Description

Technical Field

[0001] The present application relates to the technical field of medical equipment, and in particular to a shared bed moving device and a diagnosis and treatment system. Background Art

[0002] In related technologies, arranging the CT imaging system and the radiotherapy system together in the same radiotherapy treatment room can greatly shorten the time and energy consumed by patients in running around different departments and equipment areas, making the diagnosis and treatment process more compact and efficient. Patients do not need to wait for a long time for transfer, and can quickly complete the continuous operations from precise positioning of image scanning to implementation of radiotherapy in the same space, which reduces the physical and mental burden while also reducing the medical risks that may arise during transfer.

[0003] However, in terms of equipment settings, integrating the imaging device and the radiotherapy device into one will cause strong mutual interference between the two, resulting in poor imaging quality and greatly reduced radiotherapy effects.

[0004] Therefore, it is necessary to find a balance in equipment layout and patient position fixation, to eliminate interference between devices and to ensure the stability of the patient's position, so as to achieve accurate and effective radiotherapy, improve the success rate of tumor treatment, reduce treatment errors caused by changes in equipment layout and position, and provide patients with better medical services. Summary of the invention

[0005] The purpose of the present application is to provide a shared bed moving device and a diagnosis and treatment system, aiming to solve the problem that changes in the patient's body position during the diagnosis and treatment process may affect the treatment effect.

[0006] In order to achieve the above objectives, this application adopts the following technical solutions:

[0007] In a first aspect, the present application provides a shared bed moving device, which includes a first supporting device, a second supporting device and a shared bed bed board, wherein the first supporting device includes a first supporting base and a driving platform, the driving platform can be slidably disposed on the first supporting base, the second supporting device includes a second supporting base and a receiving platform, the receiving platform can be slidably disposed on the second supporting base, and the shared bed bed board includes a shared bed bed board, which is transmission-connected to the driving platform or the receiving platform.

[0008] The driving platform is used to drive the common bed bed board to move along the first coordinate axis, so as to detach the common bed bed board from the driving platform and transfer it to the receiving platform, and the receiving platform is used to receive the common bed bed board and drive the common bed bed board to move; and / or, when the common bed bed board is detached from the driving platform, the driving platform is also used to dock with the common bed bed board and drive the common bed bed board to move along the first coordinate axis, so as to transfer the common bed bed board from the receiving platform to the driving platform.

[0009] During diagnosis and treatment, it is sometimes necessary to change the patient's position, such as moving from one functional area to another for different stages of diagnosis and treatment. The shared bed moving device in the present application is designed such that the driving platform of the first support device can be slidably arranged on the first support base, and the receiving platform of the second support device can be slidably arranged on the second support base, so that the shared bed board can be transferred between the driving platform and the receiving platform.

[0010] The driving platform can drive the shared bed board to move along the first coordinate axis (the first coordinate axis can be the direction from the driving platform to the receiving platform), and can realize the shared bed board detaching from the driving platform and transferring to the receiving platform, or after the shared bed is detached from the driving platform, the driving platform can also dock with the shared bed board and drive it to move in the opposite direction from the driving platform to the receiving platform, so that the shared bed board is transferred from the receiving platform back to the driving platform. The whole process is a controlled and supported smooth movement and transfer, which avoids unnecessary changes in the patient's position due to random moving and shaking during the transfer of patients, thereby ensuring that the patient's position is relatively stable when switching between various links of diagnosis and treatment, and reducing the adverse effects of changes in body position on the treatment effect.

[0011] The shared bed board includes a shared bed board, which is connected to the driving platform or the receiving platform. This means that the patient always lies on the shared bed board, and when transferring between different supporting devices (the first supporting device and the second supporting device), the body still relies on the same bed board, and there is no situation where the body position is disrupted and needs to be readjusted due to switching from one independent support to another, thereby maintaining the continuity of the patient's body position, ensuring to the greatest extent that the body position is relatively fixed throughout the diagnosis and treatment process, which helps to improve the treatment effect and reduce interference factors caused by changes in body position.

[0012] In some embodiments, the first support device also includes a first lead screw and a first drive assembly, the first lead screw is disposed on the first support base, and the first lead screw is transmission-connected to the drive platform; the first drive assembly is disposed on the first support base, and the first drive assembly is transmission-connected to the first lead screw, and the first drive assembly is used to drive the first lead screw to rotate so that the drive platform moves along the first coordinate axis relative to the first support base.

[0019] In some embodiments, the driving platform also includes a push block, which is connected to the second lead screw. When the second lead screw rotates to drive the common bed board to move along the first coordinate axis relative to the driving platform body, it also drives the push block to move along the first coordinate axis. After the common bed board is disengaged from the driving platform, the second lead screw continues to rotate and drives the push block to continue to move along the first coordinate axis to push the common bed board to move to the target position along the receiving platform.

[0020] In some embodiments, the second supporting device also includes a mating part and a locking part. The mating part is arranged on the bed board of the common bed, and the locking part is arranged on the receiving platform. When the bed board of the common bed moves to the target position of the receiving platform, the locking part locks the mating part to fix the bed board of the common bed at the target position.

[0021] In some embodiments, the locking member is an electromagnetic locking device.

[0043] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] The term "and / or" in this article is only a description of the association relationship of associated objects, indicating that three relationships may exist. For example, and / or can represent the three situations of existing alone, existing at the same time, and existing alone.

[0045] The terms "first" and "second" and the like in the specification and drawings of this application are used to distinguish different objects, or to distinguish different processing of the same object, rather than to describe a specific order of objects.

[0046] In addition, the terms "including" and "having" and any variations thereof mentioned in the description of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but may optionally include other steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.

[0047] It should be noted that, in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0048] In the description of the present application, unless otherwise specified, “plurality” means two or more.

[0049] In the current tumor radiotherapy process, patients often need to be transferred back and forth between different diagnostic and treatment equipment so that they can be sent to the corresponding diagnostic and treatment areas of each diagnostic and treatment equipment to receive corresponding imaging and treatment. For example, in the tumor radiotherapy process, imaging equipment is generally used to perform imaging operations on patients first, and through this operation, key information such as the specific location, size, and morphology of the tumor is obtained, and then the corresponding treatment plan is formulated based on this information obtained by the imaging equipment. Next, the patient must be transferred to the location of the radiotherapy equipment, and the radiotherapy equipment must be controlled to carry out radiotherapy on the tumor according to the established treatment plan.

[0050] In the past, in order to optimize the space and save the space occupied by the imaging device and the radiotherapy device, the imaging device and the radiotherapy device are often integrated into one device. However, there will be a large mutual interference between the imaging device and the radiotherapy device inside the integrated device, which ultimately leads to low imaging quality and unsatisfactory radiotherapy effect.

[0051] If the imaging equipment and radiotherapy equipment are set up separately, the mutual interference between them can be eliminated or reduced, thereby improving the quality of imaging and the effect of radiotherapy. However, the problem is that when the patient is transferred between multiple diagnostic and treatment equipment, the patient's position is easy to change, so the position of the diagnostic and treatment equipment will deviate, which will ultimately reduce the treatment effect.

[0052] In order to solve the above technical problems, in some embodiments, see Figure 1 The present application provides a shared bed moving device, which includes a first supporting device 100 ( Figure 1 The first supporting device 100 includes a first supporting base 101 and a driving platform 102 , and the driving platform 102 is slidably disposed on the first supporting base 101 .

[0053] See also Figure 2 The shared bed moving device also includes a second supporting device 200 , and the second supporting device 200 includes a second supporting base 201 and a receiving platform 202 , and the receiving platform 202 can be slidably disposed on the second supporting base 201 .

