Description

Technical Field

[0001] This utility model relates to the field of X-ray imaging, and in particular to an X-ray vertical radiography stand and an X-ray imaging system. Background Technology

[0002] DR (Digital Radiography) is an X-ray imaging device that typically includes a head assembly and a detector assembly. The head assembly contains the X-ray source, and the X-rays emitted by the X-ray source are collected by the detector assembly after passing through an object.

[0003] DR products often use a film cassette as a detection component, which can be raised, lowered, or flipped on a vertical stand. To meet different imaging needs, the operator generally needs to operate the film cassette to move up and down and / or flip along the vertical stand.

[0004] In related technologies, the film cartridge can be adjusted in the above-mentioned position using either a purely electric or purely manual method. However, purely manual operation requires considerable force, which is inconvenient for the operator; while purely electric operation is less strenuous, it generally requires button control, and the movement speed is fixed, making it difficult to control the movement distance, thus also presenting the problem of inconvenient adjustment.

[0059] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0060] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0062] In the embodiment of the X-ray vertical radiography gantry of this application, a sensor 400 is provided between the operating component 300 for driving the film cassette 200 to rise and fall and the film cassette 200. The sensor 400 can map the operating force received by the operating component 300 along the rising and falling direction. In conjunction with the electric assist controller 500 and the lifting drive device, the film cassette 200 can be electrically assisted to rise and fall. The operator only needs to apply a small force to the operating component 300 and give the intention of the rising and falling operation, and the rising and falling operation can be achieved relatively easily with electric assistance, making the operation more convenient.

[0063] Embodiments of the X-ray vertical imaging gantry in this application:

[0064] To more clearly illustrate the specific embodiments of this utility model, the following will use the term... Figure 1 The directions shown are described as up, down, left, right, front, and back. Of course, the use of these directions in the embodiments is merely an example to more clearly illustrate the positional relationship between the various components, and does not limit the embodiments of this utility model to be arranged in this way.

[0065] Please refer to Figure 1 and Figure 2 In one embodiment, the X-ray vertical imaging gantry includes a vertical support 100 and a film cassette 200, wherein the vertical support 100 is used to support the film cassette 200, and the film cassette 200 is used to install an X-ray detection module.

[0066] Those skilled in the art will understand that after the X-ray emitting device in an X-ray imaging system emits X-rays, the X-ray detection module is used to receive the X-rays after they have passed through the object being examined, thereby enabling imaging. The X-ray detection module can be a flat panel detector, a common component of X-ray imaging systems. It captures X-rays and converts them into image signals, which can then be processed into image data for real-time viewing on a computer. The flat panel detector can transmit signals wirelessly or via a wired connection. The film cassette 200 is a device for housing the X-ray detection module. During use, the flat panel detector can be fixed inside the film cassette 200 and its position can be adjusted with the film cassette 200 to meet different imaging needs. The X-ray detection module can also use a traditional film cassette 200 for direct imaging via film. The X-ray detection module can be part of an X-ray vertical radiography gantry or can be installed on the gantry during use.

[0067] It should be noted that the specific structures of the aforementioned film cassette 200 and X-ray detection module can refer to existing structures in related technologies. Considering that they are not directly related to the innovative content and technical problem to be solved in this application, they will not be elaborated upon here. Furthermore, the type of X-ray detection module is not limited, as long as it can achieve X-ray detection and imaging.

[0068] In one embodiment, such as Figure 1 The vertical support 100 may include a base 110 and a column 111. The base 110 is used to support the installation on a foundation, such as a room floor, to ensure the stable placement of the vertical support 100. The column 111 can be fixed to the base 110 so that the film box 200 can be supported at a set height.

