Description

Vascular calcification plaque cutting equipment Technical Field

[0001] This invention belongs to the field of vascular interventional technology, specifically a device for cutting calcified plaques in blood vessels. Background Technology

[0002] Interventional vascular surgery is a minimally invasive medical procedure for diagnosing and treating blood vessels. It typically involves using catheters, balloons, stents, and other devices to treat various vascular diseases. Interventional procedures usually involve using a 1-2mm diameter needle to puncture superficial arteries and veins to access the vascular system. Guided by an angiography machine, the doctor, with knowledge of vascular anatomy, guides the catheter to the location of the lesion. Contrast agents are injected through the catheter to visualize the vascular lesion. Treatment methods include arterial embolization and angioplasty. Commonly used superficial puncture sites include the femoral artery and vein, radial artery, subclavian artery and vein, and carotid artery and vein.

[0003] Vascular diseases refer to various conditions affecting blood vessels, including atherosclerosis, peripheral artery disease, varicose veins, deep vein thrombosis, hypertension, aneurysms, and Raynaud's disease. These are typically related to lifestyle, genetics, and environmental factors. Prevention and management include a healthy lifestyle and regular checkups. Among these, vascular calcification plaques refer to calcium salt deposits that form within the blood vessel walls, usually associated with atherosclerosis. When severe calcification plaques are present, the diameter of the blood vessel lumen significantly decreases, obstructing blood flow. The hardness and irregular shape of calcification plaques cause turbulence when blood passes through these areas, increasing resistance. Existing cutting devices may not have adequately considered the complexity and variability of vascular calcification plaques in their design. When the degree of calcification is high, the cutting device may not be able to effectively adapt to these changes, leading to decreased cutting ability. The cutting tip may not be able to penetrate the hard calcified tissue, or excessive heat may be generated during the cutting process, affecting the cutting effect.

[0004] A Chinese invention patent with publication number CN114642477B discloses a device for cutting calcified plaques in blood vessels. The key technical points of the device 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 sleeved on 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. The first tube segment is equipped with an ultrasonic wave generating element. The distal end of the cutting unit is connected to the tip, and the proximal end of the cutting unit is connected to the junction of the first tube segment and the second tube segment. Two or more cutting units are circumferentially spaced around the inner tube.

[0005] The beneficial effects of the vascular calcification plaque cutting device provided by the above invention are: the cutting unit can cut calcification plaques, the ultrasonic generating element emits ultrasonic waves to vibrate and expand the cracks in the calcification plaques, and two or more cutting units close together and contract, resulting in good throughput. This solves the technical problem that existing vascular calcification plaque cutting devices cannot simultaneously achieve both strong throughput and good cutting effect.

[0006] However, the aforementioned techniques often have the following drawbacks: When cutting calcified plaques in blood vessels, the inability to promptly remove the cut calcified plaques can affect the cutting trajectory, making it difficult for the cutting blade to accurately enter the appropriate position. This can result in incomplete removal of the calcified plaques. Furthermore, without an interception device, the cut calcified plaques may float to deeper blood vessels, leading to new vascular stenosis and potentially triggering acute thrombosis. Additionally, due to the varying hardness and shape of calcified plaques, direct cutting with a blade makes it difficult to ensure the thickness of the cut calcified plaques, hindering uniform cutting and making it easy for calcified plaques to be incompletely removed, thus affecting the treatment effect. Moreover, improper operation or excessive cutting force during the cutting process may directly damage the blood vessel wall, leading to bleeding.

[0007] Therefore, the present invention provides a device for cutting calcified plaques in blood vessels. Summary of the Invention

[0008] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0010] The rotating assembly includes a drive shaft, which is hollow. The middle part of the outer surface of the drive shaft is fixedly connected to the middle part of the adsorption assembly. A coaxial grinding wheel is fixedly connected to the top of the outer surface of the drive shaft, and a guide wire is sleeved in the middle of the drive shaft.

[0011] The adsorption assembly includes a fan blade, the central rotating seat of the fan blade is coaxially and fixedly connected to the outer surface of the drive shaft, and a fixing frame is fixedly connected to both the upper and lower ends of the central rotating seat of the fan blade, and an airbag is fixedly covered on the outer surface of the fixing frame.

