Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0045] In one embodiment, see the attached Figure 1 , attached Figure 1 One of the structural schematic diagrams of the treatment device 100 in an embodiment of the present application is shown. The treatment device 100 in this embodiment includes an antenna module 110, a detection module 120 and a control module 130. The antenna module 110 is connected to the detection module 120, and the control module 130 is connected to the detection module 120; the detection module 120 is used to connect to the signal source 210, and send the detection signal emitted by the signal source 210 to the antenna module 110; the antenna module 110 is used to emit a radio frequency signal acting on the target object 310 according to the detection signal; the detection module 120 is also used to obtain the impedance matching parameters between the antenna module 110 and the target object 310 according to the detection signal and the reflected signal reflected back by the target object 310 from the radio frequency signal; the impedance matching parameters include voltage standing wave ratio or return loss; the control module 130 is used to connect to the signal source 210, and control the signal source 210 to emit the treatment signal when the impedance matching parameters meet the preset conditions.
[0046] The signal source 210 is a device capable of emitting energy signals, such as a microwave signal source. Accordingly, both the treatment signal and the detection signal can be microwave signals, and the treatment signal and the detection signal have different frequencies. Alternatively, the signal source 210 can be a microwave signal source and an ultrasonic signal source. Accordingly, the detection signal can be a microwave signal and the treatment signal can be an ultrasonic signal, but the present invention is not limited thereto.
[0047] The antenna module 110 may be any antenna capable of transmitting microwave signals, for example, it may be a component / module of a directional narrowband antenna. The directional narrowband antenna may include a component of a waveguide antenna, a multi-frequency antenna, a dual-frequency antenna, a single-frequency antenna, etc. It is understandable that in order to achieve stable signal transmission, different antennas may also be equipped with corresponding accessories, for example, a waveguide antenna is connected to the signal source 210 via a coaxial interface, and the impedance matching state between the waveguide antenna and the target object 310 is calibrated by an impedance matching device, etc., but is not limited thereto.
[0048] The detection module 120 may be a circuit capable of signal transmission and signal analysis and processing, capable of transmitting the detection signal to the antenna module 110, and capable of transmitting the reflected signal fed back by the target object 310 to the control module 130 after conversion processing. Specifically, the reflected signal may be converted into a corresponding impedance matching parameter, so that the control module 130 further judges the impedance matching parameter. When the impedance matching parameter satisfies the preset condition, it is judged that the fit between the antenna module 110 and the target object 310 is ideal, and the signal source 210 is controlled to output a treatment signal. The preset condition may be the degree of matching between the output impedance of the signal source 210 and the input impedance of the treatment device 100 when the fit between the antenna module 110 and the target object 310 is ideal, for example, the output impedance of the signal source 210 may be equal to the input impedance of the treatment device 100, or may be equivalent to the corresponding parameter when the two are equal within a certain error. The impedance matching parameter may be characterized by voltage standing wave ratio and return loss.
[0049] In this embodiment, by achieving impedance matching between the antenna module 110 and the target object 310, energy transmission can be maximized and energy loss can be reduced, thereby improving the overall performance of the wireless communication system. Impedance matching can be achieved by a variety of methods, including matching using components such as capacitors, inductors, resistors, or tuning screws, transmission line matching, etc. When the impedance matching is good, the reflected signal is small, otherwise it is large.
[0050] It is understandable that the following problems may exist when using a contact sensor to detect the degree of fit between the target object 310 and the antenna module 110: the response time of the pressure sensor is long and it is not possible to reflect the change in skin fit in real time; secondly, the sensor needs to be placed between the probe and the skin, which not only increases the complexity of the operation, but also may affect the efficiency of the transfer of treatment energy, thereby affecting the treatment effect. In this embodiment, the impedance matching parameters between the antenna module 110 and the target object 310 are obtained by the detection module 120, and the degree of fit between the target object 310 and the antenna module 110 is characterized by the impedance matching parameters. Compared with the detection using a contact sensor, the fit detection can be realized quickly and in real time. The control module 130 ensures that the emission of the treatment signal is controlled when the impedance matching parameters meet the preset conditions, that is, the treatment is performed only when the fit between the antenna module 110 and the target object 310 meets the conditions, thereby ensuring the treatment effect of the treatment device 100 and the safety of the treatment process.
