Description

Technical Field

[0001] The present application relates to the technical field of radiotherapy, and in particular to an adjustment device, an adjustment method and a loading system for radiotherapy. Background Art

[0002] With the development of atomic science, radiation therapy such as cobalt-60, linear accelerator, and electron beam has become one of the main means of cancer treatment. However, traditional photon or electron therapy is limited by the physical conditions of the reflected rays themselves. While killing tumor cells, it will also cause damage to a large number of normal tissues along the beam path. In addition, due to the different sensitivity of tumor cells to radiation, traditional radiotherapy is often not effective in treating malignant tumors that are more resistant to radiation.

[0003] In order to reduce radiation damage to normal tissues around tumors, targeted therapy in chemotherapy is applied to radiotherapy. For tumor cells with high radiation resistance, radiation sources with high relative biological effects are also being actively developed, such as proton therapy, heavy ion therapy, and neutron capture therapy. Among them, neutron capture therapy combines the above two concepts, such as boron neutron capture therapy, which provides a better cancer treatment option than traditional radiation by specifically aggregating boron-containing drugs in tumor cells and combining with precise neutron beam irradiation.

[0004] Radiotherapy equipment is mainly used for radiotherapy of malignant tumors. The purpose of radiotherapy is to give the target area the maximum radiation treatment while avoiding excessive radiation to surrounding normal tissues. In existing radiotherapy equipment, different irradiated objects usually have different body shapes, and a single irradiated object usually adopts a variety of body position treatment methods. Therefore, it is necessary to use a carrying device to support the irradiated object and position the irradiated object to a preset spatial position. However, in the process of positioning the irradiated object to the preset spatial position by the carrying device, how to quickly and accurately adjust the posture of the irradiated object, how to quickly and accurately position the irradiated object to the preset spatial position, and how to prevent the equipment from aging due to particle radiation are problems that technical personnel in this field need to solve.

[0051] An embodiment of the present application provides a loading system for radiotherapy. In this embodiment, the loading system is preferably applied to radiotherapy equipment, especially boron neutron therapy equipment. The radiotherapy equipment includes a beam generating device, a preparation room, a treatment room, a loading member 1 and an adjustment device 2. When the radiotherapy equipment is a boron neutron therapy equipment, the beam generating device can be a neutron generating device for generating a beam; the treatment room is used for performing radioactive irradiation treatment on the irradiated body; the preparation room can be used for simulating the positioning of the irradiated body or performing other preparations before performing radiation irradiation. Reference Figure 1 As shown, the carrier 1 is used to carry the irradiated object; the adjustment device 2 is used to adjust the posture of the irradiated object in the preparation room and the treatment room, and quickly adjust the irradiated object to a preset spatial position.

[0052] The adjusting device 2 includes an adjusting component 10, a moving component 20, a driving component 30 and an installing component 40. The adjusting component 10 is connected to the mounting part 1 and is used to adjust the spatial position of the mounting part 1 so that the irradiated object is accurately aligned with the beam; the moving component 20 is connected to the adjusting component 10 and is used to move the adjusting component 10 and the mounting part 1; the output end of the driving component 30 is connected to the input end of the adjusting component 10 and is used to drive the adjusting component 10 to adjust so that the mounting part 1 is quickly and accurately adjusted to the preset spatial position, thereby saving the preparation time before the irradiation treatment and avoiding a long time of particle irradiation dose; the installing component 40 is used to connect or separate the adjusting component 10 and the driving component 30 so that there is a gap between the driving component 30 and the adjusting component 10. The drive assembly 30 and the adjustment assembly 10 are detachably connected; when the posture of the irradiated object needs to be adjusted, the drive assembly 30 is connected to the adjustment assembly 10 through the installation assembly 40, and the drive assembly 30 drives the adjustment assembly 10 to adjust the irradiated object to a preset spatial position to perform simulated positioning or irradiation treatment on the irradiated object; when the posture of the irradiated object is adjusted to the preset spatial position, the installation assembly 40 can be loosened to separate the drive assembly 30 and the adjustment assembly 10, and the drive assembly 30 can be removed when performing irradiation treatment, which can effectively prevent the internal mechanical and / or electronic components of the drive assembly 30 from being affected by particle radiation, thereby increasing the service life of the drive assembly 30.

[0053] In other embodiments, the installation assembly 40 may not be provided, as long as a detachable connection can be achieved between the drive assembly 30 and the adjustment assembly 10 so that the drive assembly 30 can be detachably removed to avoid being affected by particle radiation.

