[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0029] Example 1

[0030] Reference Figure 1 and 2 , which is the first embodiment of the present invention, provides a medical magnetothermal ablation device, which includes a working mechanism 100 and an ablation mechanism 200.

[0031] Among them, the working mechanism 100 includes a workbench 101, a movable bed 102 arranged on one side of the workbench 101, and an inner cavity 103 opened in the workbench 101, and the movable bed 102 can move into the inner cavity 103. The ablation mechanism 200 is arranged in the workbench 101, and includes a high-frequency generator 201 arranged on the workbench 101, and a coil 202 arranged at the output end of the high-frequency generator 201 and located inside the workbench 101.

[0032] During use, the patient lies on the mobile bed 102 and is moved into the inner cavity 103 by the telescopic drive device on the mobile bed 102. At this time, the microsphere effect component Z with magnetic force is injected into the human body. The microsphere effect component Z can use microspheres of about 50um. The diameter of human capillaries is 4-10um, which can effectively prevent the microsphere effect component Z from entering the venous circulation through the capillaries, and at the same time better embolize to the terminal branch of the tumor supplying artery, while trying to keep the human body and the microsphere effect component Z at the center of the coil 202.

[0033] By starting the high frequency generator 201, the high frequency generator 201 applies high frequency current to the coil 202, and then generates a high frequency electromagnetic field on the active part Z through the coil 202, so that the molecules of the active part Z vibrate to generate heat to thermally ablate the tumor tissue.

[0034] Example 2

[0035] Reference Figure 1 and 3 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that the active member Z is a probe.

[0036] Compared with Example 1, further, the probe action piece Z is inserted into the target tumor tissue through thoracotomy or video-assisted thoracoscopy and minimally invasive methods. This method is a prior art and will not be explained in detail. By turning on the frequency generator 201 to apply high-frequency current to the coil 202, a high-frequency electromagnetic field is generated on the action piece Z through the coil 202, so that the molecules of the probe action piece Z vibrate to generate heat. The probe action piece Z inserted into the tumor tissue will thermally ablate the tumor tissue.

[0037] The remaining structures are the same as those of Example 1.

[0038] Example 3

[0039] Reference Figure 1 and Figures 4 to 6 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that it also includes a cooling mechanism 300, which is arranged in the workbench 101, and includes a fixing component 301 fixed inside the workbench 101, a water-cooling component 302 fixed in the fixing component 301, a water-cooling box 303 arranged at one end of the water-cooling component 302, a pump 304 fixed in the water-cooling box 303 and connected to one end of the water-cooling component 302, and a storage box 305 arranged away from the water-cooling component 302 and connected to the other end of the water-cooling box 303.

[0040] Compared with Example 2, during the use of the coil 202 when it is started, the pump 304 is started so that the pump 304 will suck the cooling liquid from the storage box 305 into the water cooling box 303 through the water cooling component 302. Since the water cooling component 302 and the coil 202 are fixed by the fixing component 301, and the coil 202 and the water cooling component 302 are staggered, during this process, the cooling liquid can cool the coil 202 through the water cooling component 302 and the fixing component 301.

[0041] Furthermore, the fixing component 301 includes a fixing part 301a for fixing the water cooling component 302 and the coil 202, a connecting groove 301b for clamping the water cooling component 302 and the coil 202, a cooling component 301c arranged inside the fixing part 301a, and a cooling cavity F opened inside the fixing part 301a.

[0042] The water cooling assembly 302 and the coil 202 can be fixed by the connecting groove 301b, and can effectively fix the water cooling assembly 302 and the coil 202 in a staggered arrangement to prevent them from being too close in the internal space. Since the cooling cavity F is provided, the heat generated by the coil 202 will condense therein. Similarly, the water cooling assembly 302 can also quickly cool down the fixing part 301a, allowing the fixing part 301a to transmit the temperature to the coil 202 for cooling.

[0043] The fixing member 301a can be made of flame-retardant heat-conductive materials, such as electronic silicone.

[0044] The remaining structure is the same as that of Example 2.

[0045] Example 4

[0046] Reference Figure 1 and Figures 4 to 7 , which is the fourth embodiment of the present invention. This embodiment is different from the third embodiment in that: the specific form of the water cooling component 302, the water cooling component 302 includes a first cooling pipe 302a connected to one end of the pump 304 and extending out of the water cooling box 303 and then extending to one end of the fixing member 301a, and a second cooling pipe 302b connected to one end of the storage box 305 and extending to the other end of the fixing member 301a.

[0047] Compared with Example 3, during use, the first cooling tube 302a and the second cooling tube 302b are not connected to each other, but one end of both are connected to the interior of the fixing member 301a, and there is a certain space between the first cooling tube 302a and the second cooling tube 302b extending into the interior of the fixing member 301a, and the space is a closed cavity G, that is, the end of the first cooling tube 302a and the second cooling tube 302b that is not connected forms a closed cavity G in the fixing member 301a.

[0048] Furthermore, the cooling component 301c includes a connecting shaft 301c-1 arranged in the fixing member 301a, a first fan blade 301c-2 arranged at one end of the connecting shaft 301c-1 and extending out of the closed cavity G, and a second fan blade 301c-3 arranged at the other end of the connecting shaft 301c-1 and extending out of the cooling cavity F, and the first fan blade 301c-2 is provided with a swirl portion H.

[0049] When the pump 304 is started, the pump 304 will generate suction through the first cooling tube 302a, and use the suction force to suck the cooling liquid in the storage box 305 toward the first direction Y into the water cooling box 303 through the closed cavity G and the second cooling tube 302b. In this process, the cooling liquid will hit the vortex point H of the first fan blade 301c-2, so that the first fan blade 301c-2 drives the connecting shaft 301c-1 to rotate.

[0050] A sealing roller is provided on the connecting shaft 301c-1 between the first cooling tube 302a and the second cooling tube 302b to effectively prevent water from leaking into the cooling chamber F. When the first fan blade 301c-2 drives the connecting shaft 301c-1 to rotate, the connecting shaft 301c-1 also drives the second fan blade 301c-3 to rotate to generate wind force, and guides the wind into the cooling chamber F. The wind entering the cooling chamber F can accelerate the air circulation inside it, speed up the heat exchange, and accelerate the cooling of the coil 202.

[0051] The remaining structure is the same as that of Example 3.
