Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a control method for a laser liposuction device and the laser liposuction device itself. Background Technology

[0002] With the development of society and the economy and the improvement of people's living standards, people's material needs have been effectively met. Correspondingly, the proportion of obese people has continued to increase in recent years. The health and aesthetic problems caused by obesity or localized fat accumulation are troubling obese people, which has also brought business opportunities to various weight loss technologies.

[0003] Specifically, various weight loss and fat reduction technologies have emerged on the market, including drug-based weight loss, acupuncture and massage weight loss, radiofrequency lipolysis, ultrasonic lipolysis, and laser lipolysis. Among these, laser lipolysis is widely accepted due to its safety, non-invasiveness, and ability to precisely target fat reduction in specific areas. The working principle of laser lipolysis is to release low-energy laser light, which generates chemical signals within fat cells, breaking down stored triglycerides into free fatty acids and glycerol. These are then released through channels in the cell membrane, thereby reducing fat thickness.

[0004] Furthermore, as the market for laser liposuction devices continues to expand, these devices are also being upgraded. Considering issues such as skin laxity that may occur after laser liposuction, the new generation of laser liposuction devices employs a laser + EMS (Electrical Muscle Stimulation) microcurrent solution. The laser dissolves fat, while the EMS microcurrent tightens muscles, stimulates collagen regeneration, and promotes the elimination of free fatty acids; the two work synergistically to achieve fat reduction, skin tightening, and body sculpting. The EMS microcurrent is delivered through one or more electrodes mounted on the treatment handpiece of the laser liposuction device.

[0005] However, the inventors discovered in the process of realizing the technical solution of this application that although the design of multiple electrodes has achieved the effect of more uniform current density distribution and increased muscle electrical stimulation area, the EMS microcurrent stimulation direction of the EMS microcurrent control scheme in the existing laser fat reduction device cannot adapt to the differences in muscle direction in different parts of the human body, resulting in low shaping accuracy and poor firming effect.

Calculate the second matching degree between the site identification information collected by the multimodal sensor on the treatment handpiece with a low first matching degree and the information of the unidentified fat reduction site; The information of the fat reduction area with the highest matching degree is assigned to the treatment handle with the lowest matching degree.

Detailed Implementation

[0020] To better understand the above-mentioned objectives, features, and advantages of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the technical concept of the embodiments of this application are within the scope of protection of this application.

[0021] To facilitate understanding, the technical concept of the embodiments of this application will first be explained. As mentioned in the background art, the design of multiple electrodes in the EMS microcurrent control scheme of existing laser liposuction devices is usually to achieve a more uniform current density distribution and increase the area of ​​muscle electrical stimulation. Multiple electrodes generally stimulate simultaneously (in this case, the number of electrodes is even, forming electrode pairs) or sequentially according to a set order. The direction of EMS microcurrent stimulation cannot adapt to the differences in muscle direction in different parts of the human body, resulting in low shaping accuracy and poor firming effect. To solve this problem, the applicant proposes a control method for a laser liposuction device. This control method obtains the fat reduction area information of the treatment handle location, and then selects a target electrode that matches the muscle direction of the treatment handle location based on the fat reduction area information, and controls the target electrode to implement EMS microcurrent stimulation. The control method of the laser liposuction device provided in this application embodiment is such that the target electrode for EMS microcurrent stimulation is adapted to the muscle direction at the location of the treatment handpiece, so that the EMS microcurrent is conducted along the direction of muscle fibers, and the muscle fibers contract along their own physiological contraction direction. This improves the accuracy of muscle stimulation and shaping, effectively improves the tightening effect, and has a good tightening effect.

[0022] The embodiments of this application will now be described in more detail with reference to the accompanying drawings.

[0023] This application provides a control method for a laser liposuction device, which is executed by the laser liposuction device.

[0024] See Figure 1 As shown in the figure, the laser liposuction device provided in this application embodiment includes: a main unit 10 and a treatment handpiece 20. The main unit 10 and the treatment handpiece 20 are connected, specifically via a cable, and the main unit 10 provides the treatment handpiece 20 with necessary power signals, control signals, etc., through the cable.