[0054] Preferably, the neutron beam N generated by the neutron generating device is sequentially irradiated to the irradiated object on the carrier 1 through the beam shaping body and the collimator. The beam shaping body can adjust the beam quality of the neutron beam N generated by the neutron generating device, and the collimator is usually used to converge the neutron beam N so that the neutron beam N has a higher targeting during the treatment process. It is understandable that the present application may also not have a collimator, that is, the beam directly irradiates the irradiated object on the carrier 1 after coming out of the beam shaping body.

[0055] The preparation room is provided with a simulated beam outlet identical to the beam outlet in the treatment room, and the tumor position of the irradiated body is accurately located and marked by CT images and the like in combination with a laser positioning system, thereby saving the positioning preparation time of the irradiated body in the treatment room. In addition, the preparation room can also be used as a general term for all facilities for performing various steps before treatment and before determining the completion of the positioning, and can include a preparation room for acquiring images, a preparation room for positioning, a preparation room for drug supply, etc. It can be understood that in other embodiments, the preparation room can be set outside or inside the medical facility. It can be understood that the preparation room and the treatment room can be set in the same building of the medical facility or in different buildings.

[0056] Usually, a beam outlet is provided in the treatment room, and the neutron beam passes through the beam outlet to perform beam irradiation therapy on the irradiated body.

[0057] The carrier 1 includes a first support portion 101 and a second support portion 102. The first support portion 101 and the second support portion 102 are installed on the adjustment assembly 10, the first support portion 101 is used to bear the weight of the irradiated body, and the second support portion 102 is used to bear the affected part of the irradiated body. Specifically, the first support portion 101 can be a seat, a treatment plate, a treatment bed, etc., and the second support portion 102 can be a headrest, a headrest, a handrest, a legrest, etc. In this embodiment, preferably, the first support portion 101 is a seat, the second support portion 102 is a headrest, and the second support portion 102 is arranged in front of the first support portion 101. In actual use, the irradiated body sits on the first support portion 101, and the head of the irradiated body is placed on the second support portion 102.

[0058] The preset spatial position of the mounting member 1 is the position of the mounting member 1 where the irradiated object is aligned with the laser or beam. The present application adjusts the spatial position of the mounting member 1 from multiple degrees of freedom, and the multiple degrees of freedom include: a first degree of freedom (such as Figure 1 The second degree of freedom (such as the reciprocating motion parallel to the X axis) Figure 1 The third degree of freedom (rotation about the Z axis) and the fourth degree of freedom (reciprocating motion parallel to the Y axis) Figure 1 The degree of freedom of reciprocating motion parallel to the Z axis). Figure 1 For reference, the direction perpendicular to the mounting surface of the mounting member 1 is defined as the up-down direction (parallel to Figure 1 The Z axis direction shown in FIG. 1 ), the direction parallel to the beam emission direction is the front-to-back direction (parallel to Figure 1 The direction of the Y axis shown in the figure), the direction perpendicular to the up-down direction and the front-back direction is the left-right direction (parallel to Figure 1 In the following description, directional terms such as up, down, left, right, front, and back are used to describe the positional relationship between related elements, so as to simplify the description of the positional relationship between one element and another element, but these directional descriptions do not have any limiting meaning on the technology itself. Specifically, the first degree of freedom is adjusted to move along the left-right direction of the irradiated body, the second degree of freedom is adjusted to move along the front-back direction of the irradiated body, the third degree of freedom is adjusted to rotate the irradiated body with a straight line parallel to the up-down direction as the axis; the fourth degree of freedom is adjusted to move along the up-down direction of the irradiated body.

[0059] refer to Figure 2As shown, the adjustment component 10 includes a first adjustment unit 11, a second adjustment unit 12, a third adjustment unit 13 and a fourth adjustment unit 14. Preferably, the output end of the first adjustment unit 11 is connected to the input end of the second adjustment unit 12, and is used to adjust the carrier 1 to drive the object / irradiated body to move along the first degree of freedom; further, the output end of the second adjustment unit 12 is connected to the input end of the third adjustment unit 13, and is used to adjust the carrier 1 to drive the object / irradiated body to move along the second degree of freedom; further, the output end of the third adjustment unit 13 is connected to the input end of the fourth adjustment unit 14, and is used to adjust the carrier 1 to drive the object / irradiated body to move along the third degree of freedom; further, the output end of the fourth adjustment unit 14 is connected to the carrier, and is used to adjust the carrier 1 to drive the object / irradiated body to move along the fourth degree of freedom. Preferably, the first adjustment unit 11, the second adjustment unit 12, the third adjustment unit 13, and the fourth adjustment unit 14 in this embodiment are arranged in sequence from bottom to top, and the fourth adjustment unit 14 is located at the topmost layer and is connected to the carrier 1. In terms of the integration of the structure and the convenience of the driving process, this arrangement has the smallest space occupancy and the most convenient driving process.

