Description

Technical Field

[0001] This utility model relates to the field of oral X-ray imaging auxiliary device technology, specifically to a universal adjustable bracket assembly for intraoral X-ray sensors and an intraoral X-ray sensor kit. Background Technology

[0002] The statements in this section are merely background information related to this application and do not necessarily constitute prior art.

[0003] The intraoral X-ray sensor is the core component of a digital dental X-ray imaging system. During use, it is placed on the lingual side of the patient to capture localized images of the tooth structure, periodontal tissues, and periapical region. During imaging, a support assembly is needed to stably fix the sensor within the patient's mouth, while the patient bites down on the support assembly to keep the sensor in contact with the target tooth.

[0004] In the prior art, US 2002 / 0076002 A1 discloses a modular occlusal block and sensor holder device for dental X-ray examination. This device includes a guide arm, a multi-size adaptable aiming ring, and a modular occlusal block-sensor holder assembly. The sensor holder and occlusal block are detachably fixed through the insertion and engagement of a composite profile protrusion and a slot. Furthermore, the same holder can be used with occlusal blocks of various shapes and sizes to adapt to different radiographic scenarios such as root canal radiographs, wing radiographs, and anterior / posterior panoramic radiographs.

[0005] However, in the process of implementing this application, the applicant discovered that the above-mentioned prior art still has at least the following shortcomings: 1. The existing intraoral X-ray sensor holder does not have a signal line fixing structure. After the signal line of the intraoral X-ray sensor is led out from the tail of the sensor, it is easy to swing in the patient's mouth during the imaging process, which may interfere with the buccal mucosa, gums, and tongue, causing patient discomfort and nausea reflex, or even pulling the sensor and causing displacement, thus affecting the image quality.

[0006] 2. The occlusal blocks of this device are made of hard material, and the occlusal wings are relatively hard. When the patient bites, the teeth make direct hard contact with the hard occlusal surface. For patients with sensitive teeth, children, or periodontal disease, the pain sensation during biting is obvious, which affects the patient's cooperation during the examination.

[0007] 3. For different patients, the oral cavity and teeth conditions are different, and the size of each sensor is different. The existing height adjustment technology lacks universality, and the stroke range and adjustment method of the height adjustment mechanism are limited.

[0008] In view of this, how to solve the problems of signal lines easily interfering with the patient's oral cavity, the hard texture of the bite wings causing pain, and insufficient universal compatibility of the existing intraoral X-ray sensor brackets has become the research topic to be solved by this utility model. Utility Model Content

[0009] The purpose of this invention is to provide a universal adjustable bracket assembly for intraoral X-ray sensors and an intraoral X-ray sensor kit.

[0010] To achieve the above objectives, the first aspect of this utility model adopts the following technical solution: a universal adjustable bracket assembly for an intraoral X-ray sensor, comprising a clamping part and an occlusal part, wherein the clamping part is used to clamp the intraoral X-ray sensor, and the occlusal part is used for patient biting contact; the bracket assembly further comprises a bracket body, a slider, a wire clamp, and a rubber sleeve. The slider slides along the height direction of the bracket body, and the clamping part is disposed on the slider and the bracket body; The bracket body is provided with the wire clamp, which is used to fix the signal line of the intraoral X-ray sensor. The rubber sleeve covers the occlusal surface of the occlusal portion, and the rubber sleeve is positioned and connected to the main body of the bracket through a positioning structure.

[0011] The second aspect of this utility model adopts the following technical solution: an intraoral X-ray sensor kit, the intraoral X-ray sensor kit including an intraoral X-ray sensor and a universal adjustable bracket assembly for the intraoral X-ray sensor as described in the first aspect, the intraoral X-ray sensor being clamped and fixed by the clamping part of the bracket assembly, and the signal line of the intraoral X-ray sensor being fixed on the wire clamp of the bracket body.