[0025] Specifically, the host 10 structure and hardware of this embodiment can adopt the host of a laser liposuction device in the prior art, typically including a main control board, power supply, display screen 30, etc. The main control board is used to control functions such as laser emission, EMS microcurrent stimulation, safety protection, and user interaction. The power supply is used to convert the mains voltage into the voltage required by the various components in the laser liposuction device. The display screen 30 is used for interaction between the operator and the laser liposuction device, and to display control parameters to the operator. The specific structure and hardware circuit of the host 10 are prior art and do not involve the design points of this embodiment, so they will not be described in detail.

[0026] Furthermore, the main unit 10 is equipped with a socket for the treatment handle 20, which can be connected to the main unit 10 via the socket. The portion of the treatment handle 20 that contacts the skin has a laser irradiation area and multiple electrodes, which surround the laser irradiation area. In practical applications, the number of electrodes is usually four or more, for example, four, five, six, eight, etc. The specific number of electrodes can be determined comprehensively based on factors such as the size of the laser irradiation area. The multiple electrodes can be evenly distributed along the periphery of the laser irradiation area, or their arrangement can be determined comprehensively based on the shape of the laser irradiation area. See also Figure 2 The treatment handpiece shown has eight electrodes 201 surrounding a laser irradiation area formed by laser beads 202. The laser irradiation area contains an array of laser beads that emit low-energy laser light, generating chemical signals within fat cells to break down stored triglycerides into free fatty acids and glycerol. These are then released through channels in the cell membrane, reducing fat thickness and achieving laser lipolysis. The wavelength of the low-energy laser can be selected from one or more of 635nm, 660nm, 808nm, and 980nm. Low-energy lasers have a specific meaning in the medical field, which will not be elaborated upon here.

[0027] Furthermore, the treatment handpiece also includes a control board that receives control signals from the main control board in the host unit to perform laser emission and EMS microcurrent stimulation actions.

[0028] It should be noted that in practical applications, in order to achieve simultaneous treatment of different areas, there can be multiple treatment handles, and the shapes of each treatment handle can be the same or different. In addition, in order to treat small areas with narrow contours, such as the armpit and jawline, the laser liposuction device may also be equipped with a smaller handle for laser treatment only. Since such handles do not have electrodes, they are obviously not suitable for the control method of the laser liposuction device in the embodiments of this application.

[0029] Furthermore, in practical applications, the host 10 in this embodiment may also include other components. For example, it may include a key switch for controlling the power supply of the entire machine, interlocking terminals for implementing safety interlocking, and other components. Since these components and parts are conventional designs in the art and do not involve the design points of the embodiments of the present invention, they will not be described in detail here.

[0030] After a preliminary introduction to the laser liposuction device of this application embodiment, the control method of the laser liposuction device of this application embodiment will be described below.

[0031] See Figure 3 As shown, the control method of the laser liposuction device in this application embodiment may include the following steps: In step S310, information about the fat reduction area where the treatment handle is located is obtained.

[0032] Specifically, the main control board in the host machine obtains the fat reduction area information of the treatment handpiece location. The treatment handpiece location refers to the user's body part corresponding to the portion of the handpiece that contacts the skin, i.e., the area affected by the laser and EMS microcurrent. The fat reduction area information is used to characterize the treatment handpiece location; in practical applications, the fat reduction area information can represent areas such as the abdomen, waist, front of the thigh, outer thigh, upper arm, buttocks, and waist.

[0033] In step S320, a target electrode that matches the muscle direction at the location of the treatment handle is selected from multiple electrodes based on the fat reduction site information.

[0034] Specifically, after the main control board acquires information about the fat reduction areas, it determines the muscle direction of the treatment handle based on this information and the corresponding muscle direction relationships. These muscle direction relationships are pre-established and stored. For example, the abdominal muscles are longitudinal (corresponding to the rectus abdominis), obliquely inward at 45 degrees (corresponding to the internal oblique), and obliquely outward at 45 degrees (corresponding to the external oblique); the upper arm muscles are longitudinal (corresponding to the biceps brachii). Many other correspondences between body areas and muscle directions are common knowledge and will not be elaborated upon here.

