Description

Technical Field

[0001] This invention relates to the field of balloon catheter detection technology, specifically a trigeminal nerve balloon catheter detection device. Background Technology

[0002] One of the classic treatments for trigeminal neuralgia is balloon compression, which works by physically compressing the trigeminal ganglion with a balloon catheter. Trigeminal neuralgia is mainly caused by blood vessels compressing the nerve.

[0003] In practice, balloon compression surgery requires percutaneous insertion of a balloon catheter, which is then placed under X-ray or CT guidance at the location of the trigeminal ganglion. The balloon is then inflated to displace the blood vessel compressing the nerve. (See attached...) Figure 1 As shown, when balloon X inflates, it is subjected to the reaction force of blood vessels. The pressure G is concentrated in the concave areas on the balloon surface, which makes it prone to rupture. Furthermore, due to the irregular deformation of the balloon and the uneven distribution of the concave areas, the uniformity of the balloon material surface is important to ensure the normal operation of the balloon. Most existing balloon testing equipment performs puncture tests at fixed positions on the balloon surface, making it difficult to confirm the uniformity of the balloon material. Summary of the Invention

[0004] The purpose of this invention is to provide a trigeminal nerve balloon catheter detection device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a trigeminal nerve balloon catheter detection device, comprising a base, and further comprising: a detection cylinder, fixedly installed on the top of the base, and configured as having a small diameter at both ends and a large diameter in the middle; a detection unit, disposed inside the detection cylinder and used to apply compressive force to the inflated balloon; and a drive unit, disposed outside the detection cylinder and used to drive the detection unit to move in a spiral path inside the detection cylinder.

[0006] As a further embodiment of the present invention, the detection unit includes: a mounting head disposed inside the detection cylinder, wherein the end of the mounting head that contacts the detection cylinder is configured as a smooth sidewall; and a detection head mounted on the bottom of the mounting head.

[0007] As a further embodiment of the present invention, the driving unit includes: a first magnet disposed inside the mounting head; a second magnet disposed outside the detection cylinder; a sleeve fixedly mounted on the top of the base; a rotating cylinder threadedly connected to the sleeve; the second magnet fixedly mounted on the inner wall of the rotating cylinder; and a driving part disposed outside the rotating cylinder and used to drive the rotating cylinder to rotate.

[0008] As a further embodiment of the present invention, the driving unit includes: a first pulley, which is rotatably connected to the sleeve and slidably connected to the rotating drum along the axial direction; the first pulley is connected to a second pulley via a transmission belt; and a motor, which is mounted on the base and is used to drive the second pulley to rotate.

[0009] As a further embodiment of the present invention, the first magnet is slidably connected to the mounting head, and the mounting head is provided with an elastic element for resetting the first magnet; a cavity is opened in the mounting head, and a first piston is slidably installed in the cavity, the first piston is hinged to a connecting rod, and the end of the connecting rod away from the first piston is hinged to the first magnet; a second piston is slidably connected to the bottom end of the cavity; the second piston is fixedly connected to the detection head; and an adjustment unit for adjusting the magnetic force of the second magnet is provided on the outside of the second magnet.

[0010] As a further embodiment of the present invention, the adjustment unit includes an electromagnet, which is installed between the second magnet and the rotating drum.

[0011] As a further embodiment of the present invention, the piston is threadedly connected to the detection head.

[0012] As a further embodiment of the present invention, the elastic element includes a spring, the two ends of which are fixedly connected to a mounting head and a magnet, respectively.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention, through the arrangement of a detection cylinder, a detection unit and a driving unit, allows the balloon placed inside the detection cylinder to fully inflate and fit completely against the inner wall of the detection cylinder. At the same time, the detection unit can apply a stable compressive force to the surface of the balloon to simulate the pressure experienced by the balloon during operation, thereby detecting the uniformity of the balloon.

[0014] 2. This invention can change the pressure of the detection head on the surface of the balloon by adjusting the magnetic force of the electromagnet. When the pressure increases to the point that the balloon ruptures after inflation, it represents the limit pressure that the balloon can withstand after inflation, which can be used to further test the balloon's performance.

Detailed Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figures 1-4 In the attached figure, x represents the balloon that expands when the trigeminal ganglion is compressed, and G represents the point of force application on the surface of the balloon. This invention provides a technical solution: a trigeminal nerve balloon catheter detection device, including a base 1, and further including: a detection cylinder 2, a support base 3, a detection unit 4, and a drive unit; the detection cylinder 2 is fixedly installed on the top of the base 1 through the support base 3, and is configured to have a smaller diameter at both ends and a larger diameter in the middle; the detection unit 4 is disposed inside the detection cylinder 2 and is used to apply compressive force to the expanded balloon; the drive unit is disposed outside the detection cylinder 2 and is used to drive the detection unit 4 to move in a spiral path inside the detection cylinder 2.

[0018] Place the balloon catheter to be tested inside the detection cylinder 2, ensuring the balloon end is in the middle section of cylinder 2; then inject gas into the balloon, inflating it until it completely adheres to the inner wall of cylinder 2; Figure 2 As shown, the detection unit 4 can apply pressure to the surface of the inflated balloon, simulating the pressure experienced when the balloon inflates and compresses the trigeminal ganglion. Simultaneously, the drive unit can drive the detection unit 4 to move along a spiral path on the balloon surface. The detection unit 4 can move along the entire surface of the balloon, continuously applying stable pressure to the balloon surface during movement. When the detection unit 4 moves to the position where it punctures the balloon, it indicates that the balloon is relatively weak at that location, allowing for precise detection of weak points on the balloon surface. Conversely, if the balloon remains intact, the test is passed, and the balloon's uniformity can be verified. This invention, through the arrangement of the detection cylinder 2, the detection unit 4, and the drive unit, ensures that the balloon, after full inflation, can completely adhere to the inner wall of the detection cylinder 2. Simultaneously, the detection unit 4 can apply stable compressive force to the balloon surface to simulate the pressure experienced by the balloon during operation, thereby detecting the balloon's uniformity.

