Description

Technical Field

[0001] This application belongs to the field of medical device technology, and in particular relates to a diagnostic and treatment device. Background Technology

[0002] With the development and innovation of high-end medical equipment, integrated diagnostic and therapeutic devices, primarily guided by CT (Computed Tomography) imaging, are becoming increasingly sophisticated. These devices effectively improve diagnostic and treatment efficiency and reduce medical costs, gaining widespread acceptance from hospitals and patients. To meet diverse treatment needs, the treatment beds used in these devices feature multiple motion dimensions and high motion precision.

[0003] Currently, treatment beds are mostly complex in structure and bulky in general. They are often installed separately from the main body of the diagnostic and treatment equipment, and their integration with the main body of the diagnostic and treatment equipment needs to be improved. In addition, when a patient is placed on the treatment bed, it is often necessary to move it up, down, forward, backward, left and right to reach the treatment position of the main body of the diagnostic and treatment equipment. Therefore, the placement efficiency of the treatment bed needs to be improved. Summary of the Invention

[0004] The purpose of this application is to provide a diagnostic and treatment device to solve the technical problem of low integration between the treatment bed and the main body of the diagnostic and treatment device in the prior art.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] This application provides a diagnostic and treatment device, comprising:

[0007] The main body of the diagnostic and treatment equipment includes a rotor with a scanning hole formed in the middle;

[0008] The position adjustment mechanism is located on the main body of the diagnostic and treatment equipment;

[0009] The bed is connected to a position adjustment mechanism, which is used to change the position of the bed relative to the main body of the diagnostic and treatment equipment.

[0010] In some implementations, the position adjustment mechanism includes a rotation adjustment device, which includes an arc-shaped track structure and a drive structure. The arc-shaped track structure is set on the main body of the diagnostic and treatment equipment, and the drive structure is connected to the arc-shaped track structure and the bed. Driven by the drive structure, the bed can move along the arc-shaped track structure into or out of the scanning aperture.

[0011] In some implementations, the arc-shaped track structure includes a front adjustment seat, a middle beam, and a rear adjustment seat. The front and rear adjustment seats are respectively located on the front and rear sides of the main body of the diagnostic and treatment equipment along the axis of the scanning hole. The middle beam is mounted on the rotor. When the rotor drives the middle beam to rotate to a preset position, the two ends of the middle beam are aligned with the front and rear adjustment seats, so that the tops of the front adjustment seat, the middle beam, and the rear adjustment seat form an arc shape. The drive structure includes a front drive structure and a rear drive structure. When the bed is inserted into the scanning hole and is in a horizontal state, the front drive structure is connected to the front adjustment seat, and the rear drive structure is connected to the rear adjustment seat.

[0012] In some implementations, the arc length of the top surface of the front adjustment seat is greater than the arc length of the top surface of the rear adjustment seat.

[0013] In some implementations, the top surfaces of the front adjusting seat, the intermediate beam, and the rear adjusting seat are all provided with teeth; both the front drive structure and the rear drive structure include a drive motor and a gearbox directly or indirectly connected to the drive motor, with the gearbox meshing with the teeth; or,

[0014] Both the front drive structure and the rear drive structure are arc-shaped frameless motors, and the motor stator of the arc-shaped frameless motor is set along the length direction of the arc-shaped track structure.

[0015] In some implementations, the top surfaces of the front adjusting seat, the intermediate beam, and the rear adjusting seat are all provided with teeth, and both the front drive structure and the rear drive structure include gearboxes that mesh with the teeth; slide rails are provided on the front adjusting seat, the intermediate beam, and the rear adjusting seat, and both the front drive structure and the rear drive structure include sliders or slip rings that cooperate with the slide rails.

[0016] In some implementations, the position adjustment mechanism also includes a linkage structure, in which the front adjustment seat and the rear adjustment seat are connected to the bed body via the linkage structure, which is used to adjust the position of the bed body relative to the main body of the diagnostic and treatment equipment.

[0017] In some implementations, the linkage structure includes a linear drive device, one end of which is hinged to the bed and the other end of which is hinged to the front drive structure or the rear drive structure; two or more linear drive devices are connected to the front drive structure; two or more linear drive devices are connected to the rear drive structure.

[0018] In some implementations, an adjustable pedal is provided at one end of the bed near the front adjustment seat. The length of the adjustable pedal is along the width of the bed, and the position of the adjustable pedal on the bed along the length of the bed is adjustable.

[0019] In some implementations, the axis of rotation of the bed as it rotates along the arc-shaped track structure is perpendicular to the axis of the scanning aperture; when the bed rotates to a horizontal position, the center of the bed coincides with the center of the scanning surface and the center of the treatment surface of the main body of the diagnostic and treatment equipment.

[0020] The beneficial effects of this application are as follows: The diagnostic and treatment equipment provided in this embodiment integrates the bed body into the main body of the diagnostic and treatment equipment through a position adjustment mechanism, which not only simplifies the structure of existing diagnostic and treatment beds, but also reduces the indoor space occupied by existing diagnostic and treatment beds; In existing related technologies, when a patient is on the treatment bed, it is often necessary to move up and down, back and forth, left and right to reach the treatment position of the main body of the diagnostic and treatment equipment, while this embodiment integrates the bed body into the main body of the diagnostic and treatment equipment, which provides the possibility of improving the efficiency of bed positioning.

