Description

Technical Field

[0001] This invention relates to dental imaging technology, and more specifically to a dental imaging multi-angle scanner. Background Technology

[0002] Dentistry primarily treats diseases related to teeth and periodontium, including dental caries, pulpitis, periapical periodontitis, and non-carious hard tissue diseases. Scanners are often used in dental treatments; traditional scanning equipment is typically handheld and used to scan the inside of the patient's mouth.

[0003] Chinese invention patent CN202111001626.0 discloses a dental imaging scanner and its information cloud management system. This dental imaging scanner and its information cloud management system scan the inside of a patient's mouth using a scanning component within a housing, acquiring images of the patient's oral cavity. An adjustment component allows the housing to rotate on a support, thereby adjusting the position of the scanning component inside the patient's mouth. A rotating component drives the mounting platform to rotate, enabling left and right rotation adjustment of the entire device. This facilitates a comprehensive scan of the patient's oral cavity, providing a complete understanding of the patient's dental symptoms and enabling precise dental treatment.

[0004] Existing devices require patients to bite down on the occlusal blocks, which can easily slip or fall off, and prolonged biting can lead to patient fatigue. Furthermore, this structure relies solely on the contact and fixation of the occlusal surfaces of the upper and lower teeth, making it unsuitable for different patients' dental arch morphologies or varying oral opening degrees, severely limiting its applicability. Additionally, the probe positions of existing devices are relatively fixed, with a single scanning angle, making it difficult to acquire multi-angle images of the same area. This necessitates separate placement of the probes for each jaw, preventing the simultaneous acquisition of images covering both jaws under the same physiological occlusal state. This not only reduces examination efficiency but also introduces spatial registration errors in the jaw images due to patient movement, hindering accurate occlusal relationship analysis. Therefore, a multi-angle dental imaging scanner was developed. Summary of the Invention

[0013] As a further optimization of the present invention, a slider is slidably fitted into the inner wall of the adjusting groove, and the end of the adjusting rod is engaged with the end of the slider;

[0014] The two ends of the slider are engaged with the lower end of the movable block, and the outer surface of the movable block is provided with a through hole, the inner wall of the through hole being rotatably connected to the outer surface of the sphere.

[0016] Both ends of the connecting rod are provided with connecting grooves, and the inner wall of the connecting groove is slidably connected to the outer surface of the end of the connecting block.

At the same time, a docking block is fixedly provided at the end of the extension plate, and the inner wall of the docking block is fitted and slidably connected to the outer surface of the protective block.

[0018] As a further optimization of the present invention, the upper end of the extension plate is rotatably provided with a rotating shaft, and the outer surface of the rotating shaft meshes with the outer surface of the extension block. A protective ring is sleeved on the outer surface of the rotating shaft, and the inner wall of the protective ring is in contact with the outer surface of the end of the protective block.

[0019] As a further optimization of the present invention, a ring is slidably provided at the end of the locking block, and a limiting groove is provided through the outer surface of the ring.

[0020] As a further optimization of the present invention, a positioning groove is provided on the side of the ring near the locking block, and the inner wall of the positioning groove is slidably connected to the outer surface of the extension plate.

[0021] As a further optimization of the present invention, a limiting block is snapped onto the outer surface of the protective rod, and a limiting rod is snapped onto the end of the limiting block, wherein the outer surface of the limiting rod is slidably connected to the inner wall of the limiting groove.

[0022] As a further optimization of the present invention, a limiting plate is fixedly provided at the end of the limiting rod, and the inner wall of the limiting plate is slidably connected to the outer surface of the ring.

[0023] Compared with the prior art, the dental imaging multi-angle scanner provided by the present invention has the following beneficial effects:

[0024] By setting up movable components, the opening size and arch shape of the movable plate can be flexibly adjusted according to the patient's actual mouth opening degree and dental arch shape, adapting to the oral conditions of different patients; avoiding the problems of traditional occlusal structures requiring patients to bite down for a long time, easily slipping and falling off, and causing patient fatigue, effectively improving the patient's comfort during use and the stability of the structural fit.

[0025] By setting up the detection components, the angle and position of the two trays can be flexibly adjusted, enabling multi-angle scanning while adapting to different patients' oral morphologies. It can simultaneously acquire images of the upper and lower occlusal ends in the same occlusal state without the need to place the detectors for shooting in multiple stages. This not only improves examination efficiency but also avoids spatial registration errors in the images of the upper and lower jaws caused by multiple patient movements, providing more reliable image data support for accurate occlusal relationship analysis.