[0019] Specifically, such as Figure 4As shown, the detection unit 4 includes an installation head 5 and a detection head 6; the installation head 5 is disposed inside the detection cylinder 2, and the end of the installation head that contacts the detection cylinder 2 is configured as a smooth sidewall; the detection head 6 is installed at the bottom of the installation head 5; the detection head 6 and the installation head 5 are detachably installed, which facilitates the replacement of detection heads 6 with different shapes to simulate the compression experienced by the balloon during inflation under different environments.

[0020] Specifically, such as Figures 2-4 As shown, the drive unit includes a first magnet 7, a second magnet 8, a rotating cylinder 9, a sleeve 10, and a drive unit; the first magnet 7 is disposed inside the mounting head 5; the second magnet 8 is disposed outside the detection cylinder 2; the sleeve 10 is fixedly mounted on the top of the base 1 via a fixing seat 11; the rotating cylinder 9 is threadedly connected to the sleeve 10; the second magnet 8 is fixedly mounted on the inner wall of the rotating cylinder 10; the drive unit is disposed outside the rotating cylinder 9 and is used to drive the rotating cylinder 9 to rotate; the drive unit includes a first pulley 12 and a motor 15, the first pulley 12 is rotatably connected to the sleeve 10 and slidably connected to the rotating cylinder 9 along the axial direction; the first pulley 12 is driven by a second pulley 14 via a transmission belt 13; the motor 15 is mounted on the base 1 and is used to drive the second pulley 14 to rotate.

[0021] When the drive unit is working, firstly, magnet 8 attracts magnet 7 through the inner wall of the detection cylinder 2; then, motor 15 drives pulley 14 to rotate, and pulley 14 drives pulley 12 to rotate through transmission belt 13; wherein, transmission belt 13 can be tensioned by tensioning wheel to make the rotation of pulley 12 more stable; when pulley 12 rotates, it drives the rotating cylinder 2 to rotate synchronously. Since the rotating cylinder 9 is threadedly connected to the sleeve 10, the rotating cylinder 9 can move towards the sleeve 10 while rotating. Figure 3 The rotating cylinder 9 moves to the right as shown; the rotating cylinder 9 can drive the second magnet 8 to move synchronously. Under the attraction between the second magnet 8 and the first magnet 7, the mounting head 5 can move synchronously with the rotating cylinder 9. The mounting head 5 can drive the detection head 6 to move around the surface of the inflated balloon in a spiral trajectory. When the rotating cylinder 9 moves to the right to the limit and the balloon is not damaged, it indicates that the uniformity of the balloon material is qualified.

[0022] Specifically, such as Figure 4 As shown, magnet 7 is slidably connected to mounting head 5, and an elastic element for resetting magnet 7 is provided inside mounting head 5; a cavity 16 is provided inside mounting head 5, and piston 17 is slidably installed inside cavity 16. Piston 17 is hinged to connecting rod 18, and the end of connecting rod 18 away from piston 17 is hinged to magnet 7; piston 29 is slidably connected to the bottom end of cavity 16; piston 29 is fixedly connected to detection head 6; an adjustment unit for adjusting the magnetic force of magnet 28 is provided on the outside of magnet 28; the adjustment unit includes electromagnet 20, which is installed between magnet 28 and rotating drum 9.

[0023] Because blood vessel diameters vary among people of different ages and weights, the reaction force experienced during balloon inflation differs. Therefore, the balloon's tension limit is an important metric for measurement. When measuring the balloon's tension limit, electromagnet 20 is mounted on magnet 28 to adjust its magnetic force. (Reference) Figure 4 When the top surface of the detection head 6 is in contact with the bottom surface of the mounting head 5, the distance between the tip of the detection head 6 and the inner wall of the detection cylinder 2 is the smallest, and the pressure of the detection head 6 on the surface of the balloon is the smallest. When the rotating cylinder 9 drives the detection head 6 to move to the right limit position through the magnet 8, the magnet 7 and the mounting head 5, the electromagnet 20 increases the magnetic force of the magnet 8. Under the magnetic attraction, the magnet 7 moves upward. The magnet 7 can drive the piston 17 to move outward through the connecting rod 18. Figure 4 The dashed arrow indicates the direction of gas flow in cavity 16 when piston 17 moves outward. The outward movement of piston 17 compresses the gas in cavity 16. Under this pressure, piston 2 19 drives detection head 6 downward, increasing the distance between the tip of detection head 6 and the inner wall of detection cylinder 2, thus increasing the pressure of detection head 6 on the balloon surface. Then, the drive unit drives rotating cylinder 9 to reverse, causing rotating cylinder 9 to move detection head 6 to the left to its initial position via magnet 2 8, magnet 1 7, and mounting head 5. It should be noted that the magnetic force of electromagnet 20 can be adjusted by changing its resistance, a mature existing technology, and will not be elaborated here. Adjusting the magnetic force of electromagnet 20 can change the pressure of detection head 6 on the balloon surface. When the pressure increases to the point that the inflated balloon ruptures, it represents the ultimate pressure the balloon can withstand after inflation, allowing for further testing of balloon performance.

[0024] Specifically, piston 219 is threadedly connected to detection head 6, which facilitates the replacement of detection head 6.

[0025] Specifically, the elastic element includes a spring 21, with both ends of the spring 21 fixedly connected to the mounting head 5 and the magnet 7, respectively; the spring 21 is used for supporting and resetting the magnet 7.
