[0002] Existing radiotherapy devices are usually provided with particle accelerators, which need to rotate relative to the isocenter of the treatment room during use. The particle accelerator can be installed on a rotating gantry, and then the rotating gantry is driven by a motor to rotate around a rotation axis. The particle accelerator will rotate synchronously with the rotating gantry around the rotation axis, and at the same time, the particle accelerator will move around the isocenter of the treatment room.

[0003] During the process of the motor driving the rotating gantry to rotate, if the center of mass of the overall components such as the rotating gantry and the particle accelerator installed on the rotating gantry deviates from the rotation axis, it will cause the motor to bear an additional balancing torque during the process of driving the rotating gantry and the particle accelerator to rotate around the rotation axis due to the deviation of the center of mass of the overall components such as the rotating gantry and the particle accelerator installed on the rotating gantry, thereby reducing the service life of the motor.

Detailed Embodiments

[0054] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in various forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this invention will be more complete and comprehensive, and will fully convey the concept of the example embodiments to those skilled in the art. Like reference numerals in the figures denote the same or similar structures, and thus their repetitive description will be omitted.

[0055] In the present invention, the words expressing position and direction are described with reference to the accompanying drawings as examples, but can be changed according to needs, and all changes made are included in the protection scope of the present invention.

[0056] As Figure 1 and Figure 2As shown, the present invention provides a particle therapy device 100, comprising a rotating frame 1 for rotating relative to a part of a patient to be treated, a rotating assembly 2 for driving the rotating frame 1 to rotate, a particle accelerator 3 and a counterweight unit 4 installed on opposite sides of the rotating frame 1, and an adjustment assembly 5 for adjusting the position of the counterweight unit 4. The particle accelerator 3 is used to provide a particle beam to treat the part of the patient to be treated, such as a tumor. The counterweight unit 4 is mainly composed of an object with a certain weight, for example, the counterweight unit 4 includes one or more counterweight blocks.

[0057] The rotating gantry 1 can also be used to install the rotating assembly 2. The rotating assembly 2 can be located between the particle accelerator 3 and the counterweight unit 4. When the rotating gantry 1 is connected to the rotating assembly 2, the rotating gantry 1 can rotate around a rotating axis 21 driven by the rotating assembly 2, and the treatment device installed on the rotating gantry 1 will rotate along with the rotating gantry 1.

[0058] The rotating frame 1 may specifically include a support arm 12, a connecting cylinder 15 and a mounting frame 11. A pair of support arms 12 may be provided, and the pair of support arms 12 are arranged at a relative interval. A pair of connecting cylinders 15 may be provided, and the pair of connecting cylinders 15 are both located at the same end of the support arm 12, each connecting cylinder 15 may be fixedly connected to a support arm 12, and the connecting cylinder 15 is arranged on the side of the support arm 12 connected to the connecting cylinder 15 facing the other support arm 12. The two connecting cylinders 15 may be connected to the particle accelerator 3 together, so that the particle accelerator 3 is fixed between the two connecting cylinders 15, and the particle accelerator 3 is located between the pair of support arms 12, and the particle accelerator 3 and the connecting cylinder 15 are located at the same end of the support arm 12. The support arm 12 and the connecting cylinder 15 may be connected by bolts or other fixing parts, or by welding, bonding, clamping, etc., which are not limited here; the connecting cylinder 15 and the particle accelerator 3 may be connected by bolts or other fixing parts, or by bonding, clamping, etc., which are not limited here. The pair of connecting cylinders 15 realizes reliable fixation of the particle accelerator 3, making the particle therapy device more compact and beautiful.

[0059] The mounting frame 11 is arranged at one end of the support arm 12 away from the connecting cylinder 15, and a pair of mounting frames 11 may be provided, each mounting frame 11 is fixedly connected to a support arm 12, and each mounting frame 11 may be used to connect a counterweight unit 4. The mounting frame 11 and the support arm 12 may be fixedly connected by a fixing member such as a bolt, or may be fixed by welding, bonding, clamping, etc., which are not limited here. The support arm 12 may also be called a machine arm or a side arm, and the connecting cylinder 15 may also be called an intermediate arm.

