Description

Technical Field

[0001] This invention belongs to the field of oral endoscopy technology, and specifically relates to an oral endoscopy auxiliary device. Background Technology

[0002] As an important tool for modern oral care and diagnosis, the core function of an oral endoscope is to use a miniature camera to image and magnify the internal structures of the oral cavity, such as tooth surfaces, gingival sulci, lingual surfaces, and areas that are difficult to see directly, and display them on an external screen in real time. This greatly assists users in conducting daily oral health self-checks and helps dentists with initial diagnoses, explaining conditions, and recording treatment processes, improving the convenience and visualization of oral health management.

[0003] Currently, most mainstream oral endoscopes on the market are integrated handheld designs, and their optical imaging modules (oral endoscope lenses) typically use fixed-focus lenses with a fixed focal length. While this design is structurally simple, it also brings significant inherent limitations. On the one hand, a fixed focal length means a fixed depth of field. In actual operation, due to the small space and complex structure inside the oral cavity, it is difficult for users or doctors to maintain the lens tip at a precise optimal focusing distance from the target tooth or gingival tissue. Once the operating distance deviates from the depth of field, the image will quickly become blurred, resulting in the inability to clearly capture detailed features (such as early plaque, tiny cavities, or gingival inflammation), seriously affecting the accuracy of observation and the effectiveness of diagnosis.

[0004] On the other hand, the purely handheld operation mode introduces many unstable factors. First, without physical guidance and spatial positioning assistance, operators (whether ordinary users or professional doctors) rely solely on touch and visual judgment to move the intraoral endoscope within the mouth, which easily leads to random examination paths, incomplete field of view coverage, and the easy omission of certain hidden areas (such as the distal surface of the last molar). Second, because the intraoral endoscope provides a localized, magnified image, any slight, involuntary hand tremor will be amplified into noticeable screen shaking, resulting in a poor user experience and examination comfort.

[0005] Therefore, there is an urgent need for an oral endoscope product with stable support and precise spatial positioning guidance to solve the pain points such as handheld shooting shakiness, blind spots caused by lack of guidance during operation, and blurry focus caused by depth of field, so as to achieve a more comprehensive, clearer, and more comfortable oral examination. Summary of the Invention

[0006] One of the objectives of this invention is to disclose an oral endoscope auxiliary device that at least solves the pain points of oral endoscope lenses in the background art, such as handheld shooting shakiness, blind spots caused by lack of operation guidance, and blurry focus caused by depth of field, so as to achieve a more comprehensive, clearer, and more comfortable oral examination.

[0007] The second objective of this invention is to disclose an oral endoscope, which employs the aforementioned oral endoscope auxiliary instruments, enabling the oral endoscope to obtain clear images when taking pictures inside the oral cavity.

[0008] To achieve the above objectives, the present invention discloses an oral endoscope auxiliary device, which includes a spatial positioning structure. When the oral endoscope is taking pictures of the imaging area, the spatial positioning structure is fixed relative to the oral endoscope lens. The spatial positioning structure includes at least one first contact portion and at least one second contact portion. The first contact portion is configured to contact a first region inside the oral cavity, and the second contact portion is configured to contact a second region inside the oral cavity. The first region and the second region are spatially separated. When the oral endoscope is taking pictures of the imaging area, the oral endoscope is placed inside the oral cavity, such that the first contact portion and the second contact portion respectively contact the first region and the second region. The first contact portion and the second contact portion together define the distance between the oral endoscope lens and the imaging area and the degree of freedom of the oral endoscope lens relative to the teeth, and keep the distance between the oral endoscope lens and the imaging area within the imaging depth range of the oral endoscope lens, keeping the degree of freedom of lens movement unchanged.

[0009] As an optional embodiment, the spatial positioning structure further includes a mounting part, wherein the first contact part and the second contact part are both fixedly mounted to the mounting part, and the mounting part is separately disposed from the intraoral endoscope lens.

[0010] As an optional embodiment, the spatial positioning structure further includes a mounting portion, wherein the first contact portion and the second contact portion are both fixedly mounted to the mounting portion, and the mounting portion is integrally formed with the intraoral endoscope lens.

[0011] As an optional embodiment, the first region is the occlusal surface of a tooth. When the intraoral endoscope takes pictures of the area, the intraoral endoscope is placed inside the oral cavity, and the first contact part contacts the occlusal surface of the tooth. The second region is the gingival side. When the intraoral endoscope is used to take pictures of the area, the intraoral endoscope is placed inside the oral cavity, and the second contact part contacts the gingival side. And / or the second region is the side of a tooth. When the intraoral endoscope takes pictures of the area, the intraoral endoscope is placed in the oral cavity, and the second contact part contacts the side of the tooth. The first contact portion and the second contact portion together define the distance between the endoscope lens and the imaging area and the degree of freedom of the endoscope lens relative to the teeth, and keep the distance between the endoscope lens and the imaging area within the imaging depth range of the endoscope lens, keeping the degree of freedom of lens movement unchanged.

[0012] As an optional embodiment, there are two first contact portions, which are arranged in parallel. When the oral endoscope takes pictures of the imaging area, the oral endoscope is placed inside the oral cavity, and both first contact portions are in contact with the occlusal surface of the teeth.

[0013] As an optional embodiment, the second contact portion is provided, and when the oral endoscope is taking pictures of the imaging area, the oral endoscope is placed in the oral cavity, and the second contact portion contacts the labial side of the gingiva or the dental side of the gingiva or the labial side of the tooth or the dental side of the tooth. Alternatively, two second contact portions are provided, and the two second contact portions are arranged opposite to each other. When the oral endoscope takes pictures of the imaging area, the oral endoscope is placed in the oral cavity, wherein one of the second contact portions contacts the labial side of the gingiva or the labial side of the tooth, and the other second contact portion contacts the dental side of the gingiva or the dental side of the tooth.

[0014] As an optional embodiment, the first contact portion includes a first connecting portion and a first contact surface. The first connecting portion is fixedly connected to the mounting portion, and the first contact surface is disposed on the first connecting portion and faces the occlusal surface of the teeth. When the oral endoscope takes pictures of the imaging area, the oral endoscope is placed in the oral cavity, the first contact surface contacts the occlusal surface of the teeth, and the first connecting portion at least limits the distance between the lens of the oral endoscope and the imaging area. The first contact surface is provided with a central concave area, which is used to contact the occlusal surface of the anterior teeth. The two sides of the central concave area are respectively provided with protruding areas, which are used to support the tooth surface of the posterior molars.

