[0048] Operating table 7 is fixedly connected to one side end of the slider 6.

[0049] Anesthesia box 14 is fixedly connected to one side end of the outer shell 2.

[0050] A wireless charging component is arranged at the lower end of the operating table 7 to achieve wireless charging of small medical devices.

[0051] In a specific embodiment of the present invention, the base 1, as the basic support part of the entire device, bears all components and additional loads. The outer shell 2 is used to protect the internal components and prevent external environmental factors from affecting the internal electrical components. The motor 3 provides power for the rotation of the threaded rod 4. The threaded rod 4 has a sliding nut inside the slider 6, and by rotating the threaded rod 4, the position of the slider 6 is adjusted, thereby changing the height of the operating table 7. There are two limiting rods 5, which are vertically fixed on the base 1 to ensure that the slider 6 moves in a straight line without deviation. The slider 6 cooperates with both the threaded rod 4 and the limiting rod 5 and can slide smoothly between them. It is responsible for transmitting the power from the motor 3 to the operating table 7, enabling the latter to move up and down. The operating table 7 is a place to place and operate various small medical instruments. The wireless charging component is located below the operating table 7 and is used to support non-contact charging of small medical devices, reducing the trouble caused by traditional plugging and unplugging of the power supply and also reducing the risk of damage caused by frequent plugging and unplugging.

[0052] Specifically, please refer to Figures 1 - 8 The wireless charging component includes a connecting rod 8, a placing table 9, a first limiting block 10, a magnet 11, a wireless charging coil 12, and an induction lamp 13. There are multiple connecting rods 8, first limiting blocks 10, magnets 11, wireless charging coils 12, and induction lamps 13. The connecting rod 8 is fixedly connected to the lower end of the operating table 7. The placing table 9 is slidably connected to the surface of the connecting rod 8. The first limiting block 10 is fixedly connected to the lower end of the connecting rod 8. The magnet 11 is fixedly connected to the upper end of the placing table 9. The wireless charging coil 12 is fixedly connected to the upper end of the placing table 9. The induction lamp 13 is fixedly connected to the upper end of the placing table 9.

By cooperating with the magnet 11, the placement table 9 can be slid along the surface of the connecting rod 8 to fit the lower end of the operation table 7, and the operation table 7 can be stored, creating a larger operation space for medical staff and facilitating their operation. The wireless charging coil 12 is covered with an insulating material and is connected to the computer part through a circuit to jointly draw out the power supply. The 220V single-phase alternating current connected to the computer part is converted into direct current by a rectifier filter circuit, and then this direct current is converted into high-frequency alternating current by an inverter circuit to provide electrical energy for the wireless charging coil 12 on the panel. The induction lamp 13 will automatically light up when it detects that an object is approaching, indicating to the user that this area is ready to receive the device for charging. In addition, the change in the light color can also be used to indicate the charging status, green indicating charging and red indicating misalignment or malfunction. The anesthesia box 14 is used to store anesthetic drugs and other necessities. The switch component is located on one side of the slider 6 to achieve the operation of non-contact opening and closing of the anesthesia box 14, reducing the risk of cross-infection.

[0057] In this embodiment: The rotating rod 16, as the central axis of the adjustment mechanism, allows the rotating block 17 to rotate around it, thereby changing the angle of the display screen 22. The rotating block 17 can rotate freely within a certain range while maintaining good cooperation with the rotating rod 16 to ensure stability during the adjustment process. The second limiting block 18 prevents the rotating block 17 from slipping off the rotating rod 16 and also plays a positioning role. The fixed rods 19, as the rotating structures of the connecting seat 20, ensure that the latter can firmly carry the display screen 22 for rotation. The connecting seat 20 provides a platform on which the display screen 22 can be firmly installed by bolts. The electric push rod 21 is connected to the connecting seat 20 and is used to drive the display screen 22 to adjust the up and down angle to adapt to different viewing angles and personal preferences. The display screen 22 is the main window for medical staff to view the patient's vital sign data and other important information. Through the adjustment mechanism, medical staff can conveniently view the information on the screen at any angle, such as the patient's vital sign data or other important parameters, further optimizing the work process.

[0058] For details, please refer to Figures 1 - 8 , The front end of the base 1 is trapezoidal, and the edges of the base 1 are designed with rounded corners.

[0059] In this embodiment: The front end of the base 1 is designed in a trapezoidal shape, which helps to reduce the obstacles that the trolley may encounter when moving in a narrow space, improving the flexibility and usability of the trolley. At the same time, the edges of the base 1 are designed with rounded corners, avoiding the risk of collision injury or snagging clothes caused by sharp corners, enhancing the use safety and user experience.

[0060] For details, please refer to Figures 1 - 8 , The lower inner wall of the operating table 7 is provided with a T-shaped groove 36. A T-shaped block 23 is slidably connected in the T-shaped groove 36. The upper end of the T-shaped block 23 is fixedly connected to the keyboard tray 24.

