Abstract
Description
Technical Field
[0001] The present invention relates to an integrated cataract examination and diagnosis instrument based on artificial intelligence technology. Different from conventional cataract examination methods, this method does not rely entirely on doctors' subjective clinical experience. Instead, it combines artificial intelligence technology (abbreviated as AI) under big data, smartphones, and a slit lamp magnifier. By leveraging the initiative of AI doctors in deep learning, its technological upgrade is achieved. The auxiliary role of AI doctors is very obvious. It can quickly detect the types of cortical cataract, nuclear cataract, and posterior subcapsular cataract, and at the same time assist in giving the best comprehensive diagnosis and treatment plan based on artificial intelligence technology. Background Art
[0003] The lens in the human eye is the result of epidermal ectodermal cells differentiating into lens vesicles and then gradually differentiating into lens fibers. These lens fibers gather towards the center to form the lens nucleus. It is like the lens of a camera. When light projects onto the retina, we can see a colorful world. When the lens becomes cloudy, cataracts are formed. Cataracts have a decreased sensitivity to light and generally exhibit symptoms such as glare, monocular diplopia, decreased visual acuity, and polyopia with double vision. The common types of cataracts are mainly divided into three categories. One is cortical cataract, which is also the most common senile cataract; one is nuclear cataract, which is a visual impairment that occurs earlier, progresses slowly, and causes clouding of the lens nucleus; one is posterior subcapsular cataract, which is also the most common cataract ophthalmic disease affecting young individuals, characterized by feathery opacity of the posterior subcapsular cortex of the lens, with clear boundaries but gradually affecting vision.
[0004] Accordingly, in order to embrace the intelligent scenario ecological transformation brought by AI and achieve deep integration with artificial intelligence large models, the present invention application specifically proposes an integrated cataract examination and diagnosis instrument based on artificial intelligence technology, which is also the result of the innovative transmission effect of AI in the field of ophthalmology. The characteristics of the present invention application are to organically combine artificial intelligence technology (AI) and smartphones, integrate the cataract CNP grading standard model, instantaneously upload the captured anterior segment image data of the medical patients to the cloud, and then, according to the internationally popular cataract CNP opacity grading standard, help doctors accurately evaluate the opacity degree of different parts of the patient's lens and obtain constructive diagnostic opinions and comprehensive treatment plans based on big data model algorithms.
[0005] Generally, the international cataract CNP opacity grading standard is as follows: Cortical cataract (C) is divided into six categories, namely: C0: The lens is completely transparent; C1: A small amount of punctate opacity; C2: The range of punctate opacity expands, and a small amount of punctate opacity appears in the pupil area; C3: Wheel-shaped opacity, with opacity exceeding two quadrants; C4: Wheel-shaped opacity, 50% opacity in the pupil area; C5: 90% opacity in the pupil area; Nuclear cataract (N) is divided into four categories, namely: N0: The lens is completely transparent, and the embryonic nucleus is clearly visible; N1: Early opacity; N2: Moderate opacity; N3: Severe opacity; Posterior subcapsular cataract (P) is divided into five categories, namely: P0: The posterior capsule of the lens is completely transparent; P1: Approximately 3% opacity; P2: Approximately 30% opacity; P3: Approximately 50% opacity; P4: Opacity exceeding 50%. Obviously, since the turbidity characteristics of the lens are clearly defined in each CNP grading standard, a big data model for accurately evaluating the severity of cataract in patients is provided for AI doctors.
