[0020] In order to solve the problem that the existing technology cannot accurately control the intensity and irradiation time of light according to the treatment needs of the lesion during actual use, too short irradiation time may lead to poor treatment effect, and too long irradiation time may cause side effects, please refer to Figures 1-9, this embodiment provides the following technical solutions: A short-wave ultraviolet treatment device for gastric diseases includes a mounting platform 1 and an ultraviolet light generator 2. The ultraviolet light generator 2 is mounted on the mounting platform 1. A protective plate 4 is provided on the ultraviolet light generator 2 to prevent the ultraviolet light generated by the ultraviolet light generator 2 from causing harm to patients and medical staff. A connecting socket 8 is provided on the ultraviolet light generator 2, which is connected to an optical fiber 10. A control host 3 is provided on one side of the ultraviolet light generator 2, which is connected to the ultraviolet light generator 2 and a connecting line 11. The optical fiber 10 and the connecting line 11 are both passed through an ultraviolet shielding tube 9, which is arranged in a hose 6, which is clamped in a clamping assembly 5, which is arranged on the side of the mounting platform 1. A hard tube 12 is provided at the end of the hose 6, and a treatment assembly 7 is provided at the end of the hard tube 12.

[0021] The UV generator 2 is used to generate shortwave ultraviolet light, the UV lamp 72 is used to receive and transmit shortwave ultraviolet light, and a control host 3 is used to control the operation of the UV generator 2, UV lamp 72, and image acquisition module 73. The UV light is introduced through an optical fiber 10. Because the optical fiber 10 is small, extendable, and bendable, the control host 3 controls whether the light is irradiated or not. The protective plate 4 is used to protect patients and medical staff from harmful ultraviolet light. It can provide shortwave ultraviolet light of a specific wavelength and can precisely control the light intensity and exposure time, thereby improving the treatment effect and reducing side effects. In addition, it can be easily disinfected and cleaned, thus providing a safe, effective, and convenient treatment method for gastric diseases.

[0022] The treatment component 7 includes a treatment end 71, an ultraviolet lamp 72, an image acquisition module 73, a groove 74, a drive component 75, a support plate 76, a connecting component 77 and a mounting component 78. The ultraviolet lamp 72 and the image acquisition module 73 are respectively provided on the treatment end 71. A filter 79 is provided at the light outlet of the ultraviolet lamp 72. The function of the filter 79 is to filter out unnecessary wavelengths to ensure that only ultraviolet light in a specific wavelength band can pass through. The ultraviolet lamp 72 is connected to the ultraviolet light generator 2 through an optical fiber 10, and the image acquisition module 73 is connected to the control host 3 through a connecting line 11. The treatment end 71 is installed on the mounting component 78. One end of the mounting component 78 is movably installed in the groove 74. The groove 74 is set on the inner wall of the hard tube 12. The other end of the mounting component 78 is installed on the connecting component 77. The connecting component 77 is connected to the driving component 75. One end of the driving component 75 is installed at the bottom of the mounting component 78, and the other end is set on the support plate 76. The support plate 76 is fixed on the inner wall of the hard tube 12.

[0023] The image acquisition module 73 includes: an endoscopic camera, used to capture images of the diseased area of ​​the stomach; An image processing unit, used to pre-process the stomach image captured by the endoscope camera and automatically segment suspicious lesion areas; The image analysis unit is used to analyze the segmented suspicious lesion area and determine the ultraviolet intensity and irradiation time required for ultraviolet treatment.

