Description

Technical Field

[0001] The present invention relates to the technical field of medical device control, and particularly to a multi-mode dermoscope switching control system and a control method thereof. Background Art

[0002] As a core Class II medical device for clinical diagnosis in dermatology and aesthetic skin detection, based on the principles of optical magnification and multi-mode imaging, the dermoscope provides visual evidence for the diagnosis and differentiation of pigmented skin lesions, vascular lesions, hair diseases, skin tumors, etc. by collecting images of the microscopic structures on the skin surface and under the epidermis. It is widely used in the dermatology departments of medical institutions at all levels, aesthetic medical institutions, and skin health screening scenarios. It is an important tool for accurate assessment and auxiliary diagnosis of skin lesions, and its core performance directly affects the diagnostic accuracy and clinical operation efficiency.

[0003] Existing dermoscope control systems still have obvious technical drawbacks: the device function modes are relatively single, and most can only achieve basic image acquisition, unable to meet the dual requirements of standardized medical photography and multi-scene pathological analysis at the same time; in clinical applications, multiple devices often need to be switched for use, and the process is cumbersome and inefficient. At the same time, the system compatibility is insufficient, and it is difficult to achieve linkage and data intercommunication with professional medical skin microscopy equipment such as in vivo reflectance confocal microscopy. The overall operation process is fragmented and lacks integrated management and control, which is likely to introduce operation errors, not only reducing the clinical work efficiency, but also directly affecting the skin image quality, detection consistency, and the overall operation reliability of the device. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems in the related technologies.

[0005] For this purpose, the object of the present invention is to provide a multi-mode dermoscope switching control system and a control method thereof, which can integrate the in vivo reflectance confocal microscopy mode and the dermoscope mode in the same control system, be compatible with this professional medical skin microscopy equipment, meet the standardization and reliability of clinical photography, cover the professional analysis requirements of multiple scenarios, and solve the problems of single mode and difficult switching of the existing dermoscope system.

[0006] To achieve the above objectives, this invention proposes a multi-mode dermatoscope switching control system and its control method, comprising a main control module, a power supply, an image acquisition module, a display module, a button control module, and a light source module. The main control module is externally connected to host computer software. The main control module is used for logical scheduling and automatic parameter matching of dual working modes. Connected to the host computer software, it sends light source switching commands to the light source module, image control commands to the display module, and adjustment and shooting commands to the image acquisition module, forming a closed-loop control from command issuance to action execution and then to status feedback. The image acquisition module is used to change the magnification, diagonal, and shooting angle, converting the captured optical signals into high-definition digital images, and simultaneously performing image preprocessing, magnification adjustment, and signal distribution functions. The display module provides real-time image preview without delay and supports dynamic adjustment of display parameters, adapting to in vivo reflective confocal microscopy mode and dermoscopy mode. The button control module switches between in vivo reflective confocal microscopy mode and dermoscopy mode, and controls input for other functions, achieving full-process control. The button functions are adaptively matched with the system's working mode. The light source module includes a panoramic plate and a microscopic plate, enabling control of three independent light sources to adapt to different working scenarios. The panoramic plate is equipped with a large-area ring light source, adapting to large field-of-view observation in panoramic mode. The microscopic plate is equipped with multiple polarized and unpolarized light sources, adapting to the in vivo reflective confocal microscopy mode and generating a microscopic field of view in the imaging area of ​​the in vivo reflective confocal microscopy.

[0007] A control method for a multi-mode dermatoscope switching control system includes the following steps: S1. Power-on preparation: Open the host computer software and establish a communication connection with the main control module. S2. Power-on initialization: The control button controls the module to power on, the system is powered on, the microcontroller completes peripheral self-test, circuit self-test, and display module initialization, and the host computer software synchronizes with the system. S3. Initial case creation: Patient information is entered into the host computer software to create a new case, and the case information is synchronized to the local storage by the control unit. S4. Mode Selection: Select the operating mode via the button control module. Branch 1: Select the in-vivo reflective confocal microscope mode. The control unit sends a command to the image acquisition module to lock and match the micro-magnification and field of view of the in-vivo reflective confocal microscope. It also sends a command to the light source module to turn on the light source on the microscope plate. The image acquisition is completed by controlling the button control module. Branch 2: Select dermatoscopy mode, enter the examination type and select the corresponding type, control the image acquisition module to the corresponding magnification through the button control module, select panoramic panel, turn on the ring large-area light source of the micro control unit, configure the image parameters, and complete the image acquisition through the button control module; S5. After acquisition, the image is automatically synchronized to the host computer software, completing the detection process. The system can be shut down by controlling the module with the buttons.

[0008] In addition, the multi-mode dermoscopy switching control system and control method proposed in the above application may also have the following additional technical features: Specifically, the main control module includes a microcontroller unit and an external interface, which can be electrically connected to a power supply, a display module, a button control module, and a light source module.

[0009] Specifically, the button control module includes multiple function control buttons for corresponding power on / off, zoom in / out, photo taking, and switching functions.

[0010] Specifically, the power supply is electrically connected to the main control module to realize DC power supply control for each module.

[0011] Specifically, the light source module may also include a UV plate, on which multiple UV ultraviolet light sources are disposed for skin fungal examination and fluorescence diagnosis.

[0012] Compared with the prior art, the present invention has the following advantages: it can switch between body reflection confocal microscope mode and dermoscopy mode at any time and change the appropriate light source module to meet the multifunctional and multi-environmental needs of clinical imaging, and the switching method is simple and can be realized through the button control module, thereby improving the efficiency of clinical operation and ensuring the reliability of system operation.