[0069] To achieve height adjustment of the film cassette 200, a lifting guide rail extending vertically can be installed on the vertical support 100. A lifting component is mounted on the lifting guide rail, comprising a connecting seat 112 and the aforementioned film cassette 200. The connecting seat 112 connects to the film cassette 200 and can move up and down along the lifting guide rail, thus achieving the lifting of the film cassette 200. In some other embodiments, the lifting component may also be composed solely of the film cassette 200; additionally, the lifting component may include other structures, such as a lateral movement component for enabling the film cassette 200 to be adjusted horizontally. The lifting power for the film cassette 200 can be provided by a lifting drive device. The structure of the lifting drive device is not limited; for example, please refer to... Figure 3 In some embodiments, a lifting drive motor 121 and a drive pulley can be installed at the upper end of the vertical support 100. A synchronous belt can be wound around the drive pulley, and the synchronous belt is connected to the connecting seat 112. By driving the drive pulley to rotate through the lifting drive motor 121, and then driving the synchronous belt to move, the lifting of the connecting seat 112 and the film box 200 can be realized. The transmission mechanism between the lifting drive motor 121 and the drive pulley is not limited. For example, it can be driven by a belt drive structure, which facilitates the side-by-side arrangement of the lifting drive motor 121 and the drive pulley, and helps to save space. A counterweight can be connected to the synchronous belt, with the counterweight located on the left and right sides of the drive pulley, which can balance the weight of the film box 200, thus helping to reduce the driving power of the lifting drive device. The specific structure of the above-mentioned lifting drive device can refer to the existing structure in related technologies. Considering that it is not directly related to the innovative content and technical problem to be solved in this application, it will not be described in detail here.

[0070] To control the lifting and lowering of the film cassette 200, the X-ray vertical gantry also includes an operating component 300. Please refer to... Figure 2 , Figure 5 , Figure 6 The operating component 300 can be an operating handle. In one specific embodiment, the operating handle can be a ring handle with a gripping hole 310 for finger insertion. The rear part of the operating handle forms a gripping part for the operator to hold, allowing the operator to grasp the gripping part of the operating handle to adjust the height of the disc tray 200, making it convenient to use. In some other embodiments, the operating component 300 can also have other structural forms, such as an L-shaped handle structure, or a block-shaped or columnar structure that can be pinched by the operator.

[0071] For the electrically assisted drive cartridge 200, a sensor 400 is required to detect the operating force on the operating component 300. The sensor 400 can be positioned between the operating component 300 and the lifting component, mapping the operating force on the operating component 300 along the lifting direction. For example, the sensor 400 can be positioned between the operating component 300 and the cartridge 200, facilitating intuitive operation of the cartridge 200 and enabling tilting and / or lateral movement assistance. Alternatively, the sensor 400 can also be positioned between the operating component 300 and the connecting base 112.

[0072] The type of sensor 400 is not limited, as long as it can map the operating force received by the operating component 300 along the lifting direction. In some embodiments, the sensor 400 can be at least one of a force sensor, a displacement sensor, and a distance sensor. For example, the sensor 400 can be a force sensor to directly detect the magnitude and direction of the operating force. Alternatively, the sensor 400 can be a displacement sensor, which is mainly used to detect the relative position change of an object relative to a reference point. For example, it can be an inductive displacement sensor, a capacitive displacement sensor, a photoelectric displacement sensor, a laser displacement sensor, etc. The physical quantity detected by the displacement sensor is displacement. However, the direction and magnitude of the displacement can correspond to the direction and magnitude of the operating force received by the operating component 300. For example, the operating component 300 can be fixed to the tray 200. When the operating component 300 is subjected to force, the connection between the operating component 300 and the tray 200 will undergo elastic deformation under the action of the force, allowing the operating component 300 to swing relative to the tray 200. By detecting the displacement formed by the swing, the operating force received by the operating component 300 can be mapped. Sensor 400 can also be a ranging sensor, which is used to measure the distance between itself and the target object. For example, it can be an ultrasonic ranging sensor, an infrared ranging sensor, etc. It can also be used to map the direction and magnitude of the operating force on the operating component 300.

