[0002] In the field of pet clinical oncology treatment, traditional methods such as surgical resection, radiotherapy, and chemotherapy all have obvious limitations. Magnetic Hyperthermia Therapy (MHT) has gradually attracted attention due to its minimally invasive and targeted advantages, and has advantages such as depth unrestriction, precise targeting, and repeatable treatment. However, it has the following inherent defects: the lack of an operating table or an unreasonable design of the operating table results in the inapplicability of the treatment device to pet clinical applications; the mechanical structure is complex, the energy consumption is too high, and the equipment occupies a large area; the lack of modular mechanical design requires combination with the improvement of distributed magnetic field generation technology.

[0003] In summary, the pet magnetic hyperthermia treatment device needs to be further improved, and a technical solution for magnetic induction tumor treatment with a more reasonable layout, better application effect, and more convenient control is an urgent technical problem to be solved by those skilled in the art. Summary of the Invention

[0004] To solve the above problems, the primary object of the present invention is to provide a D-ring pet magnetic hyperthermia treatment device, which is used to solve the technical problems of the current device having a complex mechanical structure, being inapplicable to pet clinical applications, and lacking a reasonable combination of mechanical design and magnetic field distribution technology.

[0005] To achieve the above object, the technical solution of the present invention is as follows:

[0006] The present invention provides a D-ring pet magnetic hyperthermia treatment device, including: a main body, including a bearing platform and a coil assembly, the coil assembly is arranged on the bearing platform, the coil assembly encloses to form a cavity, and the coil assembly is used to generate an alternating magnetic field when a treatment object with a magnetic medium implanted at the lesion site passes through the cavity; a sliding plate, arranged on the bearing platform and moving along a first direction through the cavity, and the side of the sliding plate facing away from the bearing platform is used to carry a treatment object with a magnetic medium implanted at the lesion site. By arranging a coil assembly on the bearing platform, the coil assembly encloses to form a cavity, enabling the sliding plate to move along the first direction through the cavity, and the sliding plate is used to carry a treatment object with a magnetic medium implanted at the lesion site, so that when the treatment object passes through the cavity of the coil assembly, an alternating current is passed through the coil assembly to generate an alternating magnetic field at the lesion site of the treatment object for the purpose of magnetic hyperthermia.

[0007] Further, the carrier table includes a carrier plate, the sliding plate is slidably disposed on the carrier plate, and the carrier plate and the coil assembly enclose a D-shaped ring. Specifically, the carrier plate and the sliding plate are spaced apart relatively. The carrier plate is used to carry and install the sliding plate. The position design of enclosing the D-shaped ring by the carrier plate and the coil assembly enables the coil assembly to form a D-shaped working area on the carrier table. Thus, when the sliding plate moves into the cavity of the coil assembly, the shape design and volume design of the D-shaped ring need to be able to accommodate the treatment object carried on the sliding plate.

Detailed implementation manners

[0024] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0025] To achieve the above objectives, the technical solution of the present invention is as follows:

[0026] Referring to Figures 1-6 as shown, this embodiment provides a D-ring pet magnetothermal therapy treatment device, including: the main body 10, including the carrier table 11 and the coil assembly 12, the coil assembly 12 is arranged on the carrier table 11, the coil assembly 12 encloses to form a cavity 120, and the coil assembly 12 is used to generate an alternating magnetic field when a treatment object with a magnetic medium implanted in the lesion site passes through the cavity 120; the sliding plate 20 is arranged on the carrier table 11 and moves along the first direction X through the cavity 120, and the side of the sliding plate 20 facing away from the carrier table 11 is used to carry the treatment object with a magnetic medium implanted in the lesion site. By arranging the coil assembly 12 on the carrier table 11, the coil assembly 12 encloses to form the cavity 120, enabling the sliding plate 20 to move along the first direction X through the cavity 120, and carrying the treatment object with a magnetic medium implanted in the lesion site by the sliding plate 20, so that when the treatment object passes through the cavity 120 of the coil assembly 12 and a current is passed through the coil assembly 12, the coil assembly 12 performs electromagnetic induction heating on the treatment object, achieving the purpose of generating an alternating magnetic field in the lesion site of the treatment object for magnetothermal therapy.

