Abstract

The embodiment of the invention discloses a thrombus aspiration catheter applied to the field of medical apparatuses and instruments. The catheter comprises an aspiration cavity 19, a guide wire cavity 11, a bag body 13, a bag body pressurization passageway 16 and a pipe base 15. The guide wire cavity 11 is a cavity, separated at the end of an aspiration inlet 12, of the aspiration cavity 19. The guide wire cavity 11 comprises a guide wire cavity inlet 18 and a guide wire cavity outlet 14. The guide wire cavity inlet 18 is an inclined plane notch extending out of the aspiration cavity inlet 12. The guide wire cavity outlet 14 is located in any side of the two sides of the bag body. The bag body 13 is located at the end, close to the aspiration cavity inlet 12, of the catheter. The bag body 13 wraps the outer side of the aspiration cavity 19 and the outer side of the guide wire cavity 11. The bag body pressurization passageway 16 is a passageway attached to the aspiration cavity 19. The pipe base 15 is located at the end, close to an aspiration cavity connector 17, of the catheter. The pipe base 15 is connected with the aspiration cavity connector 17. By means of the thrombus aspiration catheter, the aspiration effect and efficiency are greatly improved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a thrombus suction catheter. Background technique [0002] In the field of medicine, the blood vessels of the human body are often blocked by the presence of thrombus, which leads to tissue necrosis in local tissues due to ischemia, which affects human health and even threatens human life. [0003] In order to solve the problem of thrombus blocking blood vessels, in the prior art, a thrombus suction catheter is usually used. By sending the catheter along the blood vessel to the thrombus site, negative pressure is directly applied to extract the thrombus, so that the blood vessel can re-establish hemodynamic force. [0004] However, due to the limited diameter of the blood vessel, the diameter of the suction catheter is also limited, so the effect of suctioning thrombus is often very unsatisfactory. Contents of the invention [0005] The purpose of the present invention is to sol...