[0060] Preferably, any two adjacent adjustment units can be linked, that is, driving the adjustment unit of the lower layer can drive the adjustment unit and the carrier 1 of the upper layer to move, and the movement of the adjustment unit of the upper layer preferably does not drive the adjustment unit of the lower layer to move, so as to facilitate the control and adjustment of each adjustment unit. It is easy to understand that driving the adjustment unit of the lower layer means: driving the input end of the adjustment unit of this layer to move, rather than driving the adjustment unit of this layer as a whole to move in a certain direction.

[0061] Specifically, the first adjustment unit 11 is linked with the second adjustment unit 12, that is, the first adjustment unit 11 is driven to move, which can drive the second adjustment unit 12, the third adjustment unit 13, the fourth adjustment unit 14 and the carrier 1 to move along the first degree of freedom at the same time; the second adjustment unit 12 is linked with the third adjustment unit 13, that is, the second adjustment unit 12 is driven to move, which can drive the third adjustment unit 13, the fourth adjustment unit 14 and the carrier 1 to move along the second degree of freedom at the same time; the third adjustment unit 13 is linked with the fourth adjustment unit 14, that is, the third adjustment unit 13 is driven to move, which can drive the fourth adjustment unit 14 and the carrier 1 to rotate along the third degree of freedom at the same time; the fourth adjustment unit 14 is connected to the carrier 1, that is, the fourth adjustment unit 14 is driven to move, which can drive the carrier 1 to move along the fourth degree of freedom. The arrangement and adjustment method of the adjustment unit realizes the adjustment of the carrier 1 in four degrees of freedom, so that the carrier 1 is adjusted to a preset spatial position for beam irradiation therapy.

[0062] In a preferred embodiment, the adjustment between the adjustment units follows a certain order, and driving the second adjustment unit 12 to move will not affect the position of the first adjustment unit 11; similarly, driving the third adjustment unit 13 to move will not affect the positions of the first adjustment unit 11 and the second adjustment unit 12; driving the fourth adjustment unit 13 to move will not affect the positions of the first adjustment unit 11, the second adjustment unit 12 and the third adjustment unit 13. In this way, in the case of multiple degrees of freedom adjustment, each degree of freedom can be adjusted accurately one by one as needed, reducing the impact of the adjustment of each adjustment unit.

[0063] In other embodiments, the first adjustment unit 11, the second adjustment unit 12, the third adjustment unit 13 and the fourth adjustment unit 14 can also adopt other arrangement orders, that is, the arrangement order between them is not limited, as long as the linkage effect can be achieved, for example, from bottom to top, they can be arranged in the order of second, first, fourth, and third. In addition, in other embodiments, any two groups or any three groups can be selected from the first adjustment unit 11, the second adjustment unit 12, the third adjustment unit 13 and the fourth adjustment unit 14 for combination, and the arrangement order is not limited, as long as the linkage effect can be achieved. The hierarchically designed adjustment component 10 can achieve targeted single-layer or multi-layer adjustment by arbitrarily adjusting one or more of the first adjustment unit 11, the second adjustment unit 12, the third adjustment unit 13 and / or the fourth adjustment unit 14, and smoothly and accurately adjust the posture of the irradiated body in a single or multiple degrees of freedom, reducing the time for repeated operations and verification adjustments, thereby shortening the preparation time for positioning the affected part, simplifying the preparation work, and improving the accuracy of irradiation treatment.

[0064] refer to Figure 3 As shown, the first adjustment unit 11 includes a first adjustment member 111, a first transmission member 112, a first support member 113 and a first guide member 114.

[0092] Further, the first driving member 311 and the second driving member 312 are linked to each other, that is, when the first driving member 311 is working, the second driving member 312 can be moved along the first path. When the second driving member 312 is working, the second driving member 312 itself can move along the second path. The second driving member 312 and the third driving member 313 are linked to each other, that is, when the second driving member 312 is working, the third driving member 313 can follow the second driving member 312 to move along the second path. The linkage process of the three driving members is described below.

