Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a treatment device for gastric diseases based on shortwave ultraviolet irradiation. Background Technology

[0002] Traditional treatments for stomach diseases, such as medication, suffer from long treatment courses and a high recurrence rate, while surgery is invasive and has a long recovery period. Existing treatment devices for stomach diseases based on short-wave ultraviolet radiation face numerous technical bottlenecks:

[0003] The lack of personalized treatment parameter settings makes it 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 precise enough to adapt to the complex physiological structure of the stomach and cannot ensure that ultraviolet rays effectively cover the lesion area. The safety protection and real-time monitoring mechanisms during the treatment process are not perfect and cannot respond to abnormal changes in the patient's physiological indicators in a timely manner, posing significant safety risks. Summary of the Invention

[0004] The purpose of this invention is to provide a gastric disease treatment device based on short-wave ultraviolet irradiation to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a gastric disease treatment device based on short-wave ultraviolet irradiation, comprising a treatment control module and a treatment device body, wherein the treatment 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 treatment device body;

[0006] The treatment control module includes:

[0007] The treatment plan planning unit is configured to receive information on the type and severity of the patient's gastric disease, determine the direction and angle combination of the ultraviolet emitting end to be twisted according to the preset treatment logic, and generate a personalized treatment plan.

[0008] The parameter intelligent adjustment unit is configured to monitor the patient's physiological indicators in real time during treatment, compare the monitoring data with preset safety thresholds, and adjust the intensity and duration of short-wave ultraviolet irradiation according to the degree of deviation when the physiological indicators deviate from the normal range.

[0009] The irradiation direction control unit is configured to combine the images of the internal structure of the stomach and the location information of the lesions transmitted by the gastroscopy to control the irradiation angle and direction of the ultraviolet emitting end according to the personalized treatment plan.

[0010] An operation instruction processing unit is configured to receive and distribute operation instructions from an operation handle.

[0011] 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.

[0012] The safety protection control unit is configured to monitor the working status of the ultraviolet transmitter, the power supply system of the equipment, the patient status, and the connection status of the equipment in real time. When a fault is detected, an abnormal power supply, or an emergency physiological condition of the patient, the safety protection program is immediately triggered to cut off the ultraviolet emission power supply, stop the treatment operation, issue an alarm through the sound and light alarm device, and push the fault information to the external display terminal.

[0013] Furthermore, the main body is a stretchable structure that adaptively expands and contracts according to the personalized treatment plan, specifically:

[0014] The current irradiation angle and direction of the ultraviolet emitter are determined based on the individualized treatment plan, and multiple irradiation areas for the patient's stomach are determined based on the current irradiation angle and direction.

[0015] Obtain the irradiation area parameters for each irradiation area, and determine the rotation adaptability of the probe end within each irradiation area based on the irradiation area parameters;

[0016] The maximum distribution length of the main body in each irradiation area is determined based on rotational fitness.

[0017] The optimal extension length of the main body under a personalized treatment plan is calculated based on the maximum distribution length of the main body in each irradiation area.

[0018]

[0019] Where H represents the optimal elongation length of the body under a personalized treatment plan. Let N represent the maximum length of the main body, N represent the number of irradiated areas, and i represent the i-th irradiated area. This represents the maximum distribution length of the main body in the i-th irradiation area. Let ln be the overlap length between the i-th and (i-1)-th irradiation regions of the main body, and let ln be the natural logarithm. Represented as distance factor, It is expressed as the stretching-plasticity index of the main body;

[0020] The length adjustment parameters of the main body are determined based on the optimal telescopic length of the main body under the personalized treatment plan.

[0021] The extension and retraction limits of the main body are determined based on the length adjustment parameters, and the extension and retraction of the main body are controlled based on the extension and retraction limits.

[0022] 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;

[0023] The system transforms disease type and severity information into structured data, while simultaneously receiving lesion location information from gastroscopy feedback. A coordinate transformation algorithm is then used to convert the lesion location information in the gastroscopy image into three-dimensional spatial coordinate data.

