Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a medical X-ray six-dimensional bed. Background Technology

[0002] The medical six-dimensional bed is a primary device for patient immobilization during radiography or treatment, exposing the lesion area and facilitating precise treatment by doctors. It is a new type of treatment bed capable of precise patient positioning with six degrees of freedom, avoiding the problem of reduced treatment effectiveness due to patient positioning errors. In addition to the linear movement in three directions (left-right (X-axis), front-back / head-to-feet (Y-axis), and up-down (Z-axis)) of ordinary treatment beds, the medical six-dimensional bed also has the function of rotational movement along the X, Y, and Z axes. This allows for flexible adjustment of patient positioning with six degrees of freedom, correcting positioning errors, achieving precise positioning, reducing radiation dose deviation, and significantly improving treatment accuracy. Currently, there are relatively few types of six-dimensional beds available, and those that exist generally suffer from cumbersome adjustment mechanisms and low adjustment flexibility.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0009] Please see Figure 1-7This utility model provides a medical X-ray six-dimensional bed, including a fixed base 1. A rotating base support 4 is fixedly connected to the upper surface of the fixed base 1 by bolts. An external gear disk 5 is provided at the upper edge of the rotating base support 4. A lifting system mounting base 3 is rotatably connected to the upper end of the rotating base support 4 through a slewing bearing. A first motor assembly 2 is provided on one side of the lifting system mounting base 3. The power output end of the first motor assembly 2 meshes with the external gear disk 5 through a rotating gear 6. The fixed base 1 is fixedly connected to the external mounting base by bolts to ensure the overall equipment is installed firmly. The above components constitute the base rotation system structure. When the six-dimensional bed needs to rotate horizontally, the power generated by the first motor assembly 2 is transmitted to the external gear disk 5 through the rotating gear 6. Through the rotational connection between the lifting system mounting base 3 and the rotating base support 4, the lifting system mounting base 3 is driven to rotate relative to the rotating base support 4, thereby driving the overall structure to rotate horizontally. The first motor assembly 2 consists of a motor, a reducer, an electromagnetic brake, and an encoder. The upper surface of the lifting system mounting base 3 is provided with left and right lifting fixing columns 7. The left and right lifting fixing columns 7 are slidably connected to left and right lifting sliding columns 8 and lifting center column 9 via lifting sliding rail assembly 10. The left and right lifting fixing columns 7 are provided with a second motor assembly 11. The lifting center column 9 is provided with a lifting screw assembly 13. The power output end of the second motor assembly 11 cooperates with the lifting screw assembly 13 through a lifting gear set 12. The upper end of the lifting center column 9 is rotatably connected to a transverse motion mounting plate 14 through a joint bearing. The two sides of the lifting center column 9 are respectively provided with a pitch motion mechanism and a horizontal motion mounting plate 14. The flipping motion mechanism, consisting of the above components, forms a lifting system structure. When the height of the six-dimensional bed needs to be adjusted, the power generated by the second motor assembly 11 is transmitted to the lifting screw assembly 13 through the lifting gear set 12. The lifting screw assembly 13 is fixedly connected to the lifting center column 9. The lifting center column 9 is slidably connected to the left and right lifting slide columns 8 and the left and right lifting fixed columns 7 through the lifting slide rail assembly 10, thereby driving the lifting center column 9 and the transverse motion mounting plate 14 to adjust the height relative to the lifting system mounting base 3, thus adjusting the height of the six-dimensional bed. The second motor assembly 11 consists of a motor, a reducer, an electromagnetic brake, and an encoder. The pitch motion mechanism includes a third motor assembly 17, which is rotatably connected to the upper outer side of the lifting center column 9 via a rotating shaft. A guide rod 16, a pitch screw assembly 19, and a pitch slide rail assembly 20 are rotatably connected to the lower surface of the lateral motion mounting plate 14 at a position corresponding to the third motor assembly 17 via a pitch joint 15. The third motor assembly 17 is slidably connected to the guide rod 16 and the pitch slide