Technical Field

[0001] The utility model relates to the technical field of medical equipment, and more specifically, to a multi-amplitude microwave radiator device. Background Art

[0002] In existing technology, radiators illuminate the affected area of ​​the human body, leveraging the unique physical properties of microwaves, including thermal and non-thermal effects, to promote absorption by diseased tissue, accelerate blood and fluid circulation, enhance local tissue immunity, and restore the affected tissue to normal. Currently, radiators of different specifications are typically used to target different areas and lesion sizes. This means that traditional machines require multiple radiators, which must be replaced based on the specific treatment scenario. Furthermore, unused radiators take up valuable space and cost.

[0003] In summary, how to provide a radiator that is applicable to different parts of the body and the size of the lesion area is an urgent problem to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of the present invention is to provide a multi-amplitude microwave radiator device, which is applicable to different parts and sizes of lesion areas.

[0005] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0007] upper shell;

[0008] Fixed plate;

[0009] a microwave adapter, one end of which penetrates into the upper shell, and the microwave adapter is fixed to the upper shell through the fixing plate;

[0010] an antenna coil, located inside the upper housing and connected to an end of the microwave adapter, the antenna coil being used to emit microwaves outward;

[0011] The lower shell assembly includes a lower shell that is covered and connected with the upper shell to form a cavity, an adjustment plate and a driving member. The two adjustment plates are relatively distributed. The driving member is connected to the adjustment plates and both are arranged in the cavity. The adjustment plates and the inner wall of the upper shell are used to reflect the microwaves. The driving member is used to drive the adjustment plates to rotate to change the emission direction of the microwaves.

[0012] In one embodiment, the upper housing comprises an aluminum alloy plate or a plastic plate.

[0013] In one embodiment, the fixing plate comprises a stainless steel metal plate.

[0014] In one embodiment, the antenna coil comprises a helical copper tube.

[0015] In one embodiment, the driving member includes a fixed shaft, a pressure plate, a knob, and a spring rod, the adjusting plate is sandwiched between two fixed shafts on the same side, and the fixed shaft and the adjusting plate are fixed by a locking member;

[0016] The end of the fixed shaft is arranged on the side of the lower shell, the knob is fastened to the end of the fixed shaft, the two ends of the spring rod are respectively inserted into the two adjustment plates, and the middle part of the spring rod is pressed on the lower shell through the pressure plate.

[0017] In one embodiment, the lower housing comprises a piece of wave-transparent material.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] The core of the utility model is to provide a multi-amplitude microwave radiator device, which is applicable to different parts and sizes of lesion areas.

[0038] Please refer to Figures 1 to 8 .

[0039] This specific embodiment provides a multi-amplitude microwave radiator device, including:

[0040] Upper shell 2;

[0041] Fixed plate 3;

[0042] A microwave adapter 1, one end of which penetrates into the upper housing 2, and the microwave adapter 1 is fixed to the upper housing 2 via a fixing plate 3;

[0043] The antenna coil 4 is located inside the upper housing 2 and connected to the end of the microwave adapter 1. The antenna coil 4 is used to emit microwaves outward.

[0044] The lower shell assembly 5 includes a lower shell 501 that is covered and connected with the upper shell 2 to form a cavity, an adjustment plate 502, and a driving member. The two adjustment plates 502 are distributed relatively to each other. The driving member is connected to the adjustment plates 502 and both are arranged in the cavity. The adjustment plates 502 and the inner wall of the upper shell 2 are used to reflect microwaves. The driving member is used to drive the adjustment plates 502 to rotate to change the emission direction of the microwaves.

[0045] During actual use, the shape, structure, size, material, position, etc. of the upper shell 2, the fixing plate 3, the microwave adapter 1 and the lower shell assembly 5 can be determined according to actual conditions and actual needs.