[0012] The sealing assembly includes a third electromagnetic block, the outer surface of which is slidably connected to the middle of the groove, a sealing bag is fixedly connected to the lower surface of the third electromagnetic block, and a fourth electromagnetic block is fixedly connected to the lower surface of the sealing bag.

[0013] The air supply assembly includes a fixing ring, the upper surface of which is fixedly connected to the lower surface of the second electromagnetic block. A push rod is fixedly connected to the lower surface of the fixing ring, and a sealing ball is fixedly connected to the bottom end of the push rod. A connecting rod is snapped onto the outer surface of the sealing ball. A first spring is fixedly connected to the upper surface of the connecting rod. An air tube is fixedly connected to the top end of the outer surface of the connecting rod. An air supply airbag is fixedly connected to the bottom end of the outer surface of the connecting rod. A force-bearing block is fixedly connected to the bottom end of the outer surface of the air supply airbag.

[0014] The venting assembly includes an air inlet, the outer surface of which is fixedly connected to the inside of the through groove, and a second spring is fixedly connected to the back of the air inlet. A sealing plate is fixedly connected to one end of the second spring.

[0015] The measuring component includes a connecting frame, one side of which is fixedly connected to the middle of the outer surface of the sheath, and the side of the connecting frame facing away from the sheath is rotatably connected to a measuring scale via a rotating rod. A third spring is fixedly connected to the lower surface of the measuring scale, and scale lines are provided on both the upper and lower sides of the measuring scale.

[0016] The detection component includes a mounting bracket, one side of which is fixedly connected to the outer surface of the protective sleeve and located below the measuring component. A drive motor is fixedly mounted on one side of the mounting bracket, and a camera is fixedly connected to the output end of the drive motor.

[0017] The push assembly includes a box body, the outer surface of which is fixedly connected to the inside of the mounting groove, and a fourth spring is fixedly connected to the inner bottom wall of the box body. One end of the fourth spring is fixedly connected to a push ball.

[0018] The diameter of the outer tube is larger than the diameter of the air supply bladder, and the pushing assembly is adapted to the deflation assembly.

[0019] The first electromagnetic block is adapted to the third electromagnetic block, and the second electromagnetic block is adapted to the fourth electromagnetic block.

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

[0021] 1. The vascular calcified plaque cutting device of the present invention, through the adsorption component, during the rotation of the rotating component to grind the calcified plaque, the fan blade rotates synchronously with the drive shaft, creating a negative pressure state above the fan blade, thereby adsorbing the calcified plaques that have been ground down to the area below the fan blade. This allows for the timely removal of calcified plaques that have fallen off during grinding, preventing them from affecting the grinding wheel and causing the wheel track to deviate, thus affecting its use. At the same time, after grinding is completed, the airbag is inflated so that the edge of the airbag is tightly attached to the inner wall of the blood vessel. Combined with the sealing component, the fixing frame is sealed, thereby blocking the fallen calcified plaques to the area below the fixing frame. This prevents the calcified plaques that have been ground down from floating to deeper parts of the blood vessel and affecting the purity of the blood vessel.

[0022] 2. The vascular calcification plaque cutting device of the present invention, through the setting of an airbag and a sealing component, and the fact that the width of the fixing frame and the grinding wheel are the same size, after the grinding wheel rotates and passes through the sealed calcification plaque, a track is formed in the middle of the calcification plaque. At the same time, the fixing frame is driven to pass through the calcification plaque, charging the first electromagnetic block on the outside of the slide groove and attracting the third electromagnetic block, thereby causing the upper end of the sealing bag to unfold and sealing the lower surface of the fixing frame. Combined with the airbag, the fixing frame can be completely sealed, preventing the calcification plaque from floating to deeper blood vessels during the subsequent calcification plaque removal process, which could lead to new vascular stenosis or cause acute thrombosis.

[0023] 3. The vascular calcification plaque cutting device of the present invention, through the use of the set rotating component and the laser cutting head, drives the grinding wheel to rotate forward along the guide belt, grinds the calcification plaque, thereby opening the channel to facilitate the passage of the laser cutting head. Then, the laser cutting head is used to heat the remaining calcification plaque close to the blood vessel wall to a high temperature, so that it evaporates or melts rapidly. The combination of the two can effectively avoid the poor passage capacity caused by stenosis lesions, and the direct damage to the blood vessel wall caused by improper operation or excessive cutting force, which may lead to bleeding.

