Embodiment

[0034] refer to figure 1 and figure 2 As shown, the present invention provides a peripheral thrombectomy basket, comprising a plurality of coaxially arranged thrombus retrieval baskets 1 and core wires 2, and the core wires 2 pass through multiple thrombectomy baskets 1 in turn toward one end of the plurality of thrombus retrieval baskets 1. A bolt-removing basket 1 is slidably matched with the distal end of the bolt-removing basket 1, and the core wire 2 is welded on the proximal end of the bolt-removing basket 1, and the bolt-removing basket 1 is made of a metal wire with good elasticity. A plurality of the bolt-removing baskets 1 are arranged at intervals.

[0035] When removing the thrombus, a plurality of thrombus removal baskets 1 are accommodated in the microcatheter. Due to the external force in the radial direction, the thrombus removal basket 1 is pulled in an elongated shape, and the microcatheter is transported to the lesion, passes through the thrombus, and retu...

Abstract

The invention relates to a peripheral thrombectomy mesh basket, which comprises a plurality of thrombectomy mesh baskets and a core wire which are coaxially arranged, the end, facing the thrombectomy mesh baskets, of the core wire sequentially penetrates through the thrombectomy mesh baskets and is in sliding fit with the far ends of the thrombectomy mesh baskets, the core wire is fixed to the near ends of the thrombectomy mesh baskets, and the thrombectomy mesh baskets are made of metal wires with good elasticity; and the plurality of thrombectomy mesh baskets are arranged at intervals. The peripheral thrombectomy mesh basket has the advantages that the front-back working length of the whole peripheral thrombectomy mesh basket is controllable, the peripheral thrombectomy mesh basket can be used for removing long thrombus in blood vessels, the contact area between the peripheral thrombectomy mesh basket and the thrombus is wider when the thrombus is captured, the capturing force on thrombus blocks is higher, and damage to the blood vessels is smaller.

Description

technical field [0001] The invention relates to the technical field of interventional machinery, in particular to a peripheral thrombectomy basket. Background technique [0002] Vascular interventional technology is an important method for the diagnosis and treatment of vascular diseases. It has many advantages such as minimally invasive, less pain for patients, quick recovery, definite curative effect, and no need for blood transfusion. However, in the process of vascular interventional treatment, the catheter and guide wire sometimes twist, break and fall off. These foreign bodies remaining in the patient's blood vessels may cause a series of complications, so the foreign bodies remaining in the blood vessels must be removed . [0003] Although the existing thrombectomy device can remove the thrombus in the blood vessel, it cannot be used to remove the thrombus with a long length due to the limited length of the entire thrombus removal stent during use. Contents of the ...