[0046] When using the multi-amplitude microwave radiator device provided by the present invention, the antenna coil 4 emits microwaves. The operator can control the driving element to rotate the adjustment plate 502, changing the position of the adjustment plate 502, which reflects the microwaves. This allows the adjustment plate 502 and the inner wall of the upper housing 2 to form different irradiation areas. In other words, adjusting the position of the adjustment plate 502 allows the microwave radiation range and amplitude to be adjusted. For example, conventional radiation therapy for the arm requires a circular radiator, radiation therapy for the lungs requires a rectangular radiator, and radiation therapy for the waist requires a saddle-shaped radiator. However, the present device can simply rotate the adjustment plate 502 by controlling the driving element, thereby changing the treatment area, eliminating the need for frequent replacement of different radiators. Therefore, the present device achieves a simple structure, low cost, and easy adjustment. It allows for multi-amplitude and multi-range adjustment of a single radiator, saving the time required to frequently replace different radiators and reducing the use of valuable space resources. It is also convenient for medical personnel to use, reducing the workload of medical personnel.

[0047] In summary, the multi-amplitude microwave radiator device provided by the present invention is applicable to different parts of the body and sizes of lesion areas.

[0048] In one embodiment, the upper housing 2 comprises an aluminum alloy plate or a plastic plate. Specifically, the upper housing 2 may be stamped from an aluminum alloy plate, or may be injection molded or vacuum molded. The inner surface of the upper housing 2 may be electrolessly plated, sputtered, or sprayed with a conductive paint to impart microwave shielding and reflection capabilities.

[0049] In one embodiment, the fixing plate 3 includes a stainless steel metal plate, so that the fixing plate 3 can effectively fix the microwave adapter 1 without affecting the connection between the microwave adapter 1 and the antenna coil 4 .

[0050] In one embodiment, the antenna coil 4 comprises a spiral copper tube. For example, the antenna coil 4 can be formed by spirally winding a copper tube. A copper tube is a type of non-ferrous metal tube. It is a pressed and drawn seamless tube with advantages such as light weight and good thermal conductivity.

[0051] It should be noted that the microwave adapter 1, the upper shell 2 and the fixing plate 3 can be fastened together by countersunk screws, and the antenna coil 4 is connected to the microwave adapter 1 as a whole by welding, so that power is supplied to the antenna coil 4 through the microwave adapter 1, so that the antenna coil 4 emits microwaves outward, and the welding method can ensure the connection effect and conduction effect between the microwave adapter 1 and the antenna coil 4.

[0052] In one embodiment, Figure 1 and Figure 5As shown, the driving member includes a fixed shaft 503, a pressure plate 504, a knob 505 and a spring rod 506. An adjustment plate 502 is sandwiched between the two fixed shafts 503 on the same side, and the fixed shaft 503 and the adjustment plate 502 are fixed by a locking member; the end of the fixed shaft 503 is provided on the side of the lower shell 501, and the knob 505 is fastened to the end of the fixed shaft 503. The two ends of the spring rod 506 are respectively inserted into the two adjustment plates 502, and the middle part of the spring rod 506 is pressed on the lower shell 501 through the pressure plate 504.

[0053] It should be noted that an adjustment plate 502 can be sandwiched between the two fixed shafts 503, that is, the two fixed shafts 503 and the adjustment plate 502 can be fastened together using screws. Furthermore, the ends of the fixed shafts 503 are round shafts, and the ends of the fixed shafts 503 are clamped on the front and rear sides of the lower housing 501. Afterwards, the knobs 505 can be fastened to the ends of the fixed shafts 503, with the two fixed shafts 503 on the left forming a group, and the two fixed shafts 503 on the right forming a group. Then, the ends of the spring rods 506 are respectively inserted into the holes on the left and right adjustment plates 502, and the pressure plates 504 are then fastened with screws to press the spring rods 506 against the lower housing 501. Finally, rotating the knobs 505 can achieve the purpose of causing the adjustment plates 502 to rotate with the knobs 505.

[0054] During use of the device, the operator can adjust the positions of the two adjustment plates 502 simply by rotating the knobs 505. For example, the left or right knob 505 can be rotated to cause the left or right adjustment plate 502 to rotate synchronously, or both knobs 505 can be rotated simultaneously to cause the left and right adjustment plates 502 to rotate synchronously. Ultimately, the range of the microwave reflection area formed by the adjustment plates 502 and the inner wall of the upper housing 2 can be changed, thereby adjusting the microwave radiation range and amplitude.