[0054] See also Figure 1 The shared bed moving device also includes a shared bed bed board 300, which is transmission-connected to the driving platform 102 or the receiving platform 202, and the shared bed bed board 300 is used to carry the patient.

[0055] Understandably, see Figure 1 Combined with Figure 2 The shared bed board 300 can have two placement positions. When the shared bed board 300 needs to be located on the first supporting device 100, the shared bed board 300 is transmission connected to the driving platform 102. When the shared bed board 300 needs to be located on the second supporting device 200, the shared bed board 300 is transmission connected to the receiving platform 202.

[0056] The driving platform 102 and the receiving platform 202 can drive the common bed board 300 to move, so that the common bed board 300 can move between the first supporting device 100 and the second supporting device 200, so that the common bed board 300 drives the patient to move between two positions.

[0057] Below, for the sake of convenience of explanation, a three-dimensional orthogonal coordinate system with an X-axis, a Y-axis, and a Z-axis is set, namely, the IEC EC61217 coordinate system, wherein the X-axis, the Y-axis, and the Z-axis are perpendicular to each other; the X-axis is the left-right direction, with the right direction being positive; the Y-axis is the front-back direction, with the front direction being positive; and the Z-axis is the up-down direction (direction of gravity), with the upward direction being positive.

[0058] In some embodiments, the driving platform 102 is used to drive the shared bed board 300 to move along the first coordinate axis to detach the shared bed board 300 from the driving platform 102 and transfer it to the receiving platform 202. The receiving platform 202 is used to receive the shared bed board 300 and drive the shared bed board 300 to move.

[0059] Exemplarily, the first coordinate axis is the Y-axis shown in the figure, and the first coordinate axis includes the positive direction of the Y-axis (i.e., the direction from the receiving platform 202 to the driving platform 102) and the negative direction of the Y-axis (i.e., the direction from the driving platform 102 to the receiving platform 202). Of course, the first coordinate axis can also be other directions. The Y-axis shown in this application is only used as an exemplary illustration and does not constitute a limitation on this application.

[0060] Understandably, see Figure 1 Combined with Figure 2 The driving platform 102 is used to drive the shared bed board 300 to move along the first coordinate axis, which means that the shared bed board 300 can move along the positive direction and the negative direction of the Y-axis under the driving action of the driving platform 102. In the case shown in the present application, when the driving platform 102 drives the shared bed board 300 to move along the positive direction of the Y-axis, the driving platform 102 drives the shared bed board 300 to move along the Y-axis toward the receiving platform 202.

[0061] During the process of the driving platform 102 driving the shared bed board 300 to move, along the positive direction of the Y-axis, the rear end of the shared bed board 300 gradually separates from the driving platform 102, and the receiving platform 202 can receive the part of the shared bed board 300 that is separated from the driving platform 102. When the shared bed board 300 is completely separated from the driving platform 102, the receiving platform 202 continues to drive the shared bed board 300 to move further.

[0062] In other embodiments, see Figure 1 When the shared bed board 300 is separated from the driving platform 102, the driving platform 102 is used to dock with the shared bed board 300 and drive the shared bed board 300 to move along the first coordinate axis, so that the shared bed board 300 is transferred from the receiving platform 202 to the driving platform 102. It should be noted that, taking the first coordinate axis as the Y axis as an example, at this time, the shared bed board 300 moves along the negative direction of the Y axis.

[0063] In other words, the driving platform 102 can move the common bed board 300 to the receiving platform 202 along the positive direction of the Y-axis, and can also transfer the common bed board 300 to the driving platform 102 along the negative direction of the Y-axis. The driving platform 102 can realize bidirectional driving of the common bed board 300.

[0064] In other embodiments, during the movement of the above-mentioned common bed bed board 300, when the common bed bed board 300 is detached from the driving platform 102 or needs to be docked with the driving platform 102, the receiving platform 202 is located at the initial position on the second support base 201 along the Y-axis direction. In this way, the common bed bed board 300 is detached from and docked with the driving platform 102 at the same position, eliminating the uncertainty caused by position changes and greatly improving the success rate of docking.

[0065] In other embodiments, see Figure 2 Combined with Figure 3 When the shared bed board 300 is separated from the driving platform 102, the receiving platform 202 receives the shared bed board 300, and the receiving platform 202 drives the shared bed board 300 to move by sliding on the second supporting base 201. For example, the receiving platform 202 can drive the shared bed board 300 to move to the target position along the positive direction of the Y-axis, and the receiving platform 202 can drive the shared bed board 300 to move to the position docking with the driving platform 102 along the negative direction of the Y-axis.

[0066] Of course, the receiving platform 202 can also drive the shared bed board 300 to move in other directions. The direction in which the receiving platform 202 drives the shared bed board 300 to move can be the same as the direction in which the driving platform 102 drives the shared bed to move, or it can be different. The present application does not limit this. The present application is an exemplary explanation based on the fact that the direction in which the receiving platform 202 drives the shared bed board 300 to move is the same as the direction in which the driving platform 102 drives the shared bed to move.

[0067] It can be understood that when a patient needs to be transferred between different devices, such as between the first support device 100 and the second support device 200, the driving platform 102 and the receiving platform 202 can accurately drive the common bed board 300 to move along the positive and negative directions of the Y-axis, thereby ensuring the consistency and stability of the patient's overall position during the transfer process.

[0068] Based on the above technical means, driven by the driving platform 102 and the receiving platform 202, the shared bed board 300 can be transferred to different positions in sequence, and can also return to the initial position, that is, the driving platform 102 can not only drive the shared bed board 300 to move, but also realize the separation from the shared bed board 300 and docking with the receiving platform 202. During the transfer process, the driving platform 102 accurately transfers the shared bed board 300 to the receiving platform 202, and the receiving platform 202 drives it to move. This stable handover process effectively avoids the shaking or change of the patient's position caused by improper handover. When the patient needs to be transferred back after the treatment, the driving platform 102 can accurately dock with the shared bed board 300 and move in the opposite direction, and transfer the shared bed board 300 from the receiving platform 202 back to the drive. During the whole process, the patient does not need to move by himself, which ensures the stability of the patient's position and further reduces the risk of position change due to transfer.

[0069] First, the present application exemplarily illustrates the specific structure of the first supporting device 100 .

[0070] In some embodiments, see Figure 1 Combined with Figure 3 The first supporting device 100 in the present application further includes a first lead screw 103 , which is disposed on the first supporting base 101 , and is transmission-connected to the driving platform 102 .

[0071] The first supporting device 100 also includes a first driving assembly 104, which is disposed on the first supporting base 101. The first driving assembly 104 is transmission-connected to the first lead screw 103, and the first driving assembly 104 is used to drive the first lead screw 103 to rotate so that the driving platform 102 moves along the first coordinate axis relative to the first supporting base 101, that is, the first driving assembly 104 is used to drive the first lead screw 103 to rotate so that the driving platform 102 moves along the positive direction and the negative direction of the Y-axis relative to the first supporting base 101.

[0072] It can be understood that the first lead screw 103 can rotate clockwise or counterclockwise. The rotation direction of the first lead screw 103 is different, and the movement direction of the drive platform 102 is also different. For ease of understanding, this application uses the clockwise rotation of the first lead screw 103 to drive the drive platform 102 to move along the positive direction of the Y-axis as an example. At the same time, when the first lead screw 103 rotates counterclockwise, the first lead screw 103 can drive the drive platform 102 to move along the negative direction of the Y-axis.

