[0002] Traditional treatments for gastric diseases, such as medication, have long treatment courses and are prone to relapse, while surgical treatments are invasive and require a long recovery period. Existing gastric disease treatment devices based on short-wave ultraviolet radiation have many technical bottlenecks: The treatment parameter settings lack personalization, and it is impossible to accurately adjust parameters such as irradiation intensity and duration according to the patient's disease type, severity and individual physiological differences, which can easily lead to poor treatment effects or side effects; the irradiation direction control is not flexible and accurate enough, making it difficult to adapt to the complex physiological structure of the stomach, and unable to ensure that ultraviolet rays effectively cover the lesion area; the safety protection and real-time monitoring mechanisms during the treatment process are imperfect, and it is impossible to respond to abnormal changes in patients' physiological indicators in a timely manner, posing a major safety hazard. Summary of the Invention

[0003] The purpose of the present invention is to provide a gastric disease therapeutic device based on short-wave ultraviolet irradiation to solve the problems raised in the above background technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a gastric disease therapeutic device based on short-wave ultraviolet irradiation, comprising a treatment control module and a therapeutic device body, wherein the therapeutic device body comprises a main body, a probe end, an ultraviolet emitting end, and an operating handle, and the treatment control module is used to control the therapeutic device body; Wherein, the treatment control module includes: a treatment plan planning unit configured to receive information on the type and severity of a patient's gastric disease, determine a direction and angle combination of the UV light emitting end to be twisted according to a preset treatment logic, and generate a personalized treatment plan; The parameter intelligent adjustment unit is configured to monitor the patient's physiological indicators in real time during treatment, compare the monitoring data with the preset safety threshold, and adjust the intensity and duration of short-wave ultraviolet radiation according to the degree of deviation when the physiological indicators deviate from the normal range; An irradiation direction control unit is configured to control the irradiation angle and direction of the ultraviolet ray emitter according to a personalized treatment plan based on the internal structure image of the stomach and the location information of the lesion transmitted by the gastroscope; An operation instruction processing unit, configured to receive and distribute operation instructions from an operation handle; A treatment status feedback unit is configured to collect treatment data in real time during the treatment process, including the current irradiation intensity, duration, completed irradiation area, and changes in the patient's physiological indicators, and feed it back to the external display terminal in the form of a visual interface; The safety protection control unit is configured to monitor the working status of the ultraviolet light emitting end, the equipment power supply system, the patient status and the equipment connection status in real time. When a device failure, power supply abnormality or an emergency physiological condition of the patient is detected, the safety protection program is immediately triggered, the ultraviolet light emitting power supply is cut off, the treatment operation is stopped, and an alarm is sounded through the sound and light alarm device, and the fault information is pushed to the external display terminal.

[0005] Furthermore, the main body is a retractable structure, which is adaptively retracted according to the personalized treatment plan, specifically: Determine the current irradiation angle and direction of the ultraviolet ray emitter according to the personalized treatment plan, and determine multiple irradiation areas for the patient's stomach according to the current irradiation angle and direction; Obtaining an irradiation area parameter of each irradiation area, and determining the rotation adaptability of the probe end in each irradiation area according to the irradiation area parameter; Determine the maximum distribution length of the main body in each irradiation area according to the rotational adaptability; The optimal extension length of the main body under the personalized treatment plan is calculated based on the maximum distribution length of the main body in each irradiation area: Where H represents the optimal telescopic length of the main body under the personalized treatment plan, It represents the maximum length of the main body, N represents the number of irradiation areas, and i represents the i-th irradiation area. It is expressed as the maximum distribution length of the main body in the ith irradiation area, It is expressed as the overlapping length of the main body in the ith irradiation area and the i-1th irradiation area, ln is expressed as the natural logarithm, Expressed as the distance factor, Expressed as the expansion and contraction plasticity index of the main body; Determining a length adjustment parameter of the main body based on an optimal telescopic length of the main body under a personalized treatment plan; The expansion and contraction limit value of the main body is determined according to the length adjustment parameter, and the expansion and contraction of the main body is controlled based on the expansion and contraction limit value.