[0006] The data acquisition head component of the cataract examination instrument is a new type of slit lamp microscope. It is not only an ophthalmic optical instrument, but more importantly, it integrates focusing magnification, zooming and micro-distance measurement in one, and a superluminescent diode SLD of 1050nm is built into the lens. Therefore, it has excellent light penetration, that is, it can turn the turbid vitreous body inside the eye into transparent visible light, helping the AI doctor observe the lesions in various layers and parts of the patient's eye, digitize them, and thus determine the severity of its cataract; at the same time, using the deep learning function of artificial intelligence technology, it can obtain the latest medical trends and literature, manage and control the quality of medical records, facilitate the clinical decision-making of evidence-based medicine, thereby overcoming the arbitrariness of ophthalmologists subjectively, and assist doctors in prescribing constructive and safe treatment opinions and comprehensive treatment plans targeted. Summary of the Invention
[0007] The specific content is as follows: An integrated cataract examination instrument based on artificial intelligence technology, comprising: a slit lamp magnifier, an Android smart phone, a support foot, a handle, a middle support hollow column, a rotating cloud platform, and an operation key platform. The key points are as follows: An integrated cataract examination instrument based on artificial intelligence technology is a cataract examination device integrating an electric push rod, a rotating cloud platform, a slit lamp magnifier, and an Android smart phone. There are three core components of this device: the head component is a slit lamp magnifier, the middle component is an Android smart phone, and the rear component is an electric push rod and a rotating cloud platform device that support its three-dimensional movement. The head component, the middle component, and the rear component together constitute an integrated cataract examination instrument based on artificial intelligence technology; The integrated cataract examination and diagnosis instrument based on artificial intelligence technology has two working modes. One is that it can be operated by an ophthalmologist or optometrist holding the handle. For this purpose, anti-slip grooves are specially engraved on the handle. The other is that it can be fixed on the examination table through the support feet for operation; An operation platform also extends from the middle support hollow cylinder. The operation platform is equipped with an LCD screen, an up and down adjustment knob for the electric pull rod, a power button, a right shift adjustment button, a function button, and a left shift adjustment button. The operating condition information of the position of the cataract examination and diagnosis instrument is displayed on the LCD screen; The Android smartphone is fixed on the mobile phone holder. The mobile phone holder is connected to the mobile phone bracket leg chuck through the chuck slot. The mobile phone bracket leg chuck is then connected to the mobile phone bracket leg. The other end of the mobile phone bracket leg is connected to the rotating cloud platform. When the right shift adjustment button or the left shift adjustment button is pressed, the rotating cloud platform starts to rotate, thereby driving the Android smartphone to rotate; The slit lamp magnifier is a device that combines a slit light source and a microscope. It is installed at the top of the electric push rod through the slit lamp magnifier installation screw holes. Turning the up and down adjustment knob of the electric pull rod can adjust the height of the slit lamp magnifier, and the pitching angle of the slit lamp magnifier can also be manually fine-tuned through the inclination fine-tuning knob; In order to further see clearly the situation where the patient's pupil is covered by cataracts, an additional superluminescent diode SLD point light source with a wavelength of 1050 nm is added to the original slit narrow slit light source of the slit lamp magnifier. The superluminescent diode SLD has the characteristics of high brightness, low phase interference, and excellent light penetration. It is an auxiliary light source between a laser and an ordinary light-emitting diode. However, the wavelength and power density of the superluminescent diode SLD will cause certain damage to the eyes. Because after the high-power density SLD light enters the pupil, it can not only allow the doctor to see clearly the turbidity inside the pupil, but also a large amount of light energy will be concentrated on the patient's retina, thereby causing the temperature of the photoreceptor cell layer of the retina to rise rapidly. The worst outcome is that the photoreceptor cells coagulate, degenerate, and necrosis, resulting in irreversible vision damage, making the lens and cornea turbid. Therefore, in order to eliminate the potential danger brought by the high-energy light emitted by the SLD, the eyes of the examinee only need to be placed 20 centimeters in front of the slit lamp magnifier. In addition, the integrated cataract examination and diagnosis instrument based on artificial intelligence technology also has the function of automatically limiting the irradiation time of the superluminescent diode SLD within 600 seconds; The slit lamp magnifier described above is digital, integrating optics, electronics, and computer technology. The binary digital information it outputs is in units of bits and has functions of image capture, storage, and processing. When working, the Android smartphone itself is connected to the mobile Internet, and the Android smartphone is connected to the slit lamp magnifier through the TYPE-C dual sockets on the slit lamp magnifier. Then, according to the examination data of the slit lamp magnifier and the internationally common criteria for cataract diagnosis, the cataract characteristics can be extracted from the data classification. The internationally common grading standards for cataract CNP turbidity are as follows: Cortical cataract (C) is divided into six categories, namely: C0: The lens is completely transparent; C1: A small amount of punctate opacity; C2: The range of punctate opacity expands, and a small amount of punctate opacity appears in the pupil area; C3: Wheel-shaped opacity, with opacity exceeding two quadrants; C4: Wheel-shaped opacity, with 50% opacity in the pupil area; C5: 90% opacity in the pupil area. Nuclear cataract (N) is divided into four categories, namely: N0: The lens is completely transparent, and the embryonic nucleus is clearly visible; N1: Early opacity; N2: Moderate opacity; N3: Severe opacity. Posterior subcapsular cataract (P) is divided into five categories, namely: P0: The posterior capsule of the lens is completely transparent; P1: Approximately 3% opacity; P2: Approximately 30% opacity; P3: Approximately 50% opacity; P4: More than 50% opacity. Obviously, since the turbidity characteristics of the lens are clearly defined in each CNP grading standard, a big data model for accurately evaluating the severity of patients' cataracts is provided for AI doctors.