[0073] Of course, when the first lead screw 103 rotates clockwise, the first lead screw 103 can drive the driving platform 102 to move along the negative direction of the Y axis. At this time, when the first lead screw 103 rotates counterclockwise, the first lead screw 103 can drive the driving platform 102 to move along the positive direction of the Y axis. This application does not limit this, but only provides an exemplary description.

[0074] When the patient has completed the preparation work on the shared bed board 300 and is ready to move, the relative position between the drive platform 102 and the shared bed board 300 remains unchanged, and the first drive component 104 is started. The first drive component 104 drives the first screw 103 to rotate clockwise, and the drive platform 102 moves relative to the first support base 101 along the positive direction of the Y-axis. At this time, the drive platform 102 drives the shared bed board 300 to move along the positive direction of the Y-axis. Controlling the number of rotations of the first screw 103 can control the specific position of the drive platform 102. When the drive platform 102 moves to the rear end of the first screw 103 along the positive direction of the Y-axis, the first drive component 104 stops driving the first screw 103, and the first screw 103 stops rotating to fix the drive platform 102 and the shared bed board 300 at the first target position.

[0075] The first target position may be a first working position corresponding to the patient during the diagnosis and treatment process. Exemplarily, the first target position may be a diagnostic position corresponding to the patient during the diagnosis and treatment process.

[0076] At the same time, the first drive assembly 104 drives the first screw 103 to rotate counterclockwise, so that the first screw 103 drives the drive platform 102 to move the shared bed board 300 to the initial position. In this way, the patient can return to the original position when the diagnosis and treatment is finished, further improving the patient's medical experience.

[0077] In addition, since the screw drive has a high transmission accuracy, the present application can realize the precise movement of the shared bed board 300 by converting the rotational motion of the first screw 103 into the linear motion of the shared bed board 300 driven by the driving platform 102. Thus, the accuracy of the patient's position during the diagnosis and treatment process can be ensured, and the accuracy of the diagnosis and treatment effect can be ensured.

[0078] In some embodiments, the first screw 103 in the present application may be a ball screw.

[0079] The ball screw is mainly composed of a screw shaft, a nut, a reverse device and a ball. The screw shaft usually has a spiral groove, and the nut also has a corresponding groove inside. The ball is located between these grooves to form a rolling contact. The reverse device is used to guide the ball to circulate between the screw and the nut, so that the ball can continuously participate in the transmission process.

[0080] In the present application, the screw shaft is connected to the first drive assembly 104 in transmission, and the first drive assembly 104 drives the screw shaft to rotate. Due to the friction between the ball and the screw shaft and the nut groove and the rolling characteristics of the ball, the ball rolls in the groove and drives the nut to move linearly along the axis of the screw shaft. In this process, the ball plays a role similar to that of a rolling element in a bearing, converting the rotary motion of the screw shaft into the linear motion of the nut, that is, when the screw shaft rotates, the nut can move along the positive or negative direction of the Y axis.

[0081] In other embodiments, the nut in the ball screw is used to transmit power to the driving platform 102, so that the driving platform 102 can move along the positive direction or the negative direction of the Y-axis.

[0082] Exemplarily, the end surface of the nut in the ball screw facing the drive platform 102 along the positive direction of the Y-axis can contact the end surface of the drive platform 102 facing the nut along the negative direction of the Y-axis, so that the nut can push the drive platform 102 to move along the positive direction or negative direction of the Y-axis.

[0083] In some embodiments, see Figure 1 Combined with Figure 3 The first support base 101 in the present application includes a first support front body 1011, and the first support front body 1011 is provided with a first slide rail 1012 arranged along the Y-axis direction. The driving platform 102 is slidably connected to the first slide rail 1012, and the first slide rail 1012 plays a good guiding and supporting role for the driving platform 102. In the process of the first lead screw 103 driving the driving platform 102 to move, the first slide rail 1012 bears part of the supporting force of the driving platform 102 in the Y-axis direction, and shares the load pressure borne by the first lead screw 103.

[0084] In some embodiments, see Figure 1 Combined with Figure 4 Along the horizontal direction of the X-axis in the figure, the front body 1011 before the first support is provided with a first slide rail A1012a and a first slide rail B1012b. The first slide rail A1012a and the first slide rail B1012b are slidably connected to the two sides of the driving platform 102 to provide double-sided guidance and support for the driving platform 102 during the sliding process on the front body 1011 before the first support, thereby further enhancing the stability of the driving platform 102 during the sliding process.

[0085] When the driving platform 102 moves, even if there are certain slight vibrations or uneven force conditions during the transmission of the first screw 103, the first slide rail A1012a and the first slide rail B1012b can ensure that the driving platform 102 slides smoothly along the predetermined track, reducing unstable phenomena such as shaking and bumping, so that the movement process of the driving platform 102 is more stable and smooth.

[0086] In some embodiments, a first accommodating groove is provided in the front body 1011 of the first support, the driving platform 102 and the first lead screw 103 are accommodated in the first accommodating groove, and the first lead screw 103 can rotate in the first accommodating groove, and the first slide rail A1012a and the first slide rail B1012b are arranged at the bottom of the first accommodating groove, so that the driving platform 102 can slide in the first accommodating groove along the first slide rail A1012a and the first slide rail B1012b.

[0087] On the one hand, by accommodating the driving platform 102 and the first lead screw 103 in the first accommodating groove, the layout of the first supporting device 100 is made more compact.

[0088] On the other hand, the first accommodating groove provides a physical protective barrier for the drive platform 102 and the first lead screw 103, which can prevent accidental collision and contact of these key components by external objects, and reduce the risk of damage caused by external interference. Since the drive platform 102 and the first lead screw 103 are confined in the first accommodating groove, their relative positions during operation are more stable. When the first lead screw 103 rotates in the first accommodating groove, its own axial reciprocating motion and the movement of the drive platform 102 along the lead screw can be carried out in an orderly manner in the relatively closed and regular space of the first accommodating groove, reducing the shaking, offset and other situations caused by external uncertain factors, and further ensuring the accuracy and stability of the movement of the drive platform 102.

[0089] In the above process, it can be understood that, see Figure 4 , the driving platform 102 only drives or drives the shared bed board 300 to move along the Y axis. Along the horizontal direction where the X axis is located in the figure, it can be seen that the width of the driving platform 102 is smaller than the width of the shared bed board 300. On the one hand, the reduction in the size of the driving platform 102 is useful for improving the space utilization rate of the entire shared bed moving device. On the other hand, the smaller width of the driving platform 102 than the width of the shared bed board 300 is helpful for optimizing the center of gravity distribution of the shared bed board 300. Since the driving platform 102 usually bears a large power transmission and load pressure, the driving platform 102 is designed to be relatively narrow, so that the center of gravity of the driving platform 102 and the shared bed board 300 as a whole can be closer to the central axis of the first supporting device 100, and the driving platform 102 and the shared bed board 300 can form a more stable mechanical structure, which improves the overall stability of the driving platform 102 and the shared bed board 300 during use and reduces the risk of shaking or tilting due to the shift of the center of gravity.

[0090] In some embodiments, see Figure 3 The driving platform 102 includes a driving platform body 1021 . Correspondingly, the driving platform body 1021 is slidably connected to the first supporting base 101 (eg, the first accommodating groove).

[0091] In some embodiments, the driving platform 102 further includes a second lead screw 1022 , which is disposed on the driving platform body 1021 , and the second lead screw 1022 is transmission-connected to the common bed board 300 .

