Description

Technical Field

[0001] This utility model relates to the field of operating table technology, and more specifically, to an all-terrain surgical operating table. Background Technology

[0002] With the continuous development of modern medical technology, surgery, as an important means of treating diseases, places increasingly higher demands on surgical equipment. Especially in special environments such as field rescue and battlefield medicament, the portability, adaptability, and intelligence of surgical equipment are paramount. In the field, unstable ground conditions can cause the operating table to become unstable, thus affecting the accuracy and safety of the surgery.

[0003] Chinese invention patent application number 202410384489.0 discloses an all-terrain robotic arm-assisted surgical table. The table has rollers arranged in different directions at the bottom. The height of the rollers can be adjusted by a threaded rod, so as to adapt to different ground environment requirements and maintain the level of the table surface. However, when the ground height difference is large, the threaded rod needs to be rotated many times, which is cumbersome when adjusting it. In addition, the operating table is supported by rollers, and its contact with the ground is not good on uneven ground such as mountains and gravel, which may cause slippage, lifting and other situations, affecting the surgical operation.

Detailed Implementation

[0020] It should be noted that, where there is no conflict, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art described in this application.

[0022] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0023] Please see Figure 1-5 The present invention provides the following technical solution:

[0024] An all-terrain surgical table includes a base 1, with a plurality of rollers 4 evenly installed on the bottom of the base 1. A bed surface 5 is fixed on the top of the base 1. A plurality of height adjustment components 2 are evenly installed on the base 1. Support legs 3 are installed at the bottom of the height adjustment components 2. When moving, the support legs 3 are retracted, and the base 1 contacts the ground through the rollers 4, which can facilitate the movement of the surgical table. When it is necessary to fix it, the support legs 3 are lowered to contact the ground through the height adjustment components 2, thereby preventing the surgical table from moving and facilitating the operation.

[0025] The support leg 3 includes a second cylinder 34, which contains an air chamber 35. A screw 32 is threadedly connected to the top of the second cylinder 34. One end of the screw 32 extends into the air chamber 35 and is sealed to the air chamber 35. The other end of the screw 32 extends upward out of the second cylinder 34. A connecting block 31 is rotatably connected to the end of the screw 32 that extends out of the second cylinder 34. A second handle 33 is provided on the screw 32. The second handle 33 is located between the second cylinder 34 and the connecting block 31. Pushing the second handle 33 can drive the screw 32 to rotate, thereby adjusting the length of the screw 32 extending into the air chamber 35.

[0026] The air chamber 35 is connected to several slides 36 below, and support rods 37 are slidably connected in the slides 36. One end of the support rod 37 facing the air chamber 35 is sealed to the slide 36, and the other end of the support rod 37 can extend out of the slide 36. When the screw 32 moves downward, it squeezes the air chamber 35, thereby pushing the support rods 37 downward until all the support rods 37 are in contact with the ground. At this time, turning the handle 33 requires overcoming the overall weight of the operating table. That is, when the resistance increases sharply, all the support rods 37 simultaneously come into contact with the ground. Regardless of the ground conditions, it can provide stable support for the operating table.

[0027] The height adjustment assembly 2 includes a cylinder 21, the outer wall of which is slidably connected to the connecting block 31, and a piston 26 is slidably connected inside the cylinder 21. The piston rod of the piston 26 extends downward out of the cylinder 21 and is fixed on the connecting block 31. When the piston 26 moves, it can drive the support leg 3 to move synchronously.

[0028] The piston 26 divides the interior of cylinder 21 into a rod chamber 23 and a rodless chamber 24. The rod chamber 23 is located on one side of the piston rod through which the piston 26 passes. A through pipe 25 is provided inside cylinder 21. One end of the through pipe 25 is connected to the bottom of the rod chamber 23, and the other end of the through pipe 25 is connected to the top of the rodless chamber 24. A valve plate 27 is sealed at the opening of the through pipe 25 in the rodless chamber 24. A connecting rod 28 is provided on the side of the valve plate 27 away from the piston 26. The connecting rod 28 extends away from the piston 26 and extends out of cylinder 21.

[0029] Cylinder 21 is filled with high-pressure gas. The gas pressure in the rod chamber 23 and the rodless chamber 24 is equal. The gas in the rod chamber 23 tends to push the rod chamber 23 downward, and the gas in the rodless chamber 24 tends to push the rodless chamber 24 upward. That is, the effective working area of ​​the rod chamber 23 is the lower surface, and the effective working area of ​​the rodless chamber 24 is the upper surface. When the effective working area of ​​the rodless chamber 24 is set to be greater than the effective working area of ​​the rod chamber 23, the connecting rod 28 and the valve plate 27 on it are pressed down. When the passage pipe 25 is opened, under the action of gas pressure, cylinder 21 moves upward relative to piston 26. Cylinder 21 is fixed on the base 1, and piston 26 has space to move downward. Therefore, during adjustment, piston 26 drives the support foot 3 to move downward until the cylinder 34 of the support foot 3 is close to the ground.

[0030] When it is necessary to retract the support leg 3, the connecting rod 28 needs to be pressed down to open the valve plate 27, while the support leg 3 is pushed up or the corresponding position of the base 1 is pressed down.

[0031] Cylinder 21 penetrates the base 1. Several mounting blocks 22 are provided on the outer wall of cylinder 21. The mounting blocks 22 abut against the upper and lower end faces of the base 1 respectively. A handle 29 is rotatably connected to one end of cylinder 21 on the base 1. A connecting rod 28 is movably connected to one end of handle 29. By using a lever, the connecting rod 28 can be easily pushed down by turning handle 29.

[0032] Specifically, a second cylinder 34 is installed inside the support leg 3. A screw 32 is installed at the upper end of the second cylinder 34. One end of the screw 32 inside the second cylinder 34 is sealed to the second cylinder 34. Several slides 36 are opened at the bottom of the second cylinder 34. A support rod 37 is slidably connected in the slides 36. The upper end of the support rod 37 is sealed to the slides 36. By adjusting the length of the screw 32 extending into the second cylinder 34, the extension and retraction of the support rod 37 can be controlled. All slides 36 are connected. The support rod 37 is pushed out until it abuts against the ground. That is, the extension length of the support rod 37 can be adaptively adjusted according to the actual ground conditions, so that each support rod 37 can provide stable support and has stronger adaptability to the terrain.

[0033] The height adjustment component 2 is a cylinder structure. By turning the handle 29, the valve plate 27 moves down, opening the through pipe 25. The rodless chamber 24 is connected to the rod chamber 23, and the piston 26 moves down, bringing the support foot 3 close to the ground. When the handle 29 is stopped, the piston 26 stops moving, making adjustment convenient.
