There are many current approaches to managing bone loss due to bone fracture, and electromagnetic therapy is one of them. Treatment of bone fractures with pulsed electromagnetic fields has been known for many years. In 1979, the pulse electromagnetic field is approved by the FDA to be used for the auxiliary treatment of clinical bone diseases such as osteoporosis, osteoarthritis and the like, and has been widely accepted by the medical community at home and abroad. The pulse electromagnetic field and ultrasonic shock wave treatment are the known effective fracture physical treatment methods in the fracture physical treatment guidance published by the American orthopedic society. Therefore, the method for promoting fracture healing by using the pulsed electromagnetic field is applied to the clinic in China, America, Italy, the Netherlands, Singapore and the like, and better treatment and rehabilitation effects are achieved. However, the conventional dynamic electromagnetic field bone treatment instrument has a single structure, cannot perform matching treatment according to the type of bone loss caused by fracture, and a load coil generating a dynamic magnetic field can only be matched with a fixed frequency from a power amplifier, so that the condition of power loss of a load coil caused by incomplete power matching occurs in most cases, and the treatment effect is further influenced.

Those skilled in the art will appreciate that the terminal structure shown in fig. 1 is not intended to be limiting and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.
As shown in fig. 2, fig. 2 is a schematic flow diagram of a first embodiment of a frequency adaptive control method according to the present invention, and in this embodiment, the method includes:
step S10, receiving the input initial parameters;
before receiving initial parameters input by related personnel, the natural frequency of the load coil needs to be acquired, and the natural frequency of the load coil is used as partial parameters of the initial parameters and is manually input by the related personnel or is automatically input to a parameter input module in the frequency adaptive control system after the natural frequency of the load coil is acquired by the frequency adaptive control system.
The initial parameters at least comprise an initial radio frequency signal frequency, a preset sweep frequency bandwidth and a preset sweep frequency point number, and the initial radio frequency signal frequency is equal to the natural frequency of the load coil. The natural frequency of the load coil is a theoretical frequency of the load coil obtained by calculation from coil parameters such as the shape and winding form of the load coil and the number of strands of the coil.
The coil parameters determine the signal frequency of the load coil, the actual frequency of the processed load coil has a certain difference from the theoretical frequency in the coil simulation calculation, and meanwhile, the actual frequency of the processed load coil also has a difference in the actual application environment. This is the root cause of the large loss of signal power from the load coil when the rf signal from the signal generation module, which is emitted according to the theoretical frequency of the load coil, is transmitted to the load coil.
On the one hand, the load coil can be designed according to the specificity of the surface and structure on which the load coil acts, so that after the conventional dynamic magnetic field generating device is replaced by a new load coil, because the frequency signal generated by the signal generating module in the conventional dynamic magnetic field generating device is a fixed frequency signal (the theoretical frequency of the load coil), the frequency of the signal transmitted by the signal generating module may not be completely matched with the frequency of the load coil, and further the signal power of the load coil is lost.
On the other hand, even if the load coil is not replaced with a new one, the signal frequency of the load coil is very easily affected by other conditions such as an external magnetic field environment, so that the signal frequency of the load coil is always in a fluctuating state, which causes a loss of the signal power of the load coil to be difficult to avoid.
Step S20, outputting an initial radio frequency signal to a load coil according to the initial parameters;
specifically, the step S20 includes:
a, dividing the preset sweep frequency bandwidth into signal frequency bands with the same number as the preset sweep frequency points according to the preset sweep frequency points;
b, roughly scanning the signal frequency band by taking the initial radio frequency signal frequency as a center to obtain an initial radio frequency signal;
and c, outputting the initial radio frequency signal to a load coil.
It should be noted that the preset sweep bandwidth and the preset sweep number may be set and input according to actual needs. The initial parameters correspond to the preferred ranges:
the frequency range of the initial rf signal frequency is: 0.1 Hz-3 GHz;
the preset sweep bandwidth range is as follows: 0.1 Hz-1 GHz;
the preset sweep frequency point number range is as follows: 1-10000 pieces.
In the preset sweep frequency bandwidth range, the sweep frequency bandwidth is divided into signal frequency bands with the same number as the number of sweep frequency points according to the number of the sweep frequency points, then left and right sweep frequency is carried out in the preset sweep frequency bandwidth range by taking the frequency of an initial radio frequency signal (the theoretical frequency of a load coil) as a central frequency, and a discontinuous frequency range can be output in the left and right sweep frequency process: the initial radio frequency signal of 0.1 Hz-3 GHz, specifically, the boundary point of each segmented adjacent signal frequency band is used as a boundary, and the output of the initial radio frequency signal is not output or interrupted within a short time preset on the boundary, so that the discontinuous initial radio frequency signal can be output and visually presented to distinguish different signal frequency bands, and the judgment of the corresponding signal frequency band of the initial radio frequency signal when the signal voltage reflected by the load coil is minimum is facilitated. And finally, transmitting the initial radio frequency signal to a load coil.