[0013] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0014] The above and / or additional aspects and advantages of the present invention will become apparent and readily understood from the following description of the embodiments taken in conjunction with the accompanying drawings, wherein: Figure 1 This is a system block diagram of a multi-mode dermoscopy switching control system and its control method according to the present invention; Figure 2 This is a flowchart illustrating the operation of a multi-mode dermoscopy switching control system and its control method according to the present invention. Detailed Implementation

[0015] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention. Rather, embodiments of the invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0016] The following description, in conjunction with the accompanying drawings, illustrates a multi-mode dermoscopy switching control system and its control method according to an embodiment of the present invention.

[0017] like Figures 1-2 As shown, an embodiment of the present invention provides a multi-mode dermatoscope switching control system and its control method, comprising a main control module, a power supply, an image acquisition module, a display module, a button control module, and a light source module.

[0018] In one embodiment of the present invention, such as Figure 1 As shown, the main control module includes a microcontroller unit and an external interface. The microcontroller unit can be an MCU or a single-chip microcomputer. The external interface includes an interface for the display module, which can be an LCD screen for convenient control and adjustment of parameters and image observation. The button control module can include a power button, a freeze button, a zoom-out button, a zoom-in button, a light source switching button, and a photo button. The light source module includes a panoramic panel, a microplate, and a UV plate. The panoramic panel is an LED pure white light source, and the microplate includes a polarized light source and a non-polarized light source.

[0019] The control module is used for logical scheduling and automatic parameter matching of dual working modes. It connects to the host computer software to send light source switching commands to the light source system module; to send image scaling commands to the display module; and to send magnification adjustment and shooting commands to the integrated camera module, forming a closed-loop control of "command issuance - action execution - status feedback" to avoid loss of control. The power supply is provided with DC power to ensure the stable operation of other hardware modules.

[0020] The image acquisition module can be an integrated mechanism used to change the magnification, focus and shooting control, convert the captured optical signals into high-definition digital images, and perform functions such as image preprocessing, magnification adjustment and signal distribution.

[0021] It should be noted that the control module is a control unit, and the I / O interface realizes functions such as power switch, photo taking, freeze, and light source switching. The detection mode can be switched between in vivo reflective confocal microscope mode and dermoscopy mode, and it can also communicate and control with the host computer software and the integrated machine core.

[0022] In one embodiment of the present invention, such as Figure 1 and Figure 2As shown, the button control module is used for input control of functions such as switching between in vivo reflective confocal microscope mode and dermatoscope mode, power on / off, etc. It converts physical operations into electrical signals and transmits them to the main control module to realize full-process control of the equipment. Moreover, the button functions are adaptively matched with the system working mode, making operation simple.

[0023] The light source system module is used to implement independent light source control units, each adapted to different working scenarios. The panoramic panel integrates a large-area ring light source, namely a ring LED light source, which has a large illumination range and uniform brightness, suitable for large field-of-view observation in panoramic mode, and is used for imaging the overall condition of the skin. The microscopic panel has polarizers on multiple LEDs, providing both polarized and non-polarized light sources, suitable for fine observation in microscopic mode. It also has a UV light source panel for skin fungal examination and fluorescence diagnosis, etc.

[0024] It should be noted that the LED light source uses a high-brightness and uniform light source with a color temperature close to natural light to ensure that the image color restores the true state of the skin. The emission angle is 120 degrees, and the light source integrates polarized and unpolarized light. The polarized light can filter out stray light reflected from the skin surface. The main control module can realize one-click switching between different light sources.

[0025] The light emitted by the LED light source is unpolarized light. When the light emitted by the LED light source is incident on the polarizer, the polarizer only allows the light component parallel to the light transmission axis to pass through, and absorbs or reflects the light component perpendicular to the light transmission axis, thereby converting the unpolarized light into polarized light. To enhance the shooting effect, both the panoramic plate and the microplate adopt a ring design distributed around the perimeter. The polarizers on the microplate are independently installed on the surface of the corresponding LED beads of the light source, keeping the optical axis consistent and avoiding light deviation or loss. A constant current drive circuit design is adopted, with the chip driving the LED series circuit, which provides stable output current and high conversion efficiency.

[0026] like Figure 1 As shown, this application discloses a control method for a multi-mode dermatoscope switching control system, comprising the following steps: S1. Power-on preparation: The operator opens the host computer software and establishes a communication connection with the main control board via USB cable. S2. Power-on initialization: Press the power button on the button control module to power on the system. The main control MCU completes the self-test of peripherals, the self-test of the light source drive circuit, and the initialization of the display module. The LCD screen lights up, and the host computer software synchronizes with the system. S3. Case Creation: Patient information is entered through the host computer software to create a new case, and the main control MCU synchronizes the case information to local storage. S4. Mode Selection: Operators select the working mode via buttons. Branch 1: Select the in-vivo reflective confocal microscope mode. The main control MCU automatically sends instructions to the integrated camera module to lock the fixed magnification and field of view to 10*10mm. At the same time, it sends instructions to the light source drive module to turn on the preset light source. Press the photo button to complete the image acquisition. The acquired image is automatically saved to the host computer. Branch 2: Select dermoscopy mode, then select either skin lesion analysis or hair analysis as the examination type. The operator can use the button controls on the module to zoom in / out to the corresponding magnification. Select the panoramic lens main control MCU to enable the panoramic light source drive, configure the image acquisition parameters of the panoramic mode, and the operator can complete the shooting and editing operations through the button control module; S5. After acquisition, the image is automatically synchronized to the host computer, completing the detection process. The system can be shut down using the power button.