[0024] Based on the three-dimensional spatial coordinate data of the lesion location, the direction and angle combination that the ultraviolet emitting end needs to be twisted are determined by spatial geometric algorithms to complete the irradiation area planning;

[0025] Structured data and three-dimensional spatial coordinate data are acquired, and based on the preset treatment logic and the mechanism of action of short-wave ultraviolet light on different gastric diseases, a personalized treatment plan is generated. The personalized treatment plan includes irradiation duration, irradiation intensity, number of irradiations, and irradiation area planning.

[0026] Furthermore, the intelligent parameter 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 device. The physiological index data includes heart rate, blood pressure, and local gastric temperature.

[0027] Based on physiological indicator data, retrieve the preset safety threshold;

[0028] 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 findings.

[0029] The safety thresholds include normal threshold ranges, warning threshold ranges, and danger threshold ranges for heart rate, blood pressure, and local gastric temperature.

[0030] The real-time collected physiological indicator data is compared one by one with the preset safety thresholds to determine whether each physiological indicator data is within the normal range, warning range, or dangerous range.

[0031] 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;

[0032] Based on the degree of deviation of physiological indicators, the intensity and duration of shortwave ultraviolet radiation are dynamically adjusted;

[0033] A correlation model is constructed between the degree of deviation of physiological indicators and the adjustment amount of irradiation parameters. When the physiological indicator data is within the warning range, the corresponding adjustment amount of irradiation intensity and duration is obtained from the correlation model by linear interpolation based on the quantified value of the degree of deviation.

[0034] For example, if the heart rate deviation is mild, the irradiation intensity should be appropriately reduced by a certain percentage and the duration of a single irradiation should be shortened according to the adjustment strategy; if an early warning of rising local temperature in the stomach is issued, the irradiation intensity should be reduced first, while the irradiation interval should be extended to prevent the temperature from rising further.

[0035] When physiological indicators are within a dangerous range, the irradiation intensity should be rapidly reduced according to the maximum safe adjustment amount and the current irradiation operation should be suspended.

[0036] During the adjustment of irradiation parameters, changes in physiological indicators are monitored in real time and the adjustment effect is evaluated. Each parameter adjustment and its effect are recorded and transmitted to the treatment status feedback unit.

[0037] Furthermore, a probe end is provided at one end of the main body, an ultraviolet emitting end is provided between the main body and the probe end, the end of the main body away from the probe end is connected to the operating handle, an operating button is provided on the operating handle, a connecting line is provided at the end of the operating handle away from the main body, and a plug is provided at the end of the connecting line away from the operating handle, and the plug is connected to an external display terminal and an external control terminal.

[0038] A camera is installed at the front end of the probe, and light sources are arranged around the camera.

[0039] The main body has an inner tube inside, which connects the probe end, the ultraviolet emitting end, and the operating handle.

[0040] Furthermore, the ultraviolet emitting end includes an equipment area and an irradiation area. The outside of the irradiation area is configured as a light-transmitting layer, and the inside of the irradiation area is equipped with an ultraviolet emitter. An ultraviolet lamp is installed on the side of the ultraviolet emitter near the light-transmitting layer.

[0041] Furthermore, a rotating gear disk is provided inside the equipment area. A sleeve is fixedly connected to one side of the rotating gear disk, and a connecting rod is provided on the outside of the sleeve. The connecting rod is fixedly connected to the ultraviolet emitter. Both the rotating gear disk and the sleeve can be rotatably arranged around the outside of the inner tube. A motor is provided on one side of the tooth grid of the rotating gear disk. A gear is provided on the output shaft of the motor. The gear and the rotating gear disk are connected by gear meshing. The motor is connected to the inner tube through a connecting bracket.

[0042] Furthermore, the probe end contains another ultraviolet emitter for backup and a replacement assembly for replacing it. The replacement assembly includes a replacement frame, a drive block, a drive rod, and a micro motor. The replacement frame is slidably disposed inside the probe end. The drive block is fixed to the rear end of the replacement frame and is threadedly connected to the drive rod. The front end of the replacement frame is provided with at least two placement slots for accommodating the ultraviolet emitter. The placement slots are provided with electromagnetic adsorption components for limiting and unlocking the ultraviolet emitter. A grating disk is provided between the sleeve and the inner tube.