[0051] Please refer to the following: Figures 1-10 The diagnostic and treatment equipment provided in the embodiments of this application will now be described.

[0052] A diagnostic and treatment device includes a main body 1, a position adjustment mechanism, and a bed 2.

[0053] Please see Figure 1 and Figure 2The diagram illustrates the main body 1 of the diagnostic and treatment equipment and the bed 2. The main body 1 can be a computed tomography (CT) scanner, a magnetic resonance imaging (MRI) scanner, or a positron emission tomography (PET) scanner, etc. Under the action of the position adjustment mechanism, the patient lying on the bed 2 is inserted into the scanning port 11 of the main body 1, ensuring that the patient's examination area is correctly positioned on the scanning plane of the main body 1.

[0054] Regarding the main body of the diagnostic and treatment equipment (item 1), please refer to [link / reference]. Figure 2 Typically, the device includes a rotor 12, a frame slip ring 13, a frame and support base 14. The frame slip ring 13 is supported on the ground by the frame and support base 14. The rotor 12 is connected to the frame slip ring 13, and a scanning hole 11 is provided in the middle of the rotor 12. The rotor 12 can rotate relative to the frame slip ring 13. For the main body 1 of the diagnostic and treatment equipment supported on the ground, a foundation pit 51 is usually set on the ground (foundation 5). The size and depth of the foundation pit 51 are determined according to the diagnostic and treatment equipment. The bottom and sides of the foundation pit 51 are provided with shielding layers and decorative layers, etc.

[0055] The bed 2 provided in this embodiment is set on the main body 1 of the diagnostic and treatment equipment through a position adjustment mechanism, that is, the bed 2 is integrated on the main body 1 of the diagnostic and treatment equipment, which helps to simplify the structure of the treatment bed in the existing related technologies.

[0056] In this embodiment, the position adjustment mechanism can change the position of the bed 2 relative to the main body 1 of the diagnostic and treatment equipment. For example, when a patient needs to lie on the bed 2, the position adjustment mechanism can be used to adjust the bed 2 to a position where the patient can easily lie on it. Please refer to [link to relevant documentation]. Figure 5 , Figure 5 The diagram illustrates a positional state of the bed 2 relative to the main body of the diagnostic and treatment equipment 1. Figure 5 As shown, bed 2 is tilted, allowing the patient to easily lie down on it. Once the patient is lying on bed 2, its position can be adjusted using the position adjustment mechanism. Please refer to [link / reference needed]. Figures 1-4 This illustrates the state when the bed 2 is horizontal and positioned at the scanning port 11 of the main body 1 of the diagnostic and treatment equipment. At this time, the diagnostic and treatment examination can be performed on the patient lying on the bed 2 through the main body 1 of the diagnostic and treatment equipment. After the examination is completed, the position of the bed 2 can be changed via the position adjustment mechanism; for example, the bed 2 can be moved to a position such as... Figure 5 The indicated location is to facilitate the patient getting off the bed.

[0057] The diagnostic and treatment equipment provided in this embodiment integrates the bed body 2 into the main body 1 of the diagnostic and treatment equipment through a position adjustment mechanism. This not only simplifies the structure of existing diagnostic and treatment beds but also reduces the indoor space occupied by existing diagnostic and treatment beds. In existing related technologies, when a patient is on the treatment bed, it is often necessary to move it up, down, forward, backward, left, and right to reach the treatment position of the main body of the diagnostic and treatment equipment. However, this embodiment integrates the bed body 2 into the main body 1 of the diagnostic and treatment equipment, which makes it possible to improve the efficiency of bed positioning.

[0058] Regarding the position adjustment mechanism, in one embodiment, the position adjustment mechanism includes a rotation adjustment device 3, which is used to drive the bed 2 into or out of the scanning hole 11.

[0059] Please see Figure 2 The diagram illustrates the rotating adjustment device 3 located below the bed 2. When a patient needs to be placed on the bed 2, the position of the bed 2 can be adjusted by the rotating adjustment device 3 so that the bed 2 moves out of the scanning hole 11. When a patient lying on the bed 2 needs to be examined through the main body of the diagnostic and treatment equipment 1, the position of the bed 2 can be adjusted by the rotating adjustment device 3 so that the bed 2 moves into the scanning hole 11.

[0060] In this embodiment, based on the structural characteristics of the main body 1 of the diagnostic and treatment equipment, the movement trajectory of the bed 2 can be controlled to be arc-shaped via the rotation adjustment device 3. Please refer to [link / reference needed]. Figures 1-4 The bed 2 is positioned horizontally within the scanning aperture 11. When it needs to exit the scanning aperture 11, the bed 2 is rotated using the rotation adjustment device 3, causing it to be positioned with one end higher and the other lower, until the rotation adjustment device 3 rotates the bed 2 to the desired position. Figure 5 As shown in the diagram, since bed 2 is in a state where one end is low and the other end is high, it is very convenient to place the patient on bed 2.