[0006] Furthermore, the treatment plan planning unit is configured to receive information on the type and severity of the patient's gastric disease and perform semantic analysis and feature extraction; The disease type and severity information is converted into structured data. At the same time, the lesion location information fed back by the gastroscope is received. The lesion location information in the gastroscope image is converted into three-dimensional spatial coordinate data through a coordinate conversion algorithm. Based on the three-dimensional spatial coordinate data of the lesion location, the spatial geometry algorithm is used to determine the direction and angle combination of the ultraviolet light emitting end to be twisted, completing the irradiation area planning; Acquire structured data and three-dimensional spatial coordinate data, and generate a personalized treatment plan based on the preset treatment logic and the mechanism of action of short-wave ultraviolet rays on different gastric diseases.

[0008] Furthermore, for physiological indicator data within the warning range, the degree of deviation of the data from the threshold is calculated and the degree of deviation is converted into a specific quantitative value; Based on the degree of deviation of physiological indicators, the intensity and duration of short-wave ultraviolet radiation are dynamically adjusted; A corresponding relationship model between the degree of deviation of physiological indicators and the amount of adjustment of irradiation parameters was constructed. When the physiological indicator data was within the warning range, the corresponding irradiation intensity and duration adjustment values ​​were obtained from the corresponding relationship model through linear interpolation based on the quantified value of the deviation degree. For example, if the heart rate deviation is mild, the adjustment strategy will appropriately reduce the irradiation intensity by a certain percentage and shorten the duration of a single irradiation session. If there is a warning of a local temperature increase in the stomach, the irradiation intensity will be reduced first, while the irradiation interval will be extended to prevent further temperature increases. When physiological indicator data is in a dangerous range, the irradiation intensity is quickly reduced according to the maximum safe adjustment amount and the current irradiation operation is suspended; During the process of adjusting the irradiation parameters, the changes in physiological indicator data are monitored in real time and the adjustment effects are evaluated.

DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-7 , the present invention provides the following technical solutions: A gastric disease therapeutic device based on short-wave ultraviolet irradiation includes a therapeutic control module and a therapeutic device body 1. The therapeutic device body 1 includes a main body 2, a probe end 3, an ultraviolet emitting end 4, and an operating handle 5. The therapeutic control module is used to control the therapeutic device body 1. The treatment control module includes: a treatment plan planning unit configured to receive information on the type and severity of a patient's gastric disease, determine a direction and angle combination of the UV light emitting end to be twisted according to a preset treatment logic, and generate a personalized treatment plan; The parameter intelligent adjustment unit is configured to monitor the patient's physiological indicators in real time during treatment, compare the monitoring data with the preset safety threshold, and adjust the intensity and duration of short-wave ultraviolet radiation according to the degree of deviation when the physiological indicators deviate from the normal range; An irradiation direction control unit is configured to control the irradiation angle and direction of the ultraviolet emitting end 4 according to a personalized treatment plan based on the internal structure image of the stomach and the location information of the lesion transmitted by the gastroscope; An operation instruction processing unit configured to receive and distribute operation instructions from the operation handle 5; The treatment status feedback unit is configured to collect treatment data in real time during the treatment process. The treatment data includes the current irradiation intensity, duration, completed irradiation area and changes in the patient's physiological indicators, and is fed back to the external display terminal in the form of a visual interface; The safety protection control unit is configured to monitor the working status of the ultraviolet emission terminal 4, the equipment power supply system, the patient status and the equipment connection status in real time. When a device failure, power supply abnormality or an emergency physiological condition of the patient is detected, the safety protection program is immediately triggered, the ultraviolet emission power supply is cut off, the treatment operation is stopped, and an alarm is sounded through the sound and light alarm device, and the fault information is pushed to the external display terminal.

[0021] In the above embodiment, the treatment control module realizes the precision and intelligence of gastric disease treatment through a multi-unit collaborative architecture. The treatment plan planning unit generates personalized plans based on the disease type and lesion location, and the parameter intelligent adjustment unit monitors the patient's physiological indicators in real time and dynamically adjusts the treatment parameters. The combination of the two significantly improves the safety and effectiveness of treatment. For example, for patients with gastric ulcers, the system can automatically calculate the optimal irradiation intensity and duration based on the ulcer area and depth, and dynamically fine-tune the parameters according to the patient's heart rate and stomach temperature changes during the treatment process to avoid tissue damage that may be caused by traditional fixed parameter treatments. The irradiation direction control unit accurately controls the angle of the ultraviolet emission end through a spatial geometric algorithm to achieve full coverage of irregular lesions, solving the blind spot problem of traditional endoscopic assisted irradiation.

