[0023] Specifically, the sealing assembly 64 includes an annular groove 641 and a sealing ring 644. The sealing ring 644 is provided at the connection between flange one 62 and flange two 63, and the sides of flange one 62 and flange two 63 are provided with annular grooves 641 corresponding to the sealing ring 644.

[0024] By adopting the above technical solution, the annular groove 641 can provide a stable installation position for the sealing ring 644, so that the sealing ring 644 can better fit the flange when under pressure, and further improve the sealing effect.

[0025] Specifically, the sealing assembly 64 also includes a positioning rod 642 and a positioning hole 643. The positioning rod 642 is disposed inside the annular groove 641, and the side of the sealing ring 644 is provided with a positioning hole 643 corresponding to the positioning rod 642.

[0026] By adopting the above technical solution, the cooperation between the positioning rod 642 and the positioning hole 643 can ensure the accurate positioning of the sealing ring 644 during installation, avoid the sealing ring 644 from shifting during installation, and thus ensure the reliability of the seal.

At the same time, the cooperation between the positioning rod 642 and the positioning hole 643 in the sealing assembly 64 ensures the stability of the sealing ring 644, further enhancing the sealing effect and ensuring the safety and effectiveness of the entire aspiration process.

[0028] Example 2

[0029] The difference between this embodiment and Embodiment 1 is that the suction tube fixing mechanism 3 includes an elastic fixing ring 31, a fixing patch 32, an elastic band 33, a medical patch 35, and a medical wound dressing 36. The surface of the tube body 1 is provided with the elastic fixing ring 31, and elastic bands 33 are provided on both sides of the elastic fixing ring 31. A fixing patch 32 is provided at the lower end of the elastic band 33, a medical patch 35 is provided at the upper side of the elastic fixing ring 31, and a medical wound dressing 36 is provided at the lower end of the medical patch 35.

Then, the medical patch 35 is attached to the upper side of the elastic fixing ring 31, and the medical wound dressing 36 is attached to the lower end of the medical patch 35, which plays a protective and fixing role. During thrombus aspiration, the suction tube body 2 can be stably held on the tube body 1 by the fixation of the elastic fixing ring 31 and the elastic band 33, and will not shift due to pressure changes during the aspiration process. At the same time, the presence of the limiting ring 34 further enhances the stability of the suction tube body 2, ensuring the smooth progress of the entire aspiration process. This fixing method is not only easy to operate, but also can be flexibly adjusted according to the physical condition and usage needs of different patients, improving the applicability and safety of the thrombus aspiration catheter.

[0034] The working principle and usage process of this utility model are as follows: First, the suction tube body 2 is inserted into the area where the patient needs thrombus aspiration, ensuring accurate positioning and secure fixation. Then, the thrombus aspiration catheter body 4 is connected to the external aspiration equipment via the connecting tube 5. The aspiration equipment is activated, and the thrombus is aspirated into the suction tube body 2 through the main tube body 1. Due to the sealing mechanism 6, the sealing between the main tube body 1 and the connecting tube 5 is guaranteed, ensuring smooth aspiration without liquid leakage. Simultaneously, the cooperation between the positioning rod 642 and the positioning hole 643 in the sealing assembly 64 ensures the stability of the sealing ring 644, further enhancing the sealing effect and ensuring the safety and effectiveness of the entire aspiration process. The suction tube body 2 is then inserted into the elastic fixing ring 31, and the suction tube body is secured by the elastic band 33 and the fixing sticker 32. The tube body 2 is firmly fixed to the main body 1 of the tubing. The elastic fixing ring 31 can be adjusted appropriately according to the diameter of the tube body 2 to ensure a tight fit. Then, the medical patch 35 is attached to the upper side of the elastic fixing ring 31, and the medical wound dressing 36 is attached to the lower end of the medical patch 35 to provide protection and fixation. During thrombus aspiration, the tube body 2 can be stably held on the main body 1 of the tubing through the fixation of the elastic fixing ring 31 and the elastic band 33, and will not shift due to pressure changes during the aspiration process. At the same time, the presence of the limiting ring 34 further enhances the stability of the tube body 2, ensuring the smooth progress of the entire aspiration process. This fixing method is not only easy to operate, but also can be flexibly adjusted according to the physical condition and usage needs of different patients, improving the applicability and safety of the thrombus aspiration catheter.
