Description

Technical Field

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

[0002] For thousands of years, the pursuit of beauty has been an integral part of human social development. As living standards improve, more and more people are focusing on maintaining and reshaping their skin and figure in pursuit of youthful beauty. Correspondingly, advancements in technology and commerce have provided people with more choices. Specifically, in addition to traditional beauty methods such as skincare products, a plethora of medical devices and equipment have emerged for skin rejuvenation, hair removal, and fat reduction.

[0003] In particular, some commercial or medical devices are equipped with multiple treatment handles to achieve better cosmetic results or higher treatment efficiency. For example, some laser liposuction devices are equipped with 6, 8, 10 or even more treatment handles to allow the laser to treat as many areas as possible at once. Vacuum negative pressure multifunctional beauty devices (commonly known as large bubbles) and microbubble skin cleansing devices (commonly known as small bubbles) are also equipped with multiple treatment handles to achieve functions such as deep cleansing, skin scraping, oxygen infusion, nutrient delivery, and hot and cold compresses.

[0004] In the process of realizing the technical solution of this application, the inventors discovered that in the prior art, these medical devices with multiple treatment handles connect each treatment handle to the main control board and switching power supply in the host through a separate cable. Due to the large number of treatment handles, the internal wiring harness of the host is messy and occupies a lot of space. Furthermore, the cables from the outside of the host to the treatment handles are excessive and long, easily leading to friction and interference between the cables, affecting user experience and cable lifespan.

Detailed Implementation

[0019] 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.

[0020] For ease of understanding, the technical concept of the embodiments of this application will first be described. As mentioned in the background art, existing medical devices with multiple treatment handles have each treatment handle connected to the main control board and switching power supply in the host via a separate cable. Due to the large number of treatment handles, the internal wiring harness of the host is messy and occupies a lot of space. Furthermore, the cables between the host and the treatment handles are too numerous and too long, which can easily lead to friction and interference between the cables, affecting the user experience and cable life.

[0021] To address this issue, the applicant proposes a medical device comprising a main unit, multiple treatment handles, and at least one adapter. Each adapter is connected to the main control board and a first switching power supply in the main unit via a main cable. Each adapter also has at least two branch cables, each corresponding to a treatment handle, and the adapter is electrically connected to the corresponding treatment handle via the branch cables. In the medical device provided by this application, since the main control board and the first switching power supply in the main unit are connected to the adapter via the main cable, and each adapter has at least two branch cables, each corresponding to a treatment handle, the number of main cables is at most half the number of treatment handles, thus reducing the number of main cables. On the one hand, the reduction in main cables reduces the number of wiring harnesses connected to the main cables inside the main unit, simplifying the internal wiring and reducing space occupation. On the other hand, the connection method of the main and branch cables allows for the grouping of treatment handles and cables. Furthermore, while reducing the number of main cables, the length of the branch cables is effectively shortened, significantly reducing tangling between cables, lowering friction and interference, improving user experience, and extending cable life.

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

[0023] See Figure 1 The diagram shown is a structural schematic of a medical device according to an embodiment of this application. The medical device includes a main unit 10, multiple treatment handles 20, and at least one adapter 30. Each adapter 30 is connected to the main control board and a first switching power supply in the main unit 10 via a main cable 40. Each adapter 30 is also connected to at least two branch cables 50, each branch cable 50 corresponding to one treatment handle 20. The adapter 30 is electrically connected to the corresponding treatment handle 20 via the branch cables 50. It is evident that the number of adapters 30 is the same as the number of main cables 40, and there is a one-to-one correspondence between the adapters 30 and the main cables 40.

[0024] Specifically, in practical applications, the host 10 in this embodiment is the host of a medical device with multiple treatment handles. For example, the host 10 in this embodiment can be the host of a laser liposuction device, the host of a vacuum negative pressure multifunctional beauty device, or the host of a microbubble skin cleansing device. The structure and hardware of the host 10 in this embodiment can basically adopt the host of a medical device with multiple treatment handles in the prior art, typically including a main control board, a power supply (i.e., a first switching power supply), a display screen, etc. The difference is that the number of signal lines of the main control board and power lines of the first switching power supply in this embodiment matches the number of main cables. Correspondingly, the number of signal interfaces of the main control board can also be reduced, and the number of power terminals of the first switching power supply can also be reduced. In addition, the number of sockets connecting the host to the main cable is also reduced. The main control board is used to control the treatment functions, safety protection, user interaction, etc. of the treatment handles; the first switching power supply is used to convert the mains voltage into the voltage required by the various components in the medical device; and the display screen is used for interaction between the operator and the medical device, as well as to display treatment parameters to the operator. The specific structure and hardware circuits of other parts of the host 10 that are not described are existing technologies and do not involve the design points of the embodiments of this application, so they will not be described here.

