Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device technology, and in particular to core mounting fixtures, core mounting methods, accelerators, and radiotherapy equipment. Background Technology
[0002] Radiation therapy is one of the three main methods of cancer treatment. Radiation therapy primarily utilizes linear accelerators, proton accelerators, and carbon ion accelerators. Among these, a proton accelerator is a radiation therapy system that provides proton beams for clinical treatment. It delivers a proton beam with a prescribed dose and three-dimensional dose distribution, provided by a treatment planning system, to the designated treatment site on the patient.
[0003] The accelerator is the core component of this radiotherapy system, consisting of the accelerator body and the core. The core, located within the accelerator body, is a crucial part of it. During testing, the accelerator needs to be frequently opened and the core removed for the installation of testing instruments and the adjustment of internal parts.
[0004] After the accelerator testing is completed, the core needs to be assembled into the accelerator body. This requires transferring the core during opening or assembly. Currently, there is no specialized transfer fixture, making it impossible to accurately move the core into or out of the accelerator body.
[0005] Therefore, there is an urgent need for core installation fixtures, core installation methods, accelerators, and radiotherapy equipment to solve the above problems. Summary of the Invention

The guide member is used to guide the front-back movement of the frame so that the core is aligned with the core mounting position on the accelerator body, thereby assembling the core into or removing it from the core mounting position.
[0011] A buffer is disposed on the side of the frame facing the accelerator body, the accelerator body is disposed on the accelerator support, the buffer is configured to abut against the accelerator support before the core moves to the core mounting position, and the buffer can retract in a direction away from the accelerator support to buffer the core.
[0012] As an optional solution, the guide component includes a guide wheel and a guide fixing plate. The guide fixing plate is disposed at the top of the frame, and the guide wheel is rotatably disposed on the guide fixing plate. The guide wheel is used to rotate in the horizontal plane, and the outer peripheral surface of the guide wheel is used to abut against the inner side of the guide plate vertically disposed on the accelerator bracket and roll forward or backward, thereby causing the frame to move back and forth along the extension direction of the guide plate.
[0013] As an optional solution, the adapter is an adapter plate, and the adapter plate and the core are provided with multiple pin holes facing each other. The adapter includes a positioning pin, which is used to pass through the pin holes on the adapter plate and the core in sequence.

[0016] Two sets of position adjustment components are disposed on the frame. The position adjustment components can drive the adapter to move in a direction parallel to the mounting surface of the frame, and the driving directions of the two sets of position adjustment components on the adapter are perpendicular to each other.
[0017] As an optional solution, each set of position adjustment components includes two adjusting bolts and at least one adjusting fixing block. The adjusting bolts are threadedly connected to the adjusting fixing block, with one end of the adjusting bolt extending out of the adjusting fixing block and facing the adapter. The adjusting bolts are used to be screwed to move against the adapter, thereby adjusting the position of the adapter in the up-down or left-right direction.
[0018] As an optional solution, the tooling assembly further includes:
[0019] An angle adjustment component is provided on the frame, and the angle adjustment component is configured to adjust the angle between the adapter and the mounting surface.
[0020] As an optional solution, the tilt adjustment component includes a plurality of tilt adjustment bolts, which are spaced apart on the frame. The tilt adjustment bolts are used to extend out of the mounting surface and abut against the adapter in the front-to-back direction. The tilt adjustment bolts are configured to be screwed to adjust the length of the tilt adjustment bolts extending out of the mounting surface.
[0021] As an optional solution, the rollers include a front roller near the front end of the frame and a rear roller near the rear end of the frame, and a counterweight block is provided at the rear end of the frame near the rear roller.
[0022] As an optional solution, the tooling assembly further includes:
[0023] A third fastener is disposed on the side of the frame facing the accelerator body, and the third fastener is used to connect the frame and the accelerator support.
[0024] Another objective of this invention is to provide a core mounting method, which uses the aforementioned core mounting fixture to assemble the core, thereby improving assembly convenience and accuracy.
[0025] To achieve this objective, the present invention adopts the following technical solution:
[0026] The core mounting method, using the core mounting fixture described above, includes the following steps:
[0027] The core is positioned and installed on the adapter;

[0029] Move the frame so that it approaches the accelerator body mounted on the accelerator bracket in the direction indicated by the guide, align the core with the core mounting position on the accelerator body, stop moving when the core reaches the core mounting position, assemble the core into the core mounting position, release the fixation between the core and the adapter, and remove the core mounting fixture.
