Description

Technical Field

[0001] This utility model relates to the field of dissection table technology, and in particular to a dual-position interchangeable lifting dissection table. Background Technology

[0002] Dissection tables are common tools in medical laboratories and operating rooms, primarily used for dissection, surgery, and research. Patent publication number CN212592553U discloses a lifting dissection table, whose main structure includes a base and a tabletop. The base has a storage cavity, and the tabletop is located within the storage cavity. Human specimens can be placed on the tabletop. A swing arm and a lever within the storage cavity support the tabletop, and the tabletop is raised or lowered by the swing arm. However, this lifting dissection table can only hold one human specimen at a time. During experiments and teaching, specimen replacement is necessary. Currently, the replacement method involves raising the tabletop to its highest point, above the top of the storage cavity, removing the tabletop, transferring the human specimen to a storage tank in the storage chamber, and then placing the new specimen on the tabletop and moving it to the lifting dissection table. This switching operation is very cumbersome, especially during teaching.

[0003] Patent application number 202311343775.4 discloses an intelligent double-layer box-type dissection table capable of interchangeable positions. This dissection table features a double-layer structure, allowing for the switching of two human specimens. However, the switching mechanism is relatively complex. First, the upper and lower box-type dissection tables slide horizontally in opposite directions to create a misalignment. After misalignment, they need to be locked. Then, a rotating mechanism rotates the tables 180° to allow them to switch positions. The switched tables then slide horizontally relative to each other to complete the final switching. This structure is quite complex, especially since the upper and lower box-type dissection tables need to slide horizontally in a misaligned manner to increase the rotation radius. The overall structure is complex, and the rotation also increases the size of the final dissection table, resulting in higher overall costs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a dual-position interchangeable lifting dissection table, which can better realize the interchange of the upper and lower positions of two human specimens, and the overall structure is simpler and more reasonable, and the interchange action is simpler.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a dual-position interchangeable lifting dissection table, including a dissection table body, the dissection table body being provided with a storage chamber, the upper end of the storage chamber being open, a side opening being provided on one side wall of the dissection table body, a side door being deflected and installed on the side wall of the dissection table body, which can swing to a horizontal position, the side door being positioned corresponding to the side opening to open or close the side opening, and lifting support rails being lifted and lowered on both opposite side walls of the dissection table body, the lifting support rails being driven vertically to lift and lower by a first lifting power device. A first specimen support plate is slidably installed between the two lifting support rails, and the first specimen support plate slides in and out of the side opening; a pair of cantilever arms are also vertically and vertically installed on one side wall of the dissection table body, the cantilever arms penetrate the corresponding side wall and extend into the storage chamber, the cantilever arms are driven to rise and fall by a second lifting power device, a second specimen support plate is installed between the pair of cantilever arms, the extension direction of the cantilever arms is the same as the extension direction of the lifting support rails, the distance between the two cantilever arms is less than the distance between the two lifting support rails, and the cantilever arms are located inside the corresponding lifting support rails.

[0006] As a preferred embodiment, the lifting dissection table is rectangular in shape, the side opening is located on one of the long side walls of the dissection table body, the cantilever is vertically and vertically mounted on another long side wall, and the lifting support rail is vertically and vertically slidably mounted on two short side walls.

[0007] As a preferred embodiment, the inner side of the side door is provided with a number of support rollers for supporting the bottom of the first specimen support platform.

[0008] As a preferred embodiment, a horizontal drive device is installed on the lifting support guide rail to drive the first specimen support platform to slide horizontally.

[0009] As a preferred embodiment, the horizontal drive device includes a horizontal drive motor fixed to the lifting support guide rail, a horizontal slider slidably installed inside the lifting support guide rail, a first specimen support platform fixed on the horizontal slider, a horizontal rack provided on the horizontal slider, and a drive gear meshing with the horizontal rack installed on the output shaft of the corresponding horizontal drive motor.

[0010] As a preferred embodiment, an L-shaped connecting plate is fixed on the horizontal slider, and the first specimen support plate is placed on the horizontal plate portion of the connecting plate and is detachably fixed by fasteners.

[0011] As a preferred embodiment, both ends of the second specimen support platform are provided with hanging slots, which are hung on the corresponding cantilever and can be detachably fixed by fasteners.

[0012] As a preferred embodiment, each first lifting power device includes a first drive motor and a first lead screw and nut mechanism. The first lead screw of the first lead screw and nut mechanism is rotatably mounted on the side wall of the dissection table body, and the first nut of the first lead screw and nut mechanism is fixedly mounted on the lifting connecting block. The lifting support guide rail is fixedly connected to the lifting connecting block. Two vertically extending first vertical guide rails are also provided on the side wall of the dissection table body. The two ends of the lifting connecting block are respectively slidably engaged with the first vertical guide rails through first lifting sliders. The first drive motor is drivenly connected to the first lead screw.

