[0002] RF treatment heads apply an RF electric field to the skin through electrodes placed against the skin. The field's passage through the skin creates a thermal effect, which has a therapeutic effect. RF energy heats the skin. Too little heat can weaken the treatment, while too much heat can cause burns. Therefore, RF treatment heads typically require a temperature sensor to monitor skin temperature in real time.

This allows the skin temperature to be transmitted to the sensor via the electrode, enabling real-time temperature monitoring. However, this edge-mounted fixation can cause warping in the center of the sensor, creating an air gap between the sensor and the electrode, which can affect temperature measurement accuracy.

[0030] The utility model provides a radio frequency treatment head.

[0031] See also Figures 1 to 5 An embodiment of the radio frequency treatment head includes a shell 1, an electrode 2, a temperature measuring module 3 and an elastic member 4. An opening is opened at one end of the shell 1, and the electrode 2 is arranged in the opening. The temperature measuring module 3 is arranged in the shell 1 and is fitted with the electrode 2. The elastic member 4 is arranged on the side of the temperature measuring module 3 away from the electrode 2, and is used to press the temperature measuring module 3 so that the temperature measuring module 3 and the electrode 2 are tightly fitted.

[0032] The electrode 2 on this radiofrequency treatment head is made of a metal material with good electrical and thermal conductivity, such as copper and steel. During use, the electrode 2 adheres to the skin and transmits radiofrequency energy to the skin. Radiofrequency energy can cause the skin temperature to rise. To ensure that the skin temperature is always within the appropriate temperature range during treatment, a temperature measurement module 3 is required to monitor the skin temperature in real time. The radiofrequency treatment head is equipped with an radiofrequency energy transmitter and a control circuit board. The control circuit board is electrically connected to the radiofrequency energy transmitter and the temperature measurement module 3. The control circuit board controls the radiofrequency energy transmitter to transmit energy based on the real-time temperature feedback from the temperature measurement module 3.

[0033] In order to achieve the installation and fixation of the temperature measuring module 3, traditional radio frequency treatment heads usually fix the edge of the temperature measuring module 3 to the shell 1 by snapping it together. However, the edge fixing method may cause the central part of the temperature measuring module 3 to warp, that is, there is an air gap between the temperature measuring module 3 and the electrode 2, thereby affecting the accuracy of temperature measurement. Unlike traditional radio frequency treatment heads, the radio frequency treatment head of the present invention is provided with an elastic member 4, such as a spring, a rubber pad and a bellows, on the side of the temperature measuring module 3 facing away from the electrode 2, so as to provide continuous pressure to the temperature measuring module 3 with the help of the elastic force of the elastic member 4, thereby ensuring that the temperature measuring module 3 is always tightly fitted with the electrode 2, thereby eliminating the air gap between the temperature measuring module 3 and the electrode 2, so that the temperature measuring module 3 can more accurately sense the temperature of the skin.

[0034] The temperature measurement module 3 of a conventional radiofrequency therapy head consists of thermally conductive silicone rubber and a temperature measuring element 32. The thermally conductive silicone rubber is positioned within the housing 1 and in contact with the electrode 2. The temperature measuring element 32 is mounted on the thermally conductive silicone rubber. This allows skin temperature to be transmitted to the electrode 2 and then, via the thermally conductive silicone rubber, to the temperature measuring element 32, thus enabling real-time monitoring of skin temperature. However, due to the thickness and low thermal conductivity of the thermally conductive silicone rubber, there can be a certain deviation and delay between the temperature detected by the temperature measuring element 32 and the actual skin temperature.

[0035] In some embodiments of the present invention, the temperature measurement module 3 includes a metal thermally conductive sheet 31 and a temperature measuring element 32. The metal thermally conductive sheet 31 is disposed within the housing 1 and is in contact with the electrode 2. An insulating thermally conductive film 311 is provided on the side of the metal thermally conductive sheet 31 that contacts the electrode 2. The temperature measuring element 32 is disposed on the side of the metal thermally conductive sheet 31 that faces away from the electrode 2. In this case, an elastic member 4 is disposed on the side of the metal thermally conductive sheet 31 that faces away from the electrode 2 and is used to press the metal thermally conductive sheet 31 to ensure a tight contact with the electrode 2.