[0012] The relevant contents of this application are explained as follows: In the above solution, by implementing the first aspect of the present invention, a slider is set on the main body of the support and it slides along the height direction of the main body. At the same time, a clamping part is set on the slider, and a wire clamp for fixing the signal line and a rubber sleeve covering the occlusal surface of the occlusal part are set on the main body of the support. The sliding pair between the slider and the main body of the support converts the clamping position of the clamping part and the sensor into a movable structure that can be continuously adjusted along the height direction. This allows the support assembly to adapt to different patients' dental arch shapes and different tooth height differences, thereby significantly improving the versatility of the support. The wire clamp applies mechanical constraint to the signal line led out by the sensor, so that the cable is fixed along the surface of the main body of the support and prevents it from swinging freely in the mouth. At the same time, the soft elastic material properties of the rubber sleeve are used to transform the direct contact between the teeth and the rigid support during occlusion into a soft contact with the elastic material. This invention addresses the problems in existing technologies, such as inconvenient sensor bracket height adjustment, poor adaptability to different patients and tooth positions leading to insufficient versatility, signal cable interference with soft tissues causing discomfort and image artifacts, and pain during biting caused by hard occlusal surfaces in patients with sensitive teeth. This application enables continuous height adjustment of the bracket via a sliding slider, allowing the same bracket component to adapt to differences in dental arch height and tooth position requirements among different patients, as well as to the needs of sensors of different sizes. Positioning can be completed without replacing the bracket or occlusal block, significantly improving clinical versatility. It also effectively eliminates the risk of signal cable interference with oral soft tissues, avoids sensor displacement due to cable traction, and improves imaging stability. Furthermore, it significantly alleviates pain during biting, improving examination comfort and patient cooperation.

[0013] In the above solution, by implementing the second aspect of the present invention, an intraoral X-ray sensor is combined with a support assembly that has height adaptive adjustment, cable management, and soft occlusion functions. The height of the sensor clamping is adjusted by sliding the slider of the support assembly, the signal line led out by the sensor is fixed by the wire clamp, and the occlusal part with a rubber sleeve is used for patient occlusion and fixation, thus completing the intraoral positioning of the sensor. This allows the sensor to obtain stable and reliable positioning support in the mouth and automatically adapt to the differences of different patients. It is also suitable for sensors of different sizes. The signal line is effectively managed and no longer interferes with the operation. The patient's occlusal experience is more comfortable, thereby greatly improving the efficiency and quality of digital dental X-ray image acquisition.

[0014] A further technical solution includes an elastic telescopic sleeve on the outside of the stent body and the slider. The portion of the elastic telescopic sleeve opposite to the slider is fitted around the outer periphery of the slider, and the portion of the elastic telescopic sleeve opposite to the stent body is fitted around the outer periphery of the stent body, thereby applying an elastic preload between the stent body and the slider. By implementing this solution, the elastic contraction characteristics of the elastic telescopic sleeve are utilized to simultaneously apply a continuous elastic restoring force to both the stent body and the slider in the radial direction. This drives the slider to automatically move downwards along the height direction, ensuring that the sensor always maintains a stable and gentle contact with the patient's tongue, further enhancing the universal adaptability of the stent assembly to different patients.

[0015] A further technical solution involves the elastic telescopic sleeve comprising a first fitting part, a second fitting part, and an elastic connecting part. The first fitting part is fitted onto the outer periphery of the upper portion of the slider, with the upper portion of the slider extending inward. The second fitting part is fitted onto the outer periphery of the lower portion of the support body, with the corresponding fitting position on the support body extending inward. The elastic connecting part connects the first and second fitting parts. This inward extension refers to the direction of extension towards the inside of the opening during use. During use, the elastic connecting part remains stretched and elastic, ensuring the slider always tends to move downward. Furthermore, when installing the elastic telescopic sleeve, the elastic connecting part is positioned on the outside of the support body, with the first and second fitting parts fitted on the inside, to ensure the elastic telescopic sleeve does not detach.

[0016] A further technical solution involves a guide groove extending along the height direction on the main body of the support, and a slider body that slides in conjunction with the guide groove on the slider. The cross-sections of the guide groove and the slider body are matched. By matching the cross-sectional shapes of the guide groove and the slider body, a precision-guided sliding pair is formed. The constraint effect of the groove wall on the slider body restricts the slider's displacement and deflection in the direction perpendicular to the sliding direction, preventing lateral offset or swaying of the slider during sliding. This avoids changes in the orientation of the clamped sensor, affecting the imaging angle and stability, further ensuring the repeatability of height adjustment and making the support's universal adjustment function more reliable. The cross-sectional shapes of the guide groove and the slider body can be elliptical, rectangular, or other elongated shapes.

