The first connecting rods 51 are evenly distributed on the collar 5. The first receiving tanks 3 and the second receiving tanks 4 are both connected to the filtering devices 2. The first receiving tanks 3 and the second receiving tanks 4 are respectively connected to a conduit.

[0035] The filter device 2 includes a first tank 21, a second tank 22 and a filter plate 23. The first tank 21 is provided with a connecting groove, the second tank 22 is provided with a connecting part 221, and the filter plate 23 is placed in the connecting groove and clamped between the connecting groove and the connecting part 221.

[0036] The first tank 21 has a liquid outlet at the bottom and the second tank 22 has a liquid inlet at the top. The first receiving tank 3 is threaded to the liquid inlet and the second receiving tank 4 is threaded to the liquid outlet. The first receiving tank 3 is equipped with a valve located at the connection between the first receiving tank 3 and the liquid inlet.

[0037] The first connecting rod 51 is provided with a first gripper 52, which clamps the first tank body 21.

[0038] The first tank body 21 is provided with a protrusion 26, and the protrusion 26 is provided with a through groove. The second tank body 22 is provided with a connecting block 24, and the connecting block 24 is provided with an insertion rod 25 corresponding to the through groove. The side wall of the insertion rod 25 is provided with a first movable groove, and a fixing block 28 is provided in the first movable groove. The fixing block 28 is provided with a connecting spring 281, one end of the connecting spring 281 is fixed to the inner wall of the first movable groove, and the bottom of the fixing block 28 is provided with an inclined groove.

[0039] The insertion rod 25 is provided with a second movable groove, which communicates with the first movable groove. The depth of the second movable groove is less than the depth of the first movable groove. A push plate 29 is provided in the second movable groove. A second connecting rod 27 is provided on the push plate 29. A movable ring 210 is provided on the second connecting rod 27. The movable ring 210 is sleeved on the second tank body 22 and can move along the side wall of the second tank body 22.

[0040] The top of the mounting rod 1 is provided with a third movable groove, and a first movable rod 6 is provided in the third movable groove. The first movable rod 6 can move along the inner wall of the third movable groove. A third connecting rod 61 is provided on the first movable rod 6, and a second gripper 62 is provided on the third connecting rod 61. The second gripper 62 clamps on the first receiving tank 3. The bottom of the mounting rod 1 is provided with a fourth movable groove, and a second movable rod 7 is provided in the fourth movable groove. The second movable rod 7 can move along the inner wall of the fourth movable groove. A fourth connecting rod 71 is provided on the second movable rod 7, and a third gripper is provided on the fourth connecting rod 71. The third gripper clamps on the second receiving tank 4.

[0041] Mounting rod 1 is provided with a fifth connecting rod 8, and the fifth connecting rod 8 is provided with a tightening ring 81. Mounting rod 1 is connected to other equipment through tightening ring 81.

[0042] The extracted blood first enters the first receiving tank 3 and then the filter device 2, where the blood is filtered to remove blood clots. When too many blood clots clog the filter plate 23, the valve on the first receiving tank 3 is closed, and the blood is temporarily stored in the first receiving tank 3. The first receiving tank 3 and the second receiving tank 4 are then removed from the filter device 2, and pushed to move them away from the filter device 2. The collar 5 is rotated to move another filter device 2 between the first receiving tank 3 and the second receiving tank 4, so that the first receiving tank 3 and the second receiving tank 4 are connected to the new filter device 2, ensuring the continuous operation of the thrombectomy.

[0043] The threaded connection allows for quick assembly and disassembly of the receiving tank and the filter device 2, minimizing the impact of clogging of the filter plate 23 and facilitating blood recovery.

[0044] When replacing the filter plate 23, push the movable ring 210 upwards. The movable ring 210 drives the push plate 29 to move. The push plate 29 abuts against the inclined groove of the fixed block 28 and pushes the fixed block 28 into the first movable groove. Remove the second tank 22 from the first tank 21, and the filter plate 23 can be replaced directly. After the filter plate 23 is replaced, insert the connecting part 221 of the second tank 22 into the connecting groove. Align the insert rod 25 with the through groove and insert it into the through groove. Push the movable ring 210 downwards. The push plate 29 moves to below the fixed block 28. The fixed block 28 extends out from the first movable groove and abuts against the bottom surface of the through groove. The second tank 22 is fixed on the first tank 21, so that the filter device 2 can be put back into use.