[0015] As an optional embodiment, the second contact portion includes a second connecting portion and a second contact surface. The second connecting portion is fixedly connected to the mounting portion, and the second contact surface is disposed on the second connecting portion. The second contact surface faces the labial side of the gingiva and / or the dental side of the gingiva and / or the labial side of the tooth and / or the dental side of the tooth. When the oral endoscope takes pictures of the imaging area, the oral endoscope is placed in the oral cavity, and the second contact surface contacts the labial side of the gingiva and / or the dental side of the gingiva and / or the labial side of the teeth and / or the dental side of the teeth. The second contact surface and the first contact portion simultaneously limit the degree of freedom of movement of the oral endoscope lens. The second connecting part includes a connecting arc plate, one end of which is fixedly connected to the mounting part, and the other end of which is provided with a second contact surface, with the inner arc surface of the connecting arc plate facing the tooth side.

[0016] As an optional embodiment, both the first and second contact portions are made of a smooth and elastic material.

[0017] As an optional embodiment, the oral endoscope aid further includes a lens module disposed in front of the oral endoscope lens.

[0018] As an optional embodiment, the oral endoscope auxiliary device further includes a second lens; the second lens may have the same or different shooting area as the oral endoscope lens, and the second lens and the oral endoscope lens may have the same or different shooting angles for the same shooting area.

[0019] As an optional embodiment, the oral endoscope aid further includes a supplementary light and a portable power source, wherein the portable power source powers at least the supplementary light; The supplemental light includes natural light mode and / or ultraviolet light mode and / or infrared light mode.

[0020] An oral endoscope, including the aforementioned oral endoscope aids.

[0021] Compared with the prior art, the beneficial effects of the oral endoscope auxiliary device of the present invention are as follows: 1. Stabilizes the imaging working distance between the lens and the shooting area, improving imaging stability and clarity.

[0022] This invention constrains the position of the oral endoscope within the oral cavity by setting a spatial positioning structure that contacts the teeth and / or gums. This limits the relative distance between the lens and the imaging area to a predetermined imaging working distance, thereby avoiding imaging blurring caused by changes in imaging distance exceeding the depth of field and improving the stability and consistency of intraoral imaging images.

[0023] 2. By forming geometric constraints through contact with multiple areas within the oral cavity, it significantly reduces shaking and offset during the imaging process.

[0024] Because the spatial positioning structure constrains the intraoral endoscope lens through at least two first and second contact parts that form with different areas inside the oral cavity, it creates a stable geometric support relationship inside the oral cavity. This restricts the degree of freedom of the intraoral endoscope lens in the directions of rotation, forward and backward movement, and lateral offset, effectively suppressing the magnification effect of minor hand tremors in the image and improving the stability during the shooting process.

[0025] 3. Reduce reliance on user experience and improve the ease of use and repeatability of intraoral imaging.

[0026] This invention defines the distance between the lens and the shooting area and the degree of freedom of the oral endoscope lens relative to the teeth by using the first contact part and the second contact part together. That is, the spatial positioning and distance limitation are achieved by the structure of the first contact part and the second contact part itself, rather than relying on the user to control the shooting distance and angle by feel. This reduces the requirements for the operator's experience and skills, and allows different users to obtain more consistent imaging effects when shooting at different times, thus improving the repeatability of the shooting results.

[0027] 4. It guides the user's operation path during the shooting process, improving the completeness of dental arch imaging.

[0028] This invention defines the distance between the lens and the imaging area and the degree of freedom of the intraoral endoscope lens relative to the teeth through the first contact part and the second contact part. During use, the spatial positioning structure can move along the dental arch curve when in contact with the teeth, thereby passively guiding the movement direction of the intraoral endoscope. This allows the user to perform continuous scanning and imaging according to the dental arch structure, reducing the problems of missed images and incomplete coverage, ensuring that the target area can be systematically and without omission, and facilitating the acquisition of systematic and complete oral imaging data.

[0029] 5. Facilitates widespread application and reduces modification costs.

[0030] This invention, by adding a spatial positioning structure, can be applied to different types and structural forms of oral endoscope products, thereby improving performance without changing the core structure of existing equipment, and has high versatility and promotional value.

[0031] Compared with the prior art, the beneficial effects of the oral endoscope of the present invention are as follows: The oral endoscope of the present invention uses the aforementioned oral endoscope auxiliary device, which enables the oral endoscope to obtain images with good stability, consistency and clarity when taking pictures inside the oral cavity.

[0056] The technical solution of the present invention will be further described below with reference to the embodiments and accompanying drawings.

[0057] Please see Figures 1-17 As shown in the figure, this application provides an oral endoscope assist device 20.

[0058] In one embodiment, please refer to Figures 1-2 as well as Figures 5-6 An oral endoscope aid 20 includes a spatial positioning structure. When the oral endoscope 10 takes pictures of the imaging area, the spatial positioning structure is fixed relative to the oral endoscope lens 101.

[0059] The spatial positioning structure includes at least one first contact portion 1 and at least one second contact portion 2, the first contact portion 1 being configured to contact a first region within the oral cavity, and the second contact portion 2 being configured to contact a second region within the oral cavity, wherein the first region and the second region are spatially separated.

[0060] When the oral endoscope 10 takes pictures of the imaging area, the oral endoscope 10 is placed in the oral cavity, and the first contact part 1 and the second contact part 2 are in contact with the first area and the second area respectively. The first contact part 1 and the second contact part 2 together limit the distance between the lens and the imaging area and the degree of freedom of the oral endoscope lens relative to the teeth, and keep the distance between the lens and the teeth unchanged, and keep the degree of freedom of the lens movement unchanged.

[0061] The oral endoscope auxiliary device 20 of this embodiment fixes the spatial positioning structure relative to the oral endoscope lens 101. The spatial positioning structure includes a first contact part 1 and a second contact part 2. When the oral endoscope takes pictures of the oral cavity, the first contact part 1 and the second contact part 2 contact the first region and the second region in the oral cavity, respectively, and the first region and the second region are spatially separated. In this way, the spatial positioning structure has contact and support with the oral cavity at least at two positions, which constrains the spatial position of the oral endoscope 10 in the oral cavity. This limits the relative distance between the oral endoscope lens 101 and the imaging area to a predetermined imaging working distance range, thereby avoiding the imaging blurring problem caused by the imaging distance changing beyond the depth of field range. This improves the stability and consistency of the intraoral imaging images, obtains stable and clear images, and greatly improves the readability of user self-examination and the accuracy of doctor diagnosis.

