Technical Field

[0001] The utility model relates to the field of medical devices, and particularly to an expandable support isolation balloon. Background Art

[0002] As a recognized treatment method, balloon dilation is widely used in the medical field for the treatment of diseases such as cardiovascular diseases and digestive tract stenosis. With the progress and development of technology, the application range of balloons has become more and more extensive; therefore, the shape, size and performance requirements of balloons have become more and more diverse.

[0003] The surface of a conventional isolation balloon bulges due to the internal pressure during inflation, resulting in an uneven surface that compresses the surrounding tissues and organs; moreover, the balloon wall is relatively thick, and the size after folding is relatively large, causing excessive trauma after implantation, secondary harm to the patient, and slow wound healing; the conventional balloon isolation device also has inaccurate size during inflation, which inevitably leads to an enlarged radiotherapy area and an increased impact on the surrounding healthy tissues or organs. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is: to overcome the deficiencies of the prior art and provide an expandable support isolation balloon to solve the technical problem that the height dimension of the conventional isolation balloon cannot be adjusted.

[0029] The balloon body 3 includes a top surface 31, a bottom surface 32 and a circle of side surfaces 33, one of which has a connecting hole;

[0030] A catheter 1, whose outlet end is connected to the connecting hole, and whose inlet end is provided with a liquid injection valve 2; the liquid injection valve 2 injects liquid and / or gas into the balloon body 3 through the catheter 1 to fill the balloon body 3;

[0031] The fiber filament group is arranged in the balloon body 3 , and the two ends of the fiber filament group are respectively connected to the inner wall surfaces on any two sides of the balloon body 3 .

[0032] In this embodiment, a circle of side surfaces can also be formed by directly welding the upper and lower planes.

[0033] Specifically, as an optional implementation in this embodiment, Figure 1 As shown, the top surface 31 and the bottom surface 32 of the balloon body 3 are both polygonal, and the polygon is preferably a quadrilateral, see Figure 1 shown.

[0034] Specifically, as an optional implementation in this embodiment, Figure 2 As shown, the fiber filament group is connected between the top surface 31 and the bottom surface 32.

[0035] The side surface 33 is a ring structure, and the fiber group can also be connected between the side surfaces 33.

[0036] Specifically, as an optional implementation in this embodiment, Figure 2 As shown, the uneven shapes of the ends of each fiber filament 4 in the fiber filament group define the shape of the outer wall of the balloon body 3 .

[0037] Each fiber filament 4 is long and short. After each fiber filament 4 is connected to the inner wall of the balloon, the shape of the outer wall of the balloon can be controlled by pulling the fiber filament 4 .

[0038] As Figure 2 In [reference], the lengths of the respective filaments 4 are equivalent, such that the top surface 31 and the bottom surface 32 of the isolation balloon are thereby kept flat.

[0039] In addition to controlling the shape of the outer wall of the balloon by the length of the filaments 4, the shape of the balloon can also be controlled by changing the wall thickness of the balloon.

[0040] In this embodiment, the outer wall of the balloon body 3 is one or more of a flat straight surface, a wavy structure, or a parabolic structure.

In addition, it can also assist in treatments such as occlusion, support, and ensuring position stability.

[0046] The balloon is filled through the liquid injection valve 2 to isolate the lesion from normal tissues.
