Furthermore, features defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly.

[0034] The following is for reference. Figures 1-4 A laser adjustment device 100 according to a first aspect embodiment of the present invention is described.

[0035] The application fields of the laser adjustment device 100 of this utility model are not limited. It can be applied to occasions requiring precise adjustment of the direction and position of the laser emitter 101. For example, in the field of oral medicine, especially in an oral CBCT device 1000, the laser adjustment device 100 can adjust the direction of the laser emitter 101 to ensure that the laser beam can accurately irradiate the area to be scanned, thereby achieving high-precision scanning. As another example, in the field of laser cutting, the laser adjustment device 100 can precisely adjust the emission direction and position of the laser beam to ensure high precision during the cutting process. Yet another example, in the field of laser printing, the laser adjustment device 100 can flexibly adjust the direction and position of the laser beam to adapt to printing requirements of different sizes and shapes. For ease of description, this application describes the laser adjustment device 100 in the field of oral medicine, especially in a CBCT device. Those skilled in the art will readily understand embodiments of the laser adjustment device 100 applied in other fields after reading the following description.

[0036] like Figures 1-2 As shown, the laser adjustment device 100 according to an embodiment of the present invention includes: a mounting base 10, a sleeve 11, an adjustment plate 13, and a locking member 40.

[0037] The sleeve 11 has a cavity 111 extending along a first direction. The cavity 111 is used to mount the laser emitter 101. One end of the sleeve 11 is a laser outlet 112 communicating with the cavity 111, and the other end is disposed on the mounting base 10. A notch 114 is provided on the wall of the sleeve 11, and the notch 114 is provided through the wall along the thickness direction. Here, the first direction is the extension direction of the sleeve 11 in length.

[0038] On the one hand, by setting the sleeve 11, the laser emitter 101 can be stably and accurately installed in the designated position. On the other hand, the sleeve 11 also serves to protect the laser emitter 101, reducing the entry of external impurities and other contaminants into the laser emitter 101, thereby maintaining its good working condition.

[0039] The laser output port 112 serves as a bridge connecting the laser emitter 101 to the external environment, ensuring that the laser emitted by the laser emitter 101 can be transmitted smoothly and accurately to the predetermined target. The structure of the laser output port 112 connecting to the cavity 111 helps to reduce energy loss of the laser during transmission.

[0040] Optionally, the shape and size of the cavity 111 are adapted to the shape and size of the laser emitter 101. This minimizes laser reflection and refraction during transmission, thereby improving laser transmission efficiency. This not only helps extend the lifespan of the laser emitter 101 but also improves the stability and reliability of the entire laser system.

[0041] The notch 114 on the sleeve 11 facilitates the adjustment and locking of the laser emitter 101.

[0042] Specifically, when the laser emitter 101 needs to be adjusted in direction or position, the notch 114 provides an "operation port" through which the operator can access the laser emitter 101. Using this convenient contact point, the operator can rotate, push, or fine-tune the laser emitter 101 to precisely adjust its direction or position.

[0043] Furthermore, the notch 114 also serves a heat dissipation function during the operation of the laser emitter 101. When the laser emitter 101 is in operation, it generates heat. The design of the notch 114 provides a heat dissipation channel. Through the notch 114, the heat generated by the laser emitter 101 can be more effectively dissipated into the surrounding environment, thereby helping to maintain it within a relatively stable operating temperature range.

[0044] In addition, the notch 114 can also reduce the local stiffness of the sleeve 11. By setting the notch 114, the sleeve 11 can more flexibly adapt to shape changes when under stress, thereby reducing potential damage caused by stress concentration. This setting also enables the sleeve 11 to better absorb and disperse stress during the adjustment of the connector 30, ensuring its long-term stability and reliability.

[0045] Combination Figures 1-2 Adjusting plates 13 are provided on the outer circumferential surface of sleeve 11. There are at least two adjusting plates 13 distributed at intervals along the first direction. Each adjusting plate 13 is provided with a connecting part 131. The connecting part 131 on each adjusting plate 13 is correspondingly provided with another connecting part 131 on another adjusting plate 13 along the first direction, and the distance between the two in the first direction is adjustable.

