[0001] This application relates to the field of medical device technology, and in particular to array electroacupuncture structures and medical aesthetic devices. Background Technology

[0002] Radiofrequency microneedling is a commonly used medical aesthetic device that delivers radiofrequency energy to specific tissue areas via microneedles. The therapeutic effect of radiofrequency microneedling directly depends on the uniformity of radiofrequency energy application within the system, which is closely related to the electrode arrangement and excitation design.

[0003] Existing radio frequency microneedles are generally arranged in a rectangular pattern. During energy transfer, the energy of microneedles at the boundaries will always be less than that of microneedles at the center. At the same time, the rectangular design also results in a larger proportion of boundary microneedles, further affecting energy transfer. Moreover, whether the boundary microneedles are located on the side or at the corner has a significant impact on energy distribution, leading to severely uneven energy distribution.

[0027] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0028] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0029] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0030] Radiofrequency microneedling is a commonly used invasive aesthetic medical device that delivers radiofrequency energy to specific tissue areas via microneedles. It is typically divided into monopolar or bipolar microneedle systems. Monopolar microneedles use all arrayed microneedles as the positive electrode, with a neutral electrode forming the circuit loop; bipolar microneedles use pairs of microneedles as positive and negative electrodes in the microneedle array to form a radiofrequency current loop. The therapeutic effect of a microneedle system directly depends on the uniformity of the radiofrequency energy applied within the system, which is closely related to the electrode arrangement and excitation design.

[0031] Specifically, the working principle of a monopolar radiofrequency microneedling system is relatively simple. In this system, all microneedles are designed as positive electrodes, while a neutral electrode placed at the working point serves as the negative electrode, forming a complete circuit. When radiofrequency energy is delivered to the skin tissue through the microneedles, it generates heat within the tissue. This heat stimulates collagen contraction and regeneration, thereby achieving a firming and lifting effect.

[0032] Understandably, the advantage of monopolar systems lies in the breadth and depth of their energy delivery. Because the neutral electrode is relatively far from the microneedles, radiofrequency energy can be delivered over a wider area and penetrate deeper into the skin. However, this can also lead to uneven energy distribution, as areas of skin farther from the microneedles may receive less energy.

[0033] Specifically, the bipolar radiofrequency microneedle system employs a more refined energy delivery method. In this system, each pair of microneedles in the microneedle array is designed as positive and negative electrodes, forming multiple small radiofrequency current loops. This design allows energy to be delivered to the skin tissue more concentratedly, while reducing energy loss and unnecessary thermal damage.

[0034] Understandably, the advantage of bipolar systems lies in the precision and uniformity of their energy delivery. Because each micro-target forms an independent circuit, energy can be distributed more evenly within the skin tissue. Furthermore, due to the smaller circuit size, the energy delivery depth is relatively shallow, which helps reduce potential damage to deeper skin structures.

[0035] In summary, the uniformity of radiofrequency energy application is one of the key factors determining the effectiveness of radiofrequency microneedling treatment. Uneven energy distribution will negatively impact the treatment outcome. Specifically, areas with excessively high energy may suffer from excessive heat damage to the skin, while areas with insufficient energy may fail to achieve the desired tightening effect.

[0036] Existing microneedle systems generally use rectangles. In rectangular arrays, due to the geometry of the microneedles and the current flow path, microneedles located at the edges and corners of bipolar systems tend to receive lower current densities than those located at the center. This is because current tends to flow along the shortest path with the least resistance, and in rectangular arrays, these paths are often concentrated in the central part of the array. In unipolar systems, however, energy is excessively concentrated at the corners of the rectangle, resulting in an edge effect.

[0037] Understandably, for example, a 4×6 rectangular microneedle contains a total of 24 microneedles. Please refer to... Figure 1 , Figure 1 This diagram shows the temperature distribution of each needle in the bipolar mode of an existing array electroacupuncture structure. At 0.1 seconds of excitation, due to the extremely uneven current density distribution, the heating effect received by the 16 needles at the perimeter (i.e., the needles at the edges and corners) is far weaker than that received by the 8 needles at the center. It can be seen that the temperature of the needles at the boundaries is lower than that at the center. The proportion of the 16 needles is 16 / 24 = 2 / 3. That is, 2 / 3 of the microneedles do not achieve the optimal therapeutic effect.

