Technical Field

[0001] The utility model relates to the technical field of C-type machines, in particular to a tube adjustment structure and an X-ray machine. Background Art

[0002] The tube is the component that generates X-rays on the C-arm system. The size and intensity of the X-ray field it generates have a great impact on the system design and image quality of the C-arm. The heel effect of the anode of the tube core makes the X-ray dose at the anode end of the tube small, which usually affects the image quality after imaging of the C-arm system.

[0003] At present, the tube target angles provided by C-arm system tube suppliers range from 8 to 10 degrees. When the tube target angle selected by the C-arm system design is too small (for example, 8 degrees), after the flat panel and the tube are calibrated and centered, the X-rays generated by the tube just cover the image receiving area of ​​the flat panel detector near the anode, and the irradiation field margin is insufficient. At the same time, the radiation dose on the flat panel detector near the anode is low, and the brightness of the collected image is low.

[0004] Therefore, the prior art needs to be further developed. Utility Model Content

[0026] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0027] According to an embodiment of the utility model, a ball tube adjustment structure is provided. Figures 1 to 5 , including: a mounting base 1; a mounting box 2, the mounting box 2 is arranged on the mounting base 1, and the mounting box 2 is used to install the tube; an imaging component 4, the imaging component 4 is arranged on the mounting base 1, and the imaging component 4 is arranged corresponding to the mounting box 2 to receive the rays emitted by the tube; an adjusting component 3, the adjusting component 3 is used to adjust the relative position between the mounting box 2 and the imaging component 4, the adjusting component 3 includes a rotating structure 31 and a lifting structure 32 arranged at intervals, the rotating structure 31 is relatively rotatably connected to the mounting box 2, the mounting box 2 is liftably arranged on the lifting structure 32, and the rotating structure 31 and the lifting structure 32 are arranged at intervals; when the mounting box 2 and the rotating structure 31 rotate relative to each other, the mounting box 2 is lifted and moved along the lifting structure 32.

[0028] With the above arrangement, when the imaging effect of the rays emitted by the tube on the imaging component 4 is unclear, the relative positions of the mounting box 2 and the imaging component 4 can be adjusted by adjusting the component 3, so that one end of the mounting box 2 rotates around the rotating structure 31, and at the same time, the other end of the mounting box 2 moves up and down along the lifting structure 32, so that the X-rays emitted by the tube in the mounting box 2 are deflected until the imaging of the X-rays emitted by the tube on the imaging component 4 achieves an ideal effect, thereby solving the technical problem of low image brightness caused by insufficient radiation field margin in the related art.

[0029] Preferably, the mounting base 1 is a C-arm; the mounting box 2 and the imaging assembly 4 are respectively arranged at two ends of the C-arm.

[0030] Specifically, the imaging component 4 is a flat panel detector.

[0031] In the ball tube adjustment structure of this embodiment, see Figures 2 to 4 The rotating structure 31 has a rotating base 311, which is fixed on the mounting seat 1, and a rotating channel 310 is arranged on the rotating base 311; the mounting box 2 has a rotating shaft 21, which is arranged protruding from the surface of the mounting box 2, and is inserted into the rotating channel 310, and the rotating shaft 21 is rotatably arranged in the rotating channel 310. In this way, when the imaging effect of the rays emitted by the tube on the imaging component 4 is unclear, the mounting box 2 is rotated to rotate the mounting box 2 around the rotating shaft 21, and the X-rays emitted by the tube in the mounting box 2 are deflected until the imaging effect of the X-rays emitted by the tube on the imaging component 4 reaches an ideal effect.

[0032] Preferably, the rotating shaft 21 is a screw.

[0033] In the ball tube adjustment structure of this embodiment, see Figures 2 to 4 A fastener 22 is provided on the side of the rotating base 311 away from the installation box 2. The fastener 22 is sleeved on the outside of the rotating shaft 21 and is used to limit the relative rotation of the rotating shaft 21 and the rotating base 311. In this way, when the angle of the installation box 2 is adjusted to a position where the imaging effect of the X-rays emitted by the tube on the imaging component 4 is ideal, the fastener 22 is tightened to fix the relative position between the installation box 2 and the imaging component 4.

[0034] Preferably, the fastener 22 is a nut.

