Technical Field

[0001] The utility model relates to a rotating mechanism of a suspension frame, and a suspension frame and a medical imaging system comprising the same. Background Art

[0002] Medical imaging systems are usually equipped with displays for human-computer interaction or image display. These displays are hung on the roof of a building, for example, by a suspension bracket to reduce the floor space. In order to facilitate the adjustment of the position and angle of the display, the suspension bracket is usually provided with a rotating mechanism so that the display can rotate or move along a circular trajectory. The rotating mechanism currently used has a complex structure and is time-consuming to assemble. Utility Model Content

[0003] The utility model aims to provide a rotation mechanism of a suspension frame, which has a simple structure and is easy to assemble.

[0004] Another object of the utility model is to provide a suspension bracket, the rotating mechanism of which has a simple structure and is easy to assemble.

[0005] Another object of the present invention is to provide a medical imaging system, wherein the rotating mechanism of the suspension frame has a simple structure and is easy to assemble.

[0006] The utility model provides a rotation mechanism of a suspension frame, which includes a first seat body, a second seat body and two axial support rolling groups. The second seat body can rotate relative to the first seat body around a rotation axis. Each axial support rolling group includes a plurality of axial support rolling bodies distributed along a circumferential direction perpendicular to the rotation axis. Each axial support rolling group is clamped between the first seat body and the second seat body along a direction parallel to the rotation axis. The two axial support rolling groups can support the second seat body along directions parallel to the rotation axis and in opposite directions, respectively, to maintain the relative positions of the first seat body and the second seat body along the rotation axis. During the rotation of the second seat body relative to the first seat body, the axial support rolling bodies can roll along the surfaces of the first seat body and the second seat body.

[0007] The rotational stability of the rotation mechanism of the suspension frame is good. The rotation mechanism has a simple structure and fewer parts, which can make the overall structure more compact, and fewer parts are conducive to reducing the assembly gap, thereby facilitating the improvement of movement accuracy, and fewer parts are also convenient for assembly.

[0008] In another exemplary embodiment of the rotation mechanism of the hanger, the first seat body has an inner cavity. The second seat body is inserted into the inner cavity. The inner surface of the first seat body facing the inner cavity is protrudingly provided with a support flange surrounding the second seat body in a circumferential direction. Two axial support rolling groups are both arranged in the inner cavity and are respectively located on both sides of the support flange in a direction parallel to the rotation axis. Hiding the axial support rolling group in the inner cavity of the first seat body can prevent interference from dust and help improve stability.

[0009] In another schematic embodiment of the rotation mechanism of the suspension bracket, the second seat body includes a main body and a matching piece. The main body includes a shaft portion. The shaft portion is inserted into the center hole of the support flange. The main body also includes a support portion. The support portion is connected to one end of the shaft portion along the rotation axis and has a first support surface opposite to the support flange along the rotation axis. One of the axial support rolling groups is clamped between the support flange and the first support surface. The matching piece is detachably connected to the other end of the shaft portion along the rotation axis and has a second support surface opposite to the support flange along the rotation axis. Another axial support rolling group is clamped between the support flange and the second support surface. The main body can be detached from the first seat body along the rotation axis parallel to the rotation axis. This facilitates assembly.

[0010] In another exemplary embodiment of the rotation mechanism of the suspension, the rotation mechanism further includes a radial support rolling group. The radial support rolling group includes a plurality of radial support rolling bodies distributed around the second seat body in the circumferential direction. The radial support rolling group is arranged on the radial inner side of the support flange and is clamped between the support flange and the second seat body in the radial direction to maintain the relative position of the first seat body and the second seat body in the radial direction. During the rotation of the second seat body relative to the first seat body, the radial support rolling body can roll along the surface of the support flange and the second seat body. This can prevent the first seat body and the second seat body from deviating in the radial direction, which is conducive to improving the stability of the rotation.

[0011] In another exemplary embodiment of the rotation mechanism of the hanger, the first seat and the second seat are both cylindrical and penetrate in a direction parallel to the rotation axis and are sleeved together to form a cable channel that allows the cable to pass through the rotation mechanism, thereby facilitating the protection of the cable and the arrangement of the cable.