[0038] Based on this, this application proposes an array of electrocautery needles to address the technical problem of poor energy utilization in existing radio frequency microneedles. Please refer to... Figure 2 , Figure 2 This is a schematic diagram of an embodiment of the array electrocautery structure of this application.

[0039] In this embodiment, the array of electrocautery needles includes: a plurality of electrocautery needle units 10; each electrocautery needle unit 10 is a regular hexagonal structure composed of six electrocautery needles.

[0040] It should be noted that the electroacupuncture needles are carriers that receive electrical excitation. In the array electroacupuncture needle structure, each needle is connected to an excitation source and receives excitation from the source. These currents create an electric field between the needles, thereby acting on the treatment area.

[0041] Specifically, the electrocautery unit 10 is used to receive current-excited output energy. The electrocautery unit 10 is connected to the radio frequency power supply via a specific connection method, such as a wire. When the radio frequency power supply is turned on, current flows through the electrocautery unit along a predetermined path, thereby exciting it.

[0042] Understandably, upon receiving electrical stimulation, the electroacupuncture unit 10 converts it into heat or other forms of energy and outputs it to the surrounding tissue. This energy output is the core mechanism of radiofrequency microneedling treatment, which can stimulate collagen regeneration and remodeling in skin tissue, thereby achieving the effects of tightening the skin, reducing wrinkles, and improving skin texture.

[0043] Understandably, the hexagonal structure composed of six electric needles forms a hollow hexagonal structure. This design not only maintains the stability of the structure, but also allows each electric needle to form a good current loop with the adjacent electric needles, which helps to distribute the current evenly.

[0044] Understandably, the hollow hexagonal structure means that the electrodes are not directly connected to the center, but rather the connections are established through the vertices of the hexagon. This design helps reduce direct interference between the electrodes while maintaining smooth current transmission.

[0045] Furthermore, each of the described electroneedle units 10 is radiating outward from the inside with one electroneedle unit 10 as the center and connected by a connection method that shares the side composed of adjacent electroneedles to form a splice body; any electroneedle on the inner side of the splice body boundary is surrounded by three electroneedles.

[0046] It should be noted that the splicing body refers to the compact structure formed by the shared connection method described above for each of the aforementioned needle units 10. Its compactness depends only on the side length of the regular hexagonal structure, and the optimal side length of the regular hexagonal structure can be determined experimentally. The boundary of the splicing body consists of needles on the outer side of the entire array needle structure that are not shared with other needle units.

[0047] Understandably, during the splicing process, each needle unit 10 shares one or more edges with its adjacent needle units 10, thus forming a tightly connected network structure. This structure not only enhances the stability of the entire splice but also facilitates the smooth transmission of current.

[0048] It is understandable that, since the splice body boundary electric needles do not share electric needles with other electric needle units 10, it is impossible for any electric needle to be surrounded by three electric needles.

[0049] Understandably, within the boundaries of the assembly, any needle is surrounded by at least three other needles. Specifically, since each needle unit is a regular hexagonal structure, inside the assembly, each needle is adjacent to needles from three adjacent needle units.

[0050] Understandably, this configuration ensures that even the electrode needles located at the edges receive sufficient current excitation, thus avoiding the problem of weak heating of edge electrode needles in existing rectangular arrays. At the same time, it also makes the current distribution more uniform throughout the entire assembly.

[0051] In particular, the arrangement scheme of this application can achieve a consistent distribution of the electric needles at the edges, unlike the further uneven distribution caused by differences in the long sides, short sides, and corner points of a rectangular array. Therefore, whether implementing the unipolar excitation or bipolar excitation method described above, energy transfer can be more uniform.

