Description

Technical Field

[0001] The present invention belongs to the field of vascular intervention technology, in particular to a vascular calcified plaque cutting device. Background Art

[0002] Vascular intervention is a medical method that uses minimally invasive technology to diagnose and treat blood vessels. It usually involves the use of catheters, balloons, stents and other devices to treat various vascular diseases. Vascular intervention is mostly done by using a 1-2mm thick puncture needle to puncture the superficial arteries and veins of the human body to enter the human vascular system. Relying on the knowledge of vascular anatomy, the doctor, under the guidance of the angiography machine, sends the catheter to the location of the lesion, injects contrast agent through the catheter to display the vascular condition of the lesion, and treats the lesion in the blood vessel, including: arterial embolization, angioplasty, etc. Commonly used surface puncture points include the femoral artery and vein, radial artery, subclavian artery and vein, jugular artery and vein, etc.

[0003] Vascular disease refers to various diseases that affect blood vessels, including atherosclerosis, peripheral arterial disease, varicose veins, deep vein thrombosis, hypertension, aneurysms and Raynaud's disease, which are usually related to lifestyle, genetic and environmental factors. Prevention and management include a healthy lifestyle and regular physical examinations. Among them, vascular calcified plaques refer to calcium salt deposits formed in the blood vessel walls, which are usually associated with atherosclerosis. When there are severe calcified plaques in the blood vessels, the diameter of the blood vessel lumen will be significantly reduced, resulting in obstructed blood flow. The hardness and irregular shape of the calcified plaques cause turbulence when the blood passes through these areas, increasing the resistance to blood flow. Existing cutting devices may not fully consider the complexity and variability of calcified plaques in blood vessels when they are designed. When the degree of calcification in the blood vessels is high, the cutting device may not be able to effectively adapt to these changes, resulting in a decrease in cutting ability. The cutting head of the cutting device may not be able to penetrate the hard calcified tissue, or it may generate excessive heat during the cutting process, affecting the cutting effect.

[0004] A Chinese invention patent publication number CN114642477B discloses a device for cutting vascular calcified plaques. The key points of its technical solution are: it includes a tip, an inner tube, an outer tube and a cutting unit, the distal end of the inner tube is connected to the tip; the outer tube is movably connected to the inner tube, the outer tube includes a first tube segment and a second tube segment, the proximal end of the first tube segment is connected to the distal end of the second tube segment, and the first tube segment is provided with an ultrasonic generating component; the distal end of the cutting unit is connected to the tip, the proximal end of the cutting unit is connected to the connection between the first tube segment and the second tube segment, and two or more cutting units are distributed circumferentially around the inner tube.

[0005] The beneficial effects of the vascular calcified plaque cutting device provided by the above invention are: the cutting unit can cut the calcified plaque, the ultrasonic generating component emits ultrasonic waves for vibrating and expanding the cracks in the calcified plaque, and two or more cutting units are close together and contracted, with good passability, which solves the technical problem that the existing vascular calcified plaque cutting device cannot achieve both strong passability and good cutting effect.

[0006] However, the above technology often has the following defects: when cutting vascular calcified plaques, the cut calcified plaques cannot be removed in time, which will affect the cutting knife trajectory during cutting, making it difficult for the cutter to accurately enter the appropriate position, making the cutting of the calcified plaques incomplete, and there is no interception device for the cut calcified plaques, which may float to deeper blood vessels, causing new blood vessel stenosis and may also trigger acute thrombosis. At the same time, due to the different hardness and shapes of calcified plaques, it is difficult to guarantee the thickness of the cut calcified plaques when directly cutting with a cutter, and it is not convenient to cut evenly, which may easily lead to the inability to completely remove the calcified plaques, thereby affecting the treatment effect. Moreover, if the cutter is improperly operated or the cutting force is too strong during the cutting process, it may cause direct damage to the blood vessel wall, thereby causing bleeding.

[0007] To this end, the present invention provides a device for cutting vascular calcified plaques. Summary of the Invention

[0020] The beneficial effects of the present invention are as follows:

[0021] 1. The vascular calcified plaque cutting device of the present invention has an adsorption component. During the process of the rotating component performing rotational grinding on the calcified plaque, the fan blades rotate synchronously with the driving shaft, so that a negative pressure state is formed above the fan blades, thereby adsorbing the calcified plaques under the rotational grinding to the bottom of the fan blades.

Combined with the airbag, the fixed frame can be completely sealed, thereby preventing the calcified plaque from floating to deeper blood vessels during the subsequent calcified plaque removal process, causing new blood vessel stenosis or triggering acute thrombosis.