[0012] In another exemplary embodiment of the rotation mechanism of the suspension frame, the axially supporting rolling body is a roller. The surface of the first seat body and the second seat body for supporting the rolling of the axially supporting rolling body is a truncated cone side surface. By supporting the rolling of the axially supporting rolling body by the truncated cone side surface, support can be provided to the second seat body in a radial direction perpendicular to the rotation axis, which is conducive to improving the stability of the rotation.

[0013] In another exemplary embodiment of the rotation mechanism of the suspension frame, the rotation mechanism further includes a hoop. The hoop is fixedly connected to the first seat body and circumferentially surrounds the second seat body to provide a braking friction force during the rotation of the second seat body relative to the first seat body. The provision of the hoop facilitates stabilizing the first seat body and the second seat body at a relative rotation angle.

[0014] The utility model also provides a suspension frame, which includes a rotating mechanism as described above. One of the first seat body and the second seat body is used to connect the support body, and the other is used to connect the object to be suspended. The rotating mechanism has a simple structure and fewer parts, which can make the overall structure more compact, and fewer parts are conducive to reducing the assembly gap, thereby facilitating the improvement of movement accuracy, and fewer parts are also convenient for assembly.

[0015] In another exemplary embodiment of the suspension frame, the suspension frame further includes a connecting seat and a cantilever. The connecting seat connects one of the first seat body and the second seat body and is used to connect the support body. The cantilever connects the other of the first seat body and the second seat body and extends in a direction away from the rotation axis, and the cantilever is used to connect the object to be suspended. The cantilever is used to expand the movable range of the object to be suspended.

[0016] In another exemplary embodiment of the suspension bracket, the first seat body is inserted into the connecting seat along the installation direction parallel to the rotation axis. A limiting edge arranged around the circumference is protruded from the outer surface of the first seat body. The limiting edge can abut against the connecting seat along the installation direction to stop the first seat body at an installation position. The connecting seat and the first seat body are fixed to each other by bolts. This facilitates accurate positioning and assembly.

[0017] In another exemplary embodiment of the suspension bracket, the suspension bracket further includes a first limiter and a second limiter. The first limiter is fixedly arranged relative to the first seat body. The second limiter is fixedly arranged relative to the second seat body. The second limiter can abut against the first limiter along the circumferential direction to limit the relative rotation range of the first seat body and the second seat body. The structure is simple and can achieve the limitation of the rotation range.

[0018] The utility model also provides a medical imaging system, which includes a medical imaging device, a suspension frame as described above, and an object to be suspended. One of the first seat and the second seat is used to connect the support body, and the other is connected to the object to be suspended. In the medical imaging system, the rotational stability of the rotation mechanism of the suspension frame is good. The rotation mechanism has a simple structure and fewer parts, which can make the overall structure more compact, and fewer parts are conducive to reducing the assembly gap, thereby facilitating the improvement of the motion accuracy, and fewer parts are also convenient for assembly.

[0019] In another exemplary embodiment of the medical imaging system, the medical imaging device is a C-arm X-ray imaging device, and the object to be suspended is a display. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings. The same reference numerals in the drawings represent components with the same structure or similar structures but the same functions.

[0065] In this document, “exemplary” means “serving as an example, instance or illustration”, and any diagram or implementation described in this document as “exemplary” should not be interpreted as a more preferred or more advantageous technical solution.

[0066] In this article, "first", "second", etc. do not indicate their importance or order, but are only used to indicate the difference between each other for the convenience of document description.

[0067] In order to make the drawings concise, each figure only schematically shows the parts related to the utility model, which do not represent the actual structure of the product.

[0068] Figure 1 The figure is a schematic structural diagram of a schematic implementation of a rotation mechanism of a suspension bracket. Figure 2 For illustration Figure 1 The use scenario of the rotating mechanism shown in FIG. Figure 2 As shown, the suspension bracket 200 includes a connection seat 71, a rotation mechanism 100 and a cantilever 72. The connection seat 71 is used, for example, to be fixedly connected to the roof of a building, such as directly connected to the top wall of an operating room or indirectly connected to the top wall of an operating room through an intermediate piece. The cantilever 72 is used to connect the object to be suspended 400. The rotation mechanism 100 connects the connection seat 71 and the cantilever 72 so that the cantilever 72 can rotate relative to the connection seat 71 around the rotation axis A. The rotation mechanism can be used for a suspension bracket of a medical imaging system, and the object to be suspended 400 is, for example, a display for displaying medical images of the medical imaging system, but is not limited thereto.