[0052] Specifically, such as Figure 2 As shown, the 24 identical electrocautery needles are arranged in an array of 7 needle units as described above. Please refer to [reference needed]. Figure 3 , Figure 3 The temperature distribution diagram of each electroacupuncture needle in the embodiment of the array electroacupuncture structure of this application shows that, at 0.1s of excitation, the temperature of the boundary electroacupuncture needles is lower than that of the center electroacupuncture needles, and only 1 / 2 of the electroacupuncture needles do not achieve the optimal treatment effect. Moreover, the 12 peripheral electroacupuncture needles are consistent with all other needles, with no differences in "corners" and "edges", which makes the treatment effect of these 12 electroacupuncture needles consistent and has good edge uniformity.

[0053] In this embodiment, an array of hollow hexagonal needle units is used. The structure, where one needle is surrounded by three others, effectively utilizes space while preventing excessive heat accumulation, ensuring uniform heat conduction. Furthermore, the array of multiple needle units achieves a consistent geometric distribution of the needles at the edges, while reducing the proportion of boundary microneedles, significantly improving energy transfer efficiency.

[0054] Furthermore, this application provides an implementation method for stimulating the array of electric needles described above. For example... Figure 4 As shown, Figure 4 This is a structural block diagram of one embodiment of the array electrocautery structure provided in this application.

[0055] The array of electro-needle structures further includes an excitation module 20; the excitation module 20 is connected to the electro-needles of each of the electro-needle units 10; the excitation module 20 is used to excite the electro-needles with current.

[0056] Understandably, the excitation module is responsible for providing electrical excitation to the electroacupuncture needles. It forms one or more current loops by connecting the electroacupuncture needles to each electroacupuncture needle unit. At the same time, the excitation module can precisely control the electroacupuncture needles according to preset parameters (such as current intensity, frequency, waveform, etc.) to achieve specific therapeutic effects.

[0057] It should be noted that implementing the excitation module in an array of electrocautery needles is a complex and delicate process, involving multiple aspects such as current generation, control, and distribution. This typically includes the use of power management circuits and current source circuits. A suitable current source or current regulator is selected based on the required current range and accuracy. The excitation module needs to be connected to the electrocautery needle units, usually via wires or copper traces on a circuit board. The wiring must consider factors such as current distribution, thermal effects, and electromagnetic interference to ensure that the current is delivered evenly and stably to each needle.

[0058] Specifically, an radio frequency (RF) power supply is selected as the core component of the excitation module to generate high-frequency alternating current. The RF current is transmitted to the electrocautery unit via a coaxial cable or a specific connector. The electrocautery needles in the unit vibrate or produce other forms of physical effects based on the characteristics of the RF current, thereby stimulating the surrounding tissue.

[0059] Specifically, a low-to-medium frequency power supply is selected as the core component of the excitation module to generate low-to-medium frequency alternating current or pulsed current. The current is transmitted to the electroacupuncture unit through wires or copper traces on a circuit board. The electroacupuncture unit stimulates the surrounding tissue based on the characteristics of the high-frequency current, such as generating changes in current density and electric field distribution.

[0060] In one feasible implementation, this application provides a bipolar excitation scheme, such as... Figure 5 As shown, Figure 5 This diagram illustrates a first circuit connection method for one embodiment of the array needle structure provided in this application. The excitation module 20 configures each needle unit 10 as a hexagonal structure with three positive needles and three negative needles arranged alternately with positive and negative poles. The first circuit connection method involves each positive needle being connected to the positive terminal of the excitation module 20, and each negative needle being connected to the negative terminal of the excitation module 20.

[0061] It should be noted that the array needle structure consists of three positive needles and three negative needles, arranged in an alternating pattern to form a regular hexagonal structure. This layout ensures that each needle is surrounded by three needles of opposite polarity.

[0062] Understandably, all positive electrode needles are connected to the positive terminal of the excitation module 20, and all negative electrode needles are connected to the negative terminal of the excitation module 20. This connection method simplifies the circuit structure and enables the excitation module to excite all electrode needles simultaneously and uniformly.

