Description

Technical Field

[0001] This utility model relates to the field of medical equipment, and more particularly to a support mechanism for a medical X-ray imaging device, and a medical X-ray imaging device including the support mechanism. Background Technology

[0002] In X-ray imaging, the perpendicularity of the X-ray tube beam axis to the incident surface of the image receiver directly affects the image quality. Currently, the C-arm support arm of C-arm X-ray machines is rigidly connected to the X-ray tube, making it difficult to calibrate the angle of the X-ray tube and thus making it difficult to meet the design requirements for the perpendicularity of the X-ray tube beam axis to the incident surface of the image receiver. Utility Model Content

[0003] The purpose of this invention is to provide a support mechanism for a medical X-ray imaging device, which facilitates the adjustment of the tube angle.

[0004] Another objective of this invention is to provide a medical X-ray imaging device that allows for easy adjustment of the tube angle.

[0005] This invention provides a support mechanism for a medical X-ray imaging device, comprising a bracket and a mounting base. The mounting base is used to mount an X-ray tube or is part of an X-ray tube. The beam axis of the X-ray tube is parallel to the height direction of the mounting base. The end of the mounting base along its length is movably connected to the bracket, allowing the mounting base to rotate with three degrees of freedom relative to the bracket.

[0006] The support mechanism of this medical X-ray imaging equipment allows for easy adjustment of the tube angle.

[0007] In another illustrative embodiment of the support mechanism for a medical X-ray imaging device, a connecting portion is provided at the end of the mounting base along its length. The connecting portion has a mounting hole extending through the width of the mounting base. The bracket includes a connecting rod. The connecting rod passes through the mounting hole and is connected to the wall of the mounting hole via a spherical joint structure. This structure has good stability.

[0008] In another illustrative embodiment of the support mechanism for a medical X-ray imaging device, the support mechanism further includes a radial spherical bearing. The outer ring of the radial spherical bearing is fixed within a mounting hole. A connecting rod passes coaxially through the inner ring of the radial spherical bearing. The radial spherical bearing has a large load-bearing capacity, which helps to improve the stability of the overall structure.

[0009] In another illustrative embodiment of the support mechanism for a medical X-ray imaging device, the support mechanism further includes positioning bolts. The positioning bolts connect the bracket and the mounting base to fix their relative rotational position. At least one positioning bolt passes through the connecting rod and is threaded to the mounting base. The positioning bolt passing through the connecting rod can press the connecting rod towards the mounting base through its bolt head or a mating nut. This structure is simple and facilitates positioning operations.

[0010] In another illustrative embodiment of the support mechanism for a medical X-ray imaging device, several positioning bolts pass through the connecting rod and are threadedly connected to the mounting base. These positioning bolts are distributed on both sides of the connection portion along the length of the connecting rod. This facilitates improved fixation stability.

[0011] In another illustrative embodiment of the support mechanism for a medical X-ray imaging device, the bracket further includes a positioning rod. The positioning rod is parallel to the connecting rod. The support mechanism also includes positioning bolts. The positioning bolts connect the bracket and the mounting base to fix their relative rotational positions. At least one positioning bolt passes through the positioning rod and is threaded to the mounting base. The positioning bolt passing through the positioning rod can press the positioning rod toward the mounting base through its bolt head or a mating nut. This structure is simple, facilitates positioning operations, and has good fixation stability.

[0012] In another illustrative embodiment of the support mechanism for a medical X-ray imaging device, several positioning bolts pass through the positioning rod and are threadedly connected to the mounting base. These positioning bolts are distributed on both sides of the connection part along the length of the positioning rod. This facilitates improved fixation stability.

[0013] In another illustrative embodiment of the support mechanism for a medical X-ray imaging device, the mounting base has a mounting end face parallel to its width direction at its length end. A connecting portion protrudes from the mounting end face. A positioning bolt is inserted into the mounting base from the mounting end face for threaded connection with the mounting base. This allows for a more compact overall structure.

[0014] In another illustrative embodiment of the support mechanism for medical X-ray imaging equipment, the bracket further includes a support body. The support body covers the mounting end face and has a cavity facing the mounting end face. A connecting rod and a positioning rod are disposed in the cavity and connected to the support body at both ends. A connecting portion extends into the cavity and connects to the connecting rod. This enhances safety and protection, and also facilitates a simple and streamlined appearance.

[0015] In another illustrative embodiment of the support mechanism for a medical X-ray imaging device, the support body has an operating port that connects to the cavity. This allows for convenient adjustment and operation.

