The minimally invasive thrombus aspiration method can extract acute thrombus, but it cannot deal with subacute and chronic thrombus, let alone tumor thrombus, and there is a risk of thrombus easy to fall off and cause remote embolism; minimally invasive catheter thrombolysis method It can dissolve acute thrombus and some subacute thrombus, but it can’t deal with tumor thrombus, and there is a high risk of bleeding and thrombus dislodging, which may lead to remote embolism
[0003] In summary, it is difficult to deal with tumor thrombi in the prior art, and there is a risk that the thrombus is easy to fall off during thrombus removal, resulting in distal embolism

Embodiment 1
[0045] The thrombus removal device for the aorta and its branch arteries provided by the present application, on the one hand, can collect the tumor thrombus when the thrombus retrieval balloon assembly drags the tumor thrombus to the aorta, so as to realize the thrombus removal of the tumor thrombus; on the other hand , It can also effectively prevent the risk of distal embolism during thrombectomy.
[0046] Such as figure 1 , figure 2 and image 3 As shown, the present application provides a thrombectomy device for the aorta and its branch arteries, including: a guide tube 10 , a guide wire tube 20 , an outer sheath 30 and a collection assembly 40 .
[0047] The function of the guide wire tube 20 is to pass through the hard guide wire 50. The guide wire tube 20 is installed in the guide tube 10, and the front end of the guide wire tube 20 protrudes from the guide tube 10. When used, the guide wire tube 20 is required It is fixedly connected with the guide tube 10, so tha...
Embodiment 2
[0069] Such as Figure 6 and Figure 7 As shown, the embodiment of the present application provides an aortic thrombectomy system, which includes a thrombectomy balloon assembly 60, a hard guide wire 50, and the thrombectomy device provided in the first embodiment above (which may be the first The thrombectomy device of a kind of structure, also can be the thrombectomy device of the second kind of structure).
[0070] It should be noted that since the structure of the thrombectomy device has been described in the first embodiment, it will not be repeated in this embodiment.
[0071] The thrombus retrieval balloon assembly 60 is used to drag the thrombus or tumor thrombus in the branch artery into the aorta;
[0072] The hard guide wire 50 is passed through the guide wire tube 20 of the thrombectomy device, and under the guidance of the hard guide wire 50, the thrombus removal device enters the aorta, and then passes through the filter sleeve 41 to remove the thrombus or tumo...

Abstract
The invention provides a thrombectomy device and a thrombectomy system for aorta and branch arteries thereof and belongs to the field of medical instruments. The thrombectomy device for aorta and branch arteries thereof comprises a guide tube, a guide wire tube, a sheath and a collection assembly, wherein the guide wire tube penetrates through the guide tube, and the front end of the guide wire tube extends out of the guide tube; the collection assembly is arranged at the front end of the guide wire tube and comprises a filter net sleeve arranged on the guide wire tube, an elastic ring and binding wires; the net bottom of the filter net sleeve is arranged on the outer wall of the guide tube, and the net opening of the filter net sleeve surrounds the elastic ring; one ends of multiple binding wires are connected with the elastic ring, and the other ends penetrate through the guide wire tube to be led to the outside of the guide wire tube; and the sheath is arranged on the outer side ofthe guide tube and can move in the length direction of the guide tube so as to retract or release the collection assembly. The thrombectomy device can cooperate with a thrombectomy balloon assembly totake out tumor embolus and effectively prevent the risk of far-end embolism in a thrombectomy process.
Description
technical field [0001] The invention relates to the field of medical devices, in particular to a thrombus removal device and a thrombus removal system for an aorta and its branch arteries. Background technique [0002] Embolic lesions of the aorta and its primary branches have always been a difficult point in vascular surgery. The minimally invasive thrombus aspiration method can extract acute thrombus, but it cannot deal with subacute and chronic thrombus, let alone tumor thrombus, and there is a risk of thrombus easy to fall off and cause remote embolism; minimally invasive catheter thrombolysis method It can dissolve acute thrombus and some subacute thrombus, but it cannot deal with tumor thrombus, and there is a high risk of bleeding and the risk of distal embolism caused by thrombus falling off. [0003] In summary, it is difficult to deal with tumor thrombi in the prior art, and there is a risk that the thrombus is easy to fall off during thrombectomy, resulting in di...
