Technical Field

Background

Puffy fat in the eye (i.e., bags) is caused by excessive fat accumulation in the orbit and thinning and weakening of the eyelid support structure (i.e., the musculus oculi), which has a large aesthetic impact on the face of the patient. The method for removing the eye puffy fat by an operation mode is an effective means for rapidly solving the problem of the eye bags. The conventional methods for removing the swelling fat of the eyes comprise an internal cutting method, an external cutting method, a vacuum liposuction method, a radio frequency method and a laser method for removing the eye bags. Among them, the endo-incision, exo-incision and liposuction are involved in interventional surgical treatment, usually with wounds, long recovery time, and the situation of unsatisfactory surgical effect may exist because the positions and amounts of the tissues to be cut and cut/sucked are all operated by the experience of the surgeon. Although the laser method has no wound, the laser may directly contact with the eyes during the operation process, so that the eyes can be burnt. The radio frequency method is the optimal treatment scheme in the prior art in terms of postoperative recovery and operational safety.

However, the current methods for removing the swelling fat of the eyes by radio frequency have the following problems: 1) the radio-frequency biological heat can cause the dermis of the fibrous septum to tighten, and then the inflammatory reaction after the trauma is started, so that the postoperative edema condition is obvious; 2) the fat distribution is not uniform enough and local skin depressions are likely to occur.

It is to be noted that the drawings are in a very simplified form and are all used in a non-precise ratio for the purpose of facilitating and clearly aiding in the description of the embodiments of the invention.

As shown in fig. 1, the device for removing eye puffy fat provided by the invention comprises a central controller 6, a cooling fluid control part 3, a heating control part 4, a radio frequency control part 5 and a radio frequency handle 1.

Wherein, the central controller 6 is respectively connected with the cooling fluid control part 3, the heating control part 4, the radio frequency handle 1 and the radio frequency control part 5. The central controller 6 is used for receiving a preset program and a temperature feedback signal of a temperature sensor 133 on the radio frequency handle 1; and according to the requirements of the preset program and the temperature feedback signal, corresponding control instructions for the cooling fluid, the heating component and the radio frequency signal are respectively sent to the cooling fluid control part 3, the heating control part 4 and the radio frequency control part 5, so as to realize the control of the corresponding components. The above control is a common setting-feedback control method in the art, and the specific programming method of the control is known to those skilled in the art, and therefore, the detailed description thereof is omitted here. The central controller 6 may be a programmable controller, a single chip or other microcomputer/electronic control device.

The cooling fluid control 3 is connected to a cooling fluid pump which is connected to a cooling fluid circuit which is formed by the cooling fluid pump, the radio frequency handle 1 and a cooling fluid reservoir (not shown). The cooling fluid control part 3 controls the flow rate of the cooling fluid in the cooling circuit according to the instruction of the central controller 6, thereby realizing the control of the surface cooling temperature of the operating head 13 of the radio frequency handle 1.

The heating control part 4 controls the temperature of a plurality of heating parts on the surface of the operating head 13 of the radio frequency handle 1 according to the instruction of the central controller 6, thereby realizing the control of the heating temperature of the operating head 13 of the radio frequency handle 1.

The radio frequency control part 5 controls the radio frequency signals of the three radio frequency output heads 136 of the operating head 13 of the radio frequency handle 1 according to the instruction of the central controller 6.

As shown in fig. 2, the structure of the radio frequency handle 1 in the device provided by the invention is shown. Wherein the radio frequency handle 1 comprises a body having a horizontal portion 11 and a hand-held portion 12. A power line and a signal line are connected to the lower end of the hand-held portion 12, the power line is used for providing electric energy for the radio frequency handle 1, and the signal line is respectively connected with the heating control portion 4 and the radio frequency control portion 5, so that corresponding control signals are respectively transmitted to the heating component on the operating head 13 and the radio frequency output head 136.

The middle of the hand-held portion 12 of the radio-frequency handle 1 is also provided with a control panel 16, and the control panel 16 preferably comprises a circular liquid crystal digital display screen at the center for displaying the setting conditions of basic parameters (such as temperature, radio-frequency, time, cycle times and the like) of the current operation. Touch keys are distributed around the circular liquid crystal digital display screen and used for realizing the functions of selecting, adjusting or modifying the setting.

