Description

Technical Field

[0001] This utility model relates to the field of X-ray imaging equipment technology, specifically a multifunctional G-arm. Background Technology

[0002] The G-arm is an X-ray imaging device suitable for fields such as orthopedics, neurosurgery, and pain management. It integrates two sets of X-ray emission and imaging devices into one unit, generating X-rays from two mutually perpendicular directions. Through X-ray intensification equipment and computer image processing, it can simultaneously perform anteroposterior and lateral exposure imaging of the region of interest, obtaining real-time anteroposterior and lateral medical images of the patient.

[0003] Traditional G-arms, due to their small opening, cannot be vertically positioned onto the operating table. They must be inserted horizontally, requiring two people to push them from both sides to prevent tipping. Some G-arms can simultaneously provide anteroposterior and lateral imaging, but due to their small rotation angle, they cannot achieve three-dimensional imaging. Utility Model Content

[0016] 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.

[0017] Please refer to 1-3. One embodiment of this utility model is provided: a multifunctional G-arm, including an image body 1, a connecting frame 2 on the upper surface of the image body 1, a bracket 3 fixedly connected to one end of the connecting frame 2, a driving structure 4 inside the bracket 3, an outer wall C-arm 5 rotatably connected to the bracket 3, an electric push rod 7 fixedly connected to one end of the outer wall C-arm 5, a first flat panel detector 6 fixedly connected to the output end of the electric push rod 7, an inner C-arm 8 rotatably connected to the outer wall C-arm 5, a second electric push rod fixedly connected to one end of the inner C-arm 8, a second flat panel detector 9 fixedly connected to the output end of the second electric push rod, and a first X-ray tube 10 and a second X-ray tube 11 fixedly provided on the inner wall surface of the inner C-arm 8. In use, the outer wall C-arm 5 and the inner C-arm 8 can be rotated together by the driving structure 4, thereby changing the illumination angle of the first flat panel detector 6. The inner C-arm 8 can also rotate independently, cooperating with the rotation of the outer wall C-arm 5 to achieve large-angle rotational scanning of images, thereby performing three-dimensional reconstruction and improving imaging quality and accuracy.

[0018] The drive structure 4 includes a motor 41, the output end of which is connected to a right-angle reducer 42. The output end of the right-angle reducer 42 is fixedly provided with a pulley, which is meshed with a synchronous toothed belt 43. The synchronous toothed belt 43 is fixedly connected to the back of the outer wall C-arm 5. As the motor 41 starts, it drives the synchronous toothed belt 43, causing the outer wall C-arm 5 to rotate, thereby adjusting the scanning angle and position of the first flat panel detector 6.

[0019] A second drive structure 12 is fixedly connected to the outer wall C-arm 5. The second drive structure 12 is engaged with the 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, the inner C-arm 8 is rotated through the second drive structure 12. As the inner C-arm 8 rotates, the second flat panel detector 9 is driven to rotate, thus completing the scanning angle adjustment of the second flat panel detector 9 and realizing a large-angle rotational scanning image.

[0020] The outer wall C-arm 5 is a quarter circle, and the inner C-arm 8 is about half a circle. The two ends of the synchronous toothed belt 43 are connected to the two ends of the outer wall C-arm 5 respectively. 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 movement of the two, the scanning angle of the first flat plate detector 6 and the second flat plate detector 9 can be changed, and three-dimensional imaging can be achieved by using the different scanning angles of the two.

[0021] Both the outer wall C-arm 5 and the inner C-arm 8 are equipped with a limiting structure. The limiting structure is that the teeth at both ends of the synchronous toothed belt 43 and the second synchronous toothed belt 13 are teeth that cannot mesh with the pulley, thereby realizing the limiting function.

[0022] The electric push rod 7 and the second electric push rod can be replaced by a scissor-type electric lifting platform structure. The scissor-type electric lifting platform structure has been patented and will not be described here. For the structure that enables the first flat plate detector 6 and the second flat plate detector 9 to move up and down, it can also be achieved by a gear rack and a lead screw guide rail.

[0023] Working principle:

[0024] As shown in the figure, firstly, driven by the motor 41, the outer wall C-arm 5 moves in an arc along the bracket 3, which also drives the inner C-arm 8 to rotate. After the outer wall C-arm 5 reaches the appropriate position, the scanning angle of the first flat panel detector 6 is fixed. Then, based on 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 achieve scanning at different angles, thereby forming a three-dimensional image.