[0036] This embodiment eliminates the thermally conductive silicone rubber and instead utilizes a metal thermally conductive sheet 31 to facilitate heat transfer between the electrode 2 and the temperature measuring element 32. Specifically, this radiofrequency treatment device has a thin metal thermally conductive sheet 31 attached to the side of the electrode 2 facing away from the skin. The sheet 31 is compressible to approximately 0.1 mm thick, and the temperature measuring element 32 is positioned on the side of the sheet 31 facing away from the electrode 2. To prevent short circuits between the temperature measuring element 32 and the electrode 2, an insulating thermally conductive film 311, such as PI film or PET film, is applied to the side of the sheet 31 that contacts the electrode 2. In this technical solution, the overall thickness of the metal thermal conductive sheet 31 and the insulating thermal conductive film 311 can be made thinner than the thickness of the thermally conductive silicone, thereby reducing the distance of heat transfer between the surface skin and the temperature measuring element 32, and the thermal conductivity of the metal thermal conductive sheet 31 is also higher than that of the thermally conductive silicone, thereby being able to transfer heat from the electrode 2 to the temperature measuring element 32 more quickly, thereby reducing the deviation between the temperature detected by the temperature measuring element 32 and the actual temperature of the skin, and improving the accuracy of temperature detection.

[0037] The metal heat conducting sheet 31 is connected to a flexible circuit board 312 , and the flexible circuit board 312 is used to connect the temperature measuring element 32 and the control circuit board, thereby achieving electrical connection between the temperature measuring element 32 and the control circuit board.

[0038] In one embodiment, the elastic member 4 is a rubber pad having a bearing surface for contact with the metal thermally conductive sheet 31. The bearing surface covers an area no less than that of the metal thermally conductive sheet 31, thereby ensuring that every area of ​​the metal thermally conductive sheet 31 is firmly pressed against the electrode 2. In this case, a recessed groove is provided on the bearing surface, and the temperature measuring element 32 is embedded in the groove. The groove not only provides a stable mounting position for the temperature measuring element 32, but also ensures that when the rubber pad is in contact with the metal thermally conductive sheet 31, the presence of the temperature measuring element 32 prevents local bulging.

[0039] Reference Figure 3 In order to achieve the installation of the rubber pad, a partition 11 is provided in the chamber of the shell 1. The partition 11 is spaced apart from the electrode 2. The distance between the partition 11 and the electrode 2 is less than the thickness of the rubber pad. The rubber pad is arranged between the metal thermal conductive sheet 31 and the partition 11 in an extruded state. The rubber pad is arranged between the metal thermal conductive sheet 31 and the partition 11 in a compressed state, which can ensure that the rubber pad can provide a continuous and uniform elastic extrusion force to the metal thermal conductive sheet 31, thereby ensuring that the metal thermal conductive sheet 31 is always in close contact with the electrode 2. It should be noted that the thickness of the above-mentioned rubber pad refers to the thickness of the rubber pad in its natural state without being squeezed or stretched by external force. In some embodiments, the elastic member 4 can also be a spring, and the length of the spring in its natural state is greater than the distance between the partition 11 and the electrode 2.

[0040] Reference Figure 6In some embodiments of the present invention, a temperature measuring area 21 is provided on the side of the electrode 2 facing the metal heat conductive plate 31, a first heat resistance groove 22 is provided around the temperature measuring area 21, and the temperature measuring element 32 is arranged opposite to the temperature measuring area 21.

[0041] Specifically, a first heat-resistance groove 22 is recessed on the side of the electrode 2 facing the metal heat-conducting plate 31. The first heat-resistance groove 22 is arranged in an annular shape, and the area enclosed by the first heat-resistance groove 22 forms the temperature measurement area 21. The temperature measuring element 32 is arranged directly opposite the temperature measurement area 21. The provision of the first heat-resistance groove 22 prevents heat from the temperature measurement area 21 from easily dissipating and diffusing to the surrounding area, ensuring that the heat of the electrode 2 is primarily concentrated in the temperature measurement area 21. This allows the temperature measuring element 32 to more accurately measure the actual temperature of the area in contact between the electrode 2 and the skin, reducing the impact of heat loss on the measurement results and enhancing the speed and accuracy of temperature measurement.