[0017] A further technical solution includes a limiting groove on the inner wall of the guide groove, and a limiting cover plate at the opening of the guide groove; the slider is provided with a limiting block that slides with the limiting groove, and the limiting block, through its cooperation with the limiting groove and the limiting cover plate, limits the sliding stroke range of the slider within the guide groove. By embedding the limiting block into the limiting groove to form a stop boundary for the guide stroke, and simultaneously sealing the opening of the guide groove with the limiting cover plate, the sliding space of the slider is limited to a preset closed stroke range, effectively preventing the slider from coming off during assembly and use, and further ensuring the safety and reliability of the structural connection.

[0018] A further technical solution involves a flexible wire clamping groove located on the side of the bracket body. This groove has a narrow opening, through which the signal wire is pressed into the groove and radially clamped and fixed by the inner wall of the groove. This solution utilizes the elastic deformation capability of the groove wall to allow the signal wire to be pressed into the groove from the narrow opening for controllable and stable fixing. The operation is convenient and efficient, further ensuring the secure fixing of the signal wire and its long-term reliability.

[0019] A further technical solution involves aligning the length extension direction of the elastic cable retainer groove with the length extension direction of the occlusal surface on the occlusal region. The narrow opening of the elastic cable retainer groove faces upwards and gradually narrows upwards. This alignment of the cable retainer groove with the length extension direction of the occlusal surface, along with the upward opening facilitating the natural path of the signal cable after it exits the sensor, allows for better adaptation to the patient's mouth-opening motion when using an intraoral X-ray sensor. This further avoids signal cable interference or bending, and significantly improves the stability and comfort of the cable fixation.

[0020] A further technical solution includes a positioning structure comprising a positioning groove on the engagement portion and positioning blocks on the inner side of the rubber sleeve corresponding one-to-one with the positioning groove; the positioning blocks are embedded in the positioning grooves to fix the rubber sleeves to the bracket body. This solution utilizes the positioning structure formed by the positioning blocks embedded in the positioning grooves to achieve mechanical interlocking and fixing between the rubber sleeves and the bracket body, thereby firmly bonding the rubber sleeves and the bracket body. This ensures that the rubber sleeves remain stable and do not fall off even after long-term and repeated engagement and disengagement, and assembly requires no additional fasteners, resulting in precise positioning and simple processing and assembly.

[0021] A further technical solution involves providing two positioning grooves on the occlusal portion, one on the upper surface and the other on the lower surface. Correspondingly, two positioning blocks are provided on the inner side of the rubber sleeve, one on the upper surface and the other on the lower surface. This solution, by providing positioning points on both the upper and lower surfaces of the occlusal portion, significantly improves the positioning stability and anti-dislodgement capability of the rubber sleeve under complex biting forces, further ensuring a long-term tight fit between the rubber sleeve and the occlusal surface.

[0022] Due to the application of the above-mentioned solution, the technical solution of this application has the following advantages and effects compared with the prior art: 1. This utility model addresses the problems of existing intraoral X-ray sensor brackets, such as signal wires easily interfering with the patient's oral cavity, the hard texture of the bite wings causing pain, and insufficient universal adaptability. It innovatively designs a universal adjustable bracket assembly for intraoral X-ray sensors. This assembly allows for continuous height adjustment via a sliding slider, enabling the same bracket assembly to adapt to differences in dental arch height and tooth position requirements among different patients, as well as to the needs of sensors of different sizes. Positioning can be achieved without replacing the bracket or bite block, significantly improving clinical versatility. Simultaneously, it effectively eliminates the risk of signal wire interference with oral soft tissues, avoids sensor displacement due to cable traction, and improves imaging stability. Furthermore, it significantly alleviates pain during biting, improving examination comfort and patient cooperation.

[0023] 2. This utility model also innovatively designs an intraoral X-ray sensor kit. This intraoral X-ray sensor kit combines an intraoral X-ray sensor with a support assembly that has height adaptive adjustment, cable management, and soft occlusion functions. The slider of the support assembly adjusts the sensor clamping height, the cable clamp fixes the signal line led out by the sensor, and the occlusal part with a rubber sleeve is used for patient biting and fixation. This completes the intraoral positioning of the sensor, thereby enabling the sensor to obtain stable and reliable positioning support in the mouth and automatically adapt to different patients' different conditions. It is also suitable for sensors of different sizes. Moreover, the signal line is effectively managed and no longer interferes with the operation, making the patient's biting experience more comfortable, thus greatly improving the efficiency and quality of digital dental X-ray image acquisition.

