Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, in particular to an atherosclerosis removal device. Background Art

[0002] Atherosclerosis is a common cardiovascular disease characterized by the formation of fatty deposits (called plaques) in the arterial walls, which leads to narrowing and hardening of the arteries. This pathological change can affect blood flow and increase 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 the guidance of vascular imaging, using rotary cutting and grinding devices to cut or grind atherosclerotic plaques from the blood vessel walls and expel them from the body through a catheter.

[0003] A Chinese invention patent publication number CN 116350313 A discloses an atherosclerosis removal device, the technical solution of which is as follows: it includes a catheter, a cutting piece and an optical fiber; the catheter is connected to the cutting piece and is used to drive the cutting piece to rotate axially for cutting; the optical fiber is arranged in the catheter and connected to the cutting piece, and the optical fiber is used to emit and receive optical signals during the rotation of the cutting piece. The cutting piece is driven by the catheter to perform rotary cutting, which can effectively cut the plaque in the blood vessel; and the optical fiber emits near-infrared light during the rotation process and collects the optical signals reflected or scattered by the blood vessel wall, so as to complete the intravascular optical coherence tomography imaging, and the imaging is clear and accurate, thereby realizing the arterial plaque rotary cutting surgery under real-time visual conditions, which improves the quality of life. The controllability of the atherectomy surgery is improved, and the risk of damage to normal parts caused by the atherectomy action of the cutting piece is significantly reduced. Although the atherectomy surgery is performed under real-time visual conditions, the controllability of the atherectomy surgery is improved, and the risk of damage to normal parts caused by the atherectomy action of the cutting piece is significantly reduced, but after the arterial plaque is ground up and expelled from the body using a catheter, the arterial plaque is directly expelled from the body, which is not convenient for sealing and collection. Failure to collect plaque samples will lose the opportunity to analyze the composition and properties of the plaque, limiting the understanding of the mechanism of atherosclerosis. Without samples for subsequent analysis, doctors cannot evaluate the effectiveness of the treatment and changes in the plaque, which may lead to untimely adjustment of the treatment plan.

[0004] To this end, the present invention provides an atherosclerosis removal device. Summary of the invention

One end of the telescopic rod 10 is fixedly connected to a soft shell ring 12. An A groove for fixedly installing a steel ring 13 is provided 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 pipe 15 is fixedly connected to the bottom of the collecting pipe 6.

[0039] Embodiment 2:

[0040] On the basis of Embodiment 1: The clamping member includes a connecting block 16. The inner side wall of the connecting block 16 is fixedly connected to the outer surface of the B connecting pipe 5. On both sides of the bottom of the connecting block 16, A connecting rods 17 are fixedly connected. The bottom of the A connecting rods 17 is fixedly connected to a support frame 18. The upper surface of the support frame 18 is fixedly connected to a box body 19. Inside the box body 19, a micro electric push rod A 20 is fixedly installed. One end of the micro electric push rod A 20 is fixedly connected to a push rod 21. Connecting frames 22 are sleeved on both ends of the outer surface of the push rod 21. The front of the connecting frame 22 is rotatably connected to a clamping rod 24 through an A rotating rod 23. One end of the clamping rod 24 is fixedly connected to a clamping piece 25. The back of the connecting frame 22 is rotatably connected to the back of the support frame 18 through a B rotating rod 53. B grooves are opened at both ends of the support frame 18. The inside of the B grooves is inserted into the outer surface of the clamping rod 24. When excising arterial plaques, it is necessary to puncture the excision device into the blood vessel and use the clamping assembly to clamp the blood vessel. Clamping the blood vessel can effectively reduce the blood flow in the surgical area, thereby reducing the bleeding risk and facilitating the operation of the surgeon. Clamping the blood vessel can reduce the formation of postoperative hematoma and the incidence of complications. In addition, in the clamped state, the surgeon can more precisely excise atherosclerotic plaques to ensure the maximum removal of diseased tissues.