[0060] The rotating assembly 2 may include a rotating member 22 and a rotation driving member (not shown in the figure) connected to the rotating member 22. The rotation driving member is used to drive the rotating member 22 to rotate. The rotating member 22 may be connected to the rotating frame 1 to drive the rotating frame 1 to rotate along the central axis of the rotating member 22, that is, the central axis of the rotating member 22 forms the rotation axis 21 of the rotating frame 1. One rotating member 22 may be connected to one rotation driving member or multiple rotation driving members. When one rotating member 22 is connected to multiple rotation driving members, the multiple rotation driving members are jointly used to drive the rotating member 22 to rotate in the same direction. For example, when one rotating member 22 is connected to two rotation driving members, the two rotation driving members may be oppositely connected to the rotating member 22 to jointly drive the rotating member 22 to rotate in the same direction. Among them, the rotating member 22 may be a rotating gear, and the rotating gear may be fixedly connected to the rotating frame 1 to drive the rotating frame 1 to rotate synchronously. The rotation driving member may include a motor and a driving gear sleeved on the output shaft of the motor. The driving gear meshes with the rotating gear. When the output shaft of the motor rotates, the driving gear sleeved on the output shaft of the motor will drive the rotating gear to rotate.

[0061] In some specific embodiments, the rotating member 22 of the rotating assembly 2 may be fixedly connected to the support arm 12. Only one of the pair of support arms 12 may be connected to the rotating assembly 2, or each support arm 12 may be connected to a rotating assembly 2. And when each support arm 12 is connected to a rotating assembly 2, the central axes of the pair of rotating members 22 in the pair of rotating assemblies 2 connected to the pair of support arms 12 coincide, so that the pair of rotating assemblies 2 drive the rotating frame 1 to rotate along the same rotation axis 21.

[0062] In some specific embodiments, the installation position of the rotating assembly 2 and the support arm 12 may be at the central position of the support arm 12 or near the central position of the support arm 12. Specifically, in this embodiment, the rotating assembly 2 may be arranged near the center point of the support arm 12 along the length direction of the support arm 12, and the rotating assembly 2 may be arranged on the side of the center point of the support arm 12 along the length direction of the support arm 12 facing the mounting frame 11.

[0063] After the rotating frame 1 is connected to the rotating assembly 2, the particle therapy device 100 can form a lever structure. The rotation axis 21 of the rotating frame 1 corresponds to the fulcrum of the lever structure. The particle accelerator 3 and the counterweight unit 4 are arranged on opposite sides of the rotation axis 21, that is, the particle accelerator 3 and the counterweight unit 4 apply main forces at opposite ends in the lever structure. When the forces at both ends of the lever structure are the same (the force magnitudes and directions are the same), the lever structure is in a balanced state, that is, the particle therapy device 100 is in a balanced state. At this time, when the rotating assembly 2 drives the rotating frame 1 to rotate, it does not need to bear the balance torque generated due to the offset between the center of mass of the particle therapy device 100 and the rotation axis 21 (the fulcrum of the lever structure) of the rotating frame 1, greatly extending the service life of the rotating assembly 2 and the particle therapy device. Moreover, it can also prevent the rotating assembly 2 from vibrating due to this balance torque, avoiding affecting the pre-set transmission path of the particle beam of the particle accelerator 3, ensuring the accurate transmission of the particle beam to the treatment site to be treated, and ensuring the treatment accuracy and treatment effect of the particle therapy device 100, thus benefiting patients.

[0064] Among them, the force at the end of the lever structure corresponding to the particle accelerator 3 is mainly provided by the gravity of the particle accelerator 3 and the connecting cylinder 15. At the same time, the force at the end of the lever structure corresponding to the particle accelerator 3 also includes the gravity generated by the connecting parts for connecting the particle accelerator 3 and the connecting cylinder 15, the connecting parts for connecting the connecting cylinder 15 and the support arm 12, and the part of the support arm 12 on the side facing the particle accelerator 3 of the fulcrum of the lever structure. The force at the end of the lever structure corresponding to the counterweight unit 4 is mainly provided by the gravity of the counterweight unit 4. At the same time, the force at the end of the lever structure corresponding to the counterweight unit 4 also includes the gravity generated by the connecting parts for connecting the counterweight unit 4 and the support arm 12, and the part of the support arm 12 on the side facing the counterweight unit 4 of the fulcrum of the lever structure.