[0069] Figure 3 for Figure 1 Exploded view of the rotating mechanism shown. Figure 4 for Figure 1 A partial cross-sectional view of the rotating mechanism shown. Figure 5 for Figure 4 Exploded view of the structure shown. See also Figure 1 , Figures 3 to 5 The rotating mechanism 100 includes a first seat body 10, a second seat body 20 and two axial support rolling groups 30. In this exemplary embodiment, the second seat body 20 includes a main body 21 and a fitting 23, which are fixedly connected by bolts 91. The second seat body 20 can rotate around the rotation axis A relative to the first seat body 10.

[0070] like Figure 3 As shown, each axial support rolling group 30 includes a plurality of axial support rolling bodies 31 (distributed along a circumferential direction C perpendicular to the rotation axis A) Figure 3 In the figure, only one axial support rolling element 31 is schematically indicated for each axial support rolling element group 30. In the schematic embodiment, the number of axial support rolling elements 31 can be adjusted as required. Figure 4 As shown, each axial support rolling group 30 is sandwiched between the first seat body 10 and the second seat body 20 along a direction parallel to the rotation axis A. The two axial support rolling groups 30 can respectively support the second seat body 20 in directions parallel to the rotation axis A and in opposite directions to maintain the relative positions of the first seat body 10 and the second seat body 20 along the rotation axis A. The axis of the axial support rolling body 31 is, for example, perpendicular to the rotation axis A, but is not limited thereto. Specifically, see Figure 4The upper axial support rolling group 30 supports the second seat body 20 upward and supports the first seat body 10 downward, and the lower axial support rolling group 30 supports the first seat body 10 upward and supports the second seat body 20 downward, thereby maintaining the relative position of the first seat body 10 and the second seat body 20 along the rotation axis A.

[0071] During the rotation of the second seat body 20 relative to the first seat body 10, the axial support rolling body 31 can roll along the surfaces of the first seat body 10 and the second seat body 20. In this exemplary embodiment, the axial support rolling body 31 is a roller, but not limited thereto, in other exemplary embodiments, the axial support rolling body 31 may also be a ball.

[0072] See also Figure 2 and Figure 4 When the rotating mechanism 100 is in use, the rotation axis A is parallel to the direction of gravity ( Figure 2 and Figure 4 The gravity direction is downward), the first seat body 10 is connected to the connecting seat 71, and the second seat body 20 (in Figure 2 The cantilever 72 and the object to be suspended 400 exert force on the second seat body 20 under the action of gravity, so that the second seat body 20 tends to tilt relative to the first seat body 10, and the two axial support rolling groups 30 can respectively abut against the second seat body 20 in opposite directions parallel to the rotation axis A, so that the second seat body 20 maintains a vertical state and can remain stable when rotating relative to the first seat body 10.

[0073] The rotational stability of the rotation mechanism of the suspension frame is good. The rotation mechanism has a simple structure and fewer parts, which can make the overall structure more compact, and fewer parts are conducive to reducing the assembly gap, thereby facilitating the improvement of movement accuracy, and fewer parts are also convenient for assembly.

[0074] like Figure 3 As shown, in the exemplary embodiment, each axial support rolling group 30 further includes a cage 32, and the cage 32 is used to evenly separate the plurality of axial support rolling elements 31 one by one. This helps to improve the stability of the structure. The combination of the cage 32 and the axial support rolling element 31 is the same as the combination of the cage and the rolling element (roller or ball) in the existing bearing, and will not be repeated here.

[0075] like Figure 4As shown, in the exemplary embodiment, the first seat body 10 has an inner cavity 11. The second seat body 20 is inserted into the inner cavity 11. The inner surface of the first seat body 10 facing the inner cavity 11 is protrudingly provided with a support flange 12 surrounding the second seat body 20 along the circumferential direction C. Two axial support rolling groups 30 are both arranged in the inner cavity 11 and are respectively located on both sides of the support flange 12 along the direction parallel to the rotation axis A. Hiding the axial support rolling group 30 in the inner cavity 11 of the first seat body 10 can prevent interference from dust and help improve stability.