In one embodiment, the step S30 includes:
d, determining a target reflection signal with the minimum voltage value in the reflection signals;
and e, adjusting the initial parameters according to the target reflection signal so as to enable the initial radio frequency signal and the frequency of the load coil to be in a resonance state.
In this embodiment, since the initial rf signal corresponds to a certain frequency range, the reflected signal fed back based on the initial rf signal also corresponds to a certain frequency range, i.e. the reflected signal here is not a signal of fixed frequency. But rather a collection of individual signals of a range of frequencies.
The voltage values of the signals with various frequencies in the reflected signals can be monitored in real time through the signal monitoring module, and the magnitude comparison of the values of the voltage values of the signals in the reflected signal set is carried out, so that the target reflected signal with the minimum voltage value in the reflected signals is determined.
Specifically, the step of determining the target reflection signal with the smallest voltage value in the reflection signals includes:
acquiring voltage values of all signals in the reflected signals;
and comparing the voltage values of the signals to determine a signal with the minimum voltage value in the reflected signals, and taking the signal with the minimum voltage value as a target reflected signal.
Because the magnitude of the reflected power is in positive correlation with the monitored voltage value of the reflected signal, a fitting relationship between the magnitude of the reflected power and the monitored voltage value of the reflected signal is obtained through a certain algorithm, and the target reflected signal with the minimum voltage value in the reflected signal is determined, so that the load coil can maximally absorb all signal power of the initial radio-frequency signal, namely, the frequency of the load coil and the frequency of the initial radio-frequency signal are in a resonance state.
In this embodiment, by determining the target reflection signal with the minimum voltage value in the reflection signals, it can be efficiently and inexpensively determined whether the frequencies of the initial radio frequency signal and the load coil are in a resonance state, and further, the initial parameters are adjusted to adaptively fix the initial radio frequency signal at the same frequency as the frequency of the load coil, thereby reducing the loss of the output power of the load coil to the maximum extent.
Step S30, obtaining a reflected signal fed back by the load coil based on the initial radio frequency signal;
when the initial radio frequency signal reaches the load coil, the load coil generates a dynamic magnetic field, and in general, the load coil cannot completely absorb the initial radio frequency signal, and because the signal frequency of the load coil or the frequency of the generated dynamic magnetic field is often inconsistent with the frequency of the initial radio frequency signal, a part of the radio frequency signal, namely a reflected signal, is reflected.
And step S40, adjusting the initial parameters according to the reflected signals to enable the initial radio frequency signals and the frequency of the load coil to be in a resonance state.
And determining a target reflection signal with the minimum voltage value in the reflection signals, thereby tracing the source and then determining the output frequency corresponding to the initial radio-frequency signal generating the reflection signals, taking the output frequency as a new initial parameter and keeping the initial parameter, so that the initial radio-frequency signal and the frequency of the load coil can be in a resonance state, namely, the frequency of the initial radio-frequency signal is matched with the frequency of the load coil in an equal manner.
For a more intuitive understanding of the present embodiment, reference may be made to fig. 3 for a specific description, and fig. 3 is a schematic diagram illustrating an example of a structure of a frequency adaptive control device according to a first embodiment of the frequency adaptive control method of the present invention.
As shown in fig. 3, the frequency adaptive control device may include a signal generating module, a power amplifying module, a signal coupling module, a load terminal, a signal monitoring module, and a parameter input module, wherein the load terminal includes a load coil.
The method comprises the steps that firstly, related personnel input initial parameters in a parameter input module according to theoretical frequency obtained by calculation of a load coil, then the initial parameters are transmitted to a signal generation module, the signal generation module is used for outputting initial radio frequency signals for a frequency self-adaptive control system according to the initial parameters, and the output initial radio frequency signals are directly transmitted to a power amplification module. The power amplification module amplifies the power of the initial radio frequency signal, the amplified initial radio frequency signal is transmitted to the signal coupling module, the initial radio frequency signal processed by the signal coupling module is transmitted to a coil winding (load coil) in a load end, the load coil can reflect the signal according to the initial radio frequency signal, the reflected signal is transmitted to the signal monitoring module through an isolation end of the signal coupling module, the signal monitoring module monitors the voltage value of each signal in the reflected signal, the signal monitoring module is further used for monitoring the initial radio frequency signal output by the signal generation module, and finally the initial parameter in the parameter input module is adjusted according to the voltage value result monitored by the signal monitoring module.
