Description

Technical Field

[0001] This application relates to the field of proton and heavy ion therapy devices, and particularly to a bracket for replacing a treatment couch. Background Art

[0002] It is known that a proton and heavy ion therapy device is a cutting-edge radiotherapy system based on a synchrocyclotron in the field of cancer treatment. During the treatment process, the patient usually lies on a treatment couch, and a beam is emitted by a rotating treatment head through 180 degrees or 360 degrees to accurately strike the tumor site of the patient. Therefore, the parameters of the treatment couch cannot be adjusted arbitrarily.

[0003] In the actual operation process, the treatment couch includes a robotic arm and a couch body installed on the robotic arm. However, the robotic arm is also extremely prone to failure or inaccurate movement during use. In addition, the actual situation is that there are very few hospitals in China that apply proton and heavy ion therapy devices. As a result, there are many treatment personnel, and the treatment plan needs to be carried out as scheduled. Or when the parameters of the therapy device need to be debugged and tested, since the treatment couch cannot be used, the patient's treatment plan is postponed, or the test cannot be carried out. Summary of the Invention

[0004] In order to improve the problems that testers cannot calibrate the test treatment couch in time, the maintenance time of the robotic arm is long, or the user is delayed in case of emergencies, this application provides a bracket for replacing a treatment couch.

[0005] A bracket for replacing a treatment couch provided by this application adopts the following technical solution: A bracket for replacing a treatment couch includes a couch board. Support platforms are respectively arranged at both ends of the couch board. A connecting plate is arranged above the support platforms. The connecting plate is located between the support platforms and the couch board. A bearing plate is arranged between the couch board and the connecting plate. A limiting frame is fixed on the support platform. The connecting plate slides in the limiting frame. A height coarse adjustment component is arranged between the support platform and the connecting plate. A height fine adjustment component is arranged between the connecting plate and the bearing plate. Horizontal adjustment mechanisms are arranged at both ends of the bearing plate.

[0006] By adopting the above technical solution, when the treatment couch fails, the tester cannot calibrate the test treatment couch in time, the maintenance time of the robotic arm is long, or the user is delayed in case of emergencies. At this time, the couch board is pushed into the treatment room so that the couch board is located under the treatment head, and the position of the couch board is adjusted according to the treatment needs to meet the treatment requirements. When the staff needs to adjust the height of the couch board, under the coordinated action of the height coarse adjustment component and the height fine adjustment component, the couch board is finally adjusted to an accurate position for subsequent treatment. After the height adjustment is completed, the horizontal position of the couch board is adjusted through the horizontal adjustment mechanism to ensure the smooth progress of the treatment.

[0007] Optionally, the height coarse adjustment assembly includes two fixed shells fixed on the support platform, worm wheels rotatably connected inside the fixed shells, worm shafts rotatably connected outside the fixed shells, and two first lead screws fixed on the side of the connecting plate facing away from the receiving plate. The two fixed shells are respectively located at both ends of the support platform, the two first lead screws are respectively located at both ends of the connecting plate, the two worm wheels are both meshed and connected to the worm shaft, the first lead screw is coaxially arranged with the worm wheel, and the first lead screw is threadedly connected to the worm wheel.

[0008] By adopting the above technical solution, when the worm shaft is rotated, the worm shaft drives the two worm wheels meshed with it to rotate synchronously. Since the first lead screw is coaxially arranged with the worm wheel and is threadedly connected, the rotation of the worm wheel will drive the first lead screw to move up and down along its own axis, thereby driving the connecting plate fixed on the first lead screw to slide within the limit frame, realizing the function of coarsely adjusting the height of the bed board.

[0009] Optionally, the height fine adjustment assembly includes two fine adjustment components, the two fine adjustment components are respectively located at both ends of the connecting plate, the fine adjustment component includes a fixed column fixed on the connecting plate, a second lead screw rotatably connected to the fixed column, a rotating disc coaxially fixed outside the second lead screw, and a first sleeve fixed on the side of the receiving plate facing away from the bed board. The second lead screw is threadedly connected to the first sleeve.

[0010] By adopting the above technical solution, when the rotating disc is rotated, the rotating disc drives the second lead screw coaxially arranged with it to rotate synchronously. Since the second lead screw is threadedly connected to the first sleeve fixed on the receiving plate, under the action of the thread, the rotational movement of the second lead screw is converted into a linear movement of the first sleeve, thereby realizing the fine adjustment function of the receiving plate fixed on the first sleeve in the vertical direction and realizing the function of finely adjusting the height of the bed board.