[0030] As an optional solution, during the process of the frame approaching the accelerator body, when the buffer abuts against the accelerator support, the frame temporarily stops moving, the buffer retracts away from the accelerator support, and after the buffer avoids the accelerator support, it continues to push the frame so that the core enters the core mounting position.
[0031] Another object of the present invention is to provide an accelerator that uses the above-described core mounting fixture for core assembly and disassembly, thereby improving operational convenience.
[0032] To achieve this objective, the present invention adopts the following technical solution:
[0033] An accelerator includes an accelerator body and a core. The accelerator body has a core mounting position, and the core is assembled in the core mounting position. The core is moved into or out of the accelerator body by a core mounting fixture as described above. The core is connected to the accelerator body by a plurality of fourth fasteners. The core is configured to be connected to the adapter.
[0034] As an optional solution, the accelerator body is mounted on an accelerator bracket, and a guide plate is provided on the side of the accelerator bracket facing the core mounting fixture to guide the guide member to move in the front-back direction.
[0035] Another object of the present invention is to provide a radiotherapy device that can be easily disassembled and assembled.
[0036] To achieve this objective, the present invention adopts the following technical solution:
[0037] Radiation therapy equipment, including the accelerator described above.
[0038] Beneficial effects:
[0039] The core mounting fixture proposed in this invention, when requiring core installation, first positions the core on the adapter, then installs the adapter with the core on it onto the frame. Next, the frame is moved closer to the accelerator body according to the direction indicated by the guide, aligning the core with the core mounting position on the accelerator body. When the core reaches the mounting position, the frame stops moving, and the core is assembled into the mounting position. The frame with rollers allows for easy transfer of the core, and the guide ensures precise installation of the core onto the accelerator body. When the core needs to be removed from the accelerator body, the adapter is first connected to the core, then the frame is moved towards the accelerator body. Guided by the guide, the frame and adapter are aligned, the adapter is connected to the frame, and then the frame is moved to remove the core from the accelerator body. By incorporating a buffer, damage to both the core and the accelerator body can be prevented from directly colliding during the core's movement.
[0040] The core mounting method proposed in this invention improves the convenience and accuracy of core assembly by using the aforementioned core mounting fixture.
[0041] The accelerator proposed in this invention improves operational convenience by using the aforementioned core mounting fixture for core assembly and disassembly.
[0042] The radiotherapy device proposed in this invention, by adopting the aforementioned core installation fixture, enables safer and more convenient disassembly and assembly of the core, avoids accidental collisions between the core and objects outside the core installation position, improves production and testing efficiency, greatly reduces product manufacturing and testing costs, and enhances the competitiveness of the radiotherapy device.

[0052] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0056] Accelerators are the core components of radiotherapy systems, such as... Figure 1 As shown, the accelerator includes an accelerator body 200 and a core 100. The accelerator body 200 is mounted on an accelerator support 300, which provides fixed support for the accelerator body 200. The core 100, also known as a plug, is located within the accelerator body 200. Figure 1 The image shows the core 100 being removed from the accelerator body 200; the core 100 is an important component of the accelerator. (Combined) Figure 1 and Figure 2 The core 100 is connected to the accelerator body 200 via multiple fourth fasteners 110. During testing, the accelerator needs to be frequently opened to remove the core 100 for instrument installation and internal component adjustments. The fourth fasteners 110 are typically bolts or screws.
[0057] To facilitate the transfer and installation of the core 100, such as Figure 1 and Figure 2 As shown, this embodiment provides a core mounting fixture, which includes an adapter 1 and a fixture frame assembly 2. The adapter 1 is used to position and mount the core 100. The fixture frame assembly 2 includes a frame 21 for positioning and mounting the adapter 1 and a guide 22 disposed on the frame 21. The bottom side of the frame 21 is provided with multiple rollers 23 to enable the frame 21 to move in the front-back direction. The guide 22 is disposed at the top of the frame 21 to guide the movement of the frame 21 in the front-back direction, so that the core 100 moves to align with the core mounting position 210 on the accelerator body 200, thereby assembling the core 100 into or removing it from the core mounting position 210.