[0025] Furthermore, the treatment handpiece 20 can be a treatment handpiece from existing medical device equipment with multiple treatment handpieces. The number of treatment handpieces is determined according to the design requirements of the medical device equipment, for example, it can be 6, 8, 10, or 12, etc., and each treatment handpiece can be the same or different. The treatment handpiece 20 may include a handpiece controller, a treatment head required for treatment, and other components, specifically related to the function of the treatment handpiece. Taking the treatment handpiece of a laser lipolysis device as an example, in addition to the handpiece controller, the treatment handpiece also includes a laser array for laser treatment. For treatment handpieces in laser lipolysis devices capable of performing EMS (Electrical Muscle Stimulation) microcurrent treatment, the treatment handpiece also includes electrodes surrounding the laser array. More specific structures and hardware circuits of the treatment handpiece 20 can be found in existing technologies, and will not be elaborated here.

[0026] Furthermore, the number of connecting cables on each adapter 30, i.e. the number of treatment handles, can be 2, 3, or 4, etc. The number of adapters 30 is determined based on the number of treatment handles and the number of treatment handles connected to each adapter 30. Figure 1 In the illustrated embodiment, there are two adapters, and each adapter 30 is connected to four treatment handles, but this embodiment does not limit this.

[0027] See Figure 2As shown, each adapter 30 may include: an adapter processor 301, a first serial port circuit 302, and a number of second serial port circuits 303 connected to the same number of treatment handles as the adapter. The adapter processor 303 is connected to the main cable via the first serial port circuit and to the corresponding branch cable via each second serial port circuit 303. The adapter processor 301 receives control signals from the main control board via the first serial port circuit 302 and sends control parameter information to the corresponding branch cable and treatment handle via the second serial port circuits 303. The first serial port circuit 302 converts the analog signals of the control signals transmitted on the main cable into digital signals that the adapter processor 301 can directly process. The second serial port circuit 303 converts the digital signals of the control parameter information to be sent by the adapter processor 301 into analog signals that can be transmitted on the branch cable. In practical applications, the first serial port circuit 302 and the second serial port circuit 303 can directly use commercially available analog-to-digital converter circuits, which will not be elaborated here. It should be noted that in practical applications, the adapter 30 also includes auxiliary circuits such as a power conversion circuit. For example, the power auxiliary circuit is used to convert the power signal transmitted by the main cable into the voltage required by the adapter processor 301, the first serial port circuit 302, and the second serial port circuit 303. These auxiliary circuits are existing technologies and will not be described in detail here. Generally, the adapter processor 301, the first serial port circuit 302, the second serial port circuit 303, and each auxiliary circuit are mounted on a circuit board. This circuit board and the housing protecting the circuit board together constitute the adapter.

[0028] Furthermore, the number of treatment handles that can be connected to different adapters can be the same or different. For example, see Figure 3 The diagram shows a schematic of the laser liposuction device developed by the applicant using the technical solution of this application. The laser liposuction device includes a main unit 310, adapters, and treatment handpieces. The device includes 10 treatment handpieces, of which 8 treatment handpieces 3301 are conventional treatment handpieces (4 are shown in the diagram), and the remaining 2 treatment handpieces 3302 are smaller handpieces designed for treating small, narrow areas such as the armpits and jawline. The 8 conventional treatment handpieces 3301 are connected to 2 adapters 3201 with 4 branch cables, and the 2 smaller handpieces 3302 are connected to 1 adapter 3202 with 2 branch cables.

[0029] Both the main cable 40 and the branch cable 50 include power lines and signal lines for transmitting signals and power. The main cable 40 and the branch cable 50 use existing technologies, which will not be described in detail here.

[0030] Furthermore, each adapter 30 is used to acquire control signals sent by the main control board via the main cable 40.

