Description

Technical Field

[0001] This application relates to the technical field of scanning instruments, and particularly to a mobile cone beam scanner system. Background Art

[0002] Since its application in clinical practice at the beginning of this century, cone beam CT has developed rapidly, and there are more detection methods for the sources of various pains. Currently, the main means of imaging examinations include magnetic resonance and CT scanners, and the application of cone beam scanners has also been effectively developed.

[0003] In related technical means, the scanner system includes an annular scanner and a detection bed, which can enable a human body to lie flat on the detection bed and scan the human body through the annular scanner. However, restricted by the support rod or support frame of the annular scanner, the scanner cannot pass through the entire detection bed, resulting in the need for the living body to adjust its position on the detection bed, and the comparison situation needs to be further improved. Summary of the Invention

[0004] In order to solve the problem that the existing scanner cannot pass through the entire detection bed, this application provides a mobile cone beam scanner system, adopting the following technical solutions:

[0005] A mobile cone beam scanner system includes a hollow scanner, a support base, and a detection bed. The scanner is suspended by a suspension device from the ceiling. The support base is located below the scanner. The detection bed is slidably connected to the support base. The detection bed can move horizontally relative to the scanner, and the suspension device can drive the scanner to move up and down in the vertical direction.

[0006] By adopting the above technical solutions, in this application, the scanner is suspended from the ceiling by the suspension device, so that there is no need to set a support rod or support frame below the scanner. Therefore, there is a larger space below the scanner to place the support base. By sliding the detection bed on the support base, the detection bed can move horizontally relative to the scanner, and the suspension device can drive the scanner to move up and down in the vertical direction. When a living body lies on the detection bed, only the height of the scanner needs to be controlled to enable the detection bed to pass through the scanner, and then the detection bed is controlled to slide on the support base, so that the part to be detected of the living body can be moved into the scanning area of the scanner, realizing the scanning of the living body.

[0007] Optionally, the scanner is rotatably connected to the suspension device through a rotating shaft. One end of the rotating shaft is provided with a driving motor, and the driving motor is fixed on the suspension device. The driving motor can drive the scanner to rotate and adjust the angle between the scanner and the ceiling or the top of the moving vehicle.

[0008] By adopting the above technical solution, the present application drives the scanner to rotate through the driving motor, adjusts the included angle between the scanner and the ceiling, so as to drive the scanner to rotate from the direction perpendicular to the ceiling or the top of the moving vehicle to the direction parallel to the ceiling or the top of the moving vehicle, reducing space occupation.

[0009] Optionally, the examination bed is provided with a geomagnetic sensor for detecting the inclination signal of the examination bed. The driving motor can receive the inclination signal detected by the geomagnetic sensor and drive the scanner to rotate so that the scanner remains perpendicular to the examination bed.

[0010] By adopting the above technical solution, the present application is provided with a geomagnetic sensor on the examination bed, so that the inclination of the examination bed or the support base can be detected, and then the scanner is driven by the driving motor to tilt, so that the scanner remains perpendicular to the examination bed, so that accurate scanning imaging can be performed when the examination bed is tilted, improving usability.

[0011] Optionally, the scanner includes a fixed ring and a scanner. The fixed ring is rotatably connected to the suspension device. The scanner is installed on the fixed ring and can move in a circular motion relative to the fixed ring. The interior of the scanner is hollow, and a metal detector is provided on the inner peripheral surface of the scanner.

[0012] By adopting the above technical solution, the metal detector can detect whether the living body on the examination bed carries metal objects or has metal objects in the body.

[0013] Optionally, the support base is provided with telescopic movable support feet. The movable support feet include a first cylinder and universal wheels. When the telescopic rod of the first cylinder shortens, the bottom of the universal wheels is higher than the bottom of the support base. When the telescopic rod of the first cylinder extends, the bottom of the universal wheels is lower than the bottom of the support base.

[0014] By adopting the above technical solution, the present application is provided with telescopic movable support feet on the support base. The movable support feet include a first cylinder and universal wheels. When not in need of movement, the telescopic rod of the first cylinder shortens, so that the support base supports on the ground, making the support base more stable and not easy to slide. When movement is needed, the telescopic rod of the first cylinder extends, so that the universal wheels support the support base, thus facilitating the movement of the support base.