[0058] The tooling frame assembly 2 also includes a buffer 26, which is disposed on the side of the frame 21 facing the accelerator body 200. The accelerator body 200 is disposed on the accelerator support 300. The buffer 26 is configured to abut against the accelerator support 300 before the core 100 moves to the core mounting position 210, and the buffer 26 can retract in a direction away from the accelerator support 300 to buffer the core 100.
[0059] When the core 100 needs to be installed, first position the core 100 on the adapter 1, then install the adapter 1 with the core 100 on it onto the frame 21. Next, move the frame 21 so that it approaches the accelerator body 200 in the direction indicated by the guide 22 (front-back direction), aligning the core 100 with the core mounting position 210 on the accelerator body 200. When the core 100 reaches the core mounting position 210, the frame 21 stops moving, and the core 100 is installed in the core mounting position 210. The frame 21 with rollers 23 allows for easy transfer of the core 100, and the guide 22 allows the core 100 to be aligned with the core mounting position 210 on the accelerator body 200, enabling quick and precise installation of the core 100 onto the accelerator body 200.
[0060] After the buffer 26 abuts against the accelerator support 300, it retracts away from the accelerator support 300, thus avoiding it. At this point, the core 100 is very close to the accelerator body 200. The frame 21 is then slowly pushed forward, allowing the core 100 to enter the core mounting position 210 at a low speed, which helps prevent the core 100 from colliding with the accelerator body 200. By setting the buffer 26 to abut against the accelerator support 300 first, damage to both the core 100 and the accelerator body 200 is prevented from occurring during movement. Preferably, two buffers 26 are provided, one on the left and one on the right side of the frame 21, to provide a relatively uniform buffering force and prevent uneven force on the frame 21, which could cause it to tilt.
[0061] When it is necessary to remove the core 100 from the accelerator body 200, first connect the adapter 1 to the core 100, then move the frame 21 toward the accelerator body 200. Guided by the aforementioned guide 22, the frame 21 and the adapter 1 can be connected. Connect the adapter 1 to the frame 21, and then move the frame 21 to move the core 100 out of the accelerator body 200. The operation is relatively convenient.
[0062] Optionally, such as Figure 3 As shown, the adapter 1 is an adapter plate. Multiple pin holes are arranged opposite each other on the adapter plate and the core 100. The adapter 1 includes positioning pins 11, which are used to pass sequentially through the pin holes on the adapter plate and the core 100. In this embodiment, two positioning pins 11 are provided, with the two pin holes on the adapter plate spaced apart. This allows for positioning of the adapter 1, preventing it from rotating freely relative to the core 100, thus fixing the adapter 1 and the core 100 in a specific relative position. Of course, three or more positioning pins 11 can also be provided; the number of positioning pins 11 is not limited here.
[0063] Furthermore, such as Figure 3 As shown, the adapter 1 is provided with a plurality of first fasteners 12, which are used to connect the core 100 and the adapter 1. The first fasteners 12 can be bolts or screws. After the core 100 and the adapter 1 are fixed in relative position by the positioning pins 11, the core 100 and the adapter 1 are connected into a whole by the first fasteners 12. Afterwards, the positioning pins 11 can be removed to facilitate the subsequent connection of the adapter 1 and the frame 21.
[0064] Optionally, such as Figure 3 As shown, the adapter 1 is octagonal with a circular hole in the center. The positioning pin 11 and the first fastener 12 are arranged around the circular hole. By setting the circular hole, the weight of the adapter 1 is reduced, which helps to reduce the load on the frame 21.
[0065] Further, please return to the reference. Figure 2The frame 21 includes a horizontal frame 211, a vertical frame 212, and a support frame 213. The horizontal frame 211 is rectangular, and each of its four corners is equipped with a roller 23, arranged to form a front roller near the bottom of the vertical frame 212 and a rear roller near the bottom of the support frame 213. The rollers 23 can be casters for easy movement. Locking devices can also be provided for the rollers 23 to lock them in place after the frame 21 is in position. The vertical frame 212 is located at the front end of the horizontal frame 211 and is perpendicular to it. An adapter 1 can be connected to the vertical frame 212. The frame 21 moves forward to insert the core 100 into the accelerator body 200. The support frame 213 is inclined and connects the horizontal frame 211 and the vertical frame 212, improving the structural strength of the vertical frame 212.
