Problems solved by technology

[0004] First: The balloons are set as a group. When the balloon is stretching a relatively narrow blood vessel, the blood vessel area is filled with blood, which makes the patient's field of vision blocked at the lesion, and it is not convenient to move the balloon to the target position;
[0005] Second: When the balloon is placed inside the blood vessel, there is no handle at the end of the balloon catheter, which is not convenient for the doctor to perform the operation

specific Embodiment approach 1

[0038] Specific implementation mode one: please refer to Figure 1-11 , the present invention provides a technical solution: a series balloon catheter, comprising: a first balloon structure 1, a second balloon structure 4 and a handle structure 6;

[0039] The right side of the first balloon structure 1 is equipped with an adjustment rod 2, and the side of the adjustment rod 2 away from the first balloon structure 1 is installed with a communication tube 3, and the right side of the communication tube 3 is installed with a second balloon structure 4 , and the side of the second balloon structure 4 away from the connecting tube 3 is installed with an air inlet end 5, and the bottom of the air inlet end 5 is installed with a handle structure 6;

[0040] The second balloon structure 4 works in the same way as the first balloon structure 1, and the rear balloon 41 of the second balloon structure 4 is wrapped on the outside of the rear jet tube 42, and the front jet tube 14 is resp...

specific Embodiment approach 2

[0043] Specific embodiment 2: This embodiment is a further limitation of specific embodiment 1. The first balloon structure 1 includes a front balloon 11, a front jet tube 12, an opening 13, a front air tube 14 and a position-limiting gasket 15, and the front Air pipe 14 is placed in the inside of front air injection pipe 12, and the outer surface of front air injection pipe 12 is evenly provided with a plurality of groups of openings 13, and front air pipe 14 is limited by spacer gasket 15 inside front air injection pipe 12.

[0044] Such as Figure 1-2 As shown: the working principle of the first balloon structure 1 is: the gas is ejected from the end of the front air pipe 14, so that the gas enters the inside of the front air injection pipe 12, and the front balloon 11 is lifted up through the opening 13, The front balloon 11 is inflated into an ellipsoid, and the target position is stretched or blocked.

specific Embodiment approach 3

[0045] Specific embodiment three: This embodiment is a further limitation of specific embodiment one. The second balloon structure 4 includes a rear balloon 41, a rear air jet pipe 42 and a rear air pipe 43, and the outer surface of the rear air jet pipe 42 is uniformly opened with multiple Group perforation 13, rear balloon 41 is wrapped on the rear jet pipe 42, rear air pipe 43 end is communicated with rear air connecting pipe 61, and front air pipe 14 end is communicated with front air connecting pipe 62.

[0046] Such as figure 1 and image 3 As shown: the working principle of the second balloon structure 4 is consistent with that of the first balloon structure 1. The rear balloon 41 is placed on the affected area, and the gas enters the inside of the rear jet tube 42 from the end of the rear trachea 43, and the rear jet tube 42 Both sides of the inside of the airtight cavity are sealed by two sets of spacer gaskets 15, so that a closed cavity is formed inside the rear je...

Abstract

The series balloon catheter comprises a first balloon structure, an adjusting rod is installed on the right side of the first balloon structure, a communicating pipe is installed on the side, away from the first balloon structure, of the adjusting rod, meanwhile, a second balloon structure is installed on the right side of the communicating pipe, and an air inlet end is installed on the side, away from the communicating pipe, of the second balloon structure; a handle structure is mounted at the bottom of the air inlet end; the working mode of the second balloon structure is consistent with that of the first balloon structure, and a rear balloon of the second balloon structure wraps the outer side of the rear air spraying pipe. The series balloon catheter is provided with two balloons, namely the front balloon and the rear balloon, one balloon is used for expanding a narrow blood vessel during slow closure and recanalization or severe stenosis, the other balloon is arranged at the far end of the C1 section of the internal carotid artery and can block blood flow, opening and closing of the two balloons can be switched back and forth by pressing the stress strip, and the series balloon catheter has the advantages of being easy to operate, convenient to use and high in practicability. And the operation process is simplified.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a series balloon catheter. Background technique [0002] Endovascular interventional embolization technology is currently the safest and most effective method for the treatment of cerebral arteriovenous vascular malformations; endovascular interventional embolization technology is to obtain vascular access through arterial or venous puncture, and use guide wires, catheters and other instruments to enter the malformation lesion, Then a liquid embolic agent is injected through a microcatheter to seal the lesion, so as to achieve the purpose of treatment; during the embolization process, a small amount of embolic agent usually needs to flow back to block the proximal blood supply artery to ensure better delivery of the embolic agent to the target position Diffusion is carried out; however, there are many risks in the reflux of embolic agents. The reflux enters the blood supply artery ...
