Abstract
Description
A device for resecting atherosclerosis Technical Field
[0001] This invention belongs to the field of medical device technology, specifically an arteriosclerosis resection device. Background Technology
[0002] Atherosclerosis is a common cardiovascular disease characterized by the formation of fatty deposits (called plaques) in the arterial walls, leading to narrowing and hardening of the arteries. This pathological change affects blood flow and increases the risk of heart disease, stroke, and other cardiovascular events. Currently, in addition to drug treatment, the removal of atherosclerotic plaques can also be achieved through vascular imaging guidance using rotary cutting and grinding devices to cut or grind the atherosclerotic plaques from the blood vessel walls and remove them from the body through catheters.
[0003] A Chinese invention patent, CN 116350313 A, discloses an atherosclerosis resection device. The key technical points are: it includes a catheter, a cutting element, and an optical fiber; the catheter is connected to the cutting element and is used to drive the cutting element to rotate axially for cutting; the optical fiber is disposed in the catheter and connected to the cutting element, and is used to emit and receive light signals during the rotation of the cutting element. The cutting element performs rotary cutting under the drive of the catheter, which can effectively cut plaques within the blood vessel; while the optical fiber emits near-infrared light during rotation and collects light signals reflected or scattered by the blood vessel wall, thereby completing intravascular optical coherence tomography imaging. The imaging is clear and accurate, thus realizing arterial plaque rotary resection surgery under real-time visualization, improving... While performing arterial plaque excision surgery under real-time visualization significantly improves the maneuverability of the procedure and reduces the risk of damage to normal areas caused by the cutting motion of the cutting tool, the direct discharge of the arterial plaque through a catheter after it has been ground up makes it difficult to collect in a sealed manner. Without collecting plaque samples, the opportunity to analyze the composition and properties of the plaque is lost, limiting the understanding of the mechanism of atherosclerosis. Without samples for subsequent analysis, doctors cannot assess the effectiveness of treatment and changes in the plaque, which may lead to untimely adjustments to the treatment plan.

[0016] The beneficial effects of this invention are as follows:
[0017] 1. The atherosclerosis resection device of the present invention, through a set collection component, after the arterial plaque is crushed, needs to be removed from the blood vessel. After removal, the arterial plaque is placed in the collection component. The components in the collection component can filter the arterial plaque and perform dry-wet separation. The separated arterial plaque can be subjected to more detailed pathological and biochemical analysis to help understand the composition and characteristics of the plaque. By crushing the plaque and sealing it for collection, damage to surrounding tissues during the operation can be reduced, the risk of bleeding and other complications can be reduced, and the plaque can be effectively removed and analyzed. This can reduce the risk of heart attack and stroke and improve the long-term prognosis of patients.

The atherosclerosis resection device of the present invention, through the set clamping component, requires the resection device to be punctured into the blood vessel during the resection of arterial plaques. The clamping component clamps the blood vessel, which can effectively reduce blood flow in the surgical area, thereby reducing the risk of bleeding and facilitating the operation of the surgeon. Clamping the blood vessel can reduce the formation of postoperative hematoma and reduce the incidence of complications. In addition, in the clamped state, the surgeon can more accurately remove the atherosclerotic plaques and ensure the maximum removal of diseased tissue.
[0019] 3. The atherosclerosis resection device of the present invention, through the set scraping component, uses the rotary cutting component to break up the arterial plaque, and the arterial plaque will remain in the blood vessel. The scraping component is quickly inflated and closely adheres to the inner wall of the blood vessel to scrape off the remaining arterial plaque, thus completely removing the plaque. This can slow down the progression of atherosclerosis and reduce the risk of future cardiovascular events.