[0073] In one embodiment, the sensor 400 may employ, for example... Figure 12 , Figure 13 The force sensor 400 shown is a two-dimensional force sensor. It includes a first fixing part 411 and a second fixing part 412, which are fixedly connected to the film cassette 200 and the operating component 300, respectively. The operating component 300 is fixed to the film cassette 200 via the two-dimensional force sensor. By employing a two-dimensional force sensor, when the film cassette 200 has two different postures, the sensor can map the operating force received by the operating component 300 along the lifting direction when the film cassette 200 is in different postures, thus facilitating adaptation to situations with two different postures.

[0074] For example, a film cassette 200 extending in the left-right direction can be provided between the film cassette 200 and the connecting seat 112. The film cassette ...

[0075] As an example, when the sensor plane of the cartridge 200 is parallel to the lifting and lowering direction of the cartridge 200, the two-dimensional force sensor can have a first detection dimension along the lifting and lowering direction of the cartridge 200, and a second detection dimension perpendicular to the lifting and lowering direction of the cartridge 200 and perpendicular to the sensor plane. Thus, using the first detection dimension of the two-dimensional force sensor along the lifting and lowering direction of the cartridge 200, when the sensor plane is closer to a vertical orientation, the operating force experienced by the operating component 300 along the lifting and lowering direction can be mapped; similarly, using the second detection dimension of the two-dimensional force sensor along the lifting and lowering direction of the cartridge 200, when the sensor plane is closer to a horizontal orientation, the operating force experienced by the operating component 300 along the lifting and lowering direction can also be mapped. Those skilled in the art will understand that for a cartridge 200 with a fixed orientation, the sensor 400 used to achieve electric assist can also be a one-dimensional sensor 400, used only to detect the lifting and lowering operating force along the vertical direction. In some other embodiments, sensor 400 may also be a multidimensional sensor, which is used to map the operating force on the operating component along three different directions, at least one of which is the lifting direction. In this case, as an example, sensor 400 may be used to detect the lifting operating force, the flipping operating force, and the lateral operating force on the cassette 200.

[0076] One of the first fixing part 411 and the second fixing part 412 is an inner fixing part, and the other is an outer fixing part surrounding the outer periphery of the inner fixing part. For example, the first fixing part 411 is an outer fixing part, and the second fixing part 412 is an inner fixing part. The two-dimensional force sensor also includes a first connecting part 421, a second connecting part 422, a third connecting part 423, and a fourth connecting part 424 connecting the inner fixing part and the outer fixing part. The distribution direction of the first connecting part 421 and the second connecting part 422 intersects the distribution direction of the third connecting part 423 and the fourth connecting part 424, for example, according to... Figure 12 , Figure 13The diagram shows a perpendicular intersection. Of course, in some other embodiments, the intersection angle can be adjusted as needed. By providing the first connecting part 421, the second connecting part 422, the third connecting part 423, and the fourth connecting part 424, the force can be transmitted more stably between the first fixing part 411 and the second fixing part 412, resulting in better load-bearing capacity and higher reliability for the sensor 400. In some embodiments, the distribution direction of the first connecting part 421 and the second connecting part 422 is parallel to the lifting direction, facilitating the design of the force detection algorithm.