[0062] The oral endoscope auxiliary device 20 of this embodiment fixes the spatial positioning structure relative to the oral endoscope lens 101. The spatial positioning structure includes a first contact portion 1 and a second contact portion 2. When the oral endoscope takes pictures inside the oral cavity, the first contact portion 1 and the second contact portion 2 contact the first and second regions inside the oral cavity, respectively. The first contact portion 1 and the second contact portion 2 together limit the distance between the lens and the imaging area and the degree of freedom of the oral endoscope lens relative to the teeth, while keeping the distance between the lens and the teeth constant and maintaining the degree of freedom of lens movement constant. This creates a stable geometric support relationship for the oral endoscope lens 101 inside the oral cavity, thereby limiting the degree of freedom of the oral endoscope in rotation, forward and backward movement, and lateral displacement, effectively suppressing the magnification effect of minor hand tremors in the image, and improving stability during the imaging process. When operators or users use the oral endoscope auxiliary device 20 of this embodiment to take pictures of the intraoral imaging area, they no longer need to rely on touch for high-precision, fatigue-resistant stable control, reducing the operational threshold and technical burden. The freedom of movement of the oral endoscope lens is limited, which allows the oral endoscope lens 101 to be guided during movement. This makes the examination process easier and more systematic, improves the comfort of using the oral endoscope 10, and ensures the completeness and integrity of the imaging area. It transforms the examination process from an unguided "blind exploration" to a trackable "scan", ensuring that all imaging areas can be systematically and without omission.

[0063] The oral endoscope auxiliary device 20 of this embodiment fixes the spatial positioning structure relative to the oral endoscope lens 101. The spatial positioning structure includes a first contact portion 1 and a second contact portion 2. When the oral endoscope takes pictures of the oral cavity, the first contact portion 1 and the second contact portion 2 contact a first region and a second region within the oral cavity, respectively. The first contact portion 1 and the second contact portion 2 together define the distance between the lens and the imaging area and the degree of freedom of the oral endoscope lens relative to the teeth. The distance and degree of freedom between the lens and the imaging area are jointly achieved by the structure of the first contact portion 1 and the second contact portion 2, rather than relying on the user's manual control of the shooting distance and angle. This reduces the requirements for the operator's experience and skills, allowing different users to obtain relatively consistent imaging results at different times, thus improving the repeatability of the shooting results. The use of the spatial positioning structure in this embodiment, which defines the distance between the lens and the imaging area and the degree of freedom of the lens, solves the inherent defects of the oral endoscope lens 101 without changing the internal structure and optical system of the oral endoscope, making it economical and convenient.

[0064] In this embodiment, when the intraoral endoscope 10 is taking pictures of the imaging area, the spatial positioning structure is relatively fixed to the intraoral endoscope lens 101. That is, when the intraoral endoscope 10 is taking pictures of the imaging area, the spatial positioning structure must be relatively fixed to the intraoral endoscope lens 101. The spatial positioning structure limits the distance between the lens and the imaging area and the degree of freedom of the intraoral endoscope lens relative to the teeth, and keeps the distance between the lens and the teeth constant, and keeps the degree of freedom of the lens movement constant. In other embodiments, when the intraoral endoscope 10 is not taking pictures of the imaging area, the spatial positioning structure and the intraoral endoscope lens 101 are not necessarily fixed or relatively fixed. For example, the spatial positioning structure is only fixed to the intraoral endoscope 10 when the intraoral endoscope 10 is taking pictures of the imaging area. If the spatial positioning structure is integrally fixed to the intraoral endoscope lens 101, then the spatial positioning structure must always be relatively fixed to the intraoral endoscope lens 101.

[0065] In this embodiment, the spatial positioning structure includes at least one first contact portion 1 and at least one second contact portion 2. For example... Figure 2 In this configuration, there is one first contact part 1 and two second contact parts 2. For example... Figure 1 In this configuration, there is one first contact part 1 and two second contact parts 2. For example... Figure 5 In the diagram, the first contact part 1 has two parts, and the second contact part 2 has one part. For example... Figure 6 In the middle, there are two first contact parts 1 and one second contact part 2.

[0066] In some embodiments, the spatial positioning structure includes a first contact portion 1 and a second contact portion 2. In other embodiments, the spatial positioning structure includes a first contact portion 1 and two or more second contact portions 2. In still other embodiments, the spatial positioning structure includes two or more first contact portions 1 and a second contact portion 2. In yet another embodiment, the spatial positioning structure includes two or more first contact portions 1 and two or more second contact portions 2.

[0067] In this embodiment, the first region and the second region refer to different locations within the oral cavity. The first region and the second region are spatially separated, meaning that the first region and the second region within the oral cavity are not on the same horizontal plane. In one embodiment, the first region and the second region are in two non-parallel planes.

[0068] In this embodiment, the first contact portion 1 and the second contact portion 2 jointly define the distance between the lens and the shooting area, and keep the distance between the lens and the teeth constant. This means that by the joint definition of the first contact portion 1 and the second contact portion 2, the distance between the oral endoscope lens 101 and the surface of the shooting area during use is limited to a predetermined imaging working distance range of the oral endoscope lens 101. This makes the distance between the shooting area and the oral endoscope lens 101 compatible with the focal length of the oral endoscope lens 101, and makes the distance between the shooting area and the oral endoscope lens 101 within the depth of field range of the oral endoscope lens 101. This improves the stability and clarity of the image of the shooting area captured by the oral endoscope lens 101, so that the clearest image quality can be obtained every time the target shooting area is captured, eliminating blurring caused by improper operating distance, and fully utilizing the imaging potential of existing fixed-focus oral endoscopes.

[0069] In this embodiment, when the intraoral endoscope 10 takes pictures of the imaging area, the intraoral endoscope 10 is placed inside the oral cavity, and the first contact part 1 and the second contact part 2 are in contact with the first area and the second area, respectively. This allows the first contact part 1 and the second contact part 2 to jointly limit the degree of freedom of the lens movement relative to the teeth, maintaining this degree of freedom during the imaging process. This means that the first contact part 1 and the second contact part 2 jointly limit the movement, ensuring that the intraoral endoscope lens 101 with its spatial positioning structure has a clear and stable guide track during use. This transforms the examination process from unguided "blind exploration" to a tracked "scan," ensuring systematic and comprehensive coverage of the target imaging area. For example, when the spatial positioning structure contacts the teeth, it can move along the dental arch curve, thus guiding the imaging path of the intraoral endoscope lens 101 and enabling the user to continuously and systematically acquire images of the dental arch.

