Description

Technical Field

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

[0002] Dissection tables are common tools in medical laboratories and operating rooms, mainly used for dissection, surgery, and research. Utility model patent 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 are installed within the storage cavity to support the tabletop, and the tabletop is raised or lowered by the swing arm. However, this type of lifting dissection table can only hold one human specimen. When conducting experiments and teaching, the human specimen needs to be changed. Currently, the only way to change it is to raise the table panel to its highest point, making it higher than the top of the storage chamber, and then remove the table panel. At this time, the human specimen needs to be transported to the storage pool in the storage room for storage. Then, the new human specimen is placed on the table panel and moved into the lifting dissection table. This switching operation is very cumbersome, especially during teaching. Therefore, when multiple human specimens are needed for teaching, multiple lifting dissection tables need to be placed in the laboratory, which increases the cost and occupies more space in the laboratory. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a dual-position lifting dissection table, which can store two human specimens and can switch the human specimens up and down, thereby better facilitating teaching experiments.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a dual-position 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, the side of the dissection table body being provided with a side opening, a horizontally arranged side support plate adapted to the side opening being installed on the outer side wall of the dissection table body, and a lifting support frame driven by a first lifting power device being lifted and lowered inside the dissection table body, the lifting support frame being used to place a specimen support plate, the lifting support frame being supported by a first lifting support rod, a second lifting support rod and a third lifting support rod at three points, wherein the first lifting support rod and the second lifting support rod are located at the first end of the lifting support frame, and the third lifting support rod is located at the second end of the lifting support frame;

[0005] The dissection table also includes a long guide rail driven by a second lifting power device and a short guide rail driven by a third lifting power device, which are parallel to each other and extend towards the side opening. The long guide rail is supported by a fourth and a fifth lifting support rod; the short guide rail is supported by a sixth lifting support rod. The short guide rail and the sixth lifting support rod correspond to the first end of the lifting support frame. The long and short guide rails cooperate to slide and support the specimen support platform. The specimen support platform on the long and short guide rails corresponds to the side opening and can slide onto the side support plate. The guide rail and the sixth lifting support rod are located on the side of the lifting support frame near the side opening, avoiding the lifting support frame; the long guide rail, the fourth lifting support rod, and the fifth lifting support rod are all located on the outer side of the second end of the lifting support frame; the short guide rail, the long guide rail, the fourth lifting support rod, the fifth lifting support rod, the sixth lifting support rod, the second lifting power device, and the third lifting power device avoid the lifting support frame and the specimen support platform on the lifting support frame; the first lifting support rod, the second lifting support rod, the third lifting support rod, and the first lifting power device avoid the specimen support platform inside the long guide rail and the short guide rail.

[0006] As a preferred embodiment, a sliding support frame for supporting the specimen support platform is also slidably installed within the short and long guide rails.

[0007] As a preferred embodiment, a horizontal drive device is installed on the short guide rail and / or the long guide rail to drive the sliding support frame in and out of the side opening.

[0008] As a preferred embodiment, the horizontal drive device includes a drive motor fixedly mounted on a short guide rail and / or a long guide rail, and the output shaft of the drive motor is connected to the side of the sliding support frame via a gear and rack transmission mechanism.

[0009] As a preferred embodiment, the side support plate is hinged to the outer wall of the dissection table body, and an opening and closing power device for driving the side support plate to open and close is provided between the side edge of the side opening and the side support plate. When the side support plate is closed, it swings to a vertical position and closes the side opening. When the side support plate is open, it is in a horizontal position and connected to the long guide rail and the short guide rail.

[0010] As a preferred embodiment, side baffles are provided on three of the sides of the side support plate. The height of the side baffles is higher than that of the side support plate and forms a semi-enclosed placement area. The other side of the placement area has an unclosed opening facing the side opening. The side baffles are provided with receiving grooves for accommodating the specimen support plate. The receiving grooves are adapted to the guide grooves in the long guide rail and the short guide rail.

[0011] As a preferred embodiment, when the specimen support platform moves to the side support plate, the specimen support platform is further supported by the short guide rail.