[0015] Optionally, the support base is concave-shaped, and slideways are provided on both end support surfaces of the support base. A slide rail matching with the slideways is provided at the bottom of the examination bed. When both ends of the examination bed support on the both end support surfaces of the support base, an accommodation channel is formed between the examination bed and the support base, and the accommodation channel can allow the bottom of the scanner to pass through.

[0016] By adopting the above technical solution, the support base is arranged in a concave shape, and slideways are arranged on the two end support surfaces of the support base. When the two ends of the detection bed are supported on the two end support surfaces of the support base, an accommodation channel is formed between the detection bed and the support base, and the accommodation channel can allow the bottom of the scanner to pass through. Therefore, part of the scanner can be in the accommodation channel, saving space. On the other hand, when the detection bed slides left and right, at least one support surface can support the detection bed, and when the two support surfaces can support the detection bed simultaneously, the support stability can be improved.

[0017] Optionally, the support base is arranged in an L shape, and the detection bed is slidably connected to the support base through a lead screw module.

[0018] By adopting the above technical solution, the detection bed is slidably connected to the support base through a lead screw module, and the lead screw module is driven by a motor to drive the detection bed to move on the support base, so that automatic control can be carried out, and the detection bed can be limited at a preset position to prevent the detection bed from sliding during scanning.

[0019] Optionally, the suspension device includes a first support rod, a second support rod and a second cylinder. The first support rod is fixedly connected to the ceiling or the top of the mobile vehicle. One end of the second support rod is rotatably connected to the first support rod. The second cylinder is rotatably connected to the ceiling or the top of the mobile vehicle. The telescopic rod of the second cylinder is rotatably connected to the middle of the second support rod. The scanner is rotatably connected to the end of the second support rod away from the first support rod.

[0020] By adopting the above technical solution, in this application, the second cylinder drives the telescopic shaft to expand and contract, so that the second support rod drives the scanner to move up and down. When scanning is not performed, the scanner can be moved upward, and the scanner can be driven to rotate by a driving motor, thereby reducing the occupation of space. When scanning is required, the support base can be moved under the scanner, and then the scanner is controlled to move downward, and finally scanning is achieved.

[0021] Optionally, the suspension device includes a third support rod, a fourth support rod, a fifth support rod, and a third cylinder. One end of the third support rod is rotatably connected to the ceiling or the top of the mobile vehicle. The third cylinder is fixedly installed on the ceiling or the top of the mobile vehicle. The telescopic rod of the third cylinder is parallel to the ceiling or the top of the mobile vehicle. The third support rod is provided with a first sliding groove. The end of the telescopic rod of the third cylinder away from the third cylinder slides in the first sliding groove. The fourth support rod is rotatably connected to the end of the third support rod away from the ceiling or the top of the mobile vehicle. The scanner is rotatably connected to the end of the fourth support rod away from the third support rod. One end of the fifth support rod is rotatably connected to the ceiling or the top of the mobile vehicle, and the other end is rotatably connected to the end of the fourth support rod close to the scanner. The fifth support rod is arranged parallel to the third support rod.

[0022] By adopting the above technical solution, when the third cylinder drives the telescopic rod of the third cylinder to extend, the third support rod gradually becomes parallel to the ceiling or the top of the mobile vehicle, driving the fourth support rod to rise, thereby driving the scanner to rise. And the scanner can be driven to rotate by the driving motor, so as to realize storing the scanner on the ceiling or the top of the mobile vehicle, reducing the occupation of space.