[0065] Referring to Figure 2 , the adjustment assembly 5 is directly or indirectly connected to the counterweight unit 4 and the rotating frame 1. For example, the adjustment assembly 5 can be directly installed on the rotating frame 1 and directly abutted against the counterweight unit 4 to achieve the direct connection between the adjustment assembly 5, the counterweight unit 4, and the rotating frame 1; or the adjustment assembly 5 can be installed on a component fixed to the rotating frame 1, and the adjustment assembly 5 can abut against a component that fits with the counterweight unit 4, thereby achieving the indirect connection between the adjustment assembly 5, the counterweight unit 4, and the rotating frame 1.

[0066] The adjustment assembly 5 is used to adjust the distance between the counterweight unit 4 and the rotating shaft 21 to balance the particle therapy device 100. Specifically, when the adjustment assembly 5 adjusts the position of the counterweight unit 4, the distance between the counterweight unit 4 and the rotating shaft 21 will be adjusted, that is, the force arm between the counterweight unit 4 and the fulcrum of the lever structure will be changed. The main component of the acting force at one end of the lever structure corresponding to the counterweight unit 4 is generated by the gravity of the counterweight unit 4. The acting force generated by the gravity of the counterweight unit 4 is equal to the product of the gravity of the counterweight unit 4 and the force arm between the counterweight unit 4 and the fulcrum of the lever structure. Therefore, by adjusting the force arm between the counterweight unit 4 and the rotating shaft 21, the acting force at one end of the lever structure corresponding to the counterweight unit 4 can be changed, so that the acting force at one end of the lever structure corresponding to the counterweight unit 4 is adjusted to be the same as the acting force at one end of the lever structure corresponding to the particle accelerator 3, and then the particle therapy device 100 is adjusted to a balanced state.

[0067] Referring to Figure 3 and Figure 4 , in some specific embodiments, the adjustment assembly 5 includes an ejector 51 movably connected to the mounting bracket 11. Specifically, the mounting bracket 11 may be provided with a connection hole 111 that cooperates with the ejector 51. One end of the ejector 51 passes through the connection hole 111 of the mounting bracket 11 and abuts against the counterweight unit 4. When the end of the ejector 51 that abuts against the counterweight unit 4 further moves to protrude from the mounting bracket 11, the ejector 51 will push the counterweight unit 4 that abuts against it to move away from the mounting bracket 11, so as to adjust the relative position of the counterweight unit 4 and the mounting bracket 11, and further adjust the force arm between the counterweight unit 4 and the rotating shaft 21. Among them, the cooperation position between the ejector 51 and the mounting bracket 11 can be manually adjusted. For example, the ejector 51 is a set screw, and the connection hole 111 is a threaded hole that cooperates with the ejector 51. By screwing the ejector 51, the cooperation position between the ejector 51 and the mounting bracket 11 can be adjusted.

[0068] The adjustment assembly 5 may include a plurality of ejectors 51. The plurality of ejectors 51 may be symmetrically distributed with respect to the central position of the corresponding counterweight unit 4, so that the plurality of ejectors 51 apply a balanced ejection force to the counterweight unit 4. In some specific embodiments, four ejectors 51 are provided, and the end face of the counterweight unit 4 facing the ejectors 51 may be rectangular; the four ejectors 51 are located at the four corners of the counterweight unit 4, and the four ejectors 51 apply an ejection force to the four corners of the counterweight unit 4 to push the counterweight unit 4.

