[0052] To more clearly illustrate the technical solutions in the embodiments of this application or related technologies, a clear and complete description will be provided below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0053] Interventional diagnostic and treatment techniques are widely used in clinical practice. As a crucial component of interventional diagnostic and treatment techniques, the catheterization bed plays a vital role in their clinical application. Therefore, improving the performance of the catheterization bed directly impacts the application and development of interventional diagnostic and treatment techniques. Furthermore, the catheterization bed is widely used clinically, primarily to support the patient lying flat on a bed surface. To facilitate clear visualization of the lesion by the surgeon, the position and angle of the bed need to be adjusted according to the surgical requirements. Because the catheterization bed contains numerous cables, these cables can easily interfere with the bed's movement during adjustments.

[0054] Regarding the above situation, firstly, please refer to [link / reference needed]. Figure 1 This application proposes a catheter bed 1, including a base 10, a bed board 20, a first transmission assembly 30 and a first drive component 40. The base 10 provides an installation foundation and setting space for the bed board 20. The catheter bed 1 can be placed on the bottom surface or a support platform through the base 10.

[0055] like Figures 1-3 As shown, the bed board 20 is located above the base 10 and is movably connected to the base 10; the first transmission assembly 30 includes a first transmission member 31 and a second transmission member 32 that is movably connected to the first transmission member 31. The first transmission member 31 is connected to the base 10, and the second transmission member 32 is connected to the bed board 20; the first driving member 40 is disposed on the bed board 20 and is movably connected to the second transmission member 32. The first driving member 40 is used to drive the second transmission member 32 to move, so that the second transmission member 32, under the relative action of the first transmission member 31, drives the bed board 20 to swing relative to the base 10 in the first swing direction M.

[0056] Specifically, the bed board 20 is slidably connected to the base 10 via the first transmission assembly 30, allowing the bed board 20 to be flexibly adjusted in position according to treatment needs, thus improving the ease of operation. The first driving component 40 is mounted on the bed board 20 and drives the second transmission component 32 via a transmission connection. This arrangement reduces interference from the structural components on the bed board 20's swing, improving the stability and flexibility of the catheterization bed 1 during adjustment. The first transmission component 31 can be fixed to the base 10, and the first driving component 40 drives the second transmission component 32 to move relative to the first transmission component 31. Since the first transmission component 31 is fixedly connected to the base 10, it can apply a reaction force to the second transmission component 32, causing the second transmission component 32 to drive the bed board 20 to swing relative to the base 10 along the first swing direction M.

[0057] It should be noted that there is relative movement between the bed board 20 and the base 10. When the first drive member 40 is mounted on the bed board 20, the circuit components on the bed board 20 can be directly electrically connected to the first drive member 40 via cables. This allows the first drive member 40 and the cables on the bed board 20 to swing together with the bed board 20, thereby avoiding interference from the cables and other components on the bed board 20. In some embodiments, a switch button for controlling the swing of the bed board 20 can be provided on the bed board 20 of the catheter bed 1. The switch button is electrically connected to the first drive member 40, so that the opening and closing of the first drive member 40 can control the opening and closing of the second transmission member 32, thereby controlling the swing of the bed board 20. The switch button needs to be electrically connected to the first drive component 40 via wiring. Since the switch button is located on the bed board 20, it can swing along with the bed board 20, thus avoiding interference with the wiring of the switch button due to the swing of the bed board 20. In other words, by placing the first drive component 40 and the second transmission component 32 on the bed board 20, this embodiment optimizes the cable layout, ensuring that the cables can swing synchronously with the bed board 20. This effectively prevents the cables on the bed board 20 from getting tangled or pulled by the swing of the bed board 20, further improving the reliability and safety of the catheter bed 1. Furthermore, to further optimize cable management, this embodiment can also add a cable storage groove to the bed board 20, allowing the cables to remain orderly as they move with the bed board 20, thus avoiding interference with the movement of the bed board 20. For example, the cable storage groove can be located at the bottom of the bed board 20 or on its periphery, which not only makes full use of the installation space on the bed board 20 but also reduces the impact of the cable storage groove on the overall appearance.