[0051] In one embodiment, see the attached Figure 2 , attached Figure 2A structural schematic diagram of a detection module 120 in an embodiment of the present application is shown. The detection module 120 in this embodiment includes a transceiver unit 121, a signal separation unit 122 and a signal processing unit 123; the transceiver unit 121 is used to connect to the signal source 210, and is respectively connected to the signal processing unit 123 and the signal separation unit 122, for receiving a detection signal and a reflection signal, and detecting the power of the detection signal and the reflection signal; the signal separation unit 122 is configured with a first port, a second port and an output end, the first port of the signal separation unit 122 and the second port of the signal separation unit 122 are both connected to the transceiver unit 121, the first port of the signal separation unit 122 receives the detection signal, the output end of the signal separation unit 122 is connected to the antenna module 110, for receiving the reflection signal, and the second port of the signal separation unit 122 is used to transmit the reflection signal to the transceiver unit 121; the signal processing unit 123 is used to obtain the impedance matching parameters between the antenna module 110 and the target object 310 according to the power of the detection signal and the reflection signal.
[0052] In this embodiment, the signal separation unit 122 can separate the detection signal from the reflection signal, receive the detection signal through the first port, and transmit the reflection signal to the transceiver unit 121 through the second port. The transceiver unit 121 can obtain the power of the detection signal and the reflection signal, so that the signal processing unit 123 can obtain the corresponding impedance matching parameters based on the power of the detection signal and the reflection signal. Therefore, the detection module 120 in this embodiment can obtain the corresponding impedance matching parameters in real time according to the detection signal and the reflection signal, and perform fit detection through the impedance matching parameters, which can improve the fit detection efficiency and accuracy of the treatment device 100 and the target object 310.
[0053] In one embodiment, the detection signal comprises a microwave detection signal; the treatment signal comprises a microwave treatment signal; Figure 3 , attached Figure 3The second structural schematic diagram of the therapeutic device 100 in this embodiment is shown, the signal source 210 includes a first microwave signal source 211 and a second microwave signal source 212, the first microwave signal source 211 is connected to the detection module 120, and is used to output a microwave detection signal; the second microwave signal source 212 is connected to the control module 130, and is used to output a microwave therapeutic signal when the impedance matching parameter meets the preset condition; the therapeutic device 100 also includes a selection module 140, the selection module 140 is configured with a first end, a second end, a controlled end and an output end, the first end of the selection module 140 is connected to the detection module 120, and the selection module The second end of 140 is used to connect to the second microwave signal source 212, the controlled end of the selection module 140 is connected to the control module 130, and the output end of the selection module 140 is connected to the antenna module 110. The selection module 140 is used to connect the connection between the detection module 120 and the antenna module 110 under the first control action of the control module 130 to transmit the microwave detection signal to the antenna module 110, and also to connect the connection between the second microwave signal source 212 and the antenna module 110 under the second control action of the control module 130 so that the microwave treatment signal acts on the target object 310 via the antenna module 110.
[0054] In order to match different types of antenna modules 110, the present application also provides a feasible embodiment, in which the detection signal is emitted by the first microwave signal source 211, and the treatment signal is emitted by the second microwave signal source 212. At this time, the detection signal and the treatment signal are different types of microwave signals. The control module 130 controls the selection module 140, such as the microwave switch that conducts the transmission path between the first microwave signal source 211 or the second microwave signal source 212 and the antenna module 110, so that the treatment signal can be controlled to act on the target object 310 when the impedance matching parameter meets the preset conditions. In addition, since microwave signals have the characteristics of fast propagation speed and short response time, the treatment device 100 in this embodiment can not only realize real-time monitoring, but also does not need to place any additional equipment in front of the probe, thereby avoiding the potential impact on the treatment effect, and can significantly improve the accuracy of fit detection and the treatment efficiency and safety, so as to achieve the purpose of integrated detection and treatment and precise treatment.