[0020] 4. The atherosclerosis resection device of the present invention, through the set probe component, requires the use of the probe component to view the inside of the blood vessel when removing arterial plaque. The probe component can adjust the angle of the endoscopic camera according to the required viewing angle, so as to see more clearly. The use of the probe device significantly improves the visualization and accuracy of the operation, reduces the risk of complications, and improves the postoperative recovery of patients. Through real-time monitoring and dynamic observation, surgeons can complete the operation more safely and effectively. Attached Figure Description

[0034] 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.
[0035] Referring to Figures 1-11, the present invention provides two technical solutions:
[0036] Example 1:
[0037] An atherosclerosis resection device includes a puncture cannula 1, an outer shell 2 connected to the inside of the puncture cannula 1, an A connecting tube 3 fixedly connected to one end of the outer shell 2, an opening on the outer surface of the A connecting tube 3 for fixing a sleeve 4, a collecting component connected to the inside of the sleeve 4, a B connecting tube 5 fixedly connected to one end of the A connecting tube 3, a clamping component fixedly connected to the outer surface of the B connecting tube 5, a rotating component fixedly connected inside the B connecting tube 5, a shock-absorbing component fixedly connected to one end of the rotating component, a rotary cutting component fixedly connected to one end of the rotary cutting component, a scraping component fixedly connected to one end of the scraping component, and a probing component fixedly connected to one end of the scraping component.
[0038] The collection component includes a collection tube 6, the outer surface of which is threaded to the inside of a sleeve 4. A filter screen 7 is fixedly connected inside the collection tube 6. A sleeve 8 is fixedly connected to the outer surface of the collection tube 6. A spring A 9 is fixedly connected inside the sleeve 8. A telescopic rod 10 is fixedly connected to one end of the spring A 9. A push-pull block 11 is fixedly connected to the outer surface of the telescopic rod 10. An L-shaped groove for sliding the push-pull block 11 is opened on the outer surface of the sleeve 8. A soft shell ring 12 is fixedly connected to one end of the telescopic rod 10. An A groove for fixing and installing a steel ring 13 is opened inside the soft shell ring 12. A sealing cover 14 is fixedly connected to the inner side wall of the soft shell ring 12. A drainage tube 15 is fixedly connected to the bottom of the collection tube 6.
[0039] Example 2:
[0040] Based on Embodiment 1: The clamping component includes a connecting block 16. The inner sidewall of the connecting block 16 is fixedly connected to the outer surface of the B connecting tube 5. Both sides of the bottom of the connecting block 16 are fixedly connected to the A connecting rod 17. The bottom of the A connecting rod 17 is fixedly connected to the support frame 18. The upper surface of the support frame 18 is fixedly connected to the box 19. The A micro electric push rod 20 is fixedly installed inside the box 19. One end of the A micro electric push rod 20 is fixedly connected to the push rod 21. Both ends of the outer surface of the push rod 21 are sleeved with the connecting frame 22. The front of the connecting frame 22 is rotatably connected to the clamping rod 24 through the A rotating rod 23. One end of the clamping rod 24 is fixedly connected to the clamping rod 24. The back of the holding piece 25 and the connecting frame 22 are rotatably connected to the back of the support frame 18 via the B rotating rod 53. Both ends of the support frame 18 are provided with B grooves, and the inside of the B grooves is inserted into the outer surface of the clamping rod 24. When removing arterial plaques, the resection device needs to be punctured into the blood vessel, and the blood vessel is clamped by the clamping assembly. Clamping the blood vessel can effectively reduce blood flow in the surgical area, thereby reducing the risk of bleeding and making it easier for the surgeon to operate. Clamping the blood vessel can reduce the formation of postoperative hematoma and reduce the incidence of complications. In addition, in the clamped state, the surgeon can more accurately remove atherosclerotic plaques and ensure maximum removal of diseased tissue.
[0041] The rotating component includes a micro drive motor 52. The outer surface of the micro drive motor 52 is fixedly connected to the inside of the B connecting tube 5. The output end of the micro drive motor 52 is splinedly connected to the B micro electric push rod 26. When the micro drive motor 52 rotates, it drives the B micro electric push rod 26 to rotate. The high-speed rotation drives the rotary cutting component to cut the arterial plaque.