[0035] Furthermore, the main control board selects target electrodes from multiple electrodes on the treatment handle that match the muscle direction at the location of the treatment handle, based on the muscle direction. For example, if the treatment handle is located in the abdomen, the main control board selects two longitudinal electrodes and four diagonally intersecting electrodes as target electrodes.

[0036] It should be noted that in practical applications, the operator needs to properly place the treatment handle onto the corresponding area. This ensures a fixed placement angle for the treatment handle. Once the control board determines the muscle direction, it can directly identify the target electrode that matches the muscle direction at the location of the treatment handle. Of course, in principle, specific guidelines for the operator are not required. However, in this case, the main control board needs to obtain the placement angle of the treatment handle using an accelerometer, gyroscope, etc., or by inputting the placement angle through the display interface. The main control board then combines the placement angle and muscle direction to comprehensively determine the target electrode that matches the muscle direction at the location of the treatment handle.

[0037] It should also be noted that, for situations where the operator needs to properly place the treatment handle onto the corresponding area, the correspondence between the target electrode and the fat reduction area can be pre-set. In this way, the main control board can directly determine the target electrode that matches the muscle direction of the area where the treatment handle is located based on the correspondence and the fat reduction area information.

[0038] In step S330, the target electrode is controlled to receive EMS microcurrent stimulation.

[0039] Specifically, after the main control board identifies the target electrode, it sends the target electrode information to the slave control board located in the treatment handpiece. The slave control board selects the corresponding target electrode based on the target electrode information to implement EMS microcurrent stimulation. Each electrode has a corresponding switch branch between the slave control board and the slave control board, and each switch branch has an analog switch. The slave control board controls the on / off state of these analog switches to activate the target electrode. For example, if the treatment handpiece is located on the abdomen, and the main control board selects two vertically aligned electrodes and four diagonally aligned electrodes as target electrodes, the EMS microcurrent stimulation direction will be vertical contraction and diagonal contraction. In practical applications, the frequency, pulse width, and current intensity of the EMS microcurrent can be set by the operator, or the acquisition methods of EMS microcurrent control parameters in other existing technologies can be referenced; this embodiment does not limit the specific parameters.

[0040] In step S340, the laser irradiation area is controlled to emit laser light.

[0041] Specifically, after acquiring the control parameters for laser irradiation, the main control board sends the corresponding control parameters to the slave control board located in the treatment handpiece. The slave control board then controls the laser lamp array in the laser irradiation area to emit laser light based on the received control parameters. The acquisition of the laser irradiation control parameters is existing technology and does not involve the design details of this application's embodiments, so it will not be elaborated upon here.

[0042] Furthermore, in practical applications, the main control board can first control the laser emission area to emit a laser, and then control the implementation of EMS microcurrent stimulation. The duration of laser emission and other control parameters, as well as the duration of EMS microcurrent stimulation and other control parameters, can be set by the operator through the display interface on the screen. Alternatively, different modes can be preset. After the operator selects the mode, the settings for each operation parameter are achieved. The possibility of subsequently using AI (Artificial Intelligence) to determine each control parameter cannot be ruled out. The time difference between laser emission and EMS microcurrent stimulation should not be too long to ensure that the fatty acids released by laser lipolysis can be promptly metabolized and excreted by the muscle contractions generated by EMS microcurrent stimulation. The specific time difference can be a given value or selected by the operator within a certain time range.

[0043] It should be noted that controlling the laser emission from the laser emission zone and implementing EMS microcurrent stimulation can be performed simultaneously. However, in this case, the intensity of both the emitted laser and the intensity of the EMS microcurrent stimulation must be controlled to avoid the impact of muscle contraction on the stability of laser irradiation and to prevent skin thermal damage. In practical implementation, the intensity of the emitted laser and the intensity of the EMS microcurrent stimulation can be coordinated by limiting the adjustment range of the control parameters for different laser control parameters.