[0027] Further, the carrier 11 includes a carrier plate 111, on which the sliding plate 20 is slidably arranged. The carrier plate 111 and the coil assembly 12 enclose a D-shaped ring. The carrier plate 111 is arranged on the side of the carrier 11 close to the coil assembly 12. Both the carrier plate 111 and the sliding plate 20 extend along the first direction X. The carrier plate 111 is used to carry and slidably mount the sliding plate 20. The position design of enclosing a D-shaped ring by the carrier plate 111 and the coil assembly 12 enables the coil assembly 12 to form a D-shaped working area on the carrier 11. Thus, when the sliding plate 20 moves into the cavity 120 of the coil assembly 12, the shape design and volume design of the D-shaped ring can meet the purpose of accommodating the treatment object carried on the sliding plate 20.

[0028] Further, two ends of the coil assembly 12 are respectively connected to opposite sides of the carrier plate 111. Among them, the coil assembly 12 is fixedly connected to the carrier plate 111. The coil assembly 12 and the carrier plate 111 enclose a cavity 120. The cross-section of the cavity 120 in the first direction X is D-shaped, and the coil assembly 12 is C-shaped or U-shaped. Alternatively, the carrier plate 111 passes through the cavity 120 of the coil assembly 12. Among them, the coil assembly 12 is fixedly connected to the carrier 11 and is spaced from the carrier plate 111. The coil assembly 12 and the sliding plate 20 enclose a cavity 120. The cross-section of the cavity 120 in the first direction X is D-shaped, and the coil assembly 12 is D-shaped or O-shaped. By setting the relative position and connection relationship between the coil assembly 12 and the carrier plate 111, the structural design diversity of the coil assembly 12 is increased, and more embodiments can be applied to different needs of treatment objects in the market, such as being more applicable to treatment objects of different varieties or different body types.

[0029] Further, the coil assembly 12 and the carrier plate 111 enclose a first included angle w, and the first included angle w is less than or equal to 90°. Among them, when the first included angle w enclosed by the coil assembly 12 and the carrier plate 111 is equal to 90°, the utilization rate of the coil assembly 12 is high. When the first included angle w enclosed by the coil assembly 12 and the carrier plate 111 is less than 90°, the diversity requirements of the appearance of the device, the accommodation space, the variety of treatment objects, etc. of the present invention can be met.

[0030] Further, the coil assembly 12 includes a plurality of single coils 121, and the single coils 121 are arranged at intervals around the first direction. The single coil 121 is one of D-shaped, C-shaped, U-shaped, and O-shaped. Preferably, any two adjacent single coils 121 are arranged in parallel and at equal distances. Through the design of different arrangement methods of the single coils 121, the coil assembly 12 can generate different alternating magnetic field ranges when passing through current, so that the generated alternating magnetic field accuracy is more accurate.

[0031] Further, the D-ring pet magnetothermal therapy device of the present invention further includes a control component 30. The control component 30 is electrically connected to the sliding plate 20 and is used to drive the moving direction, displacement or speed of the sliding plate 20 relative to the bearing platform 11. When the D-ring pet magnetothermal therapy device needs to work, the control component 30 first controls the sliding plate 20 to move towards the end away from the coil assembly 12. The treatment object with the magnetic medium implanted at the lesion site is placed on the sliding plate 20. Then the control component 30 controls the sliding plate 20 to move towards the end close to the coil assembly 12, and the treatment object with the magnetic medium implanted at the lesion site moves to the position of the cavity 120, so that when the coil assembly 12 provides an alternating current, an alternating magnetic field is generated in the cavity 120 of the coil assembly 12 for magnetothermal therapy of the treatment object.

[0032] Further, the D-ring pet magnetothermal therapy device of the present invention further includes a power supply component 40. The power supply component 40 is arranged on the bearing platform 11 and is electrically connected to the coil assembly 12. The power supply component 40 is used to provide an alternating current to the coil assembly 12.

[0033] Further, the D-ring pet magnetothermal therapy device of the present invention further includes a transformer 50. The transformer 50 is arranged on the bearing platform 11 and is connected to the power supply component 40 for providing an alternating voltage to the power supply component 40.

[0034] Further, the control component 30 is electrically connected to the power supply component 40 and the transformer 50, and the control component 30 is used to control the intensity or frequency of the alternating current generated by the coil assembly 12. By connecting the control component 30 to the power supply component 40 or the transformer 50, the intensity or frequency of the alternating current generated by the coil assembly 12 is controlled, and then when the coil assembly 12 performs electromagnetic induction heating on the treatment object, the alternating frequency or the magnitude of the central magnetic field intensity of the generated magnetic field is controlled.

