The execution subject can be the controller of the computer terminal or smart terminal.

[0072] Next, combine Figure 2The control method of the microneedle patch for treating hypertrophic scars of the present application is described in detail, including the following steps:

[0073] Step S1: Acquire a first image containing a hypertrophic scar area and a second image of the hypertrophic scar area with the microneedle patch for treating hypertrophic scar applied thereon.

[0074] Specifically, a first image including a complete hypertrophic scar area can be taken, and when the microneedle patch for treating hypertrophic scar is completely applied to the hypertrophic scar area, a second image including the microneedle patch for treating hypertrophic scar is taken.

[0075] Step S2: Based on the first image, draw a target contour corresponding to the hypertrophic scar area in the second image.

[0076] Specifically, the target contour corresponding to the hypertrophic scar region in the first image can be drawn on the region of the microneedle patch for treating hypertrophic scars in the second image with reference to the hypertrophic scar region in the first image.

[0077] Step S3: Determine all target heating units corresponding to the target contour.

[0078] Specifically, all target heating units within the target contour range may be determined.

[0079] Step S4: using each target heating unit to heat each matched target microneedle.

[0080] Specifically, an infrared light source or an LED can be used to illuminate each target heating unit to heat each target microneedle corresponding to each target heating unit, so that the thermal response material in each target microneedle undergoes physical changes and releases drugs in the hypertrophic scar area, thereby cosmetically modifying the hypertrophic scar.

[0081] It can be seen from the above technical solutions that the control method of the microneedle patch for treating hypertrophic scars provided by the present application can be applied to a controller connected to the microneedle patch for treating hypertrophic scars; the microneedle patch for treating hypertrophic scars includes an infrared heating plate and a microneedle array; the infrared heating plate includes a plurality of heating units, and the microneedle array includes a plurality of microneedles, each microneedle contains a drug wrapped by a thermal responsive material; each heating unit corresponds to each microneedle; based on this, the microneedle patch for treating hypertrophic scars of the present application can integrate the infrared heating plate and the microneedle array to improve the integration level; the present application combines the characteristics of the drug wrapped in the thermal responsive material, controls the drug release by heating, and provides a controllable method for drug release, which increases the controllability and effectiveness of drug release compared to the passive drug release mode of the traditional microneedle patch; and the control method can obtain a first image containing a hypertrophic scar area, and apply a patch on the hypertrophic scar area. The invention relates to a microneedle patch for treating hypertrophic scars, wherein a target contour corresponding to the hypertrophic scar region is drawn in the second image based on the first image; and all target heating units corresponding to the target contour are determined. Based on this, the present invention can determine the corresponding target heating units by drawing the target contour in the second image, and accurately locate the target heating units to be heated according to the specific shape and position of different hypertrophic scar regions. The target heating units are then used to heat the matched target microneedles to dissolve the thermoresponsive material within each target microneedle, thereby releasing the drug encapsulated by the thermoresponsive material within the hypertrophic scar region. Based on this, the present invention releases the drug in the hypertrophic scar region by heating the precisely located target heating units, precisely controlling the dissolution of the thermoresponsive material so that the drug is released only in the target region corresponding to the hypertrophic scar, thereby improving the precision of the drug effect and avoiding normal tissue damage caused by uneven drug release in traditional treatment methods. As can be seen, the present invention can accurately locate and heat the corresponding microneedles according to the specific morphology of different hypertrophic scars, achieving customized drug release shapes, overcoming the problem that the fixed shape drug release of traditional microneedle patches is difficult to adapt to different scars.

[0082] In some embodiments of the present application, the process of step S1, obtaining a first image including a hypertrophic scar area, and obtaining a second image with the hypertrophic scar treatment microneedle patch applied to the hypertrophic scar area, is described in detail. The steps are as follows:

[0083] S10, obtaining a first image of a hypertrophic scar area taken by a smart camera at the same angle, and a second image of the hypertrophic scar area with the microneedle patch for treating hypertrophic scar applied thereon.

[0084] Specifically, when the shooting angle of the smart camera is fixed, a first image of the hypertrophic scar area captured by the smart camera can be obtained, and a second image captured by the smart camera when the microneedle patch for treating hypertrophic scars is completely applied to the hypertrophic scar area can be obtained.

[0085] It can be seen from the above technical solution that this embodiment provides an optional method for obtaining the first image and the second image. Through the above method, the shooting angles of the obtained first image and the second image can be the same, which facilitates the subsequent mapping of the first image and the second image and improves the reliability of the drawn target contour.

[0086] In some embodiments of the present application, step S2, drawing a target contour corresponding to the hypertrophic scar region in the second image based on the first image, is described in detail. The steps are as follows:

[0087] S20: Search for feature points with the same name in the first image and the second image, and align the first image and the second image.

[0088] Specifically, feature extraction algorithms such as the scale-invariant feature transform algorithm SIFT and the accelerated robust feature algorithm SURF can be used to extract features from the first image and the second image respectively, and generate feature vectors corresponding to each key point in the first image and the second image;

[0089] Perform similarity matching on each feature vector of the first image and each feature vector of the second image, and search for feature points with the same name in the first image and the second image;

[0090] The first image and the second image are aligned based on feature points with the same name.

[0091] S21 . Perform scar boundary recognition on the first image, and draw a scar outline in the first image.

[0092] Specifically, the scar range can be marked in the first image based on the grayscale difference characteristics between the scar and normal skin tissue in combination with the threshold segmentation method;

[0093] An edge detection algorithm, a region segmentation algorithm and other algorithms are used to identify the scar boundary of the scar range in the first image, and a scar outline is drawn in the first image.

