Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a vertical suspended CT scanning device. Background Technology

[0002] Traditional CT (Computed Tomography) scanning equipment consists of a gantry (containing a rotatable X-ray source and X-ray detector), a scanning bed, an operating console, and auxiliary systems. During the scan, the gantry rotates in a fixed position, while the patient lies horizontally on the scanning bed, which supports the patient's horizontal movements. However, due to its large size and footprint, this equipment is inconvenient to use.

[0041] like Figures 1-6 As shown, in this embodiment, the vertical suspended CT scanning device includes a CT scanner 1, a fixing component 2, a linear telescopic mechanism 3, an adjustment mechanism 4, and a mounting frame 5. The CT scanner 1 has a scanning area 11, which is used to accommodate the object being scanned; in some embodiments, the object being scanned can be a human body. The fixing component 2 includes a support rod 21 and a fixing seat 22. The fixing seat 22 is located above the CT scanner 1, and the support rod 21 is mounted on the CT scanner 1. The linear telescopic mechanism 3 includes a first telescopic component 31 and a second telescopic component 32. The fixing seat 22, the first telescopic component 31, the second telescopic component 32, and the support rod 21 are arranged sequentially from the inside to the outside along the radial direction of the scanning area 11. The fixed end of the first telescopic component 31 is connected to the fixing seat 22, the telescopic end of the first telescopic component 31 is connected to the fixed end of the second telescopic component 32, and the telescopic end of the second telescopic component 32 is connected to the support rod 21. The adjustment mechanism 4 includes multiple universal adjustment components 41. Along the circumferential direction of the CT scanner 1, the multiple universal adjustment components 41 are arranged in a divergent manner relative to the central axis of the scanning area 11. Each universal adjustment component 41 has a second end and a first end opposite to the second end for rotatably connecting with the fixed base 22. The mounting bracket 5 is used to be installed on the ceiling of the room, and the mounting bracket 5 is rotatably connected to the second end of the universal adjustment component 41.

[0042] Specifically, the CT scanner 1 has a ring-shaped structure and is in a horizontal position, meaning the central axis of the scanning area 11 of the CT scanner 1 is perpendicular to the horizontal plane. The object being scanned is located within the scanning area 11, and the CT scanner 1 scans and inspects the object. A support rod 21 is fixedly installed on the outer wall of the CT scanner 1. A mounting base 22 is located directly above the scanning area 11 and is used to fix the adjustment mechanism 4. The first telescopic component 31 and the second telescopic component 32 can be driven by a servo cylinder or other drive source for extension and retraction. The first telescopic component 31 is mounted on the mounting base 22, and the second telescopic component 32 is mounted on the telescopic end of the first telescopic component 31. The first telescopic component 31 drives the second telescopic component 32 to move along the vertical height direction when the object being scanned is standing, and the second telescopic component 32 drives the CT scanner 1 to move along the vertical height direction when the object being scanned is standing, thereby achieving vertical scanning by the CT scanner 1. The fixed base 22, the first telescopic component 31, the second telescopic component 32, and the support rod 21 are arranged sequentially from the inside to the outside along the radial direction of the scanning area 11, making the overall structure of the device more compact. The mounting frame 5 is located above the fixed base 22 and is fixedly installed on the ceiling of the room, so that the CT scanner 1 is in a vertical hanging state, saving floor installation space. The overall installation space is smaller, which is more in line with the development trend of miniaturization of medical equipment and has a better visual appeal. The adjustment mechanism 4 is set between the mounting frame 5 and the fixed base 22. The universal adjustment component 41 can be set as a drive source such as a servo electric cylinder for extension and retraction. There are multiple universal adjustment components 41, which are arranged in a divergent manner along the circumference of the CT scanner 1. Under the linkage of multiple universal adjustment components 41, the CT scanner 1 can achieve six degrees of freedom of movement.

[0043] The working principle of this vertically mounted CT scanner is as follows: First, the CT scanner 1 is installed on the ceiling of the room via the mounting bracket 5, in a horizontally vertical suspended state. Then, the subject stands within the scanning area 11 of the CT scanner 1. Driven by the linear telescopic mechanism 3, the CT scanner 1 moves a large distance along the vertical height of the subject, allowing it to scan the subject from head to toe. Simultaneously, under the action of the adjustment mechanism 4, the fixed base 22 can swing freely relative to the horizontal plane, thereby enabling the CT scanner 1 to perform six degrees of freedom of motion, covering the scanning needs of the entire body of the subject, with high flexibility.