[0031] Specifically, the operator can input treatment parameters through the display screen and transmit them to the main control board. For medical devices that can interact with the host via an APP (Application), mini-program, etc., the operator can also input treatment parameters through the corresponding APP or mini-program and transmit them to the main control board. The treatment parameters input by the operator include treatment handle selection information and control parameters for the treatment handle. Specific treatment parameters are related to the treatment handle selected by the operator. For example, for the cleaning handle of a vacuum negative pressure multifunctional beauty device, the corresponding control parameters include negative pressure and solution flow rate; for the skin scraping handle of a vacuum negative pressure multifunctional beauty device, the corresponding control parameters include energy and frequency; for the treatment handle of a laser liposuction device, the corresponding control parameters include the wavelength, power, and energy density of the selected laser; for a laser liposuction device with EMS microcurrent function, the corresponding control parameters also include the frequency, pulse width, and current intensity of the EMS microcurrent. More specific control parameters can be found in existing technologies and will not be elaborated here.

[0032] It should be noted that the method of inputting treatment parameters by the operator differs for different medical devices. For example, for a vacuum negative pressure multifunctional beauty instrument or a microbubble skin cleansing instrument, the treatment handpieces have a treatment sequence depending on the treatment purpose. Therefore, the treatment parameters input by the operator each time are for one treatment handpiece. After the treatment of that handpiece is completed, the operator inputs the treatment parameters for the next treatment handpiece according to the treatment sequence. As another example, for a laser liposuction device, to achieve simultaneous treatment of different areas, multiple selected treatment handpieces are usually required to work simultaneously. Therefore, in this case, the operator needs to input the treatment parameters for multiple treatment handpieces at once, specifically by selecting multiple treatment handpieces at once, i.e., inputting multiple handpiece selection information. Simultaneously, the operator needs to input control parameters for each selected treatment handpiece. It is evident that when the operator selects multiple treatment handpieces at once, there is a definite correspondence between the handpiece selection information and the control parameters. In particular, the handpiece selection information and control parameters can be a one-to-one correspondence, or multiple handpiece selection information corresponding to the same adapter 30 can have the same control parameters.

[0033] Furthermore, the main control board generates control signals based on the treatment parameters input by the operator. These control signals include the main control board determining handle identification information based on the handle selection information input by the operator, and generating control parameter information based on the control parameters input by the operator.

[0034] It is evident that the number of control signals generated varies depending on how the operator inputs treatment parameters. Specifically, when the operator inputs treatment parameters for one treatment handle at a time, the main control board generates one control signal each time. When the operator needs to input treatment parameters for multiple treatment handles simultaneously, the number of control signals generated by the main control board each time is the same as the number of treatment handles selected by the operator. When the main control board generates multiple control signals, the handle identification information and control parameter information for each control signal are grouped and associated.

[0035] Furthermore, the main control board determines the corresponding adapter for each control signal based on the control signal and a preset correspondence, and then sends the control signal to the corresponding adapter. The preset correspondence can be between handle identification information and adapters, or between control parameter information and adapters. It should be noted that when there are multiple control signals, the main control board needs to determine the adapter corresponding to each control signal and send each control signal to the corresponding adapter.

[0036] Furthermore, the adapter receives the control signals sent by the main control board via the main cable. It is evident that if the main control board generates one control signal at a time, only the adapter corresponding to that control signal can receive it. If the main control board generates multiple control signals at once, the adapter corresponding to each control signal can receive the control signals sent by the main control board.

[0037] After the adapter receives the control signal, each adapter is also used to determine the target treatment handle based on the handle identification information and send the control parameter information to the target treatment handle through the corresponding branch cable.

[0038] Specifically, the adapter is pre-configured with a mapping between handle identification information and treatment handles. The adapter determines the target treatment handle based on the handle identification information and this mapping. Then, it sends the control parameter information to the target treatment handle via the corresponding branch cable. Clearly, when the adapter receives more than one control signal, it determines the corresponding target treatment handle based on the handle identification information in each control signal and sends the control parameter information to each target treatment handle via the corresponding branch cable.

[0039] Furthermore, the target treatment handpiece is used to output treatment signals to the user's skin in contact with the target treatment handpiece based on control parameter information.

[0040] Specifically, the target treatment handpiece includes a handpiece control board. The handpiece processor on the control board receives control parameter information via a corresponding serial port circuit. The handpiece processor uses this control parameter information to control the corresponding drive circuit to output a treatment signal to the user's skin in contact with the target treatment handpiece. In other words, the handpiece processor uses the control parameter information to control the corresponding drive circuit to output a treatment signal to act on the user's skin in contact with the target treatment handpiece. The serial port circuit and drive circuit mentioned here are hardware circuits already present in existing treatment handpieces and will not be described in detail here.