[0093] In a preferred embodiment, the second driving member 312 does not affect the position of the first driving member 311 when it is working; similarly, the third driving member 313 does not affect the positions of the first driving member 311 and the second driving member 312 when it is working. In this way, the driving assembly 30 can accurately drive the adjustment assembly 10 one by one as needed to realize the movement of the carrier 1 in multiple degrees of freedom.

The first driving part 3111 is used to provide driving force; the first transmission part 3112 is connected between the first driving part 3111 and the second transmission part 3113, and the first transmission part 3112 is used to transmit the power of the first driving part 3111 to the second transmission part 3113; the second transmission part 3113 is used to rotate with the first driving part 3111; the first output part 3114 is connected to the end of the second transmission part 3113, and is used to output the power of the first driving part 3111 to drive the first operating part 1111 to rotate; the first moving part 3115 is transmission-connected to the second transmission part 3113, and is connected to the second driving member 312, and is used to drive the second driving member 312 and the third driving member 313 to move.

[0095] Further, the first driving part 3111 is mounted on the eighth mounting seat 3116, and a shaft is provided at the end of the first driving part 3111. The first transmission part 3112 includes a first transmission wheel 3112a, a second moving wheel 3112b and a transmission belt 3112c. The first transmission wheel 3112a is arranged on the shaft of the first driving part 3111, the second moving wheel 3112b is arranged at one end of the second transmission part 3113, and the transmission belt 3112c is meshed with the first transmission wheel 3112a and the second moving wheel 3112b, and is used to transmit the driving force of the first driving part 3111 to the second transmission part 3113.

[0096] Further, the second transmission part 3113 can be arranged side by side with the first driving part 3111, which can save space and make the structure compact. One end of the second transmission part 3113 is also installed on the eighth mounting seat 3116. The second transmission part 3113 can be a screw rod, and the first moving part 3115 is threadedly connected to the second transmission part 3113. Under the action of the first driving part 3111 and the first transmission part 3112, the second transmission part 3113 rotates, so that the first moving part 3115 moves along the axis where the second transmission part 3113 is located. The first moving part 3115 is connected to the fourth supporting part 3124, and the movement of the first moving part 3115 is used to drive the second driving member 312 and the third driving member 313 to move (described in detail below).

[0097] Furthermore, the first output part 3114 is connected to the end of the second transmission part 3113, and a sleeve for transmitting power is provided at the end of the first control part 1111 close to the first output part 3114, and the first output part 3114 is connected to the first control part 1111 through the sleeve. Under the action of the first driving part 3111, the first control part 1111 is rotated through the first output part 3114, so that the second adjustment unit 12, the third adjustment unit 13, the fourth adjustment unit 14 and the carrier 1 can move along the first degree of freedom.

[0098] In the embodiment disclosed in the present application, the lead of the second transmission part 3113 is preferably the same as the lead of the first adjustment part 1112. Fig.14 The second transmission part 3113 and the first adjusting part 1112 preferably use the same threaded rod. The second transmission part 3113 and the first movable part 3115 are arranged in combination with the limiter 314 to limit the moving path of the first transmission part 112. The moving stroke of the first movable part 3115 on the second transmission part 3113 is the same as the moving stroke of the first transmission part 112 on the first adjusting part 1112. When the first movable part 3115 moves to the end of the second transmission part 3113, it represents that the first transmission part 112 reaches the upper limit of movement, that is, the second adjusting unit 12 reaches the upper limit of adjustment in the first degree of freedom. At this time, the first movable part 3115 will contact the limiter 314. Under the action of the limiter 314, the first driving part 3111 idles or stops rotating, so that the second adjusting unit 12 stops moving, thereby ensuring the safe operation of the entire device within the adjustable range.