[0061] As mentioned above, a foundation pit 51 is typically set up on the ground, and the main body 1 of the diagnostic and treatment equipment is supported within the foundation pit 51. In the example where the rotation adjustment device 3 controls the movement trajectory of the bed 2 to be in an arc shape, the dimensions of the foundation pit 51 on the ground must consider not only the main body of the diagnostic and treatment equipment 1 but also the bed 2. Please refer to... Figure 1 The diagram illustrates the bed-avoidance pit 511 and the main foundation pit 512. The bed-avoidance pit 511 is located on one side of the main foundation pit 512 and is connected to the main foundation pit 512. The main body 1 of the diagnostic and treatment equipment is supported within the main foundation pit 512. Please refer to... Figure 5When one end of the bed 2 is lowered to near the ground, the bed clearance pit 511 can accommodate a position adjustment mechanism (such as a rotation adjustment device 3), making it easier for patients to get on and off the bed when one end of the bed 2 is lowered to near the ground. Furthermore, the width b and length a of the bed clearance pit 511 should be appropriately set so that when the bed 2 is in such a position… Figure 5 When the bed body is tilted as shown, the gap between the two opposite side walls of the pit 511 and the bed body 2 along the direction parallel to the width of the bed body 2 is not large. The gap between the lower end of the bed body 2 and the side wall of the pit 511 away from the main pit 512 is also not large, so as to avoid the gap being too large and causing personnel to get stuck in the gap.

[0062] In this embodiment, the rotation adjustment device 3 includes an arc-shaped track structure 31 and a drive structure. The arc-shaped track structure 31 is mounted on the main body 1 of the diagnostic and treatment equipment. Please refer to [link to relevant documentation]. Figure 4 The diagram illustrates the arc-shaped track structure 31. The drive structure is connected to the arc-shaped track structure 31 and to the bed 2. Driven by the drive structure, the bed 2 can move along the arc-shaped track structure 31 into or out of the scanning hole 11, allowing the rotation adjustment device 3 to control the movement trajectory of the bed 2 to be arc-shaped. When the drive structure operates, it moves the bed 2 along the arc-shaped track structure 31; when the drive structure stops, it allows the bed 2 to remain on the arc-shaped track structure 31.

[0063] In addition, it should be noted that the rotation adjustment device 3 provided in this embodiment drives the bed body 2 to rotate. In order to avoid the bed body 2 interfering with the inner wall of the scanning hole 11 during the movement, the scanning hole 11 on the main body of the diagnostic and treatment equipment in this embodiment must have a certain size, which is suitable for the main body of the diagnostic and treatment equipment with a large aperture (≥80cm).

[0064] In this embodiment, the arc-shaped track structure 31 is integrated on the main body 1 of the diagnostic and treatment equipment, that is, the main body 1 of the diagnostic and treatment equipment serves to support the arc-shaped track structure 31, without the need to set up other special frames to support the arc-shaped track structure 31, thus simplifying the structure.

[0065] As mentioned above, in existing related technologies, when a patient is on the treatment bed, it often needs to move up and down, forward and backward, left and right to reach the treatment position of the main body of the diagnostic and treatment equipment, which leads to cumbersome position adjustment and cumbersome process for the patient to get on and off the treatment bed. In this embodiment, the drive structure drives the bed 2 to move along the arc-shaped track structure 31. That is, when the patient is on the bed 2 and the bed 2 moves to the treatment position of the main body of the diagnostic and treatment equipment 1, the bed 2 can rotate, which avoids the problem of cumbersome position adjustment of the treatment bed in existing related technologies.

[0066] Regarding the arc-shaped track structure 31, in one embodiment, the arc-shaped track structure 31 includes a front adjustment seat 311, a middle beam 312, and a rear adjustment seat 313. See also... Figure 4 The diagram shows the front adjustment seat 311, the middle beam 312, and the rear adjustment seat 313.

[0067] Please see Figure 1 The front adjustment seat 311 is shown; please refer to [link / reference]. Figure 2 The diagram illustrates the rear adjustment seat 313, meaning the front adjustment seat 311 and the rear adjustment seat 313 are respectively located on the front and rear sides of the main body 1 of the diagnostic and treatment device along the axis of the scanning hole 11. Please refer to... Figure 4 The intermediate beam 312 is mounted on the rotor 12. When the rotor 12 drives the intermediate beam 312 to rotate to a preset position, both ends of the intermediate beam 312 are aligned with the front adjusting seat 311 and the rear adjusting seat 313, respectively. The preset position refers to the position where the intermediate beam 312 rotates to a position where it can cooperate with the front adjusting seat 311 and the rear adjusting seat 313 to form an arc-shaped track. Please refer to [link to relevant documentation]. Figure 4 , Figure 4 The tops of the front adjustment seat 311, the middle beam 312, and the rear adjustment seat 313 are shown to form an arc shape.

[0068] The arc-shaped track structure 31 provided in this embodiment fully combines the structural characteristics of the main body 1 of the diagnostic and treatment equipment, so as to integrate the arc-shaped track structure 31 onto the main body 1 of the diagnostic and treatment equipment without affecting the normal diagnostic and treatment examination of the main body 1 of the diagnostic and treatment equipment.

[0069] Regarding the intermediate beam 312 being mounted on the rotor 12, in one specific example, the rotor 12 is provided with mounting grooves extending parallel to the axis of the rotor 12, and the mounting grooves respectively connect the front and rear end faces of the rotor 12. Preferably, please refer to... Figure 4 The top surface of the intermediate beam 312 does not protrude from the inner side of the scanning hole 11.