[0024] Through lesion area analysis, the optimal intensity and irradiation time can be customized based on the lesion depth and size of the gastric lesion area, which significantly improves the accuracy of treatment. Accurate parameter setting reduces the possibility of over-irradiation. By avoiding healthy areas, the analysis ensures that the treatment is limited to suspicious lesions and maximizes the protection of surrounding normal tissues. The image acquisition module 73 monitors lesion changes in real time during treatment and dynamically adjusts the intensity and irradiation time accordingly, which can effectively eliminate inflammation and promote mucosal repair. By precisely controlling the intensity and irradiation time of light, the treatment effect and safety can be significantly improved, ensuring that the lesion tissue can absorb sufficient light energy and effectively destroy the lesion cells, while avoiding treatment failure caused by insufficient dose. By precisely controlling the parameters, excessive irradiation can be prevented from damaging the healthy gastric mucosa, reducing the risk of bleeding, ulcer worsening or inflammation, protecting the surrounding normal tissues, minimizing systemic side effects such as photosensitivity reactions, and improving patient tolerance. The lighting plan is adjusted according to the size, depth and characteristics of the lesion to enhance targeting and accuracy, thereby improving the overall treatment success rate.

[0025] It is used to pre-process the stomach images collected by the endoscope camera and automatically segment the suspicious lesion area, including the following steps: grayscale preprocessing is performed on the image of the gastric lesion area, and median filtering is used to reduce noise to obtain a preprocessed gastric image to be analyzed; Histogram equalization is used to enhance the tissue texture contrast in the pre-processed gastric image, highlighting the blood vessels and lesion boundaries in the gastric lesion area; this can more quickly and clearly grasp the location of the lesion area. The SLIC algorithm is used to segment the pre-processed stomach image into several module area sub-images with uniform size and similar pixels. Each module area sub-image is a 30x30 super-pixel rectangular block. The pixel with the smallest gradient in the super-pixel rectangular block is selected in a 3x3 neighborhood as the center point of each module area sub-image; after setting the center point, the interference of factors such as image edges can be avoided. Connect the center points of any two adjacent module area sub-images to form an updated module area sub-image sample to be analyzed; Feature extraction is performed on each sub-image sample of the module area to be analyzed, and color features and texture features are extracted respectively. The extracted color features and texture features are input into the trained network model for training and recognition to obtain the target lesion area and lesion category; color features include the depth of color and the degree of color change.

[0026] The trained network model pre-stores the lesion categories of the pathological images and reference lesion image samples, as well as healthy reference image samples, and stores the matching relationship between the lesion categories of the pathological images and the reference lesion image samples; The color features and texture features of each sub-image sample of the module area to be analyzed are compared with the reference lesion image sample and the healthy reference image sample, and the similarity value and structural similarity index are calculated; The similarity formula between the color features in each sub-image sample of the module area to be analyzed and the reference lesion image sample and the healthy reference image sample is as follows: in, is the similarity value between the color feature vectors of the sub-image sample of the module area to be analyzed and the reference lesion image sample, represents the similarity value between the color feature vectors of the sub-image sample of the module area 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 area 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, and n represents the dimension of the feature vector. For example, in the RGB color space, each pixel is represented by 3 components, so the dimension n of the feature vector is 3. The dimensions of other color spaces are determined according to actual conditions. i represents the i-th component of the eigenvector x; y i represents the i-th component of the eigenvector y; z i represents the i-th component of the eigenvector z; The formula for the structural similarity index between the texture features in each sub-image sample of the module area to be analyzed and the reference lesion image sample and the healthy reference image sample is as follows: in, Represents the structural similarity index between the texture features in the sub-image sample of the module area to be analyzed and the reference lesion image sample, represents the structural similarity index between the sub-image sample of the module area to be analyzed and the healthy reference image sample, m represents the set of pixel values ​​in the sub-image sample of the module area 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 in the sub-image sample of the module area to be analyzed, represents the mean value of pixels in the reference lesion image sample, represents the mean value of pixels in the healthy reference image sample, represents the covariance of the pixel values ​​corresponding to the sub-image samples of the module area to be analyzed and the reference lesion image samples, Represents the covariance of the pixel values ​​corresponding to the sub-image sample of the module area to be analyzed and the healthy reference image sample, and 、 and It is a constant used to avoid the situation where the denominator is 0. The constant can be the same or different.

