Description

Technical Field

[0001] This invention relates to the field of endoscopic equipment, and in particular to a cerebrovascular endoscopy device. Background Technology

[0002] Endoscopic cerebral blood vessels are a new technology that combines neurointerventional and endoscopic techniques to observe or treat cerebrovascular diseases. It involves inserting a probe into the target blood vessel via a catheter through radial or femoral artery puncture, obtaining real-time color images of the vascular intima and blood flow. This technology is suitable for the diagnosis and treatment of cerebral vascular stenosis, aneurysms, and arteriovenous malformations. It is also suitable for pre-implantation of endoscopic cerebral blood vessels for real-time imaging during routine neurosurgical brain tumor surgery when the tumor includes blood vessels, thus avoiding damage to blood vessels and potential massive hemorrhage. Compared to traditional neurointerventional surgery, it also features minimal invasiveness and offers the advantage of reducing the use of digital subtraction angiography systems, thus reducing radiation exposure for surgical personnel.

[0003] Most existing cerebrovascular endoscopy devices only have the function of observing blood vessels. When encountering some vascular blockages, such as cholesterol deposits, they cannot clear the blockage. Therefore, this invention proposes a cerebrovascular endoscopy device. Summary of the Invention

[0004] To address the problems in the existing technology, this invention proposes a cerebral vascular endoscopy device, which solves the problem that most existing cerebral vascular endoscopy devices only have the function of vascular observation and cannot clear some vascular blockages, such as cholesterol deposits.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This invention proposes a cerebral vascular endoscopy device, including a first tube, a probe at one end of the first tube, a control box at the other end of the first tube, the probe and the control box being electrically connected, two adjustment devices on the outside of the first tube, a thin wire between the two adjustment devices, and a drive device on the first tube, which cooperates with the two adjustment devices.

[0007] Furthermore, the first tube is provided with a first airbag ring and a second airbag ring on its outside, and both the adjustment device and the drive device are located between the first airbag ring and the second airbag ring.

[0008] Furthermore, each of the adjusting devices includes a first ring and a second ring. The first ring is rotatably connected to the first tube, and the second ring is movably connected to the first tube. The two second rings are located on opposite sides of the two first rings. Each first ring is rotatably connected to a first rod, and each second ring is rotatably connected to a second rod. The first rod and the second rod are rotatably connected, and the thin wire is located between the two first rods.

[0009] Furthermore, the fine thread includes a first filament and a second filament. The first filament is rotatably connected to a first rod, and the second filament is rotatably connected to another first rod. One end of the second filament has a filament hole, and one end of the first filament is located in the filament hole. The first filament can be stored in the second filament.

[0010] Furthermore, the driving device includes an internal gear, which is sleeved on the outside of the first tube and rotatably connected to the first tube. A groove is provided on the first tube, and a first gear is provided in the groove. The first gear meshes with the internal gear. A first column is fixedly connected to the side of the internal gear near the adjusting device. One end of the first column passes through the first ring and the second ring. The first column is fixedly connected to both the first ring and the second ring.

[0011] The beneficial effects of this invention are:

[0012] This invention solves the problem that most existing cerebral vascular endoscopy devices only have the function of vascular observation, and cannot clear some vascular blockages, such as cholesterol deposits.

[0013] 1. When a blockage is detected in a blood vessel, such as in an area with high cholesterol deposits, the blockage is positioned between two regulating devices. An air-blowing device inflates the first and second airbag rings, sealing the blocked section of the blood vessel. Then, the drive motor and control device are activated. The drive motor's output shaft rotates, causing the rotating column to rotate. This rotation drives the first gear, which in turn drives the internal gear. The internal gear then rotates the first column and the two regulating devices, which in turn rotate the thin thread. The thin thread cleans the deposits in the blocked section, thus achieving the purpose of cleaning the deposits on the inner wall of the blocked section of the blood vessel.

[0014] 2. The control device can control the two electromagnets in each adjustment device to generate opposite magnetic fields and control the magnitude of the magnetic force generated by the electromagnets, so that the two electromagnets in each adjustment device can approach each other. At this time, the spring is compressed, thereby causing the first ring and the second ring to approach each other. The control device controls the distance between the two electromagnets by controlling the magnitude of the magnetic force, so that the thin wire slowly moves away from the first tube and slowly approaches the deposit. This achieves the purpose of making the volume of the deposit cleaned by the thin wire small, so that it can be easily absorbed through the absorption hole. At the same time, it also achieves the purpose of thoroughly cleaning the deposits in blood vessels of different sizes. Attached Figure Description

A drive motor 37 is fixedly connected in the fixed tube 36. One end of the rotating column 45 extends into the fixed tube 36 and is fixedly connected to the output shaft of the drive motor 37.

[0039] The outer side of the first tube 7 is provided with a first annular groove 30. The inner ring of the first airbag ring 2 is fixedly connected with a first soft sleeve 28.