[0013] As a preferred embodiment, the cantilever includes a cantilever rod and a second lifting slider. A second vertically extending guide rail is provided on the side wall of the dissection table body. The second lifting slider is installed on the second vertical guide rail. The cantilever rod is fixed on the second lifting slider. The cantilever rod passes through the side wall and extends into the storage chamber. The hanging slot is hung on the corresponding cantilever rod. The second lifting power device includes a second drive motor and a second lead screw and nut mechanism. The second lead screw of the second lead screw and nut mechanism is rotatably installed on the side wall. The second nut of the second lead screw and nut mechanism is fixed to the cantilever rod. The second lead screw is driven by the second drive motor.

[0014] As a preferred embodiment, the upper end of the dissection table body is deflected and fitted with an auxiliary fixation plate for auxiliary fixation.

[0015] After adopting the above technical solution, the effect of this utility model is as follows: Since lifting support rails are installed vertically on both opposite side walls of the dissection table body, and these rails are driven vertically by a first lifting power device, a first specimen support plate is slidably installed between the two lifting support rails, and the first specimen support plate slides in and out of the side opening; a pair of cantilever arms are also vertically installed vertically on one side wall of the dissection table body, the cantilever arms penetrate the corresponding side wall and extend into the storage chamber, the cantilever arms are driven vertically by a second lifting power device, a second specimen support plate is installed between the pair of cantilever arms, the extension direction of the cantilever arms is the same as the extension direction of the lifting support rails, the distance between the two cantilever arms is less than the distance between the two lifting support rails, and the cantilever arms are located inside the corresponding lifting support rails; therefore, in use, human specimens are placed on both the first specimen support plate and the second specimen support plate, with the first specimen providing support. Taking the initial position of the platform as the top as an example, when the positions need to be interchanged, the side door can be opened, and then the first lifting power device drives the lifting support rail to rise and fall, so that the first specimen support platform aligns with the side opening. Then, the first specimen support platform slides out horizontally, making room for the storage chamber. At the same time, since the distance between the cantilever arms is less than the distance between the two lifting support rails and the cantilever arms are located inside the corresponding lifting support rails, the second specimen support platform between the cantilever arms can rise and fall smoothly. The second specimen support platform is supported by the cantilever arms and rises to the top position. At this time, the first specimen support platform can be pushed back into the storage chamber from the side opening. Then, the first lifting power device drives the lifting support rail to fall, thus completing the position switching of the upper and lower human specimens. The position change of this lifting dissection table is very fast, and the structure is simple and occupies little space. Due to the simple structure, the overall lifting dissection table has a lower failure rate and is more stable and reliable.

[0016] Furthermore, since the inner side of the side door is provided with several support rollers for supporting the bottom of the first specimen support platform, the support rollers can provide better support when the first specimen support platform slides out.

[0017] Furthermore, a horizontal drive device is installed on the lifting support guide rail to drive the first specimen support platform to slide horizontally. The horizontal drive device includes a horizontal drive motor fixed to the lifting support guide rail, a horizontal slider slidably installed inside the lifting support guide rail, the first specimen support platform fixed to the horizontal slider, and a horizontal rack on the horizontal slider. A drive gear meshing with the horizontal rack is installed on the output shaft of the corresponding horizontal drive motor. Therefore, without the horizontal drive device, manual operation is possible; however, with the horizontal drive device, the first specimen support platform can automatically enter and exit the side opening, resulting in a higher degree of automation.

[0018] Furthermore, since an L-shaped connecting plate is fixed on the horizontal slider, and the first specimen support plate is placed on the horizontal plate of the connecting plate and is detachably fixed by fasteners, the first specimen support plate can be removed from the connecting plate, thereby facilitating better cleaning of the storage chamber.

[0019] Furthermore, since both ends of the second specimen support plate are provided with hanging slots, which are hung on the corresponding cantilever and can be detachably fixed by fasteners, the second specimen support plate can also be easily assembled and fixed firmly by detachable fasteners. When disassembly is required, the fasteners can be removed and the second specimen support plate can be pulled out horizontally from the side opening. This makes disassembly convenient and also facilitates cleaning of the storage chamber.

[0020] Furthermore, since each first lifting power device includes a first drive motor and a first lead screw and nut mechanism, the first lead screw of the first lead screw and nut mechanism is rotatably mounted on the side wall of the dissection table body, the first nut of the first lead screw and nut mechanism is fixedly mounted on the lifting connecting block, the lifting support guide rail is fixedly connected to the lifting connecting block, and two vertically extending first vertical guide rails are also provided on the side wall of the dissection table body. The two ends of the lifting connecting block are respectively slidably engaged with the first vertical guide rails through the first lifting sliders, and the first drive motor is drivenly connected to the first lead screw. Therefore, when the first lifting power device drives the lifting connecting block to rise and fall, the two ends of the lifting connecting block are slidably mounted on the first vertical guide rails through the first lifting sliders, so that the lifting connecting block has guiding force at both ends and is more stable.

