DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the present invention clearer, the fully automatic slit lamp and its intelligent diagnosis method proposed by the present invention are further described in detail in combination with the accompanying drawings and exemplary descriptions. It should be noted that the structure, proportion, size, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they have no technical substantive significance.

[0038] Application Overview In the field of ophthalmic examination, facing technical problems such as the complexity of operation and difficulty in fault diagnosis of slit lamp microscopes, the conventional treatment methods in the industry mainly rely on the professional skills and experience of doctors or operators. For the complexity of operation, doctors usually need to undergo long-term training and practice to master the manual adjustment of various parameters of the slit lamp, such as light source brightness, slit width, observation angle, etc., in order to obtain clear and accurate examination images. However, this manual operation is not only time-consuming and labor-intensive, but also has a steep learning curve for novice doctors, making it difficult to get started quickly, limiting the improvement of inspection efficiency. In addition, when the equipment fails, conventional intelligent diagnosis methods often require operators to carefully observe and inspect the physical structure of the slit lamp, judge possible faulty components from the outside, and then check them one by one. This method is not only time-consuming, but also requires extremely high experience from the operator. It is easy to cause inaccurate fault diagnosis due to lack of experience or negligence, delay the repair and maintenance of the equipment, and affect the normal progress of ophthalmic examinations. At the same time, the data management of traditional slit lamps is also relatively cumbersome. Imaging results and examination data usually need to be manually recorded and stored, which is not conducive to remote sharing and long-term preservation of data, and limits the development of telemedicine and case analysis.

[0039] Example The fully automatic slit lamp in this solution is an ophthalmic examination device that integrates advanced automatic adjustment and fault diagnosis functions. Its core components include the slit lamp device, automatic adjustment device and human-computer interaction device. All parts work together to achieve efficient and accurate operation of the slit lamp and intelligent fault detection.

[0040] In order to achieve a complete technical effect, the present invention has two sets of nested and complementary technical solutions. The first set is a fully automatic slit lamp, including: Please refer to Figure 1 , Figure 2 Slit lamp device The slit lamp device is the main part of the equipment, which is responsible for generating slit light and guiding the light to illuminate the eyes of the examinee to obtain eye image data. It includes a camera element, an imaging adjustment structure 2, a zoom lens structure 3, a slit rotation angle adjustment structure 4, a diffusion adjustment structure 5, a slit width adjustment structure 6, a filter adjustment structure 7, a light spot adjustment structure 8, a curved arm rotation angle adjustment structure 9, a light source structure 10 and other components.

[0041] The camera element converts the light guided by the imaging component into electrical signals, generating clear image data, providing a basis for subsequent image analysis and diagnosis.

[0042] Automatic adjustment device The automatic adjustment device consists of a calculation module and an adjustment module, and is the core of the automatic adjustment of the slit lamp. The calculation module is responsible for receiving the preset working mode input by the examiner through the human-computer interaction device, and calculating the operating parameters of each component of the slit lamp device according to the mode requirements. The adjustment module drives the slit lamp device through gear transmission to accurately adjust the position and state of each component.

[0043] The adjustment module includes multiple motors and a three-axis mobile bracket. Each axis of the three-axis mobile bracket is provided with a motor, which can realize the flexible movement and adjustment of the slit lamp device in three-dimensional space. In addition, each adjustment structure of the slit lamp device, such as the imaging adjustment structure 2, the magnifying mirror structure 3, etc., is provided with a motor in its adjustment part to ensure that the slit lamp can achieve the effect of no manual adjustment in different inspection modes.

[0044] Human-computer interaction device The human-machine interaction device is a bridge for the operator to communicate with the equipment, including a display module 1 and a prompt module. The display module 1 uses a high-resolution display screen, which can clearly display a variety of preset working modes for the examiner to choose from, and at the same time display the image data of the examinee's eyes in real time as well as the interactive information with the examinee, such as adjustment parameters, inspection progress, etc., making the operation process more intuitive and transparent. The prompt module effectively guides the examinee through voice or text prompts, informing him of the precautions and cooperation actions during the inspection process to ensure the smooth progress of the inspection.

