Abstract

The invention relates to the technical field of medical instruments, and discloses a net basket type thrombus removing device. The device comprises a far-end filtering disc, a near-end recycling discand at least one middle thrombus taking disc; the far-end filtering disc can be elastically expanded in the radial direction, and is provided with a net-shaped structure; the far-end filtering disc, the middle thrombus taking disc and the near-end recycling disc are sequentially and coaxially connected; in a natural unfolding state, the middle thrombus taking disc is in a flat disc shape; and thediameter of the middle thrombus taking disc is larger than that of the far-end filtering disc. According to the embodiment of the invention, a rapid, safe and effective thrombus removing mode can be provided for embolism treatment of pulmonary artery embolism and other large-size and thrombus-amount embolism, so that the treatment effect of acute middle-high risk pulmonary embolism patients can beimproved.

Description

Technical field

[0001] The present invention relates to the technical field of medical devices, in particular to a net basket thrombus removal device.Background technique

[0002] Pulmonary embolism (PE), a clinical pathophysiological syndrome (PE) in which various emboli of the systemic circulation falls off and blocks the pulmonary artery and its branches and causes pulmonary circulatory disorders. It is one of the three most fatal cardiovascular diseases that are parallel to myocardial infarction and stroke. The most common pulmonary embolism is thrombosis. Pulmonary embolism caused by thrombosis is also called pulmonary thromboembolism (PTE). Nowadays, intravascular interventional therapy has gradually become a trend in the treatment of endovascular diseases, but the treatment of patients with acute pulmonary embolism currently lacks effective interventional therapy in clinical practice. At present, the treatment of vascular embolism products on the market are mainly for clinical appl...