[0027] When the similarity value and structural similarity index of the color features and texture features in each sub-image sample of the module area to be analyzed and the reference lesion image sample are higher than the preset similarity threshold and the preset structural similarity index threshold, the area where the sub-image sample of the current analysis module area is located is judged to be the target lesion sub-area. Based on each target lesion sub-region, the corresponding lesion category is obtained; all target lesion sub-regions and corresponding lesion categories are counted to obtain the target lesion region and lesion category, and the target lesion region is defined as a suspicious lesion region.

[0028] The principle and effect of the above technical solution are as follows: by processing and analyzing the collected stomach images, the SLIC algorithm is used to segment and pre-process the stomach images, determine the center of each pixel in the image, and re-form sub-image samples of the module area to be analyzed based on the lines connecting the pixel centers. This can avoid interference from factors such as image edges. By extracting features from the sub-image samples of the module area to be analyzed, the color features and texture features are extracted and further input into the trained network model. The target lesion sub-region and its corresponding lesion category are analyzed and compared with the lesion categories and reference lesion image samples of pre-stored pathological images, as well as healthy reference image samples. Based on similarity comparison, the target lesion sub-region and its corresponding lesion category are determined. The above technical solution can intelligently and quickly identify lesion areas and lesion types from collected images, solving the problems of subjectivity and low efficiency of manual judgment and improving the accuracy of judgment. Correctly selecting the target lesion sub-region and its corresponding lesion category is crucial for determining the UV intensity and irradiation time required for subsequent UV treatment.

[0029] The driving assembly 75 includes a mounting plate 751 , a worm 752 and a motor 753 . The mounting plate 751 is fixed on both sides of the support plate 76 . The worm 753 is rotatably mounted on the mounting plate 751 . One end of the worm 753 passes through the mounting plate 751 and is connected to the motor 753 .

[0030] The connecting assembly 77 includes a worm gear 771, a connecting shaft 772, a first bevel gear 773, a second bevel gear 774, a fixing plate 775 and a rotating shaft 776. The worm gear 771 is rotatably mounted on the support plate 76 via the connecting shaft 772. The connecting shaft 772 is a hollow structure, in which the optical fiber 10 and the connecting line 11 pass. The top of the connecting shaft 772 passes through the mounting assembly 78 and extends to the bottom of the treatment end 71 without contacting the treatment end 71. The first bevel gear 773 is fixed on the connecting shaft 772. The second bevel gear 774 is engaged on both sides of the first bevel gear 773. The second bevel gear 774 is fixed on the rotating shaft 776. The rotating shaft 776 passes through the fixing plate 775 and is rotatably mounted on the mounting assembly 78. The fixing plate 775 is fixed to the bottom of the treatment end 71. The second bevel gear 774 is a half gear. When one of the second bevel gears 774 is a half gear, When 74 is engaged with the first bevel gear 773, the other second bevel gear 774 is not engaged with the first bevel gear 773. Therefore, when the first bevel gear 773 rotates, it drives the two second bevel gears 774 to rotate forward and reverse respectively, thereby driving the treatment end 71 to swing up and down along the rotation axis 776. The motor 753 is a forward and reverse motor, which can enable the worm 753 to drive the worm gear 752 to rotate forward and reverse, thereby driving the connecting component 78 to rotate along the groove 74. At the same time, the rotation of the worm gear 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 causing the rotation axis 776 to swing back and forth along the mounting component 78, so that the ultraviolet lamp tube 72 and the image acquisition module 73 can be adjusted to different angles, thereby realizing image acquisition and treatment of the gastric lesion area at different angles, thereby ensuring the therapeutic effect of gastric diseases.