[0046] Therefore, at least two such adjustment plates 13 are mounted on the outer circumferential surface of the sleeve 11. They operate independently but cooperate with each other to jointly complete the adjustment task of the laser emitter 101. Thus, the number of adjustment plates 13 is not fixed; it is at least two, but can be more. This means that when designing the laser adjustment device 100, the number of adjustment plates 13 can be determined according to actual needs and the required adjustment precision.

[0047] Optionally, there are two adjusting plates 13, which are disposed on the outer circumferential surface of the sleeve 11 and are spaced apart along the first direction. This configuration is suitable for simple, linear adjustments to the laser emitter 101.

[0048] Optionally, three adjustment plates 13 are disposed on the outer peripheral surface of the sleeve 11, and the three adjustment plates 13 are arranged at intervals in the first direction. By setting three adjustment plates 13, a more precise adjustment range can be provided. At the same time, due to the greater number of adjustment points, this configuration allows for more complex and multi-dimensional adjustments to the laser emitter 101.

[0049] In this embodiment of the invention, the interval between any two adjusting plates 13 is not limited and can be adjusted according to actual needs. A larger interval provides a wider adjustment range, while a smaller interval improves the accuracy of adjustment.

[0050] Each adjustment plate 13 is equipped with one or more connecting parts 131, which are the connection points between the adjustment plates 13. It is worth noting that the connecting part 131 on each adjustment plate 13 corresponds to another connecting part 131 on another adjustment plate 13 located in the same first direction. This arrangement ensures that the adjustment plates 13 can be linked in an orderly and coordinated manner, thereby achieving precise adjustment of the position and orientation of the laser emitter 101.

[0051] For example, when the distance between the connecting portions 131 on the two adjusting plates 13 decreases in the first direction, this change causes the sleeve 11 to be compressed in that area, thereby causing it to bend. As the sleeve 11 bends, its internal cavity 111 also deforms, thereby changing the laser emission angle.

[0052] Optionally, the two connecting parts 131 are connected by a linkage, chain, or rope. In some cases, the connecting part 30 itself may have an adjustment function, such as fine-tuning through a threaded connection.

[0053] Combination Figure 2 In some optional embodiments, the laser adjustment device 100 further includes a connector 30, which is disposed along a first direction and is connected to two corresponding connecting portions 131 of the two adjustment plates 13.

[0054] The position of at least one of the two connecting portions 131 on the connector 30 is adjustable. This adjustment is made along the first direction, meaning that the effective length of the connector 30 between the two connecting portions 131 can be adjusted by changing the position of the connecting portion 131 on the connector 30.

[0055] Specifically, when the length of the connector 30 between the two connecting parts 131 is adjusted, it is actually fine-tuning the relative position between the two adjusting plates 13. Since these two adjusting plates 13 are connected to the sleeve 11, changes in their relative position directly cause slight changes in the shape or position of the sleeve 11. This change can be a bending phenomenon of the sleeve 11 after being compressed, or an unfolding process of the sleeve 11 when it returns to its extended state after being compressed. Through the deformation of the sleeve 11, the propagation trajectory of the laser emitted by its internal laser emitter can be changed, thereby fine-tuning the laser emission direction.

[0056] In some alternative embodiments, the connector 30 is connected across one or more adjustment plates 13. This arrangement allows for more complex adjustment functions or independent adjustment of a particular adjustment plate 13 without interfering with other adjustment plates 13.

[0057] See Figures 1-2 The locking element 40 is circumferentially connected to the sleeve 11 and connected to both sides of the notch 114 to adjust the circumferential width of the notch 114.

[0058] After the operator successfully adjusts the direction or position of the laser emitter 101 through the notch 114, the locking member 40 is used to ensure that the laser emitter 101 is stably held in the desired position. This locking member 40 applies a tightening force to the sleeve 11 by reducing the circumferential space of the notch 114, thereby firmly locking the laser emitter 101 within the sleeve 11. In this way, even under conditions of vibration or impact in the external environment, the laser emitter 101 can maintain its stability and accuracy, ensuring that the laser beam is consistently pointed at the predetermined target.