[0023] 3. The vascular calcified plaque cutting device of the present invention, through the use of the provided rotating assembly and the laser cutting head, drives the grinding wheel to rotate forward along the guide wire, grinding the calcified plaque, thereby opening the channel to facilitate the passage of the laser cutting head, and then uses the laser cutting head to heat the remaining calcified plaque close to the blood vessel wall to a high temperature, so that it evaporates or melts quickly. The combination of the two can effectively avoid poor passing ability due to stenotic lesions, and improper operation or excessive cutting force may cause direct damage to the blood vessel wall, thereby causing bleeding.

[0024] 4. The vascular calcified plaque cutting device of the present invention is provided with a measuring component and a detection component. One end of the third spring is fixedly connected to the outer surface of the sheath near the bottom of the connecting frame, supporting the lower surface of the measuring ruler in an inclined shape. When the sheath is away from the outer tube, the elastic force of the third spring pushes the measuring ruler to pop out, so that the measuring ruler is located at the lower periphery of the residual calcified plaque. The driving motor is started to drive the camera to rotate left and right. The thickness of the residual calcified plaque is measured by the camera in combination with the measuring ruler, which facilitates the effective understanding of the thickness of the calcified plaque, and then the laser cutting head is used to clean it, facilitate uniform cutting, and ensure the treatment effect.

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0038] Example 1: Figures 1 to 10 As shown, the embodiment of the present invention is as follows:

[0039] It includes a rotating component, the middle of the outer surface of the rotating component is fixedly connected to the adsorption component, the lower surface of the adsorption component is provided with a slide groove 35, both ends of the slide groove 35 are fixedly connected to the first electromagnetic block 1, the middle of the slide groove 35 is slidably connected to the closing component, the lower surface of the closing component is adsorbed with the second electromagnetic block 2, the lower surface of the second electromagnetic block 2 is fixedly connected to the air supply component, the outer surface of the air supply component is provided with a through groove, the inside of the through groove is fixedly connected to the degassing component, the bottom end of the outer surface of the rotating component is sleeved with a sheath 3, the top end of the outer surface of the sheath 3 is fixedly installed with a laser cutting head 4, the middle part of the outer surface of the sheath 3 is connected with a measuring component, the outer surface of the sheath 3 is located below the measuring component and is fixedly connected with a detection component, the outer surface of the sheath 3 is sleeved with an outer tube 5, the inner side wall of the outer tube 5 is provided with an installation groove, and the inside of the installation groove is fixedly connected with a pushing component.

[0040] The adsorption component includes a fan blade 9, and the middle rotating seat of the fan blade 9 is coaxially fixedly connected to the outer surface of the drive shaft 6. The upper and lower ends of the middle rotating seat of the fan blade 9 are fixedly connected to a fixed frame 10, and the outer surface of the fixed frame 10 is covered and fixed with an air bag 11. During the process of the rotating component performing rotational grinding on the calcified plaque, the fan blade 9 rotates synchronously with the drive shaft 6, so that a negative pressure state is formed above the fan blade 9, thereby adsorbing the calcified plaque under the rotational grinding to the bottom of the fan blade 9, and the calcified plaque dropped by the rotational grinding can be removed in time to avoid affecting the rotational grinding of the grinding wheel 7, causing the grinding wheel 7 to deviate from the track and affect its use. At the same time, after the rotational grinding is completed, the air bag 11 is inflated so that the edge of the air bag 11 is close to the inner wall of the blood vessel, and then combined with the sealing component, the fixed frame 10 is closed, thereby blocking the dropped calcified plaque to the bottom of the fixed frame 10, which can prevent the calcified plaque under the rotational grinding from floating to deeper blood vessels and affecting the purity of the blood vessels.

[0041] The sealing component includes a third electromagnetic block 12, the outer surface of the third electromagnetic block 12 is slidably connected to the middle of the slide groove 35, the lower surface of the third electromagnetic block 12 is fixedly connected to the sealing bag 13, and the lower surface of the sealing bag 13 is fixedly connected to the fourth electromagnetic block 14. The sealing bag 13 is made of completely sealed material. When the fan moves, the first electromagnetic block 1 inside the slide groove 35 is electrically conductive and adsorbs the third electromagnetic block 12. The second electromagnetic block 2 and the fourth electromagnetic block 14 are in a magnetic state at the same time. At this time, the sealing bag 13 is in a contracted state and attached to the outer surface of the drive shaft 6 to prevent it from intercepting the calcified plaque dropped by the grinding. After the grinding is completed, the fan blades 9 stop rotating, and then charge the first electromagnetic block 1 outside the slide groove 35, and adsorb the third electromagnetic block 12, so that the upper end of the sealing bag 13 is expanded to seal the lower surface of the fixed frame 10, to prevent the calcified plaque from floating to deeper blood vessels during the subsequent calcified plaque removal process, causing new blood vessel stenosis or triggering acute thrombosis.

