[0005] A support mechanism configured to support the operating table;

[0006] A lifting mechanism includes a first driving member, a lifting bracket, and a traveling wheel assembly. The first driving member is connected to the support mechanism and is driven to the lifting bracket. The traveling wheel assembly is connected to the lifting bracket. The first driving member is configured to drive the lifting bracket and the traveling wheel assembly to move relative to the support mechanism in the height direction.

[0007] The driving mechanism includes a second driving member, a driving bracket, and a driving wheel. The second driving member is connected to the lifting bracket via the driving bracket. The second driving member is drivenly connected to the driving wheel, and the second driving member and the driving wheel are configured to move relative to the support mechanism along the height direction with the lifting bracket.

[0008] In one embodiment, the drive bracket is elastically connected to the lifting bracket, so that the drive bracket can drive the second drive member and the drive wheel to move relative to the lifting bracket along the height direction.

[0009] In one embodiment, the support mechanism includes a drive guide extending along the height direction, and the drive bracket is slidably sleeved on the drive guide.

[0010] The drive mechanism further includes an elastic element, which is connected to the lifting bracket and the drive bracket respectively. The elastic element is configured to apply force to the drive bracket so that the drive bracket moves relative to the lifting bracket.

[0011] In one embodiment, the drive wheel is rotatably connected to the drive bracket, and the drive mechanism further includes a transmission assembly disposed between the second drive member and the drive wheel, the transmission assembly comprising:

[0012] A drive gear, which is connected to the output end of the second drive element;

[0013] An intermediate gear component is connected to the drive bracket and meshes with the drive gear;

[0014] A gear ring is connected to the drive wheel, and the gear ring is arranged around the outer periphery of the intermediate gear and the drive gear, and meshes with the intermediate gear.

[0015] In one embodiment, the intermediate gear includes:

[0016] A rotating shaft connected to the drive bracket;

[0017] A transmission gear is rotatably mounted on the rotating shaft, and the transmission gear meshes with the driving gear and the gear ring respectively.

[0018] In one embodiment, the drive mechanism further includes a drive cover, which is connected to the drive bracket via the rotating shaft, and the drive cover and the drive bracket form a receiving cavity, wherein the second drive member and the transmission assembly are disposed within the receiving cavity.

[0019] In one embodiment, the drive mechanism further includes a limiting bearing, which is sleeved on the rotating shaft and disposed between the transmission gear and the drive cover.

[0020] In one embodiment, the drive device further includes a transmission mechanism, the transmission mechanism comprising:

When the operating table needs to be moved, a first drive component drives the lifting bracket to descend, causing the traveling wheel assembly to contact the ground and support the operating table. Simultaneously, the drive mechanism descends with the lifting bracket, causing the drive wheels to also contact the ground. At this time, a second drive component drives the drive wheels to rotate, providing driving force for the movement of the operating table and facilitating easy movement of the operating table by operators in operating rooms and other similar settings. When the operating table does not need to be moved, the first drive component drives the lifting bracket to rise, causing the traveling wheel assembly to rise, thereby allowing the support mechanism to directly contact the ground and stably support the operating table, effectively preventing unexpected movement of the operating table and ensuring the stability and precision of the surgical procedure. Therefore, the drive device in this embodiment can drive the traveling wheel assembly and drive wheels to rise and fall in the height direction through the lifting mechanism, and simultaneously drive the drive wheels to rotate on the ground through the drive mechanism, providing driving force for the operator and improving the ease of moving the operating table.

[0051] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0052] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0053] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0054] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0055] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0056] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0057] In related technologies, operating tables are equipped with casters at the bottom, which are rotatable and grounded. Since the casters are always in contact with the ground, when the operating table does not need to be moved, it is prone to unexpected movement due to external force or slight unevenness in the ground. This not only interferes with the operation of medical staff but also directly affects the precision of the surgery, posing a potential threat to the patient's safety. Furthermore, moving the operating table requires manual pushing, which is inconvenient and increases the burden on medical staff. Therefore, this application provides a drive device and operating table system for an operating table. See also... Figures 1 to 11 As shown, the operating table system 1 includes a drive device 10 for the operating table. The drive device 10 for the operating table can automatically lift and lower the entire operating table through the lifting mechanism 200. At the same time, in the operating room and other scenarios where the operating table needs to be moved, the drive mechanism 300 can provide a certain driving force to the operator to facilitate the movement of the operating table.

