Description

Technical Field

[0001] The utility model relates to the technical field of operating table hydraulic systems, in particular to an electric hydraulic surgical operating table oil dialysis system. Background Art

[0002] Surgical operating tables are commonly used in hospitals, often requiring folding, bending, and lifting to accommodate the patient's desired surgical position and the surgeon's height. With the advancement of technology, electric-hydraulic surgical tables are increasingly being adopted by hospitals. These electric-driven hydraulic systems enable convenient, fast, and stable movement.

[0003] Hydraulic systems are typically equipped with filters to filter solid particles from the hydraulic oil to prevent these particles from wearing out the hydraulic equipment and reducing its service life. After a period of use, the filter needs to be replaced promptly to ensure effective filtration of the hydraulic oil. When removing the filter, it must be removed and set aside. This not only requires an additional container to store the old filter, but the old filter is prone to tipping over, causing contaminated oil to leak out. Furthermore, during the time it takes to replace the new filter, the oil in the pipes may drip, contaminating the operating room or operating table. Furthermore, when transferring the old filter, care must be taken to prevent the hydraulic oil from leaking out or splashing onto clothing, which is very inconvenient. Utility Model Content

[0004] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides an electric hydraulic surgical operating table oil dialysis system.

[0005] The technical solution of this utility model is as follows:

[0006] An electric hydraulic surgical operating table oil dialysis system includes an oil storage tank, an oil pump, a hydraulic device and a filtering mechanism connected by oil pipes;

[0007] The filtering mechanism includes a vertically arranged connector connected to the hydraulic device and the oil pump through an oil pipe, and a filter connected to the lower end of the connector through a rotating disassembly frame;

[0008] One end of the rotating disassembly frame is threadedly connected to the connector, and the other end extends horizontally, and the extension distance is greater than 1.5 times the maximum width of the filter;

[0009] The filter is slidably connected to the rotating disassembly frame and can slide out horizontally from both ends of the rotating disassembly frame. The rotating disassembly frame is configured to enable the filter to dock with the connector by rotating.

[0010] When replacing the filter, rotate the rotating disassembly frame to drive the old filter downward, then slide the new filter from the rotating connection end of the rotating disassembly frame into the rotating disassembly frame, and at the same time push the old filter to the end of the rotating disassembly frame away from the connector, then rotate the rotating disassembly frame again to drive the new filter upward and dock with the lower end of the connector to complete the filter replacement. The replacement operation is simple, convenient and fast.

[0011] In addition, the new and old filters can be seamlessly replaced to avoid oil dripping in the pipeline.

[0012] In addition, after the old filter is moved from under the connector, it remains connected to the rotating disassembly frame. After the filter replacement is completed, the old filter can be taken out. No additional storage container is required, and there is no problem of dumping the old filter.

[0013] Preferably, the rotating assembly and disassembly frame has an inverted U-shaped cross-section, with sliding portions provided on its inner sidewalls for slidingly connecting the filter. The top plate of the rotating assembly and disassembly frame is connected to a connector, the lower end of which is positioned within the U-shaped groove of the rotating assembly and disassembly frame. The lower ends of the two side plates of the rotating assembly and disassembly frame can extend downward to below the lower end of the connector, allowing the filter to slide under the connector.

[0014] Preferably, the sliding portion is a slide groove, and the upper end of the filter is provided with a protrusion that slides in cooperation with the slide groove.

[0015] Preferably, the sliding portion is located at the lower part of the rotating and disassembling frame, which can reduce the height of the rotating and disassembling frame, save materials, and reduce the weight of the rotating and disassembling frame.

[0016] In the present application, the end of the rotating disassembly frame away from the connecting head is at a distance of 1.5-2.5 times the maximum width of the filter from the rotating axis, so that when the old filter is moved away from under the connecting head, it can still be connected as a whole to the rotating disassembly frame to prevent it from falling, while at the same time it is not too long to take up space.

[0017] Furthermore, when the maximum width of the filter is equal to the width of the connector, the length of the rotating disassembly frame is preferably equal to 2-3 times the maximum width of the filter.

[0018] In order to prevent the dirty oil in the old filter from flowing out or splashing when the rotating disassembly frame is rotated or when it is taken out and taken away, a rotating support frame extending in the same direction as the old filter is provided in the rotating disassembly frame. One end of the rotating support frame is rotatably connected to the connecting head, and the other end is provided with an oil sealing cover, which can be buckled with the filter moved underneath it.

[0019] After the old filter is replaced by the new filter, it is moved under the oil seal cap. When the rotating disassembly frame is rotated, the rotating support frame rotates along with it. The old filter rises with the rotating disassembly frame, while the oil seal cap and the rotating support frame only rotate and do not move up. They come into contact with the rising old filter and snap onto the top of the old filter, sealing the old filter.

