Description

Technical Field

[0001] This application relates to the field of medical device technology, and more specifically, to an X-ray image-guided system. Background Technology

[0002] Currently, head tumors are highly prevalent, seriously threatening human health. Image-guided stereotactic gamma radiation therapy systems play a crucial role in treating brain tumors. It eliminates the need for craniotomy, using gamma rays to stereotactically destroy or inhibit tumor tissue under the guidance of an image-guided system. Its clinical indications are broad, including brain metastases, gliomas, meningiomas, pineal tumors, and pituitary adenomas.

[0003] Existing patent document CN107550508B discloses an X-ray machine in which, when the C-arm is in the first position and the adjusting arm is in the third position, the intersection of the central beam of the X-ray beam and the axis of the adjusting arm coincides with the positioning point. Thus, after switching the C-arm from the first position to the second position or vice versa, simply switching the adjusting arm between the third and fourth positions ensures that the distance between the positioning point and the X-ray detector remains at a predetermined value, improving the C-arm's operational efficiency. Furthermore, since the X-ray machine of this application does not require redefining the positioning point when switching the C-arm between the first and second positions, it reduces the radiation dose absorbed by medical personnel and patients during position adjustment.

[0004] The aforementioned device adjusts the position of the X-ray tube and X-ray detector by manually pushing the support body. This adjustment method affects the stability of the X-ray tube and X-ray detector's position and increases the difficulty of adjusting their position. Therefore, we propose an X-ray image guidance system. Utility Model Content

[0026] Please refer to the figure. This application provides an X-ray image guidance system, including a slide rail 1, which is disposed above a radiotherapy device. The slide rail 1 is arranged in a direction orthogonal to the orientation of the radiotherapy device. A sliding member 2 is slidably connected to the slide rail 1. A connecting member 3 is installed at the lower part of the sliding member 2. A frame 4 is rotatably connected to the lower part of the connecting member 3. An X-ray generator 5 and a detector 6 are fixedly installed on the frame 4. The X-ray generator 5 and the detector 6 are both fixedly installed on the frame 4 by brackets and bolts. The X-ray generator 5 and the detector 6 are arranged opposite to each other. A first drive motor 7 is installed on the connecting member 3 and is drivenly connected to the frame 4.

[0027] When radiotherapy is required, the user can move the central axis of the gantry 4 to coincide with the central axis of the cylindrical treatment cavity of the radiotherapy equipment by controlling the slider 2 to move on the slide rail 1, and drive the X-ray generator 5 and detector 6 to rotate to obtain images for guiding the radiotherapy equipment; after the radiotherapy is completed, the user can move the gantry 4 to the side of the radiotherapy equipment by controlling the slider 2 to move on the slide rail 1.

[0028] like Figure 2 As shown, a gear is fixedly connected to the output end of the first drive motor 7, and a gear ring 401 is fixedly connected inside the frame 4, with the gear meshing with the gear ring 401. An arc-shaped groove 301 is provided at the lower part of the connecting piece 3, and a bearing 8 is fixedly installed within the arc-shaped groove 301. The frame 4 is rotatably connected to the connecting piece 3 via the bearing 8. The user can control the first drive motor 7 to drive the frame 4, moving the X-ray generator 5 and detector 6 to a designated position to acquire images of the radiotherapy site.

[0029] like Figure 3As shown, the connecting piece 3 is rotatably connected to the sliding piece 2. A second drive motor 9 is fixedly mounted on the sliding piece 2, and a drive gear 10 is fixedly connected to the output end of the second drive motor 9. A driven gear 11 is fixedly connected to the upper part of the connecting piece 3, and the drive gear 10 and the driven gear 11 mesh. When the gantry 4 moves to the side of the radiotherapy equipment, the user can control the second drive motor 9 to drive the gantry 4 to rotate, adjusting the gantry 4 to a state parallel to the wall, reducing the space occupied by the gantry 4.
