Description

Technical Field

[0001] The present invention relates to the technical field of digestive organ micro-endoscopes, and specifically to a capsule endoscope, a capsule endoscope detection system and applications of the capsule endoscope. Background Art

[0002] Capsule gastroscopy is an endoscopic examination method that uses a micro camera and wireless transmission technology to send gastric mucosal images to an external receiver in real time. It has the advantages of being non-invasive, painless, anesthetized, and radiation-free, and can improve the patient's compliance and comfort. It is suitable for patients who are afraid of or cannot tolerate traditional gastroscopy, as well as people who need to screen or diagnose gastric diseases.

[0003] Currently, there are two main types of capsule gastroscopy on the market: passive and active. Passive capsule gastroscopy relies on the peristalsis of the gastrointestinal tract and gravity to take random photos in the stomach. It cannot achieve directional observation and repeated observation of specific parts, and is prone to missed inspections and repeated inspections. Active capsule gastroscopy controls the position and direction of the capsule through an extracorporeal magnetic field or other means, and takes precise photos in the stomach. It can achieve comprehensive coverage and focus on various anatomical structures of the stomach, improving the completeness and accuracy of the examination.

[0004] Among active capsule gastroscopy, the magnetically controlled capsule gastroscopy is a capsule endoscopy system that uses an extracorporeal magnetic field to actively control the position and direction of the capsule, thereby achieving a comprehensive observation of the gastric mucosa and can be used for upper gastrointestinal tract examination.

[0005] However, the existing capsule gastroscope mainly adopts imaging mode, which requires the inspector to judge whether there is abnormality or lesion based on the image and make corresponding diagnosis and analysis. This not only requires high-resolution imaging structure, but also requires the inspector to have certain professional knowledge and clinical experience, otherwise it may lead to misdiagnosis or missed diagnosis, affecting the quality and accuracy of the examination. Moreover, due to the large volume of the high-resolution imaging structure, the volume of the capsule gastroscope is relatively large, which not only affects the sensitivity of the capsule gastroscope movement, but also is not conducive to the patient's swallowing and movement in the stomach, which is easy to cause discomfort to the patient and the reaction of the stomach muscles, affecting the comfort and stability of the examination. Summary of the invention

DETAILED DESCRIPTION

[0035] The following is a description of the implementation of the present invention by specific embodiments. The relevant technical personnel can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] The object of the present invention is to provide a capsule mirror, a capsule mirror detection system and an application of the capsule mirror, so as to solve the technical problems that the existing capsule mirror has a large volume and low accuracy of image recognition results using imaging.

[0037] Figure 1 It is a schematic diagram of the capsule mirror based on the micro-spectral sensor of the present invention.

[0038] like Figure 1 As shown, the capsule mirror 31 provided by the present invention includes a capsule shell 1, a broadband light source 2, a spectrum sensor 3, a microcontroller 5, a traction device 6, a wireless communication module 7, and a battery 4.

[0039] The capsule shell 1 has a accommodating cavity, which is used to fix and accommodate the broadband light source 2, the spectral sensor 3, the microcontroller 5, the traction device 6, the wireless communication module 7, and the battery 4. The accommodating cavity can be one or more through-going chambers. The accommodating cavity is integrally formed with the capsule shell 1 and can be one or more of any shapes such as circular, rectangular, irregular, etc.

[0040] There may be one or more broad spectrum light sources 2, preferably broad spectrum LED light sources, a single broad spectrum light source 2 covers an angle of less than 180, and the wavelength range of light emitted by the broad spectrum light source 2 is preferably 230-5000nm. For example, it may be 230nm, 300nm, 390nm, 500nm, 1000nm, 2000nm, 2700nm, 3000nm, 4000nm, 4500nm, 5000nm, etc., which will not be described one by one here.