[0092] Exemplarily, the second lead screw 1022 may also be a ball screw. When the second lead screw 1022 is a ball screw, the transmission structure between the second lead screw 1022 and the common bed board 300 is consistent with the transmission structure between the first lead screw 103 and the drive platform 102. This application will not repeat this. Another exemplary embodiment, the second lead screw 1022 may be a trapezoidal lead screw, which is not limited in this application.

[0093] In some embodiments, the driving platform 102 also includes a second driving component 1023, which is disposed on the driving platform body 1021. The second driving component 1023 is transmission-connected to the second lead screw 1022. The second driving component 1023 is used to drive the second lead screw 1022 to rotate so that the common bed bed board 300 moves along the first coordinate axis relative to the driving platform body 1021, that is, so that the common bed bed board 300 moves along the positive direction or negative direction of the Y-axis relative to the driving platform body 1021.

[0094] Among them, the specific transmission relationship between the second driving component 1023, the second screw 1022 and the common bed board 300 can refer to the transmission relationship between the first driving component 104, the first screw 103 and the driving platform 102, and this application will not elaborate on this.

[0095] See also Figure 3 Combined with Figure 4 The following is an exemplary description using the example in which the second driving component 1023 drives the second lead screw 1022 to rotate clockwise and the shared bed board 300 moves relative to the driving platform body 1021 along the positive direction of the Y-axis.

[0096] When the patient completes the corresponding diagnosis and treatment task at the first target position, the second drive component 1023 is started, and the second drive component 1023 drives the second screw 1022 to rotate clockwise. The shared bed board 300 moves relative to the drive platform 102 along the positive direction of the Y-axis. At this time, the shared bed board 300 moves along the positive direction of the Y-axis. The specific position of the shared bed board 300 can be controlled by controlling the number of rotations of the second screw 1022. As the second screw 1022 continues to rotate, the shared bed board 300 detaches from the second screw 1022 and the drive platform 102. At this time, the receiving platform 202 receives the shared bed board 300 and continues to move. On this basis, the shared bed board 300 completes the work of moving from the first support device 100 to the second support device 200.

[0097] In some embodiments, the shared bed board 300 is provided with a nut seat, which is fixedly connected to the shared bed board 300. The shared bed board 300 is threadedly connected to the second screw 1022 through the nut seat. When the second screw 1022 rotates clockwise, the nut seat moves along the positive direction of the Y-axis to drive the shared bed board 300 to move along the positive direction of the Y-axis; when the second screw 1022 rotates counterclockwise, the nut seat moves along the negative direction of the Y-axis to drive the shared bed board 300 to move along the negative direction of the Y-axis.

[0098] In other embodiments, along the positive direction of the Y-axis, the nut seat is arranged at the front end of the shared bed board 300, so that when the nut seat is disengaged from the second screw 1022, at least most of the shared bed board 300 can be transferred to the second supporting device 200, and at the moment when the nut seat is disengaged from the second screw 1022, the shared bed board 300 and the second supporting device 200 are in a stable state.

[0099] In some embodiments, see Figure 1 The driving platform 102 also includes a push block 1024, which is transmission-connected to the second lead screw 1022. When the second lead screw 1022 rotates to drive the common bed board 300 to move along the first coordinate axis relative to the driving platform body 1021, it also drives the push block 1024 to move along the first coordinate axis.

[0100] In other words, along the positive direction of the Y-axis, the push block 1024 is located at the front end of the common bed board 300 .

[0101] Furthermore, the push block 1024 is located at the front end of the nut seat.

[0102] Among them, see Figure 3 The specific transmission relationship between the push block 1024 and the second lead screw 1022 can refer to the transmission relationship between the nut seat and the first lead screw 103 and the driving platform 102, and this application will not go into details.

[0103] The following is an exemplary description using an example in which the second driving assembly 1023 drives the second lead screw 1022 to rotate clockwise and the push block 1024 moves relative to the driving platform body 1021 along the positive direction of the Y axis.

[0104] On this basis, after the shared bed board 300 is disengaged from the driving platform 102, the second lead screw 1022 continues to rotate clockwise and drives the push block 1024 to continue to move along the first coordinate axis (i.e., the positive direction of the Y axis) to push the shared bed board 300 to move to the target position along the receiving platform 202. For ease of distinction, in this application, the target position where the receiving platform 202 drives the shared bed board 300 to move is the second target position.

[0105] In this way, due to the cooperation of the second lead screw 1022 and the push block 1024, the position of the shared bed board 300 on the second supporting device 200 can be further calibrated and fine-tuned to ensure that the shared bed board 300 moves to the second target position.

[0106] It can be understood that the second target position is the position where the receiving platform 202 receives the shared bed board 300. For details, please refer to the explanation of the receiving platform 202 below in this application.

[0107] Of course, when the second screw 1022 rotates counterclockwise, the second screw 1022 can also drive the push block 1024 to move along the negative direction of the Y-axis to avoid the push block 1024 being located at the end of the second screw 1022 affecting the connection between the second screw 1022 and the common bed board 300.

[0108] In some embodiments, see Figure 4 The driving platform body 1021 is provided with a second slide rail 1025, and the push block 1024 is slidably connected to the second slide rail 1025. Therefore, when the push block 1024 moves along the positive direction and the negative direction of the Y-axis, it can slide along the second slide rail 1025. Under the guiding action of the second slide rail 1025, the position deviation of the push block 1024 can be avoided, thereby affecting the common bed board 300 pushed by it.

[0109] In the above process, the second lead screw 1022 plays a role in floating positioning for the push block 1024, the nut seat and the common bed board 300. The floating positioning of the second lead screw 1022 means that the second lead screw 1022 has a certain adaptive adjustment ability and can flexibly change its own position or state within a certain range to achieve accurate positioning and stable support for the push block 1024, the nut seat and the common bed board 300. In other words, the second lead screw 1022 allows it to be adaptively adjusted within a certain degree of freedom, and these errors are compensated by the second lead screw 1022's own slight displacement or angle change, so that the push block 1024, the nut seat and the common bed board 300 can still maintain an accurate position relationship.

[0110] In some embodiments, the second drive assembly 1023 includes a drive motor 1023 a that provides power for the movement of the second lead screw 1022 .

[0111] The second driving assembly 1023 includes a driving pulley 1023b, a synchronous belt 1023c and a passive pulley 1023d, wherein the driving pulley 1023b is connected to the output end of the driving motor 1023a, and the driving motor 1023a is used to drive the driving pulley 1023b to rotate. The synchronous belt 1023c is partially wound around the driving pulley 1023b, and the synchronous belt 1023c is partially wound around the passive pulley 1023d, and the output end of the passive pulley 1023d is connected to the second lead screw 1022, and the driving pulley 1023b drives the passive pulley 1023d to rotate through the synchronous belt 1023c, so as to drive the second lead screw 1022 to rotate.

[0112] Under the action of the driving motor 1023a, when the driving motor 1023a starts to rotate, its output shaft will drive the driving pulley 1023b to rotate synchronously. The driving pulley 1023b is like the starting "driving wheel" of the transmission system, which transmits the power generated by the driving motor 1023a. The driving pulley 1023b relies on the meshing with the synchronous belt 1023c and the transmission characteristics of the synchronous belt 1023c itself to transmit the power to the passive pulley 1023d, and the passive pulley 1023d receives the power transmitted from the synchronous belt 1023c, thereby driving the lead screw to rotate.