[0035] In the ball tube adjustment structure of this embodiment, see Figure 2 , Figure 5The lifting structure 32 has a lifting component 321, and the lifting component 321 includes a lifting part 3211 and a connecting part 3212. The connecting part 3212 is rotatably arranged relative to the mounting seat 1; the mounting box 2 has a connecting plate body 23, and a connecting hole 231 is arranged on the connecting plate body 23. The connecting hole 231 is used for the lifting part 3211 to pass through, so that the connecting plate body 23 is sleeved on the outside of the lifting part 3211, and the connecting plate body 23 is lifted and lowered along the lifting part 3211. In this way, when the installation box 2 rotates around the rotating shaft 21, the connecting plate body 23 at the other end of the installation box 2 moves along the lifting part 3211. Since the installation box 2 rotates around the rotating shaft 21, the connecting plate body 23 does not move in a fixed direction. At the same time, the connecting plate body 23 mounted on the lifting part 3211 has a limiting effect on the lifting part 3211 in the horizontal direction. Therefore, when the installation box 2 rotates, the connecting plate body 23 applies a force to the lifting component 321 in the horizontal direction, driving the lifting component 321 to rotate; at the same time, the connecting plate body 23 moves along the lifting part 3211 in the extension direction of the lifting part 3211.

[0036] Preferably, the lifting part 3211 is a screw.

[0037] In the ball tube adjustment structure of this embodiment, see Figure 5 The lifting structure 32 includes: a fixing component 322, which is connected to the mounting seat 1 and is provided with a first connecting channel; a connecting portion 3212 is spaced apart from the fixing component 322 and is provided with a second connecting channel; and a connecting component 323, which is inserted into the first connecting channel and the second connecting channel and is used to connect the fixing component 322 and the lifting component 321.

[0038] Preferably, the connecting component 323 is a plug screw.

[0039] In this way, the connecting component 323 connects the fixing component 322 and the lifting component 321. At the same time, the lifting component 321 can rotate around the connecting component 323. When the installation box 2 rotates and drives the connecting plate body 23 to move left and right in the horizontal direction, the lifting component 321 rotates around the connecting component 323 driven by the connecting plate body 23. When the installation box 2 stops rotating, no interaction force will be generated between the connecting plate body 23 and the lifting part 3211, thereby avoiding breakage of the connection.

[0040] In the ball tube adjustment structure of this embodiment, see Figure 2 , Figure 5A limiting portion is provided at one end of the connecting component 323, and a first locking component 3231 is provided at the other end of the connecting component 323. The first locking component 3231 cooperates with the limiting portion to fix the fixing component 322 and the lifting component. In this way, when the relative position adjustment of the installation box 2 and the imaging assembly 4 is completed, the first locking component 3231 is tightened to fix the relative position of the component 322 and the lifting component 321.

[0041] Preferably, the first locking component 3231 is a nut provided on the upper and lower sides of the connecting plate body 23 .

[0042] Preferably, the side where the connecting portion 3212 contacts the fixing member 322 is a horizontal plane, and the side where the connecting portion 3212 contacts the first locking member 3231 is a horizontal plane. In this way, the contact area between the connecting portion 3212 and the fixing member 322 and the first locking member 3231 is larger, making the connection between the connecting portion 3212 and the fixing member 322 more stable after locking and fixing.

[0043] In the ball tube adjustment structure of this embodiment, see Figure 2 , Figure 5 The lifting part 3211 is provided with a second locking member 3213, which is used to limit the movement of the connecting plate body 23 on the lifting part 3211. In this way, after the relative position adjustment of the installation box 2 and the imaging assembly 4 is completed, the second locking member 3213 is tightened to fix the position of the connecting plate body 23 on the lifting part 3211.

[0044] In the ball tube adjustment structure of this embodiment, see Figure 5 A fixing plate 11 is provided on the mounting seat 1 . The fixing plate 11 is fixed on the mounting seat 1 . The fixing plate 11 is used to fix the adjusting component 3 .

[0045] Preferably, the width of the fixing plate 11 is greater than the width of the mounting seat 1 .

[0046] In this way, the fixing plate 11 can be installed with installation boxes 2 of different sizes.

[0047] In the ball tube adjustment structure of this embodiment, see Figure 1 There are two groups of adjustment components 3, and the two groups of adjustment components 3 are arranged on both sides of the installation box 2 at intervals.

[0048] Preferably, the axes of the rotating shafts 21 on both sides of the installation box are in the same straight line. In this way, adjustment structures are provided on both sides of the installation box 2 to make the adjustment of the installation box 2 smoother. At the same time, the installation box 2 is connected to the mounting base 1 through the adjustment component 3, and the adjustment components 3 on both sides make the connection of the installation box 2 more stable.

[0049] An X-ray machine comprises: a tube adjustment structure; a base 10, the base 10 is connected to a mounting seat 1, and the base 10 is used to fix the mounting seat 1.