[0058] See Figures 3 to 11 As shown, the drive device 10 for an operating table according to an embodiment of this application includes a support mechanism 100, a lifting mechanism 200, and a drive mechanism 300. It should be noted that the height direction in this document refers to the direction of gravity when the drive device 10 is placed on the ground, that is, the direction perpendicular to the ground, and this height direction is represented by the Z-direction.

[0059] The support mechanism 100 serves as the mounting base for the entire drive unit 10. It can be used to support the operating table and to install the lifting mechanism 200 and the drive mechanism 300, so that the operating table can be lifted and driven by the lifting mechanism 200 and the drive mechanism 300.

[0060] The lifting mechanism 200 includes a first drive member 210, a lifting bracket 220, and a wheel assembly 230. The first drive member 210 is connected to the support mechanism 100. For example, the first drive member 210 can be a power component such as a motor or cylinder, used to provide stable lifting power to the lifting bracket 220 and the wheel assembly 230. The wheel assembly 230 is connected to the lifting bracket 220. For example, the wheel assembly 230 can include casters and wheel frames. The casters are connected to the lifting bracket 220 via the wheel frames. When supporting the operating table, the drive device 10 contacts the ground through the casters. Optionally, the lifting bracket 220 can be connected to two wheel assemblies 230 to stably support the operating table. The first drive member 210 is driven by the lifting bracket 220 and is configured to drive the lifting bracket 220 and the wheel assembly 230 connected to the lifting bracket 220 to move relative to the support mechanism 100 in the height direction. Since the walking wheel assembly 230 connected to the lifting bracket 220 is in contact with the ground, when the walking wheel assembly 230 descends relative to the support mechanism 100 in the height direction, the operating table mounted on the support mechanism 100 will rise. At this time, the operating table is supported by the walking wheel assembly 230, thereby allowing the operating table to move. When the walking wheel assembly 230 rises relative to the support mechanism 100 in the height direction, the operating table mounted on the support mechanism 100 will descend until the bottom surface of the walking wheel assembly 230 is higher than the bottom surface of the support mechanism 100. At this time, the operating table is supported by the support mechanism 100 to prevent the operating table from moving unexpectedly.

[0061] The drive mechanism 300 includes a second drive member 310, a drive bracket 320, and a drive wheel 330. The second drive member 310 is connected to the lifting bracket 220 via the drive bracket 320. When the lifting bracket 220 moves along the height direction under the action of the first drive member 210, the second drive member 310 and the drive bracket 320 will move along the height direction relative to the support mechanism 100 along with the lifting bracket 220. Furthermore, the second drive member 310 is drivenly connected to the drive wheel 330, enabling the drive wheel 330 to move along the height direction with the first drive member 210. This allows for simultaneous adjustment of the position of the drive wheel 330 and the walking wheel assembly 230 in the height direction, ensuring that the drive wheel 330 and the walking wheel assembly 230 can simultaneously contact the ground. At this time, the first drive member 210 can provide power to the drive wheel 330, causing the drive wheel 330 to rotate relative to the ground, thereby driving the transfer of the operating table.

[0062] According to the driving device 10 of this application embodiment, when the operating table needs to be moved, the first driving member 210 drives the lifting bracket 220 to descend, thereby causing the walking wheel assembly 230 to contact the ground and support the operating table. Simultaneously, the driving mechanism 300 descends with the lifting bracket 220, causing the driving wheel 330 to also contact the ground. At this time, the second driving member 310 can drive the driving wheel 330 to rotate, thus providing driving force for the movement of the operating table, facilitating easy movement of the operating table by operators in operating rooms and other similar settings. When the operating table does not need to be moved, the first driving member 210 drives the lifting bracket 220 to rise, thereby causing the walking wheel assembly 230 to rise, thus allowing the support mechanism 100 to directly contact the ground and stably support the operating table, effectively avoiding unexpected movement of the operating table, thus ensuring the stability of the surgical procedure and the precision of the surgery. Therefore, the drive device 10 of this application embodiment can drive the walking wheel assembly 230 and the drive wheel 330 to rise and fall along the height direction through the lifting mechanism 200, and at the same time, the drive mechanism 300 can drive the drive wheel 330 to rotate on the ground, thereby providing driving force for the operator and improving the convenience of moving the operating table.