[0020] In the above solution, the oil seal cap is slidably connected to the rotating support frame and can slide out from the end of the rotating disassembly frame away from the connector. After the oil seal cap is engaged with the old filter, it is removed from the end of the rotating disassembly frame away from the connector by sliding.

[0021] Preferably, the minimum distance between the vertical center axis of the oil seal cover and the rotating axis of the rotating disassembly frame is equal to the maximum width of the filter, so that after the new filter pushes the old filter away, the old filter is just located under the oil seal cover, and there is no need to spend extra time to adjust the position of the old filter.

[0022] Preferably, the two ends of the rotating support frame are aligned with the two ends of the rotating disassembly frame to facilitate reinserting the oil sealing cover onto the rotating support frame.

[0023] The utility model provides an electric hydraulic surgical operating table oil dialysis system, which has the following beneficial effects:

[0024] 1. Disconnect the old filter from the connector by rotating the disassembly and assembly rack, then push the old filter out and replace it with the new filter. Then, rotate the disassembly and assembly rack in the opposite direction to complete the filter replacement. The operation is simple, convenient and quick.

[0025] 2. Seamless replacement of old and new filters can prevent oil dripping in the pipeline.

[0026] 3. After the old filter is moved from under the connector, it is still connected to the rotating disassembly frame. After the filter replacement is completed, the old filter can be taken out. No additional storage container is required, and there is no problem of dumping the old filter.

[0027] 4. When connecting the new filter to the connector, the old filter is fastened to the oil seal cap to prevent the dirty oil inside from flowing out or splashing out, so it can be safely removed and transferred. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] like Figures 1 to 3 As shown, an embodiment of the present invention provides an electric hydraulic surgical table oil dialysis system, comprising an oil tank 1, an oil pump 2, a hydraulic device 3, and a filter mechanism 4 connected by oil pipes. The oil tank 1 stores hydraulic oil, and the oil pump 2 supplies the hydraulic oil from the oil tank 1 to the hydraulic device 3. The hydraulic device 3 is used to drive the surgical table to perform the necessary movements, such as deformation, bending, and lifting. The used hydraulic oil is then delivered directly or again via another oil pump 2 to the filter mechanism 4. Finally, the filtered hydraulic oil flows back to the oil tank 1. In this system, multiple oil pumps 2 and hydraulic devices 3 can be provided, each operating independently and controlled by a control unit.

[0036] The filtering mechanism 4 comprises a vertically mounted connector 41, connected to the hydraulic device 3 and the oil pump 2 via oil pipes, and a filter 43 connected to the lower end of the connector 41 via a rotating assembly / disassembly frame 42. The connector 41 includes an oil inlet and an oil outlet, which communicate with the oil inlet and outlet at the top of the filter 43, respectively. The filter 43 is conventional and will not be described in detail here. In this embodiment, the connector 41 is preferably cylindrical, and the outer contour of the filter 43 is also preferably cylindrical. The oil outlet of the filter 43 is located at the top center, with the oil inlet arranged around the oil outlet.

[0037] One end of the rotating assembly and disassembly frame 42 is threadedly connected to the connector 41, and the other end extends horizontally, with the extension distance being greater than 1.5 times the maximum width of the filter 43. The filter 43 is slidably connected to the rotating assembly and disassembly frame 42 and can slide horizontally out from both ends of the rotating assembly and disassembly frame 42. The rotating assembly and disassembly frame 42 is configured to allow the filter 43 to dock with the connector 41 by rotation.

[0038] When the filter 43 is docked with the connector 41 , the vertical center axes of the filter 43 and the connector 41 and the rotation axis of the rotating assembly and disassembly frame 42 are collinear.

[0039] When replacing the filter 43, the rotating disassembly frame 42 is rotated to drive the old filter 43 downward; then the new filter 43 is slid into the rotating disassembly frame 42 from the end of the rotating connection of the rotating disassembly frame 42, and the old filter 43 is squeezed out when sliding in and pushed toward the end of the rotating disassembly frame 42 away from the connector 41. The length of the rotating disassembly frame 42 ensures that the old filter 43 is still supported by the rotating disassembly frame 42; then the rotating disassembly frame 42 is rotated in the opposite direction again to drive the new filter 43 upward and dock with the lower end of the connector 41, completing the replacement of the filter 43.

[0040] Specifically, the cross section of the rotating disassembly frame 42 is in an inverted U-shape, and sliding portions 421 are provided on the inner side walls of the rotating disassembly frame 42 for sliding connection with the filter 43 .

