Description

Technical Field

[0001] This application relates to medical devices, specifically to a rotating connection structure for an X-ray imaging device. Background Technology

[0002] An X-ray imaging device is a device that uses X-rays to pass through the human body, be collected by a flat panel detector, and processed by a computer system to reproduce X-ray images. In this device, the X-ray head is used to emit X-rays, and the film cassette is used to mount the flat panel detector. Typically, the X-ray head and film cassette are mounted on their respective columns. To accommodate different user heights and allow for flexible adjustment of the height of the X-ray head and film cassette, they are usually designed to be raised and lowered on their respective columns.

[0003] During the examination, the subject stands between the X-ray head and the film cassette. By adjusting the height of the film cassette and the X-ray head, different parts of the subject can be imaged with X-rays. However, since the X-ray head generally needs to rotate vertically, the column mounting the head is usually rotatably mounted on the base. This rotation function requires a dedicated rotating connection structure between the column and the base, but existing rotating connection structures are not optimized, resulting in excessive vertical space occupation. This restricts the movement of the X-ray head to a lower position on the column, making it difficult to capture images near the subject's ankles. Often, the subject must stand on a mat or other object with height to properly image their ankles, which causes considerable inconvenience. Summary of the Invention

[0004] This application provides an X-ray imaging device that enables the camera head to move downwards on the column to a lower position, allowing the camera head to capture images at a lower angle.

[0074] To achieve the above objectives, one embodiment of this application provides an emitting device for an X-ray imaging apparatus, comprising:

[0075] A support device having a base and a rotating assembly;

[0076] A head mounting assembly for mounting a head, the head mounting assembly having a connecting base plate;

[0077] And the head unit, which is used to emit X-rays;

[0078] The base, the rotating component, and the connecting substrate are rotated together using a rotating connection structure as described above.

[0079] In one embodiment, the support device includes a ceiling track assembly for mounting above the testing site, and the head mounting assembly is a head lifting assembly with lifting function, wherein the head is mounted on the head lifting assembly.

[0080] For the above purposes, one embodiment of this application provides an X-ray imaging system, including a receiving device and a transmitting device as described in any of the above claims;

[0082] Alternatively, it may include the receiving device as described in any of the preceding claims and the transmitting device as described in any of the preceding claims.

[0083] According to the above embodiment, the emitting device of the X-ray imaging equipment has a support device with a base and a rotating assembly, and the column has a connecting base plate. The connecting base plate and the base are stacked on the same side of the rotating assembly. One of the base and the connecting base plate has a clearance area on the side facing the rotating assembly, and the other is at least partially accommodated in the clearance area. Thus, in the axial direction of the rotating assembly, while ensuring that the base and the connecting base plate are respectively connected to the rotating assembly, the axial thickness of the entire rotating connection structure of the connecting base plate, the rotating assembly, and the base can be reduced, thereby reducing the space occupied by the rotating connection structure in the vertical direction and leaving more space for the downward movement of the machine head.

One of the base and the connecting base plate has a clearance area on the side facing the rotating assembly, and the other is at least partially accommodated within the clearance area. This reduces the axial thickness of the entire rotating connection structure (connecting base plate, rotating assembly, and base) in the axial direction of the rotating assembly. When the emitting device employs the rotating connection structure, more space can be provided for other structures, such as more space for the movement of the imaging head.

[0088] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings. Similar elements in different embodiments are referred to by associated similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of this application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to this application are not shown or described in the specification. This is to avoid obscuring the core parts of this application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0089] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0090] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0091] This application provides an X-ray imaging device in some embodiments; please refer to [reference needed]. Figure 1 The X-ray imaging equipment typically includes a transmitting device 1 and a receiving device 2. The transmitting device 1 includes a head unit 100, which has an X-ray emitter for emitting X-rays and other related components. The receiving device 2 includes a film cassette 200. The film cassette 200 has a receiving cavity for accommodating a flat panel detector (i.e., an X-ray detector). X-rays emitted by the head unit 100 pass through the human body and are collected by the flat panel detector, then processed by a computer system to ultimately form an X-ray imaging image. The head unit 100 and the film cassette 200 are respectively mounted on their respective columns 300. For ease of distinction, the column 300 used to mount the head unit 100 will be referred to as the first column 310, and the column 300 used to mount the film cassette 200 will be referred to as the second column 320.

