Description

Technical Field

[0002] Peripheral vascular disease, also known as bronchial disease, has seen a significant increase in incidence in recent years. Common examples include arteriosclerosis obliterans, arteriovenous thrombosis, and aneurysms. Currently, the professional techniques for treating peripheral vascular diseases are constantly evolving, and interventional therapy, as a new treatment method, is being increasingly widely used in clinical practice.

[0003] When performing vascular interventional catheter treatment, part of the catheter needs to be inserted into the patient's body, while part of it remains outside the patient's body. The portion of the catheter outside the patient's body needs to be secured to prevent it from dislodging from the patient's body. Currently, the traditional method of securing the catheter is to use medical tape, which has some inconveniences.

[0004] For example, Chinese invention patent (CN216676666U) discloses an interventional catheter fixation device, which describes: "It includes a fixation strap, two reset mechanisms are fixedly connected to the lower surface of the fixation strap, the bottom end of the reset mechanism is provided with the same placement plate, the lower surface of the fixation strap is provided with a first fixation groove, by setting a telescopic rod, a spring, a fixation strap and a placement plate, the catheter is placed on the surface of a second anti-slip pad, the first strap and the second strap are pulled to complete the fixation of the catheter, when it is necessary to remove the fixation device, the first strap causes the first Velcro to disengage from the second Velcro, so that the first anti-slip pad is disengaged from the catheter, and the catheter is disassembled."

[0005] However, the aforementioned related technologies have the following drawbacks: in actual use, the patient's body is usually pressed on the first and second straps, which means that when the catheter needs to be removed, the patient's body must be moved, which is difficult for some postoperative patients. Therefore, the catheter fixation devices in the aforementioned related technologies are inconvenient to use. To address this, this application proposes a peripheral vascular interventional catheter fixation device to provide a new technical solution to solve the aforementioned technical problems.

[0021] To enable those skilled in the art to better understand the present invention, 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 merely 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 should fall within the scope of protection of the present invention. Example 1:

[0022] Please refer to Figure 1 - Figure 6 A peripheral vascular interventional catheter fixation device, comprising: Installation mechanism 1, with a clamping mechanism 2 for fixing the interventional catheter on the side of the installation mechanism 1, and an adjustment mechanism 3 between the clamping mechanism 2 and the installation mechanism 1. The adjustment mechanism 3 is used for the rotation adjustment of the clamping mechanism 2. The clamping mechanism 2 is connected to the installation mechanism 1 through the adjustment mechanism 3 to meet the catheter fixing requirements at different angles.

[0023] The inner side of the mounting mechanism 1 is slidably connected to the drive seat 4. The end of the adjusting mechanism 3 away from the pipe clamping mechanism 2 is connected to the drive seat 4. The mounting mechanism 1 is also provided with a drive component 5 for driving the drive seat 4, thereby driving the adjusting mechanism 3 and the pipe clamping mechanism 2 to achieve corresponding position adjustments.

[0024] Specifically, the mounting mechanism 1 includes a housing 6. A mounting plate 7 is provided on the side of the housing 6 away from the pipe clamping mechanism 2. Mounting holes are provided at both ends of the mounting plate 7. The entire device can be fixed to the corresponding operating platform or equipment through these mounting holes to ensure the stability of the device during use. The drive base 4 is located inside the housing 6 and is vertically slidably connected to the housing 6.

[0025] Specifically, the drive assembly 5 includes a drive wheel 8, a follower wheel 9, a drive belt 10, and an adjustment knob 11. The drive wheel 8, follower wheel 9, and drive belt 10 are all located inside the outer casing 6. The drive wheel 8 and follower wheel 9 are located at opposite ends of the outer casing 6 and are rotatably connected to the outer casing 6. The drive wheel 8 and follower wheel 9 are connected via the drive belt 10. One side of the drive seat 4 is connected to one side of the drive belt 10. When the drive wheel 8 rotates, the drive seat 4 can slide vertically through the drive belt 10. The adjustment knob 11 is located outside the outer casing 6, and the end of the outer casing 6 is connected to the drive wheel 8. Rotating the adjustment knob 11 rotates the drive wheel 8, thereby driving the drive seat 4.

[0026] Furthermore, a rectangular post 13 is provided at the end of the adjustment knob 11 near the drive wheel 8, and a rectangular insertion hole 14 is provided in the middle of the drive wheel 8. An anti-rotation groove 15 is provided on the side of the outer shell 6 away from the adjustment knob 11. The rectangular post 13, the rectangular insertion hole 14, and the anti-rotation groove 15 are coaxially arranged, and the rectangular post 13 and the rectangular insertion hole 14, as well as the rectangular post 13 and the anti-rotation groove 15, are all plug-in connected. A limit bolt 16 is provided on the mounting plate 7. The limit bolt 16 extends into the inner side of the outer shell 6 through the anti-rotation groove 15. The limit bolt 16 is located inside the rectangular post 13 and is used to limit the movement of the adjustment knob 11 to prevent it from moving axially during rotation and to ensure the stability of the drive. In use, when the adjustment knob 11 is rotated, the rectangular insert 13 and the rectangular socket 14 work together to drive the drive wheel 8 to rotate synchronously. When rotation is not required, the adjustment knob 11 is pressed to insert the rectangular insert 13 into the anti-rotation groove 15, thereby limiting the rotation of the rectangular insert 13 and ensuring that the drive wheel 8 will not rotate. Conversely, when in use, the adjustment knob 11 is pulled out to separate the rectangular insert 13 from the anti-rotation groove 15. The limiting bolt 16 ensures that the rectangular insert 13 will not detach when pulled out.