[0041] The medical device provided in this application includes a main unit, multiple treatment handles, and at least one adapter. Each adapter is connected to the main control board and a first switching power supply in the main unit via a main cable. Each adapter also has at least two branch cables, each corresponding to a treatment handle, and the adapter is electrically connected to the corresponding treatment handle via the branch cables. Each adapter is used to acquire control signals sent by the main control board via the main cable. The control signals include handle identification information and control parameter information. Each adapter is also used to determine a target treatment handle based on the handle identification information and send the control parameter information to the target treatment handle via the corresponding branch cable. The target treatment handle is used to output a treatment signal to the user's skin in contact with the target treatment handle based on the control parameter information. Because the main control board and the first switching power supply in the main unit are connected to the adapter via the main cable, and each adapter has at least two branch cables, each corresponding to a treatment handle, the number of main cables is at most half the number of treatment handles, thus reducing the number of main cables. On the one hand, the reduction in the number of main cables results in a corresponding reduction in the number of internal wiring harnesses connected to the main cables, simplifying the internal wiring and reducing space occupation. On the other hand, the connection method of main cables and branch cables enables the grouping of treatment handpieces and cables. Furthermore, while the number of main cables is reduced, the length of branch cables is effectively shortened, which can significantly reduce tangling between cables, reduce friction and interference, improve user experience, and extend cable life.

[0042] Furthermore, considering that hardware circuit failures between the host and the treatment handpiece, DAC (Digital-to-Analog Converter) chip failure on the main control board, and main control program crashes on the main control board can lead to uncontrolled output from the treatment handpiece, seriously affecting user safety, therefore, in one specific embodiment of this application, the host of the medical device device may further include: a functional safety board.

[0043] Specifically, see Figure 4 The diagram shown is a wiring diagram of a medical device according to an embodiment of this application. Figure 4The power lines of the first switching power supply 120 are routed through the functional safety board 130 and then integrated into the main cable along with the signal lines of the main controller 110. The power supply from the first switching power supply 120 in the host 10 is transmitted to the main cable via the functional safety board 130, which contains an ADC (Analog-to-Digital Converter) circuit and a safety processor.

[0044] Furthermore, the safety processor is used to collect the power supply parameters provided by the first switching power supply 120 to the adapter 20 through the ADC circuit, determine whether a first power failure has occurred based on the power supply parameters collected by the ADC circuit, and cut off the power supply to the main cable when a first power failure occurs.

[0045] Specifically, the safety processor can be an MCU (Microcontroller Unit), and the ADC circuit can be an existing ADC circuit. The safety processor uses the ADC circuit to collect power supply parameters such as voltage and current supplied by the first switching power supply 120 to the adapter 20, and determines whether these power supply parameters exceed a first preset range. If the power supply parameters exceed the first preset range, a first power fault is identified, and the power supply to the main cable is cut off upon the occurrence of the first power fault. Generally, the first preset range is an empirical or calibrated range, and the types of first power faults include overvoltage, undervoltage, and overcurrent faults. An electronic switch is installed between the input and output of the power line on the functional safety board to cut off the power supply to the main cable.

[0046] It should be noted that the number of ADC circuits is the same as the number of adapter boards and they correspond one-to-one. Each ADC circuit is used to collect the power signal flowing to the corresponding adapter board.

[0047] In this specific embodiment, the functional safety board can collect the power signal / power supply parameters flowing from the first switching power supply to the adapter in real time through the ADC circuit. Since the functional safety board directly collects the signal on the power line, even if there is a hardware circuit failure between the host and the treatment handpiece, a DAC chip failure on the main control board, or a crash in the main control program of the main control board, the functional safety board can promptly identify power faults such as overvoltage, undervoltage, and overcurrent, and then cut off the power supply to the main cable to block the spread of faults from the hardware link.

[0048] Furthermore, since the power signal supplied by the first switching power supply to the main cable is related to the control state of the treatment handle, in one specific embodiment of this application, the functional safety board is also used to obtain control parameter information from the main control board; the safety processor is also used to determine whether a power failure has occurred based on the power supply parameters and control parameter information collected by the ADC circuit, and to cut off the power supply to the main cable when a second power failure occurs.