[0035] Further, the main body 10 further includes a cooling pipeline (not shown). The cooling pipeline is arranged inside the coil assembly 12 and is arranged in an alternating and spaced manner with the single coil 121. Further, the coil assembly 12 includes a housing 122. The housing 122 is a hollow structural member. The cooling pipeline is located inside the housing 122, and the housing 122 is used to accommodate and wrap the single coil 121 and the cooling pipeline. By arranging the cooling pipeline in an alternating and spaced manner with the coil assembly 12, the purpose of fully cooling the coil assembly 12 by the cooling pipeline to reduce the heat loss of the coil assembly 12 is achieved. Further, the control component 30 is connected to the cooling pipeline and is used to control the cooling pipeline to provide a cold source to the coil assembly 12 or stop providing a cold source to the coil assembly 12.

[0036] Furthermore, a first receiving groove 112 and a second receiving groove 113 are provided on a side of the supporting plate 111 proximate to the sliding plate 20. Both the first receiving groove 112 and the second receiving groove 113 are recessed from the surface of the supporting plate 111 along the third direction Z toward the side facing away from the sliding plate 20. The supporting plate 111, the first receiving groove 112, and the second receiving groove 113 enclose a receiving cavity. Preferably, the first receiving groove 112 and the second receiving groove 113 extend along the first direction X and are spaced apart from each other. The first receiving groove 112 and the second receiving groove 113 are aligned along the second direction Y. The first receiving groove 112 and the second receiving groove 113 have equal depths along the third direction Z. More preferably, a hollowing design is added between the first receiving groove 112 and the second receiving groove 113 to save material and reduce weight.

[0037] Furthermore, the sliding plate 20 includes a first plate body 21 and a second plate body 22 that are arranged in contact with each other. The second plate body 22 is arranged on the side of the first plate body 21 close to the supporting plate 111. The two end portions of the first plate body 21 are respectively protruded along the first direction X and arranged at the two end portions of the second plate body 22. The two side ends of the first plate body 21 are respectively aligned along the second direction Y and arranged at the two side ends of the second plate body 22. The first plate body 21 is fixedly connected to the second plate body 22, and the second plate body 22 is slidably fitted in the accommodating cavity.

[0038] Furthermore, a first limiting portion is provided in the first accommodating groove 112, and a second limiting portion is provided in the second accommodating groove 113; the second plate body 22 is slidably configured in the first accommodating groove 112 through the first limiting portion, and the second plate body 22 is slidably configured in the second accommodating groove 113 through the second limiting portion.

[0039] Furthermore, either the first limiting portion or the second limiting portion includes a slide rail 117 extending along the first direction X and a slider 118 slidably arranged on the slide rail 117 , and the side of the second plate 22 facing away from the first plate 21 is fixedly connected to the slider 118 .

[0040] It should be noted that to prevent the second plate 22 of the sliding plate 20 from moving excessively from the supporting plate 111 and causing a risk of falling, a retaining wall 114 is provided at one end of the supporting plate 111 away from the coil assembly 12 along the first direction X. The top surface 115 of the retaining wall 114 along the third direction Z is higher than the bottom wall 116 of the first accommodating groove 112 and the bottom wall 116 of the second accommodating groove 113. As a result, the second plate 22 always moves within the accommodating cavity along the first direction X. The design of the retaining wall 114 and the accommodating cavity provides a protective limit for the sliding plate 20, reducing the risk of the treatment subject falling while positioned on the sliding plate 20.

[0041] Alternatively, neither the first limiting portion nor the second limiting portion is specifically set as the slide rail 117 and the slider 118. A first limiting portion extending along the first direction X is provided on one side of the bearing plate 111 close to the sliding plate 20; a second limiting portion is provided on one side of the sliding plate 20 close to the bearing plate 111, and the second limiting portion is slidably engaged with the first limiting portion. By providing the first limiting portion on the bearing plate 111 and the second limiting portion on the sliding plate 20, the first limiting portion and the second limiting portion are slidably engaged to achieve the purpose of slidably mounting the sliding plate 20 on the bearing plate 111.

