Treatment head and RF beauty device host are also possible to integrated, and treatment head can be located at the one of RF beauty device host at this time
End, treatment head can be made replaceable, also can be made non-exchange.
It can be monopolar radio frequency that treatment head, which exports radio frequency method, or bipolar radio frequency or multi-pole rf include a little
Battle array radio frequency, for electrode arrangements mode also there is no limit, generally, for monopolar radio frequency, skin treatment area is main
Positioned at electrode and skin contact region, for its treatment region of bipolar radio frequency in addition to electrode and skin contact region further include electrode
Between skin area, multi-pole rf itself is the mutation or extension of bipolar radio frequency, its treatment region is similar with bipolar radio frequency.
The temperature sensor for the treatment of head can be contact such as thermistor, be also possible to non-contacting such as infrared sensing
Device carry out temperature measurement, it is contemplated that treatment head may move on the skin, using thermometric fast speed temperature sensor energy and
The temperature of the current measured skin of Shi Fanying.
The corresponding treatment region of the electrode for the treatment of head is divided according to temperature sensor number, each temperature sensor
Position or each temperature sensor measurement position and the region after division center correspond；For the ease of retouching
It states, lower face handle skin all areas in need for the treatment of are known as whole treatment region, and sometime treatment head radio-frequency electrode can be controlled
The skin area treated is known as electrode therapy region, bipolar radio frequency or multi-pole rf electrode it is adjacent between treatment region call
Subregion is treated, for bipolar radio frequency mode, two electrodes constitute an electrode pair, for the electrode to its skin treating sub-district

Maximum temperature limit reflects the electrode to the therapeutic state of skin, for that can share some between bipolar radio frequency Different electrodes pair
Electrode does not influence the position of temperature sensor；For multi-pole rf, multi-pole rf essence is also bipolar radio frequency, when between electrode
When treating subregion number more than temperature sensor number, such as lattice radio frequency, there are many lesser treatments under normal circumstances
Region, it is assumed that there are N number of temperature sensors, and it is close adjacent lesser treatment subregion can be combined to form N number of size
Combined therapy region, then each combined therapy regional center position place temperature sensor, or place temperature sensor
It is allowed to measured zone and is located at combined therapy regional center position.
Be mapped by overhead temperature sensor and radio-frequency electrode and treatment subregion or therapeutic combination region, i.e., some
Specific temperature sensor corresponds to a piece of specific skin treatment area, which corresponds to one or more radio frequencies again
Electrode, for ease of description, the one or more radio-frequency electrode are known as the correspondence radio-frequency electrode group of the temperature sensor；General feelings
The corresponding one or more radio-frequency electrodes of a temperature sensor are considered under condition, naturally it is also possible to consider that multiple temperature sensors are corresponding
One or more radio-frequency electrodes, only this mode implementation complexity is big and relatively subtle with respect to the former improvement below.
Each temperature sensor ceaselessly measures temperature during RF therapy, and by each temperature feedback to control template,
Control module adjusts the radio frequency parameter that radio-frequency module is input to each corresponding radio-frequency electrode group, radio frequency parameter packet according to temperature value
It includes and is not limited to radio-frequency power, RF phse, rf frequency etc.；It is a kind of that optionally simply way is when some temperature sensor measurement
To temperature reach or when beyond target temperature, be shut off the radio-frequency power output of the corresponding radio-frequency electrode group of the sensor；When
More complicated temperature control algorithm can also be so used, such as on above-mentioned temperature control logical foundations, if some measured temperature
More than one higher temperature threshold values then close all radio-frequency power outputs, and temperature controlled logic can be each treatment region
It is independent to combine consideration.
A kind of way of extension is less than temperature sensor number and controls when radio-frequency electrode and its treatment region are grouped
When treating subregion or areal is treated in combination, it can virtually exceed the temperature sensor of actual number, at this moment there is certain control
Treating regional center position may be without the situation of actual temperature sensor, and the temperature in the region, can pass through other regions at this time
Measured temperature interpolation obtain.
A kind of implemented method of radio-frequency treatment head is that treatment head includes the strip radio-frequency electrode that several are parallel to each other, phase
Adjacent radio-frequency electrode constitutes a radio-frequency electrode pair, and each radio-frequency electrode places a temperature sensor, this realization to centre
It includes three strip radio-frequency electrodes being parallel to each other that fairly simple way, which is treatment head, in method, these three radio-frequency electrodes are constituted
Two radio-frequency electrodes pair, that intermediate electrode are the common electrode of two electrodes pair, and two temperature sensors are located at two
For radio-frequency electrode to the center in the region of composition, Fig. 4 to Figure 12 gives some possible implementation methods for the treatment of head, including adopts
With the modes such as strip radio-frequency electrode mode, circular RF electrode and loop-type radio frequency electrode, lattice radio frequency electrode, but the present invention is complete
Be not limited to these implementation methods, the intension of the invention combined in radio-frequency electrode with temperature sensor be different radio frequency electrode or
Electrode grouping and corresponding temperature sensor constitute multiple temperature control channels or make treated region multiple subregions can it is independent or
Part independent temperature.
Radio-frequency module generally comprises radio-frequency signal source and radio-frequency power amplifier section, for radio-frequency module of the invention, needs
There is the ability for being provided separately different radio frequency electrode group rf power signal, such as a kind of optional method is to provide multiple independent penetrate
Frequency channel, the parameter of each radio-frequency channel such as watt level, phase etc. can be adjusted independently, the corresponding temperature in each radio-frequency channel
Spend sensor and the corresponding radio-frequency electrode group of temperature sensor；If a kind of optional method is to generate a rf power signal, so
Radio-frequency power is applied to by radio-frequency electrode group, the corresponding radio-frequency electrode point of a RF switch by independent RF switch afterwards
Group/temperature sensor, for ease of description, the corresponding radiofrequency signal of one temperature sensor of lower face handle generate, radio-frequency electrode, temperature
Degree measurement and its control circuit become a temperature control channel.
There are radio frequency power output controls for many radiofrequency treatment devices, it is ensured that radiofrequency treatment device corresponds to different skin resistance