[0055] In one embodiment, the antenna module includes a dual-band antenna.
[0056] The antenna module in this embodiment can be a dual-frequency antenna, which can be designed to work in close proximity to human skin tissue (i.e., the target object), and impedance matching under both the detection signal of frequency one (such as 5GHz) and the treatment signal of frequency two (such as 5.8GHz). A corresponding first microwave signal source is configured for the detection signal of frequency one, and a second microwave signal source is configured for the treatment signal of frequency two. The transmission line between the first microwave signal source and the second microwave signal source and the antenna module is switched through the selection module, and the return loss of the detection signal of frequency one is read through the control module. If the return loss meets the preset requirements under the detection signal of frequency one, the control module controls the second microwave signal source to output the treatment signal of power two to act on the target object, otherwise the output is prohibited. In this embodiment, the dual-frequency antenna can realize the integration of treatment and detection.
[0057] In one embodiment, the antenna module comprises a directional narrowband antenna.
[0058] In this embodiment, signal transmission is performed through a directional narrowband antenna, which can effectively transmit detection signals, treatment signals, and reflected signals. By utilizing the high gain, high directivity, and good impedance matching characteristics of the directional narrowband antenna, the energy of the detection signal (or detection signal and treatment signal) can be concentrated on the target object, reducing energy loss and interference, and increasing detection accuracy. When it is also used to transmit treatment signals, it can also improve the treatment effect.
[0059] In one embodiment, the directional narrowband antenna includes one of a waveguide antenna assembly, a single-frequency antenna, a dual-frequency antenna, and a multi-frequency antenna.
[0060] For example, taking the single-frequency antenna 111 as an example, see the attached Figure 4 The working schematic diagram of the single-frequency antenna 111 is shown. The single-frequency antenna 111 is designed to work in close contact with human skin tissue, and the impedance matching meets the requirements, and is configured with a microwave signal source 213 of the corresponding frequency. Before treatment, the microwave signal source 213 first outputs a detection signal of a specific power (such as 10mW) for detection, and the control module 130 reads the return loss or voltage standing wave ratio. If the return loss or voltage standing wave ratio meets the preset requirements, the control module 130 allows the microwave signal source 213 to output a treatment signal of a preset power (such as 30W) to act on the target object 310, otherwise the output is prohibited.
[0061] In addition to the above examples, the directional narrowband antenna can also be an end-fire antenna such as a printed Yagi antenna, a two-element array antenna, a four-element array antenna, an eight-element array antenna, or a side-fire antenna such as a microstrip antenna, but is not limited thereto. Figure 5The schematic diagram of the working of the broadside antenna 112 is shown, wherein (a) is a schematic diagram of the broadside antenna 112 and the target object 310 when the fit reaches the requirement, (b) is an equivalent circuit diagram corresponding to (a), Z0 is the impedance of the interface connecting the signal source 210 and the treatment device 100, Z` in The therapeutic device 100 and the signal source (attached Figure 5 The impedance of the connection interface (not shown), Z L is the impedance of the target object 310. (c) is a schematic diagram showing that the fit between the broadside antenna 112 and the target object 310 does not meet the requirements. (d) is an equivalent circuit diagram corresponding to (c), where Z air The impedance introduced when there is an air gap between the antenna module 110 and the target object 310. The above-mentioned side-firing antenna 112 is simulated and designed by simulation software to be close to human skin tissue and have impedance matching. When there is an air gap between the side-firing antenna 112 and the target, it is equivalent to introducing impedance, such as Figure 5 As shown in Figures (c) and (d) in FIG. 1 , the impedance of the target object 310 becomes Z L ', destroying the original matching state and causing the reflection coefficient to deteriorate. Therefore, it is possible to detect whether the antenna module 110 is in contact with the target object 310 through the impedance matching parameters.