[0042] Furthermore, at least two first heat-resistant grooves 22 are provided, and at least two first heat-resistant grooves 22 are arranged concentrically. In this case, the area enclosed by the innermost circle of first heat-resistant grooves 22 constitutes the temperature measurement area 21. Providing multiple first heat-resistant grooves 22 further prevents the temperature of the temperature measurement area 21 from spreading to the surrounding area, making the temperature measured by the temperature measuring element 32 closer to the actual skin temperature.

[0043] In some embodiments, at least two temperature measurement zones 21 are provided. These two or more temperature measurement zones 21 are spaced apart on the side of the electrode 2 facing the metal heat conductive plate 31, and each temperature measurement zone is surrounded by a first heat-resistance groove 22. In this case, the number of temperature measurement elements 32 matches the number of temperature measurement zones 21, with one temperature measurement element 32 positioned opposite one temperature measurement zone 21, and each temperature measurement element 32 is used to detect the temperature of one temperature measurement zone 21.

[0044] The setting of multiple temperature measurement zones 21 allows temperature monitoring of different areas of the electrode 2, thereby providing more comprehensive thermal feedback, so as to promptly detect situations where the local temperature of the treated skin is too high or too low, or promptly detect situations where the metal thermal conductive plate 31 is partially warped and the temperature on one side is too high.

[0045] At this time, a second heat-resisting groove 23 is provided between adjacent temperature measurement zones 21 , and the length direction of the second heat-resisting groove 23 is provided at an angle to the direction of the line connecting the center points of the two temperature measurement zones 21 .

[0046] Specifically, the second heat-resistance groove 23 is a strip-shaped groove, with its length direction angled with the direction of the line connecting the center points of the temperature measurement zones 21. The angle between the two can be 30°, 45°, 90°, etc., without limitation. The provision of the second heat-resistance groove 23 prevents the temperature of one temperature measurement zone 21 from spreading to another, thereby ensuring that the temperature of each temperature measurement zone 21 is more independent and accurate.

[0047] The present invention further provides a radiofrequency treatment handle 100 , comprising a fixed shell 5 and any one of the radiofrequency treatment heads provided above, wherein the fixed shell 5 is covered with an end of the housing 1 away from the electrode 2 to form an integral structure.

[0048] In this embodiment, the radiofrequency treatment head and the fixed shell 5 together constitute the radiofrequency treatment handle 100. The two are covered to form an integrated structure, which prevents the electronic components inside the radiofrequency treatment head from being exposed to the outside, thereby improving the safety and service life of the radiofrequency treatment head. Since the outer electrode 2 of the radiofrequency treatment head needs to contact the skin during treatment, in order to meet the different uses of multiple people and avoid one component contacting the skin of multiple people, the radiofrequency treatment head will often need to be replaced. The fixed shell 5 and the housing 1 are connected in a convenient detachable manner, making it easy for users to replace the radiofrequency treatment head. In one embodiment, a slot 12 is provided on the housing 1, and a hook 51 is provided on the fixed shell 5. The hook 51 can be extended into the slot 12 to fix the hook 51 in the slot 12; the hook 12 has a bevel. When the position of the hook 51 on the fixed shell 5 is pressed, the hook 51 can be disengaged from the slot 12, so that the radiofrequency treatment head can be removed from the fixed shell 5 for easy replacement with another radiofrequency treatment head. The fixed shell 5 and the housing 1 can also be connected in other detachable ways, such as a magnetic structure.

[0049] The present invention also provides a radiofrequency therapeutic device, comprising a main unit and a radiofrequency therapeutic handle 100. The specific structure of the radiofrequency therapeutic handle 100 is similar to that of the aforementioned embodiments. Since the present radiofrequency therapeutic device utilizes all of the technical solutions of all of the aforementioned embodiments, it possesses at least all of the beneficial effects provided by the technical solutions of the aforementioned embodiments, which will not be further detailed here. The radiofrequency therapeutic handle 100 is connected to the main unit (not shown) via a wiring harness 6. In one embodiment, the fixed housing 5 has a wiring harness hole, through which the wiring harness 6 passes and connects to the control circuit board on the radiofrequency therapeutic handle.

[0050] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