[0070] In one embodiment, the first region is the occlusal surface of the teeth. When the intraoral endoscope 10 takes pictures of the area, the intraoral endoscope 10 is placed inside the oral cavity, and the first contact part 1 contacts the occlusal surface of the teeth.

[0071] The first contact portion 1 contacts the occlusal surface of the teeth, which provides the primary contact point, ensuring a stable distance between the endoscope lens and the teeth, thereby achieving clear imaging. Furthermore, the contact between the first contact portion 1 and the occlusal surface facilitates the operator's grip and application of force on the endoscope handle during operation, keeping the endoscope stable. The operator only needs to apply a small amount of pressure to maintain contact between the first contact portion 1 and the occlusal surface, thus ensuring the stability of the endoscope lens and maintaining a stable distance between the endoscope lens and the teeth.

[0072] The second region is spatially separated from the first region, and the second region and the first region are not in the same plane. Furthermore, the first region and the second region are in two non-parallel planes.

[0073] In some embodiments, the second region is the gingival side. When the intraoral endoscope 10 takes a picture of the area, the intraoral endoscope 10 is placed inside the oral cavity, and the second contact portion 2 contacts the gingival side. The gingival side includes the gingiva facing lingually and the gingiva facing labially. The second contact portion 2 contacts the second region, that is, the second contact portion 2 contacts the lingual and / or labial side of the gingiva. When there is only one second contact portion 2, or when each second contact portion 2 is only provided on the same side of the mounting portion 3, the second contact portion 2 contacts only the lingual or labial side of the gingiva. When there are two second contact portions 2, and they are provided on both sides of the mounting portion 3, the second contact portion 2 contacts both the lingual and labial sides of the gingiva.

[0074] In other embodiments, the second region is a tooth lateral surface, which includes a labial side and a lingual side. The second contact portion 2 contacts the labial side and / or the lingual side of the tooth.

[0075] In other embodiments, the second region includes the tooth side and the gingival side, i.e., the second region is the gingival side facing the tongue or the gingival side facing the labial side, and the tooth side facing the labial side or the tooth side facing the tongue.

[0076] The second contact part 2 contacts the second region, which serves as a second contact point, providing additional support to further stabilize the position of the oral endoscope lens and reduce the impact of minor hand tremors or positional shifts. Through this design, the oral endoscope lens can maintain a stable distance and orientation (degrees of freedom) during imaging, thanks to the coordinated action of multiple contact points, thus ensuring the accuracy and clarity of the imaging results.

[0077] The first contact part 1 contacts the occlusal surface of the tooth, and the second contact part 2 contacts the gingival lateral surface and / or the lateral surface of the tooth. This together limits the distance between the lens and the imaging area and the degree of freedom of movement of the intraoral endoscope lens relative to the teeth, while maintaining a constant distance between the lens and the teeth and a constant degree of freedom of lens movement. This ensures that the distance between the intraoral endoscope lens and the tooth or gingival surface is limited within a predetermined imaging working distance during use, thereby improving the stability and clarity of the captured images. Furthermore, during use, the spatial positioning structure of the intraoral endoscope lens can move along the dental arch curve when in contact with the teeth and / or gums, thus guiding the user's imaging path and enabling continuous and systematic image acquisition of the dental arch.

[0078] In some embodiments, the imaging area is the occlusal surface of the teeth.

[0079] In other embodiments, the imaging area is the side of the teeth and / or the side of the gums.

[0080] In some embodiments, the first region and the second region may also be the back cheek or tongue of the upper or lower jaw inside the oral cavity.

[0081] In one embodiment, please refer to Figure 1 , Figure 5 and Figure 6 The device has two first contact parts 1, which are arranged in parallel. When the intraoral endoscope 10 is used to take pictures of the imaging area, the intraoral endoscope 10 is placed inside the oral cavity, and both first contact parts 1 are in contact with the occlusal surfaces of the teeth. Having two first contact parts 1 increases the contact area and the number of contact positions, making it easier for the operator to maintain stable contact between the first contact parts 1 and the occlusal surfaces of the teeth during operation. This also helps to maintain a fixed distance between the intraoral endoscope lens 101 and the imaging area, preventing problems such as tilting or shifting of the intraoral endoscope lens 101 during operation.

[0082] In one embodiment, please refer to Figure 1 and Figure 5 In this embodiment, the orientation of the two first contact portions 1 is consistent with the orientation of the intraoral endoscope lens 101. At this time, the intraoral endoscope lens 101 captures images of the occlusal surface of the teeth; that is, the imaging area is on the occlusal surface of the teeth. The first contact portions 1 define the distance between the intraoral endoscope lens 101 and the occlusal surface of the teeth. In some embodiments, the intraoral endoscope lens 101 is disposed between the two first contact portions 1, and the orientation of the first contact portions 1 is consistent with the orientation of the intraoral endoscope lens 101. In some embodiments, the intraoral endoscope lens 101 is disposed outside the two first contact portions 1, and the orientation of the first contact portions 1 is consistent with the orientation of the intraoral endoscope lens 101.

[0083] In some embodiments, there are two first contact parts 1, and the orientation of the two first contact parts 1 is consistent with the orientation of the oral endoscope lens 101. In this case, regardless of whether the oral endoscope lens 101 is located between or on the outside of the two first contact parts 1, the manufacturer can adjust the distance between the two first contact parts 1 according to the user's needs, such as the user's target or the user's requirements for the field of view of the shot, during the production of the oral endoscope auxiliary device 20.

[0084] In other embodiments, such as Figure 2 As shown, a first contact portion 1 is provided, and the orientation of the first contact portion 1 is consistent with the orientation of the intraoral endoscope lens 101. The single first contact portion 1 reduces the volume of the spatial positioning structure, thereby reducing the overall volume of the intraoral endoscope 10. This results in less foreign body sensation when the intraoral endoscope 10 is used for imaging, improving the comfort of the patient, or facilitating its application in pediatric oral examinations, thus enhancing the adaptability of the intraoral endoscope 10.

[0085] In one embodiment, please refer to Figure 6 and Figure 8 At this time, the first contact part 1 is located on the outside of the intraoral endoscope lens 101, and the orientation of the first contact part 1 is at an acute angle to the orientation of the intraoral endoscope lens 101. Thus, when the intraoral endoscope 10 of this embodiment is working, the first contact part 1 is in contact with the occlusal surface of the teeth, and the intraoral endoscope lens 101 is facing the side of the teeth and / or the side of the gums. At this time, the imaging area is on the side of the teeth and / or the side of the gums.