[0113] The driving motor 1023a has high-precision position and speed control capabilities, and can accurately drive the active pulley 1023b to rotate, and transmit it to the passive pulley 1023d through the synchronous belt 1023c, and finally accurately control the rotation of the lead screw, thereby achieving precise positioning and smooth speed change of the shared bed board 300 on the preset path, and the synchronous belt 1023c has smooth transmission, which can effectively reduce the vibration and noise generated by the shared bed board 300 during movement, creating a comfortable environment for patients and ensuring stable operation of the equipment.

[0114] In some embodiments, the driving components in the present application (such as the first driving component 104, the second driving component 1023 and the third driving component 204) are provided with a shielding layer.

[0115] For example, the housings of the driving motor 1023a and the driving pulley 1023b are made of materials with good electromagnetic shielding performance. On the control circuit board of the driving motor 1023a, metal shielding covers are used to isolate sensitive electronic components and circuit parts.

[0116] In another exemplary embodiment, all the wires of the driving assembly can be double-layer electromagnetic shielding wires. Double-layer shielding wires are composed of two shielding layers and an insulating layer in the middle. The outer shielding layer is usually made of metal braided mesh or metal foil, which has high mechanical strength and good electromagnetic shielding performance; the inner shielding layer is generally made of tinned copper wire braided mesh or aluminum foil, which has better high-frequency shielding effect.

[0117] Electromagnetic shielding can effectively prevent the propagation of electromagnetic interference of drive components, ensure the normal operation and coordinated work of the diagnosis and treatment system, and improve the safety and reliability of the diagnosis and treatment process.

[0118] In other embodiments, the transmission relationship between the first drive component 104 and the first screw 103, the third drive component 204 and the third screw 203, and the transmission structure between the second drive component 1023 and the third screw 203 may be consistent or inconsistent, and this application does not make any limitation on this.

[0119] In some embodiments, under the action of the second driving assembly 1023, as the second screw 1022 continues to rotate clockwise, the shared bed board 300 detaches from the second screw 1022, and the shared bed board 300 after detachment is received by the receiving platform 202, which drives the shared bed board 300 to continue to move on the second support base 201.

[0120] In some embodiments, see Figure 3 The second supporting device 200 also includes a matching piece and a locking piece 2021. The matching piece is arranged on the common bed board 300, and the locking piece 2021 is arranged on the receiving platform 202. When the common bed board 300 moves to the target position (i.e., the second target position) of the receiving platform 202, the locking piece 2021 locks the matching piece to fix the common bed board 300 at the second target position.

[0121] When the shared bed board 300 moves to the second target position of the receiving platform 202, the locking piece 2021 locks the matching piece. In this way, when the receiving platform 202 drives the shared bed board 300 to move, the shared bed board 300 can be fixed on the receiving platform 202 without shaking. The receiving platform 202 can accurately move the shared bed board 300 to the next target position, that is, the receiving platform 202 can accurately move the shared bed board 300 to the third target position.

[0122] The third target position may be the second working position corresponding to the patient during the diagnosis and treatment process. Exemplarily, the third target position may be the treatment position corresponding to the patient during the diagnosis and treatment process.

[0123] In some embodiments, the locking member 2021 may be an electromagnetic locking device, and the locking member 2021 and the matching member are connected by electromagnetic force, and the locking member 2021 can tightly adsorb the matching member by magnetic force to achieve the locking function, thereby firmly fixing the shared bed board 300 on the receiving platform 202. The electromagnetic locking device can achieve fast locking and unlocking operations.

[0124] In a medical environment, the diagnosis and treatment process is often relatively compact. For example, when the shared bed board 300 completes a link and moves to the second target position and needs to be fixed, and then quickly moves to the next treatment position (third target position), the electromagnetic locking device can respond to the control system's instructions in a very short time and complete the corresponding action, effectively improving the overall operating efficiency of the equipment, reducing waiting time, and ensuring the continuity of the diagnosis and treatment process.

[0125] In another exemplary embodiment, the locking member 2021 may be a mechanical clamping device, and the locking member 2021 is clamped with the matching member to achieve the purpose of fixing and positioning. The mechanical clamping device can provide stable positioning support and is not prone to loosening or displacement.

[0126] In some embodiments, the second supporting device 200 also includes an elastic pushing member 2022, which is disposed on the receiving platform 202. After the common bed board 300 is separated from the driving platform 102 and before it moves to the target position, the elastic pushing member 2022 is used to apply a first elastic force directed to the push block 1024 to the common bed board 300, so that the common bed board 300 abuts against the push block 1024, thereby ensuring that the push block 1024 can further calibrate the moving position of the common bed board 300 after the common bed board 300 is separated from the second screw 1022.

[0127] In other embodiments, after the locking member 2021 is unlocked, the elastic pushing member 2022 is also used to apply a second elastic force directed to the second screw 1022 to the common bed board 300 to drive the common bed board 300 to move along the first coordinate axis toward the driving platform 102 and make the common bed board 300 engage with the second screw 1022.

[0128] It can be understood that when the shared bed board 300 moves to the receiving platform 202, the elastic pusher 2022 can apply an elastic force to the shared bed board 300 along the negative direction of the Y-axis. As the moving target position of the shared bed board 300 is different, the role of the elastic force is also different. Therefore, in order to facilitate distinction, in this application, when the shared bed board 300 still needs to move to the third target position, the force applied by the elastic pusher 2022 is the first elastic force; and when the shared bed board 300 needs to be docked with the second screw, the force applied by the elastic pusher 2022 is the second elastic force.

[0129] When the shared bed board 300 still needs to be moved to the third target position, the second lead screw 1022 rotates clockwise, and under the action of the first elastic force, the nut seat of the shared bed board 300 contacts the push block 1024, and the push block 1024 can continue to push the nut seat to calibrate the position of the shared bed board so that it can be accurately moved to the second target position on the receiving platform 202. In the present application, the second target position is the position where the locking piece 2021 is locked with the mating piece.

[0130] Before the shared bed board 300 needs to be docked with the second lead screw 1022, the second lead screw 1022 rotates counterclockwise, and the push block 1024 first moves a distance along the negative direction of the Y-axis. When the shared bed board 300 needs to be docked with the second lead screw 1022, the locking piece 2021 unlocks the mating piece, and under the action of the second elastic force, the nut seat of the shared bed board 300 is re-screwed into the peripheral side of the second lead screw 1022 and is re-threadedly connected to the second lead screw 1022. As a result, the second lead screw 1022 can drive the shared bed board 300 back to the driving platform body 1021.

[0131] In some embodiments, see Figure 5 The second supporting device 200 also includes a third screw 203 , which is disposed on the second supporting base 201 and is transmission-connected to the receiving platform 202 .

[0132] Among them, the connection relationship between the third screw 203 and the receiving platform 202 can refer to the connection relationship between the first screw 103 and the driving platform 102, and can also refer to the connection relationship between the second screw 1022 and the common bed board 300. This application will not go into details.

[0133] In some embodiments, the second support device 200 also includes a third drive component 204, which is disposed on the second support base 201 and is transmission-connected to the third screw 203. The third drive component 204 is used to drive the third screw 203 to rotate to drive the support platform to move along the first coordinate axis.

[0134] Among them, the specific transmission relationship between the third driving component 204, the third screw 203 and the receiving platform 202 can refer to the transmission relationship between the nut seat and the first screw 103 and the driving platform 102, and this application will not elaborate on this.