[0059] Alternatively, the locking element 40 can be an adjusting bolt. In this way, by using the bolt and nut together, a certain tightening force is generated by rotating the nut, thereby fixing the laser emitter 101.

[0060] Alternatively, the locking element 40 can be a clamp or a holding device. The clamp or holding device is installed around the sleeve 11 and clamped by external force, thereby fixing the laser emitter 101.

[0061] In some alternative embodiments, the mounting base 10, adjusting plate 13, and sleeve 11 are separate components. This means that they can be moved or repositioned relative to each other, providing more space for laser adjustment and allowing the laser beam to be more precisely positioned at the target location. Simultaneously, the separate component design also avoids problems that may arise from rigid connections, such as stress concentration, deformation, or damage. Because the components can move and adjust relatively independently, stress and deformation caused by external factors can be more effectively dispersed and mitigated. Furthermore, the separate component design makes it easier to disassemble and replace each component. Therefore, when a component fails or wears out, it is not necessary to replace the entire system; only the damaged component needs to be replaced, thereby reducing maintenance costs.

[0062] In some alternative embodiments, the mounting base 10, adjusting plate 13, and sleeve 11 can be integral metal parts processed by cutting or casting, reducing installation procedures and lowering costs.

[0063] According to some embodiments of the present invention, the laser adjustment device 100 has at least two notches 114 distributed circumferentially, and at least one locking member 40 is connected to each notch 114.

[0064] In the above technical solution, by setting at least two notches 114 distributed along the circumference, it is convenient for operators to adjust the laser emitter 101 from multiple angles or positions, which can increase the flexibility and convenience of laser adjustment.

[0065] Optionally, the shape and size of the notch 114 can be adjusted according to specific application requirements to ensure that the operator can adjust it directly with their fingers or by using tools, such as rotating or pushing the laser emitter 101.

[0066] In some embodiments, the notch 114 may be an irregular shape; for example, the notch 114 may be wider near the laser emitter 101. This larger notch 114 can provide a certain amount of operating space, allowing an operator to rotate or push the laser emitter 101 using their fingers or tools.

[0067] In some alternative embodiments, such as Figure 2 As shown, the end of the sleeve 11 with the laser outlet 112 is provided with a connecting groove 115, and one end of all the notches 114 extends and connects to the connecting groove 115.

[0068] Specifically, one end of the notch 114 is configured to extend into the connecting groove 115 in the first direction. This extended design makes the notch 114 no longer confined to a local area of ​​the sleeve 11, but forms a through structural feature. When the sleeve 11 is subjected to external forces, these notches 114 and the connecting groove 115 together form a flexible stress relief channel, allowing the sleeve 11 to undergo minor deformation in local areas while maintaining the overall structural integrity.

[0069] By reducing the local stiffness of the sleeve 11, potential damage caused by stress concentration is effectively reduced. When the connector 30 is adjusted, the sleeve 11 can better adapt to shape changes, avoiding stress peaks caused by excessive rigidity. This not only helps improve the durability and stability of the sleeve 11, but also ensures that the laser beam maintains a precise and stable direction during adjustment, providing operators with an intuitive adjustment reference.

[0070] Optionally, the notches 114 are evenly spaced along the circumference of the sleeve 11, and the center of the connecting groove 115 is located at the laser outlet 112.

[0071] The uniformly spaced notches 114 along the circumference of the sleeve 11 mean that they are arranged at equal intervals along the circumference of the sleeve 11.

[0072] On the one hand, the uniformly distributed notches 114 can effectively disperse the stress of the sleeve 11 when subjected to external forces, avoid structural damage caused by stress concentration, thereby improving the durability and stability of the sleeve 11 and ensuring the reliability of the laser adjustment device 100 during long-term use.

[0073] On the other hand, because the notches 114 are evenly distributed, operators can approach the laser emitter 101 from different directions for adjustments. This helps increase operational flexibility and makes the adjustment process more intuitive and convenient.

[0074] In the above technical solution, the center of the connecting groove 115 is also set at the laser outlet 112. This alignment of the connecting groove 115 with the laser outlet 112 makes it easier for the operator to judge and adjust the direction of the laser beam. By observing the relative position of the connecting groove 115 and the laser beam, the operator can intuitively understand the current status of the laser emitter 101 and make necessary fine adjustments.

