Description

Technical Field

[0001] This utility model relates to the field of medical technology, and in particular to a device for sealing intestinal fistulas. Background Technology

[0002] An enterocutaneous fistula is an abnormal passage between the intestine and other organs, body cavities, or the body surface, through which intestinal contents leak out. Enterocutaneous fistulas can lead to a series of serious complications, including loss of digestive fluids, infection, and malnutrition, severely impacting a patient's health and quality of life. Currently, clinical treatments for enterocutaneous fistulas include conservative and surgical methods. However, conservative treatment has limited effectiveness, while surgical treatment is highly invasive, carries significant risks, and has a long recovery time. Existing enterocutaneous fistula closure devices have some shortcomings, such as poor adaptability to fistulas of different shapes and sizes. Therefore, a novel enterocutaneous fistula closure device is needed to address these issues. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fistula sealing device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An intestinal fistula sealing device includes an air bladder with an air injection port, a plate at the air injection port, and a through-hole at the plate. The air injection port penetrates the inner wall of the through-hole and is fixedly connected.

[0006] Preferably, the sheet body has multiple sets of through slots.

[0007] Preferably, one end of the inner wall of the airbag is connected to an elastic cord, and a ball is connected between the two sets of elastic cords. The ball is connected to the air injection port.

[0008] Preferably, the air bladder is a spherical structure.

[0009] Preferably, the outer wall of the airbag is processed with multiple sets of annular grinding textures.

[0010] Preferably, the airbag is connected to a ring.

[0011] Preferably, the elastic rope and the ball constitute a one-way valve assembly.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. By coordinating the airbag, air inlet, sheet, through groove, and through opening, the air inlet is connected to an external air pump to inflate the airbag. Then, when the entire assembly is pulled to the intestinal fistula, the airbag, made of medical-grade silicone, can adaptively seal the fistula to a certain extent according to the different shapes and sizes of the fistula, ensuring the sealing effect and reducing leakage of intestinal contents.

[0014] 2. By coordinating the piece and the slot, after the airbag blocks the enterocutaneous fistula, the slot on the piece can be threaded through the suture and sewn to one end of the fistula to enhance its placement stability and ensure the stability of the blockage.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1, referring to Figures 1 to 5The enterocutaneous fistula closure device includes an airbag 1 made of medical-grade silicone, which has good biocompatibility and flexibility. An air injection port 2 is located at the air injection port 2, and a sheet 3 is located at the sheet 3. An opening 5 is located at the sheet 3, and the air injection port 2 penetrates the inner wall of the opening 5 and is fixedly connected. The good flexibility allows the airbag 1 to deform according to the actual shape and size of the enterocutaneous fistula channel. Enterocutaneous fistula channels are not regular shapes, and each patient's situation is different. The flexibility of the airbag 1 allows it to closely conform to various irregular enterocutaneous fistula channels after inflation, achieving seamless closure, effectively preventing intestinal contents from leaking out through the fistula opening, greatly improving the closure effect, and aiding in the patient's recovery.

[0023] In this embodiment, multiple sets of through grooves 4 are provided at the sheet 3. After the airbag 1 blocks the enterocutaneous fistula channel, the through grooves 4 can be used to pass through the suture. Medical staff can pass one end of the suture through the through groove 4 and then sew it to one end of the enterocutaneous fistula channel. This method further enhances the stability of the device within the enterocutaneous fistula channel and prevents the airbag 1 from shifting due to intestinal peristalsis or other factors, thereby ensuring the long-term stability of the blockage. One end of the inner wall of the airbag 1 is connected to an elastic rope 7, and a ball 6 is connected between the two sets of elastic ropes 7. When gas is injected into the airbag 1 through the air injection port 2 using an external air pump, the pressure generated by the gas will push the ball 6 open, allowing the gas to smoothly enter the airbag 1 and realize the inflation process. After inflation, the sphere 6 quickly returns to its original position under the elastic force of the elastic rope 7, resealing the air injection port 2 and effectively preventing gas leakage from the airbag 1. The airbag 1 has a spherical structure, which allows it to expand evenly in all directions after inflation, better conforming to the irregular shape of the enterocutaneous fistula channel and achieving a tight seal. This choice of material and shape not only effectively reduces leakage of intestinal contents but also reduces irritation to intestinal tissue, improving patient comfort and safety. The outer wall of the airbag 1 is machined with multiple sets of annular grooves 8, which greatly increase the friction between the airbag 1 and the inner wall of the enterocutaneous fistula channel. When the airbag 1 seals the enterocutaneous fistula channel, the grooves 8 prevent the airbag 1 from sliding in the intestine, further improving the sealing stability of the device. At the same time, the grooves 8 can also increase the contact area between the airbag 1 and the intestinal tissue to a certain extent, making the seal tighter and reducing the risk of leakage of intestinal contents. A ring 9 is connected to the airbag 1, which can be connected to the traction workpiece during the placement of the device into the enterocutaneous fistula channel. With the help of traction tools, medical staff can move the device into the enterocutaneous fistula channel more accurately and conveniently, improving the accuracy and efficiency of the operation. The elastic rope 7 and the ball 6 constitute a one-way valve assembly.

[0024] All of the above structures are made of medical-grade materials. The materials are selected according to actual needs. For example, the elastic rope 7 can be made of medical-grade latex filament, the ball 6 can be made of silicone rubber, and the sheet 3 can be made of polycarbonate, etc.

[0025] The working principle of this embodiment is as follows: When in use, according to the actual size of the intestinal fistula channel, gas is first injected into the air injection port 2 using an external air pump. The gas will reopen the ball 6 blocking the air injection port 2, so the airbag 1 will be inflated. After inflation, due to the elasticity of the elastic rope 7, the ball 6 can re-seal the air injection port 2 to prevent air leakage. After inflation, the traction workpiece is connected to the ring 9 and moved into the intestinal fistula channel with the help of the traction tool to seal the intestinal fistula channel. At the same time, the through groove 4 of the piece 3 at one end of the intestinal fistula channel can be sewn to the intestinal wall with thread to fix the piece 3, ensuring that the airbag 1 is placed stably in the intestinal fistula channel.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