[0041] The rotating member 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 pipe 5. The output end of the micro drive motor 52 is spline-connected to a micro electric push rod B 26. When the micro drive motor 52 rotates, it drives the rotation of the micro electric push rod B 26 inside, and the high-speed rotation drives the rotary cutting member to rotary cut the arterial plaque.

[0042] The shock-absorbing member is an A connecting sleeve 27. One end of the A connecting sleeve 27 is fixedly connected to one end of the micro electric push rod B 26. An A shock-absorbing pad 28 is fixedly connected inside the A connecting sleeve 27. A B spring 29 is fixedly connected to the surface of the A shock-absorbing pad 28. A damping rod 30 is inserted into the inside of the B spring 29. One end of the B spring 29 is fixedly connected to a B shock-absorbing pad 31. The outer surface of the B shock-absorbing pad 31 is fixedly connected to a B connecting sleeve 32. To reduce the intensity of rotational vibration, the damping rod 30 and the B spring 29 are used in combination. The B spring 29 is squeezed between the A shock-absorbing pad 28 and the B shock-absorbing pad 31, and then squeezed inside the A connecting sleeve 27 and the B connecting sleeve 32. When an external force acts on the system, the B spring 29 will be compressed or stretched to store energy. When the force disappears, the B spring 29 will return to its original shape and release the stored energy. The damping rod 30 consumes the energy released by the B spring 29 and slows down 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 member 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. The other end of the rotary cutting blade 33 is fixedly connected to a B connecting rod 34. A rotary piece 35 is fixedly connected to the outer surface of the B connecting rod 34. One end of the B connecting rod 34 is fixedly connected to a bearing 36. The 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 rotational force.

[0044] The scraping member includes a micro air pump 37. One end of the micro air pump 37 is fixedly connected to the outer surface of the bearing 36. The output end of the micro air pump 37 is fixedly connected to an airbag 38. After the arterial plaque is broken up by the rotary cutting member, the arterial plaque will remain in the blood vessel. The scraping assembly is quickly inflated to closely adhere to the inner wall of the blood vessel. During the retraction process of the B micro electric push rod 26, the remaining arterial plaque is scraped off, completely removing the plaque, which can slow down the progression of atherosclerosis and reduce the risk of future cardiovascular events.

[0045] The searchlight member includes a C micro electric push rod 39. Both ends of the C micro electric push rod 39 are fixedly connected to an A adjusting block 40. One side of the A adjusting block 40 is rotatably connected to an A adjusting piece 42 through an A rotating rod 41. One end of one of the A adjusting pieces 42 is fixedly connected to a connecting disc 43. The back of the connecting disc 43 is fixedly connected to one end of the airbag 38. The bottom of the front of the connecting disc 43 is fixedly connected to a B adjusting block 44. One side of the B adjusting block 44 is rotatably connected to a B adjusting piece 46 through a B rotating rod 45. One end of the B adjusting piece 46 is fixedly connected to an endoscope camera 47. When removing arterial plaque, it is necessary to use the searchlight member to search inside the blood vessel. The searchlight member can adjust the angle of the endoscope camera 47 according to the viewing angle required, enabling a clearer view. The use of the searchlight device significantly improves the visualization and accuracy of the operation, reduces the risk of complications, and improves the postoperative recovery of the patient. Through real-time monitoring and dynamic observation, the surgeon can complete the operation more safely and effectively.

[0046] A connector 48 is threadedly connected inside the housing 2. The shape of the connector 48 is conical. The conical shape of the connector 48 facilitates entry into the blood vessel for atherosclerotic resection.