[0044] Furthermore, continue to refer to Figures 1-6The universal adjustment assembly 41 includes a first linear drive source 411, a first rotating member 412, and a second rotating member 413. The first end of the first linear drive source 411 is connected to the first rotating member 412, which is mounted on a fixed base 22. The second end of the first linear drive source 411 is connected to the second rotating member 413, which is mounted on a mounting frame 5. Specifically, the first rotating member 412 and the second rotating member 413 are configured as hinges or universal joints. The first linear drive source 411 can be configured as a servo electric cylinder. The mounting frame 5 remains stationary. Under the driving action of the first linear drive source 411, the fixed base 22, the linear telescopic mechanism 3 below the fixed base 22, and the CT scanner 1 move relative to the mounting frame 5. Simultaneously, the rotation of the first rotating member 412 and the second rotating member 413 enables the CT scanner 1 to perform six degrees of freedom motion.

[0045] Preferably, there are multiple linear telescopic mechanisms 3, which are spaced apart along the circumference of the CT scanner 1 to ensure that the CT scanner 1 can stably perform large-stroke movements along the vertical height of the scanned object, resulting in high reliability.

[0046] Furthermore, continue to refer to Figures 1-6 The vertical CT scanning device also includes a guide assembly 6, which includes a sliding seat 61 and a guide rail 62. The guide rail 62 is disposed on the support rod 21, and the sliding seat 61 is disposed on the second telescopic assembly 32, with the sliding seat 61 slidably connected to the guide rail 62. Specifically, the guide rail 62 extends along the length of the support rod 21 and is fixedly installed on one side of the support rod 21. The sliding seat 61 is fixedly installed on one side of the second telescopic assembly 32, and is disposed on the guide rail 62, allowing it to slide along the guide rail 62. The guide assembly 6 provides a guiding function, ensuring that the CT scanner 1 can move stably along the vertical height of the scanned object.

[0047] Furthermore, continue to refer to Figures 1-6 There are multiple sliding seats 61, which are spaced apart along the length of the guide rail 62. Specifically, in this embodiment, there are two sliding seats 61, which slide and cooperate with the guide rail 62 simultaneously, further improving the guiding effect on the vertical movement of the CT scanner 1.

[0048] Furthermore, continue to refer to Figures 1-6The first telescopic component 31 includes a second linear drive source 311 and a first connector 312. The second linear drive source 311 is disposed on the fixed base 22. One end of the first connector 312 is connected to the output end of the second linear drive source 311, and the other end of the first connector 312 is connected to the second telescopic component 32. The second telescopic component 32 includes a third linear drive source 321 and a second connector 322. The third linear drive source 321 is connected to the first connector 312. One end of the second connector 322 is connected to the output end of the third linear drive source 321, and the other end of the second connector 322 is connected to the support rod 21. Specifically, the first connector 312 and the second connector 322 are configured as connecting rods, and the second linear drive source 311 and the third linear drive source 321 can be configured as servo electric cylinders. Under the driving action of the second linear drive source 311, the second telescopic component 32 is driven to move along the vertical height direction when the object being scanned is standing. At the same time, under the action of the third linear drive source 321, the CT scanner 1 can move away from or closer to the fixed frame along the vertical height direction of the object being scanned, thereby realizing the vertical scanning of the CT scanner 1. The multi-stage telescopic movement enables the CT scanner 1 to have a larger telescopic range along the vertical height direction.

[0049] Furthermore, continue to refer to Figures 1-6 The first telescopic component 31 also includes a guide seat, which is disposed on the second linear drive source 311. The second telescopic component 32 also includes a slide rail, which is disposed on the third linear drive source 321. The slide rail and the guide seat are slidably disposed. Specifically, the slide rail extends along the length direction of the third linear drive source 321 and is fixedly installed on one side of the third linear drive source 321. The guide seat is fixedly installed on one side of the second linear drive source 311. The guide seat is disposed on the slide rail and can slide along the slide rail, playing a certain guiding role and ensuring that the second telescopic component 32 moves along the vertical height direction when the scanned object is standing.

[0050] Preferably, adjacent universal adjustment components 41 are arranged in a V-shape or inverted V-shape, enabling the CT scanner 1 to perform six degrees of freedom of movement, covering the scanning needs of the whole body of the object being scanned, with high flexibility. Preferably, this vertical suspended CT scanning device uses advanced stability control algorithms and precision sensors to ensure the stability and accuracy of the equipment during the scanning process, improving image quality and the accuracy of the scanning results.