The blower device 32 is existing technology. The blower device 32 can blow gas into the first airbag ring 2 and the second airbag ring 6 through the first air tube 33 and the second air tube 43, so that the first airbag ring 2 and the second airbag ring 6 become larger, thereby achieving the purpose of sealing the middle section of the blood vessel. Example 5

[0042] Based on embodiment 4, the first tube 7 is provided with a water outlet 10 and an absorption hole 11. The water outlet 10 and the absorption hole 11 are both located between the two adjusting devices 4. The water outlet 10 and the absorption hole 11 both extend to the other end of the first tube 7. The side of the fixing plate 38 away from the probe 1 is fixedly connected to the absorption device 35 and the water inlet device 41. The absorption device 35 is connected to the absorption hole 11 at the end of the first tube 7 through the absorption pipe 34. The water inlet device 41 is connected to the water outlet 10 at the end of the first tube 7 through the water inlet pipe 42.

[0043] The absorption device 35 can draw the solution from the absorption hole 11. It is an existing device. For example, a simple absorption device 35 includes an injection tube. The push end of the injection tube is fixedly connected to an electric push rod. By retracting the electric push rod, the end of the injection tube can generate suction, thereby drawing the solution from the absorption hole 11.

[0044] The water inlet device 41 can squeeze the cleaning fluid out of the water outlet 10. It is an existing device. For example, a simple water inlet device 41 includes an injection tube. The push end of the injection tube is fixedly connected to an electric push rod. By retracting the electric push rod, the cleaning fluid in the injection tube can be pushed out of the water outlet 10. Its function here is to clean the inside of the closed segment of the blood vessel. Example 6

[0045] Based on embodiment 5, a cleaning brush 9 is fixedly connected to one side of the first column 16. The cleaning brush 9 is in contact with the outside of the first pipe 7. The cleaning brush 9 is located above the water outlet 10 and the absorption hole 11. The cleaning brush 9 cooperates with the water outlet 10 and the absorption hole 11 to clean the water outlet 10 and the absorption hole 11.

[0046] Working principle: Through arterial puncture, the first tube 7 is implanted into the human vascular system. The probe 1 emits laser pulses and receives photoacoustic echo signals. The signal receiving device 39 can receive the signals collected by the probe 1 through the wire 40 and transmit the signals to the processor. The processor then reconstructs the photoacoustic and ultrasound images of the tissue through a certain imaging algorithm and displays them on the monitor. By observing the internal condition of the blood vessels in this way, the intraluminal structure of the blood vessels can be directly visualized, which makes up for the shortcomings of traditional neurointerventional surgery, which can only observe the external structure of the blood vessels.

[0047] When a blockage is detected in a blood vessel, such as in an area with high cholesterol deposits, the blockage is positioned between the two regulating devices 4. The inflator 32 inflates the first airbag ring 2 and the second airbag ring 6, sealing the blockage. Then, the drive motor 37 and control device are activated. The output shaft of the drive motor 37 rotates, causing the rotating column 45 to rotate. The rotating column 45 rotates, causing the first gear 46 to rotate. The first gear 46 rotates, causing the internal gear 17 to rotate. The internal gear 17 rotates, causing the first column 16 and the two regulating devices 4 to rotate. The two regulating devices 4 rotate, causing the thin thread 3 to rotate. The thin thread 3 cleans the deposits in the blockage, thus achieving the purpose of cleaning the deposits on the inner wall of the blocked blood vessel.

[0048] The control device can control the two electromagnets 21 in each adjustment device 4 to generate opposite magnetism and control the magnitude of the magnetic force generated by the electromagnets 21, so that the two electromagnets 21 in each adjustment device 4 can approach each other. At this time, the spring 19 is compressed, so that the first ring 12 and the second ring 15 approach each other. The control device can control the distance between the two electromagnets 21 as they approach each other by controlling the magnitude of the magnetic force, so that the thin wire 3 slowly moves away from the first tube 7 and slowly approaches the deposit. This achieves the purpose of making the volume of the deposit cleaned by the thin wire 3 small, which is convenient for subsequent absorption through the absorption hole 11. At the same time, it also achieves the purpose of fully cleaning the deposits in blood vessels of different sizes.

[0049] During the cleaning process, the water inlet device 41 and the absorption device 35 work synchronously. The water inlet device 41 squeezes the cleaning fluid into the closed section of the blood vessel through the outlet. The absorption device 35 sucks in the blood, cleaning fluid and deposits in the closed section through the absorption hole 11, thereby achieving the purpose of removing the cleaned deposits from the blood vessel. Simultaneously, the cleaning brush 9 moves with the first column 16 and continuously cleans the absorption hole 11, thus preventing the absorption hole 11 from becoming blocked.

[0050] After cleaning, the control device is turned off, the magnetism of the electromagnet ring 21 disappears, and the adjustment device 4 returns to its original state under the elastic recovery action of the spring 19. Then the first tube 7 is removed from the blood vessel. Through the above steps, the problem that most existing cerebrovascular endoscopy devices only have the function of vascular observation and cannot clean up some vascular blockages, such as cholesterol deposits, is solved.
