A dual container-type balanced lavage apparatus of a thrombus remover. The apparatus comprises a liquid inlet pipe (1), a liquid outlet pipe (2), pump number one (3), pump number two (4), container number one (5), and container number two (6). Container number one (5) is connected to a high-pressure cavity (7) of a debris aspiration apparatus in the thrombus remover via the liquid inlet pipe (1) and pump number one (3), while a low-pressure cavity (8) of the debris aspiration apparatus is connected to container number two (6) via the liquid outlet pipe (2) and pump number two (4). Arranged on the liquid inlet pipe (1) between pump number one (3) and the high-pressure cavity (7) of the debris aspiration apparatus is flexible pipe section number one (101) for use in cushioning pressure waves generated by pump number one (3). Arranged on the liquid outlet pipe (2) between the low-pressure cavity (8) of the debris aspiration apparatus and pump number two (4) is flexible pipe section number two (201) for use in cushioning pressure waves generated by pump number two (4). The arrangement of flexible pipe sections number one and two (101 and 201) respectively on the liquid inlet pipe (1) and on the liquid outlet pipe (2) allows for use of the flexible pipe walls of each to cushion the pressure waves generated by pumps number one and two (3 and 4), thus facilitating increased operation stability of the entire apparatus.