[0027] Specifically, the adjusting mechanism 3 includes a fixed seat 17 and a rotating seat 18. The fixed seat 17 is connected to the drive seat 4. The end of the rotating seat 18 away from the fixed seat 17 is provided with a connecting bolt 19 for connecting the pipe clamp mechanism 2. The connecting bolt 19 is rotatably connected to the rotating seat 18. The fixed seat 17 and the rotating seat 18 are rotatably connected by a connecting pin 20. Both ends of the connecting pin 20 are provided with a pressing knob 21. By rotating the pressing knob 21, the rotational resistance between the fixed seat 17 and the rotating seat 18 can be adjusted, thereby realizing the flexible adjustment of the turning angle of the pipe clamp mechanism 2. A rubber inner support 22 is sleeved on the outside of the fixed connecting pin 20. The rubber inner support 22 is located inside the connection between the fixed seat 17 and the rotating seat 18. By using the rubber inner support 22 in conjunction with the pressing knob 21, the friction between the fixed seat 17 and the rotating seat 18 can be increased, making the adjusting mechanism 3 more stable after being limited.

[0028] Through the above structural design, this peripheral vascular interventional catheter fixation device can drive the drive seat 4 to move by adjusting the knob 11, thereby driving the adjustment mechanism 3 to adjust the position of the clamping mechanism 2. At the same time, the adjustment mechanism 3 can also realize the rotation adjustment of the clamping mechanism 2, so as to meet the fixation needs of peripheral vascular interventional catheters in different usage scenarios. Example 2:

[0029] The peripheral vascular interventional catheter fixation device provided in Embodiment 1 has been further optimized, specifically, as follows: Figure 7 - Figure 9 As shown, the clamp mechanism 2 includes a clamp body 23, which is U-shaped to facilitate better clamping of the peripheral vascular interventional catheter. A connecting seat 24 is provided at the bent end of the clamp body 23, and a connecting bolt 19 is threadedly connected to the connecting seat 24, thereby achieving a stable connection between the clamp mechanism 2 and the adjustment mechanism 3. A limiting member 25 is provided at the end of the clamp body 23 away from the connecting seat 24. The limiting member 25 is inserted into the clamp body 23, and a U-shaped groove is formed at the end of the limiting member 25 near the clamp body 23 to further enhance the fixation effect on the catheter and prevent the catheter from slipping during the fixation process. An anti-slip soft sleeve 26 is provided at the end of the limiting member 25 away from the tube clamp body 23 and at the position corresponding to the end of the tube clamp body 23. The anti-slip soft sleeve 26 is interference-fitted with the tube clamp body 23, so that when the limiting member 25 is connected to the tube clamp body 23, the friction force generated between the anti-slip soft sleeve 26 and the tube clamp body 23 can realize the movement limitation of the limiting member 25, thereby achieving the fixation effect of the interventional catheter.

[0030] Furthermore, each end of the connecting seat 24 near the rotating seat 18 has a limiting shoulder 27. The rotating seat 18 near the pipe clamp body 23 has multiple anti-slip protrusions 28 arranged in a ring around the connecting bolt 19. When the connecting bolt 19 is tightened with the connecting seat 24, the anti-slip protrusions 28 and the limiting shoulder 27 fit tightly together, preventing the connecting bolt 19 from rotating. Conversely, when the connecting bolt 19 is loosened from the connecting seat 24, the rotational connection between the connecting bolt 19 and the rotating seat 18 allows the pipe clamp mechanism 2 to rotate and adjust its angle to meet the needs of different scenarios. After adjustment, tightening the connecting bolt 19 again limits the pipe clamp mechanism 2, further enhancing the applicability of the pipe clamp mechanism 2. Example 3:

[0031] The peripheral vascular interventional catheter fixation device provided in Embodiment 1 has been further optimized, specifically, as follows: Figure 4As shown, anti-slip protrusions are provided on both sides of the drive seat 4. The drive seat 4 is slidably connected to the outer shell 6 through the anti-slip protrusions to prevent the drive seat 4 from slipping during the sliding process and to ensure the stability of the drive. The anti-slip protrusion on one side of the drive seat 4 is fixedly connected to the drive belt 10 to ensure that the drive belt 10 can effectively drive the drive seat 4 to move. The anti-slip protrusion on the other side of the drive seat 4 has a movable cavity 12 to provide space for the movement of the other side of the drive belt 10, avoid the drive belt 10 from interfering with other components during the movement, and ensure the normal operation of the drive assembly 5.

[0032] Through the above structural design, the connection between the optimized drive seat 4 and the outer shell 6 is more stable, the sliding process is smoother, and a reasonable space is provided for the movement of the drive belt 10, which further improves the driving performance and stability of the entire device.