[0045] Communications and Data Management The slit lamp device is also equipped with a communication device that can transmit imaging results and examination data to cloud storage in real time. This function not only facilitates remote sharing and long-term storage of data, but also provides strong support for telemedicine. Doctors can access cloud data anytime and anywhere for remote diagnosis and case analysis, which expands the application scenarios of slit lamps, improves the accessibility and continuity of medical services, and facilitates the long-term tracking and management of the patient's condition.

[0046] In summary, the fully automatic slit lamp of this solution realizes the automated operation, intelligent fault diagnosis and efficient data management of the slit lamp through the close cooperation of various parts, which greatly improves the efficiency, accuracy and reliability of ophthalmic examinations, and provides strong technical support for the development of ophthalmic medical care.

[0047] The second set of technical solutions is the intelligent diagnosis method of the fully automatic slit lamp.

[0048] The fully automatic slit lamp of this solution also has an intelligent fault diagnosis function. When the device is running, the computing element monitors the image data transmitted by the camera element in real time. Once an abnormality is detected in the imaging result, such as blur, noise, distortion, too bright or too dark, viewing angle deviation, color deviation, etc., the computing element will immediately mark the abnormality and enter the diagnostic mode. In this mode, the slit lamp device will automatically run different preset modes multiple times. The computing unit analyzes all abnormal imaging results through a visual algorithm, comprehensively considers the possible abnormal parameters corresponding to the abnormal elements, such as brightness, light source angle, observation angle, etc., and infers the possible abnormal components. Finally, by intersecting these possibilities, the computing unit can accurately locate the faulty component and clearly display the faulty component information to the inspector through the display module 1, providing clear guidance for subsequent repairs and maintenance.

[0049] Please refer to the following table 1 for troubleshooting: Table 1. Troubleshooting table

[0050] Specific working process The operator first selects a preset working mode through the display module 1 of the human-machine interaction device and inputs the inspection requirements.

[0051] After receiving the mode information, the calculation module quickly calculates the operating parameters of each component of the slit lamp device. Subsequently, the adjustment module of the automatic adjustment device accurately drives the slit lamp device through gear transmission according to the calculation results, including adjusting the imaging adjustment structure 2, the lens structure 3, the slit rotation angle adjustment structure 4 and other key components to achieve the state required by the preset mode.

[0052] The imaging element of the slit lamp device starts to work, converting the light guided by the imaging component into an electrical signal to generate image data of the subject's eye.

[0053] The display module 1 of the human-machine interaction device displays the eye image in real time, and the operator can directly observe the inspection process. During the operation of the equipment, the computing component continuously monitors the image data transmitted by the camera component. Once an abnormal imaging result is detected, it is immediately marked and enters the fault diagnosis mode.

[0054] The slit lamp device then runs different preset modes multiple times, and the computing unit analyzes all abnormal feedback of imaging results through visual algorithms. The abnormal feedback includes abnormal elements, abnormal parameters and abnormal components. It comprehensively considers the possible abnormal parameters corresponding to the abnormal elements, infers the possible abnormal components, and accurately locates the abnormal components based on the intersection possibilities. The specific method is: Construct the mapping relationship between abnormal elements, abnormal parameters and abnormal components. The specific mapping relationship is shown in Table 1. The abnormal elements in the abnormal imaging results are obtained through visual algorithm analysis, and the possible abnormal parameters and the existing abnormal components are obtained based on the mapping relationship; In different preset modes, the faulty component is obtained based on the intersection of the abnormal components obtained based on the mapping relationship.

[0055] For example, in a preset mode (eyelid inspection), the abnormal element obtained through visual algorithm analysis is: blur; at this time, the abnormal components obtained based on the mapping relationship are: focus system, lens; In another preset mode (conjunctival inspection), the abnormal element obtained through visual algorithm analysis is: distortion; at this time, the abnormal components obtained based on the mapping relationship are: lens and lens mount.

[0056] In summary, the intersection of the faulty components in the above two preset modes is the "lens". Therefore, the setting of multiple preset modes in the present application can not only make the functions of the slit lamp itself more complete, but also realize more accurate troubleshooting of faulty components based on the operation of different modes.

[0057] The fault component information is presented to the operator through the display module 1.