[0077] The sensor 400 can be connected to the cartridge 200 and the operating component 300 via threaded fasteners. In one embodiment, the outer fixing part formed by the first fixing part 411 has two threaded holes 4111, and the inner fixing part formed by the second fixing part 412 has two screw through holes 4121; correspondingly, the front part of the operating component 300 has two threaded connection holes (obscured in the figure), which correspond one-to-one with the screw through holes 4121 on the inner fixing part in the front-back direction, while the back panel 230 of the cartridge 200 has two connecting through holes 2111 (e.g., ...). Figure 11 The connecting through hole 2111 is used to correspond one-to-one with the two threaded holes 4111 on the outer fixing part in the front-back direction. In a specific embodiment, the rear panel 230 on the rear side of the chip box 200 is provided with a mounting port 231 for mounting the operating component 300. The front side of the rear panel 230 is provided with a mounting support 210. The mounting support 210 includes a mounting plate 211 parallel to the rear panel 230 and a connecting plate 212 connecting the left and right sides of the connecting plate 212 between the rear panel 230 and the connecting plate 212. The connecting through hole 2111 is provided on the mounting plate 211. The mounting plate 211 and the two connecting plates 212 of the mounting support 210 can form a receiving cavity to accommodate the sensor 400. The structure is compact and helps to avoid excessive protrusion of the operating component 300.

[0078] When installing sensor 400 and operating component 300, please refer to Figures 9 to 11 First, two fixing screws 440 can be passed through the two screw holes 4121 on the inner fixing part of the sensor 400 and threaded into the two threaded connection holes at the front of the operating component 300 to achieve a fixed connection between the sensor 400 and the operating component 300. Then, two more fixing screws 440 can be passed through the connection through hole 2111 on the chip box 200 and threaded into the threaded hole 4111 on the outer fixing part to achieve a fixed connection between the sensor 400 and the chip box 200.

[0079] Those skilled in the art will understand that the specific structure of the sensor 400 described above can refer to existing structures in related technologies. Considering that it is not directly related to the innovative content and technical problem to be solved in this application, it will not be elaborated further here. Of course, for other types of sensors besides the force sensor 400, different detection dimensions can be set as needed to meet different detection requirements. Furthermore, the specific fixing structure between the sensor 400, the operating component 300, and the cartridge 200 can be flexibly selected according to the shape of the sensor 400. In some other embodiments, the sensor 400 may only be used to detect physical quantities such as operating force, without needing to transmit force between the cartridge 200 and the operating component 300.

[0080] Force sensors 400 generally have a limited measurement range, or range limitation. If the force on the sensor 400 exceeds its measurement range, it may be damaged. Furthermore, due to the small size of the sensor 400, the stress is concentrated at the connection points between the sensor 400 and the chip holder 200 and the operating component 300. Excessive force on the operating component 300 may damage the operating component 300 and / or the chip holder 200. Therefore, a limiting structure can be provided between the chip holder 200 and the operating component 300 to limit the maximum displacement of the operating component 300 relative to the chip holder 200. This maximum displacement can be set such that when the operating component 300 reaches its maximum displacement relative to the chip holder 200, the sensor 400 has not yet exceeded its measurement range, thus protecting the sensor 400, the chip holder 200, and the operating component 300.

[0081] In some embodiments, the limiting structure may include a first limiting member 220 and a second limiting member 320. The first limiting member 220 is disposed on the tablet cassette 200, and the second limiting member 320 is disposed on the operating member 300. The first limiting member 220 and the second limiting member 320 are used to limit the amount of deflection of the operating member 300 relative to the tablet cassette 200. One of the first limiting member 220 and the second limiting member 320 has a limiting cavity 321, and the other has a limiting post. The limiting post is movably disposed within the limiting cavity 321, and at least one side wall of the limiting post is spaced apart from a corresponding side wall of the limiting cavity 321. The space is used to limit the relative amount of deflection between the first limiting member 220 and the second limiting member 320. By using the form of a matching limiting post and limiting cavity 321, the limiting structure can achieve limiting in different directions with a small size, resulting in a compact structure.

