Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to a triangular balloon uterine stent capable of expanding in an umbrella-like manner. Background Art
[0002] Intrauterine adhesions (IUA), also known as Asherman's syndrome, are caused by trauma to the pregnant or non-pregnant uterus, leading to damage to the basal layer of the endometrium, partial or complete occlusion of the uterine cavity, and a series of symptoms such as menstrual abnormalities, infertility, or recurrent miscarriage. Currently, the placement of an anti-adhesion balloon is a good option for preventing intrauterine adhesions after hysteroscopic surgery. However, the use of traditional balloon uterine stents still has many inconveniences:
[0003] Existing balloon uterine stents lack structural flexibility and are difficult to adapt to the uterine morphology of different patients. They are prone to slippage or displacement during use, affecting the treatment effect. In addition, the existing triangular balloon stents are inconvenient to insert the balloon and the operation is complicated, which makes it difficult for doctors to complete the surgical operation quickly and accurately, and the use effect is not good enough.
[0004] In response to the above problems, the present utility model document proposes a triangular balloon uterine stent that can be expanded in an umbrella-like manner. Utility Model Content
[0005] The purpose of the utility model is to solve the shortcomings of the prior art, such as the easy slippage or displacement of the balloon uterine stent after being placed in the patient's uterine cavity, the complicated operation and inconvenience in use when the balloon is placed in the uterine cavity, and to propose a triangular balloon uterine stent that can be expanded in an umbrella-like manner.
[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0007] A triangular balloon uterine stent capable of expanding in an umbrella-like manner, comprising:
[0008] The balloon body is an inverted triangular balloon, one end of which is fixedly connected to an infusion tube via a joint, and the other end of which is fixedly connected to an infusion port, which is used to connect to an external water supply device and to inject physiological saline into the balloon body to cause it to expand;
[0009] It also includes a fixing clamp, which consists of two arc-shaped frames, two elastic sheets and a fixing ring. The two elastic sheets are fixedly installed on the outer wall of the fixing ring. One end of the two elastic sheets is fixedly installed on the corresponding arc-shaped frames. The two arc-shaped frames cooperate with each other. The fixing clamp is used to clamp and fix the balloon body after rolling and compression, so as to ensure that the volume of the compressed balloon body is small so as to complete the insertion of the balloon body.
[0010] In a possible design, a one-way valve is provided inside the infusion interface to ensure that the physiological saline injected into the balloon body does not leak out at will.
[0011] In a possible design, a first connecting tube is fixedly installed at one end of the fixing ring, and a second connecting tube is fixedly installed at one end of the first connecting tube. The first connecting tube is made of a hard material, and the second connecting tube is made of a deformable material. The first connecting tube and the second connecting tube are both sleeved on the outside of the infusion tube for removing the fixing clamp.
[0012] In a possible design, one end of the infusion tube extends into the balloon body through an interface, so that the balloon body can be rolled up like an umbrella with the infusion tube as the axis.
[0013] In a possible design, the diameter of the rolled balloon body is larger than the maximum diameter of the infusion tube and the infusion interface, so as to ensure the normal removal of the fixing clip.
[0014] In a possible design, the outer wall of the infusion tube is provided with a plurality of annular scales for judging the insertion length of the infusion tube.
[0015] In a possible design, the first connecting tube and the second connecting tube are both made of a transparent material to avoid affecting the observation of the multiple annular scales.