[0012] As a preferred embodiment, the first lifting power device is an electric push rod, and there are three electric push rods, which serve as the first lifting support rod, the second lifting support rod, and the third lifting support rod, respectively; there are two second lifting power devices, which are also electric push rods, and the third lifting power device is also an electric push rod, with each electric push rod serving as the fourth, fifth, and sixth lifting support rod.

[0013] As a preferred embodiment, the far end of the long guide rail is further provided with a limiting sealing plate that closes the guide rail groove of the long guide rail.

[0014] After adopting the above technical solution, the effect of this utility model is as follows: This dual-position lifting dissection table can store two human specimens. The specimens are placed on specimen support plates, one of which is placed on a lifting support frame, while the other is slidably installed between and supported by long and short guide rails. Under normal circumstances, the specimen support plates on the long and short guide rails are located within the storage chamber and above the lifting support frame, thus accommodating two human specimens. When a human specimen supported by the long and short guide rails needs to be used, the long and short guide rails can be raised using the second and third lifting power devices, thus raising the specimen support plate to the working position at the upper opening of the storage chamber, facilitating dissection teaching operations. When... When changing the lower human specimen, the long and short guide rails are driven downwards to connect the specimen support platform with the side support plate. The specimen support platform can then be pulled and slid onto the side support plate, thus avoiding the lifting support frame. At this point, the first lifting power device drives the lifting support frame to rise, placing the lower human specimen in the working position for convenient dissection teaching. Since the lifting support frame is now in the working position above the long and short rails, and its second end is only supported by the third lifting support rod, the specimen support platform on the side support plate can also be pushed into the storage chamber along the long and short guide rails, and then lowered for storage. After teaching, the first lifting power device drives the lifting support frame to descend for storage. This dual-position lifting dissection table can store two human specimens simultaneously and allows for easy switching between specimen positions, meeting the teaching needs of different specimens. It is more convenient overall, reduces the footprint of multiple dissection tables, and lowers costs.

[0015] Furthermore, a horizontal drive device is installed on the short and / or long guide rails to drive the sliding support frame to move in and out through the side opening. The horizontal drive device includes a drive motor fixedly mounted on the short and / or long guide rails. The output shaft of the drive motor is transmitted to the side of the sliding support frame via a gear and rack transmission mechanism. Therefore, the horizontal drive device can drive the sliding support frame to move in and out, achieving automatic switching between in and out. Simultaneously, the sliding support frame can better support the specimen support platform and facilitate transmission connection with the drive motor. The specimen support platform can also be easily moved out to replace different human specimens.

[0016] Furthermore, since the side support plate is hinged to the outer wall of the dissection table body, an opening and closing power device is provided between the side edge of the side opening and the side support plate to drive the side support plate to open and close. When the side support plate is closed, it swings to a vertical position and closes the side opening. When the side support plate is open, it is in a horizontal position and connected to the long guide rail and the short guide rail. In this way, the side support plate can be opened or closed, so that the side opening is closed during storage to meet the storage requirements.

[0017] Furthermore, since side baffles are provided on three of the sides of the side support plate, and the height of the side baffles is higher than that of the side support plate and forms a semi-enclosed placement area, the other side of the placement area has an unclosed opening facing the side opening. The side baffles are provided with receiving grooves to accommodate the specimen support platform. The receiving grooves are adapted to the guide rail grooves in the long guide rail and the short guide rail. Therefore, the side baffles can protect the sliding position of the sliding support frame, and the receiving grooves can accommodate the sliding of the sliding support frame, which facilitates better connection with the long guide rail and the short guide rail, and ensures accurate sliding action.

[0018] Furthermore, since the specimen support plate is supported by the short guide rail when it moves to the side support plate, when the specimen support plate slides out from the side opening onto the side support plate, part of the specimen support plate is inside the side opening and is supported by the short guide rail and the long guide rail. In this way, the width of the side support plate does not need to be too wide, so the side support plate occupies less space when flipped to the flat position.

