[0054] The SLIC algorithm is adopted to segment the pretreated stomach image into a plurality of module area subimages which are uniform in size and contain similar pixels, and each module area subimage is a 30x30 superpixel rectangular block;

[0055] The pixel point with the minimum gradient in the superpixel rectangular block is selected as the center point of each module area subimage in a 3x3 neighborhood; after the center point is set, the interference of factors such as image edges can be avoided,

[0056] The center points of any two adjacent module area subimages are connected to form an updated module area subimage sample for analysis;

[0057] Feature extraction is performed on each module area subimage sample for analysis, color features and texture features are extracted, and the extracted color features and texture features are input into a trained network model for training and recognition to obtain a target lesion area and a lesion category; the color features include the depth of color and the degree of color change.

[0058] In the trained network model, the lesion categories of pathological images and reference lesion image samples and healthy reference image samples are stored in advance, and the matching relationship between the lesion categories of the pathological images and the reference lesion image samples is stored;

[0059] The extracted color features and texture features in each module area subimage sample for analysis are compared with the reference lesion image samples and the healthy reference image samples respectively, and the similarity values and structural similarity indexes are calculated;

[0060] The similarity formula between the color features in each module area subimage sample for analysis and the reference lesion image samples and the healthy reference image samples is as follows:

[0061]

[0062]

[0063] Wherein, is the similarity value between the color feature vectors between the sub-image sample of the module region to be analyzed and the reference lesion image sample, represents the similarity value between the color feature vectors between the sub-image sample of the module region to be analyzed and the healthy reference image sample, that is, the Euclidean distance, x represents the feature vector of the color feature in the sub-image sample of the module region to be analyzed, y represents the feature vector of the color feature in the reference lesion image sample, z represents the feature vector of the color feature in the healthy reference image sample, n represents the dimension of the feature vector, for example, in the RGB color space, each pixel has 3 components, and the dimension n of the feature vector is 3, and the dimensions of other color spaces are determined according to actual conditions; represents the i-th component of the feature vector x; represents the i-th component of the feature vector y; represents the i-th component of the feature vector z;

[0064] The structural similarity index between the texture feature in each sub-image sample of the module region to be analyzed and the reference lesion image sample and the healthy reference image sample is respectively as follows:

[0065]

[0066]

[0067] wherein, represents the structural similarity index between the texture feature in the sub-image sample of the module region to be analyzed and the reference lesion image sample, represents the structural similarity index between the sub-image sample of the module region to be analyzed and the healthy reference image sample, m represents the set of pixel values in the sub-image sample of the module region to be analyzed, n represents the set of pixel values in the reference lesion image sample, and w represents the set of pixel values in the healthy reference image sample; represents the pixel mean value in the sub-image sample of the module region to be analyzed, represents the pixel mean value in the reference lesion image sample, represents the pixel mean value in the healthy reference image sample, represents the covariance of the corresponding pixel values between the sub-image sample of the module region to be analyzed and the reference lesion image sample, represents the covariance of the corresponding pixel values between the sub-image sample of the module region to be analyzed and the healthy reference image sample, and , and are constants, which are used to avoid the case that the denominator is 0, and the constants can be the same or different.

[0068] When the similarity value and the structural similarity index of the color feature and the texture feature in each to-be-analyzed module region sub-image sample and the reference lesion image sample are higher than the preset similarity threshold value and the preset structural similarity index threshold value, it is determined that the region where the current analysis module region sub-image sample is located is a target lesion sub-region,

[0069] Based on each target lesion sub-region, a lesion category corresponding thereto is obtained; all target lesion sub-regions and corresponding lesion categories are counted to obtain a target lesion region and a lesion category, and the target lesion region is defined as a suspicious lesion region.

[0070] The principle and effect of the above technical solution are as follows: through processing and analysis of the collected stomach image, the SLIC algorithm is used to segment the preprocessed stomach image to determine the center of each pixel point in the image, and the to-be-analyzed module region sub-image sample is reformed based on the center line of the pixel point, so that the interference of factors such as image edges can be avoided; through feature extraction on the to-be-analyzed module region sub-image sample, color features and texture features are extracted and further input into a trained network model, and a pre-stored lesion category of a pathological image, a reference lesion image sample, and a healthy reference image sample are analyzed and compared; based on similarity comparison, a target lesion sub-region and a lesion category corresponding thereto are determined. The above technical solution can intelligently and quickly confirm the lesion region and the lesion type from the collected image, solves the problems of subjectivity and low efficiency of manual judgment, improves the accuracy of judgment, and correctly selects a target lesion sub-region and a lesion category corresponding thereto, which has decisive significance for determining the ultraviolet intensity and irradiation time required for subsequent ultraviolet treatment.