[0008] It should be noted that the significance of the internationally common criteria for cataract diagnosis is that it at least greatly reduces the number of training times of the integrated cataract examination instrument based on artificial intelligence technology as an assistant to the "AI doctor", that is, to reach the level of being proficient in seeing patients, and it will not fabricate medical records to meet the needs of patients.
[0009] Furthermore, the support feet, handles, and the middle support hollow cylinder are all formed by injection molding of safe, environmentally friendly, and flame-retardant engineering plastics.
[0010] Furthermore, the rotating cloud platform and the electric push rod are both controlled by a domestic high-performance 32-bit dual-core processor ESP32-S3. This chip is in QFN56 package and uses a low-power supply method, supporting fixed-point, floating-point, DSP, Bluetooth, and WiFi operations.
[0011] Furthermore, after pressing the function key, both the rotating cloud platform and the electric push rod can automatically track the examinee. When the distance of the examinee is too large, the Android smartphone will make a sound to remind the examinee not to move.
[0012] Furthermore, the device is powered by 18650 lithium iron phosphate batteries and complies with YY 9706.102-2021 "Medical Electrical Equipment - Part 1-2: General Requirements for Basic Safety and Essential Performance - Collateral Standard: Electromagnetic Compatibility - Requirements and Tests" issued by the National Medical Products Administration. This standard is equivalent to IEC 60601-1-2:2007, so it will not cause electromagnetic interference to other medical electronic devices.
[0013] Furthermore, to ensure the safety and performance of the device in an electromagnetic environment and lower the market entry threshold, the rotating pan-tilt head and electric push rod on the device are not controlled by a closed-loop permanent magnet brushless micro-motor or servo motor, but are driven by a stepper motor with an amorphous alloy body as the core material. Since the amorphous alloy body has a very low coercivity and high magnetic permeability, and the stepper motor belongs to an open-loop control mechanism, its start, stop, and reverse are rapid, and it has good stability during low-speed operation, thus greatly reducing the complexity of the system and minimizing its external electromagnetic interference.
[0014] Furthermore, using an Android smartphone as the core component of an integrated cataract inspection and diagnosis instrument based on artificial intelligence technology is a cost-effective and good choice. Because the integrated cataract inspection and diagnosis instrument based on artificial intelligence technology essentially obtains inferential content under the real observation of a slit lamp magnifier, rather than a language model based on probability and text splicing, the optimal and most cost-effective system effect can be achieved through the addition of an APP application program.

[0018] The following combines the drawings to illustrate the specific implementation manner of the present invention. It should be noted that for simplicity, all installation screws are omitted in the views. Since the involved stepper motor and electric push rod technologies are relatively mature, their internal structures are not drawn either, and only a brief description is given in the text.