[0058] In this embodiment, the specific type of the first transmission component 30 is not specifically limited. For example, the first transmission component 30 can be a gear drive or a chain drive to ensure high transmission efficiency; alternatively, the first transmission component 30 can also be a hydraulic drive, using a hydraulic cylinder to achieve precise control and further improve the adjustment accuracy and stability of the bed plate 20; or, the first transmission component 30 can also be an electromagnetic drive, using electromagnetic force to achieve rapid response and precise control, reducing mechanical wear and extending the service life of the equipment. Furthermore, the working principle of the first drive component 40 can be motor drive, servo drive, or pneumatic drive, and is not specifically limited here.

[0059] Furthermore, the plane containing the first swing direction M is perpendicular to the length direction of the bed board 20. The plane containing the first swing direction M can be a vertical plane, and any direction in the vertical plane is perpendicular to the length direction of the bed board 20. That is, the bed board 20 can tilt and swing left and right along the width direction of the bed board 20 so that the left and right angles of the bed board 20 can be adjusted. This allows the patient lying on the catheterization bed 1 to better adapt to the surgical requirements during the operation, improving the accuracy and safety of the surgical procedure.

[0060] Furthermore, such as Figures 1-2 As shown, the first transmission component 30 and the first driving component 40 are both disposed between the base 10 and the bed plate 20, thereby ensuring the compactness of the overall structure and improving the space utilization of the catheter bed 1.

[0061] For example, there is an installation cavity between the base 10 and the bed plate 20. The first transmission component 30 and the first drive component 40 are both located in the installation cavity. This not only reduces the overall volume of the catheter bed 1, making the overall structure more compact, but also reduces the possibility of interference between the first transmission component 30 and the first drive component 40 and other external structures, ensuring that the catheter bed 1 is more stable during operation.

[0062] Please see Figures 3-5 In some embodiments of this application, the first transmission member 31 includes an arc-shaped tooth structure 311 extending along the first swing direction M; the second transmission member 32 includes a transmission gear 321, which meshes with the arc-shaped tooth structure 311; and the first driving member 40 is used to drive the transmission gear 321 to rotate, so as to drive the first driving member 40, the transmission gear 321 and the bed plate 20 to swing along the first swing direction M.

[0063] Specifically, when the first driving member 40 drives the transmission gear 321 to rotate, the transmission gear 321 meshes with the arc-shaped tooth structure 311. Since the arc-shaped tooth structure 311 is fixed to the base 10, the arc-shaped tooth structure 311 applies a reaction force to the transmission gear 321, causing the transmission gear 321 to drive the bed plate 20 to swing along the first swing direction M. At the same time, the arc-shaped tooth structure 311 is arc-shaped as a whole, so as to ensure the smooth swing of the first transmission member 31 in the first swing direction M.

[0064] For example, such as Figures 3-4 As shown, the arc-shaped tooth structure 311 includes a support portion and multiple teeth. The support portion extends along the first swing direction M, and its bottom wall is a downwardly concave arc surface. The multiple teeth are evenly distributed on the arc surface of the support portion along the first swing direction M, ensuring uniform force distribution when the teeth mesh with the transmission gear 321. The support portion not only provides support for the transmission gear 321, preventing it from shifting during high-speed operation and ensuring the stability of the transmission process, but also provides stable support for the teeth, effectively dispersing local stress during the transmission process.

[0065] Please see Figures 4-5 In some embodiments of this application, the catheter bed 1 further includes a limiting component 50, which includes a first limiting member 51 and a second limiting member 52. The first limiting member 51 is connected to the lower side of the bed board 20, and the second limiting member 52 is connected to the upper side of the base 10. The first limiting member 51 and the second limiting member 52 slide in cooperation to limit the swing stroke of the bed board 20 along the first swing direction M, ensuring that the bed board 20 is adjusted within a safe range and avoiding surgical risks caused by excessive tilting.