[0016] In another illustrative embodiment of the support mechanism of the medical X-ray imaging equipment, the support mechanism is further provided with a cover for covering the operating port and a housing detachably connected to the mounting base. The cover is connected to the housing. The cover prevents foreign objects from entering the cavity.

[0017] This invention also provides a medical X-ray imaging device, which includes the support mechanism described above. This medical X-ray imaging device allows for easy adjustment of the X-ray tube angle.

[0018] In another illustrative embodiment of the medical X-ray imaging device, the medical X-ray imaging device is a C-arm X-ray machine. The support is the C-shaped support arm of the C-arm X-ray machine. Attached Figure Description

[0043] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, specific embodiments of the present utility model are now described with reference to the accompanying drawings. In the drawings, the same reference numerals indicate components with the same or similar structures but the same function.

[0044] In this document, “illustrative” means “serving as an example, illustration or description”, and any illustration or implementation described herein as “illustrative” should not be construed as a more preferred or advantageous technical solution.

[0045] To keep the drawings simple, each drawing only schematically shows the parts related to this utility model, and they do not represent the actual structure of the product.

[0046] Figure 1 This is a schematic structural diagram illustrating one embodiment of a support mechanism for a medical X-ray imaging device. The medical X-ray imaging device is, for example, a C-arm X-ray machine, but is not limited thereto.

[0047] like Figure 1 As shown, the support mechanism of the medical X-ray imaging equipment includes a bracket 10 and a mounting base 20. The bracket 10 is, for example, the C-shaped support arm of a C-arm X-ray machine, but is not limited thereto. The mounting base 20 is, for example, used to mount the X-ray tube. The mounting base 20 is, for example, a box-shaped housing with an internal cavity in which the X-ray tube is, for example, fixedly mounted, but is not limited thereto. In other illustrative embodiments, the mounting base 20 may also be part of the X-ray tube; specifically, the mounting base 20 may be, for example, a support structure for the X-ray tube, but is not limited thereto. For ease of explanation, this illustrative embodiment is illustrated in conjunction with the height direction H, length direction L, and width direction W of the mounting base 20, which are, for example, mutually perpendicular. The beam axis of the X-ray tube is parallel to the height direction H of the mounting base 20.

[0048] The end of the mounting base 20 along its length L (i.e. Figure 1The left end of the mounting base 20 is movably connected to the bracket 10, allowing the mounting base 20 to rotate with three degrees of freedom relative to the bracket 10. That is, the mounting base 20 can rotate relative to the bracket 10 about three independent orthogonal axes in three-dimensional space, and these three rotational movements are unrestricted by each other. This facilitates the adjustment of the X-ray tube angle.

[0049] Specifically, in this illustrative embodiment, a connecting portion 21 is provided at the end of the mounting base 20 along its length direction L. The connecting portion 21 has a mounting hole 211 extending through the width direction W of the mounting base 20. The bracket 10 includes a support body 13 and a connecting rod 11. Both ends of the connecting rod 11 are connected to the support body 13. The connecting rod 11 passes through the mounting hole 211 and is connected to the hole wall of the mounting hole 211 through a spherical joint structure. This structure has good stability. Specifically, in this illustrative embodiment, the support mechanism also includes a radial spherical bearing 30. The connecting rod 11 is connected to the hole wall of the mounting hole 211 through the radial spherical bearing 30. The outer ring of the radial spherical bearing 30 is fixed inside the mounting hole 211, and the connecting rod 11 is coaxially passed through the inner ring of the radial spherical bearing 30. The radial spherical bearing 30 has a large load-bearing capacity, which is beneficial to improving the stability of the overall structure, but is not limited thereto. In other illustrative embodiments, a spherical pair structure can also be formed by combining an outer spherical surface formed on the surface of the connecting rod 11 and an inner spherical surface formed on the wall of the mounting hole 211.

[0050] Figure 2 for Figure 1 The diagram shows a cross-sectional view of the support mechanism for the medical X-ray imaging equipment, where the cut surface is perpendicular to the width direction W of the mounting base 20. Figure 1 and Figure 2 As shown in the illustrative embodiment, the support mechanism further includes two positioning bolts 40 that pass through the connecting rod 11 and are threadedly connected to the mounting base 20. These two positioning bolts 40 can press the connecting rod 11 towards the mounting base 20 through their bolt heads to fix the relative rotational position of the bracket 10 and the mounting base 20. In other illustrative embodiments, the positioning bolts 40 passing through the connecting rod 11 can also press the connecting rod 11 towards the mounting base 20 through mating nuts. In other illustrative embodiments, the number of positioning bolts 40 passing through the connecting rod 11 can be adjusted as needed, for example, to one or more.