[0066] Optionally, such as Figure 2 As shown, the frame 21 also includes a mounting plate 214, which is located on the front side of the vertical frame 212. The adapter 1 can be connected to the mounting plate 214. Since the adapter 1 is octagonal, the mounting plate 214 is also octagonal. The upper and lower sides of the mounting plate 214 are horizontally arranged, and the upper and lower sides of the adapter 1 are also horizontally arranged. The vertical length of the mounting plate 214 is less than that of the adapter 1, and the horizontal length of the mounting plate 214 is greater than that of the adapter 1. That is, the upper end of the adapter 1 extends above the mounting plate 214. A lifting hole 14 is provided at the upper end of the adapter 1, and a center hole 120 is provided at the front end of the core 100. The center hole 120 is used for lifting the core 100. The assembly formed by the adapter 1 and the core 100 can be transferred to the mounting plate 214 by lifting. When lifting the assembly of the adapter 1 and the core 100, the center hole 120 and the lifting hole 14 are connected to maintain balance. The design of the upper end of the adapter 1 extending above the mounting plate 214 ensures that the mounting plate 214 avoids the lifting hole 14, preventing interference between the lifting equipment and the mounting plate 214. Since the mounting plate 214 does not need to be disassembled, it can be welded to the vertical frame 212, which is convenient and provides a relatively strong connection. Of course, bolted connections can also be used; this is not a limitation.
[0067] like Figure 2 As shown, the vertical frame 212 is located at the front end of the horizontal frame 211. The weight of the adapter 1 and the core 100 is mainly concentrated at the front end of the horizontal frame 211. To maintain the balance of the frame 21, a counterweight 28 is provided at the rear end of the horizontal frame 211 near the rear roller. The counterweight 28 can be configured as a multi-layered split structure, and the multi-layered counterweight 28 can be detachably connected to the horizontal frame 211 by bolts. In actual operation, the actual number of counterweights 28 required can be determined according to the weight of the core 100 to be moved laterally.
[0068] Furthermore, such as Figure 4As shown, the adapter 1 and the frame 21 are connected by multiple second fasteners 13, that is, the adapter 1 and the mounting plate 214 are connected by multiple second fasteners 13. The second fasteners 13 can be bolts. In this embodiment, four second fasteners 13 are provided. Of course, more or fewer than four second fasteners 13 can be provided, as long as they can achieve a fastening connection between the adapter 1 and the mounting plate 214.
[0069] Optionally, the connecting hole 2141 on the mounting plate 214 through which the second fastener 13 passes is set as an oblong hole with the length of the oblong hole extending vertically. The second fastener 13 can move within the oblong hole to finely adjust the position of the adapter 1 relative to the mounting plate 214, so as to ensure that the position of the core 100 on the adapter 1 is relatively accurate.
[0070] Furthermore, such as Figure 2 As shown, the tooling frame assembly 2 also includes two sets of position adjustment components 24. The position adjustment components 24 are mounted on the frame 21, which has a mounting surface for cooperating with the adapter 1. The position adjustment components 24 can drive the adapter 1 to move along the mounting surface parallel to the frame 21. The driving directions of the two sets of position adjustment components 24 relative to the adapter 1 are perpendicular, meaning the position adjustment components 24 can drive the adapter 1 to move left and right and up and down, adjusting the position of the adapter 1 on the mounting plate 214. By driving the adapter 1 to move in two perpendicular directions through the position adjustment components 24, the position of the adapter 1 on the mounting plate 214 is adjusted, ensuring that when the frame 21 moves under the guidance of the guide component 22, the core 100 is aligned with the accelerator body 200, thus ensuring that the core 100 is smoothly installed in the core mounting position 210. Adjusting the two sets of position adjustment components 24 allows for rotation of the adapter 1 at a certain angle on a vertical plane, which is perpendicular to the ground.
[0071] Specifically, such as Figure 2 As shown, a set of position adjustment components 24 is disposed on the mounting plate 214, located on the left side of the adapter 1. This set of position adjustment components 24 is used to adjust the left and right position of the adapter 1 relative to the mounting plate 214. Of course, in other embodiments, this set of position adjustment components 24 can also be disposed on the right side of the adapter 1, which can also achieve the adjustment of the left and right position of the adapter 1. Another set of position adjustment components 24 is located on the lower side of the adapter 1, disposed on the vertical frame 212. This set of position adjustment components 24 is used to adjust the up and down position of the adapter 1 relative to the mounting plate 214.