[0082] In one specific embodiment, the operating component 300 is provided with a lug for forming a second limiting member 320. The lug has a through hole, and the limiting cavity 321 is formed by the through hole. Simultaneously, the left and right connecting plates 212 of the mounting support 210 are provided with screw connection holes 2121. A limiting screw serving as the first limiting member 220 is threaded into the screw connection hole 2121. The shank of the limiting screw has an extended portion that protrudes from the screw connection hole 2121, forming a limiting post with one end fixed and the other end suspended. The installation structure is simple and easy to assemble and disassemble. When an upward or downward force is applied to the operating component 300, as the sensor 400 deforms under the force, the operating component 300 can produce a small swing around the axis extending in the left-right direction. The sidewalls on both sides of the through hole can limit the excessive movement of the limiting screw in the front-back direction, thereby playing a limiting role and preventing the sensor 400 from being subjected to excessive force.

[0083] In some other embodiments, the limiting structure can also be replaced with other forms. For example, support portions that are opposite each other in the front-rear direction can be provided on the operating component 300 and the tablet cassette 200. When the operating component 300 swings a large distance, the support portions on the operating component 300 can abut against the support portions on the tablet cassette 200, thereby limiting further swing of the operating component 300.

[0084] The X-ray vertical imaging gantry also includes an electric assist controller 500, which is connected to the sensor 400 and the lifting drive device. The electric assist controller 500 is used to electrically assist the lifting of the film cassette 200. Those skilled in the art should understand that, optionally, the electric assist controller 500 can detect the operating force signal transmitted by the sensor 400 and control the lifting drive device to drive the film cassette 200 to lift at the appropriate speed based on the magnitude of the operating force. The electric assist controller 500 can be a standalone circuit module or integrated into other circuit modules. The specific structure of the electric assist controller 500 can be referenced from existing structures in related technologies; however, considering that it is not directly related to the innovative content and technical problem to be solved in this application, it will not be described in detail here. The placement of the electric assist controller 500 is not limited; for example, as an example, it can be placed at the bottom of the vertical support 100, or at the top of the support column 111.

[0085] In some embodiments, for the flip-up film cassette 200, the X-ray vertical gantry may further include a flip-up drive device for driving the film cassette 200 to flip. Correspondingly, the sensor 400 can map the operating force, i.e., the flipping force, experienced by the operating component 300 along the flipping direction of the film cassette 200. The electric assist controller 500 is electrically assisted connected to the sensor 400 and the flip-up drive device, enabling the electric assist flipping of the film cassette 200. The specific structure of the flip-up drive device is not limited. For example, a flip-up drive motor 141 can be used to drive the driving gear 142, which in turn drives the driven gear 143 fixed on the film cassette 200 to rotate, thereby achieving the flipping drive of the film cassette 200 through gear transmission.

[0086] The X-ray imaging system will be placed on the left or right depending on the usage environment. One side of the film cassette 200 may be located against a wall or in a position where it is inconvenient for the doctor to stand, which will make it inconvenient for the doctor to use.

[0087] To solve this problem, it is advisable to provide a first operating position 241 and a second operating position 242 on the left and right sides of the disc tray 200, respectively (see reference). Figure 5 Both the first operating position 241 and the second operating position 242 are provided with mounting structures for installing the operating component 300. The operator can choose to install the operating component 300 on the left or right side of the rear side of the film cassette 200. The operating component 300 can be pre-installed at the factory according to the customer's specified location, allowing for convenient operation. Alternatively, it can be installed on-site, with the installation location determined by the site conditions. In some other embodiments, the operating component 300 can be installed simultaneously on both the left and right sides of the rear side of the film cassette 200. Furthermore, the operating component 300 can be positioned on the left and right sides of the film cassette 200. Those skilled in the art will understand that providing the first operating position 241 and the second operating position 242 for selective installation of the operating component 300, requiring only one operating component 300, helps save costs.