[0063] See Figures 4 to 7 As shown, in some embodiments, the drive bracket 320 and the lifting bracket 220 are elastically connected, enabling the drive bracket 320 to drive the second drive member 310 and the drive wheel 330 to move relative to the lifting bracket 220 in the height direction. The elastic connection means that the drive bracket 320 and the lifting bracket 220 are connected by a component with elastic force, making the distance between them adjustable. During the movement of the operating table by the drive wheel 330, when the operating table moves to an uneven area, the protrusions or depressions in the ground will exert a force on the drive wheel 330 in the height direction. At this time, the drive bracket 320 can move relative to the lifting bracket 220, causing the drive wheel 330 to move closer to or further away from the lifting bracket 220 in the height direction, ensuring that the drive wheel 330 always remains in contact with the ground. Therefore, when the drive bracket 320 is elastically connected to the lifting bracket 220, the drive wheel 330 can adaptively adjust its position along the height direction with the drive bracket 320. This not only avoids the problem of the drive wheel 330 being suspended due to uneven ground, thus preventing loss of driving force and ensuring the continuity and stability of the movement process, but also effectively buffers the impact of uneven ground on the drive mechanism 300 and the lifting mechanism 200, reducing the transmission of vibration to the operating table and avoiding affecting the patient's treatment safety.

[0064] Further, see Figures 3 to 7As shown, in some embodiments, the support mechanism 100 includes a drive guide 140, which extends along the height direction. For example, the support mechanism 100 may include one or more drive guides 140, which may be configured as straight rods extending along the height direction, and the multiple drive guides 140 are parallel to each other. A drive bracket 320 is slidably fitted onto the drive guide 140. For example, the drive bracket 320 may be provided with a drive guide hole adapted to the drive guide 140, allowing the drive bracket 320 to be slidably fitted onto the drive guide 140 through the drive guide hole. The drive guide 140 can guide the movement of the drive bracket 320, ensuring that the drive bracket 320 does not deviate or sway when moving relative to the lifting bracket 220 along the height direction, thereby improving the stability and accuracy of the movement of the drive bracket 320 and the drive wheel 330.

[0065] Furthermore, the drive mechanism 300 also includes an elastic element 340, which is connected to both the lifting bracket 220 and the drive bracket 320. The elastic element 340 is configured to apply force to the drive bracket 320, causing the drive bracket 320 to move relative to the lifting bracket 220. For example, the elastic element 340 can be a component with elastic force, such as a shock-absorbing spring or an elastic sheet. Taking a shock-absorbing spring as an example, the shock-absorbing spring can be sleeved on the outer periphery of the drive guide 140. The drive bracket 320 is located at the bottom of the lifting bracket 220 in the height direction, and the two ends of the shock-absorbing spring are fixedly connected to the lifting bracket 220 and the drive bracket 320, respectively. When the drive device 10 is placed on the ground, the shock-absorbing spring is in a compressed state. At this time, the shock-absorbing spring continuously applies a force to the drive bracket 320 in the height direction away from the lifting bracket 220, causing the drive bracket 320 to drive the drive wheel 330 to remain in contact with the ground. Therefore, the elastic element 340 can adaptively adjust the height of the drive wheel 330 through its own elastic deformation, ensuring that the drive wheel 330 always remains in contact with the ground and guaranteeing stable transmission of driving force. At the same time, the elastic element 340 can buffer the impact force of the ground, reducing the impact of vibrations caused by uneven ground on the stability of the operating table.