[0032] The terminology used herein is for the purpose of describing specific embodiments only and is not intended to limit the scope of this work. Singular forms such as “a,” “this,” “this,” “the,” and “the” as used herein also include plural forms.

[0033] This application aims to solve the problems of existing intraoral X-ray sensor brackets, such as signal lines easily interfering with the patient's oral cavity, hard bite wings causing pain, and insufficient universal adaptability. In response, an innovative universal adjustable bracket assembly for intraoral X-ray sensors has been designed.

[0034] Example 1, as Figures 1 to 6 As shown, a universal adjustable bracket assembly for an intraoral X-ray sensor includes a clamping part 100 and an occlusal part 200. The clamping part 100 is used to clamp the intraoral X-ray sensor, and the occlusal part 200 is used for patient biting contact. The bracket assembly also includes a bracket body 1, a slider 2, a wire clamp 3, and a rubber sleeve 4. The slider 2 slides along the height direction of the support body 1, and the clamping part 100 is disposed on the slider 2 and the support body 1; The bracket body 1 is provided with the wire clamp 3, which is used to fix the signal line of the intraoral X-ray sensor; The rubber sleeve 4 covers the biting surface 210 of the biting part 200, and the rubber sleeve 4 is positioned and connected to the bracket body 1 through the positioning structure 5.

[0035] In Embodiment 1, a slider 2 is provided on the support body 1 and slidably engaged along the height direction of the support body 1. Simultaneously, a clamping part 100 is provided on the slider 2, and a wire clamp 3 for fixing the signal line and a rubber sleeve 4 covering the occlusal surface 210 of the occlusal part 200 are fixed on the support body 1 via a positioning structure 5. The sliding pair between the slider and the support body 1 converts the clamping position of the clamping part 100 and the sensor into a continuously adjustable movable structure along the height direction, enabling the support assembly to adapt to different patients' dental arch shapes and height differences in different tooth positions, thereby significantly improving the versatility of the support. The wire clamp 3 applies mechanical constraint to the signal line led out from the sensor, fixing the cable along the surface of the support body 1 and preventing it from swinging freely in the mouth. Simultaneously, the soft and elastic material properties of the rubber sleeve 4 transform the direct contact between the teeth and the rigid support during occlusion into a soft contact with the elastic material.

[0036] The implementation of Embodiment 1 of this application solves the problems in the prior art, such as inconvenient adjustment of sensor bracket height, poor adaptability between different patients and different tooth positions leading to insufficient versatility, interference between signal lines and soft tissues in the patient's mouth causing discomfort and image artifacts, and pain during biting caused by the hard occlusal surface 210 in patients with sensitive teeth. This application enables continuous adjustment of the bracket height through sliding, allowing the same bracket component to adapt to differences in dental arch height and different tooth positions in different patients, as well as to the needs of sensors of different sizes. Positioning can be completed without replacing the bracket or occlusal block, significantly improving clinical versatility. It also effectively eliminates the risk of signal line interference with oral soft tissues, avoids sensor displacement due to cable traction, and improves imaging stability; furthermore, it significantly alleviates pain during biting, improving examination comfort and cooperation.

[0037] In one embodiment of this application, such as Figure 1 , Figure 2 As shown, the stent assembly also includes an elastic telescopic sleeve 6, which is sleeved on the outside of the stent body 1 and the slider. The portion of the elastic telescopic sleeve 6 opposite to the slider is fitted around the outer periphery of the slider, and the portion of the elastic telescopic sleeve 6 opposite to the stent body 1 is fitted around the outer periphery of the stent body 1, so as to apply an elastic preload between the stent body 1 and the slider. By implementing this scheme, utilizing the elastic contraction characteristics of the elastic telescopic sleeve 6, the sleeve applies a continuous elastic restoring force to the stent body 1 and the slider simultaneously in the radial direction, thereby driving the slider to automatically move downwards in the height direction, so that the sensor always adheres to the patient's tongue side with a stable and gentle force, further enhancing the universal adaptability of the stent assembly to different patients and sensors of different sizes.

[0038] More specifically, such as Figure 2 , Figure 6As shown, the elastic telescopic sleeve 6 includes a first fitting part 61, a second fitting part 62, and an elastic connecting part 63. The first fitting part 61 is fitted onto the outer periphery of the upper part of the slider, which extends inward. The second fitting part 62 is fitted onto the outer periphery of the lower part of the support body 1, which extends inward at the corresponding fitting position. The elastic connecting part 63 connects the first fitting part 61 and the second fitting part 62. This inward extension refers to the direction of extension towards the opening in the usage state. In the usage state, the elastic connecting part 63 is always stretched and elastic, causing the slider to always have a tendency to move downward.