[0026] Through the coordinated action of the moving and detection components, the angle and position of the detection component tray can be adjusted simultaneously while adjusting the size and curvature of the moving plate opening to suit the patient's oral condition. This eliminates the need for multiple separate adjustments, simplifies the pre-scan preparation process, and further enhances the ease of use and examination efficiency of the equipment. The overall structural design is tailored to the actual needs of dental clinical use, making it more adaptable and practical. Attached Figure Description

[0038] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0039] Example: Please refer to Figure 1 - Figure 8 A dental imaging multi-angle scanner includes a frame body 1, and a movable plate 11 is snapped onto the side of the frame body 1.

[0040] In this solution, a support plate 12 is snapped onto the side of the main body 1 of the frame to support the patient. The patient's mandible is placed on the surface of the support plate 12 for initial positioning. The movable plate 11 can slide vertically along the side wall of the main body 1 of the frame to adapt to the bite height requirements of different patients.

[0041] Furthermore, the movable component 2, which is assembled at the lower end of the movable plate 11, includes a movable plate 21, a movable block 27, a connecting rod 25, and a ball 251; the inner wall of the movable plate 21 is engaged with the end of the movable block 27, the inner cavity of the movable block 27 is rotatably connected to the outer surface of the ball 251, and the outer surface of the ball 251 is connected to the end of the connecting rod 25. When the connecting rod 25 is subjected to force, it works with the ball 251 to drive the movable block 27 to move, squeezing the movable plate 21, thereby adjusting the opening size and arc degree of the movable plate 21.

[0042] In this embodiment, the movable plate 21 is an elastically deformable arc-shaped structure. In the initial state, it maintains a preset opening width. When the ball 251 is subjected to the force transmitted by the connecting rod 25, it drives the movable blocks 27 on both sides to move towards or away from each other along the inner wall of the movable plate 21. When moving towards each other, the movable blocks 27 squeeze the inner side of the movable plate 21, causing the movable plate 21 to expand outward and increase the opening width to accommodate a larger oral opening for the patient. When moving away from each other, the movable blocks 27 stretch the inner side of the movable plate 21, reducing the opening width to accommodate a smaller oral opening for the patient. At the same time, the overall arc curvature of the movable plate 21 is adjusted to match the different dental arch shapes of different patients, ensuring that it can fit stably after being placed in the patient's oral cavity and will not easily shift.

[0043] Furthermore, the movable component 2 also includes a snap-fit ​​plate 22 that snaps into the movable plate 21. A snap-fit ​​rod 221 is fixedly provided at the end of the snap-fit ​​plate 22. An adjustment block 23 is slidably provided at the end of the snap-fit ​​rod 221. An adjustment groove 231 is provided at the end of the adjustment block 23, and an adjustment rod 232 is fixedly provided on the inner wall of the adjustment groove 231.

[0044] Specifically, the snap-fit ​​plate 22 is fixed to the inner midpoint of the movable plate 21 via a snap-fit ​​structure, providing stable installation support for the snap-fit ​​rod 221. The snap-fit ​​rod 221 extends horizontally and works with the adjusting block 23 to stably guide the movement of the movable block 27, preventing structural displacement during adjustment. The snap-fit ​​rod 221 is a screw, and the inner cavity of the adjusting block 23 has a matching threaded groove. Rotating the adjusting block 23 will cause it to move axially along the snap-fit ​​rod 221, thereby achieving precise adjustment of the position of the adjusting block 23.

[0045] Furthermore, a slider 26 is slidably fitted into the inner wall of the adjusting groove 231, and the end of the adjusting rod 232 is engaged with the end of the slider 26; both ends of the slider 26 are engaged with the lower end of the movable block 27, and a through hole 271 is opened on the outer surface of the movable block 27, and the inner wall of the through hole 271 is rotatably connected to the outer surface of the ball 251.

[0046] Specifically, the slider 26 is slidably disposed on the inner wall of the adjustment groove 231 to achieve adaptive buffering in the vertical direction and avoid jamming during structural adjustment. When the adjustment block 23 moves along the axial direction of the locking rod 221, the slider 26 moves synchronously through the adjustment rod 232, which in turn drives the movable blocks 27 connected to both ends of the slider 26 to move synchronously, ensuring that the movement amplitude of the movable blocks 27 on both sides is consistent and avoiding the problem of asymmetrical deformation of the movable plate 21 on both sides.

[0047] The adjusting rod 232 is an elastic telescopic component that can provide adaptive buffer margin during the movement of the slider 26, avoiding structural wear and jamming caused by rigid pushing.

[0048] Furthermore, telescopic members 24 are symmetrically slidably provided at the ends of the movable plate 21, and connecting blocks 241 are snapped onto the ends of the telescopic members 24; connecting grooves 252 are provided at both ends of the connecting rod 25, and the inner wall of the connecting groove 252 is slidably connected to the outer surface of the end of the connecting block 241.