[0092] The head unit 100 and the film cassette 200 can be respectively mounted on the corresponding support device 400. Please refer to [reference needed]. Figure 1 and 2The support device 400 is used to provide support force. The support device 400 can be fixed or can have translation or other forms of horizontal movement to adjust the horizontal position of the machine head 100 and the film cassette 200.

[0093] To accommodate different patient heights and allow for flexible adjustment of the height of the X-ray machine head 100 and film cassette 200, both the machine head 100 and film cassette 200 can be raised and lowered on the first column 310 and the second column 320, respectively. Simultaneously, to enhance the flexibility of the machine head 100 and / or film cassette 200, in some scenarios, it is desirable for the machine head 100 and / or film cassette 200 to rotate vertically. This rotation function is achieved through a rotating connection structure between the column 300 (which can be the first column 310 and / or the second column 320) and the support device 400. However, this rotating connection structure typically occupies vertical space, affecting the lowest vertical position of the machine head 100 and / or film cassette 200; for example, in typical X-ray imaging equipment, it is difficult to capture images near the patient's ankles.

[0094] Please refer to Figure 3-6 In some embodiments of this application, a rotating connection structure for an X-ray imaging device is provided.

[0095] The rotating connection structure includes a base 430, a connecting base plate 330, and a rotating assembly 450. The rotating assembly 450 is an intermediate connecting component capable of rotation, and can be, for example, but not limited to, bearings, especially crossed roller bearings, angular contact ball bearings, point contact ball bearings, or turntable bearings. These types of bearings occupy less space in the axial direction, which is more conducive to reducing the thickness of the entire rotating connection structure in the axial direction (i.e., the direction of the rotation axis). Of course, the rotating assembly 450 can also have other structures, such as a shaft and a rotating hole fitting together to achieve relative rotation.

[0096] The rotating assembly 450 includes an inner ring 451 and an outer ring 452 disposed outside the inner ring 451, the outer ring 452 being rotatable relative to the inner ring 451. When the rotating assembly 450 is a bearing, a rolling element 453 can be provided between the inner ring 451 and the outer ring 452 to achieve rotation of the inner ring 451 and the outer ring 452. The inner ring 451 and the outer ring 452 can also be in direct contact, for example, in a shaft-hole fit, where the rotating shaft is in direct contact with the wall of the rotating hole.

[0097] The connecting base plate 330 is used to connect the rotating object, and the base 430 is used to connect the support device 400, thereby realizing the relative rotation between the rotating object and the support device 400. The rotating object can be a column 300 (either a first column 310 or a second column 320) on which the head 100 and / or the cartridge 200 are mounted.

[0098] Please refer to Figure 3-6 The connecting base plate 330 and the base 430 are partially or entirely located on the same side of the rotating assembly 450, which can be either the upper side or the lower side of the rotating assembly 450. One of the connecting base plate 330 and the base 430 is mounted on the inner ring member 451, and the other is mounted on the outer ring member 452, allowing the connecting base plate 330 to rotate relative to the base 430.

[0099] like Figure 3 and 4 As shown, in one embodiment, in order to reduce the axial dimension of the entire rotating connection structure, one of the base 430 and the connecting substrate 330 has a clearance region 431 on the side facing the rotating assembly 450, and the other part or all of the connecting substrate 330 and the base 430 is accommodated in the clearance region 431. In these embodiments, because the base 430 and the connecting substrate 330 are at least partially interlocked, compared to the base 430 and the connecting substrate 330 directly overlapping, this interlocking structure can both meet the strength requirements for support and connection of the connecting substrate 330 and the base 430, and reduce the overall space occupied by the base 430 and the connecting substrate 330 in the axial direction, thereby reducing the thickness of the entire rotating connection structure in the axial direction (i.e., the direction of the rotation axis). Thus, when the column 300 is connected to the support device 400 through the rotating connection structure, the head 100 and / or the cassette 200 can move to a lower position in the vertical direction to achieve detection at a lower position.

[0100] like Figure 5 and 6 In other embodiments, to reduce the axial dimension of the entire rotating connection structure, one of the connecting base plate 330 and the base 430 is circumferentially arranged around the other. The inner component of the connecting base plate 330 and the base 430 is connected to the inner ring member 451, and the outer component is connected to the outer ring member 452, allowing the connecting base plate 330 to rotate relative to the base 430. For example, in... Figure 5 In the illustrated embodiment, the connecting substrate 330 is located on the inner side, and the base 430 is disposed around the connecting substrate 330. Figure 6 In the illustrated embodiment, the base 430 is located on the inner side, and the connecting substrate 330 is disposed around the base 430.