[0044] This application provides a control method for a laser liposuction device, comprising: acquiring information about the fat reduction area where the treatment handle is located; selecting a target electrode from multiple electrodes that matches the muscle direction at the treatment handle location based on the fat reduction area information; controlling the target electrode to perform EMS microcurrent stimulation; and controlling the laser irradiation area to emit laser light. The technical solution of this application embodiment, because the target electrode performing EMS microcurrent stimulation matches the muscle direction at the treatment handle location, allows the EMS microcurrent to be conducted along the muscle fiber direction, and the muscle fibers to contract along their own physiological contraction direction, improving the accuracy of muscle stimulation and shaping, effectively improving the firming effect, and achieving excellent firming results.

[0045] Furthermore, in one specific embodiment of this application, a multimodal sensor is provided on the treatment handpiece of the laser liposuction device. In practical applications, the multimodal sensor includes a camera for acquiring image information of the area where the treatment handpiece is located, a curvature sensor (generally a ranging sensor) for acquiring the skin curvature of the area where the treatment handpiece is located, and an attitude sensor for detecting the spatial attitude angle of the treatment handpiece. The attitude sensor can be a gyroscope, accelerometer, etc. Generally, the camera and curvature sensor can be located on the part of the treatment handpiece that contacts the skin, with the lens end faces of the camera and curvature sensor flush with or slightly concave relative to the treatment end face (i.e., the part of the treatment handpiece that contacts the skin), and the attitude sensor located inside the treatment handpiece. Another possible solution is that the camera and curvature sensor are mounted on the side wall of the treatment end face, with the lenses of the camera and curvature sensor facing the skin area, and the attitude sensor located inside the treatment handpiece. Of course, it is possible to locate the attitude sensor outside the treatment handpiece, but for aesthetic and protective purposes, the attitude sensor is preferably located inside the treatment handpiece, and more preferably on the control panel.

[0046] Accordingly, see Figure 4 As shown, step S310 may include: In step S3101, the part identification information collected by the multimodal sensor is obtained.

[0047] Specifically, the part identification information collected by the multimodal sensors is sent from the control board to the main control board. This part identification information includes: image information collected by the camera, attitude information collected by the attitude sensor, and curvature information collected by the curvature sensor.

[0048] In step S3102, the fat reduction area information of the treatment handle is determined based on image information, posture information, and curvature information.

[0049] Specifically, the main control board determines the skin texture, skin color, hair distribution, and / or local features of the treatment handle location based on image information; it determines the spatial posture angle of the treatment handle based on posture information; and it determines the curvature of the treatment handle location based on curvature information. Simultaneously, the main control board pre-stores image features (including skin texture features, skin color features, hair features, and / or local features), spatial posture angle features (specifically, the angular range of the spatial posture angle), and body contour features (specifically, the curvature range) of various body parts. The main control board fuses the determined skin texture, skin color, hair distribution, and / or local features, spatial posture angles, and curvature, along with the image features, spatial posture angle features, and body contour features of various body parts, to determine the fat reduction area information of the treatment handle location.

[0050] In some implementations, the main control board matches the determined spatial pose angles and curvatures with the spatial pose angle features and body contour features of each body part to determine a set of candidate parts that match both spatial pose angles and curvatures. The matching degree is then calculated between the image features of each body part corresponding to the candidate part set and the determined skin texture, skin color, hair distribution and / or local features. The part with the highest matching degree is determined as the final fat reduction part information.

[0051] In other implementations, the main control board calculates the matching degree between the determined skin texture, skin color, hair distribution, and / or local features and the image features of various body parts to obtain the image matching degree; it calculates the matching degree between the determined spatial pose angles and the spatial pose angle features of various body parts to obtain the pose matching degree; and it calculates the matching degree between the determined curvature and the body contour features of various body parts to obtain the curvature matching degree. The image matching degree, pose matching degree, and curvature matching degree are then weighted and fused to obtain the comprehensive matching degree for each body part; the body part with the highest comprehensive matching degree is identified as the fat reduction area information for the location of the treatment handle. The weighting coefficients in the weighted fusion are empirical values.