[0086] Please refer to the above embodiments. Figure 8 The first contact portion 1 contacts the occlusal surface of the teeth, and the intraoral endoscope lens 101 captures images of the lateral surfaces of the teeth and / or the lateral surfaces of the gums. The first contact portion 1 also defines the height between the intraoral endoscope lens 101 and the imaging area. Please refer to... Figure 8 The first contact portion 1 is combined with the second contact portion 2, and the first contact portion 1 is in contact with the occlusal surface of the tooth, while the second contact portion 2 is in contact with the lateral surface of the tooth and / or the lateral surface of the gum. The first contact portion 1 and the second contact portion 2 together define the degrees of freedom of movement of the oral endoscope lens 101.

[0087] In one embodiment, please refer to Figures 3-4In this embodiment, the first contact portion 1 includes a first connecting portion 11 and a first contact surface 12. The first connecting portion 11 is fixedly connected to the mounting portion 3, and the first contact surface 12 is disposed on the first connecting portion 11, with the first contact surface 12 facing the occlusal surface of the teeth. When the intraoral endoscope 10 takes pictures of the imaging area, the intraoral endoscope 10 is placed inside the oral cavity, and the first contact surface 12 contacts the occlusal surface of the teeth. The first connecting portion 11 at least limits the distance between the lens and the imaging area. The first contact surface 12 is provided with a central concave area 121, which is used to contact the occlusal surface of the anterior teeth. The two sides of the central concave area 121 are respectively provided with protruding areas 122, which are used to support the tooth surface of the posterior molars.

[0088] The height of the first connecting part 11 is used to limit the distance between the oral endoscope lens 101 and the occlusal surface of the teeth, that is, to indirectly limit the distance between the oral endoscope lens 101 and the imaging area.

[0089] The first contact surface 12 is used for contact with the occlusal surface of the teeth. (See also...) Figures 3-4 The central concave region 121 on the first contact surface 12 facilitates the insertion and fixation of the anterior teeth. The central concave region 121 is triangular in shape, which helps to fix the anterior teeth within it, achieving fixation and preventing slippage between the first contact surface 12 and the anterior teeth during the movement of the intraoral endoscope 10. The protruding regions 122 on both sides of the central concave region 121 facilitate support on the tooth surface of the posterior molars. In one embodiment, please refer to... Figure 5 The width D1 of the first contact portion 1 is 12mm, that is, the width D1 of the first contact surface 12 is 12mm, which ensures that the first contact surface 12 can land relatively stably on the teeth, especially the molars, so that the molars can be stuck between the two protruding areas 122.

[0090] In one embodiment, please refer to Figure 5 The width D1 of the first contact surface 12 is greater than 10mm but less than 15mm.

[0091] In one embodiment, considering the smooth movement of the oral endoscope 10 on the occlusal surface of the teeth, the thickness D2 of the first contact portion 1 should be set to a relatively thick range. Generally, the thickness D2 of the first contact portion 1 should ensure that it exceeds the distance between the canines of two adjacent teeth, thus ensuring that the first contact portion 1 moves relatively smoothly on the occlusal surface of the teeth. For example, please refer to... Figure 5 The thickness D2 of the first contact portion 1 is greater than 5 mm but less than 10 mm.

[0092] In another embodiment, considering the miniaturization of the oral endoscope 10 product, the width D1 of the first contact portion 1 can be set to a narrower range, such as the thickness of the first contact portion 1 being less than 5 mm but greater than 2 mm.

[0093] When the oral endoscope 10 is working, the oral endoscope 10 needs to move along the curve of the teeth. The enlarged rounded corner of the first contact part 1 ensures that the oral endoscope 10 moves smoothly and at the same time reduces the friction of the oral endoscope 10 on the oral cavity wall during movement.

[0094] In one embodiment, the first contact surface 12 is provided with slots on both sides of the central concave area 121, and the slots are provided to facilitate the insertion of the posterior teeth.

[0095] In one embodiment, the first contact portion 1, the first connecting portion 11, and the first contact surface 12 can also be configured to other shapes and sizes that better conform to the physiological structure of teeth, according to user requirements.

[0096] In one embodiment, please refer to Figure 1 and Figure 2 There are two second contact parts 2, which are arranged opposite to each other and located on both sides of the endoscope lens 101. When the endoscope 10 takes pictures of the area, the endoscope 10 is placed in the oral cavity, one of the second contact parts 2 contacts the labial side of the gum or the labial side of the tooth, and the other second contact part 2 contacts the dental side of the gum or the dental side of the tooth.

[0097] like Figure 1 , Figure 2 and Figure 4 As shown, two second contact portions 2 are arranged opposite each other, and the two second contact portions 2 are respectively located on both sides of the intraoral endoscope lens 101. In this way, when the intraoral endoscope 10 takes pictures of the imaging area, the first contact portion 1 contacts the occlusal surface of the teeth, one of the second contact portions 2 contacts the labial side of the gingiva or the labial side of the teeth, and the other second contact portion 2 contacts the dental side of the gingiva or the dental side of the teeth. That is, the two second contact portions 2 are respectively located on both sides of the teeth. The two second contact portions 2 clamp the teeth or gingiva, thereby restricting the degree of freedom of movement of the intraoral endoscope 10, so that the intraoral endoscope 10 can only move along the dental arch curve of the teeth. Combined with the contact between the first contact portion 1 and the occlusal surface of the teeth, the intraoral endoscope lens 101 can only move along the dental arch curve of the teeth while maintaining a fixed distance from the imaging area.

[0098] In the above embodiment, two second contact portions 2 are provided, and the two second contact portions 2 are arranged opposite each other. The two second contact portions 2 are located on both sides of the intraoral endoscope lens 101. When the intraoral endoscope 10 is used to photograph the area, it is placed inside the oral cavity. One second contact portion 2 contacts the labial side of the gingiva or the labial side of the tooth, and the other second contact portion 2 contacts the dental side of the gingiva or the dental side of the tooth. In this embodiment, the distance between the two opposing second contact portions 2 is adapted to the thickness of the tooth or the gingiva, ensuring that the two second contact portions 2 are always in contact with both sides of the tooth or gingiva, while also ensuring that the intraoral endoscope 10 moves smoothly along the dental arch curve and avoiding excessive force on the gingiva or tooth interdental space, which could cause discomfort.

[0099] In one embodiment, please refer to Figure 5 and Figure 6 The second contact part 2 is provided. When the oral endoscope 10 takes pictures of the imaging area, the oral endoscope 10 is placed in the oral cavity, and the second contact part 2 contacts the labial side of the gingiva or the lingual side of the gingiva or the labial side of the teeth or the lingual side of the teeth.

