Description

Technical Field

[0001] This utility model relates to the field of balloon catheter technology, and in particular to a balloon catheter with high support performance. Background Technology

[0002] A balloon catheter is a flexible catheter used to widen narrow openings or passages within the body during catheterization procedures. The process involves placing a deflated balloon catheter, inflating it to perform the necessary procedures, and then deflating it again for removal. A balloon catheter typically consists of an inner tube, an outer tube, a balloon, and a catheter hub. To facilitate manipulation during surgery, balloon catheters are usually used in conjunction with a guidewire; therefore, a guidewire port is provided at the balloon catheter location.

[0003] For example, Chinese Patent No. CN221751965U discloses a balloon catheter, including an inner tube, an outer tube, and a balloon unit. The outer tube includes a first outer tube and a second outer tube fixedly connected to the first outer tube. A guidewire opening is formed at the interface where the first outer tube and the second outer tube are fixedly connected. The first outer tube includes a first extension, and the second outer tube includes a second extension. The length of the first extension is greater than that of the second extension. The guidewire opening is formed after the first extension and the second extension are fixedly connected.

[0004] Although the above technical solutions have solved the corresponding technical problems, they still have the following drawbacks:

[0005] The balloon in the above-mentioned technical solution does not provide sufficient support for the blood vessel, which may cause the blood vessel to continue to constrict after the operation, returning to the original narrow state, or even further aggravating the original narrowing or blockage, affecting the surgical outcome and the patient's treatment effect. Utility Model Content

[0013] The aforementioned balloon catheter with high support performance includes a limiting telescopic component comprising a sliding component. One end of the sliding component is rotatably connected to the side of the support plate via a first connecting lug, and the other end of the sliding component is rotatably connected to the outer tube via a second connecting lug.

[0014] The aforementioned balloon catheter with high support performance includes a sliding assembly comprising a sliding shell connected to the first connecting lug, a sliding rod slidably connected to the inner wall of the sliding shell, and the end of the sliding rod being connected to the second connecting lug.

[0015] In the aforementioned balloon catheter with high support performance, a limiting slider is fixedly connected to the end of the slide rod away from the second connecting lug, a limiting groove matching the limiting slider is provided on the inner wall of the slide shell, and a limiting ball is also installed on the limiting slider that is tactilely connected to the limiting groove.

[0039] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0040] Please refer to Figures 1 to 8 As shown, an embodiment of the present invention provides a balloon catheter with high support performance, comprising: a corrugated tube 1 and an outer tube 2 disposed at the end of the corrugated tube 1. An elastic balloon 3 that can be stably supported is installed on the outer tube 2. A catheter seat 4 is installed at the end of the corrugated tube 1 away from the outer tube 2. A guide wire body 5 is inserted into the catheter seat 4. Two contrast rings 6 are also installed on the outer tube 2 at the position corresponding to the elastic balloon 3.

[0041] By adopting the above technical solution, the balloon can provide stable support, thereby ensuring stable support for the patient's affected area. This not only improves the stability and success rate of the surgery, but also reduces the patient's risk and pain, thus improving the therapeutic effect of the surgery.

[0042] Please refer to Figures 1 to 8 As shown, the elastic balloon 3 has a support mechanism 301 inside for supporting the elastic balloon 3, and an elastic airbag 302 is sleeved on the outer tube 2 at the position corresponding to the support mechanism 301.

[0043] The outer tube 2 has a connecting port 3022 at the position corresponding to the elastic airbag 302. The elastic airbag 302 has an air inlet 3021 at the position corresponding to the connecting port 3022, which is connected to the connecting port 3022. Gas is introduced through the outer tube 2, which can cause the elastic airbag 302 to expand, thereby supporting the support mechanism 301 and increasing the overall stability of the elastic airbag 3.

[0044] Please refer to Figures 1 to 8As shown, the support mechanism 301 includes a force-bearing plate 3011 that abuts against the elastic airbag 302. A support plate 3013 is fixedly connected to the force-bearing plate 3011 via a connecting rod 3012. Limiting telescopic components 3014 are installed on both sides of the support plate 3013.

[0045] The limiting telescopic component 3014 includes a sliding component 30143. One end of the sliding component 30143 is rotatably connected to the side of the support plate 3013 via a first connecting lug 30141, and the other end of the sliding component 30143 is rotatably connected to the outer tube 2 via a second connecting lug 30142. When the elastic airbag 302 compresses the force plate 3011, it can lift the support plate 3013 and support the inner wall of the elastic balloon 3, thereby ensuring the stability of the elastic balloon 3.

[0046] Please refer to Figures 1 to 8 As shown, the sliding assembly 30143 includes a sliding shell 30144 connected to the first connecting lug 30141. A sliding rod 30145 is slidably connected to the inner wall of the sliding shell 30144, and the end of the sliding rod 30145 is connected to the second connecting lug 30142. The sliding rod 30145 slides on the inner wall of the sliding shell 30144, which increases the stability of the support plate 3013.

[0047] Please refer to Figures 1 to 8 As shown, a limiting slider 30146 is fixedly connected to the end of the slide rod 30145 away from the second connecting lug 30142. A limiting groove 30147 matching the limiting slider 30146 is provided on the inner wall of the slide shell 30144. A limiting ball 30148 that is tactilely connected to the limiting groove 30147 is also installed on the limiting slider 30146. By setting the limiting slider 30146, the limiting groove 30147 and the limiting ball 30148, the slide rod 30145 is limited, thereby increasing the sliding stability of the slide rod 30145.

[0048] Please refer to Figures 1 to 8 As shown, a protective pad 30131 is fixedly connected to the support plate 3013, and the protective pad 30131 provides protection for the elastic balloon 3.

[0049] Please refer to Figures 1 to 8 As shown, the end of the catheter seat 4 is provided with a guide wire inlet 401, and an air inlet pipe 402 is also installed on the catheter seat 4. The guide wire inlet 401 facilitates the insertion of the guide wire body 5, and the air inlet pipe 402 facilitates the introduction of gas.

[0050] Please refer to Figures 1 to 8As shown, a guide wire opening 501 is provided at the end of the outer tube 2 and at the position corresponding to the guide wire body 5. A sealing ring 5011 is provided on the inner wall of the outer tube 2 and at the position corresponding to the guide wire opening 501. The sealing performance between the guide wire body 5 and the outer tube 2 is increased by providing the sealing ring 5011.

[0051] The working principle of this utility model is as follows: while gas is introduced through the air inlet pipe 402, the elastic airbag 302 is expanded through the connecting port 3022 on the outer pipe 2, which can support the force plate 3011. Therefore, under the sliding action of the slide rod 30145 on the inner wall of the sliding shell 30144, the stability of the support plate 3013 is increased, thereby increasing the overall stability of the elastic balloon 3 and providing stable support for the balloon, thus ensuring stable support for the patient's affected area. Therefore, it not only improves the stability and success rate of the operation, but also reduces the patient's risk and pain, thereby improving the treatment effect of the operation.