[0041] The spectral sensor 3 is used to receive the reflected light and / or scattered light emitted by the wide-spectrum light source 2 after passing through the inner wall of the part to be detected. Multiple spectral sensors 3 are arranged in different directions within the coverage range of the light source to receive the reflected light and / or scattered light in multiple directions. Specifically, multiple spectral sensors 3 can be arranged around the wide-spectrum light source 2, or multiple wide-spectrum light sources 2 can be distributed around the capsule shell 1, and then one spectral sensor 3 corresponds to one wide-spectrum light source 2. By arranging the spectral sensors 3 in multiple directions, multi-angle and all-round spectral data are obtained, and the spectral data is output, which improves the coverage and repetition rate of the part illuminated by the light source, so that the required result is highly accurate. The present invention adopts the spectral sensor 3 and the wide-spectrum light source 2, which can cover multiple bands such as visible light, ultraviolet light and near-infrared light, improves the recognition ability and sensitivity of abnormalities or lesions of different types and degrees, and can find problems that are difficult to see with the naked eye.

[0042] Since the present invention adopts a spectral sensor and a wide-spectrum light source, it can identify a wider spectral range and can cover spectral signals of multiple bands, thereby improving the ability to distinguish and identify the spectral characteristics of the gastric mucosa, making the identification more accurate and able to discover some abnormalities or lesions that are difficult to see with the naked eye, thereby improving the sensitivity and accuracy of the examination.

[0043] Since the present invention arranges multiple sensors on the capsule mirror, each sensor has a different detection direction, thereby realizing multi-angle and all-round scanning and detection of the part to be detected, increasing the coverage and repetition rate of the inspection, and also increasing the recognition ability and sensitivity of abnormalities or lesions at different angles and positions, while also accelerating the inspection speed and shortening the inspection time.

[0044] The spectral sensor 3 adopts a simple and compact micro-optical structure, which greatly reduces the volume of the capsule mirror, thereby improving the sensitivity of the capsule mirror movement. The capsule mirror provided by the present invention removes the imaging structure, does not need to focus or adjust the distance, and does not need to consider the imaging resolution, reduces the complexity and volume of the structure, thereby improving the accuracy of the result recognition and reducing the overall volume of the capsule mirror.

[0045] The spectrum sensors 3 are distributed on all the circumferences of the capsule mirror, or on the circumferences of both ends. The receiving surface of the spectrum sensor 3 for reflected light and / or scattered light is provided with a predetermined distance from the inner surface of the accommodating cavity of the capsule shell 1. Optionally, the receiving surface of the spectrum sensor is at a certain distance from the first inner surface 8, which is the surface closest to the spectrum sensor 3 in the accommodating cavity. Preferably, the distance is 2-4 mm to expand the receiving range of reflected light and / or scattered light.

[0046] The above-mentioned spectral sensor 3 includes: a quantum dot filter and a detector. The quantum dot filter is located on the receiving side of the detector. The quantum dot filter is used for filtering light in different bands. The quantum dot filter can be located on the detector or as a separate structure located in front of the detector.

[0047] The spectral sensor 3 is connected to the microcontroller 5, and the microcontroller 5 is connected to the wireless communication module 7. The spectral sensor 3 receives reflected light and / or scattered light, and outputs spectral data to the microcontroller 5. The microcontroller 5 outputs the spectral data to the wireless communication module 7, and the wireless communication module 7 sends the received spectral data to the external receiver 32 via a wireless signal.

[0048] Among them, a permanent magnet is arranged in the traction device 6. Since the permanent magnet is controlled and guided by an external magnetic control device, the capsule shell 1 is driven to move. The position and direction of the capsule shell 1 are changed by the external magnetic control device to obtain spectral data of different parts.

[0049] The battery 4 is electrically connected to the broadband light source 2, the microcontroller 5, the traction device 6, and the wireless communication module 7 and provides power for them.