[0072] Optionally, each set of position adjusting components 24 includes two adjusting bolts 241 and at least one adjusting fixing block 242, with the adjusting bolts 241 threadedly connected to the adjusting fixing block 242. One end of the adjusting bolt 241 extends out of the adjusting fixing block 242 and faces the adapter 1. The adjusting bolt 241 is used to be turned to move against the adapter 1, thereby adjusting the position of the adapter 1 in the up-down or left-right direction.
[0073] Furthermore, the tooling frame assembly 2 also includes a tilt adjustment component, which is disposed on the frame 21, specifically on the mounting plate 214. The tilt adjustment component is used to adjust the angle between the adapter 1 and the mounting surface, so as to further align the core 100 with the accelerator body 200. The mounting surface refers to the front side of the mounting plate 214 of the frame 21.
[0074] Specifically, in combination Figure 1 and Figure 4 The tilt adjustment component includes multiple tilt adjustment bolts 25, which are spaced apart on the mounting plate 214. Each tilt adjustment bolt 25 extends beyond the mounting surface and abuts against the adapter 1 in the front-to-back direction. The bolts 25 are designed to be screwed to adjust their length extending beyond the mounting surface. Tightening the bolts 25 adjusts their length extending beyond the mounting surface, thereby adjusting the distance between the adapter 1 and the mounting plate 214. This difference in the length of each bolt extending beyond the mounting surface allows for adjustment of the tilt angle of the adapter 1 relative to the mounting plate 214. In this embodiment, five tilt adjustment bolts 25 are provided, two at the lower end of the mounting plate 214, and the other three at the upper, left, and right ends, respectively. However, the number of tilt adjustment bolts 25 is not limited to five, nor are their positions restricted, as long as the tilt angle of the adapter 1 relative to the mounting plate 214 can be adjusted.
[0075] Optionally, such as Figure 2 As shown, the tooling frame assembly 2 also includes a third fastener 27, which is disposed on the side of the frame 21 facing the accelerator body 200. The third fastener 27 is used to connect the frame 21 and the accelerator support 300. The third fastener 27 may be a bolt.
[0076] The tooling assembly 2 moves forward, gradually bringing the core 100 closer to the accelerator body 200. Once the core 100 is fully inside the core mounting position 210, the frame 21 and the accelerator support 300 are connected and secured using the third fastener 27. The core 100 is then connected to the accelerator body 200. After the core 100 is assembled, the first fastener 12 is turned to disconnect the core 100 from the adapter 1, allowing them to separate. Then, the third fastener 27 is turned to disconnect the frame 21 from the accelerator support 300, and the tooling assembly 2 is pushed backward away from the accelerator.
[0077] Optionally, such as Figure 4 As shown, the mounting plate 214 is provided with a plurality of first clearance holes 2142. The first fastener 12 is provided in a one-to-one correspondence with the first clearance holes 2142. The first clearance holes 2142 provide clearance space for the first fastener 12, and at the same time, the first fastener 12 can be screwed from the rear side of the mounting plate 214 to disconnect the core 100 and the adapter 1.
[0078] The mounting plate 214 and the adapter 1 are provided with multiple second clearance holes 2143 facing each other. The fourth fastener 110 is provided with a one-to-one correspondence with the second clearance holes 2143. The second clearance holes 2143 provide clearance space for the fourth fastener 110. At the same time, the second fastener 13 can be screwed from the rear side of the mounting plate 214 so that the core 100 and the accelerator body 200 can be connected or disconnected when the core 100, the adapter 1 and the mounting plate 214 are connected.
[0079] This embodiment also provides a core mounting method, which uses the core mounting fixture described above. The core mounting method includes the following steps:
[0080] S1: Position and install the core 100 onto the adapter 1.
[0081] Specifically, the core 100 and the adapter 1 are first positioned by the positioning pin 11, and then the core 100 is fixedly connected to the adapter 1 by the first fastener 12. After that, the positioning pin 11 can be removed.
[0082] S2: Install the adapter 1 with the core 100 on the frame 21;
[0083] Specifically, the assembly of the core 100 and the adapter 1 is hoisted to the mounting plate 214, so that the lower end and the left end of the adapter 1 abut against the position adjustment component 24 respectively, and the adjusting bolt 241 is turned to adjust the position of the core 100 in the up and down and left and right directions.
[0084] Then, tighten each tilt adjustment bolt 25 to adjust the tilt angle of the adapter 1 relative to the mounting plate 214 so that the core 100 can be aligned with the core mounting position 210.
