. By having two locking blocks approach each other and disengage from the locking groove, the locking state between the support base and the mounting base is released, allowing the support base and multiple centrifuge tubes to be removed from the centrifuge. When removing the centrifuge tubes, because the central axis of the tube rack and the support base is parallel, the centrifuge tubes can be directly pulled vertically upwards, facilitating the simultaneous removal of multiple centrifuge tubes. The downward movement of the conical seat can compress the two locking blocks, causing them to engage in the locking groove, thus achieving the purpose of locking the support base and the mounting base. Therefore, the modular design of the centrifuge, support base, and tube rack enables the rapid loading and unloading of batches of centrifuge tubes. The use of two sets of support bases and multiple tube racks for centrifugation allows for alternating loading and unloading of centrifuge tubes, shortening the time spent loading and unloading centrifuge tubes and facilitating the efficient and stable separation of cell clusters.