[0019] Furthermore, since the first lifting power device is an electric push rod, and there are three electric push rods, which serve as the first lifting support rod, the second lifting support rod, and the third lifting support rod respectively; the second lifting power device has two electric push rods, and the third lifting power device is also an electric push rod, with each electric push rod serving as the fourth, fifth, and sixth lifting support rod. Therefore, the electric push rod can be used as a driving force and as a lifting and sliding structure. Moreover, the electric push rod can achieve self-locking, thus further simplifying the structure and reducing costs.

[0020] Furthermore, since the far end of the long guide rail is also provided with a limiting sealing plate that closes the guide rail groove of the long guide rail, the limiting sealing plate can limit the specimen support platform from sliding into the storage chamber to its limit, thus ensuring the accuracy of the position.

[0030] The present invention will be further described in detail below through specific embodiments.

[0031] like Figures 1 to 7As shown, a dual-position lifting dissection table includes a table body 1, which has a storage chamber 2 with an upper opening and a side opening 18 on its side. The storage chamber 2 is used for convenient storage of human specimens. An air extraction port connected to an air extraction system is also provided along the side edge of the upper opening of the storage chamber 2, facilitating air extraction during dissection experiments and teaching to prevent odors from rising and being smelled by the operator. The air extraction port and system are current standard features and are standard equipment on conventional dissection tables.

[0032] A horizontally arranged side support plate 4, adapted to the side opening 18, is installed on the outer side wall of the dissection table body 1.

[0033] The side support plate 4 can be directly fixed to the outer wall, so that the side opening 18 is always in an open state. This does not hinder the storage, lifting and lowering and position switching of the two human specimens. Of course, an additional insert plate can also be set to close the side opening for convenient storage.

[0034] In this preferred embodiment, the side support plate 4 is hinged to the outer wall of the dissection table body 1. An opening and closing power device 5 is provided between the side edge of the side opening 18 and the side support plate 4 to drive the side support plate 4 to open and close. When the side support plate 4 is closed, it swings to a vertical position and closes the side opening 18. When the side support plate 4 is open, it is in a horizontal position and connected to the long guide rail 9 and the short guide rail 7. The opening and closing power device 5 can be an electric cylinder, a linear motor, or a pneumatic cylinder, and preferably two are used. The two ends of the opening and closing power device 5 are respectively hinged to the inner side of the side edge of the side opening 18 and one end of the side support plate 4. The two opening and closing power devices 5 are connected to the two ends of the side support plate 4, and can effectively pull the side support plate 4 together to support the human specimen when in the horizontal position.

[0035] The dissection table body 1 is equipped with a lifting support frame 10 driven by a first lifting power device. The lifting support frame 10 is used to place the specimen support plate 3. The lifting support frame 10 is supported by three points: a first lifting support rod 11, a second lifting support rod 12, and a third lifting support rod 13. The first lifting support rod 11 and the second lifting support rod 12 are located at the first end of the lifting support frame 10, and the third lifting support rod 13 is located at the second end of the lifting support frame 10. The specimen support plate 3 can be a conventional specimen support plate 3, which can be supported by the lifting support frame 10. Therefore, the lifting dissection table of this embodiment has strong adaptability and does not require a customized plate.

[0036] The dissection table body 1 is also equipped with a long guide rail 9 driven by a second lifting power device and a short guide rail 7 driven by a third lifting power device. The long guide rail 9 and the short guide rail 7 are parallel to each other and extend toward the side opening 18. The long guide rail 9 and the short guide rail 7 cooperate with each other to slide and support the specimen support platform 3. In this embodiment, a sliding support frame 8 for supporting the specimen support platform 3 is also slidably installed in the short guide rail 7 and the long guide rail 9. In this way, the sliding support frame 8 can effectively support the specimen support platform 3, and the overall strength of the sliding support frame 8 can better support the specimen support platform 3. Therefore, it can also be adapted to conventional specimen support platforms 3.

[0037] In this embodiment, the dissection table is a rectangular dissection table. Therefore, the extension direction of the short guide rail 7 and the long guide rail 9 is the width direction, and the side opening 18 is provided on the side wall of the dissection table in the length direction.