[0039] In addition, when installing the elastic telescopic sleeve 6, the elastic connecting part 63 is set on the outward side of the bracket body 1, and the first fitting part 61 and the second fitting part 62 are fitted on the inner side, so as to better ensure that the elastic telescopic sleeve 6 will not fall off.

[0040] In another embodiment of this application, such as Figure 3 , Figure 5 As shown, the support body 1 has a guide groove 11 extending along the height direction, and the slider has a slider body 21 that slides in conjunction with the guide groove 11; the cross-sections of the guide groove 11 and the slider body 21 are matched. By matching the cross-sectional shapes of the guide groove 11 and the slider body 21, a precision-guided sliding pair is formed. The constraint effect of the groove wall on the slider body 21 restricts the slider's displacement and deflection in the direction perpendicular to the sliding direction, thus preventing lateral offset or swaying of the slider during sliding, which could lead to changes in the orientation of the clamped sensor, affecting the imaging angle and stability. This further ensures the repeatability of height adjustment, making the support's universal adjustment function more reliable. The cross-sectional shapes of the guide groove 11 and the slider body 21 can be elliptical, rectangular, or other elongated shapes.

[0041] In another embodiment of this application, such as Figure 1 , Figure 3 As shown, a limiting groove 12 is provided on the inner wall of the guide groove 11, and a limiting cover plate 13 is provided at the opening of the guide groove 11. The slider is provided with a limiting block 22 that slides in cooperation with the limiting groove 12. The limiting block 22, through its cooperation with the limiting groove 12 and the limiting cover plate 13, limits the sliding stroke range of the slider within the guide groove 11. By embedding the limiting block 22 into the limiting groove 12, a stop boundary for the guide stroke is formed. At the same time, the limiting cover plate 13 covers the opening of the guide groove 11, blocking the exit path of the limiting block 22, thus limiting the sliding space of the slider within a preset closed stroke range. This effectively prevents the slider from coming out during assembly and use, further ensuring the safety and reliability of the structural connection.

[0042] In one embodiment of this application, such as Figure 1 , Figure 3 As shown, the wire clamp 3 is an elastic wire-locking groove 31 disposed on the side of the bracket body 1. The elastic wire-locking groove 31 has a narrow opening 32. The signal wire is pressed into the elastic wire-locking groove 31 through the narrow opening 32 and is radially clamped and fixed by the inner wall of the elastic wire-locking groove 31. This solution utilizes the elastic deformation capability of the wire-locking groove wall to press the signal wire into the elastic wire-locking groove 31 from the narrow opening 32 for controllable and stable fixation. The operation is convenient and efficient, further ensuring the firmness of the signal wire fixation and long-term reliability.

[0043] More specifically, such as Figure 1 , Figure 3 As shown, the length extension direction of the elastic wire-locking groove 31 is consistent with the length extension direction of the occlusal surface 210 on the occlusal part 200. The narrow opening 32 of the elastic wire-locking groove 31 faces upward and the opening gradually narrows upward. By aligning the direction of the wire-locking groove with the length extension direction of the occlusal surface 210 of the occlusal part 200, and utilizing the upward opening to follow the natural path of the signal line after it is led out from the sensor tail, this design can accommodate the patient's mouth-opening action when using the intraoral X-ray sensor, further avoiding signal line interference or bending, and further improving the stability and comfort of the cable fixation.

[0044] In another embodiment of this application, such as Figure 1 , Figure 4 As shown, the positioning structure 5 includes a positioning groove 7 disposed on the engagement part 200, and positioning blocks 41 disposed on the inner side of the rubber sleeve 4 corresponding one-to-one with the positioning groove 7; the positioning blocks 41 are embedded in the positioning groove 7 to fix the rubber sleeve 4 to the bracket body 1. This solution utilizes the positioning structure 5 formed by the positioning blocks 41 embedded in the positioning groove 7 to achieve mechanical interlocking and fixing between the rubber sleeve 4 and the bracket body 1, so as to firmly combine the rubber sleeve 4 and the bracket body 1, ensuring that the rubber sleeve 4 can maintain a stable position and not fall off after long-term and repeated engagement and use, and the assembly does not require additional fasteners, and the positioning is accurate and the processing and assembly are simple.