[0066] In some embodiments, the limiting component 50 is provided with a buffer member. When the bed board 20 swings to near its limit position, the buffer member can provide a buffering force to the limiting component 50 to reduce the impact force and ensure smooth swinging. For example, the buffer member is a rubber block or a spring to absorb excess energy during the swinging process of the bed board 20.

[0067] Further, please see Figures 5-6 In some embodiments of this application, the first limiting member 51 includes a limiting protrusion 511, and the limiting protrusion 511 is provided with an arc-shaped limiting groove 512 on the side of the bed board 20 along the length direction. The arc-shaped limiting groove 512 extends along the first swing direction M. The second limiting member 52 includes a support block 521, which is located on the side of the limiting protrusion 511 where the arc-shaped limiting groove 512 is provided. A first sliding block 522 is provided on the side of the support block 521 near the limiting protrusion 511. The first sliding block 522 is located in the arc-shaped limiting groove 512 and slides in cooperation with the arc-shaped limiting groove 512 to limit the swing stroke of the bed board 20 along the first swing direction M.

[0068] Specifically, the limiting protrusion 511 and the support block 521 are arranged along the length of the bed board 20. The limiting protrusion 511 and the side of the support block 521 are in contact. When the bed board 20 swings, the first sliding block 522 on the side of the support block 521 slides in the arc-shaped limiting groove 512 on the side of the limiting protrusion 511, thereby ensuring that the bed board 20 swings smoothly and accurately. The arc-shaped limiting groove 512 can prevent the bed board 20 from swinging excessively. The first sliding block 522 can be a bearing or a roller. Taking the first sliding block 522 as a first bearing as an example, the axis of the first bearing extends horizontally. The inner ring of the first bearing is connected to the support block 521, and the outer ring of the first bearing contacts the arc-shaped limiting groove 512 to reduce the frictional resistance between the first bearing and the arc-shaped limiting groove 512, thereby improving the movement flexibility of the first sliding block 522.

[0069] In some embodiments, such as Figure 2 and Figure 4 As shown, multiple sets of limiting components 50 can be provided. These multiple sets of limiting components 50 are spaced apart along the length of the bed board 20. Each set of limiting components 50 works in concert to further enhance the stability and safety of the bed board 20. Taking two sets of limiting components 50 as an example, the two limiting protrusions 511 are located between the two support blocks 521. Since the limiting protrusions 511 and the support blocks 521 are arranged along the length of the bed board 20, the outer sides of the two limiting protrusions 511 contact the inner sides of the two support blocks 521 respectively. This allows the two sets of limiting components 50 to limit the bed board 20 along its length. The outer sides of the two limiting protrusions 511 refer to the sides of the two limiting protrusions 511 that are opposite to each other, and the inner sides of the two support blocks 521 refer to the sides of the two support blocks 521 that are close to each other.

[0070] Furthermore, please see Figures 5-6 In some embodiments of this application, the limiting protrusion 511 is further provided with a first track 513 on the side along the length direction of the bed board 20. The first track 513 extends along the first swing direction M and is spaced apart from the arc-shaped limiting groove 512. The second limiting member 52 also includes a second sliding block 523, which is disposed on the top of the support block 521 and slides with the first track 513.

[0071] Specifically, the first track 513 is located above the arc-shaped limiting groove 512, the first sliding block 522 slides within the arc-shaped limiting groove 512, and the second sliding block 523 slides within the first track 513. The first track 513 and the arc-shaped limiting groove 512 cooperate to form a double limiting mechanism, further restricting the swing range of the bed board 20. The second sliding block 523 can also be used to assist the swing of the bed board 20. Similarly, the second sliding block 523 can also be a bearing or a roller. Taking the second sliding block 523 as a second bearing as an example, the axis of the second bearing is perpendicular to the first swing direction M. The inner ring of the second bearing is connected to the top of the support block 521, and the outer ring of the second bearing contacts the first track 513 to reduce the frictional resistance between the second bearing and the first track 513.