[0100] Please see Figure 5 The first contact portion 1 is oriented in the same direction as the intraoral endoscope lens 101. After the first contact portion 1 contacts the occlusal surface of the tooth, the second contact portion 2 contacts the side of the tooth or the side of the gum, and the intraoral endoscope lens 101 takes pictures of the occlusal surface of the tooth. In this embodiment, only one second contact portion 2 is provided, which effectively reduces the size of the intraoral endoscope auxiliary instrument 20 and realizes the miniaturization of the intraoral endoscope auxiliary instrument 20. This allows the intraoral endoscope 10 using this intraoral endoscope auxiliary instrument 20 to be used in some special scenarios, such as for pediatric dental treatment. In this embodiment, when the intraoral endoscope lens 101 takes pictures of the occlusal surface of the tooth, the operator only needs to hold the handle of the intraoral endoscope 10 and apply a very small force to make the first contact portion 1 contact the occlusal surface of the tooth, while ensuring that the second contact portion 2 contacts one side of the tooth or one side of the gum.

[0101] Please see Figures 6-8 The first contact portion 1 is oriented at an acute angle to the orientation of the intraoral endoscope lens 101. After the first contact portion 1 contacts the occlusal surface of the tooth, the second contact portion 2 contacts the lateral surface of the tooth or the gingival surface, and the intraoral endoscope lens 101 takes pictures of the lateral surface of the tooth or the gingival surface. In this embodiment, when the intraoral endoscope lens 101 takes pictures of the lateral surface of the tooth or the gingival surface, the operator only needs to hold the handle of the intraoral endoscope 10 and apply a very small force to make the first contact portion 1 contact the occlusal surface of the tooth, while ensuring that the second contact portion 2 contacts one side of the tooth or one side of the gingival surface. In this embodiment, the first contact portion 1 and the second contact portion 2 together limit the degree of freedom of movement of the intraoral endoscope lens 101.

[0102] In one embodiment, please refer to Figure 3 and Figure 7 The second contact portion 2 includes a second connecting portion 21 and a second contact surface 22. The second connecting portion 21 is fixedly connected to the mounting portion 3, and the second contact surface 22 is disposed on the second connecting portion 21, and the second contact surface 22 faces the labial side of the gingiva and / or the dental side of the gingiva and / or the labial side of the tooth and / or the dental side of the tooth.

[0103] When the oral endoscope 10 takes pictures of the imaging area, the oral endoscope 10 is placed inside the oral cavity, and the second contact surface 22 contacts the labial side of the gingiva and / or the dental side of the gingiva and / or the labial side of the teeth and / or the dental side of the teeth. The second contact surface 22 and the first contact part 1 simultaneously limit the degree of freedom of movement of the lens.

[0104] The second connecting part 21 includes a connecting arc plate. One end of the connecting arc plate is fixedly connected to the mounting part 3, and the other end of the connecting arc plate is provided with a second contact surface 22. The inner arc surface of the connecting arc plate faces the tooth side.

[0105] In this embodiment, the second contact portion 2 includes a second connecting portion 21, which includes a connecting arc plate. The inner arc surface of the connecting arc plate faces the tooth side surface. This design structure allows the second contact surface 22 to contact the tooth side surface and / or the gingival side surface, and the second connecting portion 21 will not interfere with the tooth and / or gingiva. This ensures stable contact between the second contact surface 22 and the tooth side surface and / or the gingival side surface, and allows the oral endoscope 10 to move along the dental arch curve when it is working.

[0106] In addition, the structure of the second contact part 2, combined with the structure of the first contact part 1, enables the oral endoscope lens 101 to successfully capture images of the sides of the teeth and the sides of the gums.

[0107] When the oral endoscope 10 is working, the second contact surface 22 slides along the tooth side and / or gum side. In one embodiment, the first contact surface 12 is also provided with a rolling structure such as a roller or ball to reduce the friction between the second contact surface 22 and the tooth side and / or gum side, thereby improving the user experience.

[0108] In one embodiment, please refer to Figures 6-7 Because the second contact surface 22 slides along the tooth side and / or gingival side when the oral endoscope 10 is working, the thickness of the second contact surface 22 should not be set too thin to avoid excessive pressure on the tooth side or gingival side. In one embodiment, please refer to... Figures 6-7 The thickness D4 of the second contact surface 22 is greater than 2 mm but less than 5 mm. The second contact surface 22 should not be set too thick to avoid the contact surface being suspended when in contact with the tooth side and / or gum side, which would lead to unstable contact.

[0109] In one embodiment, please refer to Figures 6-7 The width D3 of the second contact surface 22 is adapted to the endoscope lens 101 to ensure sufficient support for the endoscope 10 while avoiding interference or obstruction to the smooth imaging of the endoscope 10.

[0110] In one embodiment, both the first contact portion 1 and the second contact portion 2 are made of a smooth and elastic material, such as silicone, thermoplastic silicone elastomer, or polyurethane. The fact that both the first contact portion 1 and the second contact portion 2 are made of a smooth and elastic material improves patient comfort when they come into contact with the oral cavity, and ensures that they maintain good contact, thereby limiting the distance between the intraoral endoscope lens 101 and the imaging area, and the degrees of freedom of movement of the intraoral endoscope 10.

[0111] The first contact part 1 is made of a smooth and elastic material, so that after the first contact part 1 comes into contact with the first area, it can maintain a good contact state with the first area and maintain a sufficient contact area. When the first contact part 1 moves on the first area, the first contact part 1 will not slip, so that the intraoral endoscope lens 101 moves stably and smoothly.

[0112] The second contact portion 2 is made of a smooth and elastic material, which allows the second contact portion 2 to maintain good contact with the second area after contacting it, and maintain a sufficient contact area. The two second contact portions 2 are arranged opposite each other and are located on both sides of the teeth or gums. The two second contact portions 2 have a certain clamping force on the teeth or gums. The second contact portion 2 made of elastic material can ensure effective clamping of the teeth or gums without causing damage to the teeth or gums, thus improving the user's comfort.

[0113] In one embodiment, please refer to Figure 9 and Figure 10 The spatial positioning structure also includes a mounting part 3. The first contact part 1 and the second contact part 2 are both fixedly mounted to the mounting part 3. The mounting part 3 is separately disposed from the intraoral endoscope lens 101. The intraoral endoscope lens 101 is mounted on the intraoral endoscope 10. The mounting part 3 is detachably fixed to the intraoral endoscope lens 101. That is, the spatial positioning structure is detachably disposed and is mounted on the intraoral endoscope 10 as an additional component of the intraoral endoscope 10.