[0088] In some cases, along the arrangement direction of the first operating position 241 and the second operating position 242, i.e., the left-right direction in the figure, one side of the operating component 300 is the control side 340, and the control side 340 is provided with a button 341 for the operator to operate. When the operating component 300 is selectively installed on the first operating position 241 and the second operating position 242, if the operating component 300 adopts the same posture, the control side 340 will face the direction opposite to the mounting side of the operating component 300 on one of the operating positions, which is not conducive to the operator observing the button 341 on the control side 340. Therefore, in some embodiments, the limiting post is detachably fixed to the film cassette or the operating component 300. One of the film cassette 200 and the operating component 300 has at least two mounting positions for fixing the limiting post. When the operating component 300 is connected to the film cassette 200 in two inverted postures, the limiting cavity on the other of the film cassette 200 and the operating component 300 can accommodate the insertion of the limiting post fixed in different mounting positions. In the above embodiments, the limiting post is formed by a limiting screw, and the limiting screw is detachably installed through a threaded connection. In some other embodiments, the limiting post can also be detachably installed in other ways, for example, the limiting post can be inserted into a fixing hole, and a positioning pin is provided on the wall of the fixing hole, so that the limiting post can be detachably installed by means of the positioning pin.

[0089] Please refer to Figure 9 and Figure 11In one specific embodiment, the lug on the operating component 300 is offset to one side in the left-right direction, which can shorten the lever arm and allow the limiting post to withstand greater force. However, if the operating component 300 is inverted, the left-right offset direction of the lug will change, and the limiting screw, which is originally positioned as the first limiting member 220, will not be able to pass through the limiting cavity 321 on the lug due to length limitations. To address this, each of the two connecting plates 212 is provided with a screw connection hole 2121, forming one mounting position, for a total of two mounting positions. At this time, although the left-right offset direction of the lug will change when the operating component 300 is inverted, the limiting screw can also be simultaneously adjusted to the other mounting position. Furthermore, since the lug constituting the second limiting member 320 has two parts, one above the other, forming two limiting cavities 321, it can be ensured that the limiting screw connected to the screw connection hole 2121 on the right side can still pass through the limiting cavity 321 on the inverted operating component 300. Of course, in some other embodiments, the lug can also be located in the middle of the left and right direction of the operating component 300. No matter which screw connection hole 2121 the limiting screw, which is the first limiting member 220, is connected to, it can be inserted into the limiting cavity 321. In addition, in some other embodiments, the limiting screw can be of a longer length, so that after the operating component 300 is turned upside down, the limiting screw, which is the first limiting member 220, can still cooperate with the limiting cavity 321 on the lug, which is the second limiting member 320, to play a limiting role. In this case, only one mounting position for fixing the limiting post needs to be provided on the cartridge.

[0090] In some other embodiments, Figure 11 The screw connection hole 2121, located at the upper right of the mounting bracket 210, can also be located at the lower right of the mounting bracket 210. In this case, only the screw hole 2121 can be retained. Figure 11 The lug located above the operating component 300 serves to form the second limiting member 320. Of course, in some other embodiments, more mounting positions may be provided to fix the limiting post.

[0091] In some other embodiments, the limiting post can also be disposed on the second limiting member 320, and the limiting cavity can be disposed on the first limiting member 220. In this case, to ensure that the control side 340 and button 341 face left when the operating component 300 is installed on the left side of the first operating position 241, and that the control side 340 and button 341 face right when the operating component 300 is installed on the right side of the second operating position 242, a second limiting member 320 for fixing the limiting post can be disposed on the upper and lower sides of the operating component 300, and a limiting cavity can be disposed on the first limiting member 220 on the disc tray 200. Furthermore, only one first limiting member 220 can be disposed, for example, […]. Figure 11 The screw connection hole 2121 located on the left side is replaced with a limiting cavity.

[0092] Because the film cassette 200 uses electric assistance, if the operating component 300 is accidentally touched during use, even a small impact force could cause the film cassette 200 to move unexpectedly. To avoid this problem, in some embodiments, the operating component 300 is an operating handle with a grip for the operator to hold; the X-ray vertical gantry includes an unlock switch, which is triggered when the operator holds the grip to activate the electric assistance function. By setting the unlock switch, the electric assistance function is in the off state when the operator is not holding the grip, so even if the operating component 300 is accidentally touched, the electric assistance will not engage and cause the film cassette 200 to move unexpectedly, resulting in more reliable performance and better safety.