[0063] It is understandable that the above method can achieve bipolar excitation of the array of electroacupuncture needles. At the same time, any electroacupuncture needle within the boundary is surrounded by three electroacupuncture needles of opposite polarity. Only one RF power supply can excite once to achieve a uniform treatment effect.

[0064] In one feasible implementation, this application provides a unipolar excitation scheme, such as... Figure 6 As shown, Figure 6This diagram illustrates a second circuit connection method for one embodiment of the array needle structure provided in this application. The excitation module 20 further configures each needle unit 10 as a regular hexagonal structure composed of six positive needles via the second circuit connection method. The array needle structure also includes a neutral electrode plate 11. The second circuit connection method involves each positive needle being connected to the positive terminal of the excitation module 20, and the neutral electrode plate 11 being connected to the negative terminal of the excitation module 20.

[0065] It should be noted that, in addition to the six positive electrode needles, the array needle structure also includes a neutral electrode plate 11. The neutral electrode plate 11 is typically used to provide a return path during electrical stimulation therapy, ensuring that the current can flow safely and effectively through the treatment area.

[0066] In this embodiment, the second circuit connection is characterized by each positive electrode needle being directly connected to the positive terminal of the excitation module 20. Simultaneously, the neutral electrode plate 11 is connected to the negative terminal of the excitation module 20. This connection method ensures that current flows evenly through each positive electrode needle and returns to the excitation module via the neutral electrode plate, forming a complete circuit.

[0067] Understandably, when the excitation module 20 is activated, unipolar excitation can be performed, providing electrical energy to the positive electrode needle. This electrical energy generates an electric field within the treatment area. Due to the effect of the electric field, the cells or tissues within the treatment area are stimulated, thereby achieving the therapeutic purpose and realizing precise stimulation of the treatment area. Simultaneously, the use of a neutral electrode plate ensures the safety and effectiveness of the treatment process.

[0068] Furthermore, to optimize the unipolar excitation effect, the electric needles can be grouped on this structure. In one feasible implementation, such as... Figure 7 As shown, Figure 7 This diagram illustrates a third circuit connection method for one embodiment of the array needle structure provided in this application. The excitation module 20 further groups the needles using this third circuit connection method, generating multiple groups containing the needles.

[0069] Understandably, the number of groups and the number of needles in each group can be determined based on treatment needs and the overall design of the array of electroacupuncture needles. These groups may be arranged in a ring, fan shape, or other geometric shape around the assembly.

[0070] Specifically, this embodiment provides a grouping method that requires that the distance between the electric needles in any group and the center of the splice body is the same, and the distance between adjacent electric needles in any group is the same.

[0071] Understandably, the electroacupuncture needles are divided into multiple groups, with each group having needles at the same distance from the axis of the assembly, and adjacent needles within any group also being equidistant. This grouping method ensures that the needles within each group are in the same working environment, and applying different excitations with different working characteristics to different groups helps to achieve a more uniform electric field distribution and more precise stimulation control.

[0072] It is understood that being in the same working environment means that when the electric needles are divided into multiple groups, and the distance between the electric needles in each group and the center of the assembly is the same, the electric field environment of each group is similar. Furthermore, if the distance between adjacent electric needles in any group is also the same, then the distribution of the electric field among these electric needles will be more uniform.

[0073] In addition, a neutral electrode plate 11 is also required to achieve unipolar excitation, so the array needle structure also includes a neutral electrode plate 11.

[0074] Based on the above, the connection method of the third circuit can be determined, namely, the electric needles of each group are respectively connected to the positive terminal of the excitation module 20; the neutral electrode plate 11 is connected to the negative terminal of the excitation module 20.

[0075] Understandably, since each group of electroacupuncture needles can independently receive electrical energy, the groups can be stimulated sequentially at different times so that the needles in the same group receive stimulation simultaneously. This method effectively controls the transmission of current between the needles, preventing interference between different groups. Furthermore, because the needles in the same group receive stimulation simultaneously, they can form a more stable and uniform electric field, thereby enhancing the therapeutic effect.