[0049] Specifically, when the opening width of the movable plate 21 is adjusted, the end will be displaced synchronously, causing the telescopic component 24 to slide along the end of the movable plate 21. The connecting block 241 at the end of the telescopic component 24 slides in conjunction with the connecting groove 252 at both ends of the connecting rod 25, thus maintaining a stable connection between the connecting rod 25 and the end of the movable plate 21, and preventing connection failure due to deformation of the movable plate 21.

[0050] Meanwhile, the telescopic component 24 is a component with telescopic function, used to adjust the height difference of the connecting block 241, adapt to the position change of the connecting rod 25 in the vertical direction, always ensure stable force transmission, avoid the situation of force jamming, and ensure smooth opening amplitude adjustment process.

[0051] Furthermore, the detection component 3, which is assembled on the inner wall of the movable plate 21, includes a protective block 33, a protective rod 332, and a tray 36; the inner wall of the protective block 33 is rotatably connected to the outer surface of the protective rod 332, and both ends of the protective rod 332 are snapped with trays 36, so that when the protective rod 332 is rotated under force, it simultaneously drives the tray 36 to rotate, adjusting the position of the tray to simultaneously acquire images of the upper and lower biting ends from multiple angles.

[0052] In this embodiment, the protective block 33 is installed on the inner side of the movable plate 21. The protective rod 332 is installed through the protective block 33 and can rotate flexibly around its own axis. The two trays 36 are respectively installed at the two ends of the protective rod 332 that extend out of the protective block 33. The upper tray corresponds to the patient's maxillary occlusal end, and the lower tray corresponds to the patient's mandibular occlusal end. Both trays 36 have built-in dental image acquisition and detection units.

[0053] When the protective rod 332 is rotated, the two trays 36 rotate synchronously with the protective rod 332, which facilitates the adjustment of the detection and acquisition angle. During the process of the patient clenching and maintaining a fixed physiological occlusion, the upper and lower occlusal ends are simultaneously acquired from multiple angles. This eliminates the need to take images of the upper and lower jaws in separate sessions, which improves detection efficiency and avoids spatial registration errors caused by the patient's body position movement during separate shooting.

[0054] Furthermore, the detection component 3 also includes a locking block 31 that engages with the movable plate 21. An extension plate 32 is fixedly provided at the end of the locking block 31. An extension block 321 is slidably provided on the side of the extension plate 32. At the same time, a docking block 323 is fixedly provided at the end of the extension plate 32. The inner wall of the docking block 323 is fitted and slidably connected to the outer surface of the protective block 33.

[0055] Specifically, the locking block 31 is fixed to the inner wall of the movable plate 21 by a snap-fit ​​structure, providing stable installation support for the extension plate 32. By adjusting the extension length of the extension plate 32, the protective block 33 is moved along the docking block 323, thereby adjusting the position of the detection component 3 in the oral cavity to adapt to the differences in oral cavity depth of different patients and ensure that the tray 36 can be accurately moved to the occlusal area to be scanned.

[0056] Furthermore, a rotating shaft 322 is rotatably provided at the upper end of the extension plate 32, and the outer surface of the rotating shaft 322 meshes with the outer surface of the extension block 321. A protective ring 331 is sleeved on the outer surface of the rotating shaft 322, and the inner wall of the protective ring 331 is in contact with the outer surface of the end of the protective block 33.

[0057] Specifically, the side of the extension plate 32 is provided with a sliding groove that matches the extension block 321. When the extension block 321 moves, it drives the rotating shaft 322 to rotate. The surface of the rotating shaft 322 is in contact with the end of the protective block 33 through the protective ring 331, thereby synchronously driving the protective block 33 to rotate along the inner wall of the mating block 323. This adjusts the overall deflection angle of the protective block 33, thereby further fine-tuning the acquisition angle of the tray 36 to adapt to the scanning requirements of different interlocking areas, ensuring that the image acquisition can cover the area to be detected and avoiding scanning blind spots. The end of the extension block 321 can be driven by an externally connected electric telescopic rod.

[0058] Furthermore, a ring 37 is slidably provided at the end of the locking block 31, and a limiting groove 371 is provided through the outer surface of the ring 37. A positioning groove 372 is provided on the side of the ring 37 near the locking block 31, and the inner wall of the positioning groove 372 is slidably connected to the outer surface of the extension plate 32.