[0070] Please see Figure 3 and Figure 4 The drive structure includes a front drive structure 32 and a rear drive structure 33. When the bed body 2 is inserted into the scanning hole 11 and is in a horizontal state, the front drive structure 32 is connected to the front adjustment seat 311 and the rear drive structure 33 is connected to the rear adjustment seat 313.

[0071] Please see Figure 3 The front drive structure 32 and the rear drive structure 33 are located near the two ends of the bed body 2. In one example, the bed body 2 is directly connected to the front drive structure 32 and the rear drive structure 33; or, in another example, the bed body 2 is indirectly connected to the front drive structure 32 and the rear drive structure 33.

[0072] Assuming the initial state of the intermediate beam 312 is in a preset position, at this time, both ends of the intermediate beam 312 are aligned with the front adjusting seat 311 and the rear adjusting seat 313 respectively. Then, the front drive structure 32 and the rear drive structure 33 can be controlled to rotate, causing the front drive structure 32 and the rear drive structure 33 to drive the bed 2 to rotate until it reaches the desired position. Figure 5 As shown in the diagram, at this point, the rear drive structure 33 moves onto the intermediate beam 312, and the front drive structure 32 is positioned at the front adjustment seat 311. After a patient is placed on the bed 2, the front drive structure 32 and the rear drive structure 33 are then controlled to rotate the bed 2 in the opposite direction. Figure 4 As shown in the diagram, at this point, the rear drive structure 33 moves onto the rear adjustment seat 313, while the front drive structure 32 remains on the front adjustment seat 311. Since neither the front drive structure 32 nor the rear drive structure 33 is on the intermediate beam 312, the rotor 12 of the main body of the diagnostic and treatment equipment can be controlled to rotate to perform diagnostic examinations on the patient on the bed 2. After the examination is completed, the rotor 12 is rotated until the intermediate beam 312 is in a preset position, so that both ends of the intermediate beam 312 are aligned with the front adjustment seat 311 and the rear adjustment seat 313, respectively. Then, the front drive structure 32 and the rear drive structure 33 are controlled to drive the bed 2 to rotate until it reaches the desired position. Figure 5 As shown in the diagram, at this point, the patient can get off bed 2.

[0073] When the main body 1 of the diagnostic and treatment equipment is not in use, the front drive structure 32 and the rear drive structure 33 can be controlled to rotate the bed 2 to the desired position. Figure 4 The horizontal position shown is to save space.

[0074] In this embodiment, it is preferable that the front drive structure 32 and the rear drive structure 33 move synchronously on the arc-shaped track structure 31, so that the distance between the front drive structure 32 and the rear drive structure 33 along the length direction of the arc-shaped track structure 31 is always the same. Specifically, for example, when the bed 2 is located at Figure 5 When the position shown is reached, the front drive structure 32 and the rear drive structure 33 can be activated simultaneously, causing the front drive structure 32 and the rear drive structure 33 to drive the bed 2 to rotate and move in the direction of extending into the scanning hole 11, until the bed 2 rotates to the position shown. Figure 4 In the horizontal state shown, both the front drive structure 32 and the rear drive structure 33 can be turned off simultaneously. Of course, in one example, the actions of the front drive structure 32 and the rear drive structure 33 can also be controlled to be asynchronous, that is, the start and / or stop times of the front drive structure 32 are different from those of the rear drive structure 33.

[0075] In this embodiment, regarding switching the front drive structure 32 and rear drive structure 33 from the running state to the off state, in one example, a position detection device can be installed on the arc-shaped track structure 31. For example, when the bed 2 is in operation... Figure 5 Rotate to the position shown Figure 4 When the indicated position is reached, the position detection device detects the front drive structure 32 and the rear drive structure 33. The position detection device transmits a signal to the main control unit of the main body 1 of the diagnostic and treatment equipment, causing the main control unit to control the front drive structure 32 and the rear drive structure 33 to stop moving, so that the front drive structure 32 and the rear drive structure 33 remain at the indicated position. Figure 4 The position shown is indicated; similarly, when bed 2 is... Figure 4 Rotate to the position shown Figure 5 When the indicated position is reached, the position detection device detects the front drive structure 32 and the rear drive structure 33. The position detection device transmits a signal to the main control unit of the main body 1 of the diagnostic and treatment equipment, causing the main control unit to control the front drive structure 32 and the rear drive structure 33 to stop moving, so that the front drive structure 32 and the rear drive structure 33 remain at the indicated position. Figure 5 The indicated location. Or, in another example, see [link to example]. Figure 4 When the rear drive structure 33 moves to such a position Figure 4 When the position shown is reached, due to the shape limitation of the rear adjustment seat 313, the rear drive structure 33 can no longer move away from the intermediate beam 312. When the detection device detects that the rear drive structure 33 is not moving, it transmits a signal to the main control unit, which then controls the front drive structure 32 and the rear drive structure 33 to stop operating. Please refer to [link to relevant documentation]. Figure 5 The current drive structure 32 moves to such Figure 5 When the position shown is reached, the front drive structure 32 cannot continue to move away from the middle beam 312 due to the shape limitation of the front adjustment seat 311. When the detection device detects that the front drive structure 32 is not moving, it transmits a signal to the main control unit, which then controls the front drive structure 32 and the rear drive structure 33 to stop moving.

