Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical devices, and in particular to a supporting device of radiotherapy equipment and a radiotherapy system. Background Art
[0002] Tumor is a common and frequently occurring disease, and radiotherapy is a common method of treating tumors.
[0003] Related technology radiotherapy equipment (referred to as radiotherapy equipment), such as Figure 1 As shown, it includes a fixed gantry 1, a rotating gantry 2, a radiation head 3 and a treatment bed 4, wherein the rotating gantry 2 includes a support arm 21, and the radiation head 3 is arranged on the support arm 21, and can emit a radiation beam; the fixed gantry 1 is fixedly arranged on the ground and connected to the rotating gantry 2, so that the radiation head 3 is driven to rotate along the rotation axis 5 of the radiotherapy device through the support arm 21. The intersection of the center of the radiation beam and the rotation axis 5 is the "isocenter 6", and the patient is located on the treatment bed 4, and the tumor is aligned with the isocenter 6 to achieve radiotherapy of the tumor.
[0004] like Figure 2 As shown, due to the weight of the radiation head 3 and the excessive size of the overhanging arm, the radiation head of the radiotherapy equipment sags to varying degrees during use, resulting in an unintentional shift of the isocenter 6 (the actual isocenter after sagging is 6' or 6"), with a shift distance of d. Especially in the case of circular rotation of the radiation head 3, as shown by the dotted line, when the radiation head 3 rotates to the bottom, the isocenter 6" shifts to the other direction, that is, the error accuracy is reduced exponentially. When the isocenter shifts, the radiation beam emitted by the radiation head not only fails to irradiate the tumor and has no therapeutic effect, but the radiation beam emitted by the radiation head irradiates normal tissues or organs of the human body, generates additional radiation, and may also induce secondary tumors.

[0045] Figure 3 A structural diagram of a radiotherapy system provided by an embodiment of the present invention is shown in FIG. Figure 3 As shown, the radiotherapy system includes: a radiotherapy device 10 and a support device 20 for the radiotherapy device 10. The radiotherapy device 10 includes a support arm 101 and a radiation head 102. The radiation head 102 is arranged at one end of the support arm 101, and the support arm 101 can drive the radiation head 102 to rotate; the support device 20 is used to support the radiotherapy device 10, such as Figure 4 As shown, the support device 20 includes a support portion 201 and a rotating portion 202, the support portion 201 is movably connected to the rotating portion 202, the rotating portion 202 is connected to the portion to be connected of the radiotherapy device 10, and can rotate synchronously with the support arm 101 of the radiotherapy device 10. Here, the portion to be connected of the radiotherapy device 10 includes: the support arm 101.
[0046] It should be noted that the part to be connected of the radiotherapy device 10 may include a radiation head 102, the support arm 101 and the radiation head 102 in addition to the support arm 101. Figure 3 As shown in connection with the support arm 101, it is also possible to Figure 4 Connected to the radiation head 102 as shown, or as Figure 5 As shown, the support arm 101 and the radiation head 102 are connected simultaneously.
[0047] It should be noted here that the supporting device 20 may be one or more.
[0048] In the radiotherapy system provided by an embodiment of the present invention, the supporting portion of the supporting device is connected to the radiotherapy equipment through a rotating portion movably connected thereto. Even when the rotating portion rotates synchronously with the radiotherapy equipment, the support arm and / or the radiation head of the radiotherapy equipment can be effectively supported, thereby avoiding the isocenter deviation problem caused by the drooping of the radiation head of the radiotherapy equipment.
[0049] In the embodiment of the present invention, the support arm 101 of the radiotherapy device 10 has only one arm. Of course, the support arm 101 of the radiotherapy device 10 may include multiple arms, such as Figure 6 As shown, the arm 101 includes a first arm 1011 and a second arm 1012, wherein the first arm 1011 is connected to the radiation head 102; the second arm 1012 is connected to a detector or a counterweight arranged opposite to the radiation head 102; accordingly, the part to be connected of the radiotherapy device 10 may include: the first arm 1011 and / or the second arm 1012; or the radiation head 102 and / or the detector; or the radiation head 102 and / or the counterweight. That is to say, the rotating part 202 can be connected to only the first arm 1011, the second arm 1012, the radiation head 102 or the detector. Of course, the rotating part 202 can also be connected to two oppositely arranged parts of the above-mentioned parts to be connected (for example, the first arm 1011 and the second arm 1012, or the radiation head 102 and the detector, or the radiation head 102 and the counterweight) at the same time.
[0050] In the case where the part to be connected includes two parts arranged opposite to each other, the rotating part 202 may be one or more. For example, the rotating part 202 includes: a first rotating part 202' and a second rotating part 202", which are respectively connected to the corresponding parts. For example, Figure 6 As shown, in the case where the part to be connected includes the first arm 1011 and the second arm 1012, the first rotating part 202' is connected to the first arm 1011, and the second rotating part 202" is fixedly connected to the second arm 1012; similarly, in the case where the part to be connected includes the radiation head 102 and the detector, the first rotating part 202' is connected to the radiation head, and the second rotating part 202" is connected to the detector; in the case where the part to be connected includes the radiation head 102 and the counterweight, the first rotating part 202' is connected to the radiation head 102, and the second rotating part 202" is connected to the counterweight.