[0061] In this embodiment: There are two T-shaped grooves 36 and T-shaped blocks 23. The sliding of the T-shaped block 23 in the T-shaped groove 36 provides a sliding space for the keyboard tray 24, enabling the keyboard to be freely adjusted according to the user's needs. This not only does not affect the operation on the surface of the operating table 7 but also provides a comfortable typing angle. The keyboard tray 24 is used to place the keyboard and provides a comfortable and stable typing platform for the user.

[0062] For details, please refer to Figures 1 - 8 , the lower end of the base 1 is fixedly connected with a moving wheel 25, and one side end of the outer shell 2 is fixedly connected with a handle 26.

[0063] In this embodiment: There are four moving wheels 25, enabling the trolley to move easily in environments such as hospital corridors and operating rooms. For the handle 26, personnel can move the trolley by pushing the handle 26, facilitating the pushing or pulling of the trolley.

[0064] For details, please refer to Figures 1 - 8 , one side end of the base 1 is fixedly connected with a connecting block 27. The connecting block 27 is internally threaded with a screw rod 28, and the lower end of the screw rod 28 is fixedly connected with a gasket 29.

[0065] In this embodiment: There are four connecting blocks 27, screw rods 28, and gaskets 29. To enhance the stability of the base 1, the connecting block 27 is internally provided with a threaded hole for threadedly connecting the screw rod 28. The lower end of the screw rod 28 is fixedly connected with a gasket 29. When it is necessary to adjust the height of the trolley or increase the bottom support area, the position of the gasket 29 can be adjusted by rotating the screw rod 28. This can not only provide additional support force to prevent the trolley from tilting on uneven ground but also protect the floor from damage. In addition, in an emergency, if the moving wheel 25 fails, the gasket 29 can also serve as a temporary support point to ensure the safety and stability of the trolley.

[0066] For details, please refer to Figures 1 - 8 , one side end of the base 1 is fixedly connected with a collision prevention frame 30. The upper end of the collision prevention frame 30 is fixedly connected with a rotating shaft 31, and the circumferential surface of the rotating shaft 31 is rotatably connected with a collision prevention wheel 32.

[0067] In this embodiment: There are two rotating shafts 31 and collision prevention wheels 32. To improve the safety of the trolley in a narrow space, one side end of the base 1 is fixedly connected with a collision prevention frame 30. The upper end of the collision prevention frame 30 is fixedly connected with a rotating shaft 31, and the circumferential surface of the rotating shaft 31 is rotatably connected with a collision prevention wheel 32. The collision prevention wheel 32 can freely rotate when the trolley comes into contact with a wall or other objects during movement, playing a buffering role to reduce the impact force and avoid damage to the trolley or surrounding facilities.

[0068] For details, please refer to Figures 1 - 8 , the surface of the handle 26 is sleeved with an anti-slip sleeve 33, and the surface of the anti-slip sleeve 33 is provided with anti-slip lines.

[0069] In this embodiment: The anti-slip sleeve 33 is used to prevent slipping when a person pushes the handle 26. The surface of the anti-slip sleeve 33 is provided with anti-slip lines, which further enhances the stability of grasping. Even in a humid environment, the safety of grasping can be ensured, facilitating the user to push or pull the trolley.

[0070] The working principle and usage process of the present invention: Through this device, medical staff hold the handle 26 with the anti-slip sleeve 33 and easily move the trolley to the required position through the moving wheels 25. When an impact occurs during the movement, the anti-collision wheel 32 will rotate freely to play a buffering role and reduce the impact force. After reaching the destination, rotate the screw rod 28 to adjust the position of the gasket 29 to fix the trolley. Subsequently, when the medical staff performs an anesthesia operation, turn on the motor 3 to control the slider 6 to move upward, and the box cover 15 can be automatically opened to achieve a touchless operation, reducing the risk of cross-infection. After injecting the anesthetic into the patient, the medical staff can manually rotate the rotating block 17 to adjust the angle of the display screen 22, and the electric push rod 21 is responsible for driving the display screen 22 to move up and down to achieve the height adjustment of the display screen 22, enabling the medical staff to view the key information of the patient at the most comfortable position, improving the work efficiency and operation experience. Subsequently, by controlling the forward and reverse rotation of the motor 3, the threaded rod 4 can be rotated, thereby driving the slider 6 to move up and down along the limiting rod 5 to adjust the operating table 7 to a comfortable height. When the small medical device runs out of power, pull out the placement table 9 downward through the connecting rod 8, and the first limiting block 10 prevents the placement table 9 from slipping. Then place the small medical device at the wireless charging coil 12 for charging, thus solving the problem that the existing hand-numbing trolleys in the prior art often have a single function, only providing a basic moving platform and storage space, and cannot meet the increasingly complex clinical needs.

[0071] Finally, it should be noted that: The above are only the preferred embodiments of the present invention and are not used to limit the present invention.
