Description

Technical Field

[0001] This invention relates to the field of medical and nursing auxiliary equipment technology, specifically to a tray fixing device for operating room nursing. Background Technology

[0002] Operating room tray securing devices are crucial auxiliary equipment in medical care, bearing the important responsibility of supporting surgical instruments, medications, and consumables. Their performance directly affects the smoothness of surgical procedures and medical safety. As surgical procedures become increasingly refined and diverse, the variety of surgical instruments continues to grow, placing higher standards on the adaptability, stability, and operational flexibility of tray securing devices. An ideal tray securing device should ensure the stable fixation of trays of different sizes, preventing instruments from colliding or falling, while also facilitating quick access to instruments by medical staff, reducing operational redundancy, and ensuring the efficient progress of surgical procedures. It thus becomes an important support for improving the quality and efficiency of operating room nursing care.

[0003] A search revealed existing patents for related tray fixing devices, such as the published utility model patents "A Multifunctional Tray Rack for Operating Rooms" (Patent No.: CN222323651U, Application No.: CN202420644896.6) and "A Nursing Tray Support" (Patent No.: CN221636507U, Application No.: CN202420082632.3). The former uses partitions to divide the space inside the tray, but the fixing method relies solely on the physical limitation of the insertion cavity, lacking an elastic clamping structure, making it unsuitable for trays of different widths, and its fixing stability is insufficient. The latter, while capable of placing trays in batches, has adjustment functions limited to adjusting the height of the holes, lacking multi-dimensional adjustment capabilities such as horizontal rotation and angle tilt. Furthermore, most existing devices lack buffer protection structures, easily damaging the tray or instruments during clamping, and the adjustment operation is cumbersome, requiring medical staff to frequently adjust their posture to handle instruments, increasing workload and failing to meet the efficient and precise nursing needs of the operating room. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example: like Figure 1-6As shown, this embodiment of the invention provides a tray fixing device for operating room care, including a base 1. A rotating shaft 12 is rotatably connected to the upper center of the base 1. A support 13 is fixedly connected to the top of the rotating shaft 12. Columns 30 are fixedly connected to both ends of the inner side of the support 13. A bracket 10 is slidably connected to the column 30. A rack 23 is fixedly connected to the front end of the bracket 10. A U-shaped frame 8 is fixedly connected upward through the support 13 to the top of the column 30. A fixing frame 9 is fixedly connected to the top of the support 13 and is installed on the outer side of the bracket 10. A motor 24 is fixedly connected to the inner side of the fixing frame 9. A gear 25 is fixedly connected to the output end of the motor 24. The gear 25 meshes with the rack 23. The rear end of the bracket 10 is slidably connected to... Inside the fixed frame 9, a rotating shaft 31 is rotatably connected to the inner side of the U-shaped frame 8. A rotating frame 5 is fixedly connected to the inner end of the rotating shaft 31, and a support platform 6 is fixedly connected to the top of the rotating frame 5. The support platform 6 has inner grooves 35 at both ends, with two sliding rods 36 fixedly connected inside the grooves 35. A limiting plate 37 is slidably connected to the sliding rods 36, and a clamping plate 21 is fixedly connected to the other end of the limiting plate 37. The clamping plate 21 is L-shaped and extends through the interior of the support platform 6. A tray body 7 is provided at the top of the support platform 6 and the inner end of the clamping plate 21. The base 1 is made of high-strength aluminum alloy to ensure support stability while reducing overall weight. The rotating shaft 12 is connected to the base 1 via a deep groove ball bearing to reduce the coefficient of rotational friction. The support seat 13 has a rectangular frame structure, and the column 30 is welded to the support seat 13 to ensure connection strength. A wear-resistant bushing is provided at the sliding connection between the bracket 10 and the column 30 to extend service life. The fixed frame 9 has a U-shaped cover structure. Motor 24 is fixed to the mounting plate inside the fixed frame 9 by bolts. Gear 25 is connected to the output end of motor 24 by a key. Rack 23 is integrally formed with bracket 10 by welding, resulting in high meshing transmission precision and enabling smooth lifting and lowering of bracket 10. U-shaped frame 8 is formed by bending steel plate. Rotating shaft 31 is also connected to U-shaped frame 8 by bearing. Rotating frame 5 has a triangular support structure and is welded to support platform 6. Support platform 6 is a rectangular flat plate with an anti-slip surface. Inner groove 35 is a rectangular groove. Two sliding rods 36 are parallel and symmetrically distributed. Limiting plate 37 is clearance-fitted with sliding rods 36. The L-shaped structure of clamping plate 21 can simultaneously limit the sides and bottom of pallet body 7, ensuring stable pallet placement.