[0049] Specifically, the functional safety board pre-stores the correspondence between control parameters and a second preset range. After the functional safety board obtains the control parameter information, the safety processor determines the second preset range based on this correspondence and the control parameter information. It then determines whether the power supply parameter exceeds the second preset range. If the power supply parameter exceeds the second preset range, a second power fault is determined, and the power supply to the main cable is cut off upon the occurrence of the second power fault. The correspondence between the control parameters and the second preset range can be obtained through calibration or based on test data.

[0050] It should be noted that in practical applications, the judgment of the first power failure and the second power failure are performed simultaneously. In this way, the functional safety board can identify the first power failure under abnormal conditions of the main control board, such as the failure of the DAC chip of the main control board or the crash of the main control program of the main control board, as well as the second power failure when the actual output of the treatment handle is different from the expected output.

[0051] This specific implementation can accurately identify power faults when the actual output of the treatment handpiece differs from the expected output, facilitating timely troubleshooting and preventing harm to the user.

[0052] Furthermore, when the medical device is a laser liposuction device, because the laser drive requires significant power, if both the treatment handpiece and the functional safety board use a first switching power supply, the high-power drive signal from the treatment handpiece will interfere with the functional safety board. However, the functional safety board is quite sensitive to external interference. To ensure the reliability of the functional safety board, please refer to [further details omitted]. Figure 4 As shown in one specific embodiment of this application, when the medical device is a laser liposuction device, the main unit may further include a second switching power supply 140. The power output of the second switching power supply 140 is adapted to the functional safety board 130 and is used to supply power to the functional safety board. Specifically, the second switching power supply is used to convert the mains voltage into the voltage required by the functional safety board.

[0053] Since a higher power output from a switching power supply results in greater interference to the functional safety board, in this specific embodiment, the power output of the second switching power supply 140 is matched with that of the functional safety board 130 to minimize interference to the functional safety board 130 caused by the operation of the second switching power supply 140 itself.

[0054] In this specific embodiment, by configuring a second switching power supply with power adaptation for the functional safety board, interference to the functional safety board is reduced and the reliability of the functional safety board is improved.

[0055] Optionally, see [link to relevant documentation] Figure 4As shown in one specific embodiment of this application, the main unit may further include: a key switch 150, an emergency stop switch 160, and a relay 170. The second switching power supply 140 is connected to the first switching power supply 120 sequentially via the key switch 150, the emergency stop switch 160, and the relay 170. In actual use, when the emergency stop switch 160 is not pressed, the key switch 150 is closed, the contacts of the relay 170 are engaged, and the mains voltage is supplied to the first switching power supply 120, which powers the main control board, display screen, adapter, and treatment handle, etc.

[0056] In this specific embodiment, the second switching power supply 140 is connected to the first switching power supply 120 sequentially via a key switch 150, an emergency stop switch 160, and a relay 170. This allows the low-voltage drive grid voltage output from the second switching power supply 140 to be connected to the first switching power supply 120, preventing the operator from directly contacting high voltage and improving safety.

[0057] Furthermore, corresponding to the foregoing device embodiments, this application also discloses a control method, which is applied to the medical device equipment described in any of the foregoing device embodiments. See also Figure 5 As shown, the control method in this application embodiment may include: In step S510, the main control board generates control signals based on the treatment parameters input by the operator.

[0058] Specifically, the operator can input treatment parameters through the display screen and transmit them to the main control board. For medical devices that can interact with the host via an APP (Application), mini-program, etc., the operator can also input treatment parameters through the corresponding APP or mini-program and transmit them to the main control board. The treatment parameters input by the operator include treatment handle selection information and control parameters for the treatment handle. Specific treatment parameters are related to the treatment handle selected by the operator. For example, for the cleaning handle of a vacuum negative pressure multifunctional beauty device, the corresponding control parameters include negative pressure and solution flow rate; for the skin scraping handle of a vacuum negative pressure multifunctional beauty device, the corresponding control parameters include energy and frequency; for the treatment handle of a laser liposuction device, the corresponding control parameters include the wavelength, power, and energy density of the selected laser; for a laser liposuction device with EMS microcurrent function, the corresponding control parameters also include the frequency, pulse width, and current intensity of the EMS microcurrent. More specific control parameters can be found in existing technologies and will not be elaborated here.

