[0002] The technique of using high-frequency electric fields generated by electrodes to directly act on the tumor area to perform dielectric heating or interfere with the mitosis of tumor cells, thereby causing local repair or necrosis, has received increasing attention.

[0003] Existing high-frequency electric field tumor treatment devices mostly involve direct or indirect contact between electrodes and the human body. A search revealed no similar technical solutions to this invention. Summary of the Invention

[0004] The present invention aims to solve the technical problems existing in the prior art. The purpose of the present invention is to provide a non-contact high-frequency electric field generation and field-construction structure and a treatment device using the structure.

[0005] To achieve the above objectives, according to a first aspect of the present invention, a non-contact high-frequency electric field generator and field-constructing structure is disclosed, comprising M inner field electrode units, wherein the treatment position is located within the area enclosed by the M inner field electrode units and is not in contact with any of the inner field electrode units, each inner field electrode unit comprising multiple (two or more) electrode structures at different distances from the treatment position, wherein M is a positive integer greater than 1, and the electrode structures are connected to or emit high-frequency waves and are capable of transmitting them to the treatment position.

[0006] The non-contact high-frequency electric field generation and field-construction structure of the present invention achieves non-contact treatment by setting up M inner field electrode units. The treatment position is located within the area enclosed by the M inner field electrode units and does not come into contact with any of the inner field electrode units. Each inner field electrode unit includes multiple electrode structures at different distances from the treatment position. The superposition of high-frequency waves emitted by different electrode structures improves the treatment effect.

[0007] According to a preferred embodiment of the present invention, the M inner field electrode units are arranged circumferentially around the treatment position. By centering the treatment position, the therapeutic effect is improved.

[0008] According to another preferred embodiment of the present invention, there are two inner field electrode units arranged opposite to each other. The two oppositely arranged inner field electrode units have a simple structure and are easy to implement.

[0009] According to another preferred embodiment of the present invention, multiple electrode structures of the same inner field electrode unit are arranged radially with the treatment position as the center. The preceding electrode structure (the electrode structure closest to the treatment position is the preceding electrode unit) partially or completely obscures the following electrode units, which facilitates the superposition of high-frequency waves emitted by different electrode structures and improves the treatment effect.

[0010] According to another preferred embodiment of the present invention, the spacing between multiple electrode structures in the same inner field electrode unit is adjustable. This allows for adjustment of the superposition effect of high-frequency waves emitted by different electrode structures.

[0012] According to yet another preferred embodiment of the present invention, the size of multiple electrode structures in the same inner field electrode unit increases sequentially with increasing distance from the treatment position. This sequential increase in size with increasing distance from the treatment position allows for the emission of more high-frequency waves at locations farther from the treatment position, ensuring better treatment efficacy.

[0013] According to another preferred embodiment of the present invention, a treatment mechanism for supporting the patient is provided at the treatment position. This facilitates the patient's lying down or sitting, improving the treatment effect.

[0015] According to another preferred embodiment of the present invention, all M internal field electrode units provide unipolar or bipolar high-frequency output. Various implementation methods are possible.

[0016] According to yet another preferred embodiment of the present invention, the inner field monopolar output electrode unit is at the same potential as the treatment mechanism. This prevents the formation of current loops and improves safety.

[0017] According to another preferred embodiment of the present invention, the electrode structure is an electrode plate, a high-frequency oscillation box, or a combination of both, and the electrode structure is connected to a high-frequency generator. The high-frequency emission methods are diverse.

This enables the transmission of high-frequency waves.

[0019] According to another preferred embodiment of the present invention, the high-frequency oscillator has a housing, the housing being lined with a high-frequency waveguide material and a high-frequency reflective coating material, and the housing having an opening on the side facing the treatment position or being made of a high-frequency permeable material. When a high-frequency oscillator is used, efficient high-frequency emission is ensured.

[0020] According to yet another preferred embodiment of the invention, an outer field electrode unit is also included, located around the inner field electrode unit. By providing an outer field, the therapeutic effect is improved.