[0019] The integrated cataract examination instrument based on artificial intelligence technology includes: slit lamp magnifier (1), Android smartphone (2), support foot (5-1), handle (5-2), middle support hollow cylinder (5-3), rotating cloud platform (5-4), operation key platform (3), and its key points are: The integrated cataract examination and diagnosis instrument based on artificial intelligence technology is a cataract examination and diagnosis device that uses a pan-tilt with an electric push rod. The core components of this device are three: the head component is a slit lamp magnifier (1), the rear component is an Android smartphone (2), and the pan-tilt and electric push rod (5-5) device that supports the three-dimensional movement of the cataract examination and diagnosis instrument; The integrated cataract examination and diagnosis instrument based on artificial intelligence technology has two working modes. One is that it can be operated by an ophthalmologist or optometrist holding the handle (5-2). For this purpose, anti-slip grooves are specially engraved on the handle (5-2). The other is that it can be fixed and operated on the examination table through the pan-tilt feet (5-1); An operation platform (3) also extends from the middle support hollow cylinder (5-3). The operation platform (3) is equipped with a liquid crystal screen (3-1), an up and down adjustment knob for the electric pull rod (3-2), a power button (3-3), a right shift adjustment button (3-4), a function button (3-5), and a left shift adjustment button (3-6). The operating conditions information of the three-dimensional position of the cataract examination and diagnosis instrument is displayed on the liquid crystal screen (3-1); The Android smartphone (2) is fixed on the mobile phone holder (2-1). The mobile phone holder (2-1) is connected to the mobile phone holder leg chuck (5-4-2) through the holder slot (2-2). The mobile phone holder leg chuck (5-4-2) is then connected to the mobile phone holder leg (5-4-1). The other end of the mobile phone holder leg (5-4-1) is connected to the rotating pan-tilt (5-4). When the right shift adjustment button (3-4) or the left shift adjustment button (3-6) is pressed, the rotating pan-tilt (5-4) starts to rotate, thus driving the Android smartphone (2) to rotate; The slit lamp magnifier (1) is a device that combines a slit light source and a microscope. It is installed at the top of the electric push rod (5-5) through the slit lamp magnifier mounting screw holes (1-5). Turning the up and down adjustment knob for the electric pull rod (3-2) can adjust the height of the slit lamp magnifier (1), and the pitching angle of the slit lamp magnifier (1) can also be manually fine-tuned through the inclination fine-tuning knob (1-4); In order to further see clearly the condition of the patient's pupil covered by cataracts, the slit lamp magnifier (1) is additionally equipped with a superluminescent diode SLD (1-2) point light source with a wavelength of 1050 nm on the basis of the original slit narrow-slit light source. The superluminescent diode SLD (1-2) has the characteristics of high brightness, low phase interference, and excellent light penetration. It is an auxiliary light source between a laser and an ordinary light-emitting diode. However, the wavelength and power density of the superluminescent diode SLD (1-2) will cause certain damage to the eyes. Because after the high-power density SLD light enters the pupil, it can enable the doctor to see clearly the turbidity inside the pupil, and at the same time, a large amount of light energy will be concentrated on the patient's retina, resulting in a rapid increase in the temperature of the photoreceptor cell layer of the retina. The worst outcome is that the photoreceptor cells coagulate, degenerate, and necrosis, causing irreversible vision damage, making the lens and cornea turbid. Therefore, in order to eliminate the potential danger brought by the high-energy light emitted by the SLD, the eyes of the examinee only need to be placed 20 cm in front of the slit lamp magnifier (1). In addition, the integrated cataract examination and diagnosis instrument based on artificial intelligence technology also has the function of automatically limiting the irradiation time of the superluminescent diode SLD (1-2) within 600 seconds; The described slit lamp magnifier (1) is digital, which combines optical, electronic, and computer technologies. The binary digital information it outputs is in units of bits and has functions of image capture, storage, and processing. When working, the Android smartphone itself is connected to the mobile Internet, and the connection of the Android smartphone is connected to the slit lamp magnifier (1) through the TYPE-C double socket (1-3) of the slit lamp magnifier (1). Then, according to the examination and diagnosis data of the slit lamp magnifier (1) and based on the internationally common cataract criteria, the cataract characteristics of the examinee can be extracted from the data classification; The international grading standard for cataract CNP turbidity is as follows: Cortical cataract (C) is divided into six categories, namely: C0: The lens is completely transparent; C1: A small amount of punctate turbidity; C2: The range of punctate turbidity expands, and a small amount of punctate turbidity appears in the pupil area; C3: Wheel-shaped turbidity, with turbidity in more than two quadrants; C4: Wheel-shaped turbidity, 50% turbidity in the pupil area; C5: 90% turbidity in the pupil area; Nuclear cataract (N) is divided into four categories, namely: N0: The lens is completely transparent, and the embryonic nucleus is clearly visible; N1: Early turbidity; N2: Moderate turbidity; N3: Severe turbidity; Posterior subcapsular cataract (P) is divided into five categories, namely: P0: The posterior capsule of the lens is completely transparent; P1: Approximately 3% turbidity; P2: Approximately 30% turbidity; P3: Approximately 50% turbidity; P4: More than 50% turbidity; Obviously, since the turbidity characteristics of the lens are clearly defined in each CNP grading standard, a big data model for accurately evaluating the severity of cataract in patients is provided for AI doctors.
[0020] It should be noted that the significance of the internationally common cataract criterion is that it at least greatly reduces the number of training times of the integrated cataract examination instrument based on artificial intelligence technology as an assistant to the "AI doctor", that is, to reach the level of being proficient in seeing patients, and it will not fabricate medical records to cater to the needs of patients at all.