[0031] The mounting assembly 78 includes a connecting plate 781, a movable block 782 and a mounting piece 783. A movable block 782 is fixed on the top of the connecting plate 781, and the movable block 782 is movably installed in the groove 74. Mounting pieces 783 are installed at both ends of the connecting plate 781 close to the treatment end 71. The rotating shaft 776 is rotatably installed in the mounting piece 783. The connecting shaft 772 is a hollow structure, which is convenient for passing the optical fiber 10 and the connecting line 11, so that the optical fiber 10 and the connecting line 11 can smoothly connect with the ultraviolet lamp tube 72 and the image acquisition module 73. The movable block 782 is movably installed in the groove 74, so that the connecting plate 781 can rotate along the groove 74. At the same time, the second bevel gear 774 is driven to rotate by the rotation of the first bevel gear 773, so that the rotating shaft 776 can drive the treatment end 71 to swing up and down, thereby achieving the purpose of adjusting the angle of the ultraviolet lamp tube 72 and the image acquisition module 73.

[0032] A field of view adjustment component 710 is provided in the treatment end portion 71. The field of view adjustment component 710 includes a lens 711 with a negative focal length, a lens ring 712, a permanent magnet 713, and an electromagnet 714. Specifically, the lens 711 is a meniscus concave lens, and the concave surface of the lens 711 faces the ultraviolet lamp tube 72 and the image acquisition module 73. The lens 711 is fixedly installed in the lens ring 712. A protrusion is provided on the side wall of the lens ring 712. A spiral groove 715 for the protrusion to slide is provided on the inner side wall of the treatment end portion 71. The permanent magnet 713 is provided on the lens ring 712. The polarity of the electromagnet 714 is opposite to that of the permanent magnet 713. The direction of the current passing through the electromagnet 714 is used to change the polarity of the electromagnet 714. When the polarity of the electromagnet 714 is the same as that of the permanent magnet 713, the lens 711 rotates away from the ultraviolet lamp 72 and the image acquisition module 73 due to repulsion. When the polarity of the electromagnet 714 is different from that of the permanent magnet 713, the lens 711 rotates toward the ultraviolet lamp 72 and the image acquisition module 73 due to attraction, thereby changing the field of view of the ultraviolet lamp 72 and the image acquisition module 73 at two positions, thereby increasing the acquisition range of the image acquisition module 73 and the irradiation range of the ultraviolet lamp 72 to meet the needs in different environments.

[0033] The clamping assembly 5 includes a fixed plate 51, a roller 52, a telescopic assembly 53 and a movable plate 54. The fixed plate 51 is fixedly mounted on the mounting platform 1.

Rollers 52 are provided on the inner sides of the movable plate 54 and the fixed plate 51, and the movable plate 54 and the fixed plate 51 are connected by a telescopic assembly 53. By inserting the hose 6 between the rollers 52 and clamping and fixing it through the telescopic assembly 53, medical staff can clamp and fix the hose 6 when treating the patient. At the same time, since the hose 6 is clamped between the rollers 52, when the medical staff pulls the hose 6, the hose 6 can be smoothly pulled under the action of the rollers 52, ensuring that the hose 6 can smoothly extend the treatment assembly 7 into the patient's stomach to treat gastric diseases.