[0042] The air supply assembly includes a fixing ring 15, the upper surface of the fixing ring 15 is fixedly connected to the lower surface of the second electromagnetic block 2, the lower surface of the fixing ring 15 is fixedly connected to a push rod 16, the bottom end of the push rod 16 is fixedly connected to a sealing ball 17, the outer surface of the sealing ball 17 is clamped with a connecting rod 18, the upper surface of the connecting rod 18 is fixedly connected to a first spring 19, the top end of the outer surface of the connecting rod 18 is fixedly connected to an air pipe 20, and the bottom end of the outer surface of the connecting rod 18 is fixedly connected to an air supply bag 21. The bottom end of the outer surface of the bag 21 is fixedly connected to a force block 22, which pushes the air supply bag 21 to move upward, squeezes the first spring 19, and the push rod 16 pushes the sealing ball 17 downward, so that the sealing ball 17 moves away from the connecting rod 18. The gas inside the air supply bag 21 floats up and enters the inside of the connecting rod 18, and enters the inside of the air bag 11 through the trachea 20, inflating the inside of the air bag 11, so that the outer periphery of the fixed frame 10 is close to the inner wall of the blood vessel, thereby sealing the top of the calcified plaque.

[0043] The deflation component includes an air port 23, the outer surface of the air port 23 is fixedly connected to the inside of the through groove, the back of the air port 23 is fixedly connected to a second spring 24, and one end of the second spring 24 is fixedly connected to a sealing plate 25. The outer tube 5 is moved upward to allow the pushing ball 34 to enter the interior of the air port 23 and push the sealing plate 25. The second spring 24 is stretched to make the sealing plate 25 away from one end of the air port 23, thereby discharging the gas inside the air supply airbag 21 and making the air pressure inside the air supply airbag 21 lower than the air pressure inside the airbag 11. When used in combination with the air supply component, the gas inside the airbag 11 can be discharged, making it convenient to remove the device from the body.

[0044] The pushing assembly includes a box body 32, the outer surface of the box body 32 is fixedly connected to the inside of the mounting groove, the inner bottom wall of the box body 32 is fixedly connected to a fourth spring 33, and one end of the fourth spring 33 is fixedly connected to a pushing ball 34. When the assembly is aligned with the deflation assembly, the fourth spring 33 pushes the pushing ball 34 to squeeze the sealing plate 25 away from the air port 23 for deflation.

[0045] The diameter of the outer tube 5 is larger than the diameter of the air supply bag 21 , and the pushing assembly is adapted to the deflation assembly. The outer tube 5 can be moved to the periphery of the air supply bag 21 so that the pushing assembly and the deflation assembly can be docked.

[0046] The first electromagnetic block 1 is adapted to the third electromagnetic block 12, and the second electromagnetic block 2 is adapted to the fourth electromagnetic block 14. When the first electromagnetic block 1 and the third electromagnetic block 12 outside the chute 35 generate magnetic attraction, the second electromagnetic block 2 moves away from the fourth electromagnetic block 14, so that the upper part of the sealing bag 13 is unfolded to seal the lower surface of the fixed frame 10. When the first electromagnetic block 1 and the third electromagnetic block 12 inside the chute 35 generate magnetic attraction, the second electromagnetic block 2 and the fourth electromagnetic block 14 are in a magnetic attraction state at the same time, so that the sealing bag 13 is in a contracted state and tightly attached to the periphery of the drive shaft 6, so as to avoid affecting the adsorption of the calcified plaque under the rotational grinding by the fan blades 9.

[0047] Example 2: Figures 1 to 10 As shown in Comparative Example 1, another embodiment of the present invention is:

[0048] The rotating assembly includes a drive shaft 6, which is hollow. The middle part of the outer surface of the drive shaft 6 is fixedly connected to the middle part of the adsorption assembly. The top end of the outer surface of the drive shaft 6 is fixedly connected to a coaxial grinding wheel 7. The middle part of the drive shaft 6 is sleeved with a guide wire 8. The outer surface of the grinding wheel 7 is covered with abrasive, and the abrasive can be selected from aluminum oxide, silicon carbide or diamond to improve the cutting efficiency. In actual operation, the drive shaft 6 is connected to the high-frequency motor at the extension of the blood vessel. Driven by the high-frequency motor and guided by the guide wire 8, the drive shaft 6 drives the grinding wheel 7 to rotate forward and rub against the calcified plaque. The hardness and sharpness of the abrasive enable it to effectively cut and remove calcified materials, thereby opening the channel and facilitating the passage of the laser cutting head 4, which can effectively avoid the problem of poor passability for stenotic lesions.

