Description

Technical Field

[0001] The utility model relates to the design and application field of a surgical tray vehicle, more specifically to a medical surgical tray vehicle which is convenient to adjust and use. Background Art

[0002] In the clinical work of the operating department, when the patient undergoes surgery, the medical staff needs to push the surgical tray cart containing various surgical instruments, utensils, and medicines to the operating bedside, so that the surgeon can choose to use them according to the specific circumstances of the operation.

[0003] The existing surgical tray cart has a relatively simple structure, and can generally realize functions such as lifting, rotating, and placing trays. For example, the Chinese patent: A surgical room tray cart, the authorization announcement number is: CN209301321U. This patent document discloses the specific structure and use of the surgical tray cart in the prior art. From the above-mentioned patent documents, it can be seen that in the prior art, the surgical tray cart often needs to adjust its height when in use to make it more convenient for the surgeon to take it, and it is also better suitable for different operating bed heights. However, in the prior art, when adjusting the height, the telescopic rods on both sides of the pallet cart are adjusted, that is, when in use, the fixing parts are first unscrewed and loosened, and then the height of the pallet rack is lifted and lowered. After confirming the height, the telescopic rods are again limited and fixed to complete the height adjustment operation.

[0004] The above existing height adjustment method of pallet truck has the following disadvantages in actual use:

[0005] Disadvantage 1: When there are many objects on the pallet truck, the weight of the pallet is relatively large. When the fixings are loosened and unscrewed, the pallet rack will be pressed down by the weight of the pallet, causing certain dangers. At the same time, when it is raised upward for adjustment, a lot of force is required to lift the entire pallet rack, which is inconvenient to adjust and use.

[0006] Disadvantage 2: When fixing, the telescopic rods on both sides are not fixed at the same time. One side is fixed first, and then the other side. This will also cause different heights on both sides and cause a certain tilt.

[0007] Disadvantage three: The size of the tray rack cannot be adjusted. Only medical trays of fixed sizes can be placed on the tray rack. Medical trays of different sizes cannot be placed on the tray rack, which has great limitations when used.

[0008] This technical solution is based on the structure of the existing medical surgical tray trolley, and further improves and perfects the structure of the existing surgical tray trolley. It can not only easily realize the height adjustment of the tray trolley, but also has higher precision in height lifting and lowering adjustment, and the adjustment process is more stable and easy, which is very convenient for medical staff to adjust and use. At the same time, it can be used to place and fix trays of different sizes, improving the applicability and usability of the tray trolley. Utility Model Content

The left and right sides of the chassis 2 are respectively provided with columns 3, and a lifting drive mechanism 4 is mounted between the upper parts of the two columns 3. A placement plate 5 is connected to the upper part of the lifting drive mechanism 4, and the lifting drive mechanism 4 can drive the placement plate 4 to move up and down. The lifting drive mechanism 4 includes: a screw body 41, a driving wheel 42, a slider 43, a connecting rod 44 and a fixed connecting block 45. The screw body 41 is mounted between the two columns 3. The driving wheel 42 is mounted at one end of the screw body 41. The driving wheel 42 can drive the screw body 41 to rotate. The screw body 41 is provided with a thread 411. The thread 411 located on the left side of the screw body 41 is a forward thread, and the thread 411 located on the right side of the screw body 41 is a reverse thread. There are two sliders 43, which are respectively mounted on the threads 411 on the left and right sides of the screw body 41. The rotation of the screw body 41 drives the two sliders 43 to slide and move; the fixed connecting block 45 is fixedly mounted in the middle of the bottom of the placement plate 5. The two ends of the connecting rod 44 are respectively connected to the fixed connecting block 45 and the slider 43. The connecting rod 44 can drive the placement plate 5 to move up and down under the drive of the slider.

[0028] The front and rear side walls of the slider 43 are respectively provided with mounting positions 431, and the end of the connecting rod 44 is provided with a mounting hole 441, and the mounting hole 441 is mounted at the mounting position 431. The front and rear side walls of the fixed connection block 45 are respectively provided with the mounting positions 431, and there are two mounting positions 431 on each side wall, which are symmetrically distributed. The two ends of the connecting rod 44 are rotatably connected, and the connecting rod 44 can be displaced along with the slider 43. By setting up a lifting drive mechanism 4, the screw body 41 is used to drive the left and right sides to slide outward and inward on the slider 43 at the same time, and the placing plate 5 can be driven to lift and move in the upper and lower directions through the connecting rod 44, thereby realizing the lifting and moving adjustment of the surgical tray vehicle. The entire adjustment process is not only convenient to operate, but also has higher adjustment accuracy and stability, and is safer and more practical.

[0029] like Figures 1 to 5As shown, an adjustable tray clamp 6 is provided on the upper surface of the placement plate 5, and a tray body 7 is placed on the surface of the placement plate 5 in a movable manner. The tray clamp 6 is fixed to the two outer side walls of the tray body 7 in a movable clamping manner. The tray clamp 6 is in the shape of an inverted "7", and a strip-shaped mounting hole 61 is provided on the tray clamp 6. A fixing bolt 62 is provided through the strip-shaped mounting hole 61. There are four tray clamps 6, which are in a group of two. Each group is symmetrically arranged on the placement plate 5, and the tray body 7 is clamped between two tray clamps 6. By arranging an adjustable tray clamp 6 on the upper surface of the placement plate 5, the clamping position of the tray clamp 6 can be adjusted to be suitable for the clamping and fixing of tray bodies 7 of different sizes, thereby improving the usability and applicability of the surgical tray vehicle.

[0030] When using:

[0031] Tray placement of surgical tray cart:

[0032] According to the size of the pallet body, first loosen the fixing bolts 62 on the pallet clamp 6, then move the position of the pallet clamp 6, and after confirming the position, re-tighten the fixing bolts 62 in the strip mounting holes 61 to complete the position adjustment of the pallet clamp 6, and finally place the pallet body 7 between the pallet clamps 6, with the upper part of the pallet clamp 6 elastically clamped on the outer wall of the pallet body 7.

[0033] Height adjustment of surgical tray trolley:

[0034] When the height of the surgical tray trolley needs to be raised: the driving wheel 42 is rotated clockwise, and the driving wheel 42 drives the screw body 41 to rotate clockwise, and the two sliders 43 on the screw body 41 slide inward synchronously in the same direction, and the sliding movement of the two sliders 43 drives the connecting rod 44 to move inward, and the inward movement of the connecting rod 44 drives the placement plate 5 to move upward, thereby completing the height adjustment of the surgical tray trolley;

[0035] When the height of the surgical tray cart needs to be lowered, the driving wheel 42 is rotated counterclockwise. At this time, the driving wheel 42 drives the screw body 41 to rotate counterclockwise, and the two sliders 43 on the screw body 41 slide synchronously outward in opposite directions. The sliding movement of the two sliders 43 drives the connecting rod 44 to move outward, and the outward movement of the connecting rod 44 drives the placement plate 5 to move downward, thereby completing the lowering adjustment of the surgical tray cart.

[0036] The above is only a specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial improvement of the utility model using this concept should be regarded as an infringement of the protection scope of the utility model.