[0021] Furthermore, the support feet (5-1), the handle (5-2), and the middle support hollow column (5-3) are all formed by injection molding of safe, environmentally friendly, and flame-retardant engineering plastics.
[0022] Furthermore, the rotating cloud platform (5-4) and the electric push rod (5-5) are both controlled by a 32-bit domestic high-performance dual-core processor ESP32-S3. This chip uses a QFN56 package and adopts a low-power supply method, supporting fixed-point, floating-point, DSP, Bluetooth, and WiFi operations.
[0023] Furthermore, after pressing the function key (3-5), the rotating cloud platform (5-4) and the electric push rod (5-5) can automatically track the examinee. When the distance of the examinee is too large, the Android smartphone (2) will make a sound to remind the examinee not to move.
[0024] Furthermore, the device is powered by 18650 type lithium iron phosphate batteries and complies with YY9706.102-2021 "Medical Electrical Equipment - Part 1-2: General Requirements for Basic Safety and Essential Performance - Collateral Standard: Electromagnetic Compatibility - Requirements and Tests" issued by the National Medical Products Administration. This standard is equivalent to IEC60601-1-2:2007, so it will not cause electromagnetic interference to other medical electronic devices.
[0025] Furthermore, in order to ensure the safety and performance of the device in the electromagnetic environment and reduce the market access threshold, the rotating cloud platform (5-4) and the electric push rod (5-5) on the device are not controlled by a closed-loop permanent magnet brushless micro-motor or a servo motor, but are driven by a stepper motor with an amorphous alloy body as the core material. Since the amorphous alloy body has a very low coercivity and high magnetic permeability, and the stepper motor belongs to an open-loop control mechanism, its start, stop, and reverse are rapid, and it has good stability during low-speed operation, thus greatly reducing the complexity of the system and having little electromagnetic interference to the outside.
[0026] Furthermore, using an Android smartphone (2) as the core component of an integrated cataract detection and diagnosis instrument based on artificial intelligence technology is a good choice with low cost. Because the integrated cataract detection and diagnosis instrument based on artificial intelligence technology is essentially the inference content obtained under the real observation of a slit lamp magnifier, rather than a language model based on probability and text splicing, it will certainly not generate facts on the medical records of the examinee with incorrect information. Beneficial effects
[0027] The integrated cataract detection and diagnosis instrument based on artificial intelligence technology proposed by the present invention has the following remarkable beneficial effects: First of all, the present invention application combines artificial intelligence technology, a digital slit lamp magnifier, and an Android smartphone, which can very conveniently provide an accurate cataract number detection scheme and an excellent detection and diagnosis experience for user vision correction for patients.
[0028] Secondly, as an excellent assistant to a virtual ophthalmologist, artificial intelligence technology not only has deep learning ability but also is a tireless "fool" in clinical practice. This "AI doctor" who only works without getting paid and never complains can quickly and accurately identify and analyze the cataract data of the examinee according to the general international grading criteria for cataract CNP turbidity, and can also predict the risk of the examinee developing cataracts in the future by reading the medical record data of a large number of patients, thus adding an intelligent forward-looking element to the ophthalmology industry.
[0029] Thirdly, as a new type of ophthalmic diagnosis technology, artificial intelligence has actually brought high technology to the traditional ophthalmology industry. Because the misdiagnosis rate of the "AI doctor" in ophthalmology is even lower than that of the outstanding graduates of Harvard Medical School. Thus, in the regular optical glasses industry, a corner of artificial intelligence technology innovation has been opened. Obviously, the advent of the integrated cataract detection and diagnosis instrument based on artificial intelligence technology has important practical significance. At least it has brought a real revolution in keeping up with the times to the current ophthalmology field.
[0030] In short, the deep intervention of artificial intelligence technology has greatly alleviated the outpatient pressure on doctors and the queuing trouble of patients. The emergence of artificial intelligence technology is not to replace doctors, the angels in white, but to improve the standardized service quality of hospital departments and avoid fluctuations in the diagnostic quality of ophthalmologists due to outpatient pressure. In addition, with the help of the "AI doctor", ophthalmologists will further put forward humanized treatment opinions in combination with the age and vision conditions of the examinee; they can even provide an analysis report on the development of cataracts for underage patients, predict the future change trend of the patients' vision through artificial intelligence technology, so that the patients can pay attention to eye care and make psychological preparations in advance. Therefore, the application prospect of this device is very broad.