[0035] Working principle: When using the short-wave ultraviolet treatment device for gastric diseases of the present invention, according to Figures 1-8 , including the following steps: Step 1: First, the entire device needs to be disinfected with alcohol. Then, the treatment component 7 is placed into the patient's gastric lesion area. The motor 771 is started so that the driving shaft 776 drives the driving gear 772 and the worm gear 752 to rotate. The driving gear 772 rotates and drives the gear belt 773 to move, which in turn drives the mounting component 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 capture an image of the patient's gastric lesion area. Step 2: Use the median filter algorithm to eliminate the acquisition noise of the gastric lesion area image, align the gastric lesion area images from different perspectives, highlight the blood vessels and lesion boundaries in the gastric lesion area, isolate the gastric lesion area, and automatically segment the suspicious lesion area; Step 3: Analyze the segmented suspicious lesion area to determine the UV intensity and irradiation time required for UV treatment. Then, start the UV generator 2 and use the control host 3 to set the UV intensity and irradiation time. The UV light generated by the UV generator 2 is transmitted to the UV lamp 72 via the optical fiber 10. The optical fiber 10 can ensure the stable transmission of the optical signal without external interference. Step 4: The ultraviolet lamp 72 receives the ultraviolet light transmitted by the optical fiber 10 and emits the ultraviolet light. When the ultraviolet light treats the gastric lesion area, the filter 79 filters out unnecessary wavelengths to ensure that only ultraviolet light of a specific wavelength band can pass through; Step 5: Based on the set ultraviolet intensity and irradiation time, ultraviolet light of a specific wavelength is used to treat the gastric lesion area, and the image acquisition module 73 is used to observe the therapeutic effect of the ultraviolet light during the treatment; Step 6: Based on the observation results of the image acquisition module 73, the motor 753 causes the worm 753 to drive the worm wheel 752 to rotate forward and reverse, thereby driving the connecting component 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 causing the rotating shaft 776 to swing back and forth along the connecting plate 781, driving the treatment end 71 to swing back and forth, adjusting the angle of the ultraviolet lamp 72, and treating different angles of the gastric lesion area.

[0036] In summary, the present invention provides a short-wave ultraviolet treatment device for gastric diseases, wherein the ultraviolet generator 2 is used to generate short-wave ultraviolet light, the ultraviolet lamp 72 is used to receive and transmit short-wave ultraviolet light, and a control host 3 is used to control the operation of the ultraviolet generator 2, the ultraviolet lamp 72 and the image acquisition module 73. The ultraviolet light is introduced by the optical fiber 10. Because the optical fiber 10 is very small and can be extended and bent, the irradiation or non-irradiation is controlled by the control host 3. The protective plate 4 is used to protect patients and medical staff from harmful ultraviolet light. It can provide short-wave ultraviolet light of a specific wavelength and can accurately Control the intensity and irradiation time of light. By precisely controlling the intensity and irradiation time of light, the treatment effect and safety can be significantly improved, ensuring that the diseased tissue can absorb enough light energy to effectively destroy the diseased cells, while avoiding treatment failure caused by insufficient dose. By precisely adjusting the parameters, excessive irradiation can be prevented from damaging the healthy gastric mucosa, reducing the risk of bleeding, ulcer deterioration or inflammation, protecting the surrounding normal tissues, minimizing systemic side effects such as photoallergic reactions, and improving patient tolerance. The light treatment plan can be adjusted according to the size, depth and characteristics of the lesion to enhance targeting and accuracy, thereby improving the overall treatment success rate. In addition, it can also be convenient The worm gear 752 is driven by the motor 753 to rotate forward and reverse, thereby driving the connecting component 78 to rotate along the groove 74. At the same time, the rotation of the worm gear 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 causing the rotating shaft 776 to swing back and forth along the mounting component 78, so that the ultraviolet lamp 72 can be adjusted to different angles, thereby achieving different angles of treatment for the gastric lesion area, and can cover the lesion area in a targeted manner to avoid sticking of healthy tissues. The membrane is over-exposed, which improves the treatment efficiency and reduces the risk of side effects. According to the different lesion depths, the incident angle can be adjusted to control the ultraviolet penetration depth and tissue absorption intensity, while reducing deep tissue damage. Multi-angle flexible irradiation can solve the shadow problem caused by the curvature of the gastric cavity, ensure that the lesion area receives a uniform light dose, and prevent local under-irradiation or repeated irradiation. Unnecessary wavelengths are filtered out by filter 79 to ensure that only ultraviolet light of a specific wavelength can pass. Ultraviolet light of a specific wavelength can directly destroy the DNA / RNA structure of pathogens such as bacteria (such as Helicobacter pylori) and viruses, inhibit their reproduction, and reduce infection factors from the source.
