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 by implanting a folded pressure balloon is available. The folded pressure balloon includes 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 the surgery, the balloon body, folded into a strip shape, is first 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 causes the balloon body to expand and press against the retina to perform the treatment.

[0004] Currently, doctors typically fold the balloon into a strip during surgery. This folding requires precise clamping and folding, and doctors need extensive professional training before the operation. During the operation, doctors must wear sterile gloves to fold the balloon, which is difficult and can easily lead to poor folding results. Utility Model Content

[0005] The technical problem to be solved by this invention is to provide a foldable pressure balloon that facilitates surgical procedures for doctors.

[0006] To solve the above-mentioned technical problems, this utility model provides a foldable top-pressure balloon, including a balloon body and a drainage component. The balloon body is hollow inside to form a balloon cavity for containing filling medium. The drainage component is connected to the balloon body and communicates with the balloon cavity. The balloon body is folded into a strip shape around the axis of the drainage component. The folded balloon body is tied with a strap to maintain the balloon body in a strip shape.

[0007] Furthermore, after the balloon body contains the filling medium, it includes a first surface that is planar and a second surface that is curved, and the drainage component is specifically connected to the junction of the first surface and the second surface of the balloon body.

[0008] Furthermore, the balloon body, after containing the filling medium, is shaped like a spherical crown, with its first surface being the bottom surface of the crown and its second surface being the arc surface of the crown.

[0009] Furthermore, a fixing loop is provided at the junction of the first surface and the second surface for the suture to pass through and fix the balloon body after it contains the filling medium.

[0010] Furthermore, the fixing loop and the drainage component are respectively located at the two diagonal ends of the balloon body after it has received the filling medium.

[0011] Furthermore, the junction between the first surface and the second surface is smoothly transitioned.

[0012] 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.

[0013] Furthermore, the axis of the drainage component specifically passes through the central axis of the drainage valve and the core of the drainage tube.

[0014] This invention has the following advantages: the balloon body of the foldable pressure balloon is folded into a strip shape around the axis of the drainage component, and a strap is tied around the outside of the folded balloon body to maintain the strip shape. In this way, when using the foldable pressure balloon in surgery, the doctor only needs to hold the balloon body and cut the strap to obtain the strip-shaped balloon body and implant it into the eye. The doctor does not need to wear sterile gloves at the surgical site to fold the balloon body into a strip shape, which facilitates the doctor's surgical operation. Attached Figure Description

[0017] The present invention will be further described in detail below with reference to specific embodiments.

[0018] This embodiment provides a foldable pressure balloon, which, before folding, is as follows: Figure 2As shown, the device includes a balloon body 1 and a drainage component 2 connected to each other. The balloon body 1 includes a planar first surface 11 and a curved second surface 12, with a smooth transition at the junction of the first surface 11 and the second surface 12. 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 junction of the first surface 11 and the second surface 12 of the balloon body 1 through the drainage tube 22 and communicates with the balloon cavity. After the filling medium is injected into the balloon cavity inside the balloon body 1 through the drainage component 2, the balloon body 1 is filled into a spherical shape, with its first surface 11 being the bottom surface of the spherical crown and its second surface 12 being the arc surface of the spherical crown. A fixing haptic 4 is provided at the junction of the first surface 11 and the second surface 12 of the balloon body 1. The fixing haptic 4 and the drainage component 2 are respectively located at the two ends of the diagonal line after the balloon body 1 contains the filling medium.

[0019] In this embodiment, the balloon body 1 is made of soft medical-grade silicone and is foldable and deformable. The folded balloon body 1, when folded to compress the balloon, is as follows: Figure 1 As shown, the balloon body 1 is folded into a strip shape around the axis of the drainage component 2. The axis of the drainage component 2 specifically passes through the central axis of the drainage valve 21 and the core of the drainage tube 22. The folded strip-shaped balloon body 1, together with the drainage tube 22 and the drainage valve 21, forms a long strip. The outer side of the folded balloon body 1 is tied with a strap 3 to maintain the balloon body 1 in a strip shape.

[0020] During the surgery, when using a folded balloon 1 folded into a strip shape for pressure, the doctor only needs to hold the balloon 1 with forceps and then cut the strap 3 with scissors to obtain the strip-shaped balloon 1. This eliminates the need for the doctor to wear sterile gloves during the surgery, making the procedure easier. The doctor then implants the balloon 1 into the eye and inserts a syringe filled with a filling medium (such as saline, air, silicone oil, gel, etc.) into the drainage valve 21 of the drainage component 2. The filling medium is injected into the balloon cavity of the balloon 1 through the drainage valve 21 and drainage tube 22, causing the balloon 1 to inflate into a crown shape. Sutures are then passed through the fixation haptic 4 to fix the balloon 1, now filled with the filling medium, inside the eye, preventing movement and avoiding complications caused by balloon 1 movement. This ensures that the balloon 1 effectively presses against the retina for treatment.

[0021] 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.