[0059] It should be noted that the method of inputting treatment parameters varies depending on the medical device. For example, for a vacuum negative pressure multifunctional beauty instrument or a microbubble skin cleansing instrument, the treatment handpieces have a treatment sequence depending on the treatment purpose. Therefore, the operator inputs treatment parameters for one handpiece at a time. After the treatment on that handpiece is completed, the operator inputs the treatment parameters for the next handpiece in the treatment sequence. As another example, for a laser liposuction device, to achieve simultaneous treatment of different areas, multiple selected handpieces are usually required to work simultaneously. Therefore, in this case, the operator needs to input treatment parameters for multiple handpieces at once, specifically by selecting multiple handpieces at once, i.e., inputting multiple handpiece selection information. Simultaneously, the operator needs to input control parameters for each selected handpiece. Clearly, when the operator selects multiple handpieces at once, there is a definite correspondence between the handpiece selection information and the control parameters. Specifically, the handpiece selection information and control parameters can be a one-to-one correspondence, or multiple handpiece selection information corresponding to the same adapter can have the same control parameters.

[0060] Furthermore, the main control board generates control signals based on the treatment parameters input by the operator. These control signals include the main control board determining handle identification information based on the handle selection information input by the operator, and generating control parameter information based on the control parameters input by the operator.

[0061] It is evident that the number of control signals generated varies depending on how the operator inputs treatment parameters. Specifically, when the operator inputs treatment parameters for one treatment handle at a time, the main control board generates one control signal each time. When the operator needs to input treatment parameters for multiple treatment handles simultaneously, the number of control signals generated by the main control board each time is the same as the number of treatment handles selected by the operator. When the main control board generates multiple control signals, the handle identification information and control parameter information for each control signal are grouped and associated.

[0062] In step S520, the main control board determines the target adapter based on the control signal and the preset correspondence.

[0063] Specifically, the main control board determines the target adapter corresponding to the control signal based on the control signal and a preset correspondence, and then sends the control signal to the corresponding target adapter. The preset correspondence can be between handle identification information and adapters, or between control parameter information and adapters. It should be noted that when there are multiple control signals, the main control board needs to determine the target adapter corresponding to each control signal and send each control signal to the corresponding target adapter.

[0064] In step S530, the main control board sends control signals to the target adapter via the main cable.

[0065] Specifically, the target adapter receives the control signals sent by the main control board via the main cable. It is obvious that if the main control board generates one control signal at a time, only the target adapter corresponding to that control signal can receive it. If the main control board generates multiple control signals at once, the target adapter corresponding to each control signal can receive the control signals sent by the main control board.

[0066] It should also be noted that when multiple handle selection information corresponding to the same adapter has the same control parameters, and the preset correspondence is between control parameter information and adapters, since the treatment handles connected to the same adapter have the same control parameters, the same target adapter can acquire the control parameter information only once. In this case, different control signal transmission methods can be used depending on the storage format of the multiple control signals corresponding to the same target adapter. For example, if each control signal stores handle identification information and control parameter information separately, the main control board can send the control parameter information of one control signal corresponding to the same target adapter to the target adapter, and also send the handle identification information from each control signal to the target adapter. As another example, if each control signal only stores handle identification information, and each control signal is associated with common control parameter information, the main control board can send the commonly associated control parameter information from multiple control signals to the target adapter, and also send the handle identification information from each control signal to the target adapter. Obviously, in this case, the control signals belonging to the same target adapter share the same control parameter information.

[0067] In step S540, the target adapter determines the target treatment handle based on the handle identification information and sends the control parameter information to the target treatment handle through the corresponding branch cable.

[0068] Specifically, the target adapter is pre-configured with a mapping between handle identification information and treatment handles. The adapter determines the target treatment handle based on the handle identification information and this mapping. Then, it sends the control parameter information to the target treatment handle via the corresponding branch cable. Clearly, when the target adapter receives more than one control signal, it determines the corresponding target treatment handle based on the handle identification information in each control signal and sends the control parameter information to each target treatment handle via the corresponding branch cable.

[0069] In step S550, the target treatment handle outputs a treatment signal to the user's skin in contact with the target treatment handle according to the control parameter information.

[0070] Specifically, the target treatment handle is equipped with a handle control board. The handle processor in the handle control board receives control parameter information through a corresponding serial port circuit. The handle processor uses the control parameter information to control the corresponding drive circuit to output a treatment signal to the user's skin in contact with the target treatment handle. In other words, the handle processor uses the control parameter information to control the corresponding drive circuit to output a treatment signal to act on the user's skin in contact with the target treatment handle.