[0050] It should be noted that the reflected light and / or scattered light after the light emitted by the light source is irradiated to the part to be detected is received by the spectral sensor 3, the light source coverage angle is less than 180 degrees, and the spectral sensor 3 is arranged within the coverage range of the light source, covering the detection range to the maximum extent without dead angles. Therefore, in the specific embodiment of the present invention, the positional relationship between the light source and the spectral sensor 3 must be such that the position of the spectral sensor 3 is set within the coverage range of the light source. For example, on the circular end face, the light source is located in the middle, and the spectral sensor 3 is arranged around the light source. The sensor receives the reflected light and / or scattered light after the light emitted by the light source passes through the inner surface of the part to be detected, so that the spectral data image reflecting the inner surface of the part to be detected can be obtained. Avoid the light source directly irradiating the sensor and causing interference to the sensor. Since the present invention arranges multiple optical structures on the capsule mirror, each structure includes a light source and a sensor, and the projection direction of each structure is different, thereby realizing multi-angle and all-round scanning and detection of the part to be detected, there is no need to repeatedly control the position and direction of the capsule mirror through an in vitro magnetic field or other means, and there is no need to manually search or repeatedly search for lesions, and automatic scanning and detection can be realized, which reduces the requirements for the traction structure and the control device, and improves the efficiency and convenience of the inspection.

[0051] Taking the application of capsule gastroscopy in gastric examination as an example, Figure 2 It is a schematic diagram of the capsule mirror based on the micro-spectral sensor of the present invention moving in the stomach.

[0052] like Figure 2As shown, after the patient swallows the capsule mirror 31, the capsule mirror 31 moves in the stomach with the peristalsis of the gastrointestinal tract and the action of gravity. Alternatively, an external magnetic control device cooperates with the traction device 6 and the microcontroller in the capsule. The magnetic control device controls the movement position of the capsule, and the microcontroller controls the spectral sensor 3 to turn on for detection, thereby controlling the capsule mirror 31 to move in the stomach to perform a global scan of the stomach to avoid omissions.

[0053] The reflected light and / or scattered light after the LED projects light through the inner wall of the part to be detected is received by multiple spectral sensors 3, the spectral signal of the surface of the digestive organ is measured, and the spectral data is sent to the external receiver 32 through the wireless communication module 7. The external receiver 32 processes and analyzes the spectral data, and performs corresponding classification and quantitative analysis.

[0055] like Figure 3 As shown, a capsule mirror detection system 300 provided in an embodiment of the present invention includes: a capsule mirror 31, and an external receiver 32 arranged outside the body, wherein the external receiver 32 includes: a first processing unit 32a and / or a second processing unit 32b.

[0056] The first processing unit 32a is signal-connected to the wireless communication module 7, and is used to obtain the physiological index corresponding to the received spectral data according to the correspondence between the received spectral data and the pre-stored spectral data and the physiological index.

[0057] The second processing unit 32b is signal-connected to the wireless communication module 7, and is used to obtain the biochemical parameters corresponding to the received spectral data according to the correspondence between the received spectral data and the pre-stored spectral data and the biochemical parameters.

[0058] The external receiver 32 further includes a display unit 33. The display unit 33 is electrically connected to the first processing unit 32a and the second processing unit 32b, and is used to display the physiological indexes received from the first processing unit 32a and / or the biochemical parameters received from the second processing unit 32b.

[0059] It should be noted that the physiological indicators are obtained by the following method:

[0060] A spectral analysis method based on machine learning is adopted, by training a spectral classification model, the spectral signals corresponding to abnormalities or lesions of different types and degrees are regarded as different categories, and then the received spectral data is classified using the model, so as to identify whether there is an abnormality or lesion, as well as its type and degree. At the same time, the external receiver 32 can also adopt a method based on spectral quantitative analysis, by establishing a spectral quantitative model, fitting the relationship between the spectral signals corresponding to abnormalities or lesions of different types and degrees and their related biochemical parameters or physiological indicators, and then using the model to quantitatively analyze the received spectral data, so as to obtain the corresponding biochemical parameters or physiological indicators. Values.

[0061] It should be noted that the display unit 33 can be an operation terminal such as a computer or a mobile phone.

[0062] An embodiment of the present invention provides an application based on the capsule mirror as described above, comprising: a capsule shell 1, a broadband light source 2, a spectrum sensor 3, a microcontroller 5, a traction device 6, a wireless communication module 7, and a battery 4.