[0052] Specifically, embodiments of this application may also employ machine learning algorithms to identify the location of the treatment handle. Specifically, a multimodal feature dataset covering various fat-reducing areas of the body (such as the abdomen, waist, thighs, upper arms, and buttocks) can be pre-constructed. This multimodal feature dataset is then used to pre-train the machine learning algorithm, optimizing and validating the parameters to ensure the model has reliable site recognition capabilities. The multimodal feature dataset must include image features, spatial pose features, and body contour features corresponding to each body part. In practical applications, the machine learning algorithm used in embodiments of this application may be one or more of convolutional neural network algorithms, random forest algorithms, and support vector machine algorithms.

[0053] During the recognition phase, the main control board inputs the determined skin texture, skin color, hair distribution and / or local features, as well as the corresponding spatial pose angle and curvature, into the pre-trained machine learning algorithm model, and outputs information on the fat reduction area where the treatment handle is located.

[0054] In this specific implementation, the main control board comprehensively determines the fat reduction area information of the treatment handpiece based on the image information, posture information and curvature information collected by the multimodal sensor. Compared with simply relying on image information to identify fat reduction area information, it can more accurately identify fat reduction area information and avoid the problem of mismatch between the EMS microcurrent stimulation direction and the muscle direction of the area due to incorrect fat reduction area identification.

[0055] Furthermore, considering that in practical applications, different users may undergo treatment in different postures such as lying down, prone, or sitting, and that the treatment posture has a significant impact on the posture information collected by the posture sensor, therefore, in one specific embodiment of this application, the control method of the laser liposuction device of this application may further include: Obtain the user's treatment posture information.

[0056] The user's treatment posture information can be set by the operator through the display screen interface and then acquired by the main control board.

[0057] Accordingly, step S3102 may include: The fat reduction area information of the treatment handle location is determined based on image information, posture information, curvature information, and treatment posture information.

[0058] Specifically, for different treatment postures, image features, spatial posture angle features, and body contour features of various body parts can be stored separately. Then, the main control board determines the skin texture, skin color, hair distribution, and / or local features of the treatment handle location based on the image information; determines the spatial posture angle of the treatment handle based on the posture information; and determines the curvature of the treatment handle location based on the curvature information. Finally, the main control board fuses the determined skin texture, skin color, hair distribution, and / or local features, spatial posture angle, and curvature, as well as the image features, spatial posture angle features, and body contour features of various body parts to determine the fat reduction area information of the treatment handle location.

[0059] Similarly, an alternative approach is to train machine learning algorithm models for different treatment postures, and then use these models to identify fat reduction areas at the location of the treatment handle.

[0060] This specific implementation takes into account the impact of the user's treatment posture on the data collected by the multimodal sensors, and the information on the fat reduction area determined by combining the treatment posture information is more accurate.

[0061] Furthermore, considering the need for simultaneous fat reduction in multiple body areas, multiple treatment handpieces can be configured in the laser liposuction device. In this case, considering the possibility that different treatment handpieces might identify the same fat reduction area—for example, when the user is lying down, the curvature and posture of the flank and abdomen are similar, and their skin texture and other features are highly similar—there is a possibility of misidentification. Therefore, in one specific embodiment of this application, the control method of the laser liposuction device may further include: If it is determined that the fat reduction area information of two treatment handles is the same, remind the operator to manually determine the corresponding fat reduction area information.

[0062] Specifically, the display screen can prompt the operator to manually determine the corresponding fat reduction area information.

[0063] In this specific implementation method, errors in the identification of fat reduction area information are corrected through manual intervention, so that EMS microcurrent stimulation that matches the muscle direction of the area can be performed subsequently.