[0019] A spring 34 is fitted onto the slide bar 36. One end of the spring 34 is fixedly connected to the limiting plate 37, and the other end is fixedly connected to one end of the inner groove 35. The spring 34 is a stainless steel compression spring with an adapted elastic coefficient, providing sufficient clamping force to secure the tray without causing deformation due to excessive elasticity. The spring 34 is welded to the limiting plate 37 and the inner groove 35 to prevent displacement during extension and retraction. When the tray body 7 is placed in or removed, the spring 34 can automatically reset the limiting plate 37 and the clamping plate 21 through its own extension and retraction, enabling quick loading and unloading of the tray. An extension plate 14 is fixedly connected to one end of the outer side of the support platform 6. A clamping plate 22 is fixedly connected to the end of the extension plate 14. The extension plate 14 and the support platform 6 are integrally formed, with its length designed according to common pallet sizes to ensure effective positioning of the clamping plate 22. The clamping plate 22 is a rectangular steel plate perpendicular to the extension plate 14, with rubber cushioning pads adhered to its inner wall. This enhances friction with the pallet and prevents damage from collisions. The clamping plate 22 and the extension plate 14 are fixed by welding, with a perpendicularity error not exceeding 0.5mm, ensuring accurate pallet positioning.

[0020] An extension plate 19 is fixedly connected to the other end of the outer side of the support platform 6. A cylinder 15 is fixedly connected to the lower center of the support platform 6. The extension plate 19 and the extension plate 14 are symmetrically distributed on both sides of the support platform 6. They are also integrally molded structures with the same thickness as the support platform 6 to ensure structural strength. The cylinder 15 is a small mini cylinder, which is fixed to the mounting base under the support platform 6 by bolts. The air inlet and outlet of the cylinder 15 are connected to the external air circuit system through air pipes. Its stroke is designed to be adapted to the width of the pallet to ensure effective clamping of pallets of different sizes.

[0021] The extension plate 2 19 has a through groove 16, and a sliding rod 17 is fixedly connected inside the groove 16. The groove 16 is a rectangular through groove, and its opening direction is consistent with the length direction of the extension plate 2 19. The groove width is slightly larger than the thickness of the clamping plate 18 to ensure smooth sliding of the clamping plate 18. The sliding rod 17 is a cylindrical optical shaft, and its two ends are fixed to the side wall of the extension plate 2 19 by nuts. It is set parallel to the groove 16, and its surface is chrome-plated to improve wear resistance and smoothness and reduce sliding friction with the clamping plate 18.