[0072] Please see the figure. Figures 3-4 In some embodiments of this application, the base 10 includes a base 11 and a mounting base 12. The mounting base 12 is located above the base 11 and is slidably connected to the base 11 along a first direction L1. A first transmission component 31 is disposed on the mounting base 12. The bed board 20 is movably connected to the mounting base 12. The first direction L1 is parallel to the width direction of the bed board 20. That is, the bed board 20 can be translated left and right in the width direction, and the bed board 20 can also be adjusted to tilt left and right in the width direction by the first transmission component 30.

[0073] Specifically, the base 11 provides stable support for the various structures above it, ensuring that the structures above the base 11 always remain stable. The mounting base 12 can drive the bed board 20 and the first transmission assembly 30 to slide along the first direction L1, so as to realize the position adjustment of the bed board 20 in the first direction L1.

[0074] In some embodiments, the catheter bed 1 further includes a second transmission assembly 60, which can be disposed inside the mounting base 12 to fully utilize the installation space of the base 10. The user can manually or electrically drive the second transmission assembly 60 to smoothly move the mounting base 12 and the bed board 20 along the first direction L1, precisely adjusting the position of the bed board 20 in the first direction L1 to meet different usage requirements. The specific transmission type of the second transmission assembly 60 includes, but is not limited to, chain drive, belt drive, or gear drive.

[0075] For example, such as Figure 7As shown, the second transmission assembly 60 includes a first guide rail 61 and a second guide rail 62. The first guide rail 61 is disposed on the base 11; the second guide rail 62 is disposed on the mounting base 12 and is slidably connected to the first guide rail 61 along the first direction L1. The first guide rail 61 and the second guide rail 62 cooperate with each other to restrict the movement direction of the mounting base 12, prevent the mounting base 12 and the bed board 20 from shifting position during sliding, and ensure that the mounting base 12 and the bed board 20 move smoothly along the first direction L1. At this time, the user can manually push the bed board 20 or the mounting base 12 to make the bed board 20 slide relative to the base 11 along the first direction L1.

[0076] Alternatively, in some other embodiments, such as Figure 7 As shown, the second transmission assembly 60 includes a first rack 63 and a first gear 64. The first rack 63 is disposed on the mounting base 12 and extends along the first direction L1. The first gear 64 is disposed on the base 11 and rotatably connected to the base 11. The first gear 64 meshes with the first rack 63 and is used to drive the first rack 63 and the mounting base 12 to slide along the first direction L1. The second rack cooperates with the second gear to further optimize the transmission efficiency and ensure the accuracy and stability of the bed plate 20 position adjustment.

[0077] Further, please see Figure 7 In some embodiments of this application, the second transmission assembly 60 further includes a second driving member 65, which is disposed on the base 11 and is connected to the first gear 64 to drive the first gear 64 to rotate, thereby driving the first rack 63 and the mounting base 12 to slide along the first direction L1.

[0078] In this embodiment, the type of the second driving component 65 is not specifically limited. For example, the second driving component 65 can be a motor or a hydraulic device, and its power output is transmitted to the first gear 64 through a transmission shaft to ensure that the transmission of the first gear 64 is smooth and efficient. Alternatively, the second driving component 65 can be an operating handle, and the output shaft of the operating handle is directly connected to the input shaft of the first gear 64. The user drives the first gear 64 to rotate by rotating the operating handle, thereby driving the first rack 63 and the bed plate 20 to move along the first direction L1.

[0079] In some embodiments, such as Figure 8As shown, the second driving component 65 is a drive motor, and the second transmission assembly 60 also includes a reducer 68 and a clutch 69. The reducer 68 is connected to the drive motor and is used to reduce the driving speed of the transmission shaft, increase the transmission torque, and ensure the smooth rotation of the transmission shaft. The clutch 69 is connected between the reducer 68 and the first gear 64 and is used to disconnect or engage the transmission between the transmission shaft and the first gear 64 when needed, facilitating manual adjustment or emergency stop, and further improving the safety and flexibility of operation. When the tubing bed 1 needs to slide along the first direction L1, the user can operate the external control button to engage the clutch 69. After receiving the activation signal from the control button, the drive motor drives the transmission shaft to rotate, causing the reducer 68, clutch 69, and first gear 64 to rotate, thereby driving the first rack 63 and the bed plate 20 to slide along the first direction L1.