[0066] See Figures 4 to 7As shown, in some embodiments, the drive mechanism 300 further includes a transmission assembly 350 disposed between the second drive member 310 and the drive wheel 330. The transmission assembly 350 includes a drive gear 351, an intermediate gear 352, and a gear ring 353 for power transmission. Specifically, the drive gear 351 is connected to the output end of the second drive member 310. For example, when the second drive member 310 selects a motor, the drive gear 351 is connected to the output shaft of the electrode, enabling the second drive member 310 to drive the drive gear 351 to rotate. The intermediate gear 352 is connected to the drive bracket 320 and meshes with the drive gear 351, so that there is a suitable transmission ratio between the drive gear 351 and the gear ring 353. The gear ring 353 is annular and surrounds the outer periphery of the intermediate gear 352 and the drive gear 351. The inner side of the gear ring 353 meshes with the intermediate gear 352, which in turn meshes with the drive gear 351, allowing the drive gear 351 to drive the gear ring 353 to rotate via the intermediate gear 352. The gear ring 353 is connected to the drive wheel 330, which is rotatably connected to the drive bracket 320, for example, via a bearing. When the second drive member 310 drives the drive gear 351 to rotate, the drive gear 351 meshes with and drives the intermediate gear 352 to rotate. The intermediate gear 352 then meshes with and drives the gear ring 353 to rotate, causing the drive wheel 330 to rotate synchronously, thus moving the operating table forward or backward. Therefore, the transmission assembly 350 achieves power transmission through gear meshing, ensuring that the power from the second drive member 310 is efficiently and stably transmitted to the drive wheel 330, improving the stability and controllability of the drive wheel 330's rotation, and ensuring smooth movement of the operating table.

[0067] Further, see Figures 4 to 7 As shown, in some embodiments, the intermediate gear component 352 includes a rotating shaft 3521 and a transmission gear 3522. The rotating shaft 3521 is connected to the drive bracket 320. For example, the rotating shaft 3521 can be fixedly connected to the drive bracket 320 by welding or other means to ensure that the rotating shaft 3521 does not rotate or shift during transmission. The transmission gear 3522 is rotatably sleeved on the rotating shaft 3521. For example, the transmission gear 3522 can be provided with a mounting hole that mates with the rotating shaft 3521, and is sleeved on the outer circumference of the rotating shaft 3521 through the mounting hole. At the same time, a bearing is provided between the transmission gear 3522 and the rotating shaft 3521, so that the transmission gear 3522 can rotate relative to the rotating shaft 3521. Furthermore, the transmission gear 3522 meshes with the driving gear 351 and the gear ring 353 respectively, making the power transmission between the driving gear 351 and the gear ring 353 smoother, which helps to reduce vibration and noise during transmission.

[0068] Optionally, the number of intermediate gear components 352 can be set to multiple, such as two, three, four, etc. The multiple intermediate gear components 352 are evenly distributed around the circumference of the driving gear 351, so that the power transmitted by the driving gear 351 can be evenly transmitted to the gear ring 353 through the multiple intermediate gear components 352, ensuring the stability of power transmission.

[0069] See Figure 4 , Figure 8 , Figure 10 and Figure 11 As shown, in some embodiments, the drive mechanism 300 further includes a drive cover 360, which is connected to the drive bracket 320 via a rotating shaft 3521. A gap exists between the drive cover 360 and the drive bracket 320 to accommodate a gear ring 353, allowing the gear ring 353 to connect with the drive wheel 330. Furthermore, the drive cover 360 and the drive bracket 320 form a receiving cavity 300a, within which the second drive member 310 and the transmission assembly 350 are disposed. This not only protects the second drive member 310 and the transmission assembly 350 but also makes the structure of the drive mechanism 300 more compact, facilitating miniaturization and adapting to the installation space requirements at the bottom of the operating table.

[0070] Further, see Figures 8 to 11As shown, the drive bracket 320 includes a frame 321 and a drive frame 322. The frame 321 has a drive guide hole, allowing it to slidably fit onto the drive guide member 140. The drive frame 322 is connected to the frame 321, and a hollow cavity is provided inside the drive frame 322, which constitutes a portion of the receiving cavity 300a. Specifically, the two ends of the rotating shaft 3521 are connected to the drive frame 322 and the drive cover 360, respectively, so that the drive cover 360 and the drive frame 322 form the receiving cavity 300a. The second drive member 310 is disposed within the receiving cavity 300a, specifically within the hollow cavity inside the drive frame 322. The transmission assembly 350 is disposed on the side of the second drive member 310 near the drive cover 360. The drive wheel 330 is rotatably fitted onto the outside of the drive frame 322 via a bearing. The drive wheel 330 is coaxial with the output end of the second drive member 310, so as to connect and cooperate with the gear ring 353 for transmission. Therefore, the drive cover 360 can prevent dust, water stains, and other impurities in the operating room environment from contaminating the transmission component 350 and the second drive member 310, thereby protecting the second drive member 310 and the transmission component 350 and extending the service life of the drive mechanism 300. Simultaneously, placing the second drive member 310 and the transmission component 350 within the receiving cavity 300a can effectively reduce noise generated during transmission, lowering noise pollution in the operating environment. Furthermore, the drive cover 360 and the drive bracket 320 are connected via a pivot 3521, creating a gap between them. This ensures the overall structural strength of the drive mechanism 300 and provides space for the installation of the transmission component 350, facilitating effective transmission between the transmission component 350 and the drive wheel 330 and ensuring the stability of power transmission.