[0064] Furthermore, in addition to using manual intervention to correct identification errors in fat reduction area information, automatic correction is also possible. Specifically, in one specific embodiment of this application, when there are multiple treatment handpieces, the control method of the laser fat reduction device of this application embodiment may further include: When it is determined that the fat reduction area information of two treatment handles is the same, the first matching degree between the area identification information collected by the multimodal sensors on the two treatment handles and the determined fat reduction area information is calculated; the determined fat reduction area information is assigned to the treatment handle with the higher first matching degree; the second matching degree between the area identification information collected by the multimodal sensors on the treatment handle with the lower first matching degree and the unidentified fat reduction area information is calculated; the fat reduction area information with the highest second matching degree is assigned to the treatment handle with the lower first matching degree.

[0065] Specifically, for each treatment handpiece corresponding to the body part identification information, the main control board calculates the matching degree between the skin texture, skin color, hair distribution, and / or local features determined from the image information and the image features corresponding to the fat reduction area information, obtaining the image matching degree; it calculates the matching degree between the spatial posture angle determined from the posture information and the spatial posture angle features corresponding to the fat reduction area information, obtaining the posture matching degree; and it calculates the matching degree between the determined curvature and the body contour features corresponding to the fat reduction area information, obtaining the curvature matching degree. The image matching degree, posture matching degree, and curvature matching degree are then weighted and fused to obtain the comprehensive matching degree of each body part as the first matching degree. The weighting coefficients in the weighted fusion are empirical values.

[0066] Then, the size of the two first matching degrees is compared, and the identified fat reduction area information is assigned to the treatment handle with the higher first matching degree.

[0067] Furthermore, for treatment handles with low first-match scores, a second match score is calculated between the corresponding site identification information and unidentified fat reduction site information. Here, unidentified fat reduction site information refers to fat reduction site information not covered by the currently identified fat reduction site information. The calculation process for the second match score is the same as that for the first match score, and will not be repeated here. Finally, the fat reduction site information with the highest second match score is assigned to the treatment handle with low first-match scores.

[0068] In this specific implementation, when it is determined that the fat reduction area information of two treatment handles is the same, the fat reduction area information of the treatment handle is determined by matching degree calculation. This is more intelligent than the method of correcting the identification error of fat reduction area information by manual intervention, and saves the operator's operation steps.

[0069] Optionally, in one specific embodiment of this application, step S310 may include: Receives information about the fat reduction areas input by the operator.

[0070] Specifically, the operator can input the corresponding fat reduction area information through the display screen interface, which is then transmitted to the main control board. For laser fat reduction devices that can interact with the host via an APP (Application), mini-program, etc., the operator can also input the fat reduction area information through the corresponding APP or mini-program.

[0071] In this specific implementation, the operator inputs information about the fat reduction area, providing support for the subsequent matching of the EMS microcurrent stimulation direction with the muscle direction of the area.

[0072] Furthermore, considering that when there are multiple treatment handles, and the method of using operator-inputted fat reduction area information requires the operator to associate the treatment handles with the current input interface, in a specific embodiment of this application, the step of receiving operator-inputted fat reduction area information may include: Acquire the handpiece test signal input by the operator so that the operator can determine the target treatment handpiece based on the response of each treatment handpiece to the handpiece test signal; receive the fat reduction area information input by the operator based on the location of the target treatment handpiece.

[0073] Specifically, the operator can send a handpiece test signal to the main control board via the display screen, an app, or a mini-program. The main control board forwards the handpiece test signal to the slave control board located in the corresponding treatment handpiece. The slave control board controls the treatment handpiece to generate light or sound signals that can be recognized by the operator. The operator then identifies the target treatment handpiece for which fat reduction area information needs to be entered and inputs the fat reduction area information based on the location of the target treatment handpiece. After the operator completes the fat reduction area information input for one treatment handpiece, they can select the next treatment handpiece for which fat reduction area information needs to be entered by sliding or using the handpiece selection control on the interface, until the fat reduction area information for all treatment handpieces used for the current treatment has been entered.

[0074] In this specific implementation, the operator can determine the target treatment handle that needs to input fat reduction area information based on the handle test signal, and complete the input of fat reduction area information for each treatment handle in a multi-treatment handle scenario.