[0051] When it is necessary to adjust the relative rotational position of the bracket 10 and the mounting base 20, first loosen the positioning bolt 40 to allow the mounting base 20 to rotate relative to the bracket 10. After adjusting to the appropriate angle, tighten the positioning bolt 40 to fix the relative rotational position of the bracket 10 and the mounting base 20.

[0052] It is understood that the size of the through hole on the connecting rod 11 for the positioning bolt 40 is set to allow the loosened positioning bolt 40 to not interfere with the connecting rod 11 when the mounting base 20 rotates relative to the bracket 10 within a set angle adjustment range, which is typically small. In the illustrative embodiment, the two ends of the connecting rod 11 are rotatably connected to the support body 13, for example, about its own axis, to facilitate reducing interference, but this is not a limitation; in other illustrative embodiments, the two ends of the connecting rod 11 may also be fixedly connected to the support body 13.

[0053] In this illustrative embodiment, two positioning bolts 40, which pass through the connecting rod 11, are respectively located on both sides of the connecting portion 21 along the length of the connecting rod 11. This helps to improve the stability of the fixation.

[0054] like Figure 1 and Figure 2 As shown, in the illustrative embodiment, the bracket 10 further includes a positioning rod 12. The positioning rod 12 is parallel to the connecting rod 11 and its two ends are connected to the support body 13. The support mechanism also includes two positioning bolts 40 that pass through the positioning rod 12 and are threadedly connected to the mounting base 20. These two positioning bolts 40 can press the positioning rod 12 toward the mounting base 20 through their bolt heads to fix the relative rotational position of the bracket 10 and the mounting base 20. In other illustrative embodiments, the positioning bolts 40 passing through the positioning rod 12 can also press the positioning rod 12 toward the mounting base 20 through the nuts that mate with them. In other illustrative embodiments, the number of positioning bolts 40 passing through the positioning rod 12 can be adjusted as needed, for example, to one or more.

[0055] When it is necessary to adjust the relative rotational position of the bracket 10 and the mounting base 20, first loosen the positioning bolt 40 to allow the mounting base 20 to rotate relative to the bracket 10. After adjusting to the appropriate angle, tighten the positioning bolt 40 to fix the relative rotational position of the bracket 10 and the mounting base 20.

[0056] It is understood that the size of the through hole on the positioning rod 12 for passing through the positioning bolt 40 is set to allow the loosened positioning bolt 40 to not interfere with the positioning rod 12 when the mounting base 20 rotates relative to the bracket 10 within a set angular adjustment range. In the illustrative embodiment, the two ends of the positioning rod 12 are rotatably connected to the support body 13, for example, about its own axis, to facilitate reducing interference, but it is not limited thereto; in other illustrative embodiments, the two ends of the positioning rod 12 may also be fixedly connected to the support body 13.

[0057] In this illustrative embodiment, two positioning bolts 40, which pass through the positioning rod 12, are respectively located on both sides of the connecting portion 21 along the length direction of the positioning rod 12. This helps to improve the stability of the fixation.

[0058] In other illustrative embodiments, the relative rotational position of the bracket 10 and the mounting base 20 can be fixed simply by using the positioning bolt 40 passing through the positioning rod 12, without the need to use the positioning bolt 40 passing through the connecting rod 11.

[0059] In other illustrative embodiments, the number of positioning bolts 40 passing through the connecting rod 11 and the positioning rod 12 can be adjusted according to the required support strength.

[0060] In this illustrative embodiment, the relative rotational position of the bracket 10 and the mounting base 20 is fixed by the positioning bolt 40. This structure is simple and convenient for positioning operations, but it is not limited to this. In other illustrative embodiments, other structures can also be used to fix the relative rotational position of the bracket 10 and the mounting base 20.

[0061] like Figure 1 and Figure 2 As shown in the schematic embodiment, the mounting base 20 has a mounting end face 24 parallel to its width direction W at its end along its length direction L. The mounting end face 24 is, for example, perpendicular to the length direction L of the mounting base 20, but is not limited thereto. A connecting portion 21 protrudes from the mounting end face 24. A positioning bolt 40 is inserted into the mounting base 20 from the mounting end face 24 for threaded connection with the mounting base 20. This allows for a more compact overall structure.

