[0033] It should be noted that the features in the embodiments of the present utility model can be combined with each other without conflict.

[0034] Please refer to Figures 1 to 3, in the embodiment of the present application, a C-arm sliding clamping device 10 is provided. The C-arm sliding clamping device 10 can be used to install a diagnostic device for medical diagnosis and can drive the diagnostic device to move to facilitate a comprehensive detection and diagnosis of a patient. Among them, the C-arm sliding clamping device 10 provided in this embodiment can improve the technical problem that after the C-arm 11 installation form in the prior art is used for a long time on the sliding track, gaps will be generated, resulting in jitter during movement and affecting the quality of the contrast image.

[0035] In this embodiment, please refer to Figure 1 and Figure 2 , the C-arm sliding clamping device 10 includes a C-arm 11, a bearing body 100, and a first sliding clamping structure. The C-arm 11 includes an arm body 12 and two protruding parts 13; the arm body 12 is bent into a C shape, and the two protruding parts 13 are spaced apart on one side of the arm body 12. The two protruding parts 13 both extend along the arm body 12 to form a C shape, and a mating groove 14 is formed between the two protruding parts 13. In this embodiment, two protruding parts 13 are provided on both opposite sides of the arm body 12 to form mating grooves 14 on both opposite sides of the arm body 12.

[0036] The C-arm 11 is used to carry the above-mentioned diagnostic device to drive the diagnostic device to move when the C-arm 11 moves. The first sliding clamping structure includes two first support seats 210, two first wheel sets 220, and two first elastic members 230; the two first wheel sets 220 are spaced apart on the bearing body 100, and the two first wheel sets 220 clamp one of the protruding parts 13; the two first support seats 210 are fixedly connected to the bearing body 100 and respectively correspond to the two first wheel sets 220; the two first elastic members 230 are respectively arranged corresponding to the two first wheel sets 220, and both ends of the first elastic member 230 respectively abut against the corresponding first wheel set 220 and the first support seat 210 to apply an elastic acting force to the first wheel set 220 toward one side of the other first wheel set 220.

[0037] It should be noted that the two first elastic members 230 are respectively arranged corresponding to the two first wheel sets 220 means that one of the first elastic members 230 is clamped between one of the first wheel sets 220 and the corresponding first support seat 210, and the other first elastic member 230 is clamped between the other first wheel set 220 and the corresponding first support seat 210; thus, the two first elastic members 230 can respectively provide elastic acting forces to the two first wheel sets 220 so that the two first wheel sets 220 have a tendency to approach each other.

[0038] Among them, when the C-arm 11 is driven to move, the first wheel set 220 can move relative to the C-arm 11 in a rolling manner. At the same time, the two first wheel sets 220 provide a clamping effect on the C-arm 11. As described above, due to the arrangement of the two first elastic members 230, the two first elastic members 230 respectively apply elastic acting forces to the two first wheel sets 220, so that the two first wheel sets 220 tend to approach each other, which can avoid the formation of a gap between the first wheel set 220 and the convex portion 13. Furthermore, it can improve the technical problem that in the prior art, after the sliding track of the installation form of the C-arm 11 is used for a long time, a gap will be generated, resulting in jitter during movement and affecting the quality of the fluoroscopic image.

[0039] In this embodiment, the first wheel set 220 includes a first support wheel 221 and a first support shaft 222. Two spaced mounting holes 110 are formed on the bearing body 100, and the first support shaft 222 is disposed in the mounting hole 110; the first support wheel 221 is disposed at one end of the first support shaft 222, and the two first support wheels 221 jointly clamp the convex portion 13. The C-arm sliding clamping device 10 further includes a bushing 240. The bushing 240 is sleeved on the first support shaft 222, and a mounting post 241 extending toward the first support seat 210 is formed on the bushing 240, and the first elastic member 230 is sleeved on the mounting post 241.

[0040] Among them, the first wheel set 220 further has a locking member. The locking member is screwed in from the end of the first support shaft 222 away from the first support wheel 221, so that the first support shaft 222 is locked on the bearing body 100. Specifically, a limiting portion 242 abutting against the bearing body 100 is provided on the bushing 240. When the bushing 240 is sleeved on the first support shaft 222, the bushing 240 and the first support wheel 221 are located on opposite sides of the bearing body 100, and the limiting portion 242 abuts against the bearing body 100; that is to say, the diameter of the bushing 240 at the limiting portion 242 is larger than the aperture of the mounting hole 110, so that the limiting portion 242 can abut against the opening of the mounting hole 110. When the locking member is screwed in, the locking member abuts against the bushing 240, so that the limiting portion 242 of the bushing 240 abuts against the bearing body 100, and the locking of the first support shaft 222 can be achieved.