[0099] refer to Fig.12 , Fig.13 and Fig.14As shown, the second driving member 312 includes a second driving portion 3121, a second output portion 3122, a third supporting portion 3123, a fourth supporting portion 3124, a first guiding portion 3125 and a second guiding portion. The second driving part 3121 is used to provide driving force; the second output part 3122 is connected to the output end of the second driving part 3121, and is used to output the power of the second driving part 3121 to drive the second operating part 1211 to rotate; the third supporting part 3123 is connected to the second driving part 3121, and is used to install the second driving part 3121; the fourth supporting part 3124 is connected to the first moving part 3115, and is used to move with the first moving part 3115; the first guiding part 3125 is arranged on the fourth supporting part 3124, and is connected between the fourth supporting part 3124 and the base 315, and the first guiding part 3125 is used to guide the second driving part 3121 to move along the first path defined by the first guiding part 3125; the second guiding part is arranged on the third supporting part 3123, and is connected between the third supporting part 3123 and the fourth supporting part 3124, and the second guiding part is used to guide the second driving part 3121 to move along the second path defined by the second guiding part.

[0100] Furthermore, a sleeve is provided at the end of the second manipulation part 1211 close to the second output part 3122, and the second output part 3122 is connected to the second manipulation part 1211 through the sleeve. Under the action of the second driving part 3121, the second output part 3122 drives the second manipulation part 1211 to rotate, so as to realize the movement of the third adjustment unit 13, the fourth adjustment unit 14 and the carrier 1 along the second degree of freedom.

[0101] Further, the first guide portion 3125 includes a fifth slider 3125a and a fifth guide rail 3125b, and the fifth slider 3125a and the fifth guide rail 3125b can also be arranged in pairs on the base 315. The second guide portion includes a sixth guide rail 3126. Preferably, the third support portion 3123, the second guide portion, the fourth support portion 3124, and the first guide portion 3125 are arranged on the base 315 in sequence from top to bottom. The second driving part 3121 is mounted on the third supporting part 3123 through the ninth mounting seat 3127. The bottom of the third supporting part 3123 is connected to the sixth slider (not shown), the sixth slider is slidably connected to the sixth guide rail 3126, and the sixth guide rail 3126 is connected to the fourth supporting part 3124. The bottom of the fourth supporting part 3124 is connected to the fifth slider 3125a, the fifth slider 3125a is slidably connected to the fifth guide rail 3125b, and the fifth guide rail 3125b is fixedly connected to the base 315. The bottom of the fourth supporting part 3124 is connected to the first moving part 3115, and is used to move with the first moving part 3115. Preferably, the straight line where the fifth guide rail 3125b is located is perpendicular to the straight line where the sixth guide rail 3126 is located. With reference to the settings of the multiple degrees of freedom in the aforementioned adjustment component 10, in the embodiment disclosed in the present application, the straight line where the fifth guide rail 3125b is located is parallel to the first degree of freedom, and the second drive unit 3121 moves through the fifth guide rail 3125b, that is, the second drive unit 3121 moves along the first path; the straight line where the sixth guide rail 3126 is located is parallel to the second degree of freedom, and the second drive unit 3121 moves through the sixth guide rail 3126, that is, the second drive unit 3121 moves along the second path. When the first driving part 3111 drives the first manipulating part 1111 to rotate, the first transmission member 112 moves along the axis where the first adjusting part 1112 is located, driving the second adjusting unit 12 to move along the first degree of freedom, and at the same time, the first moving part 3115 also moves along the axis where the second transmission part 3113 is located, that is, the first moving part 3115 synchronously follows the movement of the second adjusting unit 12, and the first moving part 3115 is connected to the fourth supporting part 3124, thereby, the fourth supporting part 3124 also follows the movement of the second adjusting unit 12, so that the second driving part 3121 moves along the first path, so that the second output part 3122 will not be separated from the second manipulating part 1211, that is, the second output part 3122 will not be separated from the sleeve of the second manipulating part 1211, thereby failing to drive the second manipulating part 1211. Specifically, the first guiding part 3125 is used to guide the fourth supporting part 3124 to move along the first path.When the second driving part 3121 drives the second manipulating part 1211 to rotate, the second manipulating part 1211, the second adjusting part 1212, the second transmission member 122 and the third supporting member 133 move together along the second degree of freedom, and the second driving part 3121 also moves along the second path, so that the second output part 3122 will not be separated from the second manipulating part 1211, that is, the second output part 3122 will not be separated from the sleeve of the second manipulating part 1211, thereby failing to drive the second manipulating part 1211. Specifically, the second guide part is used to guide the second driving part 3121 and drive the second output part 3122 to move along the second path.