[0021] Furthermore, since the cantilever includes a cantilever rod and a second lifting slider, and a vertically extending second vertical guide rail is provided on the side wall of the dissection table body, the second lifting slider is installed on the second vertical guide rail, the cantilever rod is fixed on the second lifting slider, the cantilever rod passes through the side wall and extends into the storage chamber, the hanging slot is hung on the corresponding cantilever rod, and the second lifting power device includes a second drive motor and a second lead screw and nut mechanism. The second lead screw of the second lead screw and nut mechanism is rotatably installed on the side wall, and the second nut of the second lead screw and nut mechanism is fixed to the cantilever rod. The second lead screw is driven by the second drive motor. Therefore, the cantilever rod is slidably installed on the second vertical guide rail through the second lifting slider, ensuring smooth vertical lifting and sliding. At the same time, the cantilever rod is also provided with a second nut that cooperates with the second lead screw. Therefore, the cantilever rod is also guided and supported by the second lead screw and the second vertical guide rail, and the force on the cantilever rod is more reasonable.

[0033] The present invention will be further described in detail below through specific embodiments.

[0034] Example 1

[0035] like Figures 1 to 7As shown, a dual-position interchangeable lifting dissection table includes a dissection table body 1, which has a storage chamber with an opening at its upper end. A side opening 3 is located on one side wall of the dissection table body 1. A side door 2, which can swing to a horizontal position, is mounted on the side wall of the dissection table body 1. The side door 2 corresponds to the side opening 3, allowing the side opening 3 to be opened or closed. The lifting dissection table is rectangular in shape, and the side opening 3 is located on one of the long side walls of the dissection table body 1. In this embodiment, the swinging opening and closing of the side door 2 can be assisted by a gas spring 24.

[0036] Lifting support rails 13 are installed vertically on both opposite side walls of the dissection table body 1. The lifting support rails 13 are driven vertically by a first lifting power device. A first specimen support plate is slidably installed between the two lifting support rails 13. The first specimen support plate slides in and out of the side opening 3. A pair of cantilever arms are also vertically installed vertically on one side wall of the dissection table body 1. The cantilever arms pass through the corresponding side wall and extend into the storage chamber. The cantilever arms are driven vertically by a second lifting power device. A second specimen support plate 5 is installed between the pair of cantilever arms. The extension direction of the cantilever arms is the same as the extension direction of the lifting support rails 13. The distance between the two cantilever arms is less than the distance between the two lifting support rails 13, and the cantilever arms are located inside the corresponding lifting support rails 13.

[0037] The cantilever is vertically and vertically mounted on another long side wall, and the lifting support rail 13 is vertically and vertically slidably mounted on two short side walls.

[0038] Among them, such as Figures 2 to 7As shown, each first lifting power device includes a first drive motor 19 and a first lead screw 18 nut mechanism. The first lead screw 18 of the first lead screw 18 nut mechanism is rotatably mounted on the side wall of the dissection table body 1, and the first nut of the first lead screw 18 nut mechanism is fixedly mounted on the lifting connecting block 15. The first drive motor 19 is connected to the first lead screw 18 in a transmission manner. The first drive motor 19 is located below the first lead screw 18. The lifting support guide rail 13 is fixedly connected to the lifting connecting block 15. Two vertically extending first vertical guide rails 16 are also provided on the side wall of the dissection table body 1. The two ends of the lifting connecting block 15 are slidably engaged with the first vertical guide rails 16 via first lifting sliders 17. When the first drive motor 19 drives the first lead screw 18 to rotate, the first nut will rise and fall on the first lead screw 18 due to the thread engagement. Thus, the lifting connecting block 15 will move up and down along with the lifting support guide rail 13. Of course, a vertical slot 12 is provided on the side wall of the dissection table body 1 to facilitate the connection between the lifting connecting block 15 and the lifting support guide rail 13. In this embodiment, a lifting support rail 13 is provided on the short side wall. Therefore, the installation and driving method of each lifting support rail 13 is the same.

[0039] In this embodiment, a horizontal slider 20 is horizontally mounted on the lifting support guide rail 13. An L-shaped connecting plate 14 is fixed on the horizontal slider 20. The first specimen support platform is placed on the horizontal plate portion of the connecting plate 14 and is detachably fixed by fasteners. In this embodiment, the fasteners can be pins or bolts. The first specimen support platform can be fixed to the horizontal plate portion by vertically arranged pins or bolts, so that the first specimen support platform is supported when placed on the horizontal plate portion and moves up and down or horizontally with it. It also facilitates the removal of the first specimen support platform from the side opening 3.