[0094] S22. Map the scar contour of the first image to the second image.

[0095] Specifically, after the first image and the second image are aligned, a contour detection algorithm may be used to map the scar contour in the first image to the second image.

[0096] It can be seen from the above technical solution that this embodiment provides an optional method for drawing the target contour corresponding to the hypertrophic scar area in the second image based on the first image. Through the above method, the first image and the second image can be aligned using feature points of the same name, and after alignment, the scar contour of the first image is mapped to the second image to achieve the drawing of the target contour in the second image.

[0097] In some embodiments of the present application, step S20, searching for feature points with the same name in the first image and the second image and aligning the first image and the second image, is described in detail. The steps are as follows:

[0098] S200: Obtain feature points of the same name corresponding to the first image and the second image based on skin texture features of the first image and the second image.

[0099] Specifically, the similarity between each feature vector corresponding to the skin texture of the first image and each feature vector corresponding to the skin texture of the second image may be analyzed to identify feature points with the same name.

[0100] S201 : Calculate a geometric transformation relationship between the first image and the second image based on the feature points with the same name, and align the first image and the second image based on the geometric transformation relationship.

[0101] Specifically, the geometric transformation relationship between the first image and the second image can be calculated based on feature points with the same name by combining algorithms such as affine transformation or similarity transformation.

[0102] With reference to the geometric transformation relationship, the first image and the second image are aligned.

[0103] It can be seen from the above technical solution that this embodiment provides an optional method for aligning the first image and the second image based on feature points of the same name. Through the above method, the skin texture features are used as the main reference points to complete the identification of feature points of the same name and image alignment, thereby reducing the amount of feature vector comparison and improving the alignment accuracy.

[0104] In some embodiments of the present application, step S22, mapping the scar contour of the first image to the second image, is described in detail. The steps are as follows:

[0105] S220: Extract coordinate information of the scar outline in the first image.

[0106] Specifically, in the first image, the coordinate axis can be drawn with the key point corresponding to the feature point of the same name as the coordinate origin;

[0107] The coordinate information of each boundary point of the scar contour can be extracted.

[0108] S221. Construct a transformation matrix for mapping the coordinates of the first image to the second image.

[0109] Specifically, a transformation matrix for mapping the coordinates of the first image to the second image may be constructed based on a geometric transformation relationship.

[0110] The transformation matrix can be a non-rigid transformation field, an affine transformation matrix, or a perspective transformation matrix.

[0111] S222: Map the scar contour from the first image to the second image based on the transformation matrix and the coordinate information.

[0112] Specifically, the transformation matrix and the coordinate information of each boundary point may be multiplied to calculate the boundary coordinate information corresponding to the second image;

[0113] In the second image, the key point corresponding to the feature point with the same name is used as the coordinate origin to draw the coordinate axis;

[0114] Based on the respective boundary coordinate information, the object outline may be drawn in the second image.

[0115] It can be seen from the above technical solution that this embodiment provides an optional method for mapping the scar contour of the first image to the second image. Through the above method, the scar contour in the first image can be further represented in the form of coordinates, thereby completing the contour mapping from the first image to the second image.

[0116] In some embodiments of the present application, in order to avoid heating non-target microneedles as much as possible, a light shield can be configured on each heating unit 21. The controller of the present application can be connected to an infrared light source or an LED lamp.

[0117] Each light shielding plate is movable, and whether to shield the corresponding heating unit 21 can be controlled by moving the light shielding plate.

[0118] On this basis, the process of heating each matched target microneedle using each target heating unit in step S4 is described in detail, and the steps are as follows:

[0119] S40 , removing the shielding of the light shielding plate of each target heating unit, and irradiating each target heating unit with an infrared light source to heat each target microneedle matched with each target heating unit.

[0120] Specifically, the shading plate can be moved to remove the shielding of each target heating unit, and the infrared light source can be controlled to irradiate each target heating unit to heat each target microneedle corresponding to each target heating unit.

[0121] It can be seen from the above technical solution that this embodiment provides an optional method of using each target heating unit to heat each matching target microneedle. Through the above method, the shielding plate control can be used to achieve microneedle heating control, avoid heating non-target microneedles, and better avoid damage to normal tissues during the treatment of hypertrophic scars.

[0122] In some embodiments of the present application, the process of irradiating each target heating unit with an infrared light source in step S40 is described in detail, and the steps are as follows:

[0123] S400: Extracting color depth features of the hypertrophic scar region in the first image.

[0124] Specifically, the feature extraction unit may be used to extract the color depth features of the hypertrophic scar region in the first image.

[0125] S401. Generate an irradiation intensity based on the color depth feature, and use the infrared light source to irradiate each target heating unit with the irradiation intensity to adjust the drug release rate of each target microneedle.

[0126] Specifically, a trained illuminance prediction model can be obtained, and the color depth feature can be input into the illuminance prediction model to obtain the illumination intensity output by the illuminance prediction model, wherein the illuminance prediction model is trained with multiple different color depth training features labeled with corresponding training illuminances.

[0127] The irradiation intensity of the infrared light source can be adjusted, and the adjusted infrared light source is used to irradiate each target heating unit to adjust the drug release rate of each target microneedle.

[0128] It can be seen from the above technical solutions that the present application takes into account different scar severity and requires different drug release rates. Therefore, the present application can adjust the irradiation intensity according to the color depth characteristics reflecting the severity of the scar to improve the accuracy of drug release.
