The application discloses an oral endoscope auxiliary device and an oral endoscope, and relates to the technical field of medical equipment, and can solve the problems of shaking during handheld shooting, blind area coverage caused by operation without guidance, and focusing blur caused by depth of field of a traditional oral endoscope lens. The oral endoscope auxiliary device comprises a spatial positioning structure which is fixed opposite to a lens of the oral endoscope during shooting. The spatial positioning structure comprises at least one first contact part and at least one second contact part. The first contact part is configured to contact a first area in the oral cavity, and the second contact part is configured to contact a second area in the oral cavity. The first area and the second area are spatially separated. The first contact part and the second contact part jointly define the distance between the lens and a shooting area and the freedom degree of movement of the lens of the oral endoscope relative to the teeth, and keep the distance between the lens and the teeth unchanged and the freedom degree of movement of the lens unchanged. The oral endoscope auxiliary device can realize more comprehensive and clearer oral cavity examination.

This application discloses a method, apparatus, and electronic device for determining the microstructural parameters of trabecular bone, relating to the field of oral medicine technology, and invented to reduce the error in determining the microstructural parameters of trabecular bone. The method includes: acquiring a first three-dimensional image of the trabecular bone; wherein the first three-dimensional image is an image based on cone-beam computed tomography (CBCT); predicting the pixel values ​​of the second three-dimensional image based on the coordinates of a second three-dimensional image to be generated and features of the first three-dimensional image; wherein the resolution of the second three-dimensional image is higher than the resolution of the first three-dimensional image; generating the second three-dimensional image based on the pixel values ​​and coordinates of the second three-dimensional image; and determining the microstructural parameters of the trabecular bone based on the second three-dimensional image. This application is applicable to clinical oral examinations.

The invention belongs to the technical field of pediatric oral cavity examination, and particularly relates to a pediatric oral cavity tongue pressing device which comprises a bow arm and a supporting block. In the invention, a doctor expands the bow arm by holding the push rod and slowly applying thrust, and the bow arm is slowly pushed by the support of the long handle connecting rod and the limit of the auxiliary connecting rod. A patient stretches the tongue into an interlayer between the tongue depressor and the arch arm and keeps the tongue still. When the oral cavity of the patient expands to a sufficient degree for examination, a doctor holds the push rod with one hand to continuously keep the arch arm expanded, and the other hand pokes the medical camera to adjust the shooting range, and examines the oral cavity of the patient through an imaging picture imported into a computer until the touch control panel is lightly pressed to control the shutter to shoot a picture. In the process, the light supplementing lamp continuously performs light supplementing illumination on the oral cavity of the patient, and the shooting definition is guaranteed. After oral examination is completed, a doctor slowly loosens the push rod, and the bow arm is slowly reset and closed through pressure applied by the spring. Through the linkage design of the push rod and the U-shaped frame, the whole process of expansion-shooting is controlled by two hands.

The application relates to the technical field of oral cavity expansion, and discloses an oral cavity auxiliary expansion device for oral cavity examination, which comprises two main bodies, a support arm rotatably connected between the two main bodies, and a rotating mechanism installed in the interior of the main body and used for ensuring the comfort of a patient when the patient's mouth corners are expanded. When the rotating plate I is flipped, the planar area of the rotating plate I faces the patient's mouth corners, at this time, the rotating plate I and the patient's mouth corners provide a contraction space, so that the patient's mouth corners can be slightly contracted, the patient's mouth corners are protected, tearing pain caused by long-time expansion of the patient's mouth corners and cheeks is reduced, and the comfort of the patient during long-time expansion of the main body is improved.

Embodiments described herein involve converting written assessments into oral assessments, which may be conversational in nature. The oral assessments may be better at determining the knowledge of an assessee. Additionally, the oral assessments are less vulnerable to academic dishonesty. Embodiments also generate an answer form similar to an answer form that would be used with the written assessment, thereby allowing assessors to seamlessly continue using their practiced assessment methods. In embodiments, a computer-implemented method of examination involves processing a written assessment through a machine learning model to generate an oral assessment, which is then transmitted to an assessee. The assessee responds to the oral assessment, and the response is analyzed using the machine learning model to determine one or more answers to the written assessment. A completed answer form to the written assessment is generated using these answers.

This invention discloses a crosstalk discrimination method for oral examination scenarios, belonging to the field of speech intelligence technology. The method includes four steps: data preparation, feature extraction, training a discrimination model, and examination discrimination. A dataset is constructed by collecting audio from multiple examination scenarios, 80-dimensional Fbank features are extracted, and a lightweight deep learning model is used to output crosstalk confidence under mono audio conditions. Combined with threshold and multi-dimensional information for joint discrimination, accurate differentiation between target speech and crosstalk is achieved. This invention requires no additional hardware such as microphone arrays, has fewer model parameters, lower computational cost, and lower deployment cost. It can effectively suppress crosstalk interference, avoid misscoring, and significantly improve the accuracy, fairness, and robustness of oral examination scoring, making it suitable for large-scale standardized oral examination scenarios.