[0024] 4. The vascular calcification plaque cutting device of the present invention, through the setting of measuring components and detection components, has one end of a third spring fixedly connected to the lower part of the outer surface of the sheath near the connecting frame, which is inclined to support the lower surface of the measuring ruler. When the sheath moves away from the outer tube, the measuring ruler is pushed out by the elastic force of the third spring, so that the measuring ruler is at the lower part of the residual calcification plaque. The drive motor is started to drive the camera to rotate left and right. The thickness of the residual calcification plaque is measured by the camera in combination with the measuring ruler, which can effectively understand the thickness of the calcification plaque. Then, the laser cutting head is used to clean it, which can facilitate uniform cutting and ensure the treatment effect. Attached Figure Description

[0037] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

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

[0039] The device includes a rotating assembly, an adsorption assembly fixedly connected to the middle of the outer surface of the rotating assembly, a sliding groove 35 on the lower surface of the adsorption assembly, a first electromagnetic block 1 fixedly connected to both ends of the sliding groove 35, a sealing assembly slidably connected to the middle of the sliding groove 35, a second electromagnetic block 2 adsorbed on the lower surface of the sealing assembly, a gas supply assembly fixedly connected to the lower surface of the second electromagnetic block 2, a through groove on the outer surface of the gas supply assembly, a venting assembly fixedly connected inside the through groove, a protective sleeve 3 fitted onto the bottom of the outer surface of the rotating assembly, a laser cutting head 4 fixedly installed on the top of the outer surface of the protective sleeve 3, a measuring assembly connected to the middle of the outer surface of the protective sleeve 3, a detection assembly fixedly connected to the outer surface of the protective sleeve 3 below the measuring assembly, an outer tube 5 fitted onto the outer surface of the protective sleeve 3, an installation groove on the inner side wall of the outer tube 5, and a pushing assembly fixedly connected inside the installation groove.

[0040] The adsorption assembly includes a fan blade 9. The central rotating seat of the fan blade 9 is coaxially and fixedly connected to the outer surface of the drive shaft 6. Fixed frames 10 are fixedly connected to both the upper and lower ends of the central rotating seat of the fan blade 9. An airbag 11 is fixedly covered on the outer surface of the fixed frame 10. During the rotation assembly's grinding of calcified plaques, the fan blade 9 rotates synchronously with the drive shaft 6, creating a negative pressure state above the fan blade 9. This adsorbs the calcified plaques that have been ground down to the area below the fan blade 9, allowing for timely removal of the calcified plaques that have fallen down during grinding. This prevents the grinding wheel 7 from being affected and causing it to deviate from its track, thus affecting its use. Simultaneously, after grinding is completed, the airbag 11 is inflated, causing the edge of the airbag 11 to adhere tightly to the inner wall of the blood vessel. Combined with the sealing assembly, the fixed frame 10 is sealed, thus blocking the fallen calcified plaques below the fixed frame 10. This prevents the calcified plaques that have been ground down from floating to deeper blood vessels and affecting the purity of the blood vessels.

[0041] The sealing assembly includes a third electromagnetic block 12, the outer surface of which is slidably connected to the middle of the slide groove 35. A sealing bag 13 is fixedly connected to the lower surface of the third electromagnetic block 12, and a fourth electromagnetic block 14 is fixedly connected to the lower surface of the sealing bag 13. The sealing bag 13 is made of a completely sealed material. When the fan is running, the first electromagnetic block 1 inside the slide groove 35 is electrically charged and attracts the third electromagnetic block 12. The second electromagnetic block 2 and the fourth electromagnetic block 14 are simultaneously in a magnetic attraction state. At this time, the sealing bag 13 is in a contracted state and adheres to the outer surface of the drive shaft 6 to prevent it from intercepting the calcified plaques that fall off during the rotary grinding. After the rotary grinding is completed, the fan blade 9 stops rotating and charges the first electromagnetic block 1 outside the slide groove 35 to attract the third electromagnetic block 12, thereby causing the upper end of the sealing bag 13 to unfold and seal the lower surface of the fixing frame 10. This prevents the calcified plaques from floating to deeper blood vessels during the subsequent calcified plaque removal process, which could lead to new vascular stenosis or trigger acute thrombosis.