[0069] Referring to Figure 5 and Figure 6, in some further specific embodiments, the adjustment component 5 includes a power driving member 52 installed on the mounting frame 11. The driving end 521 of the power driving member 52 abuts against the counterweight unit 4 and is used to push the counterweight unit 4 to move relative to the mounting frame 11. The power driving member 52 may be connected to a power supply unit, and the power supply unit is used to provide power for the power driving member 52. Among them, one or more power driving members 52 may be respectively installed on each mounting frame 11. When one power driving member 52 is installed on each mounting frame 11, the power driving member 52 may be installed at the middle position of the mounting frame 11 or adjacent to the middle position of the mounting frame 11, so that the driving end 521 of the power driving member 52 can abut against the middle position of the counterweight unit 4 or abut against a position adjacent to the middle of the counterweight unit 4, thereby applying a relatively uniform driving force to the counterweight unit 4. When multiple power driving members 52 are installed on each mounting frame 11, the multiple power driving members 52 may be arranged at opposite ends of the mounting frame 11, so that the multiple power driving members 52 can abut against opposite ends of the counterweight unit 4, thereby applying a relatively uniform driving force to the counterweight unit 4. Specifically, each mounting frame 11 may be installed with two power driving members 52, and the two power driving members 52 are arranged at opposite ends of the mounting frame 11 along the height direction of the mounting frame 11, and the two power driving members 52 may be arranged at the middle position of the mounting frame 11 along the width direction of the mounting frame 11, or arranged adjacent to the middle position of the mounting frame 11 along the width direction of the mounting frame 11.. One or more power supply units may be provided, and one power supply unit may provide power for one power driving member 52, or one power supply unit may provide power for multiple power driving members 52 simultaneously. The power of the power driving member 52 can be provided by pneumatic, hydraulic, mechanical drive, etc. The corresponding power supply units are air pumps, hydraulic systems, motors, etc. The corresponding power driving members 52 can be cylinders, hydraulic cylinders, components that can convert the rotational motion of the motor into linear motion, such as screw rod structures. Preferably, the power driving member 52 is a hydraulic cylinder, the driving end 521 of the power driving member 52 may be the piston rod of the hydraulic cylinder, the power supply unit is a hydraulic system, and one power supply unit supplies power for multiple power driving members 52 simultaneously.

[0070] Refer to Figure 2, in some specific embodiments, a pair of adjustment components 5 may be provided. The pair of adjustment components 5 and the pair of counterweight units 4 are connected in one-to-one correspondence. When adjusting the positions of the pair of counterweight units 4, it is necessary to make the moving amounts of the pair of counterweight units 4 the same, so that the particle therapy device 100 is evenly stressed in the interval direction of the pair of support arms 12. To facilitate observing the moving amount of the counterweight unit 4, the mounting frame 11 is further provided with a scale 112, and at least a part of the scale 112 extends to be stacked with the counterweight unit 4. A plurality of scale lines are arranged at equal intervals along the moving direction of the counterweight unit 4 on the scale 112, so that the scale 112 can be used to indicate the moving amount of the counterweight unit 4. For example, when the counterweight unit 4 and the mounting frame 11 are in the initial position, the scale line corresponding to the indicating position of the counterweight unit 4 is observed and recorded as the initial scale line. After the counterweight unit 4 moves, the number of scale lines separated between the scale line corresponding to the indicating position of the counterweight unit 4 at this time and the initial scale line is observed. By adjusting the number of scale lines separated between the scale line corresponding to the indicating position of the pair of counterweight units 4 after moving and the initial scale line to be the same, the moving amounts of the pair of counterweight units 4 can be made the same. Among them, the indicating positions of the pair of counterweight units 4 are the same, and the indicating position of the counterweight unit 4 can be any part that is stacked with the scale 112 before and after the counterweight unit 4 moves. For example, the indicating positions of the pair of counterweight units 4 are both the end face positions of the counterweight unit 4 facing the mounting frame 11.

[0071] Referring to Figure 4 , in some specific embodiments, after adjusting the relative positions between the counterweight unit 4 and the mounting frame 11 to make the particle therapy device 100 in a balanced state, it is necessary to fix the counterweight unit 4 at this position. To fix the counterweight unit 4, the particle therapy device 100 may further be provided with a gasket 13 and a locking member 14. When relative displacement occurs between the counterweight unit 4 and the mounting frame 11, a gap will be generated between the counterweight unit 4 and the mounting frame 11. The gasket 13 can be disposed between the counterweight unit 4 and the mounting frame 11 to fill the gap between the counterweight unit 4 and the mounting frame 11, thereby compensating for the moving displacement of the counterweight unit 4 relative to the mounting frame 11. Then, the locking member 14 can be used to lock the counterweight unit 4 to the mounting frame 11. Among them, when the driving end 521 of the power driving member 52 extends into the mounting groove 41, the gasket 13 may be provided with an avoidance groove for avoiding the driving end 521 of the power driving member 52; when the locking member 14 extends into the mounting groove 41, the gasket 13 may be provided with an avoidance groove for avoiding the locking member 14, so that the gasket 13 will not interfere with the driving end 521 of the power driving member 52 and the locking member 14.