[0047] One end of the B connecting pipe 5 is fixedly connected to a connecting cover 49. An A hole for fixedly installing the A button 50 is provided at one end of the back of the connecting cover 49, and a B hole for fixedly installing the B button 51 is provided at the other end of the back of the connecting cover 49. 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: Screw the outer shell 2 into the puncture cannula 1. The outer shell 2 can be punctured into the blood vessel together with the puncture cannula 1. After the puncture cannula 1 is punctured into the blood vessel, the blood vessel needs to be clamped. Start the A micro electric push rod 20. The A micro electric push rod 20 drives the push rod 21 to push up and down. When the push rod 21 is pushed up and down, the B rotating rod 53 rotates to drive the connecting frame 22 to slide left and right on the push rod 21. When the connecting frame 22 slides, it drives the A rotating rod 23 and the clamping rod 24 to move left and right. The clamping rod 24 slides left and right in the B grooves at both ends of the support frame 18, driving the clamping pieces 25 to clamp left and right, clamping the blood vessel. Clamping the blood vessel can effectively reduce the blood flow in the surgical area, thereby reducing the bleeding risk and facilitating the operation of the surgeon. Subsequently, press the A button 50. The A button 50 controls the B micro electric push rod 26. The B micro electric push rod 26 extends and retracts back and forth, driving the shock-absorbing component, the rotary cutting component, the scraping component and the searchlight component to extend into the blood vessel. Use the endoscope camera 47 to searchlight inside the blood vessel to observe the condition of the internal arterial plaque. When it is necessary to adjust the angle of the endoscope camera 47, start the C micro electric push rod 39. When the C micro electric push rod 39 extends and retracts back and forth, it drives the A adjusting block 40 and the A adjusting piece 42 to rotate. When the A adjusting block 40 and the A adjusting piece 42 rotate, the B adjusting block 44 and the B adjusting piece 46 rotate back and forth, which can drive the endoscope camera 47 to tilt up and down, changing the angle for easy viewing. Subsequently, start the micro drive motor 52. The micro drive motor 52 drives the B micro electric push rod 26 to rotate. When rotating, to reduce the intensity of the rotational vibration, the damping rod 30 and the B spring 29 are used in combination. The B spring 29 is squeezed between the A shock pad 28 and the B shock pad 31, and then squeezed into the A connecting sleeve 27 and the B connecting sleeve 32. When an external force acts on the system, the B spring 29 will be compressed or stretched to store energy. When the force disappears, the B spring 29 will return to its original shape and release the stored energy. The damping rod 30 consumes the energy released by the B spring 29 and slows down the amplitude of the vibration. It converts kinetic energy into heat energy through fluid friction or other resistance mechanisms, thereby reducing vibration. The micro drive motor 52 drives the rotary cutting blade 33 to rotate. The blades inside the rotary cutting blade 33 break up the arterial plaque in the blood vessel under the rotational force. After the arterial plaque is broken up, press the B button 51. The B button 51 controls the micro air pump 37. The micro air pump 37 inflates the airbag 38. The airbag 38 adheres tightly to the inner wall of the blood vessel. Start the B micro electric push rod 26. When the B micro electric push rod 26 retracts, the broken arterial plaque is carried out by the rotating piece 35 and the airbag 38. When it drives to the A connecting pipe 3, it falls into the sleeve 4 and then into the collection pipe 6 from the sleeve 4. There is a filter screen 7 in the collection pipe 6. The filter screen 7 is used to separate the arterial plaque into dry and wet states. The blood flows into the drainage pipe 15, and the solid plaque falls on the filter screen 7. When it is necessary to take out the arterial plaque for research, press the push-pull block 11, move the push-pull block 11 in the L-shaped chute on the sleeve 8, drive the telescopic rod 10 backward. When the telescopic rod 10 moves backward,Drive the A spring 9 to expand and contract within the sleeve 8. The telescopic rod 10 drives the steel ring 13 inside the soft shell ring 12 to rebound. The steel ring 13 rebounds to a ring shape, blocking the sealing cover 14 within the collection tube 6 to achieve a sealing effect. Unscrew the collection tube 6 from the sleeve 4 and take out the arterial plaque. Sealed collection can reduce damage to surrounding tissues during the operation, reduce the risk of bleeding and other complications, effectively remove the plaque and conduct subsequent analysis, reduce the risk of heart attack and stroke, and improve the long-term prognosis of the patient.