[0062] like Figure 1 and Figure 2 As shown, in the illustrative embodiment, the support body 13 covers the mounting end face 24. A gap is provided between the support body 13 and the mounting end face 24, allowing the mounting base 20 to rotate relative to the bracket 10 within a set angular adjustment range. The support body 13 is provided with a cavity 15 facing the mounting end face 24. A connecting rod 11 and a positioning rod 12 are provided in the cavity 15. A connecting portion 21 extends into the cavity 15 and connects to the connecting rod 11. This enhances safety and protection, and also facilitates a simple and streamlined appearance. Specifically, in this illustrative embodiment, as... Figure 2 As shown, the support body 13 has two cavities 15 facing the mounting end face 24, one above the other. A partition 17 is provided between the two cavities 15 to enhance the strength of the support body 13. A connecting rod 11 and a positioning rod 12 are respectively provided in these two cavities 15. A connecting part 21 extends into the upper cavity 15 and connects to the connecting rod 11. In other illustrative embodiments, the partition 17 may be omitted, and the two cavities 15 may be combined into one.

[0063] like Figure 1 and Figure 2As shown in the illustrative embodiment, the outer wall of the support body 13 has an operating port 16 that communicates with the cavity 15. The operating port 16 extends, for example, to the end of the support body 13 facing the mounting end face 24, but is not limited thereto. This facilitates adjustment. In the illustrative embodiment, the size of the operating port 16 can be adjusted as needed to at least meet the requirements for adjusting the angle of the X-ray tube.

[0064] In another illustrative embodiment of the support mechanism for medical X-ray imaging equipment, such as Figure 3 As shown, the support mechanism may also include a cover C for covering the operating port 16 and a housing 50 detachably connected to the mounting base 20. The cover C is connected to the housing 50. Specifically, the cover C is, for example, fixedly connected to the housing 50, but is not limited thereto. Furthermore, the cover C and the housing 50 may be, for example, of the same integrally molded structure, but are not limited thereto. The specific shape of the cover C is not limited to that shown in the figure. By providing the cover C, foreign objects can be prevented from entering the cavity 15.

[0065] In other illustrative embodiments, the cover can also be connected to the support body 13 as an independent component. The connection between the cover and the support body 13 can be, for example, but not limited to, the following:

[0066] (1) Hinged pivot connection: one end of the cover is pivotally connected to the edge of the operating port 16 through the hinge shaft, so as to realize the rotation opening and closing of the cover around the hinge shaft.

[0067] (2) The operating port 16 is provided with a flange on the edge and the cover is provided with an elastic buckle on the edge. The locking is achieved by the buckle and the flange engaging.

[0068] (3) Magnetic attraction and bonding: a first magnetic component is embedded around the operating port 16, and a second magnetic component is embedded at the corresponding position on the cover. The closure is achieved by magnetic attraction.

[0069] (4) Slide rail sliding: Slide rails are provided on both sides of the operating port 16, and sliders are provided on both sides of the cover. The sliders slide along the slide rails to realize the opening and closing of the cover.

[0070] In an illustrative embodiment, the medical X-ray imaging device is, for example, a C-arm X-ray machine, and the support 10 is, for example, the C-shaped support arm of the C-arm X-ray machine. One end of the C-shaped support arm is connected to the mounting base 20.

[0071] This utility model also provides a medical X-ray imaging device, in one illustrative embodiment of which the medical X-ray imaging device includes... Figure 1 The support structure is shown. The X-ray tube of the medical X-ray imaging device is mounted on the mounting base 20. In other illustrative embodiments, the mounting base 20 may also be part of the X-ray tube; specifically, the mounting base 20 may be, for example, a support structure for the X-ray tube, but is not limited thereto. This medical X-ray imaging device allows for easy adjustment of the X-ray tube angle.

[0072] Specifically, such as Figure 4 As shown in the illustrative embodiment, the medical X-ray imaging device is, for example, a C-arm X-ray machine, and the support 10 is, for example, the C-shaped support arm of the C-arm X-ray machine. One end of the C-shaped support arm is connected to the mounting base 20.

[0073] It should be understood that although this specification is described according to various embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0074] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. All equivalent implementation schemes or modifications made without departing from the spirit of the present utility model, such as combinations, divisions or repetitions of features, should be included within the scope of protection of the present utility model.
