Specifically, can provide the mounted position in fluting 20 for push rod 7 through setting up articulated seat 22, because articulated seat 22 is located the inner rail 10 below, be equipped with on the balancing weight 11 and hold the breach that articulated seat 22 passed through, so that balancing weight 11 passes when sliding on the inner rail 10 articulated seat 22 position is located, makes like this, and push rod 7 remains one side at balancing weight 11 all the time at the course of the work, can not take place to interfere with the motion of balancing weight 11.
Based on the same technical scheme, the application also provides a CT scanning system which comprises the CT scanning device.
In an embodiment of the present application, there is provided a CT scanning apparatus, including: a patient support for supporting a user; the scanning frame 1 is used for carrying out CT scanning; the patient support is arranged on the support seat 4, and the scanning frame 1 is connected to the support seat 4 in a sliding mode; the overturning support 14 is fixed on the installation end face, and a first end of the overturning support 14 is hinged with a first end of the support seat 4; and the push rod 7 is hinged to the overturning support 14 at one end and hinged to the supporting seat 4 at the other end, so that when the push rod 7 exerts acting force on the supporting seat 4, the angle between the overturning support 14 and the supporting seat 4 is changed, and the arrangement angle of the scanning frame 1 and the patient support is changed. Exert the effort through push rod 7 to supporting seat 4, change upset support 14 with the angle between the supporting seat 4 to the change the scan frame 1 with patient support's the angle of arranging for scan frame 1 can carry out the scanning in a plurality of directions to the patient on patient support, this CT scanning flip structure has realized adjusting upset support 14 fast conveniently with the angle between the supporting seat 4, and then adjust scan frame 1 with patient support's the purpose of arranging the angle. Meanwhile, the scanning frame 1 is connected to the supporting seat 4 in a sliding mode, so that the supporting seat 4 is not moved, and the scanning frame 1 scans different positions of a patient. Therefore, the technical problem of how to realize the scanning of the horizontal position, the vertical position or other inclination angle positions of the CT scanning frame 1 in the related technology is solved.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