[0041] Specifically, one end of the top plate of the rotating assembly and disassembly frame 42 is provided with a circular hole, which is inserted into the connector 41 through this hole. The inner wall of the circular hole engages the cylindrical surface of the connector 41, thereby allowing the rotating assembly and disassembly frame 42 to rise or fall when it is rotated. The lower end of the connector 41 is located within the U-shaped groove of the rotating assembly and disassembly frame 42. The lower ends of the two side plates of the rotating assembly and disassembly frame 42 are lower than the lower end of the connector 41, and the sliding portion 421 is also positioned lower than the lower end of the connector 41, ensuring that the filter 43 always slides below the connector 41. The U-shaped interface structure also provides more stable support for the filter 43.

[0042] The sliding portion 421 is preferably a slide groove, and the upper end of the filter 43 is provided with a protrusion that slides with the slide groove. The protrusion is preferably annular and surrounds the filter 43 so that even if the filter 43 rotates, the filter 43 can always slide in the slide groove, so that when a new filter 43 is installed, there is no need to worry about the angle of the filter 43.

[0043] The sliding portion 421 is preferably located at the lower portion of the rotating and disassembling frame 42 , which can reduce the height of the rotating and disassembling frame 42 , save materials, and reduce the weight of the rotating and disassembling frame 42 .

[0044] The end of the rotating assembly and disassembly frame 42 away from the connector 41 is 1.5-2.5 times the maximum width of the filter 43 from the rotating axis of the rotating assembly and disassembly frame 42. This allows the old filter 43 to remain completely connected to the rotating assembly and disassembly frame 42 when removed from under the connector 41, preventing it from falling. At the same time, the old filter 43 is not too long to occupy space. In this embodiment, 1.5 times is preferred.

[0045] In this embodiment, the maximum width of the filter 43 is preferably equal to the width of the connector 41, that is, the two have the same diameter, and the length of the rotating disassembly frame 42 is preferably equal to 2-3 times the maximum width of the filter 43, preferably 2 times, that is, two filters 43 can be hung on the rotating disassembly frame 42, and it is also convenient to determine the correct position of the filter 43.

[0046] like Figure 2 and Figure 3 As shown, in order to prevent the dirty oil in the old filter 43 from flowing out or splashing when the rotating disassembly frame 42 is rotated, taken out and transferred, a rotating support frame 44 extending in the same direction as the rotating disassembly frame 42 is provided in the rotating disassembly frame 42. The rotating support frame 44 is preferably plate-shaped, and its two ends are aligned with the two ends of the rotating disassembly frame 42 respectively.

[0047] One end of the rotating support frame 44 is rotatably connected to the connector 41, and the other end is provided with an oil seal 45. The oil seal 45 is preferably slidably connected to the rotating support frame 44 and can be slid out from the end of the rotating and disassembling frame 42 away from the connector 41. The oil seal 45 can be engaged with the old filter 43 moved below it and, after engagement, can be removed by sliding from the end of the rotating and disassembling frame 42 away from the connector 41.

[0048] After the old filter 43 is replaced by the new filter 43, it is moved under the oil sealing cover 45. When the rotating disassembly frame 42 is rotated, the rotating support frame 44 rotates together, wherein the old filter 43 rises with the rotating disassembly frame 42, while the oil sealing cover 45 and the rotating support frame 44 only rotate and do not move up. Therefore, the rising old filter 43 contacts and engages with the oil sealing cover 45, sealing the old filter 43.

[0049] The minimum distance between the vertical center axis of the oil cover 45 and the rotating axis of the rotating disassembly frame 42 is preferably equal to the maximum width of the filter 43, so that after the new filter 43 squeezes out the old filter 43, the old filter 43 is just located below the oil cover 45. When the rotating disassembly frame 42 is rotated, the oil cover 45 and the old filter 43 are engaged with each other without interference problems, and there is no need to spend extra time adjusting the position of the old filter 43.

[0050] When replacing the filter 43 in the system of the present application, the replacement operation can be carried out by simply rotating the disassembly frame 42 and inserting the new filter 43. The operation is simple, convenient and quick, and the old and new filters 43 are seamlessly replaced, which can prevent oil dripping in the pipeline and contaminating the operating room and the operating table.

[0051] In addition, after the old filter 43 is moved away from the bottom of the connector 41, it is still connected to the rotating disassembly frame 42. After the filter 43 is replaced, the old filter 43 can be taken out. No additional storage container is required, and there is no problem of dumping the old filter 43.

[0052] Furthermore, when the new filter 43 is docked with the connector 41, the oil seal cap 45 can be fastened to the old filter 43, allowing the replacement user to safely remove and transfer the old filter 43 without worrying about the dirty oil in the old filter 43 leaking out. In addition, after cleaning, the oil seal cap 45 can be returned to the rotating support frame 44 for continued use.
