Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and specifically relates to an auxiliary device for left atrial appendage occlusion in atrial fibrillation. Background Art

[0002] Left atrial appendage occlusion in atrial fibrillation is an interventional treatment method for preventing stroke in patients with atrial fibrillation. Through a minimally invasive interventional approach, percutaneous puncture is performed, and a septal puncture is used to place a occluder device at the opening of the left atrial appendage, isolating the inner cavities of the left atrium and the left atrial appendage, and isolating the left atrial appendage from the systemic circulation to prevent thrombus from detaching and entering the blood circulation to cause embolism.

[0003] When performing the left atrial appendage occlusion surgery for atrial fibrillation, a variety of auxiliary devices are required to ensure the smooth progress of the surgery. For example, digital subtraction angiography in image guidance equipment injects contrast agents to clearly display blood vessels and heart structures on the monitor, helping doctors determine the positions of catheters and occluders and guiding them to accurately reach the left atrial appendage. However, in actual use, most of the monitors of digital subtraction angiography are installed on movable vertical poles, which can only move horizontally and adjust the angle horizontally, and cannot adjust the angle of the monitor vertically, thus limiting the angle adjustment range of the monitor.

Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Such as Figures 1 to 10As shown in the figure, an atrial fibrillation left atrial occlusion assisting device is provided in an embodiment of the present invention, which includes a vertical rod 1. A spherical ball 2 is movably sleeved at the bottom end of the vertical rod 1. An installation rod 3 is fixedly installed at the bottom end of the spherical ball 2. A fixed frame 4 is fixedly installed at the front end of the installation rod 3. A display 5 is fixedly sleeved inside the fixed frame 4. A rubber pad 6 is movably sleeved at the bottom of the vertical rod 1. A vertical rod 7 is fixedly installed at the top end of the rubber pad 6. An inclined rod 8 is hinged at the top end of the vertical rod 7. The other end of the inclined rod 8 is hinged to a rectangular block 9. The outer surface of the rectangular block 9 is movably sleeved with the inner surface of the vertical rod 1. A threaded rod 10 is threadedly sleeved inside the rectangular block 9. Handles 11 are respectively fixedly sleeved at the left and right ends of the outer surface of the threaded rod 10. Support blocks 12 are respectively movably connected to the left and right sides of the outer surface of the threaded rod 10. The number of both the handles 11 and the support blocks 12 is two. The opposite surfaces of the two handles 11 are respectively movably connected to the opposite surfaces of the two support blocks 12. The opposite surfaces of the two support blocks 12 are respectively fixedly connected to the outer surface of the vertical rod 1.

[0031] When the handle 11 is rotated, the threaded rod 10 will rotate along the inner surface of the support block 12. Since the threaded rod 10 is threadedly sleeved with the rectangular block 9, as the threaded rod 10 rotates, the rectangular block 9 will move along the inner surface of the vertical rod 1, so that the inclined rod 8 hinged to the rectangular block 9 will move together, and then a thrust will be generated on the vertical rod 7 at the other end of the inclined rod 8, pushing the vertical rod 7 to drive the rubber pad 6 to move towards the spherical ball 2, thereby pressing and fixing the rotation position of the spherical ball 2. And because the spherical ball 2 is movably sleeved at the bottom end of the vertical rod 1, the angles of the fixed frame 4 and the display 5 can be adjusted by means of the spherical ball 2, thus increasing the range of angle adjustment of the fixed frame 4 and the display 5.

[0032] Wherein, a round rod 13 is fixedly sleeved in the middle of the vertical rod 7. A limit block 14 is movably sleeved in the middle of the outer surface of the round rod 13. The outer surface of the limit block 14 is fixedly sleeved with the inner surface of the vertical rod 1.

[0033] The mutual cooperation of the round rod 13 and the limit block 14 will limit the movement of the vertical rod 7, thereby ensuring the stability of the movement of the vertical rod 7 and preventing the vertical rod 7 from driving the rubber pad 6 to deviate from its position during the movement.