[0071] Further, see Figure 9 and Figure 11 As shown, in some embodiments, the drive mechanism 300 further includes a limiting bearing 370. The limiting bearing 370 is sleeved on the rotating shaft 3521 and is positioned between the transmission gear 3522 and the drive cover 360. Thus, the limiting bearing 370 can provide axial support for the transmission gear 3522 along the rotating shaft 3521, preventing axial movement of the transmission gear 3522 during rotation from affecting the meshing accuracy with the drive gear 351 and the gear ring 353. Furthermore, when the transmission gear 3522 rotates with the drive gear 351, the transmission gear 3522 can rotate relative to the drive cover 360 via the limiting bearing 370, reducing the friction generated during the rotation of the transmission gear 3522 and effectively improving transmission efficiency.

[0072] See Figures 4 to 7 As shown, in some embodiments, the drive device 10 for the operating table further includes a transmission mechanism 400, which transmits power to the lifting bracket 220, causing the lifting bracket 220 to move up and down in the height direction.

[0073] Specifically, the transmission mechanism 400 includes a lifting screw 410, a screw nut 420, and an adjusting member 430. The lifting screw 410 is rotatably connected to the support mechanism 100 and extends along the height direction. For example, the lifting screw 410 can be a ball screw, and both ends of the lifting screw 410 are rotatably connected to the support mechanism 100 via bearings or other rotating support structures, ensuring that the lifting screw 410 can rotate around its own axis. The lifting screw 410 is connected to the output end of the first driving member 210, thereby enabling the first driving member 210 to drive the lifting screw 410 to rotate relative to the support mechanism 100. For example, the output end of the first driving member 210 can be connected to the lifting screw 410 via a first gear 441 and a second gear 442. The first gear 441 is coaxially arranged with the output end of the first driving member 210, and the second gear 442 is sleeved on the outside of the lifting screw 410, with the first gear 441 and the second gear 442 meshing and transmitting power. A lead screw nut 420 is sleeved on the lifting lead screw 410. The lead screw nut 420 cooperates with the lifting lead screw 410 so that when the lifting lead screw 410 rotates, the lead screw nut 420 can move linearly along the axial direction (i.e., the height direction) of the lifting lead screw 410. Furthermore, the lead screw nut 420 is connected to the lifting bracket 220, so that the lifting bracket 220 can move synchronously with the lead screw nut 420 along the height direction. An adjusting member 430 is connected to the lifting lead screw 410, and the adjusting member 430 protrudes from the support mechanism 100 in the height direction. For example, the adjusting member 430 is connected to the top end of the lifting lead screw 410 and protrudes from the top surface of the support mechanism 100 in the height direction. In this embodiment, the adjusting member 430 can be configured as a nut-like structure so that the lifting lead screw 410 can be rotated by turning the adjusting member 430 with a wrench or other tools.

[0074] Therefore, since the output end of the first driving component 210 forms a transmission connection with the lifting screw 410, the first driving component 210 can automatically drive the lifting screw 410, making the drive efficient and convenient. Simultaneously, in the event of a power failure in the first driving component 210, the operator can manually rotate the adjusting component 430 to drive the lifting screw 410 to adjust the height of the lifting support 220, thereby raising the operating table.