[0101] exist Figure 5 and 6In the illustrated embodiment, the orthographic projections of the connecting substrate 330 and the base 430 on the horizontal plane can be further made non-overlapping. This horizontal plane refers to a plane perpendicular to the axial direction of the rotating assembly 450. That is, the connecting substrate 330 and the base 430 do not overlap axially. The thickness of the connecting substrate 330 and the base 430 primarily meets the requirements for support and connection strength, allowing for a thinner overall thickness. This enables the head 100 and / or the cassette 200 to move to a lower position vertically when the column 300 is connected to the support device 400 via the rotating connection structure, thus facilitating detection at a lower location.

[0102] Further, please refer to Figure 3 In one embodiment, the connecting base plate 330 and the base 430 are disposed on the upper side of the rotating assembly 450, wherein the base 430 is fixed to the outer ring member 452, and the connecting base plate 330 is fixed to the inner ring member 451. In this structure, the base 430 is a support structure, and the rotating assembly 450 and the connecting base plate 330 are mounted on the base 430, thereby supporting the column 300 and the machine head 100 and / or the disc cassette 200 thereon. In this embodiment, because the rotating assembly 450 is disposed below the base 430 and the connecting base plate 330, the rotating assembly 450 can also be hidden in the support device 400, which not only protects the rotating assembly 450 but also simplifies the structure of the column 300, eliminating the need for complex design of the column 300 structure to accommodate the rotating assembly 450.

[0103] Please continue to refer to this. Figure 3 In this embodiment, the bottom surface of the connecting substrate 330 is provided with a clearance area 331, and a portion of the base 430 is accommodated within the clearance area 331. With this structure, the connecting substrate 330 can cover at least a portion of the base 430 from above, thereby covering the assembly points of the base 430 and the outer ring member 452, as well as the assembly points of the connecting substrate 330 and the inner ring member 451. This places the assembly points internally and prevents them from being exposed, improving the aesthetic simplicity and preventing foreign objects from entering the assembly points from the outside, thus ensuring the reliability of the rotational connection. Furthermore, in some embodiments, the connecting substrate 330 can form a larger support surface, which is beneficial for the base 430 to directly or indirectly support the connecting substrate 330.

[0104] The base 430 may be entirely located within the clearance area 331, or a portion of the base 430 may be placed within the clearance area 331. The portion of the base 430 extending beyond the connecting base plate 330 may serve other purposes, such as forming a side plate, thereby allowing the base 430 to be mounted on the ground rail of the support device 400.

[0105] In some embodiments, the base 430 can also serve as an outer cover to cover the internal structure of the support device 400. For example, when the support device 400 includes a trolley 410, the base 430 can also serve as a top cover for the trolley 410, which can cover other structures of the trolley 410.

[0106] For details, please continue to refer to Figure 3 In one embodiment, the connecting base plate 330 has a protruding connecting portion 332 in the middle, and the connecting portion 332 is fixedly connected to the inner ring member 451. The outer peripheral area of ​​the connecting portion 332 forms a stepped structure, and the stepped structure forms a clearance area 331. The protruding connecting portion 332 serves as a reinforcing rib, thereby enhancing the strength of the middle part of the connecting base plate 330, ensuring the reliability of the rotational connection, and also improving the support strength for other structures of the column 300.

[0107] The stepped structure can form a convex shaft structure. In one embodiment, the base 430 has a mating hole, the connecting portion 332 passes through the mating hole, and the base 430 is sleeved on the connecting portion 332. Of course, the base 430 can also be in other shapes to mate with the connecting substrate 330.

[0108] Please refer to Figure 4 In another embodiment, the connecting base plate 330 and the base 430 are disposed below the rotating assembly 450, the base 430 is fixed to the inner ring member 451, and the connecting base plate 330 is fixed to the outer ring member 452. In this case, the rotating assembly 450 is located above the base 430 and the connecting base plate 330, which facilitates the installation of the rotating assembly 450.