[0021] According to another preferred embodiment of the present invention, the external field electrode unit is connected to a high-frequency generator to output radio waves. By setting an external field, the electromagnetic field environment and harmonic environment of nature are simulated, thereby improving the therapeutic effect.

[0022] According to yet another preferred embodiment of the present invention, the inner field electrode unit and the outer field electrode unit operate synchronously or in a time-sharing manner.

[0023] According to another preferred embodiment of the present invention, the inner field electrode unit operates continuously during the treatment period, while the outer field electrode unit operates intermittently during the treatment period. This provides versatility in operating modes.

[0024] To achieve the above objectives, according to a second aspect of the present invention, a treatment device is disclosed, comprising a leak-proof housing and an electric field generating and field-constructing structure disposed within the housing, wherein the electric field generating and field-constructing structure is the non-contact high-frequency electric field generating and field-constructing structure of the present invention. By providing the leak-proof housing and the electric field generating and field-constructing structure, effective high-frequency treatment is achieved.

For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0035] In a first preferred embodiment of the present invention, the present invention provides a non-contact high-frequency electric field generating and field-constructing mechanism, such as... Figure 1 As shown, it includes M inner field electrode units 1. The treatment position 2 is located within the area enclosed by the M inner field electrode units and does not contact any of the inner field electrode units. Each inner field electrode unit 1 includes multiple electrode structures 11 at different distances from the treatment position. M is a positive integer greater than 1. The electrode structures emit high-frequency waves that can be transmitted to the treatment position. In this embodiment, the number of inner field electrode units 1 can be set according to actual needs, and can be 2, 3, 4, 5 or more. Preferably, there are 2 units, with the 2 inner field electrode units 1 arranged opposite each other, preferably on the upper and lower sides of the treatment position 2 respectively.

[0036] In this embodiment, a treatment mechanism 3 for supporting the patient is provided at treatment position 2. Specifically, treatment mechanism 3 can be a treatment bed or a treatment chair. An electrode pad is provided on the upper surface of the treatment mechanism to allow more high-frequency waves to penetrate the patient's body, improving the treatment effect. Specifically, the electrode pad can be any conductive pad material that can guide waves under wire insulation, preferably conductive cloth or conductive rubber.

[0037] Taking treatment facility 3 as an example, such as Figure 1 As shown (facing) Figure 1 The direction is either the top of the patient's head or the side of the patient's body. M internal field electrode units 1 are arranged circumferentially around the treatment position 2. Specifically, the distances of the M internal field electrode units 1 from the center of the treatment position 2 can be the same or different.

[0038] In this embodiment, multiple electrode structures 11 of the same inner field electrode unit are arranged radially around the treatment position (preferably the center of the treatment mechanism 3). The spacing between the multiple electrode structures of the same inner field electrode unit is adjustable. Specifically, the multiple electrode structures of the treatment mechanism 3 are connected by a telescopic link or a continuous robot to adjust the relative distance between the multiple electrode structures of the same inner field electrode unit. The specific adjustment method can adopt existing technology. Specifically, the telescopic link or continuous robot is preferably made of a non-polarizing material, such as polystyrene.

[0039] The multiple electrode structures 11 of the same inner field electrode unit 1 may be the same size, different size, or not completely the same size. Preferably, the size of the multiple electrode structures 11 of the same inner field electrode unit 1 increases sequentially with the distance from the treatment position. In a more preferred embodiment, the multiple electrode structures 11 may partially overlap or not overlap each other, that is, the electrode structures 11 are partially or completely exposed relative to the treatment mechanism 3, and the high-frequency waves emitted by the electrode structures 11 are partially reflected or completely transmitted to the treatment mechanism 3 by the preceding electrode structures 11.

[0040] Specifically, each of the M internal field electrode units 1 provides either unipolar or bipolar high-frequency output. When in unipolar output mode, the internal field unipolar output electrode unit is at the same potential as the treatment mechanism.