[0075] It is understood that there can be multiple lifting screws 410, and correspondingly multiple screw nuts 420 and adjusting components 430. Multiple lifting screws 410 can share a single first driving component 210, or they can be driven by different first driving components 210. For example, when multiple lifting screws 410 share a single first driving component 210, the output end of the first driving component 210 is connected to a first gear 441, and each lifting screw 410 is fitted with a second gear 442. The first gear 441 meshes with all the second gears 442, thus allowing multiple lifting screws 410 to rotate simultaneously through a single first driving component 210, thereby driving the lifting bracket 220 to move smoothly.

[0076] See Figures 3 to 7 As shown, in some embodiments, the support mechanism 100 includes a support top seat 110, a support base 120, and a lifting guide 130. The support base 120 and the support top seat 110 are spaced apart along the height direction, i.e., there is a gap between them. The support top seat 110 is configured to mount an operating table, and the support base 120 is located at the bottom of the support top seat 110 for placement on the ground. The lifting guide 130 connects the support base 120 and the support top seat 110. The lifting guide 130 can be configured as a straight rod extending along the height direction, and multiple lift guides can be provided, such as four, five, or six, evenly distributed between the support top seat 110 and the support base 120. A lifting bracket 220 is disposed along the height direction between the support base 120 and the support top seat 110, and the lifting bracket 220 is slidably fitted onto the lifting guide 130. Optionally, a bushing 150 can be provided between the lifting bracket 220 and the lifting guide 130 to reduce sliding friction. The lifting guide 130 can provide guiding constraints for the lifting movement of the lifting bracket 220, ensuring that the lifting bracket 220 does not deviate, tilt or sway when moving in the height direction, thereby ensuring the stability of the lifting movement of the traveling wheel assembly 230 and the drive wheel 330.

[0077] Furthermore, the drive mechanism 300 is positioned between the lifting bracket 220 and the support base 120. Specifically, the support base 120 has an opening to ensure that the drive wheel 330 of the drive mechanism 300 remains in contact with the ground, allowing the drive wheel 330 to rotate relative to the ground to drive the operating table's movement. Thus, when the operating table needs to be moved, the first drive member 210 drives the lifting bracket 220 and the wheel assembly 230 to descend, causing the wheel assembly 230 to contact the ground and support the operating table. At this time, the support base 120 rises relative to the ground, relying on the wheel assembly 230 for support. Simultaneously, the drive wheel 330 contacts the ground, providing driving force for the movement of the operating table, facilitating its movement. When the operating table does not need to be moved, the first drive member 210 drives the lifting bracket 220 and the wheel assembly 230 to rise, causing the support base 120 to directly contact the ground. In this case, the support mechanism 100 supports the operating table, effectively preventing unexpected movement of the operating table, thus ensuring the stability of the surgical procedure and the precision of the surgery.

[0078] In addition, see Figure 5 and Figure 7 As shown, the drive unit 10 also includes a wiring conduit assembly 500, which is disposed between the lifting bracket 220 and the support base 120. For example, the wiring conduit assembly 500 may include a protective tube and a wiring harness for electrical connection with the first drive member 210 and the second drive member 310 to realize power supply and control functions.

[0079] See Figures 1 to 2 As shown, another embodiment of this application provides an operating table system 1, which includes a drive device 10 for the operating table as described in any of the above embodiments. Exemplarily, the operating table system 1 includes a drive device 10, a driven device 20, and an operating table base 30. The driven device 20 differs from the drive device 10 in that it does not have a drive mechanism 300; instead, it includes a support mechanism 100 and a lifting mechanism 200 of the drive device 10, thus enabling automatic or manual lifting of the operating table. The two ends of the operating table base 30 are fixed to the driven device 20 and the drive device 10, respectively, and the top of the operating table base 30 is used to mount the operating table. Therefore, when transferring the operating table, both the drive device 10 and the driven device 20 can lift it, and the drive mechanism 300 of the drive device 10 can assist in moving the operating table, making the transfer of the operating table more convenient. Furthermore, by manually pushing the operating table base 30 close to the driven device 20, the orientation of the operating table can be adjusted, enabling multi-directional movement of the operating table.

[0080] It is understood that in other alternative embodiments, the operating table system 1 may consist of only two drive units 10 and an operating table base 30, with both ends of the operating table base 30 fixed to two different drive units 10. In this case, using two drive units 10 to assist in transferring the operating table can further reduce the difficulty of transfer and improve the efficiency of transfer.

[0081] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0082] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