[0109] Please continue to refer to this. Figure 4 In this embodiment, the clearance area 431 is located on the top surface of the base 430, and a portion of the connecting substrate 330 is accommodated within the clearance area 431. Of course, the clearance area 431 can also be configured in other shapes. In this embodiment, the base 430 can be configured as a structure with a protruding connecting portion 432, which increases the strength of the middle part of the base 430 to better support the rotating assembly 450, the connecting substrate 330, and the column 300, etc. The connecting substrate 330 has a mating hole, and the connecting portion 432 passes through the mating hole from bottom to top.

[0110] exist Figure 4 Therefore, in this embodiment, the side of the base 430 may also extend beyond the connecting base plate 330 to form a side plate or similar shape, which cooperates with the ground rail 420 or the like. The base 430 may also be used as a top cover for the trolley 410 or other components of the support device 400.

[0111] Please refer to Figure 5In one embodiment, the connecting base plate 330 and the base 430 are disposed on the upper side of the rotating assembly 450, with the base 430 arranged circumferentially around the connecting base plate 330. The base 430 is fixed to the outer ring member 452, and the connecting base plate 330 is fixed to the inner ring member 451. This structure can also hide the rotating assembly 450 under the connecting base plate 330 and the base 430. The thickness of the connecting base plate 330 and the base 430 can be selected according to the requirements of connection and support strength. For example, in one embodiment, to improve the support strength of the connecting base plate 330 for the column 300 and its upper machine head 100 and / or cassette 200, the thickness of the connecting base plate 330 can be greater than that of the base 430. Of course, in other embodiments, the thickness of the connecting base plate 330 and the base 430 can be the same, or the base 430 can be thicker.

[0112] Please refer to Figure 6 In one embodiment, the connecting base plate 330 and the base 430 are disposed on the lower side of the rotating assembly 450, with the connecting base plate 330 arranged circumferentially around the base 430. The connecting base plate 330 is fixed to the outer ring member 452, and the base 430 is fixed to the inner ring member 451. Similarly, the thickness of the connecting base plate 330 and the base 430 can be selected according to the requirements of connection and support strength, and the thickness of the connecting base plate 330 can be greater than, less than, or equal to that of the base 430.

[0113] Furthermore, in order to minimize the axial thickness of the entire rotating connection structure, in one embodiment, please refer to... Figure 3-6 In some embodiments, the inner ring 451 has a through first threaded hole, which is a countersunk hole capable of receiving the head of the first threaded part 454 (such as a screw or bolt, the same below). The first threaded part 454 is recessed into the first threaded hole, and the inner ring 451 is fixed to the corresponding connecting base plate 330 or base 430.

[0114] For example, please refer to Figure 3-6 In some embodiments, the outer ring 452 has a through second threaded hole, which is a countersunk hole capable of receiving the head of the second threaded member 455. The second threaded member 455 is recessed into the second threaded hole, and the outer ring 452 is fixed to the corresponding base 430 or connecting substrate 330.

[0115] This countersunk hole design avoids the threaded parts (first threaded part 454 and second threaded part 455) protruding from the outer surface of the rotating assembly 450 in the axial direction, which would occupy the axial space and thus affect the lowest position of the machine head 100 and / or the disc cassette 200 moving downward.

[0116] Please refer to Figure 3-6 In some embodiments, the outer sides of the first threaded member 454 and the second threaded member 455 are flush.

[0117] Please continue to refer to this. Figure 3-6 In some embodiments, on the axial direction of the rotating assembly 450, the side where the connecting base plate 330 and the base 430 are located is the first side, and the side opposite to the first side is the second side. The first threaded member 454 and the second threaded member 455 are respectively inserted into the first threaded hole and the second threaded hole from the second side.

[0118] Because the column 300 is located above the rotating assembly 450, and the column 300 is typically a vertical strip structure, if the threaded parts are installed from above the rotating assembly 450, the bottom of the column 300 needs to be designed separately to allow for easy disassembly of the connecting base plate 330 from other structures of the column 300, in order to install the first threaded part 454 and the second threaded part 455. This would make the structure of the column 300 more complex and the assembly more difficult. Figure 3 and 5 In the embodiment shown, the first threaded component 454 and the second threaded component 455 can be inserted from the underside of the rotating assembly 450 without changing the structure of the bottom of the column 300, which simplifies the assembly process and reduces manufacturing and assembly costs.

[0119] Of course, in some embodiments, the first threaded member 454 and the second threaded member 455 may be inserted into the first threaded hole and the second threaded hole from the first side, respectively.