rail assembly 20. The power output end of the third motor assembly 17 engages with the pitch screw assembly 19 via a pitch gear set 18. These components constitute the pitch system structure. The power generated by 17 is transmitted to the pitch screw assembly 19 through the pitch gear set 18, which drives the third motor assembly 17 to slide up and down along the guide rod 16 and the pitch slide rail assembly 20. Since the third motor assembly 17 is rotatably connected to the lifting center column 9 through the rotating shaft, and the guide rod 16, the pitch screw assembly 19 and the pitch slide rail assembly 20 are rotatably connected to the transverse motion mounting plate 14 through the pitch joint 15, the transverse motion mounting plate 14 is driven to pitch adjust under the support of the lifting center column 9, thereby driving the six-dimensional bed surface to pitch adjust. The third motor assembly 17 consists of a motor, a reducer, an electromagnetic brake and an encoder. The flipping motion mechanism includes a fourth motor assembly 24, which is fixedly connected to the upper inner side of the lifting center column 9. A horizontal flipping frame 21 is fixedly connected to the lower surface of the horizontal motion mounting plate 14 at a position corresponding to the fourth motor assembly 24. An internal gear ring 22 is provided on the inner surface of the horizontal flipping frame 21. The power output end of the fourth motor assembly 24 meshes with the internal gear ring 22 through a flipping gear 23. The above components constitute a flipping system structure. The power generated by the fourth motor assembly 24 is transmitted to the horizontal flipping frame 21 through the meshing of the flipping gear 23 and the internal gear ring 22. The horizontal flipping frame 21 is fixedly connected to the horizontal motion mounting plate 14, and the fourth motor assembly 24 is fixedly connected to the lifting center column 9, thereby driving the horizontal motion mounting plate 14 to adjust its flipping angle under the support of the lifting center column 9, thereby driving the six-dimensional bed surface to adjust its flipping angle. The fourth motor assembly 24 consists of a motor, a reducer, an electromagnetic brake, and an encoder. The upper surface of the transverse motion mounting plate 14 is slidably connected to an upper tray 26 via a slide rail. The upper tray 26 contains a fifth motor assembly 27. A transverse rack 25 is located on the upper surface of the transverse motion mounting plate 14 at a position corresponding to the fifth motor assembly 27. The fifth motor assembly 27 meshes with the transverse rack 25 via a transverse gear 28. The above components constitute a transverse motion system structure. The power of the fifth motor assembly 27 is transmitted to the upper tray 26 through the meshing of the transverse gear 28 and the transverse rack 25. Since the upper tray 26 is slidably connected to the transverse motion mounting plate 14 via a slide rail, it is driven to perform transverse motion adjustment under the support of the transverse motion mounting plate 14, thereby driving the six-dimensional bed surface to perform transverse motion adjustment. The fifth motor assembly 27 consists of a motor, a reducer, an electromagnetic brake, and an encoder. The upper surface of the upper tray 26 is slidably connected to a lower frame 34 via a lower guide rail assembly 37. The upper surface of the lower frame 34 is interactively connected to an upper frame 29 via an upper guide rail assembly 30. A sixth motor assembly 33 is provided on the upper surface of the upper tray 26. A drive rack 32 is provided on the inner side of the upper frame 29 at a position corresponding to the sixth motor assembly 33. One power output end of the sixth motor assembly 33 meshes with the drive rack 32 via a drive gear 31. A driven rack 36 is provided on the inner side of the lower frame 34. The upper frame 29 meshes with the driven rack 36 via a driven gear 35. The upper surface of 29 is provided with a bed board assembly 38. The above-mentioned assembly constitutes a longitudinal motion system structure. The power of the sixth motor assembly 33 is driven by the meshing of the driving gear 31 and the driving rack 32 and the meshing of the driven gear 35 and the driven rack 36, which drives the upper frame 29 to move relative to the upper tray 26 under the support of the upper guide rail assembly 30. At the same time, due to the meshing of the driven gear 35 and the driven rack 36, the lower frame 34 is driven to move relative to the upper tray 26 under the support of the lower guide rail assembly 37, thereby longitudinally adjusting the bed board assembly 38 of the six-dimensional bed. The sixth motor assembly 33 consists of a motor, a reducer, an electromagnetic brake, and an encoder.