[0041] It should be noted that when the first wheel set 220, the bushing 240 and the first elastic member 230 are assembled, the first elastic member 230 provides an elastic pre-tightening force to the bushing 240, and then the elastic pre-tightening force is transmitted to the first support shaft 222 through the bushing 240, so that a radial acting force can be applied to the first support shaft 222, which can make the first support wheel 221 stably support on the convex portion 13 and ensure that the two first support wheels 221 stably clamp the convex portion 13.

[0042] Further, an avoidance hole 211 corresponding to the mounting post 241 is formed in the first support base 210, and one end of the mounting post 241 extends into the avoidance hole 211. By providing the avoidance hole 211, when the first elastic member 230 provides an elastic acting force to the bushing 240 and causes the bushing 240 to displace, the movement of the bushing 240 can be avoided through the avoidance hole 211. Furthermore, it is convenient for the first elastic member 230 to apply a pre-tightening force to the first wheel set 220, ensuring that the two first wheel sets 220 can clamp the convex portion 13.

[0043] In addition, the aperture of the mounting hole 110 is larger than the diameter of the first support shaft 222. Setting the space of the mounting hole 110 to be larger than the diameter of the first support shaft 222 can also facilitate the radial displacement of the first support shaft 222, so that under the elastic pre-tightening force of the first elastic member 230, the first support wheel 221 can be adjusted to clamp the convex portion 13.

[0044] Optionally, the first elastic member 230 is a disc spring.

[0045] In this embodiment, please refer to Figure 1 and Figure 3 For further improving the clamping of the C-arm 11, the C-arm sliding clamping device 10 further includes a second sliding clamping structure 300. The second sliding clamping structure 300 includes two second support bases 320, two second wheel sets 310, and two second elastic members 340. The two second support bases 320 are both connected to the bearing body 100 through pins 120, and the two second support bases 320 are respectively located on opposite sides of the arm body 12. The two second wheel sets 310 are respectively arranged on the two second support bases 320, and the two second wheel sets 310 clamp the arm body 12. The two second elastic members 340 are respectively arranged corresponding to the two second support bases 320, and the second elastic members 340 are pressed between the corresponding second support bases 320 and the carrier to provide an elastic acting force towards the arm body 12 to the second support bases 320.

[0046] By providing the two second elastic members 340, a force that makes the two second wheel sets 310 approach each other can be applied to the two second wheel sets 310, so that the two second wheel sets 310 can stably clamp the arm body 12, further improving the clamping effect provided to the C-arm 11, and further improving the technical problem in the prior art that after the C-arm 11 installation form is used for a long time on the sliding track, gaps will be generated, resulting in jitter during movement and affecting the quality of the fluoroscopic image.

[0047] Among them, the second round group 310 includes a second support wheel 311 and a second support shaft 312. The second support shaft 312 is connected to the second support seat 320, the second support wheel 311 is connected to the second support shaft 312, and the second support wheel 311 is fitted into the fitting groove 14. The two second support wheels 311 clamp the arm main body 12.

[0048] In this embodiment, the second elastic member 340 is sleeved on the pin 120. On the one hand, the pin 120 can be used to realize the connection between the second support seat 320 and the bearing main body 100. On the other hand, the pin 120 can also improve the stability of the second elastic member 340 and prevent the second elastic member 340 from shifting and failing.

[0049] Optionally, in this embodiment, the second elastic member 340 is a disc spring.

[0050] Based on the above-provided C-arm sliding clamping device 10, a medical diagnostic device is further provided in this embodiment. The medical diagnostic device adopts the above C-arm sliding clamping device 10. Therefore, the medical diagnostic device can solve the technical problem in the prior art that after the C-arm 11 is used for a long time in the sliding track, gaps will be generated, resulting in jitter during movement and affecting the quality of the contrast image.

[0051] In summary, in the C-arm sliding clamping device 10 and the medical diagnostic device, during the movement of the C-arm 11, the two first round groups 220 can provide a clamping effect on the C-arm 11. At the same time, the relative movement of the C-arm 11 can be realized by the rolling of the two first round groups 220. Among them, since the first elastic member 230 applies an elastic force towards the other first round group 220 to the first round group 220, the two first round groups 220 have a tendency to move closer to each other, and thus can ensure that the two first round groups 220 stably clamp the convex portion 13, can provide a stable clamping effect on the C-arm 11, can avoid the generation of gaps in the case of long-term use, and thus achieve the improvement of the technical problem in the prior art that after the C-arm 11 is used for a long time in the sliding track, gaps will be generated, resulting in jitter during movement and affecting the quality of the contrast image. Further, by providing the two second elastic members 340, a force that makes the two second round groups 310 move closer to each other can be applied to the two second round groups 310, so that the two second round groups 310 can stably clamp the arm main body 12, can further enhance the clamping effect provided to the C-arm 11, and further improve the technical problem in the prior art that after the C-arm 11 is used for a long time in the sliding track, gaps will be generated, resulting in jitter during movement and affecting the quality of the contrast image.

[0052] The above are only specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claimed rights.