[0045] More specifically, the biting portion 200 is provided with two positioning grooves 7, one of which is located on the upper surface of the biting portion 200, and the other is located on the lower surface of the biting portion 200. Correspondingly, the inner side of the rubber sleeve 4 is provided with two positioning blocks 41, one of which is located on the upper surface of the inner side of the rubber sleeve 4, and the other is located on the lower surface of the inner side of the rubber sleeve 4. This design provides positioning points on the upper and lower surfaces of the biting portion 200, which significantly improves the positioning stability and anti-dislodgement ability of the rubber sleeve 4 under complex biting forces, and further ensures that the rubber sleeve 4 fits tightly against the biting surface 210 for a long time.

[0046] Example 2: This application discloses an intraoral X-ray sensor kit, which includes an intraoral X-ray sensor and a universal adjustable bracket assembly for the intraoral X-ray sensor as described in Example 1. The intraoral X-ray sensor is clamped and fixed by the clamping part 100 of the bracket assembly, and the signal line of the intraoral X-ray sensor is fixed on the wire clamp 3 of the bracket body 1.

[0047] Through the implementation of Embodiment 2 of this application, by combining an intraoral X-ray sensor with a support assembly having height adaptive adjustment, cable management, and soft occlusion functions, the sensor clamping height is adjusted by sliding the slider of the support assembly, the signal line led out from the sensor is fixed by the wire clamp 3, and the occlusal part 200 with the rubber sleeve 4 is used for patient occlusion and fixation, thus completing the intraoral positioning of the sensor. This allows the sensor to obtain stable and reliable positioning support in the mouth and automatically adapt to the differences of different patients. It is also suitable for sensors of different sizes. The signal line is effectively managed and no longer interferes with the operation. The patient's occlusal experience is more comfortable, thereby greatly improving the efficiency and quality of digital dental X-ray image acquisition.

[0048] The technical content of this application will now be described in detail with reference to a specific embodiment.

[0049] In this detailed embodiment, a universal adjustable bracket assembly for an intraoral X-ray sensor is provided, including a bracket body 1, a clamping part 100, an engaging part 200, a slider 2, an elastic telescopic sleeve 6, a wire clamp 3, and an adhesive sleeve 4.

[0050] The support body 1 is an L-shaped component with longitudinal and lateral extensions. A clamping part 100 is located on the longitudinally extending side of the support body 1 for clamping an intraoral X-ray sensor; an occlusal part 200 is located on the laterally extending side for patient occlusion. A slider is located at the upper end of the longitudinal extension, with one end of an elastic telescopic sleeve 6 sleeved with the slider and the other end connected to the lower end of the longitudinal extension, thus clamping the intraoral X-ray sensor. The slider slides along the height direction (i.e., longitudinally) of the support body 1, thereby adjusting the clamping height of the clamping part 100 and the sensor.

[0051] like Figure 3 As shown, the support body 1 has a guide groove 11 extending along the height direction. The slider 2 has a slider body 21 that slides in conjunction with the guide groove 11, and the cross-sections of the guide groove 11 and the slider body 21 match each other. Figure 3 (The middle part is rectangular) to ensure that the slider can only slide smoothly along the height direction and cannot disengage laterally from the guide groove 11.

[0052] like Figure 3 As shown, a limiting groove 12 is provided on the inner wall of the guide groove 11, and a limiting cover plate 13 is provided at the opening of the guide groove 11 (i.e., the upward end along the height direction). The slider 2 is also provided with a limiting block 22 that slides in cooperation with the limiting groove 12. The limiting block 22 is embedded in the limiting groove 12, and the limiting cover plate 13 closes the opening end of the guide groove 11. The two work together to restrict the limiting block 22 within the closed stroke range enclosed by the limiting groove 12 and the limiting cover plate 13 when the slider 2 slides, thereby preventing the slider from coming out of the guide groove 11 and limiting the effective adjustment stroke of the slider 2.