[0075] Optionally, in one specific embodiment of this application, step S330 may include: The control parameters of the EMS microcurrent are determined based on the information of the fat reduction area; the target electrode is controlled to implement EMS microcurrent stimulation according to the control parameters.

[0076] Specifically, the main control board's memory can pre-store the correspondence between fat reduction site information and EMS microcurrent control parameters. The main control board determines the required EMS microcurrent control parameters for the treatment handpiece location based on the fat reduction site information and this correspondence. Then, the main control board sends the control parameters to the slave control board, which controls the target electrode to perform EMS microcurrent stimulation according to these parameters. The correspondence between the fat reduction site information and the EMS microcurrent control parameters can be obtained through actual testing or based on empirical values.

[0077] This specific implementation adapts different EMS microcurrent control parameters to different parts, resulting in better compatibility between the EMS microcurrent control parameters and the parts, and a better user experience.

[0078] Furthermore, considering that different users have different tolerances to EMS microcurrents, adapting the same control parameters to different users would obviously lead to increased discomfort for some users. Therefore, in a specific embodiment of this application, the step of determining the control parameters of the EMS microcurrent based on the fat reduction area information may include: The control parameters of the EMS microcurrent are determined based on information about the fat reduction area and the individual user information.

[0079] The individual user information may include one or more parameters such as age, gender, and tolerance level. This individual user information can be entered by the operator based on the results of inquiries and tests before formal treatment.

[0080] Specifically, the main control board determines the basic control parameters of the EMS microcurrent based on information about the fat reduction area and the correspondence between this information and the control parameters of the EMS microcurrent. Then, the main control board determines correction parameters based on individual user information, adjusts the basic control parameters accordingly, and uses the adjusted parameters as the control parameters for the EMS microcurrent. For example, if the basic frequency for the abdomen is 60Hz, the basic pulse width is 200μS, and the basic current intensity is 20mA, and the user has a high tolerance level, is male, and is 25 years old, a comprehensive decision is made to increase all basic control parameters by 10%. The final control parameters would then be a frequency of 66Hz, a pulse width of 220μS, and a current intensity of 22mA. This comprehensive determination typically involves a weighted average to determine the impact of each user's individual information on the adjustment ratio of the basic control parameters.

[0081] This specific implementation method fine-tunes the EMS microcurrent control parameters based on individual user information, thereby improving user comfort and safety.

[0082] It should be noted that the foregoing method embodiments are some embodiments of the control method of the laser liposuction device of this application, and other embodiments may also exist.

[0083] For example, in practical applications, bio-electrical impedance (BIA) measurement circuits can be installed on the electrodes of the treatment handpiece to measure the thickness of the fat layer at the corresponding site. The main control board determines the control parameters of the EMS microcurrent based on the fat reduction site information and the fat layer thickness. By taking the fat layer thickness into account in the determination process of the EMS microcurrent control parameters, the final determined control parameters are more suitable for the physiological parameters of the corresponding site. Similar to the method of correcting the basic control parameters of the EMS microcurrent using individual user information, the basic control parameters of the EMS microcurrent can also be adjusted based on the fat layer thickness to ultimately determine the control parameters of the EMS microcurrent used in practice.

[0084] For example, the control method of the laser liposuction device in the embodiments of this application may further include: During EMS microcurrent stimulation, the control board collects the skin contact resistance of the treatment handpiece in real time and determines its relationship with a preset threshold. If the skin contact resistance exceeds the preset threshold, EMS microcurrent stimulation is immediately stopped, and an alarm signal is sent to the main control board. The main control board then displays the alarm on the screen, prompting the user to adjust the fit of the treatment handpiece. The preset threshold is an empirical value.

[0086] In practical applications, the memory and processor are usually located on the main control board in the host computer.

The technical solution of this application embodiment, because the target electrode for implementing EMS microcurrent stimulation matches the muscle direction of the area where the treatment handpiece is located, allows the EMS microcurrent to be conducted along the muscle fiber direction, and the muscle fibers to contract along their own physiological contraction direction, improving the accuracy of muscle stimulation and shaping, effectively improving the firming effect, and achieving excellent firming results.
