Description

Technical Field

[0001] The present invention relates to the field of medical imaging technology, and particularly to an X-ray gantry structure with a stationary operation page. Background Art

[0002] X-ray gantries are usually used in medical imaging equipment, such as suspended DR, double-column DR or other DR equipment. In the existing technology, the operation page needs to rotate with the rotation of the X-ray tube, which not only prolongs the examination time and increases the risk of misoperation, but also violates the ergonomic specifications of modern medical equipment (such as the DICOM GSDF perspective stability requirement).

[0003] With the development of intelligent imaging technology, the existing hard coupling architecture can no longer meet the new technology requirements such as touch operation and voice control. Therefore, there is an urgent need for an interface adaptive decoupling technology to ensure the spatial stability of the operation interface and the consistency of the interaction logic while maintaining the movement freedom of the X-ray tube, so as to adapt to the efficient and safe operation requirements in the era of precision medicine. Summary of the Invention

An electric motor is provided inside the elbow arm, and a driving gear is provided at the output end of the electric motor. The driving gear is meshed with a driven gear, and the driven gear is fixedly connected to an elbow arm shaft. One end of the elbow arm shaft away from the driven gear is fixedly connected to a tube assembly. One side of the tube assembly is connected to an operation box through an electromagnetic rotation assembly.

[0018] Embodiment

[0019] An X-ray gantry structure with an operation page staying still includes a bent arm 1. A motor 2 is provided inside the bent arm 1. A driving gear is provided at the output end of the motor 2. The driving gear is meshed and connected to a driven gear 3. The driven gear 3 is fixedly connected to a gantry shaft 4. One end of the gantry shaft 4 away from the driven gear 3 is fixedly connected to a tube assembly. One side of the tube assembly is connected to an operation box 9 through an electromagnetic rotation assembly 8. By using the magnetic adsorption and adsorption disconnection of the electromagnetic rotation assembly 8, the operation box 9 can rotate along with the tube assembly or stay vertically still, which is convenient for viewing and use, and can avoid the situation of misreading or misoperation caused by the unstable display screen of the interface operator.

[0020] The electromagnetic rotation assembly 8 includes a disk shaft 81. One side of the disk shaft 81 is fixedly connected to the operation box 9. A bearing 82 is installed on the shaft on the other side of the disk shaft 81. A disk 84 is provided at one end of the disk shaft 81. Mounting holes are provided on the disk 84. A power-off type electromagnet 83 and a spring positioning bead 86 are installed in the mounting holes. The shaft tail end of the disk shaft 81 penetrates through the disk 84 and is connected to a round nut 85. When the power-off type electromagnet 83 is powered off, there is no current in the coil. At this time, the magnetic force is maintained by the built-in permanent magnet, so that the armature remains in the adsorbed state, making the disk 84 fit with the disk shaft 81. When powered on, the reverse magnetic field generated by the coil cancels the magnetic field of the permanent magnet, making the electromagnet lose magnetism, so that the disk 84 is separated from the disk shaft 81. When the disk 84 is separated from the disk shaft 81, the spring positioning bead 86 on the disk 84 sticks to the disk shaft 81 for positioning and reducing the frictional force at the same time.

[0021] The tube assembly includes an X-ray tube 6, a tube fixing bracket 5, and a collimator 7. The bent arm 1 is fixedly connected to the tube fixing bracket 5 through the gantry shaft 4. The X-ray tube 6 is provided inside the tube fixing bracket 5. The collimator 7 is installed at the focal position of the X-ray tube 6 for adjusting the irradiation field of the X-ray.

[0022] The shaft 81 is provided with positioning grooves, and the angle between the positioning grooves is 90 degrees, which is used for the spring positioning beads 86 to be pressed in for positioning; the operation box 9 is provided with an operation interface, and a counterweight is arranged inside the operation box 9 to increase the stability of the operation box 9.

[0023] Working principle:

[0024] As shown in the figure, the motor 2 inside the bent arm 1 drives the driving gear to drive the driven gear 3 to rotate, so that the tube assembly rotates. When the power-off type electromagnet 83 in the electromagnetic rotation assembly is energized, the power-off type electromagnet 83 in the electromagnetic rotation assembly loses magnetism, and the disc 84 is separated from the shaft 81. The gravity of the counterweight at the bottom of the operation box 9 makes the operation box 9 vertically downward, the tube rotates, and the operation box does not move.

[0025] When the system is set to cut off the power supply of the power-off type electromagnet 83, the power-off type electromagnet 83 maintains its magnetic force, the disc 84 is attached to the shaft 81, and the operation box 9 rotates with the rotation of the tube; at the same time, the operation box 9 can be rotated manually by 90°, and the spring positioning beads 86 are pressed into the positioning grooves for positioning.

[0026] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