[0022] The treatment plan planning unit is configured to receive information about the type and severity of a patient's gastric disease and perform semantic analysis and feature extraction; The disease type and severity information is converted into structured data. At the same time, the lesion location information fed back by the gastroscope is received. The lesion location information in the gastroscope image is converted into three-dimensional spatial coordinate data through a coordinate conversion algorithm. Based on the three-dimensional spatial coordinate data of the lesion location, the spatial geometry algorithm is used to determine the direction and angle combination of the ultraviolet light emitting end to be twisted, completing the irradiation area planning; Acquire structured data and three-dimensional spatial coordinate data, and generate personalized treatment plans based on the preset treatment logic and the mechanism of action of short-wave ultraviolet rays on different gastric diseases. The personalized treatment plans include irradiation duration, irradiation intensity, number of irradiations and irradiation area planning.

[0023] In the above embodiment, the treatment plan planning unit realizes the precise customization of the treatment plan through semantic analysis and coordinate conversion algorithm. The disease type and severity are converted into structured data, combined with the three-dimensional coordinate reconstruction of the gastroscopic image, so that the system can accurately calculate the torsion angle and irradiation range of the ultraviolet light emitting end. For example, for patients with gastric antral tumors, the system can convert the tumor boundary in the gastroscopic image into three-dimensional spatial coordinates, and plan the optimal irradiation path through the spatial geometry algorithm to ensure that the tumor tissue receives a sufficient dose of ultraviolet radiation while minimizing damage to the surrounding healthy tissues. Compared with traditional empirical treatment, precise planning can improve the treatment effect and significantly reduce the incidence of complications. In addition, the treatment parameter calculation model established by the plan generation subunit comprehensively considers the mechanism of action of short-wave ultraviolet rays on different diseased tissues, and provides the most optimized irradiation plan for each type of gastric disease.

[0024] The parameter intelligent adjustment unit is configured to collect the patient's physiological index data in real time during the treatment process by connecting with the patient's physiological monitoring equipment. The physiological index data include heart rate, blood pressure and local stomach temperature; Based on physiological indicator data, the preset safety threshold is retrieved; The preset safety threshold is set based on individual differences in patient age, gender, and underlying diseases, combined with clinical treatment experience and medical research results; Safety thresholds include normal threshold intervals, warning threshold intervals, and danger threshold intervals for heart rate, blood pressure, and local stomach temperature; Compare the physiological indicator data collected in real time with the preset safety thresholds one by one to determine whether each physiological indicator data is within the normal range, warning range or danger range; For physiological indicator data within the warning range, the degree of deviation of the data from the threshold is calculated and converted into a specific quantitative value; Based on the degree of deviation of physiological indicators, the intensity and duration of short-wave ultraviolet radiation are dynamically adjusted; A corresponding relationship model between the degree of deviation of physiological indicators and the amount of adjustment of irradiation parameters was constructed. When the physiological indicator data was within the warning range, the corresponding irradiation intensity and duration adjustment values ​​were obtained from the corresponding relationship model through linear interpolation based on the quantified value of the deviation degree. For example, if the heart rate deviation is mild, the adjustment strategy will appropriately reduce the irradiation intensity by a certain percentage and shorten the duration of a single irradiation session. If there is a warning of a local temperature increase in the stomach, the irradiation intensity will be reduced first, while the irradiation interval will be extended to prevent further temperature increases. When physiological indicator data is in a dangerous range, the irradiation intensity is quickly reduced according to the maximum safe adjustment amount and the current irradiation operation is suspended; During the process of adjusting the irradiation parameters, the changes in physiological indicator data are monitored in real time and the adjustment effects are evaluated. Each parameter adjustment and the adjustment effect are recorded and transmitted to the treatment status feedback unit.

[0025] In the above embodiment, the intelligent parameter adjustment unit can timely detect potential risks during the treatment process by monitoring multi-dimensional physiological indicators, real-time monitoring of heart rate, blood pressure and local stomach temperature and comparing them with thresholds. For example, when the local stomach temperature exceeds the warning threshold, the system automatically reduces the irradiation intensity and extends the irradiation interval to prevent thermal damage. The establishment of a physiological indicator deviation trend prediction model enables the system to predict risks in advance, such as by analyzing the trend of heart rate variability, adjusting treatment parameters before the patient has a stress reaction, controlling parameter adjustment errors, improving the safety and comfort of treatment, reducing the incidence of adverse reactions during treatment, and shortening the average treatment time of patients.