[0051] In the embodiment of the present invention, Figures 3 to 6 As shown, the support device 20 for supporting the radiotherapy device 10 is arranged on the reference surface. Figure 7As shown, the support device 20 can also be arranged on the treatment bed 104 of the radiotherapy equipment 10. Further, the support device 20 is arranged on the treatment bed base 1041 of the treatment bed 104. Here, the treatment bed base 1041 is located on the reference plane and is used to support the bed plate 1042. The bed plate 1042 can move in different directions relative to the treatment bed base 1041.
[0052] In the embodiment of the present invention, Figures 3 to 7 As shown, the arm 101 of the radiotherapy device 10 (including the first arm 1011 and the second arm 1012) can rotate around the rotation axis 103, and accordingly, the rotating part 202 (including the first rotating part 202' and the second rotating part 202") can rotate around the central axis 203. When the rotating part 202 rotates synchronously with the arm 101 of the radiotherapy device 10, the central axis 203 of the rotating part 202 coincides with the rotation axis 103 of the arm 101 of the radiotherapy device 10, that is, the central axis 203 and the rotation axis 103 are located on the same straight line. In this way, the rotation of the arm 101 of the radiotherapy device 10 is smoother.
[0053] The specific structure of the supporting device 20 will be described in detail through the following embodiments.
[0054] In the first embodiment, if Figure 8 As shown, the support portion 201 of the support device 20 includes: a circular opening 2011a, which is used for the rotating portion 202 to move along the circular opening 2011a. The circular opening 2011a allows the part to be connected (such as the support arm 101) to pass through, and can also allow the bed plate 1042 of the treatment bed 104 of the radiotherapy device 10 to enter and exit, and can also allow the bed plate 1042 of the treatment bed 104 of the radiotherapy device 10 to enter and exit and the part to be connected (such as the support arm 101) to pass through at the same time.
[0055] like Figure 8 As shown, the rotating part 202 can rotate around the central axis 203 of the rotating part 202 along the circular opening 2011a, and the center point of the circular opening 2011a is located on the central axis 203. When the part to be connected moves around the rotating axis 103, the rotating part 202 connected thereto can be driven to move around the central axis 203 (or the rotating axis 103) along the circular opening 2011a.
[0056] Furthermore, the supporting portion 201 also includes: an arcuate guide rail 2012a, which is arranged on the circular opening 2011a; correspondingly, the rotating portion 202 includes: a sliding member 2021a, which is fixedly connected to the part to be connected (such as the support arm 101) and movably connected to the arcuate guide rail 2012a, and is used to drive the part to be connected (such as the support arm 101) to move along the arcuate guide rail 2012a.
[0057] Here, the arc guide rail 2012a can be set as an unclosed guide rail with a preset curvature, or can be set as a closed annular guide rail.
[0058] It should be noted that the arcuate guide rail 2012a may be a guide rail provided on the support portion 201 or a separately provided guide rail. Here, the arcuate guide rail 2012a may be a guide groove or a guide ridge, and the embodiment of the present invention does not specifically limit this.
[0059] In order to cooperate and connect different types of parts to be connected with the sliding member 2021a, the rotating part 202 further includes: a connecting adapter 2022a, which is used to connect the part to be connected (such as the support arm 101) with the sliding member 2021a.
[0060] In the second embodiment, if Fig. 9 As shown, the support portion 201 of the support device 20 includes: a guide member 2011b, the outer contour of the guide member 2011b is an arc shape, and the outer contour of the guide member 2011b is movably connected to the rotating portion 202 for allowing the part to be connected (such as the support arm 101) to move along the outer contour of the guide member 2011b.
[0061] It should be noted here that the inner contour of the rotating part 202 can move along the outer contour of the guide member 2011b, and the outer contour of the rotating part 202 is not limited to a shape, such as a circle, rectangle, five-pointed star, pentagon, hexagon or other irregular shapes, such as a four-leaf clover.
[0062] It should also be noted that the movable connection methods between the rotating part 202 and the guide member 2011b include but are not limited to guide rail connection, roller bearing connection, etc.
[0063] Further, such as Fig. 9 As shown, the rotating part 202 includes a circular opening 2021b, and the rotating part 202 is sleeved on the outer contour of the guide member 2011b through the circular opening 2021b. In this way, when the rotating part 202 rotates around the outer contour of the guide member 2011b, the part to be connected (such as the support arm 101) fixedly connected to the rotating part 202 can be driven to move synchronously.
[0064] Here, the arc-shaped outer contour of the guide member 2011b can be an unclosed preset arc or a closed circle.