[0075] According to some embodiments of the present invention, the laser adjustment device 100 has a locking member 40 that is a locking screw. A locking threaded hole is provided on one side of the notch 114, and a locking through hole is provided on the other side of the notch 114. The locking screw passes through the locking through hole and is threaded onto the locking threaded hole.

[0076] In the above technical solution, a locking threaded hole is designed on one side of the notch 114. This locking threaded hole is used to match the threaded portion of the locking screw. When the locking screw is screwed into the threaded hole, it can generate sufficient locking force to shorten the circumferential distance of the notch 114, thereby fixing the laser emitter 101 inside the sleeve 11.

[0077] A locking through-hole is located on the opposite side of the locking threaded hole. The size and shape of this locking through-hole match the shank of the locking screw, allowing it to pass through unobstructed. The design of the locking through-hole ensures that the locking screw can be accurately positioned in the threaded hole and tightened smoothly.

[0078] In some alternative embodiments, the notch 114 extends along a first direction and extends to an adjacent adjusting plate 13. The notch 114 and the adjusting plate 13 are connected by an arc transition.

[0079] First, this rounded transition can effectively disperse stress, thereby reducing the risk of stress concentration at the connection point 131 and enhancing the stability and durability of the structure.

[0080] Secondly, the arc transition can reduce friction and wear between the sleeve 11 and the adjustment plate 13, thereby improving the durability of the laser adjustment device 100.

[0081] According to some embodiments of the present invention, a laser adjustment device 100, combined with... Figures 1-3 The notch 114 includes a wide section 1141 and a narrow section 1142 distributed along a first direction. The narrow section 1142 is located at the end of the sleeve 11 where the laser output port 112 is located, and the wide section 1141 is located between the narrow section 1142 and the adjusting plate 13. The circumferential width of the wide section 1141 is greater than the circumferential width of the narrow section 1142. The locking member 40 is connected to both circumferential sides of the narrow section 1142.

[0082] In the above technical solution, the narrow section 1142 is located at the end of the sleeve 11 where the laser output port 112 is located. Since the narrow section 1142 is relatively compact in size and has a relatively small circumferential width, it helps to provide precise displacement control when adjusting the laser emitter 101.

[0083] The wide-segment opening 1141 is located between the narrow-segment opening 1142 and the adjusting plate 13. Compared with the narrow-segment opening 1142, the wide-segment opening 1141 has a larger circumferential width. This arrangement provides more operating space for the installation, adjustment, and locking processes, thereby improving the efficiency of laser adjustment.

[0084] Locking members 40 are provided on both sides of the narrow opening 1142. The main function of these locking members 40 is to ensure that the laser emitter 101 can be stably fixed after being adjusted to the required position, preventing displacement due to vibration or external interference. Moreover, placing the locking members 40 in the peripheral area of ​​the narrow opening 1142 can effectively avoid potential damage to the laser emitter 101 due to careless operation when adjusting the width of the notch 114, thereby ensuring the safety and reliability of the laser adjustment device 100.

[0085] According to some embodiments of the present invention, the laser adjustment device 100, such as Figures 3-4 As shown, a groove gap 116 is provided between the two adjusting plates 13 corresponding to the connecting piece 30 on the sleeve wall 11.

[0086] The groove clearance 116 can be in the form of an elongated groove extending circumferentially along the sleeve 11. The groove clearance 116 provides additional clearance for the bending of the sleeve 11.

[0087] When the laser adjustment device 100 is bent, the groove gap 116 allows the sleeve 11 to bend moderately in the direction of the groove gap 116 without causing excessive stress or damage to the connector 30 or the entire sleeve 11 structure.

[0088] The structure of the groove gaps 116 also takes into account the relative displacement that may occur between the sleeve 11 and the adjusting plate 13 during bending. By reserving a certain space, these groove gaps 116 ensure that the sleeve 11 can still maintain its original function even in a bent state, thereby ensuring the overall performance and stability of the laser adjustment device 100.