[0114] In this embodiment, the spatial positioning structure is installed on the oral endoscope 10 as an additional component, allowing it to be mounted on a specific oral endoscope lens as needed. Installing this spatial positioning structure on the oral endoscope 10 enables existing oral endoscopes to be converted into stable imaging tools at minimal cost.

[0115] In one embodiment, the mounting part 3 is detachably fixed to the intraoral endoscope lens 101, generally by means of a sleeve connection. That is, a mounting groove is provided on the mounting part 3, and when the mounting part 3 is installed on the intraoral endoscope 10, it is sleeved on the intraoral endoscope 10 through the mounting groove, and the mounting groove and the intraoral endoscope 10 are tightly fitted, so that the spatial positioning structure and the intraoral endoscope 10 are detachably fixed. In some embodiments, the mounting part 3 and the intraoral endoscope 10 can also be detachably fixed by means of threaded connection, snap-fit, etc.

[0116] In one embodiment, the mounting part 3 is detachably fixed to the intraoral endoscope lens 101. Generally, the intraoral endoscope lens 101 is fixed to the intraoral endoscope 10. An avoidance hole 31 is provided on the mounting part 3 to avoid the intraoral endoscope lens 101 on the intraoral endoscope 10. After the mounting part 3 is installed on the intraoral endoscope 10, the intraoral endoscope lens 101 takes pictures of the imaging position through the avoidance hole 31.

[0117] In one embodiment, please refer to Figure 11 and Figure 12 The spatial positioning structure also includes a mounting part 3. The first contact part 1 and the second contact part 2 are both fixedly mounted to the mounting part 3. The mounting part 3 is integrally set with the oral endoscope lens 101. The oral endoscope lens 101 and the mounting part 3 are integrally set, that is, the oral endoscope lens 101 and the spatial positioning structure are integrally set. In this way, when performing oral examinations or imaging, this spatial positioning structure can be installed on the oral endoscope 10.

[0118] In this embodiment, the mounting part 3 is integrated with the intraoral endoscope lens 101. That is, during the production of the intraoral endoscope auxiliary instrument 20, different intraoral endoscope lenses 101 are matched with intraoral endoscope auxiliary instruments 20 of different sizes or models. When examining or taking pictures of different oral cavities, the appropriate intraoral endoscope auxiliary instrument 20 can be installed on the intraoral endoscope.

[0119] In one embodiment, please refer to Figure 13 The oral endoscope auxiliary device 20 also includes a lens module 4, which is located at the front of the oral endoscope lens 101.

[0120] Lens module 4 is installed at the front of the intraoral endoscope lens 101 and is used to adjust the focal length of the intraoral endoscope lens 101, changing its optical parameters to better suit the needs of oral observation. For example, many traditional intraoral endoscopes 10 have a small field of view (FOV) and a long focal length, making it difficult to achieve detailed close-up observation, especially in the posterior tooth region, where a comprehensive observation is often impossible. In this embodiment, by setting a lens module 4 at the front of the intraoral endoscope lens 101 and adjusting the focal length of the original intraoral endoscope lens 101 using the lens module 4, this intraoral endoscope 10 can be adapted to more flexible oral examination scenarios.

[0121] In one embodiment, the lens module 4 and the oral endoscope aid 20 are designed as an integrated structure, and the type and parameters of the lens module 4 are clearly marked. When the user needs to replace the lens module 4, this can be achieved by replacing the entire oral endoscope aid 20. This design makes the maintenance and replacement of the oral endoscope aid 20 much simpler.

[0122] If the mounting part 3 is detachably fixed to the intraoral endoscope lens 101, then the lens module 4 is fixed to the mounting part 3. When the mounting part 3 and the intraoral endoscope lens 101 are fixed relative to each other, the lens module 4 is fixed in front of the intraoral endoscope lens 101.

[0123] If the mounting part 3 is integrated with the oral endoscope lens 101, then the lens module 4 is fixedly mounted in front of the oral endoscope lens 101 fixed on the mounting part 3, that is, the lens module 4 is fixedly integrated with the mounting part 3.

[0124] In another embodiment, the lens module 4 and the oral endoscope auxiliary instrument 20 are designed as separate units, allowing the user to manually replace the lens module 4 according to different needs. The lens module 4 and the oral endoscope auxiliary instrument 20 are connected separately using a snap-fit ​​or threaded structure.

[0125] The lens module 4 and the oral endoscope auxiliary device 20 adopt a separate design. After the oral endoscope auxiliary device 20 and the oral endoscope lens 101 are fixed, the lens module 4 is fixed to the oral endoscope auxiliary device 20, and the lens module 4 is placed in front of the oral endoscope lens 101. Alternatively, the lens module 4 can be connected to the front of the oral endoscope lens 101 on the oral endoscope 10 auxiliary device. Or, the lens module 4 can be directly connected to the front of the oral endoscope lens 101 mounted on the oral endoscope 10. When using the oral endoscope 10, the user can also flexibly adjust the focal length and field of view of the oral endoscope lens 101 by replacing different types of lens modules 4, thereby meeting the needs of different oral examination scenarios.

[0126] In one embodiment, the lens module 4 can also be adjustable. The lens module 4 is directly integrated with the existing main lens of the oral endoscope 10 using a sliding or rotating mechanism, enabling adjustment of the overall focal length of the main lens of the oral endoscope 10 and the lens module 4. This embodiment allows the main lens of the oral endoscope 10 to achieve clear imaging at closer distances through focal length adjustment, meeting the observation needs of different oral cavity areas.

[0127] In one embodiment, the lens module 4 consists of lens assemblies with different refractive indices and radii of curvature. By changing the relative position or angle of these lenses, the focal length and field of view (FOV) can be flexibly adjusted. This design ensures clear imaging in different oral cavity regions (such as the posterior tooth region), avoiding the problem that existing oral endoscopes 10 cannot meet clinical needs due to excessively long focal lengths or excessively small field of view.

[0128] In one embodiment, please refer to Figures 14-16 The oral endoscope auxiliary device 20 also includes a second lens 5, and the number of second lenses 5 is one, two or more. The second lens 5 may have the same or different shooting area as the oral endoscope lens 101, and the second lens 5 and the oral endoscope lens 101 may have the same or different shooting angles for the same shooting area.