[0076] The arc-shaped track structure 31 and the drive structure provided in this embodiment enable the drive structure to rotate the bed body 2 along the arc-shaped track structure 31 to enter the scanning hole 11 without affecting the normal operation of the main body 1 of the diagnostic and treatment equipment.

[0077] Please see Figure 1 and Figure 2 In one embodiment, the arc length of the top surface of the front adjustment seat 311 is greater than the arc length of the top surface of the rear adjustment seat 313.

[0078] Since the bed body 2 drives out through the front adjustment seat 311, during the process of the front drive structure 32 and the rear drive structure 33 driving the bed body 2 to rotate into or out of the scanning hole 11, the front drive structure 32 is always located on the front adjustment seat 311. Therefore, the arc length of the top surface of the front adjustment seat 311 is set to be greater than the arc length of the top surface of the rear adjustment seat 313.

[0079] Regarding the front adjustment seat 311, in one example, please refer to Figure 1 The front adjustment seat 311 can be set to be located inside the bed body avoidance pit 511 and supported on the bottom surface of the bed body avoidance pit 511.

[0080] Regarding the shape of the front adjustment seat 311, see one example. Figure 1 The front adjustment seat 311 is generally fan-shaped, and includes a vertical side surface that contacts the main body 1 of the diagnostic and treatment equipment, and a horizontal bottom surface that contacts the bottom surface of the bed clearance pit 511. The arc-shaped side of the front adjustment seat 311 cooperates with the front drive structure 32. Preferably, the front adjustment seat 311 is fixed to the main body 1 of the diagnostic and treatment equipment, that is, the front adjustment seat 311 can be fixed to the frame slip ring 13 and / or the frame and support seat 14 of the main body 1 of the diagnostic and treatment equipment. Specifically, the front adjustment seat 311 can be welded to the main body 1 of the diagnostic and treatment equipment or detachably connected to the main body 1 of the diagnostic and treatment equipment.

[0081] For information on rear adjustment seat 313, please refer to [link / reference]. Figure 2 In one example, the rear adjustment seat 313 is fixed to the main body 1 of the diagnostic and treatment equipment, that is, the rear adjustment seat 313 is fixed to the frame slip ring 13 of the main body 1 of the diagnostic and treatment equipment; in another example, the rear adjustment seat 313 is fixed to the frame and support seat 14 of the main body 1 of the diagnostic and treatment equipment; or, the rear adjustment seat 313 may be set to be supported on the ground.

[0082] Regarding the shape of the rear adjustment seat 313, please refer to Figure 6 In one example, the rear adjustment seat 313 is fan-shaped.

[0083] In one embodiment, slide rails 315 are provided on the front adjusting seat 311, the intermediate beam 312, and the rear adjusting seat 313. The front drive structure 32 and the rear drive structure 33 both include sliders or rollers that cooperate with the slide rails 315. By providing slide rails 315 and sliders or rollers that cooperate with them, the front drive structure 32 and the rear drive structure 33 are guided, so that the bed 2 moves stably on the arc-shaped track structure 31 under the drive of the front drive structure 32 and the rear drive structure 33.

[0084] In this embodiment, when the slide rail 315 is engaged with the slider or roller, it can not only guide the front drive structure 32 and the rear drive structure 33 to move in the length extension direction of the slide rail 315, but also prevent the front drive structure 32 and the rear drive structure 33 from detaching from the arc track structure 31 along the radial direction of the arc track structure 31. That is, by engaging the slide rail 315 with the slider or slip ring, the front drive structure 32 and the rear drive structure 33 can be constrained on the arc track structure 31.

[0085] In a specific example, slide rail 315 is a cross roller slip ring track. In this case, cross roller slip rings are provided on the front drive structure 32 and the rear drive structure 33 to cooperate with the cross roller slip ring track.

[0086] In a specific example, please see Figure 6 and Figure 9 Two slide rails 315 are provided on the top surface of the front adjustment seat 311, the top surface of the rear adjustment seat 313, and the top surface of the middle beam 312. When the front adjustment seat 311 and the rear adjustment seat 313 are aligned with the middle beam 312, the slide rails 315 on the same side of the front adjustment seat 311 and the rear adjustment seat 313 are respectively aligned with the slide rails 315 on the corresponding side of the middle beam 312.

[0087] In one embodiment, please refer to Figure 5 and Figure 6 The top surfaces of the front adjustment seat 311, the intermediate beam 312 and the rear adjustment seat 313 are all provided with teeth 314, and the front drive structure 32 and the rear drive structure 33 both include gearboxes that mesh with the teeth 314.

[0088] The gearbox of the front drive structure 32 is the front gearbox 323, and the gearbox of the rear drive structure 33 is the rear gearbox 333. Please refer to [link / reference]. Figure 6 The diagram illustrates the front gearbox 323 and the rear gearbox 333. The front gearbox 323 and the rear gearbox 333 can have the same structure, and both the front gearbox 323 and the rear gearbox 333 include gears that mesh with the gear 314.

[0089] A gearbox is a mechanical transmission device, mainly composed of gears, shafts, bearings, and housing. It can realize functions such as speed change, torque change, and power transmission. This embodiment does not specifically limit the specific structure of the gearbox 323.

