Description

Technical Field

[0001] The present invention relates to the technical field of vertebral expansion, and in particular to a vertebral expansion balloon catheter system. Background Art

[0002] The vertebral expansion balloon catheter is a tool needed during surgery to help the vertebrae with compression fractures return to their normal shape. During the specific operation, the doctor places the balloon catheter into the damaged vertebra and uses the inflation and expansion function of the balloon to effectively expand the fracture site and restore the height of the vertebra.

[0003] Patent announcement number CN217960969U discloses a vertebral dilatation balloon catheter, comprising a Y-shaped tube, a catheter is provided inside the Y-shaped tube, a guide wire is inserted inside the catheter, a wire handle and a needle are installed at both ends of the guide wire, a vesicle is installed at the end of the catheter away from the wire handle, an angiography ring is symmetrically installed inside the vesicle, a bump is installed at the interface of the Y-shaped tube, a rotating shaft is installed inside the bump, a circular plate is provided on the outer surface of the rotating shaft, a convex plate is installed on the top of the circular plate, and the convex plate is sleeved on the outer surface of the rotating shaft. The utility model, by providing the bump, rotating shaft, circular plate and related structures such as the convex plate, can seal and shield the interface of the Y-shaped tube before the Y-shaped tube is used through the bonding action of the circular plate, thereby preventing the Y-shaped tube interface from being directly exposed to the air, making the subsequent use of the Y-shaped tube interface more hygienic, while having a simple structure and easy operation.

[0004] During use, the above device can isolate the interface of the Y-type tube to prevent it from being contaminated. However, in actual application, the damaged part of the vertebra needs to be expanded and propped up by balloon expansion, so the balloon is the core component of the entire vertebral expansion work. The above device is similar to the existing structure and does not have the function of detecting the integrity of the balloon. In actual application, if the balloon is damaged to a large extent, it is easier for the staff to check it out. Once the damaged part is relatively small, that is, the small leakage in the inflated state is not easy to be detected by outsiders, once it is inserted into the affected area for inflation and expansion, the strength of the balloon expansion will not be equal to the injected pressure, which will directly affect the quality of the operation. Secondly, the leaked gas will also cause damage in the patient's body. Therefore, a vertebral expansion balloon catheter system is proposed to solve the above problems. Summary of the Invention

[0036] The following is combined with Figure 1 -Attached Figure 8 The present invention is described in further detail.

[0037] The present invention discloses a vertebral dilatation balloon catheter system, comprising a pressure pump body 1, a connecting tube 2, and a catheter 3. A Y-shaped tube 7 is integrally formed at one end of the catheter 3. A balloon 4 is fixedly connected to the outside of the catheter 3. A discharge port 5 is formed on the catheter 3 and disposed inside the balloon 4. A detection mechanism 6 is disposed on the pressure pump body 1.

[0038] The detection mechanism 6 includes a transparent detection box 61, which is arranged on one side of the pressure pump body 1. The two sides of the pressure pump body 1 are respectively fixedly connected with a socket 62 and an auxiliary frame 63. The transparent detection box 61 is fixedly connected with a plug plate 64, which extends into the interior of the socket 62 and matches the socket 62. A movable plug 65 is provided inside the auxiliary frame 63, and the movable plug 65 contacts the inner cavity wall of the auxiliary frame 63. A push rod 66 is fixedly connected to the movable plug 65, and the push rod 66 extends out of the auxiliary frame 63. A control box 67 is provided on the top of the pressure pump body 1. The bottom of the control box 67 is fixedly connected to the first interface 68, and the top of the control box 67 is fixedly connected to the second interface 69. A third interface 692 is integrally formed at one end of the Y-shaped tube 7. The top of the pressure pump body 1 extends into the interior of the first interface 68 and is connected to the first interface 68 through a threaded connection;