[0120] To improve locking stability, in some embodiments, there are at least four first threaded members 454 and at least four second threaded members 455. The first threaded members 454 are arranged around the axis of the inner ring member 451, and the second threaded members 455 are arranged around the axis of the outer ring member 452. For example, in some embodiments, these first threaded members 454 and second threaded members 455 are all arranged on the rotating assembly 450 at equal intervals.

[0121] In some other embodiments, the threaded component may also be locked onto the rotating assembly 450 from one side of the connecting base plate 330 and the base 430. For example, the connecting base plate 330 has a through-hole third threaded hole, which is a countersunk hole capable of receiving the head of the third threaded component. The third threaded component is recessed into the third threaded hole, and the connecting base plate 330 is fixed to the corresponding outer ring 452 or inner ring 451.

[0122] For example, in some embodiments, the base 430 has a through-hole fourth threaded hole, which is a countersunk hole that can receive the head of the fourth threaded part. The fourth threaded part is recessed into the fourth threaded hole and fixes the base 430 to the corresponding inner ring 451 or outer ring 452.

[0123] Similarly, this countersunk hole design avoids the threaded parts (the third and fourth threaded parts) protruding from the outer surface of the connecting base plate 330 and the base 430, which would occupy the axial space and thus affect the lowest position of the machine head 100 and / or the disc cassette 200 moving downward.

[0124] In one embodiment, the outer sides of the third and fourth threaded parts are flush.

[0125] Furthermore, in some rotating components 450, such as some bearings, the inner ring 451 and the outer ring 452 are typically not at the same axial height, resulting in an increase in the overall axial dimension of the rotating component 450. For this, please refer to... Figure 3-6 In one embodiment, the outer ring 452 and the inner ring 451 are flush at both ends along the axial direction of the rotating assembly 450, thereby minimizing the overall thickness of the rotating assembly 450 while ensuring the thickness requirements of the outer ring 452 and the inner ring 451.

[0126] The rotating connection structures shown in the above embodiments can be applied to various X-ray imaging devices that require rotation and lifting.

[0127] For example, please refer to Figure 1 In one embodiment, the emitting device of the X-ray imaging equipment includes a support device 400, a column 300, and a head unit 100. The support device 400 has a base 430 and a rotating assembly 450. The bottom of the column 300 has a connecting base plate 330. The base 430, the rotating assembly 450, and the connecting base plate 330 can form a rotating connection structure as shown in any of the above embodiments, reducing the vertical space occupied by the rotating connection structure, thereby allowing the head unit 100 to move downward to a lower position.

[0128] Alternatively, please refer to Figure 1 In one embodiment, the receiving device of the X-ray imaging equipment includes a support device 400, a column 300, and a film cassette 200. The support device 400 has a base 430 and a rotating assembly 450, and the bottom of the column 300 has a connecting base plate 330. The base 430, the rotating assembly 450, and the connecting base plate 330 can form a rotating connection structure as shown in any of the above embodiments, reducing the vertical space occupied by the rotating connection structure, thereby allowing the film cassette 200 to move downward to a lower position.

[0129] exist Figure 1In the illustrated embodiment, the support device 400 includes a trolley 410 and a ground rail 420. The trolley 410 has a base 430, a rotating assembly 450, and at least two opposing moving assemblies. The trolley 410 spans the ground rail 420, and the moving assemblies are connected to the base 430 and respectively disposed on both sides of the base 430, so that the trolley 410 can move along the ground rail 420 via the moving assemblies. This structure, in which the trolley 410 and the ground rail 420 are arranged to move relative to each other on both sides of the ground rail 420, can further reduce the height of the support device 400, which is beneficial for moving the machine head 100 and / or the film cassette 200 downward to a lower position. The moving assemblies can use structures such as roller assemblies, bearing assemblies, and sliders to achieve sliding or rolling.

[0130] In other embodiments, the support device 400 may also be replaced by a ceiling track (a track installed on the ceiling, etc.), which is connected to the column 300 by the above-described rotating connection structure. The column 300 can be used to install the head 100 and / or the cartridge 200.

[0131] The above examples illustrate the present invention only to aid in understanding it and are not intended to limit the scope of the invention. Those skilled in the art can make various simple deductions, modifications, or substitutions based on the principles of this invention.