[0043] Furthermore, both sides of the rotating gear disk are provided with annular guide grooves, and positioning guides are provided on the inner wall of the equipment area. There are no fewer than three positioning guides, and the end of the positioning guide away from the inner wall of the equipment area is slidably engaged inside the annular guide groove.

[0044] Compared with the prior art, the beneficial effects of the present invention are:

[0045] 1. The modular design of the main body of the therapeutic device of this invention, combined with the ultraviolet emitting end, significantly improves clinical operability and treatment effect. Combined with the rotating toothed disc drive mechanism, the ultraviolet emitting end can achieve all-round rotation to cover the stomach area. The light-transmitting layer ensures ultraviolet light transmission while blocking infrared radiation, reducing thermal stimulation to the stomach tissue. At the same time, it allows medical staff to observe the irradiation effect in real time, realizing visualized treatment. The treatment control module realizes the precision and intelligence of gastric disease treatment through a multi-unit collaborative architecture. It generates personalized plans based on disease type and lesion location, monitors the patient's physiological indicators in real time, and dynamically adjusts treatment parameters. The combination of the two significantly improves the safety and effectiveness of treatment.

[0046] 2. The treatment plan planning unit of this invention achieves precise customization of treatment plans through semantic analysis and coordinate transformation algorithms. It transforms disease type and severity into structured data and combines it with the three-dimensional coordinate reconstruction of gastroscopy images, enabling the system to accurately calculate the torsion angle and irradiation range of the ultraviolet emitting end, plan the optimal irradiation path, ensure that the tissue receives a sufficient dose of ultraviolet irradiation, minimize damage to surrounding healthy tissues, improve treatment effect, and significantly reduce the incidence of complications. The treatment parameter calculation model established by the plan generation subunit comprehensively considers the action mechanism of short-wave ultraviolet light on different diseased tissues, providing the optimal irradiation plan for each type of gastric disease.

[0047] 3. The intelligent parameter adjustment unit of this invention monitors multi-dimensional physiological indicators, including real-time monitoring and threshold comparison of heart rate, blood pressure, and local gastric temperature. This allows for timely detection of potential risks during treatment. When the local gastric 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. For example, by analyzing the trend of heart rate variability, treatment parameters can be adjusted before the patient experiences a stress response, 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 for patients.

Detailed Implementation

[0056] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0057] Please see Figure 1-7 The present invention provides the following technical solutions:

[0058] A gastric disease treatment device based on short-wave ultraviolet irradiation includes a treatment control module and a treatment device body 1. The treatment device body 1 includes a main body 2, a probe end 3, an ultraviolet emitting end 4, and an operating handle 5. The treatment control module is used to control the treatment device body 1.

[0059] The treatment control module includes:

[0060] The treatment plan planning unit is configured to receive information on the type and severity of the patient's gastric disease, determine the direction and angle combination of the ultraviolet emitting end to be twisted according to the preset treatment logic, and generate a personalized treatment plan.

[0061] The parameter intelligent adjustment unit is configured to monitor the patient's physiological indicators in real time during treatment, compare the monitoring data with preset safety thresholds, and adjust the intensity and duration of short-wave ultraviolet irradiation according to the degree of deviation when the physiological indicators deviate from the normal range.

[0062] The irradiation direction control unit is configured to combine the images of the internal structure of the stomach and the location information of the lesions transmitted by the gastroscopy to control the irradiation angle and direction of the ultraviolet emitting end 4 according to the personalized treatment plan.

[0063] The operation instruction processing unit is configured to receive and distribute operation instructions from the operation handle 5;

[0064] 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.

[0065] The safety protection control unit is configured to monitor the working status of the ultraviolet transmitter 4, the equipment power supply system, the patient status, and the equipment connection status in real time. When a device malfunction, power supply abnormality, or emergency physiological condition of the patient is detected, the safety protection program is immediately triggered to cut off the ultraviolet emission power supply, stop the treatment operation, issue an alarm through the sound and light alarm device, and push the fault information to the external display terminal.