[0023] Optionally, the suspension device includes a sixth support rod, a seventh support rod, a fourth cylinder, and a fifth cylinder. One end of the sixth support rod is rotatably connected to the ceiling or the top of the mobile vehicle. The fourth cylinder is fixedly installed on the ceiling or the top of the mobile vehicle. The telescopic rod of the fourth cylinder is parallel to the ceiling or the top of the mobile vehicle. The sixth support rod is provided with a second sliding groove. The end of the telescopic rod of the fourth cylinder away from the fourth cylinder slides in the second sliding groove. One end of the seventh support rod is rotatably connected to the ceiling or the top of the mobile vehicle, and the other end is rotatably connected to the end of the sixth support rod close to the scanner. One end of the fifth cylinder is rotatably connected to the ceiling or the top of the mobile vehicle, and the other end is rotatably connected to the seventh support rod.

[0024] By adopting the above technical solution, when the fourth cylinder drives the telescopic rod of the fourth cylinder to extend, the sixth support rod gradually becomes parallel to the ceiling or the top of the mobile vehicle, driving the seventh telescopic rod to rise, thereby driving the scanner to rise. At the same time, when the fifth cylinder drives the telescopic rod of the fifth cylinder to shorten, it further drives the scanner to rise. And the scanner can be driven to rotate by the driving motor, so as to realize storing the scanner on the ceiling or the top of the mobile vehicle, reducing the occupation of space.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. In this application, the scanner ceiling is set through a suspension device, so that there is no need to set a support rod or support frame below the scanner. Therefore, there is a larger space below the scanner to place the support base. By sliding the examination bed on the support base, the examination bed can move horizontally relative to the scanner, and the suspension device can drive the scanner to move up and down in the vertical direction. When a living body lies on the examination bed, only the height of the scanner needs to be controlled so that the examination bed can pass through the scanner, and then the examination bed is controlled to slide on the support base, so that the part to be detected of the living body can be moved into the scanning area of the scanner, realizing the scanning of the living body;

[0027] 2. In this application, a geomagnetic sensor is set on the examination bed or the support base, so that the inclination of the examination bed or the support base can be detected, and then the scanner is driven to tilt by a driving motor, so that the scanner is kept perpendicular to the examination bed, so that accurate scanning imaging can be carried out when the examination bed is tilted, improving usability;

[0028] 3. In this application, a telescopic moving support foot is set on the support base. The moving support foot includes a first cylinder and a universal wheel.

[0038] Embodiment 1

[0039] An embodiment of the present application discloses a movable cone-beam scanner system. Referring to Figure 1 and Figure 2 , the movable cone-beam scanner system includes a hollow scanner 100, a support base 200, and a detection bed 300. The scanner 100 is suspended from the ceiling through a suspension device 400. The support base 200 is located below the scanner 100. The detection bed 300 is slidably connected to the support base 200, so that the detection bed 300 can move horizontally relative to the scanner 100, and the suspension device 400 can drive the scanner 100 to move up and down in the vertical direction.

[0040] Among them, the scanner 100 of the present application is in a ring shape. The scanner 100 includes a fixed ring 110 and a scanner 120. The fixed ring 110 is rotatably connected to the suspension device 400. The scanner 120 is installed on the fixed ring 110 and can move circumferentially relative to the fixed ring 110. The interior of the scanner 120 is hollow, and a metal detector (not shown in the figure) is provided on the inner peripheral surface of the scanner 120. When used indoors, it can be suspended on the ceiling through the suspension device 400. When used on a mobile vehicle such as an ambulance, it can be suspended on the top of the vehicle. Since there is no need to provide a support rod or support frame below the scanner 100, there is a larger space below the scanner 100 to place the support base 200, enabling the examination bed 300 to pass through the fixed ring 110, allowing the scanner 120 to scan the living body on the examination bed 300, and enabling the examination bed 300 to slide within the scanner 100, so that the scanner 100 can pass through the entire examination bed 300.

[0041] When the movable cone-beam scanner system of the present application is used in a small space or a mobile vehicle such as an ambulance, in order to reduce the space occupied by the scanner 100 and adjust the angle of the scanner 100. The scanner 100 of the present application is rotatably connected to the suspension device 400 through a rotating shaft 500. One end of the rotating shaft 500 is provided with a driving motor 600. The driving motor 600 is fixed on the suspension device 400 to drive the rotating shaft 500 to rotate and drive the scanner 100 to rotate from a direction perpendicular to the ceiling or the top of the mobile vehicle to a direction parallel to the ceiling or the top of the mobile vehicle, reducing the space occupied.

