Description

Technical Field

[0001] The present invention relates to the technical field of X-ray imaging equipment, and in particular to a multi-functional G-arm. Background Art

[0002] The G-Arm is an X-ray imaging device applicable to fields such as orthopedics, neurosurgery, and pain medicine. It can integrate two sets of X-ray emission and imaging devices, generate X-rays from two mutually perpendicular directions, and through an X-ray intensifying device and computer image processing, it can simultaneously perform anteroposterior and lateral exposures on the region of interest to obtain real-time anteroposterior and lateral medical images of the patient.

[0003] During the use of traditional G-arms, due to the too small opening, the G-arm cannot be positioned vertically on the operating table, and can only be inserted into the operating table from the parallel direction for work. At the same time, two people are also required to push from both sides to prevent it from tipping over. Some G-arms can perform simultaneous anteroposterior and lateral imaging, but due to the small rotation angle, three-dimensional imaging cannot be achieved. Summary of the Invention

[0004] In view of the above problems existing in the prior art, the main object of the present invention is to provide a multi-functional G-arm.

[0005] The technical solution of the present invention is as follows: A multi-functional G-arm includes an imaging main body. A connecting frame is provided on the upper surface of the imaging main body. One end of the connecting frame is fixedly connected to a bracket. A driving structure is provided inside the bracket. The bracket is rotatably connected to an outer wall C-arm. One end of the outer wall C-arm is fixedly connected to an electric push rod. The output end of the electric push rod is fixedly connected to a first flat panel detector. The outer wall C-arm is rotatably connected to an inner C-arm. One end of the inner C-arm is fixedly provided with a second electric push rod. The output end of the second electric push rod is fixedly connected to a second flat panel detector. A first X-ray tube and a second X-ray tube are fixedly provided on the inner wall surface of the inner C-arm.

[0006] As a preferred embodiment, the driving structure includes a motor. The output end of the motor is connected to a right angle reducer. A belt pulley is fixedly provided at the output end of the right angle reducer. The belt pulley is meshed with a synchronous toothed belt. The synchronous toothed belt is fixedly connected to the back surface of the outer wall C-arm.

[0007] As a preferred embodiment, a second driving structure is fixedly connected to the outer wall C-arm. The second driving structure is meshed with a second synchronous toothed belt. The second driving structure has the same structure as the driving structure.

[0008] As a preferred embodiment, the outer wall C-arm is a quarter circle, and the inner C-arm is about a half circle.

[0009] As a preferred embodiment, both ends of the synchronous toothed belt are respectively connected to both ends of the outer wall C-arm.

[0010] As a preferred embodiment, both the outer wall C-arm and the inner C-arm are provided with limiting structures.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are that through the cooperation of the outer wall C-arm and the inner C-arm to rotate, angle rotation can be performed, rotational scan images can be collected, and three-dimensional reconstruction can be carried out, improving the imaging quality and accuracy.

[0020] Embodiment

[0021] A multifunctional G-shaped arm includes an imaging main body 1. A connecting frame 2 is provided on the upper surface of the imaging main body 1. One end of the connecting frame 2 is fixedly connected to a bracket 3. A driving structure 4 is provided inside the bracket 3. The bracket 3 is rotatably connected to an outer wall C-arm 5. One end of the outer wall C-arm 5 is fixedly connected to an electric push rod 7. The output end of the electric push rod 7 is fixedly connected to a first flat panel detector 6. The outer wall C-arm 5 is rotatably connected to an inner wall C-arm 8. One end of the inner wall C-arm 8 is fixedly provided with a second electric push rod. The output end of the second electric push rod is fixedly connected to a second flat panel detector 9. A first X-ray tube 10 and a second X-ray tube 11 are fixedly provided on the inner wall surface of the inner wall C-arm 8. When in use, the driving structure 4 can drive the outer wall C-arm 5 and the inner wall C-arm 8 to rotate together, thereby changing the irradiation angle of the first flat panel detector 6. And the inner wall C-arm 8 can rotate independently and cooperate with the rotation of the outer wall C-arm 5 to achieve large-angle rotational scanning of images, so as to perform three-dimensional reconstruction and improve the imaging quality and accuracy.

[0022] The driving structure 4 includes a motor 41. The output end of the motor 41 is connected to a right-angle reducer 42. A pulley is fixedly provided at the output end of the right-angle reducer 42. The pulley is meshed with a synchronous toothed belt 43. The synchronous toothed belt 43 is fixedly connected to the back surface of the outer wall C-arm 5. With the start of the motor 41, the synchronous toothed belt 43 is driven, causing the outer wall C-arm 5 to rotate, thereby adjusting the scanning angle and position of the first flat panel detector 6.

[0023] A second drive structure 12 is fixedly connected to the outer wall C-arm 5. The second drive structure 12 is meshed and connected to a second synchronous toothed belt 13. The second drive structure 12 has the same structure as the drive structure 4. After the outer wall C-arm 5 rotates to a suitable position, the scanning angle of the first flat panel detector 6 is adjusted. Then, through the second drive structure 12, the inner C-arm 8 is rotated. As the inner C-arm 8 rotates, the second flat panel detector 9 is driven to rotate, completing the adjustment of the scanning angle of the second flat panel detector 9 and realizing a large-angle rotational scanning image.

[0024] The outer wall C-arm 5 is a quarter circle, and the inner C-arm 8 is approximately a half circle; both ends of the synchronous toothed belt 43 are respectively connected to both ends of the outer wall C-arm 5. The outer wall C-arm 5 can move in an arc along the support 3, and the inner C-arm 8 can move in an arc along the outer wall C-arm 5. By using the arc movements of both, the scanning angles of the first flat panel detector 6 and the second flat panel detector 9 are changed, and three-dimensional imaging is realized by using the different scanning angles of both.

[0025] Both the outer wall C-arm 5 and the inner C-arm 8 are provided with limiting structures. The limiting structures are that the teeth at both ends of the synchronous toothed belt 43 and the second synchronous toothed belt 13 are teeth that cannot be meshed with the pulleys, thereby realizing the limiting function.

[0026] The electric push rod 7 and the second electric push rod can be replaced by a scissor-type electric lifting table structure. The scissor-type electric lifting table structure has been applied for a patent and will not be described here. For the structure that realizes the up and down movement of the first flat panel detector 6 and the second flat panel detector 9, it can also be realized by a gear-rack and a lead screw guide rail.

[0027] Working principle:

[0028] As shown in the figure, first, driven by the motor 41, the outer wall C-arm 5 moves in an arc along the support 3, and at the same time, the inner C-arm 8 is also driven to rotate. After the position of the outer wall C-arm 5 reaches a suitable orientation, the scanning angle of the first flat panel detector 6 is fixed. Then, according to the angle of the first flat panel detector 6, the scanning angle of the second flat panel detector 9 is adjusted. Through the second drive structure 12, the inner C-arm 8 is driven to move in an arc along the outer wall C-arm 5, so that the angles of the first flat panel detector 6 and the second flat panel detector 9 can perform scans at different angles, thereby forming a three-dimensional image.

[0029] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting 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 cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