[0090] In an example where two slide rails 315 are provided on the top surface of the front adjustment seat 311, the top surface of the rear adjustment seat 313, and the top surface of the intermediate beam 312, the tooth 314 of the front adjustment seat 311 is located in the middle of the two slide rails 315 on the front adjustment seat 311, the tooth 314 of the rear adjustment seat 313 is located in the middle of the two slide rails 315 on the rear adjustment seat 313, and the tooth 314 of the intermediate beam 312 is located in the middle of the two slide rails 315 on the intermediate beam 312.

[0091] In one example, the teeth 314 on the front adjusting seat 311 extend along the length of the top surface of the front adjusting seat 311 to both ends of the front adjusting seat 311, or the bed body 2 is positioned as follows: Figure 5 The horizontal position shown is called the detection position. The position where the bed body 2 is close to the ground at one end is called the upper and lower bed position. The length of the teeth 314 on the front adjustment seat 311 along the top surface of the front adjustment seat 311 is only required to enable the front drive structure 32 to switch the bed body 2 between the detection position and the upper and lower bed position. It is not necessary for the teeth 314 on the front adjustment seat 311 to extend to both ends of the front adjustment seat 311 along the length direction of the top surface of the front adjustment seat 311.

[0092] Specifically, please see Figure 6 A limiting plate 3111 is provided at the end of the top surface of the front adjustment seat 311 away from the middle beam 312. The current drive structure 32 moves to such a position. Figure 5 When the position shown is reached, the front drive structure 32 can no longer move away from the intermediate beam 312 due to the restriction of the limiting plate 3111.

[0093] In one example, the teeth 314 on the rear adjustment seat 313 extend along the length of the top surface of the rear adjustment seat 313 to both ends of the rear adjustment seat 313, or, please refer to Figure 5 and Figure 6 The length of the teeth 314 on the rear adjustment seat 313 along the top surface of the rear adjustment seat 313 is only required to satisfy the requirement that the rear drive structure 33 drives the bed 2 to switch between the detection position and the upper and lower bed position. It is not necessary for the teeth 314 on the rear adjustment seat 313 to extend to both ends of the front adjustment seat 311 along the length direction of the top surface of the rear adjustment seat 313.

[0094] Specifically, please see Figure 4 and Figure 5 The rear adjustment seat 313 does not have a tooth 314 on the side away from the intermediate beam 312, so that when the rear drive structure 33 moves to such a position... Figure 4 When the position shown is the end position of the upper tooth 314 of the rear adjustment seat 313, the rear drive structure 33 can no longer move away from the intermediate beam 312.

[0095] In one example, see Figure 5 The teeth 314 on the intermediate beam 312 extend along the length of the top surface of the intermediate beam 312 to both ends of the intermediate beam 312. Alternatively, the teeth 314 on the intermediate beam 312 only need to be long enough for the rear drive structure 33 to drive the bed 2 to switch between the detection position and the upper and lower bed position. It is not necessary for the teeth 314 on the intermediate beam 312 to extend along the length of the top surface of the intermediate beam 312 to both ends of the intermediate beam 312.

[0096] In this embodiment, the front drive structure 32 and the rear drive structure 33 also have a locking function. The locking function is used to keep the front drive structure 32 and the rear drive structure 33 on the arc-shaped track structure 31. For example, when the bed 2 needs to stay on the arc-shaped track structure 31... Figure 4 The horizontal state shown is or Figure 5 When the tilted state is shown, it can be achieved through the locking function on the drive structure 32 and the rear drive structure 33, so as to stabilize the bed 2 on the arc track structure 31.

[0097] Regarding the locking function, in a specific example, both the front drive structure 32 and the rear drive structure 33 include drive motors; please refer to [link / reference needed]. Figure 6 The drive motor of the front drive structure 32 is a front drive motor 321, and the drive motor of the rear drive structure 33 is a rear drive motor 331. Both the front drive motor 321 and the rear drive motor 331 are brake motors, which can brake quickly when the motor stops running, thereby realizing the locking function of the front drive structure 32 and the rear drive structure 33. When the slide rail 315 cooperates with the slider or roller, the front drive structure 32 and the rear drive structure 33 can only move along the length extension direction of the slide rail 315. When the front drive motor 321 and the rear drive motor 331 are in the stopped state, the front gearbox 323 and the rear gearbox 333 do not rotate. The gears of the front gearbox 323 and the rear gearbox 333 mesh with the teeth 314 on the arc track structure 31, so that the front drive structure 32 and the rear drive structure 33 stay on the arc track structure 31, thereby stabilizing the bed 2 on the arc track structure 31.

[0098] Regarding brake motors, their working principle primarily relies on an electromagnetic braking device to brake the motor. A brake motor mainly consists of two parts: the motor body and the electromagnetic brake device. By switching between the energized and de-energized states of the motor body, the electromagnetic brake device brakes and releases the motor body, achieving purposes such as quickly stopping the motor and accurately controlling its position.

[0099] In one embodiment, the drive motors of the front drive structure 32 and the rear drive structure 33 are directly connected to their respective gearboxes. Alternatively, in another embodiment, both the front drive structure 32 and the rear drive structure 33 further include a reducer connected to the drive motor, and the reducer of the front drive structure 32 and the reducer of the rear drive structure 33 are respectively connected to their respective gearboxes, thereby achieving indirect connection between the drive motors of the front drive structure 32 and the rear drive structure 33 and their respective gearboxes.