[0042] The air supply assembly includes a fixing ring 15, the upper surface of which is fixedly connected to the lower surface of the second electromagnetic block 2. A push rod 16 is fixedly connected to the lower surface of the fixing ring 15. A sealing ball 17 is fixedly connected to the bottom end of the push rod 16. A connecting rod 18 is snapped onto the outer surface of the sealing ball 17. A first spring 19 is fixedly connected to the upper surface of the connecting rod 18. An air tube 20 is fixedly connected to the top end of the outer surface of the connecting rod 18. An air supply airbag 21 is fixedly connected to the bottom end of the outer surface of the connecting rod 18. A force-bearing block 22 is fixedly connected to the bottom of the outer surface of the balloon 21. The force-bearing block 22 pushes the air supply balloon 21 to move upward, compressing the first spring 19. 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 balloon 21 floats up and enters the interior of the connecting rod 18. It then enters the interior of the balloon 11 through the trachea 20, inflating the interior of the balloon 11. This causes the outer periphery of the fixing frame 10 to fit tightly against the inner wall of the blood vessel, thereby sealing the area above the calcified plaque.

[0043] The venting assembly includes an air port 23. The outer surface of the air port 23 is fixedly connected to the inside of the through groove. A second spring 24 is fixedly connected to the back of the air port 23. A sealing plate 25 is fixedly connected to one end of the second spring 24. When the outer tube 5 is moved upward, the push ball 34 enters the air port 23 and pushes the sealing plate 25. The second spring 24 is stretched so that the sealing plate 25 moves away from the end of the air port 23, thereby venting the gas inside the air supply bag 21. This makes the air pressure inside the air supply bag 21 lower than the air pressure inside the air bag 11. When used in conjunction with the air supply assembly, the gas inside the air bag 11 can be vented, making it easier to remove the device from the body.

[0044] The push assembly includes a housing 32, the outer surface of which is fixedly connected to the inside of the mounting groove. A fourth spring 33 is fixedly connected to the inner bottom wall of the housing 32. A push ball 34 is fixedly connected to one end of the fourth spring 33. When the assembly is aligned with the venting assembly, the fourth spring 33 pushes the push ball 34, causing it to squeeze the sealing plate 25 away from the air port 23, thus venting the air.

[0045] The diameter of the outer tube 5 is larger than the diameter of the air supply bladder 21. The pushing assembly and the deflation assembly are compatible. The outer tube 5 can be moved to the periphery of the air supply bladder 21 so that the pushing assembly and the deflation assembly can be connected.

[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 around the outer periphery of the slide groove 35 generate magnetic attraction, the second electromagnetic block 2 moves away from the fourth electromagnetic block 14, causing the upper part of the sealing bag 13 to unfold and seal the lower surface of the fixing frame 10. When the first electromagnetic block 1 and the third electromagnetic block 12 around the inner periphery of the slide groove 35 generate magnetic attraction, the second electromagnetic block 2 and the fourth electromagnetic block 14 are simultaneously in a magnetic attraction state, causing the sealing bag 13 to be in a contracted state and tightly attached to the outer periphery of the drive shaft 6, so as to avoid affecting the adsorption of the calcified plaques under the rotary grinding by the fan blade 9.

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

[0048] The rotating assembly includes a hollow drive shaft 6. The middle of the outer surface of the drive shaft 6 is fixedly connected to the middle of the adsorption assembly. A coaxial grinding wheel 7 is fixedly connected to the top of the outer surface of the drive shaft 6. A guide wire 8 is sleeved in the middle of the drive shaft 6. The outer surface of the grinding wheel 7 is covered with abrasive, which can be selected as alumina, silicon carbide, or diamond to improve cutting efficiency. In actual operation, the drive shaft 6 extends out of the blood vessel and is connected to a high-frequency motor. Driven by the high-frequency motor and guided by the guide wire 8, the drive shaft 6 drives the grinding wheel 7 to rotate and move forward, rubbing against the calcified plaque. The hardness and sharpness of the abrasive enable it to effectively cut and remove calcified material, thereby opening the channel and facilitating the passage of the laser cutting head 4. This effectively avoids the problem of poor passage capacity for narrow lesions.