[0078] Step one: first, the device as a whole needs to be alcohol-disinfected, then the treatment assembly 7 is sent into the stomach lesion area of the patient, the motor 771 is started to drive the driving shaft 776 to rotate the driving gear 772 and the worm gear 752, the driving gear 772 rotates to drive the gear belt 773 to move, thereby driving the mounting assembly 78 to rotate forward and backward, the angle of the image acquisition module 73 is adjusted, and the image acquisition module 73 is used to acquire the image of the stomach lesion area of the patient;

[0079] Step two: the median filter algorithm is used to eliminate the acquisition noise of the stomach lesion area image, the stomach lesion area images of different angles are aligned, the blood vessels and lesion boundaries of the stomach lesion area are highlighted, and the stomach lesion area is isolated to automatically segment the suspicious lesion area;

[0080] Step three: the suspicious lesion area after segmentation is analyzed to determine the ultraviolet intensity and irradiation time required for ultraviolet treatment, then the ultraviolet light generator 2 is started, the intensity and irradiation time of the ultraviolet light are set by the control host 3, the ultraviolet light generated by the ultraviolet light generator 2 is transmitted to the ultraviolet lamp 72 through the optical fiber 10, and the optical fiber 10 can ensure stable transmission of the optical signal and is not disturbed by the outside world;

[0081] Step four: the ultraviolet light transmitted by the optical fiber 10 is received by the ultraviolet lamp 72, and the ultraviolet light is emitted, when the ultraviolet light treats the stomach lesion area, the filter 79 is used to filter out the unnecessary wavelength, and only the ultraviolet light of a specific wave band can pass through;

[0082] Step five: according to the set ultraviolet intensity and irradiation time, the ultraviolet light of a specific wave band is used to treat the stomach lesion area, and the image acquisition module 73 is used to observe the treatment effect of the ultraviolet light at the same time;

[0083] Step six: according to the observation of the image acquisition module 73, the motor 753 makes the worm 753 drive the worm gear 752 to rotate forward and backward, in turn drives the connecting assembly 78 to rotate along the groove 74, at the same time the worm gear 752 rotates to drive the first bevel gear 773 to rotate, the first bevel gear 773 rotates to drive the second bevel gears 774 on both sides to rotate, in turn makes the rotating shaft 776 swing back and forth along the connecting plate 781, drives the treatment end 71 to swing back and forth, adjusts the angle of the ultraviolet lamp tube 72, and treats the different angles of the stomach lesion area.

[0084] In summary, the short-wave ultraviolet treatment device for stomach diseases of the present application, the ultraviolet light generator 2 is used to generate short-wave ultraviolet light, the ultraviolet lamp tube 72 is used to receive and emit short-wave ultraviolet light, and a control host 3 is used to control the operation of the ultraviolet light generator 2, the ultraviolet lamp tube 72 and the image acquisition module 73. The ultraviolet light is introduced by the optical fiber 10. The optical fiber 10 has a small volume and can be extended and bent. The irradiation or non-irradiation is controlled by the control host 3. The protection plate 4 is used to protect the patient and the medical staff from the harmful ultraviolet light. The short-wave ultraviolet light of a specific wavelength can be provided, and the intensity and irradiation time of the light can be accurately controlled. The treatment effect and safety can be significantly improved by accurately controlling the intensity and irradiation time of the light. The diseased tissue can absorb enough light energy, effectively destroy the diseased cells, and avoid treatment failure caused by insufficient dose. Overexposure to healthy gastric mucosa can be prevented by accurately adjusting the parameters, reducing the risk of bleeding, ulcer exacerbation or inflammation, protecting the surrounding normal tissue, minimizing systemic side effects such as light allergy, improving patient tolerance, adjusting the light exposure scheme according to the size, depth and characteristics of the lesion, enhancing the targeting and accuracy, and thus improving the overall treatment success rate. In addition, disinfection and cleaning can be easily performed. Therefore, a safe, effective and convenient treatment method is provided for treating stomach diseases. The motor 753 is started to drive the worm gear 753 to rotate the worm wheel 752 in the forward and reverse directions, thereby driving the connecting assembly 78 to rotate along the groove 74. At the same time, the rotation of the worm wheel 752 drives the first bevel gear 773 to rotate, and the rotation of the first bevel gear 773 drives the second bevel gears 774 on both sides to rotate, thereby making the rotating shaft 776 swing back and forth along the mounting assembly 78. The ultraviolet lamp tube 72 can adjust different angles, thereby realizing different angle treatment of the stomach lesion area, directional coverage of the lesion site, avoidance of excessive exposure of healthy mucosa, improvement of treatment efficiency and reduction of side effect risk. According to different lesion depths, the incident angle is adjusted to control the penetration depth of the ultraviolet light and the absorption intensity of the tissue, while reducing the damage to the deep tissue. Multi-angle flexible irradiation can solve the shadow problem caused by the curvature of the stomach cavity, ensure that the lesion area receives uniform light dose, prevent local underexposure or repeated irradiation, filter out unnecessary wavelengths through the optical filter 79, ensure that only ultraviolet light of a specific wavelength can pass through, and the specific wavelength ultraviolet light can directly destroy the DNA / RNA structure of pathogens such as bacteria (e.g. Helicobacter pylori) and viruses, inhibit their reproduction, and reduce the infection factors from the source.