[0071] The control method provided in this application embodiment is applied to a medical device, including a main unit, multiple treatment handles, and at least one adapter. Each adapter is connected to the main control board and a first switching power supply in the main unit via a main cable. Each adapter is also connected to at least two branch cables, each branch cable corresponding to a treatment handle, and the adapter is electrically connected to the corresponding treatment handle via the branch cables. The method includes: the main control board generating a control signal based on treatment parameters input by the operator; the main control board determining a target adapter according to the control signal and a preset correspondence; the main control board sending the control signal to the target adapter via the main cable; the target adapter determining a target treatment handle based on handle identification information and sending control parameter information to the target treatment handle via the corresponding branch cable; and the target treatment handle outputting a treatment signal to the user's skin in contact with the target treatment handle according to the control parameter information. The technical solution provided in this application embodiment, since the main control board and the first switching power supply in the main unit are connected to the adapter via the main cable, and each adapter is also connected to at least two branch cables, each branch cable corresponding to a treatment handle, therefore, the number of main cables is at most half the number of treatment handles, thus reducing the number of main cables. On the one hand, the reduction in the number of main cables results in a corresponding reduction in the number of internal wiring harnesses connected to the main cables, simplifying the internal wiring and reducing space occupation. On the other hand, the connection method of main cables and branch cables enables the grouping of treatment handpieces and cables. Furthermore, while the number of main cables is reduced, the length of branch cables is effectively shortened, which can significantly reduce tangling between cables, reduce friction and interference, improve user experience, and extend cable life.

[0072] Optionally, in one specific embodiment of this application, the main unit of the medical device device of this application embodiment may further include: a functional safety board. The power supply of the first switching power supply is transmitted to the main cable after passing through the functional safety board, and the functional safety board is provided with an ADC circuit and a safety processor. Correspondingly, the control method of this application embodiment may further include: The safety processor collects the power supply parameters provided by the first switching power supply to the adapter through the ADC circuit, determines whether a first power failure has occurred based on the power supply parameters collected by the ADC circuit, and cuts off the power supply to the main cable when a first power failure occurs.

[0073] In this specific embodiment, the functional safety board can collect the power signal / power supply parameters flowing from the first switching power supply to the adapter in real time through the ADC circuit. Since the functional safety board directly collects the signal on the power line, even if there is a hardware circuit failure between the host and the treatment handpiece, a DAC chip failure on the main control board, or a crash in the main control program of the main control board, the functional safety board can promptly identify power faults such as overvoltage, undervoltage, and overcurrent, and then cut off the power supply to the main cable to block the spread of faults from the hardware link.

[0074] Optionally, in one specific embodiment of this application, the control method of this application may further include: The functional safety board obtains control parameter information from the main control board; The safety processor determines whether a second power failure has occurred based on the power supply and control parameters collected by the ADC circuit, and cuts off the power supply to the main cable when a second power failure occurs.

[0075] This specific implementation can accurately identify power faults when the actual output of the treatment handpiece differs from the expected output, facilitating timely troubleshooting and preventing harm to the user.

[0076] Optionally, in one specific embodiment of this application, the medical device is a laser liposuction device, and the control parameters of each treatment handpiece connected to the same adapter are the same. The control method of this application embodiment may further include: When entering the treatment parameter input interface of any adapter, a prompt message is displayed indicating the placement position of the treatment handle connected to that adapter.

[0077] Specifically, the operator can access the treatment parameter input interface of each adapter by sliding or clicking on the interface selection controls. After entering the treatment parameter input interface of any adapter, the interface displays placement prompts for the treatment handles connected to that adapter, guiding the operator to place each treatment handle in the corresponding position. In practical applications, the placement prompts are determined based on the thickness and shape of the fat layer at the body location, as well as the treatment objective. For example, the fat thickness in the face, neck, periocular area, and jawline is relatively shallow, and the usual treatment objective is superficial fat reduction and tightening. Clinically, treatment handles for the face, neck, periocular area, and jawline can be connected to the same adapter, using the same control parameters. When entering the corresponding treatment parameter input interface, the operator is prompted to place the treatment handles on the face, neck, periocular area, and jawline. The human body has thick fat deposits in areas such as the waist, abdomen, buttocks, and inner thighs, and the treatment area is relatively large. The usual treatment goal is deep fat reduction. Therefore, in clinical practice, the treatment handles for treating the waist, abdomen, buttocks, and inner thighs can be connected to the same adapter and treated using the same control parameters. When entering the corresponding treatment parameter input interface, the operator is prompted to place the treatment handle on the waist, abdomen, buttocks, or inner thighs.