[0039] Both ends of the connecting tube 2 are fixedly connected with connectors 691, and the two connectors 691 extend into the second interface 69 and the third interface 692 respectively. The two connectors 691 match the second interface 69 and the third interface 692 respectively. A connecting tube 693 is fixedly connected to the top of the auxiliary frame 63, and one end of the connecting tube 693 is fixedly connected to one side of the control box 67. The transparent detection box 61 is filled with a transparent liquid such as alcohol or pure water. Before performing vertebral expansion, the balloon 4 can be inserted into the transparent detection box 61 and the push rod 66 is pressed. The push rod 66 drives the movable plug 65 to move and push the gas into the balloon 4, causing the balloon 4 to swell. At this time, since the balloon 4 is immersed in the transparent detection box 61, if the balloon 4 is damaged and leaks, the gas leakage will cause bubbles to be generated in the transparent detection box 61. In this way, the integrity of the balloon 4 can be quickly tested before the operation. The detection process is intuitive and convenient, which improves the safety of the operation.

[0040] A first trapezoidal sealing block 694 and a second trapezoidal sealing block 695 are slidably connected to the interior of the control box 67. The first trapezoidal sealing block 694 fits against the bottom wall of the inner cavity of the control box 67, and the second trapezoidal sealing block 695 fits against a side wall of the inner cavity of the control box 67. A limiting telescopic rod 696 is fixedly connected to the top wall of the control box 67. A first spring 697 is fixedly connected to the top wall of the inner cavity of the control box 67. The limiting telescopic rod 696 passes through the first spring 697. A threaded rod 698 is rotatably connected to the interior of the control box 67. The threaded rod 698 extends out of the outside of the control box 67. The first trapezoidal sealing block 694 seals the bottom wall of the control box 67, and the second trapezoidal sealing block 695 seals a side wall of the control box 67 connected to the connecting pipe 693.

[0041] The threaded rod 698 passes through the first trapezoidal sealing block 694 and is connected to the first trapezoidal sealing block 694 through a threaded connection. The limiting telescopic rod 696 and one end of the first spring 697 are fixedly connected to the top of the second trapezoidal sealing block 695. The first trapezoidal sealing block 694 fits with the second trapezoidal sealing block 695. After the threaded rod 698 rotates, it drives the first trapezoidal sealing block 694 to move horizontally. The bottom of the movable plug 65 is fixedly connected to the second spring 699. One end of the second spring 699 is fixedly connected to the bottom wall of the inner cavity of the auxiliary frame 63. The push rod 66 passes through the second spring 699. The second spring 699 exerts an elastic force on the movable plug 65.

[0042] The outside of the connector 691 is integrally formed with anti-slip stripes 681, and the inside of the second interface 69 and the third interface 692 are both provided with anti-slip grooves 682. The anti-slip stripes 681 extend into the inside of the anti-slip grooves 682 and match the anti-slip grooves 682. After the anti-slip stripes 681 enter the inside of the anti-slip grooves 682, the tightness of the connection between the connector 691 and the second interface 69 and the third interface 692 can be improved. A card slot 683 is provided at the bottom of the socket 62. A trapezoidal card block 684 is slidably connected to the inside of the plug plate 64. The trapezoidal card block 684 extends out of the outside of the plug plate 64. The trapezoidal card block 684 passes through the card slot 683 and matches the card slot 683. A spring 685 is fixedly connected to the inside of the plug plate 64. The spring 685 is fixedly connected to one side of the trapezoidal card block 684, and the spring 685 exerts an elastic force on the trapezoidal card block 684.

[0043] Four suction cups 686 are provided at the bottom of the transparent detection box 61. The four suction cups 686 are respectively fixedly connected to the four corners of the bottom of the transparent detection box 61. The suction cups 686 can adhere to the placement surface when the transparent detection box 61 is in use, thereby improving the stability of the transparent detection box 61. A sealing cover 687 is provided on the top of the transparent detection box 61. The transparent detection box 61 extends into the interior of the sealing cover 687 and is connected to the sealing cover 687 through threads. The sealing cover 687 covers and seals the transparent detection box 61.

