Description

Technical Field

[0001] This invention relates to catheter systems, and more specifically, to catheter systems in which magnetic robots can be separated and joined using catheter modules. Background Art

[0002] Typically, to treat vascular diseases caused by narrowing or blockage due to thrombosis or other factors, a device is used: a catheter inserted through the femoral artery that allows the doctor to manually dilate and maintain the dilated blood vessel. Coronary angioplasty is then performed in the order the devices are inserted. However, the catheter's structural characteristics make it difficult to apply to complex blood vessels, and the success of the procedure largely depends on the surgeon's skill.

[0003] While existing catheter systems offer mechanisms for attaching and detaching magnetic robots from catheters using magnetic force, issues can arise due to repulsive forces acting between the magnets fixed to the catheter and the magnetic robot, leading to poor attachment. Furthermore, these repulsive forces can cause the magnetic robot to be pushed away or attached at an incorrect angle, potentially damaging blood vessels.

[0004] Therefore, there is a need for a conduit system that can stably connect with a magnetic robot without considering its position, posture, or rotation angle. Summary of the Invention

[0035] Reference Figures 1 to 5 The catheter system 10 includes a catheter module 100, a magnetic robot 200, and a magnetic field generating unit (not shown).

[0036] The catheter module 100 can be combined with and separated from the magnetic robot 200. When combined with the magnetic robot 200, the magnetic robot 200 can be deployed near the lesion. The catheter module 100 includes a catheter 110 and a rotating magnet 120.

[0037] The aforementioned catheter 110 is a tube-shaped tube of a specified length, which can be inserted into the coronal tissue of the body. The aforementioned catheter 110 can be made of a deformable, flexible material.

[0038] A receiving space 130 is formed inside the front end of the aforementioned conduit 110. The receiving space 130 may have a shape corresponding to the aforementioned rotating magnet 120.

[0039] A connecting groove 140 is formed on the outer peripheral surface of the conduit 110. The connecting groove 140 is formed at the front end of the conduit 110. The connecting groove 140 includes a first region 141 and a second region 142. The first region 141 extends from the front end of the conduit 110 along the rear end of the conduit 110 for a predetermined length. The second region 142 is formed along a direction perpendicular to the length direction of the first region 141 and communicates with the first region 141. According to an embodiment, the second region 142 may be formed along the circumferential direction of the conduit 110.

[0040] The rotating magnet 120 is inserted into the receiving space 130 and can rotate within the receiving space 130 under the control of an external magnetic field 20. The rotating magnet 120 can rotate around its central axis. The rotating magnet 120 can be divided into N poles and S poles based on the central axis. According to one embodiment, the rotating magnet 120 can be spherical.

[0041] When combined with the catheter module 110, the magnetic robot 200 can be deployed near the lesion. When separated from the catheter module 100, it can be moved and the lesion removed under the control of the magnetic field generating unit.

[0042] The aforementioned magnetic robot 200 includes a body 210 and a magnet part 230.

[0043] The aforementioned body 210 is a rod-shaped part of a specified length and is made of a non-magnetic material. A drill bit 270 is formed at the front end of the body 210, and a spiral protrusion can be formed on its outer peripheral surface. An inner space is formed inside the body 210. Furthermore, a connecting protrusion 220 and a fastening groove 260 are formed at the rear end of the body 210.

[0044] The aforementioned connecting protrusion 220 protrudes a predetermined length from the rear end of the aforementioned body 210. A locking portion 221 is formed at the end of the aforementioned connecting protrusion 220. Multiple such connecting protrusions 220 may be formed.

[0045] The aforementioned fastening groove 260 is formed at the rear end of the aforementioned body 210, and when the aforementioned conduit module 100 is combined with the aforementioned magnetic robot 200, it forms the space where the front end of the aforementioned conduit 110 is located. The aforementioned fastening groove 260 has a shape corresponding to the front end of the aforementioned conduit 110.

[0046] The magnet component 230 is combined with the body 210 and forms a magnetic force with the rotating magnet 120. The magnet component 230 includes a driving magnet 240 and a connecting magnet 250.

[0047] The aforementioned driving magnet 240 is inserted into the inner space of the aforementioned body 210 and is fixedly attached to the aforementioned body 210. The aforementioned driving magnet 240 and the aforementioned body 210 are driven as a single unit. The aforementioned driving magnet 240 is cylindrical and is divided into N poles and S poles along the axial direction of the aforementioned body 210.

[0048] The aforementioned connecting magnet 250 is formed behind the aforementioned driving magnet 240 and inserted into the aforementioned inner space. The aforementioned connecting magnet 250 is fixedly attached to the rear end of the aforementioned driving magnet 240. The aforementioned connecting magnet 250 is plate-shaped and has a diameter corresponding to the aforementioned driving magnet 240. The aforementioned connecting magnet 250 includes the aforementioned first magnet layer 251 and the aforementioned second magnet layer 252.

[0049] The first magnet layer 251 is plate-shaped and divided into N and S poles with respect to the axis of the main body 210. The second magnet layer 252 is also plate-shaped and divided into N and S poles with respect to the axis of the main body 210. The second magnet layer 252 is arranged opposite to the first magnet layer 251. The first magnet layer 251 and the second magnet layer 252 have the same polarity area. As a result, the magnetic moment value of the combined magnet 250 becomes 0 and is unaffected by the external magnetic field 20.