[0022] The cylinder 15 is extended and fixedly connected to a clamping plate 18, which is slidably connected to a slide rod 17. The clamping plate 18 is a rectangular steel plate with a sliding sleeve at its bottom that matches the slide rod 17. The sliding sleeve and slide rod 17 are clearance-fitted to ensure smooth sliding. The clamping plate 18 is fixedly connected to the telescopic end of the cylinder 15 via a flange, ensuring a secure and stable connection. The inner wall of the clamping plate 18 is also lined with a rubber buffer pad, which, together with the clamping plate 22, forms an axial clamping effect on the tray, preventing axial displacement of the tray during surgery. A drive housing 4 is fixedly connected to one outer end of the U-shaped frame 8. A motor 29 is fixedly connected to the outer side of the drive housing 4. A worm gear 33 is installed inside the drive housing 4 through the output end of the motor 29. A worm wheel 32 is fixedly connected inside the drive housing 4 through the shaft 31. The worm wheel 32 and the worm gear 33 cooperate with each other. The drive housing 4 is a closed housing, fixed to the outside of the U-shaped frame 8 with bolts. It has a cavity inside to accommodate the worm wheel 32 and the worm gear 33, which serves as protection and dust protection. The motor 29 is a geared motor with low output speed and high torque. It is fixed to the mounting base on the outside of the drive housing 4 with bolts. The worm gear 33 is connected to the output end of the motor 29 with a key. The worm wheel 32 is fixedly sleeved on the shaft 31. The meshing transmission ratio of the worm wheel 32 and the worm gear 33 is designed to enable the support platform 6 to slowly and smoothly rotate, with a rotation angle range of 0-45°, meeting the operational needs of medical personnel.

[0023] A mounting bracket 26 is fixedly connected to one outer end of the base 1. A second motor 27 is fixedly connected to the top of the mounting bracket 26. The output end of the second motor 27 passes through the mounting bracket 26 and downwards is connected to a second pulley 20. A first pulley 11 is fixedly connected to the rotating shaft 12. A belt 28 is fitted onto the first pulley 11 and the second pulley 20. Universal wheels 2 are installed at four ends of the lower part of the base 1. A handle 3 is fixedly connected to the rear outer part of the base 1. The mounting bracket 26 is an L-shaped steel plate, which is fixed to the base 1 with bolts. The second motor 27 is a stepper motor, which can achieve precise speed adjustment, and is fixed to the top of the mounting bracket 26 with bolts. The first pulley 11 and the second pulley 20 are both synchronous pulleys, and the belt 28 is a synchronous belt, which has high transmission accuracy and no slippage, ensuring that the rotation angle of the first shaft 12 is precisely controllable. The universal wheels 2 are silent universal wheels with a braking function, which are fixed in the mounting holes below the base 1 with bolts, which facilitates the movement and fixation of the device. The braking mechanism is easy to operate and can quickly lock the universal wheels. The handle 3 is a cylindrical hollow tube with a non-slip rubber sleeve on the surface. It is welded and fixed to the base 1, making it comfortable to hold and easy for medical staff to push the device.

[0024] Working principle: When in use, medical staff move the tray to a suitable position using the handle 3 and the two universal wheels at the bottom. When the tray needs to be fixed, one end of the tray is first brought into contact with the clamp 22. The clamps 21 at the other two ends can rebound under the action of the spring 34, thereby elastically fixing the two ends of the tray. At this time, the tray is fixed by the three clamps. Finally, the cylinder 15 at the bottom is activated, which can drive the clamp 18 to slide on the slide bar 17, thereby achieving the final positioning and fixing of the tray body 7. This ensures the stability of the tray during the operating room nursing process and also facilitates subsequent removal, reducing the difficulty of operation for medical staff. When the entire fixing device needs to be raised or lowered, motor 24 starts and drives gear 25 to rotate. Since gear 25 meshes with rack 23 and is limited by column 30, the bracket 10 can drive the top fixing component to be raised or lowered, thus making it suitable for tray fixing in different scenarios and improving the applicability of the device. Secondly, in order to make it easier for medical staff to take out the medical instruments inside the tray body 7, motor 29 starts and drives worm gear 33 to rotate. Through meshing with worm wheel 32, the rotation of rotating frame 5 can be adjusted, thereby adjusting the angle of the upper fixing component. This allows the fixed tray body 7 to tilt to a certain extent and face the medical staff, making it easier for the medical staff to take out small medical instruments and improving the practicality of the device.

[0025] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