[0129] In this embodiment, based on the existing oral endoscope lens 101, an additional lens (second lens 5) is further equipped on the oral endoscope 10, resulting in one or more additional second lenses 5 on top of the original oral endoscope lens 101. The second lens 5 may have the same or different shooting area as the oral endoscope lens 101, and the shooting angle of the second lens 5 and the oral endoscope lens 101 for the same shooting area may be the same or different. This embodiment enables the oral endoscope 10 to capture the same scene using multiple cameras, acquiring image data from different angles, or capturing the same area multiple times from the same angle. By comparing the differences between two images, the system can use a stereo matching algorithm to calculate the depth information of each pixel, thereby obtaining the three-dimensional structure of the scene.

[0130] In one embodiment, please refer to Figure 14 In this embodiment, the second lens 5 captures images of the occlusal surface of the teeth, while the intraoral endoscope lens 101 captures images of the lateral surface of the teeth or the lateral surface of the gums. This embodiment allows for simultaneous imaging of the occlusal surface of the teeth and one lateral surface of the teeth or one lateral surface of the gums, improving imaging efficiency and speed.

[0131] In one embodiment, please refer to Figure 15In this embodiment, the imaging area of ​​the oral endoscope lens 101 is the occlusal surface of the teeth, and the imaging area of ​​the second lens 5 is also the occlusal surface of the teeth. The oral endoscope lens 101 and the second lens 5 capture images of the same area of ​​the occlusal surface of the teeth sequentially. Capturing the same area twice in this embodiment improves the completeness of the imaging of the area, and the images obtained from the two captures can be compared and combined.

[0132] In one embodiment, please refer to Figure 16 In this embodiment, the imaging area of ​​the oral endoscope lens 101 is the side of the teeth and / or the side of the gums. Two second lenses 5 are provided, and the imaging area of ​​both second lenses 5 is the occlusal surface of the teeth. This embodiment can realize simultaneous imaging of the occlusal surface of the teeth and one side of the teeth or one side of the gums, improving imaging efficiency and speed.

[0133] In some embodiments, the oral endoscope lens 101 and the second lens 5 can simultaneously capture images of the same area, but at different angles.

[0134] In one embodiment, please refer to Figure 17 The oral endoscope aid 20 also includes a supplementary light 6 and a portable power source. The portable power source powers at least the supplementary light 6. Both the supplementary light 6 and the portable power source are fixedly installed with the oral endoscope aid 20.

[0135] In this embodiment, a supplementary light 6 is provided to solve the imaging quality problem caused by insufficient light source in the existing oral endoscope 10. The supplementary light 6 can not only effectively enhance the imaging brightness, but also improve the working performance of the oral endoscope 10 under certain special circumstances. Specific technical details are as follows: Oral endoscopes 10 often suffer from insufficient brightness of their built-in light source due to prolonged use, or problems such as bulb decay or damage, failing to provide adequate illumination. Therefore, this embodiment incorporates a supplementary light 6 to supplement the light source, ensuring stable brightness in the imaging area, thereby improving image quality and preventing image blurring or loss of detail due to insufficient light.

[0136] When an external lens (such as a zoom lens, close-up lens, lens module 4, etc.) is added to a traditional oral endoscope lens 101 to adjust the focal length or field of view, the original optical properties of the oral endoscope will be changed. This change may result in insufficient brightness in the field of view, so an additional supplementary light 6 is required to provide sufficient light source support to ensure a clear and bright image, suitable for use in various oral observation scenarios.

[0137] To ensure optimal imaging results, the LEDs in the supplementary light 6 are preferably equipped with color temperature control, with the color temperature maintained at around 6500K. A color temperature of 6500K is close to natural light, providing a light source with high color rendering, ensuring clearer and more realistic image details during oral examinations, and avoiding color cast. Color temperature control also reduces the impact of different light sources on image colors, avoiding image distortion caused by excessively cool or warm light sources.

[0138] In one embodiment, the supplemental light 6 also has an ultraviolet light mode. Switching to ultraviolet light mode is suitable for specific oral examinations, such as observing dental plaque. Ultraviolet light can stimulate bacteria and minerals on the tooth surface, helping dentists identify the distribution of dental plaque and thus providing a more accurate oral hygiene assessment. Through this mode, dentists can obtain more data helpful in assessing dental health beyond routine examinations.

[0139] In one embodiment, the supplementary light 6 also has an infrared light mode. Switching to infrared light mode is particularly suitable for imaging and observing problems such as tooth cracks and cavities in teeth. Infrared light has penetrating power, capable of penetrating thin layers of hard tissue (such as tooth enamel) to reveal the fine internal structure of teeth, such as microcracks and potential cavities, which are typically difficult to observe under ordinary visible light. Through infrared mode, the oral endoscope can obtain more in-depth diagnostic information, helping doctors make more accurate treatment decisions.

[0140] It is worth noting that when the supplementary light 6 is in ultraviolet or infrared light mode, the lens in front of the oral endoscope lens 101 requires special optical coating treatment. Specifically, the lens surface should be coated with double-pass (double-layer) or three or more layers of optical coating. These special coating materials can effectively separate light of different wavelengths, ensuring that special spectra such as ultraviolet and infrared light can be effectively transmitted through the lens, while blocking unnecessary stray or reflected light, thus ensuring the quality of the final image.

[0141] Dual-pass coating: mainly used to separate ultraviolet and visible light components, reduce the reflection and scattering of ultraviolet light, improve the transmittance of ultraviolet light, and at the same time avoid the influence on ordinary visible light.

[0142] Three-way coating: Suitable for imaging needs that simultaneously process infrared and ultraviolet light, providing more efficient spectral transmission capability while controlling light reflection and scattering to ensure that image quality is not compromised.

[0143] In one embodiment, the oral endoscope aid 20 further includes a distance sensor integrated into the oral endoscope aid 20 for real-time measurement of the distance between the oral endoscope and the target object. The distance sensor accurately senses the distance information of the target in a non-contact manner and feeds it back to the control system of the oral endoscope. The system can automatically adjust the focal length based on the measurement results to ensure that the image remains clear at different shooting distances. This function is particularly suitable for detailed observation of oral structures, avoiding focal length distortion caused by changes in distance. Distance sensors include, but are not limited to, TOF and laser sensors.

[0144] In one embodiment, the oral endoscope aid 20 further includes an added speckle emitter and receiver. The speckle sensor can monitor and analyze changes in the speckle pattern, assisting in the measurement of deformation or displacement of the imaging surface. By capturing the optical speckle effect, the speckle sensor can even further assist in the three-dimensional reconstruction of oral images, forming a digital three-dimensional oral model.