[0089] In some alternative embodiments, the connectors 30 are arranged in pairs, with the two connectors 30 of the same pair connected to the same two adjusting plates 13. The two connectors 30 of the same pair are located on opposite sides of the sleeve 11, and each side of the sleeve 11 has a groove gap 116 on the cylinder wall corresponding to the connector 30. The connector 30 is an adjusting bolt. When one of the two connectors 30 in the pair is used to press down one end of the corresponding adjusting plate 13, the other also locks the two adjacent connecting parts 131 to provide preload.

[0090] In specific adjustments, when the laser line needs to be moved to one side, the corresponding connector 30, i.e., the adjusting bolt, can be adjusted on that side (let's say the first side). By screwing in the adjusting bolt, the adjusting plate 13 on that side is lowered, allowing for approximate position adjustment. Then, by screwing in the adjusting bolt on the other side (let's say the second side), the two connecting parts 131 are locked from the other side. Finally, the first side is slightly tightened to achieve a precise position for the laser line. By adjusting the bolts on both sides, the laser line can be adjusted in two directions according to its movement requirements. Regardless of the direction of adjustment, the two adjusting bolts are always pressed against the corresponding adjusting plate 13 on the mounting base 10. This allows for laser line position adjustment while preventing changes in laser line position due to loosening under the overall pre-tightening force, thus achieving precise and stable laser line position adjustment.

[0091] Combination Figure 1 , Figure 4 A pair of connectors 30, i.e., two connectors 30, are provided on the same adjusting plate 13. These two connectors 30 are located on opposite sides of the adjusting plate 13. When each side is provided with a groove gap 116, the two connectors 30 can deform through the groove gap 116 during tightening, thereby ensuring that the pre-tightening force applied by the connectors 30 on both sides to the sleeve 11 remains balanced.

[0092] This embodiment effectively balances the preload on both sides of the sleeve 11 by providing connecting parts 30 and groove gaps 116 on opposite sides. This not only avoids irreversible deformation and adjustment failure caused by excessive preload time on one side, but also allows for precise control of the laser direction when fine-tuning one side.

[0093] In some alternative embodiments, see Figures 3-4 The two groove gaps 116 corresponding to the two connecting pieces 30 on the sleeve wall of the sleeve 11 are arranged at intervals along the first direction and are respectively set at the connection between the adjusting plate 13 and the sleeve 11, and are distributed at intervals along the radial direction of the sleeve 11.

[0094] Specifically, the two connectors 30 are located on opposite sides of the sleeve 11 wall, and their corresponding groove gaps 116 are spaced apart along the first direction, i.e., the length direction of the sleeve 11. This arrangement ensures that the two groove gaps 116 are staggered in the first direction, preventing them from overlapping at the same or similar positions. The two groove gaps 116 are respectively located at the connection between the adjusting plate 13 and the sleeve 11. This reduces the difficulty of bending the sleeve 11 at the corresponding groove gap 116 by pressing down the adjusting plate 13 with the connectors 30, while also preventing excessive reduction in the strength of the sleeve 11 and ensuring the overall strength of the laser adjustment device.

[0095] Meanwhile, the two groove gaps 116 are radially spaced, which further ensures the strength of the sleeve 11 between the two adjacent adjusting plates 13 and prevents the sleeve 11 from being crushed when the two adjusting plates 13 are locked by the same pair of connecting parts 30.

[0096] The staggered arrangement of the groove gaps 116 can reduce the stress concentration phenomenon of the sleeve 11 when it is under force, thereby making the stress distribution of the sleeve 11 more uniform and improving the reliability of the system.

[0097] According to some embodiments of the laser adjustment device 100 of this utility model, there are two or three adjustment plates 13, with the mounting base 10 serving as one of them, which is the bottom adjustment plate 13. Each pair of adjacent adjustment plates 13 is provided with a corresponding connecting part 131 to connect the connecting member 30. All connecting members 30 are evenly spaced and staggered along the circumference of the sleeve 11.

[0098] By setting two or three adjustment plates 13, a certain adjustment range can be guaranteed, while maintaining the simplicity of the structure and the reliability of the system.