[0066] In the above embodiments, the treatment control module achieves precision and intelligence in the treatment of gastric diseases through a multi-unit collaborative architecture. The treatment plan planning unit generates personalized plans based on the disease type and lesion location, while the parameter intelligent adjustment unit monitors the patient's physiological indicators in real time and dynamically adjusts the treatment parameters. The combination of these 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 changes in the patient's heart rate and gastric temperature during treatment, avoiding tissue damage that may be caused by traditional fixed-parameter treatment. The irradiation direction control unit precisely controls the angle of the ultraviolet emission end through a spatial geometric algorithm, achieving comprehensive coverage of irregular lesions and solving the blind spot problem existing in traditional gastroscopy-assisted irradiation.

[0067] The treatment 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;

[0068] The system transforms disease type and severity information into structured data, while simultaneously receiving lesion location information from gastroscopy feedback. A coordinate transformation algorithm is then used to convert the lesion location information in the gastroscopy image into three-dimensional spatial coordinate data.

[0069] Based on the three-dimensional spatial coordinate data of the lesion location, the direction and angle combination that the ultraviolet emitting end needs to be twisted are determined by spatial geometric algorithms to complete the irradiation area planning;

[0070] By acquiring structured data and three-dimensional spatial coordinate data, and based on the preset treatment logic and the mechanism of action of short-wave ultraviolet light on different gastric diseases, a personalized treatment plan is generated. The personalized treatment plan includes irradiation duration, irradiation intensity, number of irradiations, and irradiation area planning.

[0071] In the above embodiments, the treatment plan planning unit achieves precise customization of treatment plans through semantic analysis and coordinate transformation algorithms. By converting disease type and severity into structured data and combining it with the three-dimensional coordinate reconstruction of gastroscopy images, the system can accurately calculate the torsion angle and irradiation range of the ultraviolet (UV) emitter. For example, for patients with antral gastric tumors, the system can convert the tumor boundary in the gastroscopy image into three-dimensional spatial coordinates and plan the optimal irradiation path using spatial geometry algorithms. This ensures that the tumor tissue receives a sufficient dose of UV radiation while minimizing damage to surrounding healthy tissues. Compared to traditional empirical treatment, precise planning improves treatment efficacy and significantly reduces the incidence of complications. Furthermore, the treatment parameter calculation model established by the plan generation subunit comprehensively considers the action mechanism of short-wave UV radiation on different diseased tissues, providing the optimal irradiation plan for each type of gastric disease.

[0072] 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 includes heart rate, blood pressure and local gastric temperature.

[0073] Based on physiological indicator data, retrieve the preset safety threshold;

[0074] 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 findings;

[0075] Safety thresholds include normal threshold ranges, warning threshold ranges, and danger threshold ranges for heart rate, blood pressure, and local gastric temperature;

[0076] The real-time collected physiological indicator data is compared with the preset safety thresholds one by one to determine whether each physiological indicator data is within the normal range, warning range or dangerous range.

[0077] 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;

[0078] Based on the degree of deviation of physiological indicators, the intensity and duration of shortwave ultraviolet radiation are dynamically adjusted;

[0079] A correlation model is constructed between the degree of deviation of physiological indicators and the adjustment amount of irradiation parameters. When the physiological indicator data is within the warning range, the corresponding adjustment amount of irradiation intensity and duration is obtained from the correlation model by linear interpolation based on the quantified value of the degree of deviation.

[0080] For example, if the heart rate deviation is mild, the irradiation intensity should be appropriately reduced by a certain percentage and the duration of a single irradiation should be shortened according to the adjustment strategy; if an early warning of rising local temperature in the stomach is issued, the irradiation intensity should be reduced first, while the irradiation interval should be extended to prevent the temperature from rising further.

[0081] When physiological indicators are within a dangerous range, the irradiation intensity should be rapidly reduced according to the maximum safe adjustment amount and the current irradiation operation should be suspended.

[0082] During the adjustment of irradiation parameters, changes in physiological indicators are monitored in real time and the adjustment effect is evaluated. Each parameter adjustment and its effect are recorded and transmitted to the treatment status feedback unit.