[0038] The long guide rail 9 is supported by the fourth lifting support rod 14 and the fifth lifting support rod 15; the short guide rail 7 is supported by the sixth lifting support rod 16. The short guide rail 7 and the sixth lifting support rod 16 correspond to the first end of the lifting support frame 10. The specimen support platform 3 on the long guide rail 9 and the short guide rail 7 corresponds to the side opening 18 and can slide onto the side support plate 4.

[0039] The short guide rail 7 and the sixth lifting support rod 16 are located on the side of the lifting support frame 10 near the side opening 18, avoiding the lifting support frame 10; the long guide rail 9, the fourth lifting support rod 14, and the fifth lifting support rod 15 are all located on the outer side of the second end of the lifting support frame 10; the short guide rail 7, the long guide rail 9, the fourth lifting support rod 14, the fifth lifting support rod 15, the sixth lifting support rod 16, the second lifting power device, and the third lifting power device avoid the lifting support frame 10 and the specimen support platform 3 on the lifting support frame 10; the first lifting support rod 11, the second lifting support rod 12, the third lifting support rod 13, and the first lifting power device avoid the specimen support platform 3 inside the long guide rail 9 and the short guide rail 7.

[0040] like Figure 7 As shown, among which, Figure 7 Taking the top-down view as a reference, the first lifting support rod 11 and the second lifting support rod 12 are located outside the short guide rail 7. Figure 7 (On the top side of the drawing) In this way, the end of the sliding support frame 8 will not collide with the first lifting support rod 11 and the second lifting support rod 12 when the short guide rail 7 slides; at the same time, the short guide rail 7 and the sixth lifting support rod 16 are located on the right side of the lifting support frame 10. Therefore, when the sliding support frame 8 in the short guide rail 7 slides to the side support plate 4, the short guide rail 7 will not hinder the lifting of the lifting support frame 10.

[0041] And similarly, Figure 7As shown, the third lifting support rod 13 supports the lifting support frame 10, and the third lifting support rod 13 is located on the upper left side of the long guide rail 9 in the drawing, thus not obstructing the lifting of the long guide rail 9; the long guide rail 9, the fourth lifting support rod 14, and the fifth lifting support rod 15 are located below the lifting support frame 10, so that the long guide rail 9 and the lifting support frame 10 do not interfere with each other. Since the lower right corner of the lifting support frame 10 has no support and is in a suspended state, it does not obstruct the entry and exit of the sliding support frame 8 on the long guide rail 9 and the short guide rail 7.

[0042] In this embodiment, a horizontal drive device is installed on the short guide rail 7 and / or the long guide rail 9 to drive the sliding support frame 8 to enter and exit from the side opening 18.

[0043] like Figure 4 and Figure 5 As shown, the horizontal drive device includes a drive motor 6 fixedly mounted on the short guide rail 7 and / or the long guide rail 9. The output shaft of the drive motor 6 is connected to the side of the sliding support frame 8 via a gear and rack transmission mechanism. The rack 17 is fixed to the side wall of the sliding support frame 8, while the gear 19 is fixed to the output shaft of the drive motor 6. Preferably, in this embodiment, the drive motor 6 is fixed to both the short guide rail 7 and the long guide rail 9, and notches are provided on both the long guide rail 9 and the short guide rail 7 to facilitate meshing between the gear 19 on the output shaft of the drive motor 6 and the rack 17. A limiting sealing plate 91 is also provided at the far end of the long guide rail 9 to close the guide rail groove of the long guide rail 9. The limiting sealing plate 91 restricts the sliding limit position of the specimen support platform 3, avoiding the risk of slippage.