[0085] Then, the adapter 1 and the mounting plate 1 are connected by the second fastener 13, and the assembly of the core 100 and the adapter 1 is fixed to the mounting plate 214 in the desired posture.
[0086] S3: Move the frame 21 so that it approaches the accelerator body 200 mounted on the accelerator bracket 300 in the direction indicated by the guide 22, so that the core 100 is aligned with the core mounting position 210 on the accelerator body 200. When the front surface of the adapter 1 touches the rear surface of the accelerator body 200, the core 100 reaches the core mounting position 210, the frame 21 stops moving forward, the core 100 is assembled into the core mounting position 210, the fixation between the core 100 and the adapter 1 is released, and the core mounting fixture is removed.
[0087] Specifically, as the frame 21 approaches the accelerator body 200, when the buffer 26 abuts against the accelerator support 300, the frame 21 temporarily stops moving, retracting the buffer 26 away from the accelerator support 300, allowing the buffer 26 to avoid the accelerator support 300, and continues to push the frame 21, causing the core 100 to enter the core mounting position 210; after the core 100 is fully in the core mounting position 210, the frame 21 and the accelerator support 300 are connected by the third fastener 27 to fix the frame 21. Then, the core 100 is connected to the accelerator body 200 by the fourth fastener 110, completing the core 100 assembly. Then, the first fastener 12 is turned to release the connection between the core 100 and the adapter 1, separating the core 100 and the adapter 1. Then, tighten the third fastener 27 to disconnect the connection between the frame 21 and the accelerator bracket 300, and then push the tooling assembly 2 backward away from the accelerator.
[0088] In other embodiments, the core 100 can also be disassembled using the core mounting fixture proposed in this embodiment.
[0089] The core disassembly method includes the following steps:
[0090] S01: Connect and fix the adapter 1 to the mounting plate 214, move the frame 21 so that the frame 21 approaches the accelerator body 200 in the direction indicated by the guide 22. When the vertical frame 212 is in contact with the accelerator bracket 300, the frame 21 stops moving forward and the frame 21 and the accelerator bracket 300 are connected and fixed by the third fastener 27.
[0091] S02: From the rear side of the mounting plate 214, the first fastener 12 is passed through the first clearance hole 2142 to connect the adapter 1 and the core 100.
[0092] S03: Tighten the fourth fastener 110 to disconnect the core 100 and the accelerator body 200.
[0093] S04: Tighten the third fastener 27 to disconnect the frame 21 and the accelerator bracket 300.
[0094] S05: Move the frame 21 backward to remove the core 100 from the accelerator body 200.
[0095] This embodiment also provides an accelerator, as shown in the reference. Figure 1 The accelerator includes an accelerator body 200 and a core 100. The core 100 is assembled inside the accelerator body 200. The core 100 is moved into or out of the accelerator body 200 by the core mounting fixture described above. The core 100 is connected to the accelerator body 200 by a plurality of fourth fasteners 110. The core 100 is configured to be connected to the adapter 1.
[0096] Optionally, the accelerator body 200 is mounted on the accelerator support 300. A guide plate 310 is provided on the side of the accelerator support 300 facing the core mounting fixture to guide the guide member 22 to move in the front-back direction. The guide member 22 moves along the guide plate 310 to guide the movement of the frame 21. Two guide plates 310 are provided, located on the left and right sides of the accelerator support 300 respectively, with each guide plate 310 corresponding to one guide member 22 for guidance.
[0097] Specifically, such as Figure 5 As shown, the guide member 22 includes a guide wheel 221 and a guide fixing plate 222. The guide fixing plate 222 is disposed at the top of the vertical frame 212. The guide wheel 221 is rotatably disposed on the guide fixing plate 222. The guide wheel 221 is used to rotate in the horizontal plane. The guide plates 310 are all provided with inner surfaces for the guide member 22 to move laterally. During the movement of the frame 21, the outer circumferential surface of the guide wheel 221 abuts against the inner surface of the vertically disposed guide plate 310 and rolls forward or backward. The inner surfaces of the two guide plates 310 form a track, which guides the movement direction of the guide wheel 221, thereby causing the frame 21 to move back and forth along the extension direction of the guide plate 310.
[0098] This embodiment also provides a radiotherapy device, which includes the accelerator as described above. In a preferred embodiment, it is a small, integrated proton therapy device that makes proton therapy readily available, which is particularly in line with the trend of technological development.