The rear end of the horizontal part 11 of the radio frequency handle 1 is provided with a cooling fluid interface 14, and the cooling fluid interface 14 is further connected with a cooling fluid input pipe and a cooling fluid output pipe 15. The cooling fluid inlet and outlet pipes 15 extend from the interior of the horizontal portion 11 to the cooling plate of the operating head 13, and allow circulation of the cooling fluid in the cooling zone of the operating head 13.

As shown in fig. 3, fig. 3 shows the structure of the operating head 13 of the radio frequency handle 1, the operating head 13 is a disk shape as a whole, the outermost circle of the disk part is a heating area 131, a plurality of heating elements 132 are distributed inside the heating area 131, preferably, the heating elements 132 are 4-8, more preferably, 8, the heating effect is most uniform, and the cost is not increased obviously. The heating element 132 may be a heat resistive element, such as: resistance wires, micro electric heating plates; but may also be opto-electronic devices such as infrared emitters, infrared diodes.

Inside the annular region enclosed by the heating region 131, 3 rf output heads 136 are provided, and the rf output heads 136 can continuously output rf signals to the fat-swollen portion of the patient, and the frequency of the rf signals is 40.67 MHz. By outputting the radio frequency with the frequency to the position where the eye bulges fat, water molecules in the cells can generate heat through friction, and the heat is transferred to the fat cells, so that the fat cells are gradually melted. By the above-mentioned manner of melting the excess fat, the swollen fat of the eye can be removed.

The 3 rf output heads 136 output rf signals with the same frequency, but the rf signals have different phases and a phase difference exists between the rf signals, so that the energy distribution of the rf signals is more uniform, which is more beneficial to melting the redundant fat more uniformly, and avoiding uneven distribution of fat blocks. Preferably, the 3 rf output heads 136 may be arranged in a triangular shape, and the 3 rf output heads 136 may also be arranged in a column or a row or in other forms.

At blank positions between the 3 rf output studs 136, cooling grooves 134 are also formed. The cooling recess 134 is a groove structure recessed downward from the surface of the operating head 13, and a plurality of fluid inlets and fluid outlets 135 are uniformly distributed at the bottom of the groove structure. The plurality of fluid inlets and outlets 135 are connected to the inflow and outflow tubes, respectively, of the cooling fluid circuit. A cooling cover (not shown) is sealingly provided on top of the cooling groove 134 and is sealingly engaged with the cooling groove 134 by a sealing member such as a gasket to form a sealed cooling space, so that the cooling fluid is sealed in the cooling space. The sealed space preferably has a Y-shape in plan view. Of course, other forms of graphics, such as a herringbone or other shapes, may be selected.

the cooling cover is made of metal with good heat conduction, and 304 stainless steel is preferably used as the material of the cooling cover in view of the biological safety of the surgical process. The cooling effect of the operating head 13 in the respective region is achieved by cooling fluid in a cooling space below the cooling cover.

The cooling fluid may be a cooling gas or a cooling liquid, and the temperature of the cooling fluid is set to 10 to 15 degrees. If the temperature of the cooling fluid is set too high, it is difficult to achieve the cooling effect, and if the temperature is too low, the cooling of the human tissue is excessive, which may cause the molten fat to be difficult to be discharged from the skin tissue, resulting in a situation in which edema is aggravated.

One or more temperature sensors 133 are disposed in the rf output head 136 and the free area of the cooling space, and the temperature sensors 133 are configured to measure the real-time temperature of the surface of the operating head 13 and the skin in substantial contact with the surface of the operating head 13. Preferably, the number of the temperature sensors 133 is 3. When there is one temperature sensor 133, the measured temperature is the temperature directly measured by the temperature sensor 133; when the sensor is plural, the measured temperature may be an average or a weighted average of direct measurements of the plural temperature sensors 133.

Referring to fig. 4, a control method of the apparatus for removing puffy fat at the eye region is described, as shown in fig. 4, which shows a control manner of one operation cycle, wherein 20-100 operation cycles are often required for completing the operation because the rf fat removal requires sufficient heat energy, and for a more concise illustration of the control method, only the control manner of one operation cycle is shown in fig. 4, and the control manners of the other operation cycles are the same as those in fig. 4. The temperatures appearing hereinafter are all temperature signals collected by the temperature sensor 133 located on the surface of the operating head 13.

