[0002] A high-frequency treatment head is a medical device that inserts needles into the skin, at least to the depth of the dermis, generating a high-frequency radiofrequency current. This stimulates collagen and elastin synthesis in the dermis below the epidermis, promoting skin regeneration and achieving skin rejuvenation and firming effects. After acupuncture treatment, it is often necessary to apply medication or nutrient solution to promote skin repair. However, post-operative medication application is slow to absorb into the skin. Utility Model Content

[0003] The main purpose of the present utility model is to propose a high-frequency treatment head, a handpiece and a high-frequency treatment device for skin treatment, which are intended to inject liquid medicine into at least the dermis layer for invasive treatment and drug injection treatment at the same time as needle treatment, thereby promoting rapid cell repair.

[0004] To achieve the above-mentioned purpose, the high-frequency treatment head for skin treatment proposed in the present invention includes a shell, a needle assembly and a drug introduction tube. The end face of the shell is provided with multiple through holes. The needle assembly includes multiple needles and a needle plate for fixing the multiple needles. The needle assembly is arranged in the shell. The needles are configured to extend out of the through holes to invade the skin. The needles are electrically connected to the needle plate to apply high-frequency energy to the skin. The drug introduction tube is connected to the multiple through holes. The drug output by the drug introduction tube is output to the skin through the multiple through holes or at least partially output into the skin along the multiple needles.

[0005] In one embodiment, a liquid guide cavity is formed between the end surface and the needle plate, the liquid guide cavity is communicated with the through hole, and the output port of the drug introduction tube is communicated with the liquid guide cavity; the size of each of the through holes is larger than the cross-sectional area of ​​the needle, so that a liquid-excess gap is formed between the side wall of the through hole and the needle, and the drug liquid output by the drug introduction tube passes into the liquid guide cavity and is output from the multiple liquid-excess gaps.

[0006] In one embodiment, the high-frequency treatment head further includes a refrigerant tube, and the end surface is further provided with a refrigerant outlet. The refrigerant tube is connected to the refrigerant outlet, and the refrigerant output by the refrigerant tube is output to the skin surface through the refrigerant outlet.

[0007] In one embodiment, the refrigerant outlet is an annular groove and is disposed around the periphery of all the through holes.

[0008] In one embodiment, the drug introduction tube and / or the refrigerant tube are disposed inside the housing.

[0009] In one embodiment, the drug introduction tube and / or the refrigerant tube are disposed outside the housing and fixed to the housing.

[0011] In one embodiment, the high-frequency treatment head further includes a humidity sensor disposed on the end surface, the drug introduction tube is provided with a first control valve for controlling the opening or closing of the drug introduction tube, and the humidity sensor is directly or indirectly communicated with the first control valve.

[0012] The present invention also proposes a handpiece, which includes the high-frequency treatment head proposed above and a handpiece body, wherein the high-frequency treatment head is detachably connected to the handpiece body, and a high-frequency energy generator and a controller are arranged in the handpiece body, and the controller is directly or indirectly connected to the high-frequency energy generator and the high-frequency treatment head in communication, and the high-frequency energy generator is configured to electrically connect the needle plate and set the multiple needles as electrodes to apply high-frequency energy when invading the skin.

[0013] The present invention also provides a high-frequency treatment device, which includes the handpiece provided above.

[0014] This high-frequency treatment head is equipped with a drug delivery tube for delivering medication. The drug delivery tube is connected to a through-hole in the end face of the housing. During acupuncture treatment, the needle repeatedly extends and retracts relative to the housing of the treatment head. The drug delivered by the drug delivery tube is delivered to the skin surface through the through-hole and flows along the needle into the treatment surface as the needle penetrates. Compared to the existing method of separating acupuncture treatment and skin medication application, because the skin surface is now in the position penetrated by the needle, the drug can quickly flow along the needle into the deeper tissues of the skin, thereby accelerating the absorption of the drug by skin cells and promoting rapid skin repair.

[0025] The present utility model provides a high-frequency treatment head 100 for skin treatment.

[0026] See also Figures 1 to 3 The high-frequency treatment head 100 in this embodiment includes a shell 1, a needle assembly and a drug introduction tube 3. The end surface of the shell 1 is provided with a plurality of through holes 12. The needle assembly includes a plurality of needles 2 and a needle plate 21 for fixing the plurality of needles 2. The needle assembly is arranged in the shell 1. The needles 2 are configured to extend out of the through holes 12 to penetrate the skin. The needles 2 are electrically connected to the needle plate 21 to apply high-frequency energy to the skin. The drug introduction tube 3 is connected to the plurality of through holes 12. The drug output by the drug introduction tube 3 is output to the skin through the plurality of through holes 12 or at least partially output into the skin along the plurality of needles 2.