[0083] In the above embodiments, the intelligent parameter adjustment unit monitors multi-dimensional physiological indicators, including real-time monitoring and threshold comparison of heart rate, blood pressure, and local gastric temperature, enabling timely detection of potential risks during treatment. For example, when the local gastric temperature exceeds a 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 allows the system to anticipate risks in advance. For instance, by analyzing heart rate variability trends, treatment parameters can be adjusted before the patient experiences a stress response, controlling parameter adjustment errors, improving treatment safety and comfort, reducing the incidence of adverse reactions during treatment, and shortening the average treatment time for patients.

[0084] One end of the main body 2 is provided with a probe end 3, and an ultraviolet emitting end 4 is provided between the main body 2 and the probe end 3. The end of the main body 2 away from the probe end 3 is connected to the operating handle 5. The operating handle 5 is provided with an operating button. The end of the operating handle 5 away from the main body 2 is provided with a connecting line 6, and the end of the connecting line 6 away from the operating handle 5 is provided with a plug 7. The plug 7 is connected to an external display terminal and an external control terminal. A camera 301 is provided at the front end of the probe end 3, and light sources 302 are arranged around the camera 301. An inner tube 8 is provided inside the main body 2, and the inner tube 8 connects the probe end 3, the ultraviolet emitting end 4, and the operating handle 5.

[0085] The ultraviolet emitting end 4 includes a device area 401 and an irradiation area 402. The outer side of the irradiation area 402 is configured with a light-transmitting layer 403, and the inner side of the irradiation area 402 is configured with an ultraviolet emitter 404. An ultraviolet lamp 410 is configured on the side of the ultraviolet emitter 404 near the light-transmitting layer 403.

[0086] The equipment area 401 is equipped with a rotating gear disk 405. A sleeve 406 is fixedly connected to one side of the rotating gear disk 405. A connecting rod 413 is provided on the outside of the sleeve 406. The connecting rod 413 is fixedly connected to the ultraviolet emitter 404. Both the rotating gear disk 405 and the sleeve 406 can be rotatably arranged around the outside of the inner tube 8. A motor 407 is provided on one side of the tooth grid of the rotating gear disk 405. A gear 409 is provided on the output shaft of the motor 407. The gear 409 is connected to the rotating gear disk 405 through tooth meshing. The motor 407 is connected to the inner tube 8 through a connecting bracket 408.

[0087] Both sides of the rotating gear disk 405 are provided with annular guide grooves 412. The inner wall of the equipment area 401 is provided with positioning guides 411. There are no fewer than three positioning guides 411. The end of the positioning guide 411 away from the inner wall of the equipment area 401 is slidably engaged inside the annular guide groove 412.

[0088] See Figure 6The ultraviolet emitter 404 is plugged into and connected to the connecting bracket 408. A contact point is provided between the ultraviolet emitter 404 and the connecting bracket 408 to facilitate power supply to the ultraviolet emitter 404. Inside the probe end 3, another ultraviolet emitter 404 for backup and a replacement assembly for replacing it are placed. The replacement assembly includes a replacement frame 304, a drive block 305, a drive rod 306, and a micro motor 307. The replacement frame 304 is slidably disposed inside the probe end 3. The drive block 305 is fixed to the rear end of the replacement frame 304 and is threadedly connected to the drive rod 306. After the micro motor 307 is activated, the replacement frame 304 can move towards or away from the ultraviolet emitter 404. The front end of the replacement frame 304 has at least two slots for accommodating the ultraviolet emitter 404. It should be noted that the interface of the replacement frame 304 is polygonal, so that the replacement frame 304 will not rotate during the movement driven by the drive rod 306.