[0072] The locking member 14 can pass through the counterweight unit 4 and be threadedly connected to the mounting bracket 11 to fix the counterweight unit 4 to the mounting bracket 11. In addition, the rod portion of the locking member 14 for passing through the counterweight unit 4 can guide the movement of the counterweight unit 4, so that the counterweight unit 4 can move axially along the locking member 14 under the guidance of the locking member 14, and the axis of the locking member 14 can be parallel to the required movement direction of the counterweight unit 4. Among them, the locking member 14 can be a locking bolt, specifically a super bolt.

[0073] To facilitate the installation of the gasket 13, an installation groove 41 is provided at one end of the counterweight unit 4 facing the mounting bracket 11. The size of the installation groove 41 can be adapted to the size of the gasket 13. For example, the length of the installation groove 41 is slightly greater than the length of the gasket 13, and / or the width of the installation groove 41 is slightly greater than the width of the gasket 13. At least a part of the gasket 13 can be received in the installation groove 41, so that the gasket 13 can be guided by the wall forming the installation groove 41 to ensure the correct installation position of the gasket 13. Among them, the installation groove 41 and the gasket 13 can be provided at the middle position of the end face of the counterweight unit 4 facing the gasket 13.

[0074] In some specific embodiments, when the adjustment assembly 5 does not adjust the counterweight unit 4, the counterweight unit 4 can be in contact with the mounting bracket 11. At this time, the acting force at the end corresponding to the counterweight unit 4 in the lever structure can be less than the acting force at the end corresponding to the particle accelerator 3 in the lever structure. By separating the counterweight unit 4 from the mounting bracket 11, the particle therapy device 100 can be adjusted to a balanced state.

[0075] To facilitate the installation of the particle therapy device 100, the particle therapy device 100 further includes a support 300. The support 300 can be connected to the rotating assembly 2 and can be installed on the ground or on other fixing frames, so that the support 300 can support the rotating assembly 2 and the rotating frame 1 connected to the rotating assembly 2, and can also support components such as the particle accelerator 3, the counterweight unit 4, and the adjustment assembly 5 installed on the rotating frame 1. Among them, the direction of the supporting force of the support 300 can be towards the rotating shaft 21 of the rotating frame 1. Refer to Figure 7 , the present invention also provides a debugging system for a particle therapy device 100, including the above-mentioned particle therapy device 100 and a pair of lifting units 200.

[0076] One end of the hoisting unit 200 can be fixed above the particle therapy device 100. For example, the particle therapy device 100 is installed in a treatment room, one end of the hoisting unit 200 is fixed to the ceiling of the treatment room or a fixing frame connected to the ceiling, and the other end of the hoisting unit 200 is connected to the particle therapy device 100, specifically, it can be connected to the rotating gantry 1 of the particle therapy device 100. The connection positions of a pair of hoisting units 200 and the rotating gantry 1 are respectively located on opposite sides of the rotation axis 21 of the rotating gantry 1, and a pair of hoisting units 200 lift the particle therapy device 100 to a balanced state; that is, when the acting force at one end of the lever structure formed in the particle therapy device 100 is relatively large, the hoisting unit 200 connected to the same end as the lever structure applies a hoisting force to offset part of the acting force at the corresponding end of the lever structure, thereby enabling the lever structure to form a balanced state. Among them, the hoisting unit 200 can be a hoisting gourd, the hoisting unit 200 can be connected to the support arm 12 or the mounting bracket 11 in the rotating gantry 1, and a sling loop 202 is provided at the end of the hoisting unit 200 connected to the rotating gantry 1, and the hoisting unit 200 is connected to the rotating gantry 1 through the sling loop 202.

[0077] At least one of a pair of hoisting units 200 is provided with a mechanical sensor 201. For example, in the initial state of the particle therapy device 100, the hoisting unit 200 capable of applying a hoisting force to the particle therapy device 100 is provided with the mechanical sensor 201. Preferably, each hoisting unit 200 is provided with a mechanical sensor 201. Among them, the mechanical sensor 201 is used to detect the magnitude of the hoisting force applied by the hoisting unit 200 to the particle therapy device 100, and the mechanical sensor 201 can be connected to a controller so that the controller can receive the signal detected by the mechanical sensor 201 and display the numerical value of the hoisting force detected by the mechanical sensor 201 for the user to observe, and the user can make corresponding adjustments to the counterweight unit 4 according to the numerical value of the hoisting force.