[0016] In the present application, when in use, the medical staff can roll and compress the unexpanded balloon body in an umbrella-like manner, and the infusion tube inserted into the interior of the balloon body can be used as the axis during rolling, so as to ensure that the volume of the balloon body is compressed small enough; thereafter, one end of the infusion interface can be passed through the fixing clamp and completed through the first connecting tube and the second connecting tube, and then one end of the infusion interface is pulled until the balloon body moves into the fixing clamp. At this time, the rolled and compressed balloon body will be clamped by the two movable arc frames, and the rolled and compressed balloon body can be fixed under the action of the two elastic sheets; then the medical staff can use the second connecting tube to control the balloon body to extend into the patient's uterine cavity. Since the second connecting tube has a certain deformation ability, it can cooperate with the infusion tube to complete the corresponding adjustment; when the balloon body moves to the corresponding position, the medical staff can use the infusion tube to Physiological saline is gradually injected into the interface, at which time the balloon body slowly expands and the two arc-shaped frames are gradually stretched open; due to the limitation of the shape of the balloon body, the outer diameter of the end of the balloon body away from the infusion tube is larger, and the other end is smaller. At this time, the fixing clamp will gradually slide along the inclined surface formed by the expansion of the balloon body, and finally completely detach from the outside of the balloon body; as the balloon body continues to expand, the balloon body can stretch and compress the patient's uterine cavity until the size of the balloon body is appropriate, and the medical staff can stop injecting liquid; then the user can slowly remove the fixing clamp through the second connecting tube, and the insertion of the balloon body is completed; when the balloon body needs to be removed, the user can first extract the liquid in the balloon body, and open the one-way valve in the infusion interface through the corresponding connecting joint, and then complete the removal of the balloon body according to the operating procedures of the existing technology.
[0017] Beneficial effects:
[0018] In the present invention, the umbrella-like expandable triangular balloon uterine stent adopts an inverted triangular balloon as the main structure, which is connected to the infusion port via an infusion tube to achieve expansion and contraction of the balloon. This design enables the stent to conform to the shape of the uterus when deployed, providing stable and reliable support. At the same time, the stent is retracted in a manner similar to a folding umbrella, which is easy to operate and compacts to a small enough size, making it easy for doctors to quickly insert and remove the stent.
[0019] In the utility model, the triangular balloon uterine stent capable of expanding in an umbrella-like manner is provided with a fixing clamp, which is composed of two arc-shaped frames, two elastic sheets and a fixing ring. By utilizing the elastic effect of the elastic sheets, the arc-shaped frames can tightly clamp the rolled balloon body, thereby ensuring its stability during insertion, facilitating operation, and improving the efficiency of balloon insertion.
[0020] In this utility model, the triangular balloon uterine stent innovatively adopts an inverted triangle design and a folding umbrella-like rolling mechanism, which not only improves the adaptability and stability of the stent in the uterus, but also simplifies the operation process. The application of the fixing clip ensures the stability of the balloon compression, facilitates the insertion of the balloon, and has high operation efficiency. The transparent connecting tube and scale design enhance the accuracy and convenience of the operation, and overall improve the surgical efficiency and patient satisfaction.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0027] Example 1
[0028] Reference Figure 1-4 A uterine stent includes: a balloon body 1, an infusion tube 2, an infusion interface 3 and a fixing clamp 4.
[0029] First, the balloon body 1 is designed in an inverted triangle shape, which is convenient for forming a stable support in the uterus. One end of the balloon body 1 is firmly connected to the infusion tube 2 through a joint to ensure that the connection is sealed and leak-free. The other end of the infusion tube 2 is connected to the infusion interface 3, which is designed as a standard connection structure and is convenient for connection to external water supply equipment such as a saline bag or an infusion pump. A one-way valve is provided inside the infusion interface 3 to ensure that the saline will not leak backflow when not subjected to external force. The one-way valve is the same as that in the announcement number CN212282515U, and the two-way communication of the one-way valve can be completed by connecting the corresponding connecting joints.
[0030] To facilitate the convenient carrying and insertion of the balloon body 1 when not in use, this embodiment incorporates a retaining clip 4. The retaining clip 4 comprises two curved frames 7, two elastic sheets 8, and a retaining collar 9. The two elastic sheets 8 are fixedly mounted on the outer wall of the retaining collar 9, one end of each of which is connected to the corresponding curved frame 7. This allows the two curved frames 7 to open and close relative to each other to hold the retracted balloon body 1. When the balloon body 1 is retracted and compressed like a folding umbrella, the retaining clip 4 secures it in place, maintaining its compact size and facilitating insertion into the uterus through narrow passages such as the cervical canal.