S1, at the beginning of the operation (time T0), the operating head 13 of the radio frequency handle 1 is fully contacted with the pouch part, after the temperature is stabilized, the temperature is measured by the temperature sensor 133, and after the operating head 13 is fully contacted with the skin, the temperature of the operating head 13 is the reference temperature, namely the body temperature (T0).

S2, the heating area 131 of the operating head 13 is controlled to heat the skin of the pouch part, and the temperature measured by the temperature sensor 133 of the operating head 13 reaches T1 at time T1, wherein T1 is 110% of T0-120% of T0, and the skin and the adipose tissues of the eyes can be relaxed by heating the pouch part by 10% -20% of the temperature, so that preparation is made for subsequent radio frequency fat elimination.

Preferably, the ramp rate, i.e., (T1-T0)/(T1-T0) is less than 5 degrees Celsius per second and greater than 2 degrees Celsius per second. If the temperature rise rate is too high, the skin capillaries become congested, and capillary bleeding is caused in the radio frequency fat elimination stage, so that the edema is aggravated. If the heating rate is too low, the operation time can be prolonged, and the user experience is reduced.

S3, preserving heat of the eyes, namely stopping heating after the temperature detected by the sensor reaches T1, and preserving heat for time T2. Preferably, 1 minute < t2-t1<3 minutes. The eye skin and tissues can be fully relaxed within the heat preservation time, and heat can be transferred to the fat cells in a deeper layer, thereby being beneficial to subsequent thermal ablation.

S4, at time t2, applying 3 radio frequency signals simultaneously under the heat preservation state of the heating component, wherein the frequency of the radio frequency signals is 40.67 MHz. Due to the application of the radio frequency, the temperature detected by the temperature sensor 133 on the surface of the operating head 13 rises to the temperature T2 in a short period (time period T2-T3), and then enters a temperature stabilization phase after time T3. The T2 is the ablation temperature, which depends on the operation of the rf output head 136 and does not need to be individually preset.

referring to fig. 5, three sets of rf signal output patterns are shown. As shown in fig. 5, the three sets of rf signals have the same frequency, and are all rf square waves of 40.67MHz, but the waveform of output 2 is 1/4 square wave period later than the waveform of output 1; the square wave of output 3 is also 1/4 th of a square wave period later than the square wave of output 2, and the square wave of output 3 is 1/2 th of a square wave period later than the square wave of output 1. Through the application of the plurality of groups of radio frequencies with phase differences, the radio frequency energy is more uniformly distributed in time and space, the uniformity in the fat ablation process is facilitated, and skin depression after operation is avoided.

S5, maintaining the radio frequency output and the heating component in a heat preservation state during the time t2-t4, preferably, t4-t2 is between 1 minute and 3 minutes.

S6, stopping the radio frequency output at time T4, but maintaining the heating component in a heat preservation state, and stopping the radio frequency enables the detection temperature of the temperature sensor 133 on the surface of the operating head 13 at T5 to be reduced to T3, wherein T3 is preferably T3 which is 110% T0-120% T0, and the heat preservation is continued until time T6. Wherein t6-t5 is in the range of 3-5 minutes.

The second section of heat preservation time can make the adipose tissue after the radio frequency ablation fully pass through the skin at higher temperature and discharge, and the condition of edema can further be reduced to the abundant discharge of ablation fat and other tissue fluids.

S7, cooling the eyes through a cooling cover of the operating head 13 at a time T6-T7 to reduce the eye temperature to T4, wherein the T4 is set to be 50% T0-70% T0, and the temperature reduction rate (T3-T4)/(T7-T6) is controlled to be 0.5-1 ℃ per second. If the cooling rate is too great, excessive shrinkage of tissue may occur on the eye under rapid cooling, causing excessive stretching, such that the remaining fat undergoes excessive shrinkage with the excessively stretched tissue, resulting in uneven distribution of fat after surgery. If the temperature drops too slowly, the operation time can be prolonged, and the user experience can be reduced.

S8, at the stage of time T7-T8, the temperature is continuously controlled to be T4 through the cooling plate, the temperature is controlled to be T8-T7 for 2 minutes, and eye tissues can be stabilized through sufficient slow cooling, so that edema is further eliminated.

S9, in the stage of T8-T9, the eye temperature is adjusted back to the original body temperature T0 through the heating component, and therefore a surgical cycle is completed.

The device for removing the swelling fat of the eyes and the control method thereof can enable the fat ablation to be more uniform and can reduce the inflammatory reaction and edema after the operation.