[0135] The rear end of the shared bed board 300 is connected to the receiving platform 202 along the positive direction of the Y-axis, and the third driving component 204 drives the third screw 203 to rotate clockwise, and the receiving platform 202 drives the shared bed board 300 to move to the third target position along the positive direction of the Y-axis. When the patient completes treatment at the third target position, the third driving component 204 drives the third screw 203 to rotate counterclockwise, so that the receiving platform 202 drives the shared bed board 300 to move to the second target position. At this time, the shared bed board 300 can dock with the second screw 1022 to return to the driving platform 102 body.

[0136] In some embodiments, see Figure 1The first supporting device 100 further includes a third supporting base 106, which is located between the first supporting base 101 and the second supporting base 201. When the driving platform 102 moves along the positive direction of the Y axis under the driving action of the first driving assembly 104 and the first lead screw 103, the rear end of the driving platform 102 along the positive direction of the Y axis can overlap on the third supporting base 106, so that when the shared bed board 300 is diagnosed at the first target position, the third supporting base 106 can provide stable support force for the driving platform 102 and the shared bed board 300.

[0137] Exemplarily, the third supporting base 106 includes a first supporting rear body 1061 , and the first supporting rear body 1061 is used to support the rear end of the driving platform 102 along the positive direction of the Y-axis.

[0138] In other embodiments, the first support device 100 further includes a first support bridge 105, the first support bridge 105 is connected between the first support base 101 and the third support base 106, the first support bridge 105 is used to support the driving platform 102, and the first support bridge 105 is provided with a guide rail capable of sliding the driving platform 102. When the first lead screw 103 rotates, the first lead screw 103 can drive the driving platform 102 to move along the first coordinate axis, and the driving platform 102 is partially separated from the first lead screw 103, and the portion of the driving platform 102 separated from the first lead screw 103 can be carried on the first support bridge 105, and when the driving platform 102 is driven to the end of the first lead screw 103, the driving platform 102 is carried on the first support bridge 105.

[0139] Specifically, the first supporting bridge 105 is connected between the first front supporting body 1011 of the first supporting base 101 and the first rear supporting body 1061 of the third supporting base 106 .

[0140] Correspondingly, the guide rail on the first support bridge 105 is connected to the first support front body 1011 along the negative direction of the Y-axis toward one end of the first support front body 1011, and can receive the part of the driving platform 102 that is detached from the first support front body 1011, so that the driving platform 102 can move smoothly on the first support front body 1011, the first support bridge 105 and the first support back body 1061.

[0141] It should be noted that the docking here means that the first support bridge 105 can timely receive the part of the driving platform 102 that is separated from the front body 1011 of the first support at least along the X-axis direction, Y-axis direction and Z-axis direction shown in the figure.

[0142] In other embodiments, in order to ensure a stable connection between the driving platform 102 and the first supporting rear body 1061 when the driving platform 102 moves to the first target position, a second accommodating groove is provided on the first supporting rear body 1061, and the specific structure of the second accommodating groove is consistent with the structure of the first accommodating groove, thereby preventing the first supporting rear body 1061 from obstructing the subsequent movement of the shared bed board 300.

[0143] It should be noted that the "front" and "rear" in the first support front body 1011 and the first support rear body 1061 are only descriptions of the front and rear in the Y-axis direction, and do not constitute a limitation on the order in this application. The moving direction of the shared bed board 300 and the driving platform 102 can be from the first support front body 1011 to the first support rear body 1061, or from the first support rear body 1061 to the first support front body 1011, and this application does not limit this.

[0144] In some embodiments, see Figure 1 The first support device 100 in the present application further includes a second support bridge 107, and the second support bridge 107 is connected between the first support base 101 and the third support base 106. Like the first support bridge 105, the second support bridge 107 is connected between the first support front body 1011 of the first support base 101 and the first support rear body 1061 of the third support base 106. The shared bed board 300 can move along the first platform composed of the first support base 101, the second support bridge 107 and the third support base 106.

[0145] When the driving platform 102 moves to the first support bridge 105, the driving platform 102 can continue to drive the common bed board 300 to move along the positive direction of the Y-axis to the second support bridge 107, and the shared bed board 300 can move along the second support bridge 107, wherein the second support bridge 107 provides a special motion support structure for the shared bed board 300, that is, the second support bridge 107 is provided with a guide rail for the shared bed board 300 to move.

[0146] In this way, the driving platform 102 and the common bed board 300 can move stably when the first supporting device 100 moves, thereby ensuring the comfort of the patient and the reliability of the overall equipment.

[0147] In some embodiments, see Figure 3 The second supporting device 200 further includes a fourth supporting base 205 , and the fourth supporting base 205 is disposed on a side of the second supporting base 201 away from the first supporting base 101 .

[0148] Similar to the matching relationship between the first support base 101 and the third support base 106, the second support base 201 is used to support the front end of the shared bed board 300 along the Y-axis direction, and the fourth support base 205 is used to support the rear end of the shared bed board 300 along the Y-axis direction, so that the patient can smoothly undergo treatment at the third target position and ensure the stability of the shared bed board 300.

[0149] Correspondingly, the second support base 201 includes a second support front body 2011, and the fourth support base 205 includes a second support rear body 2051. The matching relationship between the second support front body 2011 and the second support rear body 2051 can refer to the first support front body 1011 and the first support rear body 1061, and this application will not go into details.

[0150] In some embodiments, the second support device 200 further includes a third support bridge 206, and the third support bridge 206 is connected between the second support base 201 and the fourth support base 205, that is, the third support bridge 206 is connected between the second support front body 2011 and the second support rear body 2051. The shared bed board 300 can move along the second platform composed of the second support base 201, the third support bridge and the fourth support base 205.

[0151] See also Figure 2 The shared bed board 300 can move along the supporting device composed of the second supporting base 201, the fourth supporting base 205 and the third supporting bridge 206. In other words, in the process of the shared bed board 300 driven by the supporting platform 202 to move, the second supporting base 201, the fourth supporting base 205 and the third supporting bridge 206 provide favorable support for the shared bed board 300 to ensure the stability of the shared bed board 300 during the movement.

[0152] In some embodiments, the first supporting bridge 105 , the second supporting bridge 107 , and the third supporting bridge 206 can all be carbon fiber square columns.

[0153] The carbon fiber material itself has extremely high strength. The carbon fiber material bears the weight of the shared bed board 300 and the patient, as well as various loads such as the pressure exerted during the movement. The carbon fiber square column structure can also maintain good structural integrity and is not prone to bending and deformation. It effectively guarantees the support stability during movement and ensures that the shared bed board 300 can slide smoothly.

[0154] In some embodiments, the fourth support base 205 and the second support base 201 in the present application may also be provided with corresponding accommodating grooves, and the shape of the accommodating grooves is matched with the shape of the shared bed board 300, so that the moving path formed by the shared bed moving device in the present application is always guaranteed to be on a straight line along the Y-axis direction, and can also realize multi-directional adjustment requirements, providing a stable support platform for the shared bed board 300, reducing the patient's discomfort and potential risk of body position changes during treatment.

[0155] In some embodiments, see Figure 3 The first support base 101 is further provided with a first guide rail 1013. For example, the first guide rail 1013 is provided on the first support front body 1011 and is extended to the second support bridge 107 and the third support base 106; the shared bed board 300 is slidably connected to the first guide rail 1013. In this way, the first guide rail 1013 can support the shared bed board 300, so as to prevent the shared bed board 300 and the patient from exerting a large pressure on the driving platform 102 and damaging it.

[0156] In some embodiments, the extension direction of the first guide rail 1013 is set along the Y-axis. In this way, the first guide rail 1013 can also guide the common bed board 300 to avoid deviation in the position of the common bed board 300 when the driving platform 102 drives the common bed board 300 to move.