[0059] Specifically, when the ring 37 slides along the end of the locking block 31, the positioning groove 372 and the extension plate 32 maintain the sliding guide at all times, so as to avoid the ring 37 from deflecting or misaligning during the sliding process and ensure the stability of the position adjustment.

[0060] Furthermore, a limiting block 34 is snapped onto the outer surface of the protective rod 332, and a limiting rod 35 is snapped onto the end of the limiting block 34. The outer surface of the limiting rod 35 is slidably connected to the inner wall of the limiting groove 371.

[0061] Specifically, the limiting block 34 is fixed to one end of the protective rod 332 that extends out of the protective block 33. During the process of the protective rod 332 rotating to adjust the angle of the tray 36, the limiting rod 35 moves synchronously with the limiting block 34 and slides along the inner wall of the limiting groove 371 on the surface of the ring 37, providing stable guidance and limiting for the rotation of the protective rod 332, avoiding axial movement during the rotation of the protective rod 332, and ensuring the accuracy of the angle adjustment.

[0062] When the ring 37 is adjusted up and down, it drives the limiting rod 35 to move synchronously, which in turn drives the protective rod 332 to rotate in conjunction with the limiting block 34. There is no need to manually rotate the protective rod 332 to adjust the angle. The angle of the protective rod 332 and the tray 36 can be automatically adjusted synchronously simply by moving the position of the ring 37. This simplifies the angle adjustment operation process and makes the adjustment process more convenient and smooth. The ring 37 and the locking block 31 can be driven by an externally connected electric telescopic rod, and the above-mentioned control components are synchronously connected to the external control device.

[0063] Furthermore, a limiting plate 351 is fixedly provided at the end of the limiting rod 35, and the inner wall of the limiting plate 351 is slidably connected to the outer surface of the ring 37.

[0064] Specifically, the limiting plate 351 is in close contact with the outer surface of the ring 37, which can axially limit the sliding stroke of the limiting rod 35, prevent the limiting rod 35 from coming out of the limiting groove 371 during the sliding process, ensure that the structural connection is always stable, and prevent the structural failure during the adjustment process.

[0065] The control device can choose a microcontroller as the control terminal. In this embodiment, the microcontroller is a typical embedded microcontroller unit, consisting of an arithmetic logic unit (ALU), a controller, memory, input / output devices, etc., essentially a miniature computer. Compared to general-purpose microprocessors used in personal computers, it emphasizes self-sufficiency (no external hardware required) and cost savings. Its biggest advantage is its small size, allowing it to be placed inside the instrument, but it has limited storage capacity, simple input / output interfaces, and low power consumption.

[0066] Working principle: When in use, first adjust the opening range and arch curvature of the movable plate 21 according to the patient's oral cavity opening and dental arch shape: rotate the adjusting block 23 to move it along the axial direction of the locking rod 221, drive the slider 26 to move synchronously, and then drive the two movable blocks 27 on both sides to move towards or away from each other along the inner wall of the movable plate 21, squeeze or stretch the elastic arc-shaped movable plate 21, change its opening range and arch curvature, and adapt to the patient's current oral condition.

[0067] After adjustment, the movable plate 21 is inserted into the patient's mouth, allowing the patient to maintain a fixed physiological state by biting lightly. The device can be stably positioned without the patient having to bite the bite block for a long time. It will not slip or fall off, nor will it cause bite fatigue in the patient.

[0068] After positioning is completed, the overall position of the detection component 3 is adjusted according to the depth of the patient's oral cavity. The extension plate 32 is pulled to adjust the extension length, which drives the protective block 33 to move along the docking block 323. The trays 36 with the two built-in detection units are sent to the corresponding positions of the upper and lower jaw occlusal ends, and then the collection angle of the trays 36 is adjusted.

[0069] The electric telescopic rod drives the ring 37 to slide vertically along the end of the locking block 31. The ring 37 drives the limiting rod 35 to move synchronously through the limiting groove 371, which in turn drives the limiting block 34 to rotate the protective rod 332, causing the two trays 36 to deflect synchronously. This allows for the simultaneous acquisition of multi-angle images of the upper and lower jaw occlusion areas while the patient maintains the same physiological occlusion state.

[0070] If further fine-tuning of the scanning angle is required for a local area, the extension block 321 can be driven to slide along the extension plate 32, causing the rotating shaft 322 to rotate. Through the protective ring 331, the protective block 33 is deflected as a whole, further correcting the acquisition angle of the tray 36, eliminating scanning blind spots, and ensuring complete and clear image acquisition.

[0071] The entire scanning process does not require taking images of the upper and lower jaws in separate sessions, which improves detection efficiency and avoids spatial registration errors caused by separate shooting, providing reliable image support for accurate occlusal relationship analysis.

[0072] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
