[0034] It is easy to understand that according to the technical solution of the present invention, without changing the essence of the present invention, those of ordinary skill in the art can propose various structural forms and implementation manners that can be mutually replaced. Therefore, the following detailed implementation manners and the accompanying drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as all of the present invention or as a limitation or restriction on the technical solution of the present invention.

[0035] As Figure 1 shown, this embodiment introduces a radio frequency energy adjustment method, which includes the following steps:

[0036] S1. Obtain the historical temperature of the square areas divided by specifications such as the treatment range, and arrange the historical temperatures of each square area in ascending order of gradient, and then locate the square area where the gradient start end is located and use it as the target square area for heating.

[0037] For the convenience of the next adjustment, each heating will be recorded, especially the final temperature, and the heating strategy will be adjusted based on the currently measured temperature and the historical temperature during the next heating.

[0038] S2. Obtain the temperatures of the adjacent square areas of the target heating square area in real time, calculate the temperature difference with the adjacent square areas, arrange the adjacent square areas in descending order of temperature difference gradient, and use this gradient as the heating priority sequence.

[0039] Calculation of the temperature difference of each square area: ΔT = T 目标 - T 当前 , T 目标 represents the target temperature of the square area, T 当前 represents the current temperature of the table area, and the unit with a large temperature difference is preferentially heated.

[0040] Distributed control: The heating frequency of each square unit can be controlled according to the following formula: f 加热 = α × ΔT + β;

[0041] Among them, α and β are adjustment coefficients for controlling the heating frequency.

[0042] S3. Calculate the compensation value by weighted calculation of the current temperature of the target heating block area and the current temperature of the adjacent block area, and adjust the heating frequency of the current block area through the compensation value.

[0043] Adopt the adjacent block heating strategy. By analyzing the temperature gradient, for the blocks with lower temperature, the heating frequency of the adjacent blocks can be adjusted. That is:

[0044] Influence weight of adjacent temperature: Wadjacent = ∑λ × (T 当前 - T 邻近 )

[0045] Calculate a compensation value through the weighted average of the adjacent block temperatures, and adjust the heating frequency of the current block. Among them, λ represents the weight coefficient, T 当前 represents the current temperature of the target heating block area, and T 邻近 represents the temperature of the adjacent block area of the target heating block area.

[0046] S4. Real-time collect the temperature of the target heating block area, calculate the difference from the preset target temperature, dynamically adjust the temperature rising rate according to the temperature difference, and make the target heating block area smoothly rise to the target temperature according to the adjusted heating frequency. The temperature rising rate R 上升 = γ × (T 目标 - T 当前 ) + δ, where T 目标 represents the target temperature of the target heating block area, T 当前 represents the current temperature of the target heating block area, and γ and δ represent the rising rate adjustment parameters.

[0047] The radio frequency energy adjustment method of this embodiment can adjust the heating strategy based on the currently measured temperature and historical temperature, so that the heating rising temperature can smoothly reach the target temperature and reduce violent fluctuations.

[0048] Embodiment 2

[0049] As Figure 3 shown, this embodiment introduces an automated device for radio frequency energy fat reduction, which mainly consists of an automatic exercise unit 1, a fixing mechanism 2, an auxiliary fixing bracket 3, and a treatment host 4.

[0050] As Figure 4 shown, the automatic exercise unit 1 includes a treatment electrode 11, a frame 12, and a three-axis slide rail. Define the length direction of the frame 12 as the X direction, the width direction as the Y direction, and the height direction as the Z direction. Slots are opened on both symmetric sides at the top of the frame 12, and a three-axis slide rail is installed on the frame 12.

[0051] Two linkage motors 16 are installed on the edge of the frame 12, and the linkage motors 16 can be fixed by bolts and other parts. The linkage motors 16 are connected by belts, that is, corresponding pulleys are provided on the X-axis slide rail 13 and the Y-axis slide rail 14, and the two share a belt through the cooperation of the pulleys. The two drive motors rotate at the same speed in the same direction, rotate at the same speed in the opposite direction, and rotate at a differential speed, corresponding to the Y direction, X direction and oblique movement respectively. The height motor 17 is installed on the Y-axis slide rail 14, and is connected to the treatment electrode 11 through the Z-axis slide rail 15. That is, a rack is provided on the inner side of the Z-axis slide rail 15, and the output shaft of the height motor 17 is connected to the gear, and the gear is meshed with the rack. The height motor 17 starts to drive the Z-axis slide rail 15, thereby realizing the adjustment of the height of the treatment electrode 11.

[0052] In order to facilitate the control of the height motor 17 and the linkage motor 16, a corresponding motion controller is provided on the frame 12. In addition, in order to sense the temperature generated by the treatment electrode 11 in real time, a temperature sensor for sensing the treatment area is provided on the frame 12.