[0062] In one embodiment, see the attached Figure 6 , attached Figure 6 The schematic diagram of the structure of the waveguide antenna assembly in this embodiment is shown, wherein (a) is a schematic diagram of the waveguide antenna 1132 and the target object 310 when the bonding meets the requirements, wherein (b) is an equivalent circuit diagram corresponding to (a), wherein (c) is a schematic diagram of the waveguide antenna 1132 and the target object 310 when the bonding does not meet the requirements, and (d) is an equivalent circuit diagram corresponding to (c). The waveguide antenna assembly in this embodiment includes a resonant screw 1131 and a waveguide antenna 1132, and the resonant screw 1131 is respectively connected to the waveguide antenna 1132 and the signal source (attached Figure 6 1132) is connected to the target object 310 and the waveguide antenna 1132 to calibrate the fitting state between the target object 310 and the waveguide antenna 1132 to the target fitting state.
[0063] In this embodiment, based on the impedance matching principle, the target object 310 can be regarded as a load, and the resonant screw 1131 is a matching device, which is used to calibrate the fit state of the target object 310 and the waveguide antenna 1132 to the target fit state, that is, the state when there is no air gap, and the fixed resonant screw 1131 is no longer adjustable. Exemplarily, the partial impedance of the resonant screw 1131 when the fixed resonant screw 1131 is no longer adjustable is recorded as , then the input impedance seen from the end face of the matching device is , voltage reflection coefficient , VSWR ,when ,Right now When the impedance is completely matched, generally speaking A common impedance is 50Ω (or 75Ω), that is, the output impedance of the microwave signal source 213 is usually 50Ω (or 75Ω). Figure 6 As shown in Figure (c) of the figure, an air gap is introduced, which is equivalent to introducing an additional impedance, such as Figure 6 As shown in Figure (d), the load impedance becomes Z L ', destroying the original matching state and causing the reflection coefficient to deteriorate. At this time, the control module 130 can be used to immediately control the treatment signal to stop transmitting to avoid treatment failure.
[0064] In one embodiment, continue to refer to the attached Figure 6 The waveguide antenna assembly also includes a coaxial interface 1133 , which is connected to the waveguide antenna 1132 and is used to conduct the connection between the signal source and the waveguide antenna 1132 .
[0065] In other embodiments, the signal source and the waveguide antenna 1132 may be connected via other types of interfaces, and it is only necessary to ensure a stable connection between the waveguide antenna 1132 and the signal source.
[0066] In one embodiment, see the attached Figure 7 , attached Figure 7 The third structural schematic diagram of the treatment device 100 in this embodiment is shown. The signal source 210 in this embodiment includes a first microwave signal source 211 and a treatment probe 214; the first microwave signal source 211 is connected to the detection module 120 for transmitting a detection signal; the treatment probe 214 is connected to the control module 130 for outputting a treatment signal under the control of the control module 130 when the impedance matching parameters meet the preset conditions.
[0067] The treatment probe 214 can emit treatment signals by itself, and the treatment signals can be microwave signals or ultrasonic signals, etc., but are not limited thereto. In this embodiment, another feasible embodiment is provided. When the signal source 210 includes the first microwave signal source 211 and the treatment probe 214, the treatment energy can be replaced by replacing the treatment probe 214, and the fit detection can be realized by the detection signal emitted by the first microwave signal source 211, so as to ensure that the treatment process is carried out safely and effectively.
[0068] In one embodiment, the antenna module comprises an end-fire antenna.
[0069] The end-fire antenna may be a printed Yagi antenna, a two-element array antenna, a four-element array antenna, an eight-element array antenna, or the like.
[0070] The end-fire antenna in this embodiment can be used in conjunction with the treatment head to avoid the problem of inability to achieve effective treatment due to the small size of the end-fire antenna.