[0065] like Fig. 9 As shown, the guide member 2011b includes: an accommodating opening 20111b, which can allow the part to be connected (such as the support arm 101) to pass through, and can also allow the bed board 1042 of the treatment bed 104 of the radiotherapy equipment 10 to enter and exit, and can also allow the bed board 1042 of the treatment bed 104 of the radiotherapy equipment 10 to enter and exit and the part to be connected (such as the support arm 101) to pass through at the same time.
[0066] It should be noted here that the accommodating opening 20111b can be circular, square or other shapes, so that the treatment bed 104 can enter and exit and / or the part to be connected can pass through.
[0067] Further, such as Fig. 9 As shown, the support portion 201 further includes: a support frame 2012b, the support frame 2012b is connected to the guide member 2011b, and is used to support the guide member 2011b.
[0068] In the above-mentioned first embodiment and second embodiment, the structures and connection methods of the rotating part 202 and the supporting part 201 of the supporting device 20 are different, but they respectively include a circular opening 2011a and a receiving opening 20111b, and the layout of the circular opening 2011a and the receiving opening 20111b are similar, that is, the part to be connected passes through the circular opening 2011a (or the receiving opening 20111b) or the part to be connected does not pass through the circular opening 2011a (or the receiving opening 20111b).
[0069] The following is an explanation of the layout of the support device 20 and the radiotherapy equipment 10 in two cases.
[0070] The first situation: the part to be connected passes through the circular opening 2011a (or the receiving opening 20111b).
[0071] Taking the supporting device 20 in the first embodiment as an example, in one use mode, Figure 3 As shown, the support device 20 is placed on the reference surface, and the support arm 101 passes through the circular opening 2011a of the support device 20, and the rotating part 202 is connected to the support arm 101 of the radiotherapy device 10; in another use mode, as shown in FIG. Figure 4 As shown, the support device 20 is set on the reference surface, the radiation head 102 passes through the circular opening 2011a of the support device 20, and the rotating part 202 is connected to the radiation head 102 of the radiotherapy device 10; in another use mode, as Figure 7 As shown, the support device 20 is set on the treatment bed 104 (for example, the treatment bed base 1041), and the radiation head 102 passes through the circular opening 2011a of the support device 20, and the rotating part 202 is connected to the radiation head 102 of the radiotherapy device 10. Of course, there are other usage methods, which are not listed one by one.
[0072] In the first case, the parts to be connected pass through the circular opening (or receiving opening) of the supporting device, and can drive the rotating part to move along the circular opening (or receiving opening). This will cause the supporting device to be larger in size, which is not conducive to the installation of the supporting device in the treatment room where the radiotherapy equipment is located.
[0073] The second situation: the part to be connected does not pass through the circular opening 2011a (or the receiving opening 20111b).
[0074] The portion to be connected is arranged not to pass through the circular opening 2011 a (or the accommodating opening 20111 b ) to reduce the volume of the supporting device 20 .
[0075] Taking the supporting device 20 in the second embodiment as an example, in one use mode, Fig.10 As shown, the support device 20 is arranged on the reference surface below the support arm 101, and the rotating part 202 is connected to the support arm 101 of the radiotherapy device 10; in another use mode, as Fig.11 As shown, the support device 20 is arranged on the reference surface below the support arm 101, and the rotating part 202 is connected to the radiation head 102 of the radiotherapy device 10. Of course, there are other usages, which will not be listed one by one.
[0076] In the above example of the second case, the support device 20 is arranged on the reference surface below the support arm 101. When the part to be connected drives the rotating part 202 to rotate around the rotating axis 203 to a position close to the reference surface, the support part 201 will block the movement of the part to be connected, resulting in motion interference. Fig.12 As shown, the support device 20 is arranged on the treatment bed 104 (treatment bed base 1041), and the rotating part 202 is connected to the radiation head 102. In this way, in the absence of motion interference, the volume of the support device is reduced, and the installation of the support device is facilitated.
[0077] Regarding the structure of the supporting device 20 , in one embodiment, it may further include: a driving portion (not shown in the figure), which is connected to the rotating portion 202 and is used to drive the rotating portion 202 to move synchronously with the support arm 101 .
[0078] In another embodiment, if Fig.13 As shown, the supporting device 20 may further include: an imaging device 204 disposed on the rotating portion 202. Of course, the imaging device 204 may also be disposed on the supporting portion 201.
[0079] It should be noted that the imaging device 204 includes: a tube 2041 and detectors 2042 arranged opposite to each other. The number of the tube 2041 and the detectors 2042 arranged opposite to each other can be one group or multiple groups.
[0080] In another embodiment, if Fig.13 As shown, the supporting device 20 further includes: a flat panel detector 205 , which is disposed on the rotating portion 202 at a position opposite to the radiation head 102 of the radiotherapy device 10 , and is used to verify the dose of the beam emitted by the radiation head 102 .
[0081] The above description is only an implementation mode of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