[0076] like Figures 3 to 5 As shown, in the exemplary embodiment, the second seat body 20 includes a main body 21 and a matching member 23. The main body 21 includes a shaft portion 211 and a support portion 212. For ease of understanding, Figure 4 The shaft portion 211 and the support portion 212 are separated by a dotted line. The shaft portion 211 is inserted into the central hole of the support flange 12. The support portion 212 is connected to one end of the shaft portion 211 along the rotation axis T parallel to the rotation axis A (i.e. Figures 3 to 5 and has a first support surface S1 (see Figure 3 and Figure 5 One of the axial support rolling groups 30 (i.e. the axial support rolling group 30 located at the lower side) is sandwiched between the support flange 12 and the first support surface S1. The fitting 23 is detachably connected to the other end of the shaft portion 211 along the rotation axis T (i.e. Figures 3 to 5 and has a second support surface S2 (see Figure 3 and Figure 5 ). Another axial support rolling group 30 (i.e., the axial support rolling group 30 located on the upper side) is sandwiched between the support flange 12 and the second support surface S2. The main body 21 can be detached from the first seat body 10 along the rotation axis T. When assembling the rotating mechanism 100, the lower axial support rolling group 30, the first seat body 10, and the upper axial support rolling group 30 are sequentially inserted into the shaft portion 211 from top to bottom, and then the fitting 23 is fixed to the upper end of the shaft portion 211 by bolts 91. This facilitates assembly.

[0077] like Figures 3 to 5 As shown, in the exemplary embodiment, the rotating mechanism further includes a radial support rolling group 40. The radial support rolling group 40 includes a plurality of radial support rolling bodies 41 ( Figure 3Only one of the radial support rolling bodies 41 is schematically indicated in the figure. In the schematic embodiment, the number of the radial support rolling bodies 41 can be adjusted as needed. The radial support rolling group 40 is arranged on the radial inner side of the support flange 12 and is radially sandwiched between the support flange 12 and the second seat body 20 to maintain the relative position of the first seat body 10 and the second seat body 20 in the radial direction. During the rotation of the second seat body 20 relative to the first seat body 10, the radial support rolling body 41 can roll along the surface of the support flange 12 and the second seat body 20. This can prevent the first seat body 10 and the second seat body 20 from deviating in the radial direction, which is conducive to improving the stability of the rotation.

[0078] like Figure 4 As shown, in the exemplary embodiment, the first seat body 10 and the second seat body 20 are both cylindrical and penetrate in a direction parallel to the rotation axis A and are mutually sleeved to form a cable channel 60 that allows the cable to pass through the rotation mechanism. This facilitates the protection of the cables and the arrangement of the cables.

[0079] Figure 6 FIG. 1 is a partial cross-sectional view of another exemplary embodiment of the rotating mechanism. Figure 1 The same or similar parts of the rotating mechanism shown are not described here in detail, and the differences are as follows. Figure 6 As shown, in this exemplary embodiment, the surface of the first seat body 10 and the second seat body 20 for supporting the rolling of the axial support rolling body 31 is a truncated cone side surface. By supporting the rolling of the axial support rolling body 31 through the truncated cone side surface, the second seat body 20 can be provided with support in the radial direction perpendicular to the rotation axis A, which is conducive to improving the stability of the rotation. In addition, in this exemplary embodiment, since the second seat body 20 is provided with support in the radial direction through the truncated cone side surface, the radial support rolling group 40 is not provided, thereby simplifying the structure.