[0042] Further, a splicing design is carried out between the first accommodating groove 112 and the second accommodating groove 113 to replace the hollow design between the first accommodating groove 112 and the second accommodating groove 113 in the above embodiment. There is one first limiting portion; alternatively, there are multiple first limiting portions, and the multiple first limiting portions are arranged at parallel intervals in the second direction Y, and the second direction Y is perpendicular to the first direction X; there is one group or multiple groups of second limiting portions, and the second limiting portions are correspondingly arranged with the first limiting portions, and the second limiting portions are connected to the sliding plate 20. When there is one first limiting portion and one group of second limiting portions, the first limiting portion is arranged along the first direction X on the center line of the bearing plate 111, and the second limiting portion is arranged along the first direction X on the center line of the sliding plate 20, so that the sliding plate 20 slides stably on the bearing plate 111; when there are multiple first limiting portions and multiple groups of second limiting portions, the first limiting portions are symmetrically arranged along the first direction X on the bearing plate 111. Through multiple groups of sliding fits between the first limiting portions and the second limiting portions, the limiting fit between the sliding plate 20 and the bearing plate 111 is increased to provide support, so that the sliding plate 20 is more stable when moving.

[0043] In addition, the host 10 further includes a housing 13, and the housing 13 is used to wrap the bearing table 11, the power supply assembly 40, the transformer 50, and the control assembly 30, so that the appearance of the host 10 is neat and the external volume and floor area of the host 10 are reduced.

[0044] The operation process of using the D-ring pet magnetothermal therapy device of the present invention for a treatment object with a magnetic medium implanted in the lesion site includes:

[0045] Take appropriate sanitary disinfection measures before treatment, such as trimming the treatment area and disinfecting the injection area with iodophor;

[0046] After determining the appropriate dose, draw the necessary volume into a sterile syringe using a 23-27 gauge needle;

[0047] During injection, insert the needle into a single injection site of the tumor mass; while applying uniform pressure to the syringe plunger, move the needle back and forth to inject the veterinary drug into different positions within the tumor; ensure that the injection is limited only within the tumor mass and not injected into the tumor edge or beyond the tumor periphery;

[0048] After injecting the full dose of veterinary medicine, pause for 5 seconds to allow it to disperse into the tissue before withdrawing the needle from the tumor;

[0049] After injection, use CT to locate the position of the magnetic fluid, and then place the pet in the magnetic field generating device;

[0050] Adjust the intensity and frequency of the magnetic field generator. When the temperature in the central area of hyperthermia reaches 46°C and stabilizes, treat for another 15 minutes.

[0051] It should be noted that the magnetic medium implanted in the lesion site of the treatment object is equivalent to the magnetic fluid. The main component of the magnetic fluid is iron oxide nanoparticles coated with PEG2000, with a concentration of 200 mg / mL, or a concentration of 112 mg / mL in terms of Fe measurement. The treatment objects of the present invention are mainly used for feline and canine solid tumors, applicable to tumors with a volume in the range of 1 cm 3 ~8 cm 3 and are easy to inject intratumorally. Administered through the intratumoral injection route, the magnetic fluid is stored in a vial for intratumoral injection. Among them, the injection dose is 0.2 μL of magnetic fluid per cm 3 of tumor volume. The calculation formula for tumor size needs to satisfy: tumor volume (cm 3 ) = π / 6 (length * width * height)), and this tumor volume calculation formula is closer to the real volume. The dose calculation formula satisfies: injection volume (mL) = tumor volume (cm 3 ) * 0.2.

[0052] The D-ring pet magnetic hyperthermia treatment device provided by the present invention includes: a main body 10, including a carrier table 11 and a coil assembly 12. The coil assembly 12 is arranged on the carrier table 11, and the coil assembly 12 encloses a cavity 120. The coil assembly 12 is used to pass an electric current to generate an alternating magnetic field when a treatment object with a magnetic medium implanted in the lesion site passes through the cavity 120; a sliding plate 20, arranged on the carrier table 11 and moving along the first direction X through the cavity 120. The side of the sliding plate 20 facing away from the carrier table 11 is used to carry the treatment object with a magnetic medium implanted in the lesion site. Compared with the prior art, in this application, by setting the carrier table 11, the coil assembly 12 and the sliding plate 20, when an electric current is passed through the coil assembly 12, an alternating magnetic field is generated in the cavity 120 at the lesion site of the treatment object, thereby performing magnetic hyperthermia on the treatment object; at the same time, the structure of this application is simple and convenient to install, making the operation more convenient.
