Embodiment

[0033] refer to figure 1 and figure 2 As shown, the present invention provides a thrombus removal device, comprising a catching basket 1 and a hose 2 fixed at the proximal end of the catching basket 1, and a core arranged coaxially with the hose 2 is arranged inside the hose 2 Wire 3, the core wire 3 slides and fits with the hose 2 along the length direction of the hose 2, the core wire 3 is coaxially arranged with the catching basket 1, and the core wire 3 passes through one end of the catching basket 1 Over the catching net basket 1 and slidably fitting with the proximal end of the catching net basket 1, the core wire 3 is fixed on the far end of the catching net basket 1, and the catching net basket 1 is made of a metal wire with good elasticity. Become, when the core wire 3 moved towards the far end of the catching net basket 1, the catching net basket 1 was stressed into a funnel shape.

Abstract

The invention relates to a thrombus taking-out device, which comprises a capturing net basket and a hose fixed to the near end of the capturing net basket, a core wire coaxial with the hose is arranged in the hose, and the core wire is in sliding fit with the hose in the length direction of the hose. The end, facing the catching net basket, of the core wire penetrates through the catching net basket and is in sliding fit with the near end of the catching net basket, the core wire is fixed to the far end of the catching net basket, the catching net basket is made of metal wires with good elasticity, and when the core wire moves towards the far end of the catching net basket, the catching net basket is stressed to be in a funnel shape. The thrombus taking-out device has the advantages that the radial size of the catching net basket after deformation can be changed, so that the thrombus taking-out device adapts to blood vessel environments with different thicknesses, discrete small thrombus in blood vessels can be removed, broken small thrombus blocks are prevented from escaping outwards to other parts of the blood vessels along with blood flow, and damage to the blood vessels is reduced.

Description

technical field [0001] The invention relates to the technical field of interventional treatment equipment, in particular to a thrombus removal device. 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] At present, the common ones on the market can only perform thrombectomy corresponding to the blood vessels at the specified positions, and cannot control the diameter of the thrombus retrieval basket, and cannot be applied to blood vesse...