[0078] The present invention also provides a debugging method for the particle therapy device 100, which is applied to the above-mentioned particle therapy device 100 debugging system. The debugging method for the particle therapy device 100 includes step S02 and step S03, and may also include step S01, step S04 and step S05.

[0079] Step S01: Assemble the particle therapy device 100 and make the locking member 14 not lock the counterweight unit 4, so that the counterweight unit 4 is in an unlocked state. At this time, the distance between the counterweight unit 4 and the rotation axis 21 of the rotating gantry 1 is adjustable.

[0080] Step S02: Connect a pair of hoisting units 200 to different corresponding positions on the rotating gantry 1 of the particle therapy device 100, and the corresponding positions are the aforementioned connection positions respectively located on opposite sides of the rotation axis 21 of the rotating gantry 1.

[0081] Step S03: Adjust the position of the counterweight unit 4 in the particle therapy device 100 so that the forces on both sides of the particle therapy device 100 on the two sides of the rotation axis 21 are balanced, and the particle therapy device 100 is in the balanced position.

[0082] Step S04: After the particle therapy device 100 is in the balanced position, use a spacer 13 to pad between the counterweight unit 4 and the mounting frame 11 to compensate for the movement amount of the counterweight unit 4.

[0083] Step S05: Use a locking member 14 to lock the counterweight unit 4 to the mounting frame 11, and separate a pair of lifting units 200 from the particle therapy device 100, thereby realizing the removal of the lifting units 200.

[0084] Step S01 specifically includes: providing a rotating gantry 1, installing the particle accelerator 3 and the counterweight unit 4 on opposite sides of the rotating gantry 1, connecting the support 300 to the rotating assembly 2, and installing the support 300 on the ground or on other fixed frames, and installing the adjustment assembly 5 on the mounting frame 11 and abutting against the counterweight unit 4.

[0085] In Step S02, after the particle therapy device 100 is assembled, first connect one lifting unit 200 to the end with a greater acting force in the lever structure formed by the particle therapy device 100, so that the lifting unit 200 exerts a lifting force on the particle therapy device 100 to make the particle therapy device 100 in or basically in the balanced state, and then connect the other lifting unit 200 to the other end of the lever structure formed by the particle therapy device 100. At this time, the particle therapy device 100 remains in the balanced state under the action of the lifting units 200.

[0086] In Step S03, adjusting the position of the counterweight unit 4 in the particle therapy device 100 specifically includes: reading the lifting force applied by the lifting unit 200 through the mechanical sensor 201. When only one lifting unit 200 is provided with the mechanical sensor 201, by adjusting the position of the counterweight unit 4, the lifting force detected by the mechanical sensor 201 gradually tends to 0. When the lifting force detected by the mechanical sensor 201 is 0, stop adjusting the position of the counterweight unit 4. At this time, the particle therapy device 100 is in the balanced state, and the lifting unit 200 does not exert a lifting force on the particle therapy device 100. When both lifting units 200 are provided with the mechanical sensor 201, adjust the position of the counterweight unit 4 so that the lifting forces applied by a pair of lifting units 200 are the same, that is, the lifting forces detected by a pair of mechanical sensors 201 in a pair of lifting units 200 are the same. At this time, the particle therapy device 100 is in the balanced position. Among them, the lifting forces detected by a pair of mechanical sensors 201 can specifically be both 0, that is, the lifting unit 200 does not exert a lifting force on the particle therapy device 100. As a preferred method, both lifting units 200 are provided with the mechanical sensor 201.

[0087] When the adjustment assembly 5 includes an ejector 51, the relative position of the ejector 51 and the mounting bracket 11 is adjusted to change the length of the end of the ejector 51 in contact with the counterweight unit 4 protruding from the mounting bracket 11, thereby controlling the distance that the counterweight unit 4 moves under the ejection action of the ejector 51. When the adjustment assembly 5 includes a power driving member 52, the power supply unit supplies power to the power driving member 52 so that the driving end 521 of the power driving member 52 moves and ejects the counterweight unit 4.

[0088] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Without departing from the principle and purpose of the present invention, those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the invention, and all such changes should fall within the protection scope of the claims of the present invention.