[0031] Furthermore, considering the expansion of the balloon body 1 and the automatic detachment of the retaining clip 4, this embodiment designs the infusion tube 2 into a structure that can guide the balloon body 1 to retract like an umbrella. Specifically, one end of the infusion tube 2 extends into the interior of the balloon body 1 through an interface, so that during the process of injecting physiological saline to expand the balloon body 1, the balloon body 1 can expand outward with the infusion tube 2 as the axis, forming a shape similar to an unfolded umbrella. At this time, as one end of the balloon body 1 continues to expand, and due to the shape of the balloon body 1, the outer diameter of the end of the balloon body 1 away from the infusion tube 2 is larger, and the other end is smaller. At this time, the retaining clip 4 will gradually slide along the inclined surface formed by the expansion of the balloon body 1, and eventually completely detach from the outside of the balloon body 1.
[0032] This application can be used in the field of medical equipment technology, and can also be used in other fields applicable to this application.
[0033] Example 2
[0034] refer to Figure 1 、 2 4. Improvement based on Example 1: A triangular balloon uterine stent capable of expanding in an umbrella-like manner, which is applied to the field of medical equipment technology;
[0035] In this embodiment, in order to ensure that the fixing clamp 4 can smoothly clamp the rolled-up balloon body 1 without affecting its removal, the diameter of the rolled-up balloon body 1 should be larger than the maximum diameter of the infusion tube 2 and the infusion interface 3, so that after the fixing clamp 4 is detached from the balloon body 1, it can be removed along the infusion tube 2.
[0036] To further optimize the removal of the retaining clip 4, this embodiment adds a first connecting tube 5 and a second connecting tube 6 to one end of the retaining collar 9. The first connecting tube 5 is made of a rigid material to ensure structural stability, while the second connecting tube 6 is made of a deformable material, such as medical-grade silicone or rubber, to increase its flexibility. Both connecting tubes are sleeved onto the outside of the infusion tube 2 to facilitate the removal and placement of the retaining clip 4.
[0037] To enhance ease of use, this embodiment also features multiple annular scales 10 on the outer wall of the infusion tube 2. These scales indicate the length of the infusion tube 2 extending into the balloon body 1, helping medical personnel adjust the degree of inflation of the balloon body 1 based on actual needs and achieving precise control. Furthermore, to facilitate observation, both the first and second connecting tubes 5, 6 are made of transparent material, ensuring that the annular scales 10 are not obscured during operation.
[0038] After the blister packing is in the air, the blister packing 1 is tightened, and the blister packing 1 is tightened, so that the blister packing 1 is tightened and the blister packing 1 is tightened. The staff can gradually inject normal saline through the infusion interface 3. At this time, the balloon body 1 slowly expands and the two arc-shaped frames 7 are gradually stretched open. Due to the shape limitation of the balloon body 1, the outer diameter of the end of the balloon body 1 away from the infusion tube 2 is larger, and the other end is smaller. At this time, the fixing clamp 4 will gradually slide along the inclined surface formed by the expansion of the balloon body 1, and finally completely separate from the outside of the balloon body 1. As the balloon body 1 continues to expand, the balloon body 1 can stretch and compress the patient's uterine cavity until the size of the balloon body 1 is appropriate, and the medical staff can stop injecting liquid. After that, the user can slowly remove the fixing clamp 4 through the second connecting tube 6, and the insertion of the balloon body 1 is completed. When the balloon body 1 needs to be removed, the user can first extract the liquid in the balloon body 1, and the one-way valve in the infusion interface 3 can be opened through the corresponding connecting joint. Then, the balloon body 1 can be removed according to the operating procedures of the prior art.
[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