[0042] Specifically, in this embodiment, the suspension device 400 includes a first support rod 411, a second support rod 412, and a second cylinder 413. The first support rod 411 is fixedly connected to the ceiling or the top of the mobile vehicle. One end of the second support rod 412 is rotatably connected to the first support rod 411. The second cylinder 413 is rotatably connected to the ceiling or the top of the mobile vehicle. The telescopic rod of the second cylinder is rotatably connected to the middle of the second support rod 412. The scanner 100 is rotatably connected to the end of the second support rod 412 away from the first support rod 411. When scanning is not required, the second cylinder 413 drives the telescopic rod of the second cylinder to shorten, and the second support rod 412 and the scanner 100 move upward, thereby further reducing the space occupied. When scanning is required, the support base 200 is moved below the scanner 100, and then the scanner 100 is controlled to move downward, and finally scanning is achieved.

[0043] Specifically, the support base 200 is arranged in a concave shape. Slideways 220 are arranged on both end support surfaces of the support base 200. A slide rail 310 matching with the slideways 220 is arranged at the bottom of the detection bed 300. When both ends of the detection bed 300 are supported on the two end support surfaces of the support base 200, a receiving channel 700 is formed between the detection bed 300 and the support base 200, and the receiving channel 700 can allow the bottom of the scanner 100 to pass through. When the detection bed 300 slides left and right, at least one support surface can support the detection bed 300, and when both support surfaces can support the detection bed 300 simultaneously, the support stability can be improved.

[0044] In some embodiments, as Figure 3 shown, the support base 200 is arranged in an L shape, which is convenient for the detection bed 300 to pass through the scanner 100. The detection bed 300 can be slidably connected to the support base 200 through a lead screw module, so as to realize automatic control, and can control the detection bed 300 to be positioned at a preset position to prevent the detection bed 300 from sliding during scanning. Further, a base 230 can be arranged at the bottom of the support base 200, and the cross section of the base 230 is larger than the cross section of the bottom of the support base 200 to increase the placement stability.

[0045] When the support base 200 is arranged in an L shape, when the detection bed 300 moves to one end of the support base 200, since only one end of the detection bed 300 has support, the end of the detection bed 300 far from the support base 200 may tilt under the action of gravity. In order to keep the scanner 100 perpendicular to the detection bed 300 for more accurate scanning and imaging, the detection bed 300 is provided with a geomagnetic sensor (not shown in the figure). The geomagnetic sensor is used to detect the tilt degree of the detection bed 300. The drive motor 600 can receive the tilt degree signal detected by the geomagnetic sensor and drive the scanner 100 to rotate so that the scanner 100 is kept perpendicular to the detection bed 300.

[0046] In some application scenarios such as ambulances, when the scanner 100 is working, the support base 200 needs to be kept stable. When the ambulance arrives at the hospital, the living body needs to be quickly moved to the hospital.

[0047] Therefore, as Figure 2As shown in the figure, in the embodiment of the present application, the support base 200 is provided with a telescopic moving support foot 210. The moving support foot 210 includes a first air cylinder 211 and a universal wheel 212. When the telescopic rod of the first air cylinder shortens, the bottom of the universal wheel 212 is higher than the bottom of the support base 200, so that the bottom of the support base 200 can support on the ambulance. The support base 200 has a larger contact surface with the ambulance, avoiding the movement of the support base 200 caused by the bump of the ambulance. When the telescopic rod of the first air cylinder extends, the bottom of the universal wheel 212 is lower than the bottom of the support base 200, so that the support base 200 can be quickly pushed when the ambulance arrives at the hospital, so as to treat the living body.

[0048] Optionally, straps or the like can be provided on the support base 200 to further fix the living body.

[0049] Embodiment Two

[0050] Refer to Figure 4 , Figure 4 which is another schematic diagram of the suspension device in the embodiment of the present application.