[0027] It should be noted that the end surface of the housing 1 is the treatment surface that contacts the skin during treatment. Multiple through-holes 12 are formed in the end surface of the housing 1, and each needle 2 within the housing 1 is positioned directly opposite a through-hole 12. Each needle 2 has an initial position retracted within the housing 1 and a treatment position extending out of the through-hole 12. Specifically, the high-frequency treatment head 100 is further provided with a needle drive mechanism (not shown) for driving the needle 2 to perform linear reciprocating motion along the axis of the through-hole 12, thereby switching the needle 2 between the treatment position and the initial position.

[0028] The high-frequency treatment head 100 is used in conjunction with a handpiece body, and a high-frequency energy generator and a controller are provided in the handpiece body. When in use, the high-frequency treatment head 100 is connected to the handpiece body, and the controller is electrically connected to the high-frequency energy generator and the high-frequency treatment head 100. The high-frequency energy generator is configured to be electrically connected to the needle plate 21 and to set the multiple needles 2 as electrodes to apply high-frequency energy when invading the skin. This high-frequency energy can be radio frequency energy with a frequency in the range of 1 MHz to 20 MHz.

[0029] The specific operating steps of needle therapy are as follows: the treatment surface of the high-frequency treatment head 100 is placed in contact with the skin. The needle drive mechanism then drives the needle 2 out of the through hole 12 to penetrate the skin. The needle 2 is then controlled to discharge and generate a heat diffusion zone under the skin. During this process, the drug output by the drug inlet tube 3 can be output to the skin surface through the through hole 12 and flow along the needle 2 into the interior of the treatment surface as the needle 2 penetrates. Compared to the existing method of separating needle therapy and skin drug application, because the skin surface is now in the position penetrated by the needle 2, the drug can quickly flow along the needle 2 into the deep tissue of the skin, thereby accelerating the absorption of the drug by skin cells and promoting rapid skin repair.

[0030] It should be noted that in order to reduce the pain when the needle 2 pierces the skin, the needle 2 is usually very thin, so the needle 2 is easily bent under the action of external force. Figure 2 In the embodiment shown, guide ribs 15 are provided at the through hole 12 and are spaced apart on the inner peripheral wall of the through hole 12. The guide ribs 15 can provide lateral support for the needle 2 in different directions, thereby preventing the needle 2 from bending.

[0031] In one embodiment, a liquid guiding cavity 11 is formed between the end face of the housing 1 and the needle plate 21. The liquid guiding cavity 11 is connected to the through-hole 12. The output port of the drug introduction tube 3 is connected to the liquid guiding cavity 11. At this time, the size of each through-hole 12 is larger than the cross-sectional area of ​​the needle 2, so that a liquid gap is formed between the side wall of the through-hole 12 and the needle 2. At this time, the drug liquid output by the drug introduction tube 3 enters the liquid guiding cavity 11 and is output from the multiple liquid gaps on the end face.

[0032] In this embodiment, the output port of the drug introduction tube 3 is connected to the liquid guide cavity 11, and further connected to the through hole 12, so that the drug liquid output by the drug introduction tube 3 first fills the liquid guide cavity 11, and then is output to the skin through the multiple liquid-passing gaps distributed on the end surface between each through hole 12 and the needle 2, so that the drug liquid can be output to the skin more evenly.

[0033] As is readily understood, during acupuncture treatment, high-frequency energy can cause skin temperature to rise, resulting in a burning sensation. To cool the skin, the high-frequency treatment head 100 also includes a refrigerant tube 4. The end surface of the housing 1 is also provided with a refrigerant outlet 14. The refrigerant tube 4 is connected to the refrigerant outlet 14, and the refrigerant outputted by the refrigerant tube 4 is delivered to the skin surface via the refrigerant outlet 14. By providing the drug inlet tube 3 and the refrigerant tube 4, the high-frequency treatment head 100 can simultaneously deliver medication and cool the skin during acupuncture treatment, achieving simultaneous treatment, repair, and soothing effects.

[0034] The refrigerant outlet 14 is an annular groove and is arranged around the periphery of all the through holes 12. That is, the refrigerant outlet 14 is arranged around the edge of the treatment surface, forming a cooling ring at the edge of the treatment surface.

[0035] Among them, the drug introduction tube 3 and / or the refrigerant tube 4 can be arranged inside the shell 1, that is, the input port of the drug introduction tube 3 and / or the refrigerant tube 4 can be arranged inside the shell 1. With such a highly integrated design, the structure of the high-frequency treatment head 100 is more compact; alternatively, the drug introduction tube 3 and / or the refrigerant tube 4 are arranged outside the shell 1 and partially fixed to the shell 1, and their output ports extend to the liquid guide cavity 11 to communicate with the liquid guide cavity 11. When the input port of the drug introduction tube 3 is arranged outside the shell 1, it is convenient for the drug introduction tube 3 to be connected to the medicine tank. When the input port of the refrigerant tube 4 is arranged outside the shell 1, it is convenient for the refrigerant tube 4 to be connected to the refrigerant tank. The refrigerant stored in the refrigerant tank can be hydrogen, nitrogen or helium, etc. The refrigerant tank can be a high-pressure liquid tank. The refrigerant tank is controlled to open and close by the second control valve on the refrigerant tube 4. The second control valve can be a solenoid valve, a butterfly valve, etc. During the acupuncture treatment, the liquid high-pressure refrigerant enters the refrigerant tube 4 and is ejected through the refrigerant outlet 14 to act on the treated skin, thereby quickly cooling the skin.