[0053] like Figure 5 and Figure 6 As shown, the fixing mechanism 2 mainly includes an arc track 21, an auxiliary frame 22, a binding rope 23 and a binding garment 24. The two arc tracks 21 are arranged side by side, and the spacing between the arc tracks 21 is greater than the length of the frame 12. The auxiliary frame 22 is located between the two arc tracks 21, extends outwardly toward one side of the arc track 21 and fits with the arc track 21, and is slidably arranged on the outer surface of the arc track 21 in a concave-convex matching manner, and the frame shape of the auxiliary frame 22 is adapted to the frame 12. That is, the frame 12 can be placed in the auxiliary frame 22. In order to assist the frame 12 to be quickly placed in the auxiliary frame 22, the edge of the auxiliary frame 22 is provided with a positioning hole, and the bottom of the frame 12 side is provided with a positioning pin matching the positioning hole. The top corners of the auxiliary frame 22 are concave-convexly engaged with the bottom corners of the frame 12.

[0054] In order to further fix the frame 12 on the auxiliary frame 22, the symmetrical edges of the auxiliary frame 22 are provided with binding ropes 23, which are clamped in the clamping slots of the frame 12 to achieve the purpose of fixing; the binding garment 24 is worn on the patient to relatively fix the fixing mechanism 2 on the patient, and the binding garment 24 is detachably adhered to the inner wall of the arc track 21. Preferably, the inner wall surface of the arc track 21 is connected with equidistantly distributed Velcro, and the surface of the binding garment 24 is adhered to the Velcro, which is easy to operate.

[0055] The automatic movement unit 1 slides on the arc track 21 so as to be able to slide to the designated treatment area. After the automatic movement unit 1 reaches the designated treatment area, the automatic movement unit 1 also needs to be relatively fixed on the arc track 21. Therefore, a toothed track is arranged on the outer arc surface of the arc track 21 along its edge trajectory, and a cam brake 25 is arranged at the position where the auxiliary frame 22 abuts against the toothed track, and is used to engage with the toothed track to limit the relative position of the auxiliary frame 22 and the arc track 21. In actual application, the cam brake 25 is arranged at the extended position (acting as a slider) of the auxiliary frame 22. Press down the cam brake 25 to press down the rack and engage with the toothed track to achieve the braking purpose.

[0056] As Figure 7 shown, the auxiliary fixing bracket 3 includes a frame 31, a weight reducer 32 and a hook 33. Universal wheels with a braking function are arranged at the bottom of the frame 31, which is convenient for the frame 31 to move to the side of the treatment bed where the patient is located. A horizontally sliding weight reducer 32 is arranged at the top of the frame 31, that is, there is a slide rail at the top of the frame 31, a slider is built in the slide rail, and the weight reducer 32 is installed on the slider. A hook 33 is tied to the movable end of the weight reducer 32; and is used to hang on the hanging ring at the center of the top of the frame 12. Starting the weight reducer 32 to take in the rope can share the weight of the automatic movement unit 1 and reduce the discomfort of the patient.

[0057] The treatment host 4 is used to be responsible for the output of the radio frequency power supply, setting treatment parameters and real-time monitoring of the treatment process, and adjusting the radio frequency energy during the treatment process, and the steps of the radio frequency energy adjustment method as described above are adopted during the adjustment.

[0058] As Figure 2 shown, the overall working process is as follows: The therapist draws the treatment area on the patient's treatment site; the patient first puts on the binding clothes 24 and lies on the treatment bed, and the binding clothes 24 are fixed on the fixing mechanism 2; the automatic movement unit 1 (i.e., the treatment module) is fixed through the auxiliary frame 22, the frame 12 and the binding rope 23; move the position of the automatic movement unit 1 on the auxiliary fixing bracket 3, and use the hook 33 of the weight reducer 32 to hang on the hanging ring of the automatic movement unit 1; the therapist starts the machine and sets the treatment parameters, and the machine can automatically start the treatment until the treatment ends. During the treatment process, if it is in the heating-up stage, global temperature recording and analysis are carried out, and the regional heating priority is updated in real time. When driving the linkage electrode to work, closed-loop control of the temperature rise rate and heating frequency control are carried out through the temperature difference, so as to make the temperature rise steadily. After reaching the target temperature, the path is adjusted in real time according to the temperature difference, and the height motor 17 and the linkage motor 16 are driven to make the treatment electrode 11 move along the path. If there is a phenomenon of rapid temperature rise, overheat protection is carried out, that is, the radio frequency output is cut off and the heating is paused during rapid temperature rise.

[0059] The technical scope of the present invention is not limited to the content described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of the present invention, and these deformations and modifications shall fall within the protection scope of the present invention.
