Description

Technical Field

[0001] This utility model relates to the field of medical imaging technology, specifically to an X-ray bull's head structure that keeps the operation page stationary. Background Technology

[0002] X-ray tubes are commonly used in medical imaging equipment, such as suspended DR, dual-column DR, or other DR devices. Existing operating screens need 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 viewing angle stability requirements).

[0003] With the development of intelligent imaging technology, the existing rigidly coupled architecture can no longer meet the needs of new technologies such as touch operation and voice control. Therefore, there is an urgent need for an interface adaptive decoupling technology that can maintain the freedom of X-ray tube movement while ensuring the spatial stability of the operating interface and the consistency of interaction logic, so as to adapt to the efficient and safe operation requirements of the precision medicine era.

[0006] Preferably, the electromagnetic rotation assembly includes a disc shaft, an operation box is fixedly connected to one side of the disc shaft, a bearing is installed on the shaft on the other side of the disc shaft, a disc is provided at one end of the disc shaft, a mounting hole is provided on the disc, a de-energized electromagnet and a spring positioning ball are installed in the mounting hole, and a round nut is connected through the disc at the tail end of the disc shaft.

[0007] Preferably, the X-ray tube assembly includes an X-ray tube, a tube holder, and a beam limiter. The curved arm is fixedly connected to the tube holder via a curved arm shaft. The X-ray tube is housed inside the tube holder, and the beam limiter is installed at the focal position of the X-ray tube.

[0008] Preferably, the disc shaft is provided with positioning grooves, and the angle between the positioning grooves is ninety degrees.

[0009] Preferably, the operation box is provided with an operation interface, and the operation box is provided with a counterweight.

[0010] Compared with the prior art, the beneficial effects of this utility model are: by using the electromagnetic rotating component, the gravity of the counterweight at the bottom of the operating box makes the operating box vertically downward, the tube rotates, and the operating box remains stationary, which is easy to view and use, and avoids misreading or misoperation caused by the instability of the display screen of the interface operator. Doctors do not need to twist their necks to look at the screen and can operate comfortably while standing, reducing human factors risks.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0015] Please refer to 1-2. One embodiment of this utility model is provided: an X-ray bull's head structure with a stationary operating screen, including a curved arm 1. A motor 2 is installed inside the curved arm 1. The output end of the motor 2 is provided with a drive gear, which meshes with a driven gear 3. The driven gear 3 is fixedly connected to a curved arm shaft 4. The end of the curved arm shaft 4 away from the driven gear 3 is fixedly connected to an X-ray tube assembly. One side of the X-ray tube assembly is connected to an operating box 9 through an electromagnetic rotating component 8. By utilizing the magnetic attraction and disengagement of the electromagnetic rotating component 8, the operating box 9 can rotate with the X-ray tube assembly or remain vertically stationary, which is convenient for viewing and use and avoids misreading or misoperation caused by the instability of the display screen of the interface operator.

[0016] The electromagnetic rotating assembly 8 includes a disc shaft 81, with an operating box 9 fixedly connected to one side of the disc shaft 81, and a bearing 82 mounted on the shaft on the other side of the disc shaft 81. One end of the disc shaft 81 has a disc 84 with a mounting hole. A de-energized electromagnet 83 and a spring positioning bead 86 are installed in the mounting hole. The tail end of the disc shaft 81 passes through the disc 84 and is connected to a round nut 85. When the de-energized electromagnet 83 is de-energized, there is no current in its coil. At this time, the built-in permanent magnet maintains the magnetic force, keeping the armature in an attracted state, thus keeping the disc 84 in contact with the disc shaft 81. When energized, the reverse magnetic field generated by the coil cancels the magnetic field of the permanent magnet, causing the electromagnet to lose its magnetism and separating the disc 84 from the disc shaft 81. When the disc 84 separates from the disc shaft 81, the spring positioning bead 86 on the disc 84 springs against the disc shaft 81, serving for positioning and reducing friction.

[0017] The X-ray tube assembly includes an X-ray tube 6, a tube holder 5, and a beam limiter 7. The curved arm 1 is fixedly connected to the tube holder 5 via a curved arm shaft 4. The X-ray tube 6 is located inside the tube holder 5. The beam limiter 7 is installed at the focal position of the X-ray tube 6 to adjust the X-ray irradiation field.

[0018] The disc shaft 81 is provided with a positioning groove, and the angle between the positioning grooves is 90 degrees, which is used for the spring positioning ball 86 to be pressed into the positioning. The operation box 9 is provided with an operation interface, and the operation box 9 is provided with a counterweight, which increases the stability of the operation box 9.

[0019] Working principle:

[0020] As shown in the figure, the motor 2 inside the curved arm 1 drives the active gear to drive the driven gear 3 to rotate, causing the X-ray tube assembly to rotate. When the system is set to be powered on by the de-energized electromagnet 83, the de-energized electromagnet 83 in the electromagnetic rotation assembly loses its magnetism, the disc 84 separates from the disc shaft 81, and the gravity of the counterweight at the bottom of the operating box 9 makes the operating box 9 vertically downward, the X-ray tube rotates, and the operating box remains stationary.

[0021] When the system is set to de-energize the electromagnet 83, the electromagnet 83 maintains its magnetic force, the disc 84 is in contact with the disc shaft 81, and the operating box 9 rotates with the rotation of the ball tube; at the same time, the operating box 9 can be manually rotated 90°, and the spring positioning bead 86 is pressed into the positioning groove for positioning.