[0044] As shown in the figure Figure 1 , Figure 4 and Figure 5 As shown, side baffles 41 are also provided on three of the sides of the side support plate 4. The height of the side baffles 41 is higher than that of the side support plate 4 and forms a semi-enclosed placement area. The other side of the placement area has an unclosed opening facing the side opening 18. The side baffles 41 are provided with a receiving groove 42 for accommodating the specimen support plate 3. The receiving groove 42 is adapted to the guide grooves in the long guide rail 9 and the short guide rail 7. Preferably, when the specimen support plate 3 moves onto the side support plate 4, the specimen support plate 3 is assisted by the short guide rail 7. Then, when the sliding support frame 8 slides into the side support plate 4 within the long guide rail 9 and the short guide rail 7, it will directly enter the receiving groove 42, thereby ensuring the accuracy of the sliding position.

[0045] like Figures 3 to 5As shown, the first lifting power device is an electric push rod, and there are three electric push rods, which serve as the first lifting support rod 11, the second lifting support rod 12, and the third lifting support rod 13, respectively; there are two second lifting power devices, which are also electric push rods, and the third lifting power device is also an electric push rod, with each electric push rod serving as the fourth lifting support rod 14, the fifth lifting support rod 15, and the sixth lifting support rod 16.

[0046] In this embodiment, an electric push rod is used as a lifting support rod, which simplifies the structure. The electric push rod, with its self-locking function, can drive the specimen support platform 3 to rise and fall and stay at a specified height. The overall structure is more compact and the cost is lower.

[0047] Of course, other drive structures can also be used. For example, all the lifting support rods can be screw and nut mechanisms, and the first, second, and third lifting power devices can all be motors. The lifting of the specimen support platform 3 can also be achieved by using the motor to drive the screw and nut mechanism. Alternatively, a cylinder can be used as a linear power drive.

[0048] The working principle of this utility model is as follows: Figure 7 As shown, in the initial state, the lifting support frame 10 is at its lowest position, while the specimen support platform 3 on the long guide rail 9 and the short guide rail 7 is above the lifting support frame 10, thus accommodating the storage of two human specimens. The side support plate 4 closes the side opening 18, and the upper opening of the storage chamber 2 of the dissection table is also covered, thus sealing the entire structure for storage. At this time, when it is necessary to use the human specimen supported by the long guide rail 9 and the short guide rail 7, the upper cover of the dissection table is removed. The long guide rail 9 and the short guide rail 7 are respectively supported by the second lifting power device and the third lifting power device. The drive mechanism raises the plate to the top for easy experimental operation. When it is necessary to replace the human specimen below, the side support plate 4 is driven by the opening and closing power device 5 to deflect to a horizontal position. At this time, the side opening 18 is fully opened, and then the sliding support frame 8 on the long guide rail 9 and the short guide rail 7 descends to be flush with the side support plate 4. Then the drive motor 6 starts and drives the sliding support frame 8 to slide onto the side support plate 4 through the gear 19 and rack 17. In this way, the specimen support platform 3 on the sliding support frame 8 also enters the side support plate 4 and is supported by it.

[0049] Since the sliding support frame 8 and the specimen support platform 3 have entered the side support plate 4, and the short guide rail 7 is located on the outer side of the lifting support frame 10, while the long guide rail 9, the fourth lifting support rod 14, and the fifth lifting support rod 15 are located on the outer side of the second end of the lifting support frame 10, they all avoid the lifting support frame 10. At this time, the lifting support frame 10 is driven to rise to the upper opening by the first lifting power device. Then, the drive motor 6 starts again to slide the sliding support frame 8 on the side support plate 4 into the storage chamber 2. Similarly, the first lifting support rod 11 and the second lifting support rod 12 are located on the outer side of the end of the short guide rail 7, and one corner of the lifting support frame 10 is suspended. Therefore, the sliding support frame 8 on the long guide rail 9 and the short guide rail 7 can slide smoothly into the storage chamber 2. Then the long guide rail 9 and the short guide rail 7 descend to the lowest position, thus changing the position of the human specimen. When storage is needed, the lifting support frame 10 can be lowered directly for storage, and then the side opening 18 can be closed.

[0050] This lifting dissection table can freely switch the vertical position of human specimens to meet the teaching requirements of different human specimens. It is smaller in size, does not require frequent handling, and reduces the floor space required. One dissection table can meet the teaching and storage requirements of two specimens, and the overall cost is lower.

[0051] 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 made 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.