[0053] like Figure 6 As shown, the elastic telescopic sleeve 6 is an elastic tubular sleeve made of medical-grade silicone material. The elastic telescopic sleeve 6 includes a first fitting part 61, a second fitting part 62, and an elastic connecting part 63. Simultaneously, the upper end of the slider 2 extends inward to form a first extension part 23, and the corresponding fitting position of the support body 1 extends inward to form a second extension part 14. During assembly, the first fitting part 61 of the elastic telescopic sleeve 6 is fitted with the first extension part 23 at the upper end of the slider, and the second fitting part 62 of the elastic telescopic sleeve 6 is fitted with the second extension part 14 on the lower side of the support body 1. The elastic connecting part 63 of the elastic telescopic sleeve 6 is positioned opposite to the outside of the support body 1. Because the elastic telescopic sleeve 6 has an elastic contraction force in its free state, an elastic preload is applied between the support body 1 and the slider, causing the slider 2 to always have an elastic restoring force relative to the support body 1 that tends to move in a predetermined direction (towards the patient's occlusal surface or the sensor clamping direction, i.e., downward). In this way, when the patient bites, the slider can automatically adjust its displacement so that the clamping part 100 always fits against the occlusal surface with appropriate elastic force, adapting to the differences in dental arch height among different patients without the need for manual adjustment by the doctor.

[0054] like Figure 1 , Figure 3 As shown, the wire clamp 3 is disposed on the side of the bracket body 1 extending laterally. In this embodiment, the wire clamp 3 is an elastic wire-locking groove 31, which has a narrow opening 32 that opens upwards, and the inner diameter of the groove is slightly smaller than the outer diameter of the signal wire. In use, the signal wire is pressed into the elastic wire-locking groove 31 through the narrow opening 32 and is radially clamped and fixed by the inner wall of the elastic wire-locking groove 31. See also Figure 3In this embodiment, the length extension direction of the elastic wire-locking groove 31 is consistent with the length extension direction of the biting surface 210 on the biting part 200, and the narrow opening 32 of the elastic wire-locking groove 31 is an upward opening, so as to follow the natural wire path after the signal line is led out from the tail of the X-ray sensor inside the opening, so that the cable is smoothly fixed along the biting surface 210.

[0055] like Figure 3 As shown, the biting part 200 is provided with a positioning groove 7, and the inner side of the rubber sleeve 4 is provided with positioning blocks 41 corresponding to the positioning grooves 7. When the rubber sleeve 4 is assembled onto the biting part 200, the positioning blocks 41 are embedded in the positioning grooves 7, thereby fixing the rubber sleeve 4 onto the biting part 200 of the bracket body 1. As a preferred embodiment, the biting part 200 is provided with two positioning grooves 7, one of which is provided on the upper surface of the biting part 200 and the other is provided on the lower surface of the biting part 200; correspondingly, the inner side of the rubber sleeve 4 is provided with two positioning blocks 41, one of which is provided on the upper surface of the inner side of the rubber sleeve 4 and the other is provided on the lower surface of the inner side of the rubber sleeve 4, forming a positioning structure 5 with symmetrical upper and lower sides.

[0056] like Figure 4 As shown, the rubber sleeve 4 is made of medical-grade silicone material, with a hardness lower than that of the support body 1. The rubber sleeve 4 covers the entire occlusal surface 210 and extends to the side edge of the occlusal portion 200. Its edge has a rounded transition to avoid the hard edge scratching the oral soft tissue. The inner side of the rubber sleeve 4 is provided with positioning blocks 41 that correspond one-to-one with the positioning grooves 7. One positioning block 41 is provided on the upper surface and the lower surface of the inner wall of the rubber sleeve 4.

[0057] In use, the intraoral X-ray sensor is clamped in the clamping part 100, and the signal wire of the intraoral X-ray sensor is pressed and fixed into the elastic wire slot 31 of the wire clamp 3. Then, the patient bites the occlusal part 200. Due to the soft elasticity of the rubber sleeve 4, the patient will not feel hard contact pain when biting. Under the elastic restoring force of the elastic telescopic sleeve 6, the upper end of the clamping part 100 is always pressed downward, so that the intraoral X-ray sensor always keeps close to the patient's lingual side. Even if there are individual differences in the patient's dental arch shape, the intraoral X-ray sensor can adaptively fine-tune its position to ensure the coverage of the imaging area, achieving a universal and adjustable clinical effect.

[0058] The universal adjustable bracket assembly for intraoral X-ray sensors of this application can be widely used in dental X-ray imaging diagnostic equipment. As a supporting auxiliary device for digital dental X-ray photography, it has the advantages of simple structure, low cost, good versatility, high patient comfort, and strong clinical adaptability. It is suitable for industrial mass production and clinical promotion and use, thus achieving the purpose of this application.