[0034] Wherein, a top block 15 is fixedly installed at the top end of the vertical rod 1. Rollers 16 are respectively movably installed at the left and right ends of the top block 15. A guide rail 17 is movably sleeved on the outer surface of the roller 16.

[0035] When the vertical rod 1 is pushed, since the roller 16 is movably sleeved with the guide rail 17, the vertical rod 1 will drive the top block 15 and the roller 16 to move along the inner surface of the guide rail 17, thereby adjusting the positions of the fixed frame 4 and the display 5.

[0036] Among them, the left and right sides of the middle part of the top of the top block 15 are respectively movably connected with pressing rods 18. The number of pressing rods 18 is two. Anti-slip pads 19 are respectively fixedly installed on the opposite sides of the two pressing rods 18. T-shaped blocks 20 are respectively movably sleeved on the outer sides facing away from the inside of the two pressing rods 18. The bottom ends of the T-shaped blocks 20 are fixedly connected with the top end of the top block 15.

[0037] When the pressing rod 18 is pushed, it will move along the outer surface of the T-shaped block 20 with the anti-slip pad 19, so as to press the guide rail 17 through the anti-slip pad 19 to realize the positioning of the position of the top block 15 and prevent the top block 15 from shifting in position after the position is adjusted.

[0038] Among them, round blocks 21 are respectively fixedly installed on the adjacent sides of the tops of the two pressing rods 18. The outer surfaces of the round blocks 21 are movably sleeved with rotating rods 22. The bottom ends of the rotating rods 22 are movably connected with the tops of the pressing rods 18. The number of the round blocks 21 and the rotating rods 22 is two, and they are respectively centrosymmetric about the center of the top block 15.

[0039] When the two rotating rods 22 rotate in opposite directions, since the inner surface of the rotating rod 22 is movably sleeved with the outer surface of the round block 21, as the rotating rod 22 rotates, the rotating rod 22 will generate a thrust on the round block 21, pushing the round block 21 to drive the pressing rod 18 to move away from each other.

[0040] Among them, a fixed block 23 is fixedly installed on the top of the right side of the rear end of the top block 15. A fixed shaft 24 is fixedly installed on the top of the fixed block 23. The outer surface of the fixed shaft 24 is movably sleeved with the inner surface of the rear end of the rotating rod 22. A first gear 25 is movably sleeved on the outer surface of the fixed shaft 24. The top of the first gear 25 is fixedly connected with the rear side of the bottom end of the rotating rod 22.

[0041] When the first gear 25 rotates, since the first gear 25 is fixedly connected with the rotating rod 22, the first gear 25 will drive the rotating rod 22 to rotate around the fixed shaft 24, and the fixed block 23 can play a role in supporting and fixing the fixed shaft 24.

[0042] Among them, a servo motor 26 is fixedly installed on the top of the left side of the rear end of the top block 15. The other end of the output shaft of the servo motor 26 is fixedly sleeved with a rotating shaft 27. The top of the outer surface of the rotating shaft 27 is fixedly sleeved with the inner surface of the rear end of the rotating rod 22. A second gear 28 located below the rotating rod 22 is fixedly sleeved on the outer surface of the rotating shaft 27. The outer surface of the second gear 28 is meshed with the outer surface of the first gear 25.

[0043] When the servo motor 26 is started, it will cause the rotating shaft 27 to drive the second gear 28 and the rotating rod 22 to rotate. Since the second gear 28 and the first gear 25 are meshed with each other, under the action of the second gear 28, the first gear 25 will drive the other rotating rod 22 to rotate in the opposite direction.

[0044] Among them, support blocks 29 are fixedly installed at the left and right ends of the top of the front end of the vertical rod 1 respectively. An activity shaft 30 is movably sleeved inside the support block 29. Cover plates 31 are fixedly sleeved on the left and right sides of the outer surface of the activity shaft 30 respectively. The outer surface of the cover plate 31 is movably connected to the outer surface of the support block 29.