[0011] Optionally, the horizontal adjustment mechanism includes two groups of horizontal adjustment components, the two groups of horizontal adjustment components are symmetrically arranged on both sides of the bed board, the horizontal adjustment component includes a first fixed block fixed on the receiving plate, a first ejector rod threadedly connected to the first fixed block to move the bed board along the width direction of the receiving plate, a second fixed block fixed on the receiving plate, and a second ejector rod threadedly connected to the second fixed block to move the bed board along the length direction of the receiving plate. The first ejector rod and the second ejector rod are perpendicularly arranged.

[0012] By adopting the above technical solution, when it is necessary to adjust the position of the bed board in the width direction of the receiving board, only the first ejector rod needs to be rotated. Since the first ejector rod is threadedly connected to the first fixed block, rotating the first ejector rod can cause the first ejector rod to move along its own axis, thereby pushing the bed board to move in the width direction of the receiving board. When it is necessary to adjust the position of the bed board in the length direction of the receiving board, only the second ejector rod needs to be rotated. Since the second ejector rod is threadedly connected to the second fixed block, rotating the second ejector rod can cause the second ejector rod to move along its own axis, thereby driving the bed board to move in the length direction of the receiving board. Through the first ejector rod and the second ejector rod, the adjustment of the bed board in the horizontal position is jointly realized.

[0013] Optionally, a plurality of groups of adaptive structures are evenly spaced on the receiving board. The adaptive structure includes a receiving groove opened on the receiving board, a spring fixed in the receiving groove, a second sleeve vertically sliding in the receiving groove, a connecting rod fixed on the second sleeve, and an abutting block rotatably connected to the end of the connecting rod away from the spring. One end of the spring is fixed to the inner wall of the receiving groove, and the other end of the spring is fixed to the side wall of the second sleeve. The abutting block is a triangular block, and the edge of the abutting block is provided with an arc shape.

[0014] By adopting the above technical solution, when adjusting the fine-tuning component at one end of the bed board, since the other end of the bed board is not adjusted, there is a height difference between the two ends of the bed board, resulting in a gap between the bed board and the receiving board on the same side, and the receiving board cannot support the bed board well. When there is no height difference between the two ends of the bed board, the spring is in a compressed state at this time. When there is a height difference between the two ends of the bed board, the reset action of the spring will drive the second sleeve to slide in the receiving groove, thereby driving the connecting rod to move upward. Since the abutting block is rotatably connected to the connecting rod, the abutting block rotates in contact with the bed board and always maintains contact with the bed board. The adaptive structure can support the gap between the bed board and the receiving board, thereby effectively extending the service life of the bed board.

[0015] Optionally, a first reinforcing plate is fixed at the connection of the legs of the support platform, and a second reinforcing plate is fixed at the connection of the limiting frame and the support platform.

[0016] By adopting the above technical solution, the first reinforcing plate increases the stress area at the connection of the legs, avoiding damage to the connection part due to excessive stress. The second reinforcing plate increases the stress area at the connection of the limiting frame and the support platform, making the connection between the limiting frame and the support platform more firm.

[0017] In summary, the present application includes at least one of the following beneficial technical effects: 1. When the tester fails to calibrate the test treatment bed in time, the maintenance time of the robotic arm is long, or the user is delayed in case of emergencies, the fixed bracket is pushed into the treatment room, and the height and horizontal position of the bed board are adjusted to replace the treatment bed for subsequent treatment, with high usability.

[0018] 2. In actual use, first, the bed board is quickly adjusted to a rough height through the coarse height adjustment component, and then the bed board is adjusted to the precise height through the fine height adjustment component. Under the combined action of the coarse height adjustment component and the fine height adjustment component, the bed board is adjusted to the required height. Then, the horizontal position of the bed board is adjusted through the horizontal adjustment mechanism to meet the treatment requirements.

[0019] 3. When there is a height difference at both ends of the bed board, the bearing plate cannot support the bed board well. The spring drives the second sleeve to slide in the receiving groove, driving the connecting rod to move upward synchronously, and the abutting block rotates in contact with the bed board, and the abutting block always keeps in close contact with the bed board, so that the abutting block can support the bed board, thereby effectively extending the service life of the bed board.

Detailed implementation mode

[0023] The following will further describe the present application in detail with reference to the Figure 1-8 accompanying drawings.

[0024] An embodiment of the present application discloses a bracket for replacing a treatment bed.

[0025] Embodiment 1: Referring to Figure 1 , a bracket for replacing a treatment bed includes a bed board 1. The bed board 1 is made of carbon fiber, which is light in weight, extremely strong, and the carbon fiber material has good radiopacity performance and will not interfere with ray imaging.

[0026] Receiving plates 4 are arranged on both sides of the bed board 1. A connecting plate 3 is arranged between the receiving plate 4 and the support platform 2. A limiting frame 5 is fixed on the support platform 2, and the connecting plate 3 can slide within the limiting frame 5. Receiving plates 4 are arranged on both sides of the bed board 1.