[0042] The damping component A connecting sleeve 27 has one end fixedly connected to one end of B miniature electric push rod 26. A damping pad 28 is fixedly connected inside A connecting sleeve 27. A spring 29 is fixedly connected to the surface of A damping pad 28. A damping rod 30 is inserted inside spring 29. One end of spring 29 is fixedly connected to B damping pad 31. A connecting sleeve 32 is fixedly connected to the outer surface of B damping pad 31. To reduce the force of rotational vibration, the damping rod 30 and spring 29 work together. Spring 29 is compressed within A damping pad 28 and B damping pad 31, and then within A connecting sleeve 27 and B connecting sleeve 32. When external force acts on the system, spring 29 is compressed or stretched, storing energy. When the force disappears, spring 29 returns to its original shape, releasing the stored energy. The damping rod 30 consumes the energy released by spring 29, reducing the amplitude of vibration. It converts kinetic energy into heat energy through fluid friction or other resistance mechanisms, thereby reducing vibration.
[0043] The rotary cutting component includes a rotary cutting blade 33. One end of the rotary cutting blade 33 is fixedly connected to one end of the B connecting sleeve 32, and the other end of the rotary cutting blade 33 is fixedly connected to a B connecting rod 34. A rotating plate 35 is fixedly connected to the outer surface of the B connecting rod 34, and a bearing 36 is fixedly connected to one end of the B connecting rod 34. A micro drive motor 52 drives the rotary cutting blade 33 to rotate, and the blade inside the rotary cutting blade 33 breaks up the arterial plaque in the blood vessel under the force of rotation.
[0044] The scraping component includes a miniature air pump 37, one end of which is fixedly connected to the outer surface of the bearing 36. An air bag 38 is fixedly connected to the output end of the miniature air pump 37. After the arterial plaque is broken up by the rotary cutting component, the arterial plaque will remain in the blood vessel. The scraping component is quickly inflated and pressed against the inner wall of the blood vessel. During the retraction process, the miniature electric push rod 26 scrapes off the remaining arterial plaque, thoroughly removing the plaque. This can slow the progression of atherosclerosis and reduce the risk of future cardiovascular events.
[0045] The probe component includes a C-shaped miniature electric push rod 39, with A-shaped adjustment blocks 40 fixedly connected to both ends of the C-shaped miniature electric push rod 39. One side of the A-shaped adjustment block 40 is rotatably connected to an A-shaped adjustment plate 42 via an A-shaped rotating rod 41. One end of one of the A-shaped adjustment plates 42 is fixedly connected to a connecting plate 43. The back of the connecting plate 43 is fixedly connected to one end of an airbag 38. A B-shaped adjustment block 44 is fixedly connected to the bottom of the front of the connecting plate 43. One side of the B-shaped adjustment block 44 is rotatably connected to a B-shaped adjustment plate 46 via a B-shaped rotating rod 45. One end of the B-shaped adjustment plate 46 is fixedly connected to an endoscope camera 47. When removing arterial plaques, the probe component is used to view the inside of the blood vessel. The probe component can adjust the angle of the endoscope camera 47 according to the required viewing angle, allowing for a clearer view. The use of the probe device significantly improves the visualization and precision of the surgery, reduces the risk of complications, and improves the patient's postoperative recovery. Through real-time monitoring and dynamic observation, surgeons can complete the surgery more safely and effectively.
[0046] The inner thread of the outer shell 2 is connected to a connector 48, which is tapered in shape. The tapered shape of the connector 48 facilitates entry into the blood vessel for atherosclerosis resection.
[0047] One end of the B connecting pipe 5 is fixedly connected to a connecting cover 49. One end of the back of the connecting cover 49 has an A-hole groove for fixing and installing the A button 50, and the other end of the back of the connecting cover 49 has a B-hole groove for fixing and installing the B button 51. The A button 50 is used to control the B micro electric push rod 26, and the B button 51 is used to control the micro air pump 37.
