Description

Technical Field

[0001] This utility model relates to the field of ophthalmic medical device technology, and in particular to a foldable top-pressure balloon. Background Technology

[0002] Retinal detachment is a relatively common eye disease that can lead to decreased vision and even blindness. The traditional treatment for retinal detachment involves scleral buckling to encircle and apply pressure to the eyeball. However, traditional scleral buckling has drawbacks such as large surgical incisions and a high risk of infection.

[0003] A method for treating retinal detachment involves implanting a foldable pressure balloon. The balloon comprises a balloon body and a drainage component. The balloon body is hollow, and the drainage component connects to the interior of the balloon body. During surgery, the balloon body is first folded into a strip and implanted into the eye. Then, a filling medium, such as saline, air, silicone oil, or gel, is injected into the balloon body through the drainage component. This inflates the balloon, causing it to press against the retina for treatment. Because the balloon body is folded during implantation, the surgical incision is small, and the wound is less prone to infection. However, the balloon body, after inflating, becomes approximately spherical, which can easily shift within the eye, resulting in ineffective pressure on the retina. Utility Model Content

[0004] The technical problem to be solved by this invention is to provide a foldable top-pressure balloon that is not easily displaced.

[0005] To solve the above-mentioned technical problems, this utility model provides a foldable top-pressure balloon with a frosted surface, including a balloon body and a drainage component. The balloon body is hollow inside to form a balloon cavity for containing filling media. The drainage component is connected to the balloon body and communicates with the balloon cavity. The outer surface of the balloon body is frosted.

[0006] Furthermore, the balloon body includes a planar first surface and a curved second surface, and the drainage component is specifically connected to the second surface of the balloon body.

[0007] Furthermore, the balloon body is spherical, with its first surface being the bottom surface of the spherical crown and its second surface being the arc surface of the spherical crown.

[0008] Furthermore, the diameter of the spherical capsule is 13 mm, and the distance from the vertex of the first surface to the second surface is 10 mm.

[0009] Furthermore, the diameter of the spherical capsule is 10.4 mm, and the distance from the vertex of the first surface to the second surface is 8 mm.

[0010] Furthermore, the drainage component includes a drainage valve and a drainage tube, wherein the drainage valve is connected to the balloon body and communicates with the balloon cavity through the drainage tube.

[0011] Furthermore, the width and thickness of the drainage valve are both greater than those of the drainage tube.

[0012] Furthermore, the drainage valve has a width of 2.1 mm and a thickness of 1.6 mm, and the drainage tube has a width and thickness of 1.2 mm.

[0013] Furthermore, the length of the drainage valve is shorter than that of the drainage tube.

[0014] Furthermore, the length of the drainage valve is 4mm, and the length of the drainage tube is 6mm.

[0015] The present invention has the following beneficial effects: When using the folding pressure balloon, the balloon body is folded into a strip and then implanted into the eye. Then, the filling medium is injected into the balloon cavity through the drainage component, so that the balloon body can expand and press against the retina of the eyeball. Since the outer surface of the balloon body is a frosted surface, it can increase the friction between the balloon body and the eyeball, making the balloon body less likely to shift in the eyeball, and can effectively press against the retina of the eyeball for treatment.

[0019] The present invention will be further described in detail below with reference to specific embodiments.

[0020] Example 1

[0021] This embodiment provides a folded top-pressure balloon with a frosted surface, such as Figure 1 As shown, the foldable compression balloon includes a balloon body 1 and a drainage component 2 connected to each other. The balloon body 1 is spherical, comprising a planar first surface 11 and a curved second surface 12; that is, the first surface 11 is the bottom surface of the spherical crown, and the second surface 12 is the arc surface of the spherical crown. The balloon body 1 is hollow inside, forming a balloon cavity for containing the filling medium. The drainage component 2 is connected to the balloon body 1 and communicates with the balloon cavity. Specifically, the drainage component includes a drainage valve 21 and a drainage tube 22. The drainage valve 21 is hollow inside, forming a cavity structure. The cavity structure of the drainage valve 21 is connected to the second surface 12 of the balloon body 1 and communicates with the balloon cavity through the drainage tube 22. The balloon body 1 is made of soft medical-grade silicone and is foldable and deformable.

[0022] In this embodiment, the outer surface of the balloon body 1 is a frosted surface. Specifically, one of the following three mold processing methods is used to form a frosted surface on the outer surface of the balloon body 1 obtained by mold forming in order to increase friction:

[0023] 1. Spark pattern. Through the electro-erosion effect of pulsed discharge between the tool electrode and the workpiece electrode, a rough texture is formed on the surface of the mold, thereby achieving the effect of a rough, frosted surface on the surface of the spherical body 1 formed by using the mold.

[0024] 2. Sandblasting. Sandblasting the mold roughens its surface, thereby achieving the effect of creating a frosted surface on the surface of the spherical body 1 formed using the mold.

[0025] 3. Textured surface. Through the interaction between chemical solutions and mold material, certain textured patterns are created on the mold surface, thereby achieving a rough, frosted surface effect on the spherical body 1 formed using this mold.

[0026] like Figure 2 As shown, the diameter of the balloon body 1 of the folded compression balloon is 13 mm, and the distance from the apex of the first surface 11 to the second surface 12 (i.e., the height of the balloon cap) is 10 mm. The width and thickness of the drainage valve 21 are greater than those of the drainage tube 22. Specifically, the width of the drainage valve 21 is 2.1 mm and the thickness is 1.6 mm, while the width and thickness of the drainage tube 22 are both 1.2 mm. The length of the drainage valve 21 is less than that of the drainage tube 22. Specifically, the length of the drainage valve 21 is 4 mm, and the length of the drainage tube 22 is 6 mm.

[0027] When using a foldable pressure balloon during surgery, the balloon body 1 is folded into a strip and implanted into the eye. Then, a needle filled with a filling medium (such as saline, air, silicone oil, gel, etc.) is inserted into the drainage valve 21 of the drainage component 2. The filling medium is injected into the balloon cavity of the balloon body 1 through the drainage valve 21 and drainage tube 22 of the drainage component 2, so that the balloon body 1 can expand into a spherical shape to press against the retina of the eyeball. Since the outer surface of the balloon body 1 is frosted, it can increase the friction between the balloon body 1 and the eyeball, making the balloon body 1 less likely to shift in the eye and able to effectively press against the retina of the eyeball for treatment.

[0028] Example 2

[0029] In this embodiment, the size of the balloon body 1 of the folded compression balloon differs from that in Embodiment 1, but other aspects are the same as in Embodiment 1, as detailed below. Figure 3 As shown, the diameter of the spherical body 1 is 10.4 mm, and the distance between the apex of the first surface 11 and the second surface 12 (i.e., the height of the spherical cap) is 8 mm.

[0030] The above description is merely an embodiment of the present invention and does not limit the scope of patent protection. Any non-substantial changes or substitutions made by those skilled in the art based on the present invention will still fall within the scope of patent protection.