[0093] The type of unlocking switch is not limited; for example, it can be a motion-activated switch or a mechanical switch. In one specific embodiment, please refer to... Figure 14 and Figure 15 The unlocking switch can be a capacitive sensing switch, which includes a capacitor wire 351 disposed within the grip portion, which is made of insulating material. When the operator grips the grip portion, the environment around the capacitor wire 351 changes, and the corresponding circuit can detect this change, thereby generating a trigger signal. The principle of the capacitive sensing switch is prior art and will not be described in detail in this application. Those skilled in the art will understand that the capacitor wire 351 can be an ordinary wire and can be connected to the circuit within the cartridge 200 via a connector 352.

[0094] The operating handle is a hollow shell with an annular wall forming the grip hole 310. The capacitor line 351 is close to the side of the annular wall away from the grip hole 310. This way, when the operator holds the grip, the fingers can be closer to the capacitor line 351, which helps to ensure detection sensitivity.

[0095] To ensure the stable operation of the capacitive sensing switch, a wire positioning structure 361 is provided inside the operating handle. The capacitor wire 351 is fixed inside the operating handle through the wire positioning structure 361. This helps to ensure the consistency of the assembly position of the capacitor wire 351, so that the capacitive sensing switch can be reliably triggered according to the design parameters. Figure 14In the diagram, only the main body of the handle is shown, omitting the cover that encloses it, to illustrate the installation structure of the capacitor wire 351. The upper, rear, and lower parts of the handle body have grooves 362. Two raised ribs are located at the bottom of the rear groove 362, forming a positioning groove for the capacitor wire 351 to be embedded. This positioning groove constitutes a wire positioning structure 361, providing stable positioning for the capacitor wire 351. To further improve the positioning reliability of the capacitor wire 351, after it is embedded in the positioning groove, adhesive can be applied to the groove to bond and fix it to the handle. Alternatively, in some other embodiments, snap-fit ​​protrusions can be provided on the inner wall of the positioning groove to prevent the capacitor wire 351 from detaching from the groove.

[0096] In some other embodiments, the wire positioning structure 361 may also take other forms. For example, a positioning rib with a snap-fit ​​cavity may be provided on the handle body. The surface of the positioning rib may be perpendicular to the extension direction of the capacitor line 351. Multiple positioning ribs may be arranged at intervals along the extension direction of the capacitor line 351.

[0097] In use, when the film cassette 200 needs to be raised or lowered, the operator first grasps the grip part of the operating component 300 to trigger the capacitive sensing switch, at which point the electric power function is activated. Then, according to the target lifting and adjustment direction, an operating force is applied to the operating component 300 in the corresponding direction. The sensor 400 detects this operating force, and the electric power controller 500 controls the lifting drive device to generate a corresponding driving action based on the operating force signal. The lifting drive device executes the lifting and driving action at a corresponding speed, thereby realizing the electric-assisted lifting and lowering of the film cassette 200. Similarly, when the film cassette 200 needs to be flipped, the operator applies a flipping operating force to the operating component 300 in the corresponding direction according to the target lifting and adjustment direction. The sensor 400 detects this operating force, and the electric power controller 500 controls the flipping drive device to generate a corresponding driving action based on the operating force signal. The flipping drive device executes the flipping and driving action at a corresponding speed, thereby realizing the electric-assisted flipping of the film cassette 200.

[0098] By installing a sensor 400 and an electric assist controller 500 on the X-ray vertical radiography gantry, the film cassette 200 of the X-ray vertical radiography gantry can achieve electric assist lifting, which helps to reduce the intensity of operation, conveniently and accurately control the lifting speed, and more efficiently complete the position adjustment of the film cassette 200, which helps to improve the speed of X-ray detection.
