[0036] The following is combined with Figures 1-3 Specific embodiments of the present invention are described below.

[0037] This invention provides a flexible radio frequency device based on wireless transmission. The device includes two independent units: a flexible radio frequency generator and a flexible radio frequency receiver. The flexible radio frequency generator and the flexible radio frequency receiver transmit radio frequency signals through coil induction, thereby realizing flexible radio frequency based on wireless transmission.

[0038] In this embodiment, the flexible radio frequency generator includes a liquid metal coil 2 encapsulated in a silicone tube. The liquid metal coil 2 encapsulated in the silicone tube is connected to a radio frequency power supply 3 via a wire. The radio frequency power supply 3 provides electrical energy to the liquid metal coil 2 encapsulated in the silicone tube, causing the liquid metal coil 2 encapsulated in the silicone tube to generate a radio frequency magnetic field.

[0039] In some embodiments, the liquid metal coil 2 encapsulated in a silicone tube can be set independently or mounted on a carrier.

[0040] like Figure 1 As shown, in the medical field, in order to make the flexible radio frequency generator close to human tissue, the liquid metal coil 2 encapsulated in silicone tube can be placed on clothing 1, so that the flexible radio frequency generator can be worn on the body for convenient treatment.

[0041] like Figure 2 As shown, in this embodiment, the flexible radio frequency receiver includes a receiving part 4, a radio frequency electrode, a sodium ion-type hydrogel layer 6, and a PBS encapsulation layer 7. The receiving part 4 is a liquid metal coil encapsulated by an elastomer. One end of the receiving part 4 is connected to the radio frequency electrode, which is a liquid metal radio frequency interdigitated electrode 5 encapsulated by a sodium ion-type hydrogel. A sodium ion-type hydrogel layer 6 is provided on one side of the radio frequency electrode, and PBS encapsulation layers 7 are provided on both sides of the receiving part 4.

[0042] In this embodiment, the flexible radio frequency (RF) generator wirelessly transmits RF energy to the flexible RF receiver, which receives the RF energy and converts it into heat energy. The RF signal is transmitted between the flexible RF generator and the flexible RF receiver via coil induction, achieving flexible RF based on wireless transmission. The flexible RF receiver has high tensile strength and flexibility, enabling flexible large-area coverage of tumor lesions and exhibiting good biocompatibility. Based on the principle of radiofrequency ablation, this device uses a sudden high-frequency current (less than 20MHz) to cause ion oscillation within the sodium ion-type hydrogel layer 6, raising the temperature of the layer and converting RF energy into heat energy. This causes coagulative necrosis of tumor cells, thereby eliminating the tumor cells and greatly minimizing damage to surrounding blood vessels and nerves, improving treatment efficacy, and avoiding complications.

[0043] like Figure 2 As shown, in one embodiment, there are multiple receiving units 4, and the multiple receiving units 4 are stacked, with PBS encapsulation layers 7 on both sides of each receiving unit 4.

[0044] In this embodiment, the number of receiving units 4 can be one or more, depending on the actual situation.

[0045] The receiving component 4 is formed layer by layer from liquid metal single-layer coils. The linewidth of the liquid metal single-layer coils in the receiving component 4 is preferably in the range of 100um to 1000um. The line spacing of the liquid metal single-layer coils is preferably in the range of 100um to 1000um, and the thickness is preferably in the range of 100um to 1000um.

[0046] In this embodiment, the sodium ion hydrogel-encapsulated liquid metal radio frequency interdigitated electrode 5 is located at the end of the liquid metal coil of the receiver component 4 and at the center of the flexible radio frequency receiver.

[0047] The preferred linewidth range of the sodium ion hydrogel-encapsulated liquid metal radio frequency interdigitated electrode 5 is 100um to 1000um; the preferred line spacing is 100um to 1000um; and the preferred thickness is 100um to 1000um.

[0048] like Figure 3 As shown, in this embodiment, the PBS encapsulation layer 7 has a groove, and the sodium ion hydrogel layer 6 is embedded in the groove of the PBS encapsulation layer 7 so that one side of the sodium ion hydrogel layer 6 contacts the liquid metal radio frequency interdigitated electrode 5 encapsulated by the sodium ion hydrogel, and the other side is located on the surface of the flexible radio frequency receiver. In this way, during use, the sodium ion hydrogel layer 6 can directly contact the target and can wrap the target area, thereby improving the radio frequency ablation effect.

