[0002] The lifting instrument tray and the injection table are commonly used medical auxiliary equipment in surgical operations. They can be used to place various medical instruments and drugs required for surgeries. In order to improve the convenience of use, various types of lifting rods are adopted at the bottom of many lifting instrument trays, and a lifting control lever is configured. Currently, the commonly used lifting control lever can be configured as a foot-operated type, which can effectively avoid the contact of the hands of surgical staff, avoid contamination and improve convenience. However, in the traditional technology, using a foot-operated control lever for lifting operations will result in a decrease in the accuracy of the lifting operation and is prone to shaking, which will affect the medical instruments and drugs placed above. After retrieval, the Chinese patent with the application number CN201520937550.6 discloses a liftable foot-operated instrument tray, including a tray, a chassis is arranged below the tray, and a lifting device is arranged on the chassis. This solution uses a hydraulic device to adjust the height of the tray and uses a foot pedal to drive the hydraulic device. The foot pedal is arranged on one side of the device, and it is easy to cause the device to shake to one side when stepping on it. Moreover, the up-and-down stepping motion is used for lifting control, and the rising of the lifting device is not smooth and stable. Therefore, in the technical field of medical equipment, it is necessary to propose a foot-operated lifting instrument tray and an injection table that can improve the lifting stability of the instrument tray and the injection table.

[0030] Embodiment 1

[0031] Refer to the attached Figure 1-3, this application provides a foot-operated lifting instrument tray and injection table, including a lifting mechanism 1, an instrument tray 2, an injection table 3, and a base 4. The injection table 3 is arranged at the upper end of the lifting mechanism 1, the instrument tray 2 is arranged at the upper end of the injection table 3. The lifting mechanism 1 includes a lifting rod 101, a foot pedal 102, a Z-shaped rod 103, and a connecting mechanism 5. There are two lifting rods 101, which are symmetrically arranged on both sides of the lower end of the injection table 3. The foot pedal 102 is arranged between the two lifting rods 101. The Z-shaped rod 103 and the connecting mechanism 5 are symmetrically arranged on both sides of the foot pedal 102. One side of the foot pedal 102 is rotatably connected to one side of the Z-shaped rod 103. One side of the Z-shaped rod 103 is connected to the connecting mechanism 5, and the connecting mechanism 5 is connected to the lifting rod 101. The foot pedal 102 can drive the Z-shaped rod 103 to rotate, and control the lifting of the lifting rod 101 through the Z-shaped rod 103 and the connecting mechanism 5. By setting the foot pedal 102, the Z-shaped rod 103, and the connecting mechanism 5, this device can control the lifting of the lifting rod 101 by stepping on the foot pedal 102, controlling the foot pedal 102 to perform a circular motion, and driving the lifting mechanism 1 to perform a lifting motion through the Z-shaped rod 103 and the connecting mechanism 5. When the operator steps on the foot pedal 102 to rotate forward, the lifting rod 101 rises. When the operator steps on the foot pedal 102 to rotate backward, the lifting rod 101 descends, which can conveniently and smoothly control the lifting motion of the lifting rod 101. At the same time, the foot pedal 102 is arranged in the middle of the two lifting rods 101, which can prevent the instrument tray 2 and the injection table 3 from tilting to one side and shaking, improving stability. In summary, by setting the foot pedal 102, the Z-shaped rod 103, and the connecting mechanism 5, this device can conveniently control the lifting of the lifting rod 101 and effectively improve the stability of the lifting of the instrument tray 2 and the injection table 3.

[0032] Specifically, the connecting mechanism 5 includes a connecting sleeve 501 and a connecting worm 502. The lifting rod 101 includes a lifting housing 104, a threaded sleeve 105, a threaded rod 106, and a lifting worm gear 107. One side of the Z-shaped rod 103 is fixedly connected to the connecting worm 502. The other side of the connecting worm 502 is engaged and connected to the lifting worm gear 107. The upper end of the lifting worm gear 107 is fixedly connected to the threaded rod 106. The threaded rod 106 is threadedly connected to the threaded sleeve 105. The upper end of the threaded sleeve 105 is fixedly connected to the lower end of the injection table 3. By setting the connecting worm 502 and the lifting worm gear 107 to be engaged and connected, this device can convert the circular motion of the foot pedal 102 into the lifting motion of the threaded rod 106 and the threaded sleeve 105, making the lifting motion of this device more stable.