[0050] The aforementioned magnetic field generating unit generates an external magnetic field 20. The direction of the external magnetic field 20 may be perpendicular to the length direction of the conduit 110. Furthermore, the external magnetic field 20 may be a rotating magnetic field that rotates around the length axis of the conduit 110.

[0051] Figure 6 and Figure 7 The diagram illustrates the process of combining a catheter module with a magnetic robot according to an embodiment of the present invention. Figure 8 The diagram illustrates the separation process between the catheter module and the magnetic robot according to an embodiment of the present invention.

[0052] Reference Figure 6 and Figure 7 The aforementioned magnetic field generating unit generates the first external magnetic field 20 along a direction perpendicular to the length of the conduit module 100. The magnetic field generating unit controls the magnetic strength of the first external magnetic field 20 such that the magnetic force between the first external magnetic field 20 and the rotating magnet 120 is less than the magnetic force between the rotating magnet 120 and the magnet component 230. Thus, by aligning the magnetic fields of the rotating magnet 120 and the connecting magnet 250, they are configured to face each other with opposite polarities to the second magnet layer 252. Furthermore, as attraction acts between the rotating magnet 120 and the connecting magnet 250, the magnetic robot 200 moves towards the conduit module 100. In this case, the connecting protrusion 220 is inserted into the first region 141 of the fastening groove 260.

[0053] Furthermore, the aforementioned magnetic field generating unit generates a first rotating magnetic field 22 with the length direction of the aforementioned conduit module 100 as the axis. The aforementioned driving magnet 240 and the aforementioned body 210 rotate along the direction of the aforementioned first rotating magnetic field 22, and the aforementioned connecting protrusion 220 is located in the second region of the aforementioned fastening groove 260.

[0054] Through the above process, as the connecting protrusion 220 is fastened to the fastening groove 260, the magnetic robot 200 can be combined with the conduit module 100 by the magnetic force between the rotating magnet 120 and the connecting magnet 250.

[0055] Reference Figure 8 The aforementioned magnetic field generating section generates a second rotating magnetic field 23 in the opposite direction to the first rotating magnetic field 22. The aforementioned driving magnet 240 and the aforementioned body 210 rotate in opposite directions via the aforementioned second rotating magnetic field 23, and the aforementioned connecting protrusion 220 is located in the first region 141 of the aforementioned fastening groove 260.

[0056] Furthermore, the aforementioned magnetic field generating unit generates the second external magnetic field 21 along a direction perpendicular to the length of the conduit module 100. The magnetic field generating unit controls the magnetic strength of the second external magnetic field 21, such that the magnetic force between the second external magnetic field 21 and the rotating magnet 120 is greater than the magnetic force between the rotating magnet 120 and the magnet component 230. The rotating magnet 120 and the driving magnet 240 are aligned with the magnetic field direction of the second external magnetic field 21 by the second external magnetic field 21. This alignment causes the rotating magnet 120 and the second magnet layer 252 to be arranged with the same polarity facing each other, and as a repulsive force is generated between the rotating magnet 120 and the connecting magnet 250, the magnetic robot 200 is pushed forward toward the conduit module 100. During this process, the connecting protrusion 220 disengages from the first region 141 of the fastening groove 260.

[0057] Through the above process, the magnetic robot 200 can be separated from the conduit module 100.

[0058] Figure 9 A diagram illustrating a catheter system according to another embodiment of the present invention.

[0059] Reference Figure 9 The aforementioned magnet component 230 includes the aforementioned driving magnet 240. The shape and diameter of the aforementioned driving magnet 240 are similar to... Figure 8 The driving magnet 240 shown above is the same.

[0060] When the magnetic force between the first external magnetic field 20 and the rotating magnet 120 is less than the magnetic force between the rotating magnet 120 and the driving magnet 240, the rotating magnet 120 aligns with the driving magnet 240 through the magnetic field. Thus, as attraction acts between the rotating magnet 120 and the driving magnet 240, the magnetic robot 200 can be combined with the conduit module 100.

[0061] When the magnetic force between the first external magnetic field 20 and the rotating magnet 120 is greater than the magnetic force between the rotating magnet 120 and the driving magnet 240, both the rotating magnet 120 and the driving magnet 240 are aligned along the direction of the first external magnetic field 20 and arranged with the same polarity facing each other. Therefore, as a repulsive force acts between the rotating magnet 120 and the driving magnet 240, the magnetic robot 200 can be separated from the conduit module 100.

[0062] Figure 10 A diagram illustrating a catheter system according to another embodiment of the present invention.

[0063] Reference Figure 10 The rotating magnet 120 can be cylindrical. The rotating magnet 120 has N poles and S poles based on its central axis, and can rotate around the central axis. The rotating magnet 120 can rotate around the central axis via the magnetic field between itself and the second external magnetic field 21 or the magnet component 230.

[0064] While the present invention has been described in detail above through preferred embodiments, the scope of the invention is not limited to the specific embodiments and should be interpreted based on the appended claims. Furthermore, it should be understood that various modifications and variations can be made by those skilled in the art without departing from the scope of the invention.