[0157] In some embodiments, the first guide rail 1013 is disposed in the first accommodating groove to reduce the gap between the common bed board 300 and the first support front body 1011 along the Z-axis direction, thereby improving the integration of the first support device 100.

[0158] In other embodiments, in order to further improve the supporting effect of the first guide rail 1013 on the shared bed board 300, the setting method of the first guide rail 1013 is consistent with the setting method of the above-mentioned first slide rail 1012, and this application will not go into details.

[0159] In some embodiments, see Figure 6 The second support device also includes a second guide rail 207. Exemplarily, the second guide rail 207 is arranged on the front body 2011 of the second support and is extended on the third support bridge 206 and the third support bridge 206, so that the shared bed board 300 can move smoothly along the positive direction or negative direction of the Y-axis on the front body 2011 of the second support.

[0160] In some embodiments, see Figure 3A third slide rail 208 is disposed on the front body 2011 of the second support, and the receiving platform 202 can slide along the third slide rail 208 . The third slide rail 208 provides a clear and precise linear moving path for the receiving platform 202 .

[0161] In some embodiments, see Figure 1 The shared bed board 300 is provided with at least one rolling member 301. With the help of the at least one rolling member 301, the shared bed board 300 can roll on the first platform composed of the first support base 101, the second support bridge 107 and the third support base 106, specifically, can roll on the first guide rail 1013, and / or can roll on the second platform composed of the second support base 201, the third support bridge and the fourth support base 205, specifically, can roll on the second guide rail 207. The use of the rolling member 301 changes the friction mode between the shared bed board 300 and the first platform and / or the second platform from sliding friction to rolling friction, so as to improve the reliability and speed of the shared bed board 300 during movement.

[0162] In some embodiments, the rolling element 301 may be a raceway bearing disposed on the common bed board 300 .

[0163] In other embodiments, the rolling member 301 may be a roller disposed on the bed board 300 of the shared bed.

[0164] In some embodiments, see Figure 1 The first support base 101 and the third support base 106 can move synchronously along the second coordinate axis and / or the third coordinate axis. And / or, the second support base 201 and the fourth support base 205 can move synchronously along the second coordinate axis and / or the third coordinate axis.

[0165] Exemplarily, the first coordinate axis is the Y axis, the second coordinate axis is the X axis, and the third coordinate axis is the Z axis.

[0166] When the first supporting device is a CT bed, the first supporting base 101 can drive the common bed board 300 to move along the Z axis in addition to the Y axis. Correspondingly, the second supporting base 201 can move along the Z axis synchronously.

[0167] When the second supporting device is a radiotherapy three-dimensional bed, the second supporting base 201 can drive the common bed board 300 to move along the X axis and the Z axis in addition to the Y axis. Correspondingly, the fourth supporting base 205 can move along the X axis and the Z axis synchronously.

[0168] On this basis, when the shared bed board 300 moves on the side of the first supporting device 100, the first supporting base 101 and the third supporting base 106 can move synchronously and correspondingly, which can ensure that the shared bed board 300 can move smoothly on the one hand; on the other hand, it can prevent the two ends of the components (such as the first supporting bridge 105) from being misaligned and damaged. Similarly, when the shared bed board 300 moves on the side of the second supporting device 200, the above effects can also be achieved, which will not be elaborated in this application.

[0169] At the same time, the first support base 101, the second support base 201 and the fourth support base 205 can also meet the requirements of synchronous position movement on the Y-axis, X-axis and Z-axis, so that the shared bed board 300 can move smoothly between the first support base 101, the second support base 201 and the fourth support base 205, further meeting the requirements of the shared bed board 300 moving between the first support device 100 and the second support device.

[0170] In some embodiments, see Figure 2 The second support base 201 also includes a lifting front column 2012 and a front body driving assembly 2013. Driven by the front body driving assembly 2013, the lifting front column 2012 can be lifted and lowered along the positive direction or negative direction of the Z axis, thereby driving the second support front body 2011 to lift and lower.

[0171] In some embodiments, the second support base 201 further includes an X-axis drive platform 2014 and an X-axis drive assembly, wherein the X-axis drive platform 2014 is disposed under the second support front body 2011, and the X-axis drive platform 2014 is transmission-connected with the second support front body 2011. Under the drive of the X-axis drive assembly, the X-axis drive platform 2014 drives the second support front body 2011 to move along the positive direction or negative direction of the X-axis. On this basis, the lifting front column 2012 is disposed under the X-axis drive platform 2014, so that the second support device can move in the X-axis, Y-axis and Z-axis.

[0172] In some embodiments, the X-axis driving platform 2014 and the second support front body 2011 may be connected via an X-axis guide rail and an X-axis slider.

[0173] In some embodiments, see Figure 1 The fourth support base 205 further includes a lifting rear column 2052, which can be lifted and lowered along the positive direction or negative direction of the Z axis, thereby driving the second support rear body 2051 to be lifted and lowered. The lifting rear column 2052 can be synchronously driven by the front body driving component 2013, or driven by an independent rear body driving component.

[0174] In some embodiments, the present application also provides a diagnosis and treatment system, see Figure 1 Combined with Figure 2 as well as Figure 3 The diagnosis and treatment system includes a radiotherapy device 500 and an imaging device 400 . The radiotherapy device 500 has a radiotherapy position 501 , and the imaging device 400 has an imaging position 401 .

[0175] The diagnosis and treatment system also includes the above-mentioned shared bed moving device, and the first supporting device 100 and the second supporting device 200 of the shared bed moving device can drive the shared bed board 300 to move between the radiotherapy position 501 and the imaging position 401.

[0176] For example, see Figure 1 Combined with Figure 2 as well as Figure 3 The first support base 101 and the third support base 106 are located on both sides of the imaging position 401 along the horizontal direction of the Y axis, and the second support base 201 and the fourth support base 205 are located on both sides of the radiotherapy position 501 along the horizontal direction of the Y axis.

[0177] Based on the above-mentioned technical means, on the one hand, the diagnosis and treatment involved in this application does not require system integration of the imaging device 400 and the radiotherapy device 500, thus avoiding huge costs. Instead, the shared bed moving device is controlled to transfer the shared bed board 300 between the imaging device 400 and the radiotherapy device 500 to smoothly, accurately and quickly transfer the patient, thereby ensuring that the patient's position on the imaging device 400 and the radiotherapy device 500 is completely consistent, thereby improving the accuracy of radiotherapy and enabling the radiation to more accurately irradiate the tumor target area.

[0178] On the other hand, the system in the present application not only improves the adaptive radiotherapy function based on the imaging device 400, such as a CT device, but also optimizes the diagnosis and treatment process to make it smoother and more efficient. For example, after the patient is imaged and waiting for radiotherapy (i.e., the time for adaptively adjusting the treatment plan based on the image acquired by the imaging device 400), the shared bed is automatically transferred from the imaging position 401 to the radiotherapy position 501 at a low speed and stability, so that the patient can receive radiotherapy when he arrives at the radiotherapy position 501, which greatly shortens the patient's waiting time for radiotherapy, improves the efficiency of diagnosis and treatment, makes the entire adaptive process more compact, reduces the patient's stay time in the treatment room, and improves the turnover rate of the treatment room.

[0179] In some embodiments, the imaging device 400 in the present application includes at least one of a nuclear magnetic resonance device, a CT device, and a PET device, which is not limited in the present application. The present application uses the imaging device 400 as a CT device for exemplary description.