[0049] The measuring assembly includes a connecting frame 26. One side of the connecting frame 26 is fixedly connected to the middle of the outer surface of the sheath 3. The side of the connecting frame 26 away from the sheath 3 is rotatably connected to a measuring scale 27 via a rotating rod. A third spring 28 is fixedly connected to the lower surface of the measuring scale 27. Scale lines are provided on both the upper and lower sides of the measuring scale 27. One end of the third spring 28 is fixedly connected to the lower part of the outer surface of the sheath 3 near the connecting frame 26, and is inclined to support the lower surface of the measuring scale 27. When not in operation, the measuring assembly is limited by the outer tube 5, and the device is located inside the outer tube 5. When it is necessary to measure the calcified plaque, the sheath 3 is pushed forward, so that the front end of the sheath 3 is away from the outer tube 5. At this time, under the elastic force of the third spring 28, the measuring scale 27 is pushed out, so that the measuring scale 27 is located at the lower part of the residual calcified plaque, which facilitates the 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, located below the measuring component. A drive motor 30 is fixedly mounted on one side of the mounting bracket 29. A camera 31 is fixedly connected to the output end of the drive motor 30. When the drive motor 30 is started, the camera 31 rotates left and right. The camera 31 captures calcified plaques or captures the measurement scale of the measuring ruler 27. Combined with the measuring ruler 27, the thickness of the residual calcified plaques is measured, which facilitates an effective understanding of the thickness of the calcified plaques. Then, the laser cutting head 4 is used to clean them, which facilitates uniform cutting and ensures the treatment effect.

[0051] Working principle: First, the drive shaft 6 extends outward from the blood vessel and connects to a high-frequency motor. 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, grinding the calcified plaque. Simultaneously, the fan blade 9 rotates synchronously with the drive shaft 6, creating a negative pressure above the fan blade 9, thereby adsorbing the ground calcified plaque to the area below the fan blade 9. This allows for timely removal of the ground calcified plaque. Next, after the grinding wheel 7 rotates and passes through the closed calcified plaque, a channel is created in the middle of the calcified plaque, driving the fixing frame 10 to pass through the calcified plaque simultaneously. The sealing bag 13 is made of a completely sealed material. When the fan moves, the first... Electromagnetic block 1 is electrically charged and attracts the third electromagnetic block 12. The second electromagnetic block 2 and the fourth electromagnetic block 14 are simultaneously in a magnetic attraction state. 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 rotator grinding. After rotator grinding is completed, the fan blade 9 stops rotating and charges the first electromagnetic block 1 on the outside of the slide groove 35, causing the first electromagnetic block 1 on the outside of the slide groove 35 to magnetically attract the third electromagnetic block 12. The second electromagnetic block 2 moves away from the fourth electromagnetic block 14, thereby causing the upper end of the sealing bag 13 to unfold and seal the lower surface of the fixing frame 10. Then, the air supply bag 21 is pushed upward, compressing the first spring 19 and pushing it upward. Rod 16 pushes the sealing ball 17 downward, causing it to move away from the connecting rod 18. Gas inside the air supply bladder 21 rises and enters the connecting rod 18, then through the trachea 20 into the air bladder 11, inflating it. This causes the outer periphery of the fixing frame 10 to fit tightly against the inner wall of the blood vessel. Next, one end of the third spring 28 is fixedly connected to the outer surface of the sheath 3 near the lower part of the connecting frame 26, providing inclined support to the lower surface of the measuring scale 27. When the sheath 3 moves away from the outer tube 5, the elastic force of the third spring 28 pushes the measuring scale 27 out, positioning it at the lower periphery of the residual calcified plaque. The drive motor 30 is then activated to move the camera. The device rotates left and right, and the thickness of the residual calcification plaque is measured by the camera 31 and the measuring ruler 27. This allows for an effective understanding of the thickness of the calcification plaque, which is then cleaned by the laser cutting head 4. Finally, the outer tube 5 is moved upward, allowing the push ball 34 to enter the air port 23. The fourth spring 33 pushes the push ball 34, causing it to squeeze the sealing plate 25. The second spring 24 stretches, causing the sealing plate 25 to move away from the end of the air port 23, thereby expelling the gas inside the air supply bag 21. This makes the air pressure inside the air supply bag 21 lower than the air pressure inside the air bag 11. When used in conjunction with the air supply assembly, the gas inside the air bag 11 can be expelled, making it easier to remove the device from the body.

According to the perspective of the observer, the side of the device facing the observer is defined as front, the left side of the observer is defined as left, and so on.