[0049] The measuring assembly includes a connecting frame 26, one side of which is fixedly connected to the middle part of the outer surface of the sheath 3, and a measuring ruler 27 is connected to the side of the connecting frame 26 facing away from the sheath 3 through a rotating rod. The lower surface of the measuring ruler 27 is fixedly connected to a third spring 28, and scale lines are provided on the upper and lower sides of the measuring ruler 27. One end of the third spring 28 is fixedly connected to the outer surface of the sheath 3 near the bottom of the connecting frame 26, and supports the lower surface of the measuring ruler 27 in an inclined shape. When not in operation, the measuring assembly is limited by the outer tube 5, and the device is inside the outer tube 5. When it is necessary to measure the calcified plaque, the sheath 3 is pushed forward to move the front end of the sheath 3 away from the outer tube 5. At this time, under the elastic force of the third spring 28, the measuring ruler 27 is pushed out, so that the measuring ruler 27 is at the lower periphery of the residual calcified plaque, which is convenient for providing a measurement reference for the detection assembly.

[0050] The detection component includes a mounting bracket 29, one side of the mounting bracket 29 is fixedly connected to the outer surface of the sheath 3 and is located below the measuring component. A driving motor 30 is fixedly installed on one side of the mounting bracket 29, and a camera 31 is fixedly connected to the output end of the driving motor 30. The driving motor 30 is started to drive the camera 31 to rotate left and right. The calcified plaque is captured by the camera 31 or the measuring scale of the measuring ruler 27 is captured. The thickness of the residual calcified plaque is measured in combination with the measuring ruler 27, so as to effectively understand the thickness of the calcified plaque, and then clean it through the laser cutting head 4 to facilitate uniform cutting to ensure the treatment effect.

[0051] Working principle: First, the driving shaft 6 is connected to the high-frequency motor at the point where it extends out of the blood vessel. Driven by the high-frequency motor and guided by the guide wire 8, the driving shaft 6 drives the grinding wheel 7 to rotate forward to grind the calcified plaque. At the same time, the fan blades 9 rotate synchronously with the driving shaft 6, so that a negative pressure state is formed above the fan blades 9, thereby adsorbing the calcified plaque under grinding to the bottom of the fan blades 9, and the calcified plaque dropped by grinding can be removed in time. Then, after the grinding wheel 7 rotates through the closed calcified plaque, a channel is formed in the middle of the calcified plaque, driving the fixed frame 10 to pass through the calcified plaque at the same time, and the sealing bag 13 is made of a completely sealed material. When the fan moves, the first inner side of the slide groove 35 The electromagnetic block 1 is electrically conductive and absorbs the third electromagnetic block 12. The second electromagnetic block 2 and the fourth electromagnetic block 14 are in a magnetic state at the same time. At this time, the sealing bag 13 is in a contracted state and attached to the outer surface of the drive shaft 6 to prevent it from intercepting the calcified plaques that fall off during the grinding. After the grinding is completed, the fan blades 9 stop rotating, and then charge the first electromagnetic block 1 outside the chute 35, so that the first electromagnetic block 1 and the third electromagnetic block 12 outside the chute 35 are magnetically attracted, and the second electromagnetic block 2 is away from the fourth electromagnetic block 14, so that the upper end of the sealing bag 13 is unfolded, and the lower surface of the fixed frame 10 is sealed, and then the air supply airbag 21 is pushed upward to squeeze the first spring 19 and push it up. The rod 16 pushes the sealing ball 17 downward, thereby moving the sealing ball 17 away from the connecting rod 18, and the gas inside the air supply bag 21 floats up and enters the inside of the connecting rod 18, and enters the inside of the air bag 11 through the trachea 20, inflating the inside of the air bag 11, so that the periphery of the fixed frame 10 is close to the inner wall of the blood vessel. Secondly, one end of the third spring 28 is fixedly connected to the outer surface of the sheath 3 near the bottom of the connecting frame 26, and supports the lower surface of the measuring ruler 27 in an inclined shape. When the sheath 3 is away from the outer tube 5, the elastic force of the third spring 28 pushes the measuring ruler 27 to pop out, so that the measuring ruler 27 is at the lower periphery of the residual calcified plaque, and the drive motor 30 is started to drive the camera 31 rotates left and right, and the thickness of the residual calcified plaque is measured by the camera 31 in combination with the measuring ruler 27, so as to effectively understand the thickness of the calcified plaque, and then clean it through the laser cutting head 4. Finally, the outer tube 5 is moved upward to allow the pushing ball 34 to enter the air port 23. The fourth spring 33 pushes the pushing ball 34 to push the sealing plate 25. The second spring 24 stretches the sealing plate 25 away from one end of the air port 23, thereby discharging the gas inside the air supply airbag 21, making the air pressure inside the air supply airbag 21 lower than the air pressure inside the airbag 11. When used in combination with the air supply component, the gas inside the airbag 11 can be discharged, making it convenient to remove the device from the body.