[0027] Referring to Figure 1 and Figure 2 , a height coarse adjustment assembly 6 is arranged between the support platform 2 and the connecting plate 3. When the height of the bed board 1 needs to be adjusted, the bed board 1 is first quickly adjusted to a rough height by the height coarse adjustment assembly 6. The height coarse adjustment assembly 6 includes two fixed housings 601, two worm gears 602, a worm 603, and two first lead screws 604. Among them, the two fixed housings 601 are symmetrically fixed at both ends of the support platform 2, and the two first lead screws 604 are also symmetrically fixed at both ends of the connecting plate 3 respectively.

[0028] Referring to Figure 3, the worm gear 602 rotates inside the fixed housing 601, and the worm 603 is arranged outside the fixed housing 601. In this embodiment, the length of the worm 603 is greater than the length between the two worm gears 602, and both worm gears 602 are meshed and connected to both ends of the worm 603. The fixed housing 601 is sleeved at the meshing connection of the worm gear 602 and the worm 603, which can prevent the staff from accidentally touching the meshing connection of the worm gear 602 and the worm 603 and protect the staff from being injured.

[0029] The first lead screw 604 is coaxially arranged with the worm gear 602 inside the fixed housing 601, and the first lead screw 604 is threadedly connected to the worm gear 602, so that the rotational motion of the worm gear 602 can be converted into the vertical movement of the first lead screw 604.

[0030] Refer to Figure 3 , when the worm 603 rotates forward, the worm 603 drives the worm gear 602 to rotate. Since the first lead screw 604 is coaxially arranged with the worm gear 602 and threadedly connected, the rotation of the worm gear 602 will drive the first lead screw 604 to move upward along its own axis. Then, the first lead screw 604 drives the connecting plate 3 to slide upward in the limiting frame 5, realizing the rapid upward adjustment of the bed board 1. Similarly, when the worm 603 rotates reversely, the worm 603 drives the worm gear 602 to rotate, and the first lead screw 604 is coaxially arranged with the worm gear 602 and threadedly connected. The rotation of the worm gear 602 will drive the first lead screw 604 to move downward along its own axis. Then, the first lead screw 604 drives the connecting plate 3 to slide downward in the limiting frame 5, realizing the rapid downward adjustment of the bed board 1.

[0031] Refer to Figure 1 and Figure 4 , a height fine-tuning component 7 is arranged between the connecting plate 3 and the receiving plate 4. To adjust the height of the bed board 1, the height of the bed board 1 can be quickly adjusted to the approximate height by the height coarse-tuning component 6 first, and then adjusted to the precise height by the height fine-tuning component 7. The height fine-tuning component 7 includes two fine-tuning parts 71. The two fine-tuning parts 71 are symmetrically arranged at both ends of the connecting plate 3. The fine-tuning part 71 includes a fixed column 7101, a second lead screw 7102, a rotating disk 7103 and a first sleeve 7104.

[0032] Refer to Figure 4 , the fixed column 7101 is fixed on the side of the connecting plate 3 facing the receiving plate 4, the first sleeve 7104 is fixed on the side of the receiving plate 4 facing the connecting plate 3, the second lead screw 7102 rotates coaxially on the fixed column 7101, the rotating disk 7103 is coaxially fixed outside the second lead screw 7102, and the second lead screw 7102 is threadedly connected to the first sleeve 7104.

[0033] Refer to Figure 4, when the rotating disk 7103 is rotated clockwise, since the rotating disk 7103 and the second lead screw 7102 are fixed, the rotating disk 7103 drives the second lead screw 7102 to rotate clockwise synchronously. Under the action of the thread, the clockwise rotation of the second lead screw 7102 is converted into the upward linear motion of the first sleeve 7104, thereby realizing the fine-tuning function of the vertical upward movement of the bed board 1, so that the bed board 1 reaches the precise height. Similarly, when the rotating disk 7103 is rotated counterclockwise, the rotating disk 7103 drives the second lead screw 7102 to rotate counterclockwise synchronously. Under the action of the thread, the counterclockwise rotation of the second lead screw 7102 is converted into the downward linear motion of the first sleeve 7104, thereby realizing the fine-tuning function of the vertical downward movement of the bed board 1, so that the bed board 1 reaches the precise height.

[0034] Referring to Figure 1 and Figure 5 , a horizontal adjustment mechanism 8 is provided on the receiving plate 4. After the height of the bed board 1 is adjusted, sometimes it is also necessary to adjust the horizontal position of the bed board 1 to ensure the smooth progress of the treatment. The horizontal adjustment mechanism 8 includes two sets of horizontal adjustment components 81. The two sets of horizontal adjustment components 81 are symmetrically arranged on both sides of the bed board 1. The horizontal adjustment component 81 includes a first fixing block 8101, a first ejector rod 8102, a second fixing block 8103 and a second ejector rod 8104. The first ejector rod 8102 is perpendicular to the second ejector rod 8104.