[0180] It can be understood that, according to different arrangements of the diagnosis and treatment system, the shared bed moving device in the present application can also realize the conversion between multiple imaging devices 400 and multiple radiotherapy devices 500.

[0181] It should be noted that the application scenario mentioned in this application is only one scenario in the actual application of the shared bed moving device. It can also be applied in other required scenarios, and this application does not limit this.

[0182] In some embodiments, the materials used in the diagnosis and treatment system of the present application are radiation-resistant, non-magnetic, and non-conductive, and can meet the requirements of ultraviolet and chemical disinfection treatment.

[0183] In some embodiments, the first lead screw 103, the second lead screw 1022 and the third lead screw 203 in the present application can all be non-metallic lead screws.

[0184] On the one hand, different imaging devices 400 have different sensitivities and compatibilities to metals. Using a non-metallic lead screw can improve the compatibility of the device with various imaging technologies, making it better suited to a variety of imaging needs.

[0185] On the other hand, during radiotherapy, metal wires will absorb and scatter radiotherapy rays, affecting the dose distribution and treatment effect. Non-metal wires have minimal absorption and scattering effects on radiotherapy rays, ensuring that radiotherapy rays are accurately irradiated to the tumor site according to the predetermined plan, improving the accuracy and efficacy of radiotherapy.

[0186] The following will be based on Figure 3 The diagnosis and treatment system shown introduces the entire diagnosis and treatment process.

[0187] (1) Scanning imaging preparation.

[0188] Before the entire diagnosis and treatment work begins, the first support base 101 and the third support base 106 descend along the Z-axis direction, thereby driving the drive platform 102 and the shared bed board 300 to descend, so that the shared bed board 300 can smoothly carry the patient. After the patient lies on the shared bed board 300 and is ready, the first support base 101 drives the drive platform 102 and the shared bed board 300 to rise along the Z-axis direction to the imaging height, and the manually operated imaging device 400 positions the positioning laser line roughly at the center of the tumor to position the patient.

[0189] It should be noted that, in order to avoid the second supporting device 200 from interfering with the common bed board 300 when imaging at the imaging position 401, the height of the second supporting device 200 is lower than the height of the imaging position 401. Furthermore, the second supporting base 201 and the fourth supporting base 205 are lowered to their lowest positions on the Y-axis.

[0190] (2) Scanning imaging process.

[0191] After the patient is positioned, the diagnostic scanning imaging work is started, the first drive component 104 is controlled to start, the first screw 103 is rotated, and the drive platform 102 and the shared bed board 300 are transported along the positive direction of the Y-axis into the imaging position 401. The imaging position 401 is the first target position in this application. The drive platform 102 moves to the first support bridge 105, and the shared bed board 300 moves to the second support bridge 107. The imaging device 400 images the patient on the shared bed board 300.

[0192] Exemplarily, the imaging device 400 may perform imaging on the patient according to the determined scanning range and sequence.

[0193] (3) The shared bed board 300 is in the transfer preparation state.

[0194] When the diagnostic scan is completed, the shared bed board 300 located at the imaging position 401 is driven by the driving platform 102, and the end of the shared bed board 300 moves along the Y-axis direction to a position flush with the rear end of the third support base 106, and then (or simultaneously) the second support base 201 and the fourth support base 205 rise along the Z-axis direction, and the second support base 201 and the fourth support base 205 are flush with the third support base 106 along the Z-axis, so that the receiving platform 202 can be smoothly received by the shared bed board 300.

[0195] The specific docking process can be referred to the previous description, and this application will not go into details.

[0196] (4) The common bed board 300 is transferred to a locked state.

[0197] Under the driving action of the driving platform 102, the shared bed board 300 moves to the receiving platform 202 along the positive direction of the Y-axis, and the locking piece 2021 on the receiving platform 202 locks the matching piece on the shared bed board 300, so that the shared bed board 300 can be fixed on the receiving platform 202. At this time, the position of the shared bed board 300 is the second target position in this application.

[0198] At this time, the elastic pusher 2022 on the receiving platform 202 can cooperate with the push block 1024 of the first supporting device 100 to further ensure that the shared bed board 300 can be moved to the second target position. Please refer to the above for specific instructions, and this application will not go into details.

[0199] (5) The shared bed board 300 is transferred to the treatment state.

[0200] When the shared bed board 300 is in a locked state on the receiving platform 202, the third driving assembly 204 is controlled to transport the shared bed board 300 along the positive direction of the Y-axis into the radiotherapy position 501, the shared bed board 300 moves to the third supporting bridge 206, and the radiotherapy equipment 500 performs radiotherapy on the patient on the shared bed board 300.

[0201] Exemplarily, the radiotherapy device 500 uses high-energy rays to irradiate diseased tissues such as tumors to achieve the purpose of treating tumors.

[0202] (6) The shared bed board 300 moves from the radiotherapy position 501 back to the upper and lower bed positions of the imaging device 400.

[0203] After the radiotherapy is completed, the receiving platform 202 drives the shared bed board 300 to move out of the radiotherapy position 501, and the third screw 203 rotates counterclockwise to make the shared bed board dock with the second screw 1022. The second screw 1022 rotates counterclockwise, and the shared bed board 300 can return to the driving platform 102. Further, the first screw 103 rotates counterclockwise, and the driving platform 102 can drive the shared bed board 300 back to the position where the patient originally got on and off the bed.

[0204] Finally, this application takes the imaging device 400 as a CT device as an example to introduce the adaptive radiotherapy workflow based on the diagnosis and treatment system, which includes:

[0205] 1) After the patient completes the planned positioning scan, an accurate treatment plan is designed based on the acquired imaging data. Subsequently, the treatment plan successfully passed the rigorous review process and was finally officially approved and is about to enter the implementation stage.

[0206] 2) The treatment is officially started, and the patient is smoothly sent to the CT adaptive radiotherapy room and pre-positioned on the scanning bed of the system-integrated CT equipment, that is, the patient lies on the common bed board 300 located on the first supporting device 100.

[0207] 3) The medical staff exits the treatment room, operates the CT equipment (or central control console), performs positioning and scanning imaging, and obtains image data that meets the doctor's needs; these image data are then quickly and stably transmitted to the patient's TPS database; at the same time, the second drive component 1023 is started to start the transfer procedure of the shared bed board 300.

[0208] It should be noted that the movement speed of the shared bed board 300 needs to be controlled to effectively prevent the patient from being displaced due to improper speed, thereby fully ensuring the patient's safety and the accuracy of treatment.

[0209] 4) After TPS receives the image sequence obtained by the MRI scan, professionals quickly and accurately outline the target area and critical organs. Then, based on the target area, the target area, target point and dose field data in the original plan are cleverly translated and integrated into the three-dimensional reconstruction space of the MRI image, and the MRI image coordinates are selected as position parameters to construct a new treatment plan model. Next, a comprehensive evaluation of this re-planned plan is carried out, and the plan parameters are adjusted slightly and carefully based on the various indicators presented during the evaluation process. This operation is repeated until satisfactory evaluation results in all aspects are obtained.

[0210] 5) The radiotherapy device 500 runs the data, and the patient receives treatment in the radiotherapy position 501.

[0211] 6) After the radiotherapy equipment 500 is finished running, the position of the shared bed board 300 is further moved according to specific needs.

[0212] Exemplarily, after radiotherapy is completed, driven by the receiving platform 202, the shared bed board 300 first returns to the initial position of the driving platform 102, and then follows the driving platform 102 to return to the patient's original getting on and off the bed.

[0213] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