[0041] Electrode structure 11 is an electrode plate, a high-frequency oscillation box, or a combination of both. When the electrode structure is an electrode plate, the high-frequency generator structure is as follows: the electrode plate is connected to a high-frequency AC voltage source, or the electrode plate is connected to both a high-frequency AC voltage source and a DC voltage source. When the electrode structure is a high-frequency oscillation box, the high-frequency oscillation box is connected to a high-frequency oscillator; or the high-frequency oscillation box is connected to both a high-frequency oscillator and a signal generator. The high-frequency oscillator has a housing, and the housing is coated with a high-frequency reflective material, such as a metal material. The housing has an opening on the side facing the treatment position or is made of a high-frequency permeable material, such as a plastic material, preferably a non-polarized plastic material.

[0042] The specific electrode structure emits high-frequency waves with a frequency ≥50kHz. For example, a high-frequency AC voltage source connected to the electrode plate emits an AC signal with a frequency ≥50kHz and a voltage less than 5000V; or a high-frequency AC voltage source connected to the electrode plate emits an alternating voltage with a frequency of 50kHz-500kHz and an amplitude less than 250V; the high-frequency waves emitted by the electrode structure can be superimposed with DC voltages of 900-20000V. During specific treatments, the high-frequency waves emitted by the electrode structure can be varied within the above parameter range according to the actual situation.

[0043] In a second preferred embodiment of the invention, such as Figure 2 As shown, in addition to having all the structures of the first preferred embodiment, it also includes an outer field electrode unit 4 located around the inner field electrode unit. The outer field electrode unit 4 is arranged correspondingly to the inner field electrode unit 1, and the number of outer field electrode units 4 and inner field electrode units 1 may be the same or different.

[0044] In this embodiment, the external field electrode unit is connected to a high-frequency generator to output radio waves. The external field electrode unit can output radio waves bipolarly. The frequency of the radio waves is 10kHz-2.4GHz, and the composite field strength is <10V / m.

[0045] In this embodiment, the inner field electrode unit and the outer field electrode unit operate synchronously or in shifts. Preferably, the inner field electrode unit operates continuously during the treatment period, while the outer field electrode unit operates intermittently during the treatment period. Preferably, a treatment period is from 30 minutes to 3 hours, with the outer field electrode unit operating for a short period at the beginning (e.g., the first 5 minutes of the treatment period) or at regular intervals (e.g., 5 minutes every half hour).

[0046] In the first and second embodiments of the present invention, the inner field electrode unit and the outer field electrode unit have a straight structure or an arc-shaped structure.

[0047] In the third preferred embodiment of the present invention, such as Figure 3As shown, the treatment device includes a leak-proof housing 5 and an electric field generating and field-constructing structure disposed within the housing. The electric field generating and field-constructing structure is the non-contact high-frequency electric field generating and field-constructing structure of the present invention. Specifically, it can be the structure in the first embodiment or the structure in the second embodiment.

[0048] like Figure 4 As shown, the high-frequency generator 5, the amplitude modulation signal generator 6, and the high-frequency generator 7 are located outside the leak-proof housing. A sound playback device 8 and a gas supply device 9 are also located outside the leak-proof housing. The sound playback device 8 and the gas supply device 9 have outlets on or inside the leak-proof housing.

[0049] In specific treatment procedures, a temperature detection unit can be installed inside or on the patient's body. The detected values ​​can be communicated to medical staff, or the output of the temperature detection unit can be connected to the control terminals of a high-frequency generator, an amplitude modulation signal generator, and a high-frequency generator. Medical staff can adjust the output of these generators based on the patient's temperature, or the output can be automatically adjusted using a step-by-step method to ensure treatment safety.

[0050] This invention utilizes a high-frequency electric field generated by electrodes to act non-contactly on the tumor area, which can change the temperature of the affected area, or interfere with the formation of tumor cell microtubules, interfere with the stability of membrane proteins, guide dielectrophoresis, inhibit tumor cell migration and invasion, and activate the immune microenvironment, thereby achieving a more natural and efficient bioelectric field therapy effect.

[0051] The treatment device of the present invention can significantly improve tumor pain, swelling, and the patient's mental state, and eliminate bone metastases, with a total effective rate of 100%.