[0036] The second control valve can be controlled manually or electrically.

[0037] In one embodiment, the high-frequency treatment head 100 further includes a temperature sensor (not shown) configured to communicate directly or indirectly with the second control valve. The temperature sensor is positioned on the treatment surface and is used to detect the temperature of the treated skin. The operator can obtain the current temperature of the treated skin through the temperature sensor. When the real-time temperature reported by the temperature sensor reaches a first preset temperature, indicating that the skin temperature is high and requires cooling, the operator is instructed to control the second control valve to open, thereby delivering refrigerant to the treated skin for cooling. When the real-time temperature reported by the temperature sensor is lower than the second preset temperature, indicating that the skin temperature is low and no further cooling is required, the operator is instructed to control the second control valve to close, thereby stopping the delivery of refrigerant.

[0038] Alternatively, a controller within the handpiece body is electrically connected to the temperature sensor and the second control valve. When the real-time temperature reported by the temperature sensor reaches a first preset temperature, the controller controls the second control valve to open, thereby allowing refrigerant to flow through the refrigerant pipe 4. When the real-time temperature reported by the temperature sensor falls below a second preset temperature, the controller controls the second control valve to close, thereby closing the refrigerant pipe 4 and stopping the flow of refrigerant.

[0039] In this embodiment, the controller is electrically connected to the temperature sensor and the second control valve. The controller automatically controls the opening and closing of the second control valve according to the signal fed back by the temperature sensor. This not only reduces the need for manual operation, but also responds quickly and avoids the lag of manual operation.

[0040] In the high-frequency treatment head 100, the drug introduction tube 3 is provided with a first control valve (not shown), such as a solenoid valve or a butterfly valve, for controlling the opening and closing of the drug introduction tube 3. The first control valve can be controlled manually or electrically.

[0041] In one embodiment, the high-frequency treatment head 100 further includes a humidity sensor (not shown) configured to communicate directly or indirectly with the first control valve. The humidity sensor is positioned on the treatment surface and is used to detect the humidity of the skin being treated. The operator can use the humidity sensor to determine the humidity location of the treated skin. When the real-time humidity reported by the humidity sensor is lower than a first preset humidity, it indicates that the skin is relatively dry, thereby instructing the operator to control the first control valve to open. When the real-time humidity reported by the humidity sensor reaches a second preset humidity, it indicates that the skin cells are saturated with water and can no longer absorb the liquid medicine. Therefore, the operator is instructed to control the first control valve to close, halting the delivery of the liquid medicine and preventing repeated delivery of the liquid medicine to the same treatment location.

[0042] The high-frequency treatment head 100 is designed to be removably connected to the handpiece body, such as by a threaded or snap-fit ​​connection. The handpiece body serves as a grip for the operator. A controller is housed within the handpiece body and is electrically and communicatively connected to the humidity sensor and the first control valve. When the real-time humidity reported by the humidity sensor falls below a first preset humidity, the controller controls the first control valve to open, thereby allowing drug delivery through the drug inlet tube 3. When the real-time humidity reported by the humidity sensor reaches a second preset humidity, the controller controls the first control valve to close, thereby closing the drug inlet tube 3 and halting drug delivery.

[0043] In this embodiment, the controller is electrically and communicatively connected to the humidity sensor and the first control valve. The controller automatically controls the opening and closing of the first control valve according to the signal fed back by the humidity sensor. This not only reduces the need for manual operation but also provides a fast response and avoids the lag of manual operation.

[0044] The present invention also provides a handpiece, which includes a high-frequency treatment head 100 and a handpiece body. The specific structure of the high-frequency treatment head 100 is similar to the above-mentioned embodiments. Since the present handpiece adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, which will not be described in detail here. The high-frequency treatment head 100 is detachably connected to the handpiece body. A high-frequency energy generator and a controller are disposed within the handpiece body. The controller is directly or indirectly connected to the high-frequency energy generator and the high-frequency treatment head 100. The high-frequency energy generator is configured to electrically connect to the needle plate 21 and configure the plurality of needles 2 as electrodes to apply high-frequency energy when penetrating the skin.

[0045] The present invention further provides a high-frequency treatment device, which includes the handpiece provided above. The beneficial effects of the high-frequency treatment device are described in detail in the above embodiments and will not be described in detail here.