[0035] The first fixing block 8101 is fixed on the side of the receiving plate 4 facing the bed board 1. The first ejector rod 8102 is threadedly connected to the first fixing block 8101, and rotating the first ejector rod 8102 can make the bed board 1 slide along the width direction of the receiving plate 4. The second fixing block 8103 is fixed on the side of the receiving plate 4 facing the bed board 1. The second ejector rod 8104 is threadedly connected to the second fixing block 8103, and rotating the second ejector rod 8104 can make the bed board 1 slide along the length direction of the receiving plate 4.

[0036] Referring to Figure 5 , when adjusting the position of the bed board 1 in the width direction of the receiving plate 4, only the first ejector rod 8102 needs to be rotated. Since the first ejector rod 8102 is threadedly connected to the first fixing block 8101, rotating the first ejector rod 8102 causes the first ejector rod 8102 to move axially, thereby pushing the bed board 1 to displace in the width direction. Similarly, when adjusting the position of the bed board 1 in the length direction of the receiving plate 4, only the second ejector rod 8104 needs to be rotated. Since the second ejector rod 8104 is threadedly connected to the second fixing block 8103, rotating the second ejector rod 8104 causes the second ejector rod 8104 to move axially, thereby driving the bed board 1 to move in the length direction. Under the combined action of the first ejector rod 8102 and the second ejector rod 8104, the horizontal position of the bed board 1 can be adjusted.

[0037] In the first embodiment of the present application, the implementation principle of a bracket for replacing a treatment bed is as follows: When the treatment bed fails, when the tester cannot calibrate the test treatment bed in time, the maintenance time of the robotic arm is long, or the user's use is delayed in case of emergencies, the bed board 1 is pushed into the treatment room at this time, so that the bed board 1 is located under the treatment head, and the position of the bed board 1 is adjusted according to the treatment needs to meet the treatment requirements. When the staff needs to adjust the height of the bed board 1, under the coordinated action of the height coarse adjustment component 6 and the height fine adjustment component 7, the bed board 1 is finally adjusted to an accurate position for subsequent treatment. After the height adjustment is completed, the horizontal position of the bed board 1 can also be adjusted through the horizontal adjustment mechanism 8 to meet the relevant treatment requirements, thereby ensuring the smooth progress of the treatment.

[0038] Embodiment 2: The difference between Embodiment 2 and Embodiment 1 is that with reference to Figure 6 and Figure 7 , a number of groups of adaptive structures 9 are evenly arranged at intervals on the receiving plate 4. The adaptive structure 9 includes a receiving groove 901, a spring 902, a second sleeve 903, a connecting rod 904, and an abutting block 905. Among them, the abutting block 905 is a triangular block, and the edge of the abutting block 905 is arranged in an arc shape, so that the abutting block 905 can fit the edge of the bed board 1 without damaging the bed board 1.

[0039] With reference to Figure 7 , the receiving groove 901 is opened on the receiving plate 4. The spring 902 is arranged between the receiving groove 901 and the second sleeve 903, and one end of the spring 902 is fixed to the inner wall of the receiving groove 901, and the other end of the spring 902 is fixed to the side wall of the second sleeve 903. The second sleeve 903 can slide on the receiving groove 901, the connecting rod 904 is fixed inside the second sleeve 903, and the abutting block 905 is rotatably connected to the connecting rod 904.

[0040] With reference to Figure 7 , in this embodiment, when the two ends of the bed board 1 are flush and there is no height difference, the spring 902 in the receiving groove 901 is in a compressed state at this time, and the abutting block 905 is located in the receiving groove 901 and fits the edge of the bed board 1. When there is a height difference between the two ends of the bed board 1, resulting in a gap between the bed board 1 and the receiving plate 4 on the same side, the reset action of the spring 902 drives the second sleeve 903 to slide in the receiving groove 901, and then drives the connecting rod 904 to move upward. In view of the fact that the abutting block 905 and the connecting rod 904 are rotatably connected, the abutting block 905 will fit and rotate with the bed board 1 and always keep in contact with the bed board 1. The adaptive structure 9 can support the gap between the bed board 1 and the receiving plate 4, effectively extending the service life of the bed board 1.

[0041] With reference to Figure 8, a first reinforcing plate 10 is fixed at the leg connection of the support table 2, and a second reinforcing plate 11 is fixed at the connection of the limit frame 5 and the support table 2. The first reinforcing plate 10 increases the thickness and stiffness of the connection, enabling the support table 2 to withstand greater external forces. Similarly, the second reinforcing plate 11 can ensure that the connection part between the limit frame 5 and the support table 2 will not be damaged due to the application of large external forces.