[0051] Embodiment Two of the present application gives another possible structural diagram of the suspension device. The difference from Embodiment One is that the suspension device 400 includes a third support rod 421, a fourth support rod 422, a fifth support rod 423 and a third air cylinder 424. One end of the third support rod 421 is rotatably connected to the ceiling or the top of the mobile vehicle. The third air cylinder 424 is fixedly installed on the ceiling or the top of the mobile vehicle. The telescopic rod of the third air cylinder is parallel to the ceiling or the top of the mobile vehicle. The third support rod 421 is provided with a first sliding groove (not shown in the figure). One end of the telescopic rod of the third air cylinder away from the third air cylinder 424 slides in the first sliding groove. The fourth support rod 422 is rotatably connected to the end of the third support rod away from the ceiling or the top of the mobile vehicle. The scanner 100 is rotatably connected to the end of the fourth support rod 422 away from the third support rod 421. One end of the fifth support rod 423 is rotatably connected to the ceiling or the top of the mobile vehicle, and the other end is rotatably connected to the end of the fourth support rod 422 close to the scanner 100. The fifth support rod 423 is arranged parallel to the third support rod 421. When the third air cylinder 424 drives the telescopic rod of the third air cylinder to extend, the third support rod 421 gradually becomes parallel to the ceiling or the top of the mobile vehicle, driving the fourth support rod 422 to rise, thereby driving the scanner 100 to rise. And the scanner 100 can be driven to rotate by the driving motor 600, so as to realize the storage of the scanner 100 on the ceiling or the top of the mobile vehicle, reducing the occupation of space.

[0052] Embodiment Three

[0053] Refer to Figure 5 and Figure 6 , Figure 5 which is another schematic diagram of the suspension device in the embodiment of the present application.

[0054] Embodiment 3 of the present application provides another possible structural diagram of the suspension device. The difference from Embodiment 1 is that the suspension device 400 includes a sixth support rod 431, a seventh support rod 432, a fourth cylinder 433, and a fifth cylinder 434. One end of the sixth support rod 431 is rotatably connected to the ceiling or the top of the mobile vehicle. The fourth cylinder 433 is fixedly installed on the ceiling or the top of the mobile vehicle. The telescopic rod of the fourth cylinder is parallel to the ceiling or the top of the mobile vehicle. The sixth support rod 431 is provided with a second sliding groove (not shown in the figure). One end of the telescopic rod of the fourth cylinder away from the fourth cylinder 433 slides in the second sliding groove. One end of the seventh support rod 432 is rotatably connected to the ceiling or the top of the mobile vehicle, and the other end is rotatably connected to one end of the sixth support rod 431 close to the scanner 100. One end of the fifth cylinder 434 is rotatably connected to the ceiling or the top of the mobile vehicle, and the other end is rotatably connected to the seventh support rod 432. When the fourth cylinder 433 drives the telescopic rod of the fourth cylinder to extend, the sixth support rod 431 gradually becomes parallel to the ceiling or the top of the mobile vehicle, driving the seventh telescopic rod to rise, thereby driving the scanner 100 to rise. At the same time, when the fifth cylinder 434 drives the telescopic rod of the fifth cylinder to shorten, it further drives the scanner 100 to rise. And the driving motor 600 can drive the scanner 100 to rotate, so as to realize the storage of the scanner 100 on the ceiling or the top of the mobile vehicle, reducing the occupation of space.

[0055] The implementation principle of the movable cone-beam scanner system in an embodiment of the present application is as follows: The present application suspends the scanner 100 from the ceiling through the suspension device 400, so that there is no need to set a support rod or a support frame below the scanner 100. Therefore, there is a larger space below the scanner 100 to place the support base 200. By making the detection bed 300 slide on the support base 200, the detection bed 300 can move horizontally relative to the scanner 100. The suspension device 400 can drive the scanner 100 to move up and down in the vertical direction. When a living body lies on the detection bed 300, only the height of the scanner 100 needs to be controlled so that the detection bed 300 can pass through the scanner 100, and then by controlling the detection bed 300 to slide on the support base 200, the part to be detected of the living body can be moved into the scanning area of the scanner 100, realizing the scanning of the living body.

[0056] The above are all the preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