[0063] The capsule shell 1 has a accommodating cavity, which is used to fix and accommodate the broadband light source 2, the spectral sensor 3, the microcontroller 5, the traction device 6, the wireless communication module 7, and the battery 4. The accommodating cavity can be one or more through-going chambers. The accommodating cavity is integrally formed with the capsule shell 1 and can be one or more of any shapes such as circular, rectangular, irregular, etc.

[0064] There may be one or more broad spectrum light sources 2, preferably broad spectrum LED light sources, and a single broad spectrum light source 2 covers an angle of less than 180 degrees, and the wavelength range of light emitted by the broad spectrum light source 2 is preferably 230-5000 nm. For example, it may be 230 nm, 300 nm, 390 nm, 500 nm, 1000 nm, 2000 nm, 2700 nm, 3000 nm, 4000 nm, 4500 nm, 5000 nm, etc., which will not be described one by one here.

[0065] The spectral sensor 3 is used to receive the reflected light and / or scattered light emitted by the wide-spectrum light source 2 after passing through the inner wall of the part to be detected. Multiple spectral sensors 3 are arranged in different directions within the coverage range of the light source to receive the reflected light and / or scattered light in multiple directions. Specifically, multiple spectral sensors 3 can be arranged around the wide-spectrum light source 2, or multiple wide-spectrum light sources 2 can be distributed around the capsule shell 1, and then one spectral sensor 3 corresponds to one wide-spectrum light source 2. By arranging the spectral sensors 3 in multiple directions, multi-angle and all-round spectral data can be obtained, and the spectral data can be output, thereby improving the coverage and repetition rate of the part illuminated by the light source, so that the required result has high accuracy.

[0066] The present invention adopts a spectral sensor 3 and a wide-spectrum light source 2, which can cover multiple bands such as visible light, ultraviolet light and near-infrared light, thereby improving the recognition ability and sensitivity of abnormalities or lesions of different types and degrees, and can detect problems that are difficult to see with the naked eye.

[0067] Since the present invention adopts a spectral sensor and a wide-spectrum light source, it can identify a wider spectral range and can cover spectral signals of multiple bands, thereby improving the ability to distinguish and identify the spectral characteristics of the gastric mucosa, making the identification more accurate and able to discover some abnormalities or lesions that are difficult to see with the naked eye, thereby improving the sensitivity and accuracy of the examination.

[0068] Since the present invention arranges multiple sensors on the capsule mirror, each sensor has a different detection direction, thereby realizing multi-angle and all-round scanning and detection of the part to be detected, increasing the coverage and repetition rate of the inspection, and also increasing the recognition ability and sensitivity of abnormalities or lesions at different angles and positions, while also accelerating the inspection speed and shortening the inspection time.

[0069] The spectral sensor 3 adopts a simple and compact micro-optical structure, which greatly reduces the volume of the capsule mirror, thereby improving the sensitivity of the capsule mirror movement. The imaging structure is removed, and there is no need to focus or adjust the distance, and there is no need to consider the imaging resolution, which reduces the complexity and volume of the structure, thereby improving the accuracy of the result recognition.

[0070] The spectrum sensors 3 are distributed on all the circumferences of the capsule mirror, or on the circumferences of both ends. The receiving surface of the spectrum sensor 3 for reflected light and / or scattered light is provided with a predetermined distance from the inner surface of the accommodating cavity of the capsule shell 1. Optionally, the receiving surface of the spectrum sensor is at a certain distance from the first inner surface 8, which is the surface closest to the spectrum sensor 3 in the accommodating cavity. Preferably, the distance is 2-4 mm to expand the receiving range of reflected light and / or scattered light.

[0071] The above-mentioned spectral sensor 3 includes: a quantum dot filter and a detector. The quantum dot filter is located on the receiving side of the detector. The quantum dot filter is used for filtering light in different bands. The quantum dot filter can be located on the detector or as a separate structure located in front of the detector.