[0102] refer to Fig.14 As shown, the third driving member 313 includes a third driving part 3131, a second transmission part 3132, a third transmission part 3133, a third output part 3134 and a second moving part 3135. The third driving part 3131 is used to provide driving force; the second transmission part 3132 is connected between the third driving part 3131 and the third transmission part 3133, and is used to transmit the power of the third driving part 3131 to the third transmission part 3133. The second transmission part 3132 in the third driving member 313 is basically the same as the first transmission part 3112 in the first driving member 311 in structure and function, and will not be repeated here. The third output part 3134 is connected to the end of the third transmission part 3133, and is used to output the power of the third driving part 3131 to drive the third operating part 1311 to rotate; the third transmission part 3133 and the second moving part 3135 are combined with the limiting member 314 to limit the motion path of the first transmission part 1313 (described in detail below).

[0103] Further, the third driving part 3131 is mounted on the third supporting part 3123 through the tenth mounting seat 3136, and the third transmission part 3133 is mounted on the third supporting part 3123 through the eleventh mounting seat 3137. The third output part 3134 is located at the end of the third transmission part 3133, and the third output part 3134 is connected to the third operating part 1311 through the sleeve.

[0104] Further, when the first driving part 3111 drives the first control part 1111 to rotate, the second adjustment unit 12 and the third adjustment unit 13 move along the first degree of freedom, and the second driving part 3121 and the third driving part 3131 move along the first path through the first guide part 3125; when the second driving part 3121 drives the second control part 1211 to rotate, part of the second adjustment unit 12 and the third adjustment unit 13 move along the second degree of freedom, and the second driving part 3121 and the third driving part 3131 move along the second path through the second guide part 3126; when the third driving part 3131 drives the third control part 1311 to rotate, the fourth adjustment unit 14 moves along the third degree of freedom. That is to say, preferably, at least the first output part and the first control part are not separated, and further, the second output part and the second control part are not separated, and the third output part and the third control part are not separated. In this way, during the adjustment process, the drive assembly 30 can reliably and continuously adjust the adjustment assembly 10 without the need to manually frequently dock different output shafts to achieve adjustment, saving operation time.

[0105] Preferably, in the embodiment disclosed in the present application, the lead of the third transmission part 3133 is preferably the same as the lead of the third adjustment part 1312. Specifically, the third transmission part 3133 and the third adjustment part 1312 preferably use the same threaded rod, the second moving part 3135 is threadedly connected to the third transmission part 3133, and the moving stroke of the second moving part 3135 on the third transmission part 3133 is the same as the moving stroke of the first transmission part 1313 on the third adjustment part 1312. When the second moving part 3135 moves to the end of the third transmission part 3133, it means that the first transmission part 1313 reaches the upper limit of movement in the second degree of freedom, that is, the third adjustment unit 13 reaches the upper limit of adjustment. At this time, the second moving part 3135 will contact the limit member 314. Under the action of the limit member 314, the third driving part 3131 idles or stops rotating, so that the third adjustment unit 13 stops moving, ensuring the operation safety of the entire device within the adjustable range.

[0106] Furthermore, the limit member 314 includes a sensing switch 3141 and a limit shaft. Preferably, the sensing switch 3141 is used as a soft limit, and the limit shaft is used as a hard limit, which are arranged on the first drive member 311, the second drive member 312 and the third drive member 313, and the movement stroke of the first adjustment unit 11, the second adjustment unit 12 and the third adjustment unit 13 is double-limited, so that they cannot continue to adjust when they reach the upper limit of adjustment, thereby ensuring the safe operation of the device. It is understandable that only the sensing switch 3141 or the limit shaft can be set, or both can be set. In the embodiments disclosed in the present application, the setting scheme of the limit member 314 is described in combination with the third drive member 313. The setting of the limit member 314 of the first drive member 311 and the second drive member 312 is basically the same as the setting of the limit member 314 on the third drive member 313 in terms of mode and principle, which will not be repeated here.

[0107] Further, the induction switch 3141 is mounted on the third support portion 3123, and two induction switches 3141 may be provided, and the two induction switches 3141 are respectively located on the sides of the two eleventh mounting seats 3137, respectively corresponding to the two ends of the third transmission portion 3133. When the second moving portion 3135 moves along the third transmission portion 3133 to one end of the third transmission portion 3133, the second moving portion 3135 contacts the induction switch 3141, indicating that the third adjustment unit 13 reaches the upper limit of adjustment, and at this time, the third driving portion 3131 can be stopped from driving by powering off, so that the first transmission portion 1313 stops moving.