[0080] Further, please see Figure 7 and Figure 9 In some embodiments of this application, the second transmission assembly 60 further includes a feedback sensor 66. The feedback sensor 66 is located to the side of the first gear 64 and connected to the base 11. The feedback sensor 66 is used to detect the number of rotations of the first gear 64 and transmits the number of rotations of the first gear 64 to an external display device. The external display device calculates the moving distance of the catheter bed 1 along the first direction L1 and displays the real-time position information of the catheter bed 1. The feedback sensor 66 can monitor the rotation state of the first gear 64 in real time, ensuring accurate detection data. The external display device dynamically updates the moving distance and position of the catheter bed 1 based on the transmitted data, providing users with intuitive operational feedback, making the adjustment process of the catheter bed 1 clear at a glance, and further improving adjustment accuracy and ease of operation.

[0081] It should be noted that the first gear 64 can be used as a transverse gear (e.g., Figure 8 As shown in the diagram, the first gear 64 is used to drive the first rack 63 and the mounting base 12 to slide along the first direction L1, and the first gear 64 can also serve as a feedback gear (as shown in the diagram). Figure 9 As shown in the diagram, the first gear 64 is used to transmit the number of rotations of the first gear 64 to an external display device. Thus, the first gear 64 serves both driving and feedback functions, ensuring efficient system operation. Alternatively, the second transmission component 60 includes both a transverse gear and a feedback gear. The transverse gear drives the rack to slide, while the feedback gear specifically transmits rotational data. The two work together to further improve system stability and operational accuracy, ensuring efficient adjustment of the catheter bed 1 under different usage scenarios.

[0082] Please see Figure 7 In some embodiments of this application, the second transmission assembly 60 further includes a fixing member 67 disposed on the base 11. The fixing member 67 is used to lock and unlock with the mounting base 12 to realize the locking and unlocking of the base 11 and the mounting base 12.

[0083] Specifically, the fixing method of the fastener 67 can be a snap-on fixing, a threaded fixing, or a magnetic fixing. For example, the fastener 67 can be an elastic snap-on, which can engage the base 11 and the mounting base 12 when the mounting base 12 is not moving, thus locking the base 11 and the mounting base 12. Alternatively, the fastener 67 can be a bolt, which can pass through both the base 11 and the mounting base 12 when the mounting base 12 is not moving, and the threaded holes on the base 11 and the mounting base 12 can be threadedly connected to the bolt, thus locking the base 11 and the mounting base 12. Another example is that the fastener 67 can be an electromagnet, which generates magnetism and attracts the mounting base 12 when the mounting base 12 is not moving, thus quickly locking the base 11 and the mounting base 12. This embodiment prevents accidental movement of the catheter bed 1 by locking the base 11 and the mounting base 12, improving the reliability of the mounting base 12 and further enhancing safety. When the catheter bed 1 needs to slide along the first direction L1, the magnetism of the electromagnet can be deactivated by the control button, thereby unlocking the mounting base 12.

[0084] In summary, the method of adjusting the catheter bed 1 to slide along the first direction L1 has two modes: manual adjustment and electric adjustment. Manual adjustment is convenient for fine-tuning, while electric adjustment is efficient and convenient. The combination of the two can meet different operational needs and ensure the flexibility and stability of the adjustment process.

[0085] Secondly, embodiments of this application also provide an angiography X-ray machine (not shown in the figure), including a scanning device, a display device, and a catheter bed 1 as described in any of the above embodiments; the scanning device has a receiving space, and the catheter bed 1 is located in the receiving space; the display device is electrically connected to the scanning device to receive the scanning results of the scanning device.

[0086] Specifically, the scanning device scans the human body with a high-precision instrument and transmits the scanned data to the display device, which displays the collected image data in real time, facilitating accurate diagnosis and treatment of patients by doctors. The design of the catheterization bed 1 can reduce the interference of the component structure on the bed board 20 on the swing of the bed board 20, thereby improving the adjustment performance of the catheterization bed 1 in terms of position and direction.