[0072] The spectral sensor 3 is connected to the microcontroller 5, and the microcontroller 5 is connected to the wireless communication module 7. The spectral sensor 3 receives reflected light and / or scattered light, and outputs spectral data to the microcontroller 5. The microcontroller 5 outputs the spectral data to the wireless communication module 7, and the wireless communication module 7 sends the received spectral data to the external receiver 32 via a wireless signal.

[0073] Among them, a permanent magnet is arranged in the traction device 6. Since the permanent magnet is controlled and guided by an external magnetic control device, the capsule shell 1 is driven to move. The position and direction of the capsule shell 1 are changed by the external magnetic control device to obtain spectral data of different parts.

[0074] The battery 4 is electrically connected to the broadband light source 2, the microcontroller 5, the traction device 6, and the wireless communication module 7 and provides power for them.

[0075] The workflow of the capsule endoscope 31 provided in the embodiment of the present invention in stomach detection includes the following steps:

[0076] S1: The patient swallows the capsule mirror 31 on an empty stomach.

[0077] S2: The capsule endoscope 31 provided by the present invention moves in the stomach with the peristalsis of the gastrointestinal tract and the action of gravity, or the capsule is moved by the cooperation of the external magnetic control device with the traction device 6 and the microcontroller in the capsule endoscope, while the wide-spectrum light source 2 projects light to the surface of the digestive organ, and the multiple spectrum sensors 3 receive the light to measure the spectrum signal on the surface of the digestive organ. At the same time, the traction device 6 is controlled by the external magnetic control device.

[0078] S3: Send the spectral data to the external receiver 32 via the wireless communication module 7 .

[0079] S4: The external receiver 32 processes and analyzes the spectral data, determines whether there are abnormalities or lesions, and performs corresponding classification and quantification. Specifically, the external receiver 32 can adopt a spectral analysis method based on machine learning, by training a spectral classification model, taking spectral signals corresponding to abnormalities or lesions of different types and degrees as different categories, and then using the model to classify the received spectral data, thereby identifying whether there are abnormalities or lesions, as well as their types and degrees. At the same time, the external receiver 32 can also adopt a method based on spectral quantitative analysis, by establishing a spectral quantitative model, fitting the relationship between spectral signals corresponding to abnormalities or lesions of different types and degrees and their related biochemical parameters or physiological indicators, and then using the model to quantify the received spectral data, thereby obtaining the corresponding biochemical parameters or physiological indicators. Values.

[0080] S5: The external receiver 32 displays the processed and analyzed results on the screen and generates corresponding reports or charts as needed.

[0081] S6: The examiner makes a judgment and evaluation based on the results displayed by the external receiver 32, and performs further examination or treatment as needed.

[0082] S7: After the substance stays in the stomach for a certain period of time, it is naturally discharged from the body, and the inspection is finished.

[0083] The capsule endoscope provided by the present invention can be applied in the following scenarios: gastroscopy, colonoscopy, lung, nasopharyngeal, genital endoscopy, etc.

[0084] The capsule mirror provided by the present invention recognizes spectral data rather than images, which not only reduces the size of the capsule mirror, but also makes it more convenient to recognize the generated results, reduces the professional requirements of personnel, and improves the accuracy of result recognition without relying on the resolution of imaging.

[0085] Since the present invention adopts a non-imaging detection method, there is no need to use large components such as cameras, and a simple and compact micro-optical structure is adopted. The optical structure is smaller and the sensor is smaller, so the size of the capsule endoscope is greatly reduced, which not only improves the sensitivity of the capsule endoscope movement, but also facilitates the patient's swallowing and movement in the stomach, and reduces the patient's discomfort and the reaction of the stomach muscles.

[0086] Since the present invention adopts a non-imaging detection method, there is no need to take images, nor to perform image processing and analysis. It only needs to judge whether there are abnormalities or lesions based on spectral data, and perform corresponding classification and quantification. This greatly reduces the requirements for professional knowledge and clinical experience of the inspectors, makes result identification more convenient, and does not need to consider the resolution of the imaging structure, reducing the possibility of misdiagnosis or missed diagnosis, improving the objectivity and reliability of the examination, and improving the accuracy of result identification.

[0087] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