[0049] Sodium ion-type hydrogel layer 6 has high tensile strength and high flexibility. In the field of tumor treatment, it can achieve flexible large-area coverage of tumor lesions and has good biocompatibility, effectively improving the treatment effect.

[0050] In one embodiment, the total thickness of the sodium ion-type hydrogel layer 6 is 0.1 mm to 2 mm, and the area can be customized according to the growth location and size of the user's tumor to make the radiofrequency generating device different sizes. The conductivity is preferably 2 to 10 S / m.

[0051] In one embodiment, the contact surface between the PBS encapsulation layer 7 and the sodium ion-type hydrogel layer 6 has a porous structure to improve the connection strength between the PBS encapsulation layer 7 and the sodium ion-type hydrogel layer 6.

[0052] It is worth mentioning that PBS encapsulation layer 7 is a chemically synthesized biodegradable material encapsulation layer, whose full Chinese name is polybutylene succinate. It is a new type of biodegradable and environmentally friendly material that ensures that the flexible radio frequency receiver does not produce side effects when placed inside the human body and reduces damage to normal human tissues.

[0053] like Figure 4 As shown, in one embodiment, the flexible radio frequency receiver includes multiple receiving parts 4, multiple radio frequency electrodes, and multiple sodium ion-type hydrogel layers 6. The multiple receiving parts 4 are arranged in an array and correspond one-to-one with the radio frequency electrodes and sodium ion-type hydrogel layers 6. The arrayed flexible radio frequency receiver can increase the treatment area and can be customized according to different tumor locations on the patient's body to treat the tumor location and improve treatment efficiency.

[0054] The flexible radiofrequency device based on wireless transmission provided in this embodiment uses the principle of radiofrequency ablation. By applying a sudden high-frequency current with a frequency of less than 20MHz, the ions in the hydrogel oscillate, the sodium ion-type hydrogel layer heats up, and the radiofrequency energy is converted into heat energy, causing coagulative necrosis of tumor cells, thereby eliminating the tumor cells. Furthermore, by using a flexible wearable device, the impact on daily life during treatment can be greatly reduced. Moreover, the size of the radiofrequency generating device can be customized according to the growth location and size of the user's tumor, which can greatly avoid damage to blood vessels and nerves around the lesion, improve the treatment effect, and avoid the occurrence of complications.

[0069] Step S33: The silicone tube-encapsulated liquid metal coil 2 generates an RF magnetic field.

[0070] Step S34: The elastomer-encapsulated liquid metal RF signal receiving part 4 contained in the flexible RF receiver receives the RF signal, and the elastomer-encapsulated liquid metal RF signal receiving part 4 generates an RF magnetic field, and forms resonance with the external silicone tube-encapsulated liquid metal coil 2 by adjusting the capacitance and inductance.

[0071] Step S35: The liquid metal radio frequency interdigital electrode 5 encapsulated by the sodium ion hydrogel converts the radio frequency magnetic field into radio frequency current, causes sodium ion collision inside the sodium ion hydrogel layer 6, and makes the sodium ion hydrogel layer 6 warm, so that the tumor tissue temperature can be raised to 50-110 DEG C, and the tumor cells can be killed by high temperature, while ensuring that the surrounding normal tissues are not injured.

[0072] The flexible radio frequency device based on wireless transmission provided by the embodiment has the flexible radio frequency generator designed as the liquid metal coil 2 encapsulated by the silica gel tube, and through the combination of the flexible radio frequency generator and the flexible radio frequency receiver, the sodium ion hydrogel layer 6 of the flexible radio frequency receiver has high stretchability and high flexibility, the flexible large-area coating of the tumor lesion can be realized, the sodium ion hydrogel layer 6 has good biocompatibility, the liquid metal radio frequency signal receiving part 4 encapsulated by the elastomer and the liquid metal radio frequency interdigital electrode 5 encapsulated by the sodium ion hydrogel have good flexibility and the ability to generate radio frequency current, and the radio frequency signal can be efficiently received and radio frequency current can be generated.

[0073] The liquid metal coil 2 encapsulated by the silica gel tube is sewn on the clothing 1 with appropriate size, the flexible radio frequency receiver is arranged in the area of the human body which needs to be treated, and the flexible fitting of the human tissue and the efficient transmission of the radio frequency signal are comprehensively realized. The transmission of the radio frequency signal is realized through the coil induction between the flexible radio frequency generator and the flexible radio frequency receiver, the flexible radio frequency based on wireless transmission is realized, and finally the radio frequency ablation treatment of the tumor is realized.