[0108] Further, the limiting shaft includes a first limiting shaft 3142 and a second limiting shaft 3143, the first limiting shaft 3142 is mounted on the eleventh mounting seat 3137, and the second limiting shaft 3143 is mounted on the second moving part 3135. When the second moving part 3135 moves along the third transmission part 3133 to one end of the third transmission part 3133, the second moving part 3135 abuts against the first limiting shaft 3142 or the second limiting shaft 3143 abuts against the eleventh mounting seat 3137, which means that the third adjustment unit 13 reaches the upper limit of adjustment, and at this time, the third driving part 3131 idles, so that the first transmission part 1313 stops moving.

[0109] Furthermore, the second movable member 320 is arranged around the bottom of the base 315 to facilitate the movement of the entire first driving assembly 31. The second movable member 320 can be a pulley, a caster, a roller, a universal wheel, etc.

[0110] Furthermore, the second driving assembly includes a fourth driving member. The fourth driving member is provided separately, and a fourth output portion of the fourth driving member is connected to the fourth operating portion 1411 through a sleeve.

[0111] refer to Fig.15As shown, the mounting assembly 40 includes a first mounting member 41 and a second mounting member 42. The first mounting member 41 and the second mounting member 42 are preferably detachably connected to achieve a detachable connection and fixation between the adjustment assembly 10 and the first drive assembly 31. The first mounting member 41 matches the second mounting member 42 and the mounting positions correspond to each other. The first mounting member 41 can be installed on the adjustment assembly 10, and the second mounting member 42 can be installed on the first drive assembly 31; or, the first mounting member 41 can also be installed on the first drive assembly 31, and the second mounting member 42 can also be installed on the adjustment assembly 10. In the embodiment disclosed in the present application, two first mounting members 41 are provided, and the two first mounting members 41 are respectively installed on both sides of the first drive assembly 31, and two second mounting members 42 are provided, and the two second mounting members 42 are respectively installed on both sides of the adjustment assembly 10.

[0112] The second drive assembly can also be installed using the installation assembly 40 of the present application. It is understandable that other installation devices can also be used for installation.

[0113] In the embodiment disclosed in the present application, the first mounting member 41 includes a first mounting portion 411, an operating portion 412 and a clamping portion 413. The first mounting portion 411 is preferably mounted on the side of the base 315 of the first driving assembly 31, the operating portion 412 is disposed on the first mounting portion 411, the clamping portion 413 is connected to the operating portion 412, and the operating portion 412 is used to drive the clamping portion 413 to clamp with the fixing portion 422 of the second mounting member 42.

[0114] The second mounting member 42 includes a second mounting portion 421 and a fixing portion 422. The second mounting portion 421 is preferably mounted on the bottom side of the adjustment assembly 10, and the fixing portion 422 is disposed on the second mounting portion 421, and the fixing portion 422 is used to fix the clamping portion 413. The clamping portion 413 has two positions, including a clamping position and a release position. When the clamping portion 413 is in the clamping position, the adjustment assembly 10 and the first drive assembly 31 are locked; when the clamping portion 413 is in the release position, the adjustment assembly 10 and the first drive assembly 31 are disengaged. The operating portion 412 can operably drive the clamping portion 413 to move between the clamping position and the release position. Preferably, the clamping portion 413 has an annular structure and the fixing portion 422 is in a hook shape; when the spatial position of the carrier 1 needs to be adjusted, the first drive component 31 is moved close to the installation position of the adjustment component 10, and the clamping portion 413 is driven to approach the fixing portion 422 through the operating portion 412, so that the hollow annular structure of the clamping portion 413 passes through the hook-shaped fixing portion 422, and then the operating portion 412 is moved away from the clamping portion 413 and locked. The fixing portion 422 can stop the clamping portion 413 from disengaging from it, so as to maintain the clamping portion 413 in the clamping position. At this time, the clamping portion 413 is in the clamping position, so that the first drive component 31 is fixed relative to the adjustment component 10, thereby realizing the connection and fixation between the first drive component 31 and the adjustment component 10. When the carrier 1 is adjusted to a preset spatial position, the driving operating part 412 approaches the fixing part 422, and the clamping part 413 is separated from the fixing part 422. At this time, the clamping part 413 is in a released position, so that the first driving component 31 can be moved relative to the adjusting component 10, thereby realizing the separation of the first driving component 31 from the adjusting component 10.