[0076] Furthermore, the time-segmented stimulation strategy can be flexibly adjusted according to the patient's specific condition and treatment needs. For example, we can set different stimulation times and current intensities based on factors such as the size and depth of the lesion and the patient's tolerance, to achieve more personalized and precise treatment and help meet more complex treatment needs.

[0077] It should be noted that, taking the array microneedle structure composed of 24 electrocautery needles as an example, the electrocautery needles are divided into four groups as described above: Group A, Group B, Group C, and Group D. Each group contains six electrocautery needles, and the groups can be excited with different working characteristics at different times, provided that any electrocautery needle within a group is at the same distance from the center of the assembly and the distance between adjacent electrocautery needles within the group is also the same. In this case, the excitation module needs to have multi-channel output capability, and each channel needs to be able to independently control its excitation parameters. It also needs to have time-division control functionality to ensure that appropriate excitation is applied to each group of electrocautery needles at different time periods.

[0078] Furthermore, in order to realize the above-mentioned function of time-sharing excitation with different working characteristics, a module for adjusting the excitation module can be introduced to simultaneously realize the switching between unipolar and bipolar excitation. Therefore, the array needle structure may also include: a selection module 30.

[0079] It should be noted that the selection module is connected to the excitation module 20; the selection module is used to receive user requirements and generate a selection signal based on the user requirements and output it to the excitation module 20; the excitation module 20 is used to implement the connection mode corresponding to the selection signal after receiving the selection signal.

[0080] Understandably, the selection module 30 serves as the interface between the user and the excitation module 20, responsible for receiving user input via some means (such as buttons, touchscreens, remote controls, etc.). These requirements may include selecting different excitation parameters (such as current intensity, frequency, waveform, etc.), selecting different groups of electrodes for excitation, adjusting the excitation time, etc.

[0081] Understandably, the selection module 30 generates corresponding selection signals based on the received user requests. These selection signals, whether digital or analog, are used to instruct the excitation module 20 to implement specific connection methods or excitation parameters.

[0082] Understandably, the selection module 30 outputs the generated selection signal to the excitation module 20. Upon receiving these signals, the excitation module 20 will implement the corresponding connection method or adjust the excitation parameters according to the signal indication.

[0083] In a feasible implementation, this embodiment provides a scheme for adjusting the connection method. The array needle structure further includes: multiple switches; each switch is connected to the needle and the excitation module 20 respectively; the excitation module 20 selects the connection method corresponding to the signal by controlling the conduction state of each switch.

[0084] Understandably, in the array of electrocautery needles, a switch is introduced for each needle or group of needles. These switches are connected to the needles and the excitation module 20 respectively, and are used to control whether the needles receive electrical energy from the excitation module.

[0085] Understandably, the excitation module 20 implements the connection method corresponding to the selection signal by controlling the conduction state of each switch. When a switch is in the conduction state, the corresponding needle or needle group will receive electrical energy from the excitation module and be excited. When a switch is in the off state, the corresponding needle or needle group will not receive electrical energy and will not be excited.

[0086] Therefore, when connected in the third connection method, the time-segmented excitation of each group can be implemented by the time sequence of the on / off state of the switch, so that the electric needles of the same group can receive excitation simultaneously.

[0087] It should be noted that multiple switches can be selected from relays. The specific relays need to take into account factors such as current capacity and voltage level to ensure that they can withstand the current and voltage during the treatment process.

[0088] This embodiment provides an example of stimulating the array electroacupuncture structure described above. The array electroacupuncture structure can be flexibly stimulated according to the user's needs to achieve personalized treatment plans, such as selecting bipolar or unipolar stimulation. At the same time, the safety and stability of the system are effectively guaranteed.

[0089] This application also provides a medical aesthetic device, which has an array electronephrase structure as described above.