[0044] During actual operation, the gas or liquid used to expand the balloon 4 is sucked into the pressure pump body 1, the control box 67 is screwed and tightened onto the connecting end of the pressure pump body 1, and then the two connectors 691 are respectively inserted into the second interface 69 and the third interface 692 to complete the installation of the connecting tube 2. When in use, the gas or liquid inside the pressure pump body 1 is pushed out, and the gas or liquid enters the catheter 3 and enters the balloon 4 through the discharge port 5 on the catheter 3, causing the balloon 4 to inflate;

[0045] The shell of the transparent detection box 61 is made of transparent material. At the same time, the inside of the transparent detection box 61 can be injected with non-polluting transparent liquid such as alcohol or pure water, which is convenient for the user to observe the internal situation. Before the above balloon 4 performs the expansion task, the integrity of the balloon 4 is first tested. During the specific test, the trapezoidal block 684 is squeezed to enter the inside of the plug plate 64, and the plug plate 64 can be pulled out from the socket 62 to remove the transparent detection box 61 for use. When in use, the suction cup 686 at the bottom is conducive to the transparent detection box 61 sucking on the placement platform. Attached with use, thereby improving the stability during the detection process. Similarly, during installation, directly align the plug plate 64 with the socket 62 and insert it. Under the elastic force of the reed 685, the trapezoidal block 684 is pushed out and passes through the card slot 683, and then the transparent detection box 61 can be installed. The installation process is simple and convenient. It can be carried together with the pressure pump body 1, and the balloon 4 detection work can be carried out at any time. During the specific detection, the sealing cover 687 is rotated and unscrewed, and the control catheter 3 is inserted into the transparent detection box 61 until the balloon 4 is submerged in water to carry out the detection work;

[0046] The first trapezoidal sealing block 694 seals the bottom wall of the control box 67, and the second trapezoidal sealing block 695 seals the side wall of the control box 67 connected to the connecting pipe 693. The threaded rod 698 is rotated, and the threaded rod 698 drives the first trapezoidal sealing block 694. When the first trapezoidal sealing block 694 moves toward the second trapezoidal sealing block 695, its inclined surface contacts the inclined surface of the second trapezoidal sealing block 695, which will form an effect of pushing the second trapezoidal sealing block 695 upward. When the first trapezoidal sealing block 694 moves away from the second trapezoidal sealing block 695, due to gravity and the elastic force of the first spring 697, The second trapezoidal sealing block 695 will be pushed downward. When the detection work is carried out, the threaded rod 698 is rotated to control the first trapezoidal sealing block 694 to move to the top of the first interface 68 to seal the first interface 68. At this time, the second trapezoidal sealing block 695 moves to the bottom of the opening on the side wall where the control box 67 and the connecting pipe 693 are connected. The push rod 66 is pressed, and the push rod 66 drives the movable plug 65 to move, which can push the gas in the auxiliary frame 63 into the catheter 3 and into the balloon 4 through the discharge port 5. If the balloon 4 is damaged, bubbles will be formed in the liquid and discharged. The user can quickly judge based on the presence or absence of bubbles.

[0047] If no bubbles are generated after the above test, it means that the balloon 4 is intact. At this time, stop pressing the push rod 66, and the second spring 699 pulls the movable plug 65 back. It can be seen from the above operation that the gas entering the balloon 4 is sucked out, and the balloon 4 returns to its initial state. After the balloon 4 is taken out, it can be used for surgical expansion. During the operation, the threaded rod 698 is rotated to control the first trapezoidal sealing block 694 to move to the top side of the first interface 68. At this time, the second trapezoidal sealing block 695 is squeezed and moved to the second trapezoidal sealing block 695. The control box 67 and the connecting pipe 69 are connected. 3 is sealed and blocked, at this time the pressure pump body 1 can be controlled to send the gas or liquid in the pressure pump body 1 into the balloon 4 for expansion. The advantage of the above-mentioned method of adding the auxiliary frame 63 and using the first trapezoidal sealing block 694 and the second trapezoidal sealing block 695 to perform separate control of the channel sealing is that the integrity of the balloon 4 can be quickly tested, and based on the test, it will not interfere with the use of the pressure pump body 1 that needs to absorb liquid substances for filling and expansion, and the operation is simple, which is conducive to quick operation.

[0048] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