[0033] Specifically, a limiting rod 108 is provided on one side of the upper end of the foot pedal 102. When a surgical staff steps on the foot pedal 102, the limiting rod 108 enables the surgical staff to place the sole of the foot through the side without the limiting rod 108 and then move the sole of the foot between the limiting rod 108 and the foot pedal 102, and can push the foot pedal 102 to rotate upward labor-savingly through the limiting rod 108, so that when the surgical staff steps on the foot pedal 102 to perform a circular motion, it is more labor-saving and smooth.

[0034] Specifically, anti-slip bumps 109 are provided on the upper end of the foot pedal 102. The anti-slip bumps 109 can prevent the sole of the foot from sliding with the foot pedal 102 when stepping on the foot pedal 102, and improve the reliability of the device.

[0035] Embodiment 2

[0036] Reference appendix Figure 1-6 In this embodiment, the difference from Embodiment 1 is that a universal wheel mechanism 6 is provided at the lower end of the base 4. By providing the universal wheel mechanism 6, the device can be conveniently moved.

[0037] Specifically, the universal wheel mechanism 6 includes a pulley 602, a universal wheel sleeve 601, a rotating ring 603 and a universal wheel connecting rod 604. An annular slot 605 is provided on the inner wall of the universal wheel sleeve 601. The rotating ring 603 is rotatably provided in the annular slot 605. The upper end of the pulley 602 is connected to the rotating ring 603 through the universal wheel connecting rod 604. The upper end of the universal wheel sleeve 601 is fixedly connected to the base 4. By providing the annular slot 605 to cooperate with the rotating ring 603, the universal wheel mechanism 6 can rotate and adjust the direction smoothly, making the movement of the device more flexible and reliable.

[0038] Specifically, a locking mechanism 7 is provided inside the universal wheel sleeve 601. The locking mechanism 7 includes a push rod 701, a locking connecting rod 702, a locking connecting disc 703, a fixing plate 704, a fixing straight rod 705, and a fixing ball 706. The upper end of the fixing ball 706 is fixedly connected to the lower end of the fixing straight rod 705. Ring-shaped semi-circular grooves 606 with the same diameter as the fixing ball 706 are provided in the middle of both sides of the pulley 602. There are two fixing straight rods 705, and the two fixing straight rods 705 are symmetrically arranged at the lower end of the locking connecting disc 703. The fixing plate 704 is arranged between the two fixing straight rods 705. The lower end of the fixing plate 704 is made of rubber material. The upper end of the locking connecting disc 703 is hinged to the lower end of the locking connecting rod 702. The upper end of the locking connecting rod 702 is hinged to the middle of the push rod 701. An opening 607 is provided on the side wall of the universal wheel sleeve 601. The push rod 701 passes through the opening 607 and is hinged to the inner wall of the universal wheel sleeve 601. By setting the locking mechanism 7 in this device, the push rod 701 can be used to push the locking connecting rod 702 and the locking connecting disc 703 to move downward, thereby driving the fixing plate 704 and the fixing straight rod 705 to move downward. The fixing balls 706 at the lower ends of the two fixing straight rods 705 are embedded in the ring-shaped semi-circular grooves 606 for clamping, and at the same time, the pulley 602 is locked in cooperation with the fixing plate 704 to prevent the pulley 602 from rotating.

[0039] Specifically, the connecting line of the center points of the two fixing straight rods 705 is parallel to the foot pedal 102. By setting the connecting line of the center points of the fixing straight rods 705 to be parallel to the foot pedal 102 in this device, the orientation direction when the pulley 602 is locked can be controlled, so that the rolling direction when the pulley 602 is locked is parallel to the foot pedal 102. Refer to the appendix Figure 6 , when the orientation of the pulley 602 is not perpendicular to the connecting line of the center points of the fixing straight rods 705, the push rod 701 is pressed down to push the fixing straight rod 705 to move downward, and the fixing ball 706 presses down on the arc edge of the pulley 602, forcing the pulley 602 to rotate to the perpendicular direction of the connecting line of the center points of the fixing straight rods 705 and be locked. When performing the lifting operation, the foot pedal 102 may cause the device to shake, and the force exerted by the foot pedal 102 on this device is mainly in the direction perpendicular to the foot pedal 102. When the pulley 602 is locked, the rolling direction is set to be perpendicular to the applied force, preventing the pulley 602 from rolling due to the force of the foot pedal 102, which can further reduce shaking and movement and improve the reliability of this device.

[0040] The above are only the specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily conceive of changes or substitutions, which should all be covered within the protection scope of the present utility model. The protection scope of the present utility model shall be subject to the protection scope of the said claims.