[0040] In this embodiment, both ends of the second specimen support platform 5 are provided with hanging slots, which are hung on the corresponding cantilever and detachably fixed by fasteners. The cantilever includes a cantilever rod 6 and a second lifting slider 8. A vertically extending second vertical guide rail 7 is provided on the side wall of the dissection table body 1. The second lifting slider 8 is installed on the second vertical guide rail 7. The cantilever rod 6 is fixed on the second lifting slider 8. A vertical slot 12 is provided on the long side wall. The cantilever rod 6 passes through the vertical slot 12 of the side wall and extends into the storage chamber. The hanging slot is hung on the corresponding cantilever rod 6. The second lifting power device includes a second drive motor 11 and a second lead screw 10 nut mechanism. The second lead screw 10 of the second lead screw 10 nut mechanism is rotatably installed on the side wall. The second nut 9 of the second lead screw 10 nut mechanism is fixed to the cantilever rod 6. The second lead screw 10 is driven by the second drive motor 11. The second lead screw 10 and the second vertical guide rail 7 are located on both sides of the suspension rod, which makes the force on the suspension rod more even.

[0041] In this embodiment, the upper end of the dissection table body 1 is deflected and equipped with an auxiliary fixing plate 4 for auxiliary fixation. The auxiliary fixing plate 4 can be deflected to a suitable position to assist in placing the arm supporting the human specimen.

[0042] In this embodiment, in order to better support the first specimen support platform, a number of support rollers are provided on the inner side of the side door 2 to support the bottom of the first specimen support platform. When the first specimen support platform is moved out from the side opening 3, the support rollers can better support the first specimen support platform, making it easier for the first specimen support platform to enter and exit smoothly.

[0043] Example 2

[0044] The structure of this embodiment is basically the same as that of embodiment 1, except that in this embodiment, the sliding of the first specimen support plate is not done in manual mode but in automatic mode.

[0045] A horizontal drive device is installed on the lifting support guide rail 13 to drive the first specimen support platform to slide horizontally.

[0046] Among them, such as Figure 8 and Figure 9As shown, the horizontal drive device includes a horizontal drive motor 23 fixed to the lifting support guide rail 13. A horizontal slider 20 is slidably installed inside the lifting support guide rail 13. The first specimen support platform is fixed to the horizontal slider 20. The horizontal slider 20 is provided with a horizontal rack 21. A drive gear 22 that meshes with the horizontal rack 21 is installed on the output shaft of the corresponding horizontal drive motor 23. In this embodiment, the lifting support guide rail 13 is a grooved guide rail. The horizontal drive motor 23 is fixed to the upper plate of the grooved guide rail. The output shaft of the horizontal drive motor 23 is arranged downward and the drive gear 22 is fixed thereon. A notch is provided in the groove of the lifting guide rail. The horizontal slider 20 is located in the groove of the lifting support guide rail 13 and is provided with a horizontal rack 21. The drive gear 22 extends into the notch and meshes with the horizontal rack 21.

[0047] When the horizontal drive motor 23 starts, the drive gear 22 rotates, which drives the horizontal rack 21 to move horizontally. Since the horizontal rack 21 is fixed to the horizontal slider 20, it can drive the horizontal slider 20 to move horizontally. The first specimen support plate is fixed on the horizontal slider 20, thus completing the horizontal drive of the first specimen support plate, which can replace manual operation.

[0048] The working principle of this lifting dissection table is: Figure 1 Taking the state as an example, Figure 1 In this configuration, the cantilever rod 6 is positioned above the lifting support rail 13, thus placing the second specimen support platform 5 above the first specimen support platform. In this way, the human specimens placed on the second specimen support platform 5 are used for experimental teaching. When a human specimen on the first specimen support platform is needed for teaching, the first drive motor 19 is activated after the side door 2 is opened. This drives the lifting support rail 13 to rise via the first lead screw 18 and nut mechanism, aligning the first specimen support platform with the side opening 3. Then, the first specimen support platform is moved horizontally on the lifting support rail 13 manually or automatically, thus removing the first specimen support platform. After it is removed, the second drive motor 11 is activated, causing the second specimen support platform 5 to descend. Since the distance between the cantilever arms is less than the distance between the lifting support rails 13, the cantilever arms can pass through the lifting support rails 13, allowing the second specimen support platform 5 to descend to the bottom. Then, the first specimen support platform slides back into the storage chamber through the side opening 3. Finally, the first drive motor 19 drives the first specimen support platform to rise to the appropriate position. This process allows for the switching of two human specimens, and the entire switching process is simple and reliable.

[0049] The above-described embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Any modifications and alterations to the technical solution of the present utility model without departing from its design spirit shall fall within the protection scope defined by the claims of the present utility model.