[0089] The placement slot is equipped with an electromagnetic adsorption component for locking and unlocking the ultraviolet emitter 404. During the replacement of the ultraviolet emitter 404, the replacement rack 304 first approaches the ultraviolet emitter 404 to be replaced and moves it into the empty placement slot. The electromagnetic adsorption component in the corresponding placement slot is activated, fixing the ultraviolet emitter 404 in place. Then, the replacement rack 304 moves in the opposite direction to remove the ultraviolet emitter 404. The motor 407 is then started, causing the connecting bracket 408 to rotate to face the spare ultraviolet emitter 404. The above steps are then reversed to install the spare ultraviolet emitter 404 onto the connecting bracket 408. This allows for quick replacement of the ultraviolet emitter 404 in case of malfunction during use, without removing the probe end 3 from the patient, reducing treatment time and patient discomfort. A grating disk is provided between the sleeve 406 and the inner tube 8. The rotation angle of the connecting bracket 408 is determined by the grating disk, so that the connecting bracket 408 and the ultraviolet emitter 404 can be positioned more accurately.

[0090] In the above embodiments, the modular design of the main body 1 of the treatment device, combined with the ultraviolet emitting end 4, significantly improves clinical operability and treatment efficacy. The flexible connection design between the main body 2 and the probe end 3, combined with the rotating gear disk 405 drive mechanism, allows the ultraviolet emitting end 4 to rotate omnidirectionally, covering more than 95% of the stomach area, solving the problem of blind spots in traditional equipment. The light-transmitting layer ensures an ultraviolet transmittance of ≥90% while blocking infrared radiation, reducing thermal stimulation to stomach tissues. The integrated design of the camera and light source allows medical personnel to observe the irradiation effect in real time, achieving visualized treatment.

[0091] In one embodiment, the main body 2 is a stretchable structure that adaptively expands and contracts according to a personalized treatment plan, specifically:

[0092] The current irradiation angle and direction of the ultraviolet emitting end 4 are determined according to the personalized treatment plan, and multiple irradiation areas for the patient's stomach are determined according to the current irradiation angle and direction.

[0093] Obtain the irradiation area parameters for each irradiation area, and determine the rotation adaptability of probe end 3 within each irradiation area based on the irradiation area parameters;

[0094] The maximum distribution length of the main body 2 in each irradiation area is determined based on the rotational fitness.

[0095] The optimal extension length of the main body 2 under the personalized treatment plan is calculated based on the maximum distribution length of the main body 2 in each irradiation area:

[0096]

[0097] Where H represents the optimal stretch length of the primary body 2 under the personalized treatment plan. Let N represent the maximum length of the main body 2, N represent the number of irradiated areas, and i represent the i-th irradiated area. This represents the maximum distribution length of the main body 2 in the i-th irradiation area. Let ln be the overlap length between the i-th and (i-1)-th irradiation regions of the main body 2, and let ln be the natural logarithm. Represented as distance factor, The extensibility index is represented as the plasticity index of the main body 2.

[0098] The length adjustment parameters of the main body 2 are determined based on the optimal telescopic length of the main body 2 under the personalized treatment plan;

[0099] The extension limit value of the main body 2 is determined based on the length adjustment parameter, and the extension and retraction control of the main body 2 is performed based on the extension and retraction limit value.

[0100] In this embodiment, the irradiation area parameter represents the statistical parameter of the irradiated stomach area for each irradiated region;

[0101] In this embodiment, rotational fitness is expressed as the free rotational fitness of the probe in each irradiation area under the influence of the length of the main tube.

[0102] In this embodiment, the maximum distribution length is represented by the maximum insertion length of the probe in each irradiation area;

[0103] In this embodiment, the overlap length is represented as the length of the shared overlap tube body of the main body in the current irradiation area and the next irradiation area;

[0104] In this embodiment, the length adjustment parameter is represented as a limiting parameter for adjusting the length of the main body;

[0105] In this embodiment, the telescopic limit value is represented as a limit value for the maximum telescopic length of the main body.

[0106] The beneficial effects of the above technical solution are as follows: by matching the length of the probe to the rotational adaptation of the irradiation area in the patient's stomach, the optimal extension length of the main body can be calculated. This ensures that the rotation of the probe is not affected, while also avoiding excessive length that may accumulate in the patient's stomach, thus preventing effective ultraviolet irradiation and reducing the therapeutic effect, thereby improving practicality.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
