Problems solved by technology

If the effect of thrombus suction is not good, there is floating thrombus in the local area or the local outflow tract is narrow, balloon angioplasty or stent implantation will be performed, which will increase the economic burden of the patient, and the long-term effect is not clear, and there will be restenosis in the stent risk, making further treatment or surgery difficult

Embodiment 1

[0062] like figure 1 As shown, a novel thrombus suction composite balloon system in this embodiment includes a guide tube 1 and a suction tube 2, and the guide tube 1 is arranged inside the suction tube 2, and the guide tube 1 includes for sealing. The thrombus interception structure of the remote vessel is located, the thrombosis intercepting structure is located at the distal end of the guide tube 1; the suction tube 2 includes a vascular supporting structure and a negative pressure suction structure, and the angiographic structure is disposed at the distal end of the suction tube 2, negative The pressure suction structure is disposed at the proximal end of the suction tube 2. The thrombocution intercepting structure in the present invention can intercept the thrombus that is softened, floated, and prevents the thrombus with blood flow to cause thromboembolism.

[0063] The guide tube 1 and the suction tube 2 are cylindrical; the length of the guide tube 1 is larger than the len...

Embodiment 2

[0073] like Figure 2-7 As shown, on the basis of the first embodiment, the thrombus intercepting structure and the conveying structure are specifically set:

[0074] The umbrella airbag includes only the filtration membrane 111 that allows blood to pass through, and the filter film 111 is integrated with the umbrella airbag. Such settings can cause a small amount of blood to flow through the filter membrane 111 to ensure circulation of blood.

[0075] The filter membrane 111 is disposed on the edge of the umbrella airbag, the edge of the filter film 111 contacts the inner wall of the blood vessel. This setting expands the interception range of the umbrella airbag, which has played a full interception of thrombosis.

[0076] The filter membrane 111 is made of soft material. This setting can protect blood vessels to avoid damage to blood vessels.

[0077] Alternatively, the filter membrane 111 is made of a biocompatible material.

[0078] The guide tube 1 also includes a conveying s...

Embodiment 3

[0085] like Figure 8-9 As shown in the basis of the second embodiment, the present embodiment has a specific setting of the support airbag: the angioplastically open structure is a support of the airbag, the side wall of the suction tube 2 includes a airway 22 in communication with the support of the airbag, support the airbag and pumping The straw 2 is fixed. The support airbags open the ventricular vessels of thrombus to provide a large suction space for suction thrombosis.

[0086] The opening of the airway 22 is located on the proximal side wall of the suction tube 2, and the inflation tube 2 23 communicates with the airway 22 at an opening at the opening of the airway 22, and the inflatable tube 2 23 is integrated. By inflating to the airway 22, the support airbag is filled, and the airbag is discharged.

[0087] The opening end of the inflator 23 includes a reinforcing tube 231, and the opening end of the reinforcing tube 231 includes a sealing plug 2 232, and the sealing pl...

Abstract

The invention discloses a novel thrombus aspiration composite balloon system. The system comprises a guide tube and an aspiration tube, wherein the guide tube is sleeved with the aspiration tube, the guide tube comprises a thrombus intercepting structure used for blocking a distal blood vessel, and the thrombus intercepting structure is located at the distal end of the guide tube; and the aspiration tube comprises a blood vessel opening structure and a negative pressure suction structure, the blood vessel opening structure is arranged at the distal end of the aspiration tube, and the negative pressure suction structure is arranged at the proximal end of the aspiration tube. The thrombus intercepting structure can intercept thrombus softened and floating by negative pressure, and thrombus embolism caused by the fact that the thrombus flows along with blood is prevented.

Description

Technical field [0001] The present invention belongs to the technical field of medical devices, and is specifically related to a new thrombus suction composite balloon system. Background technique [0002] Those is mainly divided into two kinds, one is to draw blood in the use of catheters, and the catheter is reached inside the thrombus, and the thrombosis is relatively inexpensive. The prices are relatively inexpensive, the suction effect is mainly according to the catheter The diameter is determined that if the catheter is relatively thick, the suction effect is better. The other is mechanical suction, there is a dedicated hydrocarrier, and is also entered into the thrombus through the blood vessel, and the drug is injected into the thrombolytic drug in the thrombus, and the drug will be dissolved for a while, and then the machine will be opened. Soft thrombus that has been dissolved is suck in vitro. [0003] Mechanical thrombosis suction is considered to be a new type, safe,...