[0099] For example, in some embodiments, there are two adjusting plates 13, each with a corresponding connecting portion 131 for connecting the connecting member 30. There are two connecting members 30, which are staggered circumferentially along the sleeve 11. Due to the staggered arrangement of the two connecting members 30, physical interference or obstruction with the other connecting member 30 can be avoided when adjusting one of them. This ensures the smoothness and accuracy of the adjustment process.

[0100] For example, in some embodiments, there are three adjustment plates 13. Thus, each pair of adjacent adjustment plates 13 has a corresponding connecting portion 131 to connect to the connecting member 30. There are four connecting members 30, which are staggered circumferentially along the sleeve 11. By setting three conditions, more adjustment points can be provided, thereby increasing the adjustment direction and angle of the laser adjustment device 100 to meet more needs. At the same time, the three adjustment plates 13 also disperse the stress of the laser adjustment device 100 under force to a certain extent, making the entire structure more stable. The four connecting members 30 are staggered circumferentially along the sleeve 11, so that the operator can easily access and adjust each connecting member 30 without interfering with other connecting members 30, thereby improving adjustment efficiency.

[0101] In some alternative embodiments, there are three adjusting plates 13, with the mounting base 10 serving as one of them, acting as the bottom adjusting plate 13. Thus, two connecting pieces 30 are provided between the mounting base 10 and the adjacent adjusting plate 13 to connect them. The three adjusting plates 13 can be used to achieve adjustment in two vertical directions, and the mounting base 10, adjusting plates 13, and sleeve 11 can form a symmetrical structure as a whole.

[0102] In the above embodiments, the adjustment plate 13 and the mounting base 10 are no longer regarded as two independent components. Instead, one of the adjustment plates 13 is designed as part of the mounting base 10. This not only integrates and reduces the number of components and simplifies the assembly process, but also ensures the system's adjustment capability.

[0103] According to some embodiments of the laser adjustment device 100 of the present invention, the cavity 111 of the sleeve 11 has a stop surface (not shown in the figure) at one end of the laser outlet 112. The other end of the sleeve 11 is provided with a mounting port, and a mounting port is also provided at a corresponding position on the mounting base.

[0104] The stop surface can be a plane or a surface with a certain shape. This stop surface is used to contact or come into close contact with the laser emitter 101, thereby preventing the laser beam from falling off during the output process and providing certain support and positioning for the laser emitter 101.

[0105] The sleeve 11 is connected to the mounting base 10 through the mounting port.

[0106] like Figures 5-6 As shown, the dental CBCT device 1000 according to a second aspect embodiment of the present invention includes: a support frame 200, a C-arm 300, and a laser adjustment device 100. A C-arm fixing part 201 is provided at the top of the support frame 200. The C-arm 300 is rotatably connected to the bottom of the C-arm fixing part 201. The laser adjustment device 100 is provided at one end of the C-arm 300, and the laser adjustment device 100 is the laser adjustment device 100 according to the first aspect embodiment of the present invention.

[0107] Understandably, the support frame 200 serves as the foundation of the dental CBCT equipment 1000, and various components, such as the C-arm fixing part 201, are connected to the support frame 200, thereby improving the operational stability of the dental CBCT equipment 1000.

[0108] The C-arm 300 is one of the main components of the oral CBCT device 1000. It surrounds the patient's oral cavity area and is used to emit X-rays and receive images formed after passing through the patient's oral cavity.

[0109] In actual operation, the C-arm 300 can rotate around the bottom of the C-arm fixing part 201 to drive the laser adjustment device 100, CT detection component, etc. to rotate 360 ​​degrees. During the rotation, the CT detection component can receive the radiation emitted by the radiation source, thereby realizing the imaging.

[0110] The laser adjustment device 100 is located at one end of the C-arm 300 and is used to locate and calibrate the patient's oral cavity area before scanning.

[0111] With the laser adjustment device 100, doctors can directly see the projection position of the laser beam in the patient's mouth, thus ensuring the accuracy of the scan.

[0112] By setting the laser adjustment device 100 of the first aspect embodiment of this utility model, the laser in the dental CBCT device 1000 can be precisely adjusted, while reducing the manufacturing cost of the dental CBCT device 1000.