[0115] An embodiment of the present application provides a method for adjusting a regulating device, the method comprising:

[0116] S100 , the first drive assembly 31 and / or the second drive assembly (not shown) are connected and fixed to the adjustment assembly 10 from a separated state through the installation assembly 40 .

[0117] In actual operation, S100 includes the following methods:

[0118] S101, move the carrier 1 to the preparation room.

[0119] S102, positioning the first driving assembly 31 to an installation position.

[0120] Combination Figure 8 and Fig.16As shown, a positioning member 318 is further provided on the base 315 of the first driving component 31, and a positioning hole 153 is correspondingly provided on the bottom of the adjusting component 10. The positioning hole 153 matches the positioning member 318 and is used to pre-position the first driving component 31 to the installation position, which is conducive to the subsequent positioning by the installation component 40. A second moving member 320 is provided between the first driving member 311 and the base 315, and a third moving member 319 enables the first driving member 311 to be movable relative to the base 315 to achieve manual position adjustment.

[0121] The third moving member 319 includes a connecting block 3191, a seventh slider 3192, a seventh guide rail 3193, a pull rod 3194, a twelfth mounting seat 3195, a limit block 3196, a positioning block 3197 and a reset member 3198. The connecting block 3191 is connected to the eighth mounting seat 3116, the bottom of the connecting block 3191 is connected to the seventh slider 3192, the seventh slider 3192 is slidably connected to the seventh guide rail 3193, and the seventh guide rail 3193 is connected to the base 315, so that the first driving member 311 can be operably moved relative to the base 315. The axis of the seventh guide rail 3193 is preferably parallel to the first degree of freedom, so that the first driving member 311 drives the first output portion 3114 to move along the first path. The connecting block 3191 is connected to one end of the pull rod 3194, the pull rod 3194 passes through the twelfth mounting seat 3195, the twelfth mounting seat 3195 is fixed to the base 315, the limit block 3196 is rotatably connected to the pull rod 3194, the positioning block 3197 is spaced apart from the twelfth mounting seat 3195, and the reset member 3198 is sleeved on the pull rod 3194 and located between the connecting block 3191 and the twelfth mounting seat 3195. It is easy to understand that the reset member 3198 can be selected from a spring, a torsion spring, a biasing structure, etc. The pull rod 3194 is used to pull the connecting block 3191 to move the first driving member 311 along the first path, and then rotate the limit block 3196 to make it abut against the positioning block 3197. At this time, the first driving member 311 is farther away from the adjusting component 10 than the positioning member 318. When the positioning member 318 matches the positioning hole 153, it can avoid the first output part 3114 of the first driving member 311 from colliding with the adjusting component 10 in the case of misalignment, causing unnecessary damage to components.

[0122] S103, drive the clamping part 413 to approach the fixing part 422 through the operating part 412, so that the annular structure of the clamping part 413 passes through the fixing part 422, and then move the operating part 412 away from the clamping part 413, and the fixing part 422 stops the clamping part 413 from disengaging from it. At this time, the first driving component 31 is fixed relative to the adjusting component 10.

[0127] S201 , rotating the limit block 3196 to separate the limit block 3196 and the positioning block 3197 from each other, and the reset member 3198 resets the connection block 3191 . At this time, the first output portion 3114 can be adjusted to dock with the first operating portion 1111 .

[0128] S202, move the second driving member 312 and the third driving member 313 along the second path so that the second output part 3122 and the third output part 3134 are roughly aligned with the second control part 1211 and the third control part 1311; further, move the second driving member 312 and the third driving member 313 along the first path so that the second output part 3122 and the third output part 3134 are connected to the second control part 1211 and the third control part 1311.

[0129] S203 , if there is a fourth output unit, connect the fourth output unit to the fourth control unit 1411 .

[0133] It is understandable that, in the above method, the control order of the first driving member 311, the second driving member 312, the third driving member 313, and the fourth driving member is not limited.

[0134] S400, the drive assembly 30 is separated from the adjustment assembly 10 through the installation assembly 40. Specifically, the driving operation part 412 is close to the fixing part 422, and the clamping part 413 is separated from the fixing part 422, and the first drive assembly 31 and / or the second drive assembly can be separated from the adjustment assembly 10.

[0135] The adjustment component 10 and the driving component 30 are moved to the treatment room, and the above methods S100, S200, S300, and S400 are repeated to adjust the adjustment component 10 to the corresponding position, and then the driving component 30 is moved out of the treatment room, and finally the irradiated body is irradiated with the beam.