[0055] For example, when the affected area is a small area of ​​the arm, Figure 6 As shown, the adjustment plates 502 on both sides can be arranged vertically relative to the lower shell 501, so that the area of ​​the microwave radiation area is relatively small; when the patient's area is relatively large, such as the lungs, Figure 9 As shown, the adjustment plate 502 on one side can be vertically distributed relative to the lower shell 501, and the adjustment plate 502 on the other side can be tilted relative to the lower shell 501, so that the area of ​​the microwave radiation zone is relatively increased; when the patient's part is the waist with a relatively larger area, as shown in Figure 8, the adjustment plates 502 on both sides can be horizontally distributed relative to the lower shell 501 (that is, the two adjustment plates 502 are opened to the maximum range), so that the area of ​​the microwave radiation zone is relatively maximized.

[0056] In one embodiment, the lower housing 501 comprises a piece of wave-transparent material.

[0057] It should be noted that wave-transmitting materials include antenna windows and radomes. These materials are primarily used to protect aircraft systems such as communications, telemetry, guidance, and detonation systems from operating in harsh environments. Wave-transmitting materials are insulating materials that allow radio frequency electromagnetic waves to pass through with minimal loss and distortion. They are primarily used to manufacture various radomes and protect antennas of radar and other electronic equipment from harmful environmental influences. Lower housing 501 can be constructed using a plastic shell injection molding or vacuum molding process, and is made of a wave-transmitting material such as PP (polypropylene). PP, a polymer formed by the polyaddition reaction of propylene, is a colorless, odorless, non-toxic, translucent, lightweight, general-purpose thermoplastic. It exhibits excellent heat and chemical resistance, electrical insulation, high mechanical strength, and excellent wear resistance.

[0058] In one embodiment, the bottom surface of the lower shell 501 is provided with a plurality of protrusions 507 arranged in a matrix, so as to keep a certain distance between the lower shell 501 and the treatment site, thereby preventing overheating and burns caused by close contact with the patient.

[0059] In one embodiment, the adjustment plate 502 is a single-sided copper-clad electrical plate to isolate and reflect microwaves. Therefore, when the antenna coil 4 emits microwaves, the copper layer above the adjustment plate 502 is not penetrated by the microwaves and is reflected by the copper layer. By adjusting the position of the adjustment plate 502, the operator can achieve different irradiation areas.

[0060] In one embodiment, the fixed shaft 503 includes a plastic part, and the pressing plate 504 includes a plastic pressing sheet, so as to prevent the fixed shaft 503 and the pressing plate 504 from affecting the microwave isolation and reflection process of the adjustment plate 502 .

[0061] In one embodiment, the spring rod 506 comprises a metal spring rod wrapped with a non-metallic cladding, so that the spring rod 506 has a certain elastic force and the spring rod 506 does not affect the microwave isolation and reflection process of the adjustment plate 502. Moreover, in the initial state, the axial direction of the adjustment plate 502 and the axial direction of the spring rod 506 are perpendicularly distributed. Figure 6 As shown, the spring rod 506 can press the adjustment plate 502 (ie, the end of the spring rod 506 can apply downward pressure to the adjustment plate 502), so that the adjustment plate 502 can be turned to a desired position and remain stationary. Figure 7 As shown, when the adjustment plate 502 is flipped to a certain angle, the spring rod 506 passes through the hole of the adjustment plate 502, and one side of the lower edge of the adjustment plate 502 is subjected to a vertical downward force F1, and the other side of the upper edge of the adjustment plate 502 is subjected to a vertical upward force F2 to maintain balance, thereby keeping the adjustment plate 502 stationary.

[0062] It should also be noted that this device utilizes a fixed shaft 503 + spring rod 506 + pressure plate 504 combination to achieve rotational adjustment of the adjustment plate 502. The operator simply rotates the knob 505 to adjust the position of the adjustment plate 502, thereby adjusting the microwave radiation range and amplitude. Furthermore, a boss can be provided on the lower housing 501 for the spring rod 506 to pass through. The pressure plate 504 is then secured to the boss with screws to prevent the spring rod 506 from disengaging from the adjustment plate 502 during its rotation. This allows the two ends of the spring rod 506 to apply pressure to the two adjustment plates 502.

[0063] In addition, it should be noted that the directions or positional relationships indicated by "left and right", "up and down", etc. in the present invention are based on the directions or positional relationships shown in the accompanying drawings, and are only for the purpose of simplifying the description and facilitating understanding, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, it cannot be understood as a limitation on the present invention.

The same or similar parts between the various embodiments can be referenced to each other.
