Description
Technical Field
The invention relates to the technical field of photoelectric equipment, in particular to a portable power driving system capable of exciting a multi-frequency ultrasonic and radio frequency treatment head.
Background
In the field of photoelectric equipment for light medical science, the ultrasonic and radio frequency treatment technology is two of the three core technologies (ultrasonic, radio frequency and laser) in the field, the ultrasonic uses a piezoelectric transducer to convert high-frequency excitation voltage into mechanical waves through piezoelectric effect, and then three biological effects of the ultrasonic on a human body, such as mechanical effect, thermal effect and physicochemical effect, are realized, while the radio frequency technology uses the thermal effect of high-frequency current at the epidermis of the human body to achieve the treatment purpose. Therefore, it is possible to try to combine the driving parts of the two, and different treatment modes can be realized by matching different ultrasonic treatment heads or radio frequency treatment heads by adopting the same power excitation device, but after combining the driving parts, because the volume of the portable device is limited, if the driving parts are required to correspond to different treatment heads, because the parameters of the components are inconsistent, and the resonant frequency is related from 200KHz to 5MHz, impedance matching circuits related to multiple frequencies are required to be corresponding, otherwise, the efficiency output efficiency is seriously attenuated or seriously exceeds the standard, the design requirement is not met, and if the impedance matching circuits are designed for each radio frequency head and each ultrasonic head, the area of the circuit board cannot be realized through the volume of the portable device. More importantly, even though the application parts with the same nominal specification are applied, the actual electrical impedance characteristics are inconsistent due to the process difference, even if the same impedance matching circuit is adopted, the best matching effect is difficult to achieve, and the application parts of the matching circuit and the treatment head are required to realize one-to-one pairing to be the optimal scheme. Furthermore, if a rf head or an ultrasonic head is to be newly added, it is not realized with the existing matching circuit, and the impedance matching section must be redesigned. Patent document CN201821997018.8 discloses an intelligent wearable ultrasonic physiotherapy instrument, which cannot solve the technical problem of power driving of a multi-frequency treatment head. Therefore, it is needed to provide a portable power driving system capable of exciting the multi-frequency ultrasonic and radio frequency treatment head, which solves the technical problem of how to realize the power driving of the multi-frequency treatment head.