[0045] Since the cover plate 31 and the activity shaft 30 are fixedly sleeved and the activity shaft 30 and the support block 29 are movably sleeved, when the cover plate 31 is toggled, the cover plate 31 will drive the activity shaft 30 to rotate around the activity shaft 30 as the axis.

[0046] Among them, a connecting gear 32 is fixedly sleeved in the middle of the outer surface of the activity shaft 30. A clamping rod 33 is movably connected to the rear side of the outer surface of the connecting gear 32. The outer surface of the clamping rod 33 is movably sleeved with the inner surface of the middle part of the top end of the fixed frame 4. A stop block 34 is movably sleeved at the rear end inside the clamping rod 33. The outer surface of the stop block 34 is fixedly sleeved with the inner surface of the middle part of the top end of the fixed frame 4. A spring 35 is fixedly installed at the front end of the stop block 34. The other end of the spring 35 is fixedly connected to the inner surface of the clamping rod 33.

[0047] When the connecting gear 32 rotates, the teeth on the outer surface of the connecting gear 32 will squeeze the clamping rod 33, causing the clamping rod 33 to move along the outer surface of the stop block 34 and continue to compress the spring 35. Under the restoring action of the spring 35, the clamping rod 33 will be forced to return to its original position.

[0048] Working principle and usage process:

[0049] First, the operator pushes the vertical rod 1, causing the vertical rod 1 to drive the top block 15 and the rollers 16 to move along the inner surface of the guide rail 17 until the vertical rod 1 moves to the designated position. Then the operator starts the servo motor 26, causing the rotating shaft 27 to drive the second gear 28 to rotate. Since the first gear 25 and the second gear 28 are meshed with each other, under the combined action of the first gear 25 and the second gear 28, the two rotating rods 22 will rotate in opposite directions, so that a thrust will be generated on the outer surface of the round block 21 by the inner surface of the rotating rod 22, pushing the two round blocks 21 to drive the pressure rods 18 and the anti-slip pads 19 to move away from each other along the outer surface of the T-shaped block 20 until the anti-slip pads 19 press tightly against the guide rail 17 to position the position of the top block 15, thereby preventing the top block 15 from shifting in position during the operation.

[0050] Subsequently, the operator toggles the cover plate 31, causing the cover plate 31 to drive the movable shaft 30 and the connecting gear 32 to rotate along the inner surface of the support block 29. As the connecting gear 32 rotates, the teeth on the outer surface of the connecting gear 32 will squeeze the latch rod 33, causing the latch rod 33 to move along the outer surface of the stopper 34 and compress the spring 35. Under the restoring action of the spring 35, when the cover plate 31 is completely closed, the latch rod 33 will return to its original position and re-lock the positions of the connecting gear 32 and the cover plate 31. In this way, the protection of the display 5 can be achieved by means of the cover plate 31, thereby preventing the display 5 from being damaged by collision.

[0051] Finally, the operator toggles the fixing frame 4, causing the fixing frame 4 to drive the display 5, the mounting rod 3, and the ball 2 to rotate with the ball 2 as the pivot point until the display 5 rotates to a position convenient for the operator to view. Subsequently, the operator rotates the handle 11, causing the threaded rod 10 to rotate along the inner surface of the support block 12. As a result, the rectangular block 9 threadedly sleeved on the threaded rod 10 drives one end of the inclined rod 8 to move, and further causes the other end of the inclined rod 8 to exert a thrust on the vertical rod 7, pushing the vertical rod 7 with the rubber pad 6 to move along the outer surface of the limit block 14 and press tightly against the fixed ball 2. In this way, the angle adjustment of the fixing frame 4 and the display 5 can be achieved, thereby increasing the range of its angle adjustment.