[0048] Working principle: The outer shell 2 is screwed into the puncture cannula 1, allowing it to be inserted into the blood vessel along with the puncture cannula 1. After the puncture cannula 1 is inserted into the blood vessel, the vessel needs to be clamped. The A micro electric push rod 20 is activated, driving the push rod 21 up and down. As the push rod 21 moves up and down, the B rotating rod 53 rotates, causing the connecting frame 22 to slide left and right on the push rod 21. As the connecting frame 22 slides, it causes the A rotating rod 23 and the clamping rod 24 to move left and right. The clamping rod 24 slides left and right within the B grooves at both ends of the support frame 18, causing the clamping pieces 25 to clamp the vessel left and right. Clamping the vessel effectively reduces blood flow to the surgical area, thereby reducing the risk of bleeding and facilitating the surgeon's operation. Then, press... Button A 50 controls miniature electric actuator B 26, which extends and retracts, causing the shock-absorbing component, slicing component, scraping component, and imaging component to extend and retract into the blood vessel. Endoscopic camera 47 is used to examine the internal arterial plaque. When the angle of endoscopic camera 47 needs adjustment, miniature electric actuator C 39 is activated. The extension and retraction of miniature electric actuator C 39 rotates adjustment block A 40 and adjustment plate A 42. While adjustment block A 40 and adjustment plate A 42 rotate, adjustment block B 44 and adjustment plate B 46 rotate, allowing endoscopic camera 47 to tilt up and down for easier viewing. Subsequently, miniature drive motor 52 is activated, which drives miniature electric actuator B. 26. During rotation, to reduce the force of rotational vibration, damping rod 30 and spring 29 work together. Spring 29 is compressed into damping pads 28 and 31, and then into connecting sleeves 27 and 32. When external force is applied to the system, spring 29 is compressed or stretched, storing energy. When the force disappears, spring 29 returns to its original shape, releasing the stored energy. Damping rod 30 consumes the energy released by spring 29, reducing the amplitude of vibration. It converts kinetic energy into heat energy through fluid friction or other resistance mechanisms, thereby reducing vibration. Micro drive motor 52 drives rotary cutting blade 33 to rotate. The blades inside rotary cutting blade 33 break up arterial plaques in the blood vessels under the force of rotation, thus breaking up the arteries. After the plaque is broken up, press button B 51. Button B 51 controls the micro air pump 37, which inflates the air bag 38. The air bag 38 is pressed tightly against the inner wall of the blood vessel, activating the micro electric push rod B 26. When the micro electric push rod B 26 retracts, it uses the rotating plate 35 and the air bag 38 to carry out the broken arterial plaque. When it reaches the connecting tube A 3, it falls into the sleeve 4 and then into the collection tube 6. The collection tube 6 contains a filter screen 7, which separates the arterial plaque into wet and dry parts. The blood flows into the drainage tube 15, and the solid plaque falls onto the filter screen 7. When it is necessary to remove the arterial plaque for research, press the push-pull block 11. The push-pull block 11 moves within the L-shaped groove on the sleeve 8, causing the telescopic rod 10 to move backward. When the telescopic rod 10 moves backward...The spring 9 extends and retracts within the sleeve 8, causing the telescopic rod 10 to cause the steel ring 13 inside the soft shell ring 12 to spring back. The steel ring 13 springs back to its circular shape, covering the sealing cover 14 inside the collection tube 6, achieving a sealing effect. The collection tube 6 is then unscrewed from the sleeve 4, and the arterial plaque is removed. Sealed collection can reduce damage to surrounding tissues during surgery, reduce the risk of bleeding and other complications, effectively remove plaque for subsequent analysis, reduce the risk of heart attack and stroke, and improve the patient's long-term prognosis.