[0100] The reducer of the front drive structure 32 is a front reduction gearbox 322, and the reducer of the rear drive structure 33 is a rear reduction gearbox 332. Please refer to [link / reference]. Figure 6The front drive motor 321 is connected to the front gearbox 323 via the front reduction gearbox 322, and the rear drive motor 331 is connected to the rear gearbox 333 via the rear reduction gearbox 332. In one specific embodiment, the front reduction gearbox 322 and the rear reduction gearbox 332 are worm gear reducers.

[0101] In this embodiment, the reducer can reduce the speed, making the system run more smoothly, and at the same time increase the torque, thereby meeting the demand for high torque.

[0102] The above embodiments describe that both the front drive structure 32 and the rear drive structure 33 include a drive motor, a reducer connected to the drive motor, and a gearbox. In another embodiment, both the front drive structure 32 and the rear drive structure 33 include an arc-shaped frameless motor, and the stator of the arc-shaped frameless motor is arranged along the length direction of the arc-shaped track structure 31.

[0103] A frameless arc motor consists of a stator and a mover. The stator, typically located outside the motor, contains coils or magnetic strips to generate a magnetic field. The mover, a moving component usually composed of magnets, is located inside the motor. The mover moves according to the direction of the magnetic field, generating mechanical motion and torque.

[0104] In this embodiment, the motor stator of the front drive structure 32 is referred to as the front motor stator 324, and the motor mover of the front drive structure 32 is referred to as the front motor mover 325; the motor stator of the rear drive structure 33 is referred to as the rear motor stator 334, and the motor mover of the rear drive structure 33 is referred to as the rear motor mover 335. Please refer to [link / reference]. Figure 7 The diagram shows the front motor stator 324, the front motor mover 325, the rear motor stator 334, and the rear motor mover 335.

[0105] The front motor stator 324 is mounted on the top surface of the front adjustment seat 311 and extends along the length of the top surface of the front adjustment seat 311; please refer to Figure 7 and Figure 8 This illustrates that the front motor stator 324 extends along the length of the top surface of the front adjustment seat 311. When the current drive structure 32 is started, the front motor mover 325 can move along the front motor stator 324.

[0106] The rear motor stator 334 is mounted on the top surface of the intermediate beam 312 and the rear adjusting seat 313. The rear motor stator 334 extends along the length of the top surface of the intermediate beam 312 and the rear adjusting seat 313. Please refer to [link / reference]. Figure 7 This illustrates that the rear motor stator 334 extends along the length of the top surface of the rear adjustment seat 313. When the current drive structure 32 is started, the rear motor mover 335 can move along the rear motor stator 334.

[0107] In this embodiment, both the front drive structure 32 and the rear drive structure 33 include an arc-shaped frameless motor, which simplifies the structure of the rotation adjustment device 3.

[0108] In one embodiment, the position adjustment mechanism further includes a linkage structure 4, through which the front adjustment seat 311 and the rear adjustment seat 313 are connected to the bed body 2. The linkage structure 4 is used to adjust the position of the bed body 2 relative to the main body 1 of the diagnostic and treatment equipment.

[0109] The linkage structure 4 is used to fine-tune the position of the bed 2 relative to the main body of the diagnostic and treatment equipment 1, improve the positioning efficiency and accuracy, and concentrate the treatment dose (such as radiation dose) very precisely on the tumor tissue, so as to minimize the damage to normal tissue caused by the ultra-high dose rate.

[0110] In this embodiment, the preferred linkage structure 4 can realize six-dimensional motion function, for example, when the bed is in such a state as Figure 4 In the horizontal state shown, the length direction of bed 2 is defined as the X-axis, the width direction of bed 2 as the Y-axis, and the height direction of bed 2 as the Z-axis. The linkage structure 4 can realize six-dimensional motion functions, that is, it can lift along the Z-axis, move horizontally left and right along the X-axis, and move horizontally forward and backward along the Y-axis. The central axis of bed 2 parallel to the X-axis is called the X-axis central axis, which can realize forward and backward flipping around the X-axis central axis. The central axis of bed 2 parallel to the Y-axis is called the Y-axis central axis, which can realize left and right flipping around the Y-axis central axis. The vertical axis passing through the center point of bed 2 and parallel to the Z-axis is called the Z-axis rotation axis, which can realize horizontal rotation around the Z-axis rotation axis.

[0111] For details on the structure of linkage 4, please refer to [link / reference]. Figures 6-8 In one embodiment, the linkage structure 4 includes a linear drive device 41, one end of which is hinged to the bed body 2, and the other end of which is hinged to the front drive structure 32 or the rear drive structure 33. Two or more linear drive devices 41 are connected to the front drive structure 32; two or more linear drive devices 41 are connected to the rear drive structure 33. That is, the bed body 2 is supported on the front drive structure 32 and the rear drive structure 33 by the linear drive devices 41.

[0112] Preferably, the linear drive device 41 can be a linear drive motor, a cylinder, or a hydraulic cylinder.