[0080] Figure 7 FIG. 1 is a schematic diagram of the structure of another exemplary embodiment of the rotating mechanism. Figure 1 The same or similar parts of the rotating mechanism shown are not repeated here, and the difference is that the rotating mechanism further includes a hoop 51. The hoop 51 is fixedly connected to the first seat body 10 and surrounds the second seat body 20 along the circumferential direction C to provide braking friction during the rotation of the second seat body 20 relative to the first seat body 10. Figure 8 for Figure 7 The bottom view of the partial structure of the rotating mechanism shown in the figure is for the convenience of understanding the structure. Figure 8 In the figure, other structures except the hoop 51 are drawn with dotted lines. Figure 7 and Figure 8As shown, the outer surface of the first seat body 10 is protruded with a limiting edge 13 arranged around the circumferential direction C. The rotating mechanism 100 also includes a connecting flange 52, which is fixedly connected to the lower end surface of the limiting edge 13 by bolts 92. Figure 8 , the clamp 51 is Figure 8 The lower end of the clamp 51 is fixedly connected to the inner edge of the connecting flange 52, and the clamp 51 is provided with two left and right arms 512, the two arms 512 surround the second seat body 20, and the adjusting bolt 511 connects the ends of the two arms 512. By rotating the adjusting bolt 511, the distance between the ends of the two arms 512 can be adjusted, thereby adjusting the degree of compression of the two arms 512 on the second seat body 20, thereby changing the friction resistance of the second seat body 20 when rotating relative to the first seat body 10. The clamp 51 is provided to help stabilize the first seat body 10 and the second seat body 20 at a relative rotation angle.

[0081] The utility model also provides a suspension bracket, such as Figure 2 As shown, in an exemplary embodiment of the suspension bracket, the suspension bracket 200 includes a connecting seat 71, a Figure 1 The rotating mechanism 100 and a cantilever 72 are shown. The connecting seat 71 is connected to the first seat body 10 and is used to connect the support body, such as the roof of a building. The cantilever 72 is connected to the second seat body 20 and extends in a direction away from the rotation axis A. The cantilever 72 is used to connect the object to be suspended 400. The suspension frame is used as a part of a medical imaging system, and the object to be suspended 400 is, for example, a display for displaying medical images of the medical imaging system, but is not limited thereto. The rotation stability of the rotating mechanism of the suspension frame is good. The rotating mechanism has a simple structure and fewer parts, which can make the overall structure more compact, and fewer parts are conducive to reducing the assembly gap, thereby facilitating the improvement of movement accuracy, and fewer parts are also convenient for assembly.

[0082] In other exemplary embodiments, the cantilever 72 may be connected to the first base body 10 and the connecting base 71 may be connected to the second base body 20 .

[0083] In the exemplary embodiment, the first seat body 10 is inserted into the connecting seat 71 along the installation direction F parallel to the rotation axis A. Fig. 9 The outer surface of the first seat body 10 is protrudingly provided with a limiting edge 13 arranged around the circumferential direction C. The limiting edge 13 can abut against the connecting seat 71 along the installation direction F to stop the first seat body 10 at an installation position. The connecting seat 71 and the first seat body 10 are fixed to each other by bolts 93. This facilitates accurate positioning and assembly.

[0084] like Figure 2As shown, in the exemplary embodiment, the suspension bracket 200 further includes a first stopper 81 and a second stopper 82. The first stopper 81 is fixedly arranged relative to the first seat body 10, and is fixed to the stopper edge 13 of the first seat body 10 by bolts, for example. The second stopper 82 is fixedly arranged relative to the second seat body 20, and is fixed to the cantilever 72, for example. The second stopper 82 can abut against the first stopper 81 along the circumferential direction C to limit the relative rotation range of the first seat body 10 and the second seat body 20. The structure is simple and can achieve the limitation of the rotation range.

[0085] The utility model also provides a medical imaging system. In one exemplary embodiment, the medical imaging system includes a medical imaging device (not shown), Figure 2 The suspension frame 200 and an object 400 to be suspended are shown. The connecting seat 71 is used to connect a support body (the support body is, for example, the roof of a building), and the cantilever 72 is connected to the object 400 to be suspended. The medical imaging device is, for example, a C-arm X-ray imaging device, for example, a DSA or a mobile C-arm X-ray imaging device, and the object 400 to be suspended is, for example, a display, which is used to display medical images, but is not limited thereto. The medical imaging system has a good rotational stability of the rotation mechanism of the suspension frame. The rotation mechanism has a simple structure and fewer parts, which can make the overall structure more compact, and fewer parts are conducive to reducing the assembly gap, thereby facilitating the improvement of movement accuracy, and fewer parts are also convenient for assembly.

[0086] It should be understood that although this specification is described according to various embodiments, not every embodiment contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