[0078] For ease of intuitive understanding, an example will be provided here using the treatment parameter input interface of a laser liposuction device developed by the applicant using the technical solution of this application. See [link to relevant documentation]. Figure 6 The diagram shown is a schematic of a treatment parameter input interface provided in an embodiment of this application. In this treatment parameter input interface, interface selection controls (corresponding to the controls in the diagram of adapters a, B, C, and D at the bottom of the interface) are provided at the bottom. Users can click on the corresponding interface selection control to enter the corresponding treatment parameter input interface, and the corresponding placement prompt information (not shown in the diagram) will be displayed. For example... Figure 6 The image shows the treatment parameter input interface for adapter B. In this interface, users can set parameters such as laser wavelength, pulse width, energy level, and treatment duration. The interface also includes a handle selection sub-control; clicking the corresponding sub-control illuminates it, indicating that the corresponding treatment handle has been selected. Figure 6 In the interface shown, the operator simultaneously sets the control parameters for each treatment handle connected to adapter B. After setting the treatment parameters on one treatment parameter input interface, the operator can access other treatment parameter input interfaces by clicking the interface selection control below to set the corresponding treatment parameters.

[0079] In this specific embodiment, all treatment handles connected to the same adapter use the same control parameters. The operator can set the control parameters for multiple treatment handles with a single setup, reducing the complexity of operation. Furthermore, displaying placement prompts reminds the operator to place the treatment handles correctly, ensuring treatment effectiveness and user safety.

[0080] Optionally, in one specific embodiment of this application, step S530 may include: When the operator completes the input of treatment parameters, the main control board sends the corresponding control parameter information to the target adapter via the main cable; After the operator clicks the start control, the main control board continuously sends the corresponding handle identification information to the target adapter via the main cable during the set treatment time period.

[0081] Specifically, in practical applications, the system can confirm that the operator has completed the input of treatment parameters after a preset time has elapsed since the operator stopped inputting them, or when the operator clicks the preparation control on the treatment parameter input interface. At this point, the main control board determines the target adapter based on the control signals and the preset correspondence, and then sends the corresponding control parameter information to the corresponding target adapter via the main cable. The number of target adapters can be one or more, depending on the user's treatment needs.

[0082] Furthermore, after the operator clicks the start control, the main control board continuously sends the corresponding handle identification information to the target adapter via the main cable within the set treatment time period. It is obvious that when multiple target adapters exist, the treatment time for the treatment handles on each adapter board is the same, for example, 20 minutes, 30 minutes, etc. Continuing with... Figure 6 Taking the interface shown as an example, after all treatment parameters are set, the operator clicks the "Start" control on any interface, and the main control panel will start the treatment within the set time period. Figure 6 Within 20 minutes, the corresponding handle identification information will be continuously sent to the target adapter via the main cable.

[0083] Accordingly, step S540 may include: The target adapter identifies the target treatment handle based on the handle identification information and continuously sends control parameter information to the target treatment handle through the corresponding branch cable during the time period when the handle identification information is received.

[0084] Specifically, during the time period when the target adapter receives the handle identification information, it continuously sends control parameter information to the target treatment handle through the corresponding branch cable, so that the target treatment handle can output a treatment signal to the user's skin in contact with the target treatment handle according to the control parameter information.

[0085] In this specific implementation, after the operator clicks the start control, the main control board continuously sends the corresponding handle identification information to the target adapter via the main cable during the set treatment time period. During the time period after receiving the handle identification information, the target adapter continuously sends control parameter information to the target treatment handle via the corresponding branch cable, enabling the target treatment handle to output a treatment signal to the user's skin in contact with it according to the control parameter information. Because this specific implementation uses the main control board as the central scheduling unit, enabling the handle identification information within the set treatment time period and controlling the treatment signal output of each treatment handle, synchronous output from each treatment handle is ensured. Furthermore, because this specific implementation sends the control parameter information and handle identification information separately, when the operator completes the treatment parameter input, the control parameter information is first sent to the corresponding target adapter, reducing the bandwidth required for the main control board to subsequently send the handle identification information and ensuring the timeliness of each treatment handle's response.