[0113] In one specific example, the front drive structure 32 is connected to one end of the bed 2 with three linear drive devices 41, and the rear drive structure 33 is connected to the other end of the bed 2 with three linear drive devices 41. The three linear drive devices 41 on the front drive structure 32 and the three linear drive devices 41 on the rear drive structure 33 are symmetrically arranged. In another specific example, please refer to... Figure 9In one specific example, the front drive structure 32 is connected to one end of the bed 2 with four linear drive devices 41, and the rear drive structure 33 is connected to one end of the bed 2 with two linear drive devices 41; in another specific example, the front drive structure 32 is connected to one end of the bed 2 with two linear drive devices 41, and the rear drive structure 33 is connected to one end of the bed 2 with four linear drive devices 41.

[0114] In this embodiment, a linear drive device 41 is used to connect the front drive structure 32 to the bed body 2 and the rear drive structure 33 to the bed body 2. This allows for precise adjustment of the bed body 2's position while maintaining a simple structure for the linkage structure 4. Furthermore, the linear drive device 41 supports the bed body 2 on the front drive structure 32 and the rear drive structure 33, allowing multiple hinge points to be formed on the bed body 2. The multi-point support of the bed board 2 ensures good overall rigidity, reducing the thickness of the bed board 2 while maintaining its rigidity. This reduces the attenuation of various radiations in the main body 1 of the diagnostic and treatment equipment, thereby improving the equipment's performance.

[0115] In one embodiment, please refer to Figure 6 An adjustable pedal 21 is provided at one end of the bed body 2 near the front adjustment seat 311, and the length of the adjustable pedal 21 is set along the width of the bed body 2.

[0116] Please see Figure 5 This illustrates that when the bed 2 is tilted, the adjustable pedal 21 is close to the ground. When the patient is getting on or off the bed 2, the patient can step on the adjustable pedal 21 to facilitate the patient's exertion of force to get on or off the bed 2.

[0117] Existing treatment beds are horizontal when patients get on and off, so patients need to use the baffle at the end of the bed to get on and off. However, the bed 2 provided in this embodiment is tilted when patients get on and off. If there is no adjustable footrest 21 to support the patient's feet, it will cause inconvenience for the patient to get on and off the bed 2 and to lie flat on the tilted bed 2.

[0118] In this embodiment, the adjustable pedal 21 is preferably positioned on the bed 2 along its length, allowing the placement of the adjustable pedal 21 on the bed 2 to be determined based on the patient's height and the target area location. The adjustable pedal 21 can be mechanically adjusted, or it can be equipped with a motor for electric adjustment.

[0119] Regarding the adjustable pedal 21 employing a mechanically adjustable position setting, please refer to a specific example. Figure 6 Multiple parallel, spaced-apart inserts 22 are provided on the bed frame 2, with the inserts 22 spaced apart along the length of the bed frame 2. An insertion groove is provided on the adjustable pedal 21. (See [reference]) Figure 6The adjustable pedal 21 can be pushed or pulled along the width direction of the bed 2 so that the adjustable pedal 21 is disengaged from the insert 22 on the bed 2. Select the appropriate position of the insert 22, insert one end of the insertion groove into the insert 22, and then push the adjustable pedal 21 so that the adjustable pedal 21 is connected to the bed 2 through the insertion groove of the insert 22.

[0120] Regarding bed 2, in one embodiment, please refer to Figure 6 Alternatively, a headboard baffle 23 can be installed at one end of the bed body 2 near the rear adjustment seat 313. Or, to avoid interference with the scanning hole 11, the headboard baffle 23 can be removed from the bed body 2.

[0121] In one embodiment, handrails 24 are provided on both sides of the bed 2 along the width direction. By providing handrails 24, the patient can hold the handrails 24 when getting on and off the bed 2, so as to facilitate the patient's getting on and off the bed 2.

[0122] In one embodiment, the axis of rotation of the bed 2 when it rotates along the arc track structure 31 is perpendicular to the axis of the scanning hole 11; when the bed 2 rotates to a horizontal state, the center of the bed 2 coincides with the center of the scanning surface and the center of the treatment surface of the main body of the diagnostic and treatment device 1.

[0123] The treatment device on the main body 1 of the diagnostic and treatment equipment forms a treatment surface as the rotor 12 rotates one revolution. See [link / reference]. Figure 10 , Figure 10 The diagram illustrates the diagnostic closure curve B, and the area enclosed by curve B represents the diagnostic surface. The scanning device on the main body 1 of the diagnostic equipment forms a scanning surface as the rotor 12 rotates one revolution. (See [reference]). Figure 10 , Figure 10 The diagram illustrates the closed scanning curve A, and the area enclosed by the closed scanning curve A represents the scanning surface; Figure 10 The middle bed plane E represents the state when the bed 2 is in a horizontal position; the motion trajectory of the bed 2 will fall on the rotational motion line C, and the plane containing the rotational motion line C is perpendicular to the diagnostic and scanning planes. The plane containing the bed plane E is also perpendicular to the diagnostic and scanning planes. The center of the diagnostic and scanning planes is the isocenter D of the equipment. That is, when the bed 2 rotates to such a position... Figure 4 In the horizontal state shown, the center of bed 2 (i.e., the center of bed plane E) coincides with the center D of the equipment.

[0124] In this embodiment, by limiting the rotation of the bed 2 to such a position... Figure 4 When the bed is in the horizontal position as shown, the center of the bed 2 (i.e. the center of the bed plane E) coincides with the center of the equipment D, which can improve the positioning efficiency of the bed 2.

[0125] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
