Thrombus filter for preventing cerebral embolism

Abstract

The invention provides a thrombus filter for preventing the cerebral embolism. The filter comprises a collection part, a collector, a diversion part and a sealing part, the diversion part, the sealingpart and the collection part are integrally formed, so that the diversion part and the sealing part are of a curved structure as a whole; the edges of the diversion part and the collection part are provided with the sealing part; the collection part and the sealing part and the diversion part transit smoothly, the side, facing an arterial branch, of the collection part protrudes, the outer wall of the collection part adapts to the inner wall of the left subclavian artery in the artery branch, a hoop bundle is fixedly connected to the end, away from the diversion part, of the collection part,and the other end of the hoop bundle is detachably connected with the collector. According to the thrombus filter for preventing the cerebral embolism, the structural design is reasonable, embolization materials of the whole filter are drained to the collector and collected through the collector, then collection and filtration are conducted through the collector, the collector is subjected to surgical replacement, not only is the service life of the filter prolonged, but also the phenomenon that the filter influences the blood pressure balance in the body of a patient is avoided.

Description

technical field [0001] The invention relates to the technical field of structural design of a thrombus filter arranged inside the aortic arch of a blood vessel, in particular to a thrombus filter for preventing cerebral embolism and a collector intervention replacement device for preventing cerebral embolism and thrombus filter. Background technique [0002] Embolic material may form in the body following surgery or various organ injuries. These embolic material can travel through the venous system and lodge in the pulmonary or cerebral arteries, causing complications or death. In the prior art, transvenous intervention through the use of filters is a very safe and effective treatment for the prevention of pulmonary embolism, because this device can be partially accessed through the peripheral venous system into the vena cava and thus causes less trauma. [0003] An ideal filter should have: [0004] Can be delivered in the inferior vena cava with a standard vascular cathe...

AI Technical Summary

Problems solved by technology

For young patients, it may be necessary to use the filter for a long time. During long-term use, both the filter itself and the embolic substances filtered by the filter are likely to further form a thrombus with the blood, which will further affect the balance of human blood circulation and endanger human health.

[0011] It can be seen that the filters in the prior art cannot realize surgical cleaning of embolic substances, not only the usable service life of the filter in the patient's body, but also the embolic substances are prone to form thrombus in the human body, which affects the balance of blood circulation in the human body