Specifically, the frequency of the output radio frequency signal is controlled by the parameter input module according to the voltage information acquired by the signal monitoring module, so that the frequency of the output signal of the radio frequency signal generation module is consistent with the frequency of a load end (receiving coil);
specifically, the power amplification module performs power amplification on the initial radio frequency signal generated by the signal generation module according to a preset multiplying power, wherein the preset multiplying power is set according to actual needs;
the load coil in the load end is matched with the frequency of the initial radio frequency signal output by the signal coupler, and if the load coil is in a non-resonance state, the load coil in the load end can reflect unabsorbed signal power to the signal coupling module;
the parameter input module is used for setting parameters of the radio frequency signal generation module, receiving voltage data from the signal monitoring module and specifically adjusting the signal output frequency of the radio frequency signal generation module.
The frequency self-adaptive control method can enable the signal generation module to send out ideal regular radio frequency signals corresponding to all parameters according to all the input parameters through the step of receiving the input initial parameters and the step of outputting the initial radio frequency signals to the load coil according to the initial parameters, and can monitor and obtain the reflected signals fed back by the load coil in real time through the step of obtaining the reflected signals fed back by the load coil based on the initial radio frequency signals. The step of adjusting the initial parameters according to the reflected signals to enable the initial radio-frequency signals and the frequency of the load coil to be in a resonance state enables the signal generation module to dynamically and automatically adapt and match the frequency of the load coil, so that the frequency of the radio-frequency signals sent by the signal generation module and the frequency of the load coil are always in a resonance state, the signal power output of the load coil can be greatly enhanced, and the radio-frequency radiation effect on the bone tissue lesion part is improved.
Further, a second embodiment of the frequency adaptive control method of the present invention is proposed based on the first embodiment of the frequency adaptive control method of the present invention, and in this embodiment, the step of adjusting the initial parameter so that the initial radio frequency signal and the frequency of the load coil are in a resonance state according to the target reflection signal includes:
step g, determining a target radio frequency signal in the initial radio frequency signal according to the target reflection signal;
h, determining the target radio frequency signal frequency corresponding to the target radio frequency signal;
and i, taking the target radio frequency signal frequency as the initial parameter, and outputting the initial radio frequency signal to the load coil according to the initial parameter so as to enable the frequency of the initial radio frequency signal and the frequency of the load coil to be in a resonance state.
Because each frequency signal in the reflected signals has the corresponding initial radio frequency signal, that is, the target radio frequency signal in the plurality of initial radio frequency signals, can be further determined through the target reflected signal, so as to obtain the signal frequency corresponding to the target radio frequency signal, the signal frequency is used as a new initial parameter to replace the original initial parameter to output the initial radio frequency signal, when the initial radio frequency signal and the frequency of the load coil are in the non-resonance state, the initial radio frequency signal is output again according to the unchanged initial parameter in the first embodiment, and the frequency of the load coil can be subjected to adaptive matching again.
In one embodiment, the step of determining the target rf signal in the initial rf signal according to the reflected signal includes:
step j, determining a target signal frequency band corresponding to the target reflection signal according to the target reflection signal;
and k, performing fine scanning on the target signal frequency band to determine a target radio frequency signal in the initial radio frequency signals.
In this embodiment and the previous embodiment, the reflected signal includes a target reflected signal with a minimum voltage value, and because of the coarse scanning, the target reflected signal with the minimum voltage value cannot be completely determined theoretically, and the target radio frequency signal corresponding to the target reflected signal with the minimum voltage value and the frequency of the target radio frequency signal cannot be directly determined, but because the scanning is performed in a segmented manner in the preset scanning bandwidth in the above embodiment, the segmented frequency of the target reflected signal can be determined, and further, the target signal frequency band of the target radio frequency signal can be determined, the efficiency of locating the target signal frequency band of the target radio frequency signal can be rapidly improved by bisection in the segmented scanning process, and the fine scanning is performed after the target signal frequency band is determined, so that the target radio frequency signal can be found from the target signal frequency band, and the frequency of the target radio frequency signal is the actual frequency of the load coil, therefore, the frequency self-adaption is realized, the signal power loss of the load coil is reduced, the loss of the strength of a dynamic magnetic field generated by the load coil is greatly reduced, and the radio frequency radiation effect on the bone tissue lesion part is ensured.
In an embodiment, the step of performing a fine scan on the target signal frequency band to determine the target rf signal in the initial rf signals includes:
and step l, performing fine scanning on the target signal frequency band, and determining a target radio frequency signal in the initial radio frequency signal according to a signal monotonicity rule.
Specifically, fine scanning is carried out in a target signal frequency band, monotonicity of initial radio frequency signals in the target signal frequency band is judged, and if some initial radio frequency signals have monotonicity, the frequency of the initial radio frequency signals is not a frequency point which enables power signals of a load coil to be reflected to be minimum; if the initial radio frequency signal of a certain frequency is not monotonous, the frequency is a frequency point which enables the power signal of the load coil to reflect the minimum, and therefore the initial radio frequency signal of the frequency is determined as the target radio frequency signal in the initial radio frequency signal.
