Description

Technical Field

[0001] This invention relates to the field of aquatic dissection technology, specifically to a pufferfish dissection device. Background Technology

[0002] Pufferfish are marine and freshwater fish belonging to the family Tetraodontidae. They contain deadly toxins, primarily sodium tetrachloride (tetrodotoxin), which are found in their liver, ovaries, skin, and some internal organs.

[0003] Pufferfish are highly sought after for their delicate texture and unique taste, making them a popular food. In the scientific field, sodium tetrachloride, a neurotoxin, can be used as a research subject. Studying the biological mechanisms of this toxin can help scientists gain a deeper understanding of the processes of nerve transmission and nerve blockade. In addition, it can also help develop potential treatments for certain diseases.

[0004] During the dissection of pufferfish, the fish's skin is relatively smooth and soft, and some species have wart-like protrusions or small spines. Therefore, it is very easy for the fish to slip when physically grasped, requiring frequent movement of the fish for dissection. This results in low dissection efficiency. Furthermore, because pufferfish toxin is highly toxic, the slipping of the fish can cause the dissection tools to accidentally touch the fish's liver and ovaries, thus leading to the spread of toxins. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a pufferfish dissection device that solves the problem that, during dissection of pufferfish, the smooth and soft skin makes them prone to slipping, thus affecting dissection efficiency and causing toxin diffusion.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a pufferfish dissection device, comprising:

[0007] The base plate has a support installed in the middle of its top surface. Both sides of the support are rotatably connected to clamps. When the clamps on both sides are closed, they are used to hold the pufferfish. When the two clamps are opened, they are used to support the dissected pufferfish.

[0008] Movable side plates are provided on both sides of the outside of the support. Pressure plates are movably connected to the top of the side plates on the adjacent sides, and top plates are fixedly connected to the bottom of the side plates on the adjacent sides. When the pressure plates are close to the top plates, they can fix the head and tail of the dissected pufferfish. When the side plates move away from each other, the dissected pufferfish can open up.

[0009] Preferably, the contact surfaces of the clamps on both sides are provided with grooves, and multiple anti-slip strips are provided inside the grooves. Insert rods are fixed on the adjacent sides of the top plate and the pressure plate.

[0010] Preferably, the top of the side plate is threaded with a threaded rod, the bottom of the threaded rod is rotatably connected to the top surface of the pressure plate, and one side of the pressure plate is in contact with one side of the side plate.

[0011] Preferably, a collection box is provided on both sides of the top surface of the base plate, and a drain outlet is provided on the far side of the groove sidewall on both sides. The drain outlet is connected to the collection box, and the clamps on both sides are connected by a connecting plate. The connecting plate is made of waterproof and flexible material.

[0012] Preferably, a tray is installed on one side of the top surface of the base plate, and an installation rod is fixedly connected to the top surface of the base plate near the tray. Multiple bearing plates are installed on the outer wall of the installation rod. A support pipe is provided on the other side of the top surface of the base plate, and an arc-shaped tube is movably provided at the top of the support pipe, with the arc-shaped tube located above the clamping plate.

[0013] Preferably, the bracket is provided with a cover, the collection box is located outside the cover, the top surface of the base plate is provided with an installation groove, and the collection box, cover and bracket are all located on the bottom surface of the inner wall of the installation groove.

[0014] Preferably, an electric actuator is rotatably connected to both sides of the middle of the bottom surface of the inner wall of the mounting groove, and a connecting seat is movably provided at the output end of the electric actuator on both sides. The connecting seats on both sides are fixedly connected to the bottom surface of the clamping plates on both sides.

[0015] Preferably, a rotating shaft is installed on both sides of the top of the bracket, and a hinge seat is provided on one side of each of the two clamping plates, and the hinge seat is rotatably connected to the rotating shaft.

[0016] Preferably, an electric actuator two is installed in the middle of the bottom surface of the inner wall of the mounting groove. The output end of the electric actuator two is fixedly connected to a sliding plate. Both sides of the sliding plate are rotatably connected to inclined rods. The top of both inclined rods is rotatably connected to push plates. The far side of both push plates is fixedly connected to a top rod. The far side of both top rods is fixedly connected to the bottom of the near side of both side plates. The push plates are slidably connected to the bracket.

[0017] Preferably, the bottom of the bracket has an opening, the second electric push rod is located inside the opening, a slide rail is fixedly connected to the top surface of the inner wall of the opening, a slide groove is provided on the top of the push plate, the slide groove is slidably connected to the outer wall of the slide rail, and the cross-section of the slide rail and the slide groove are both T-shaped. Limiting grooves are provided in the middle of the inner walls on both sides of the opening, and the slide plate is slidably connected in the limiting groove.

[0018] Working Principle: During use, the second electric actuator pushes out the slide plate, causing it to move upwards and push the inclined rod. The inclined rod extends the two push plates away from each other, causing the two push plates to extend the top rod and move the side plates away from each other. This allows the pressure plate and top plate to move away from the clamping plate. Then, the first electric actuator extends its output end, pushing out the clamping plate. The clamping plates on both sides rotate along the pivot axis. When the clamping plates form a V-shape, the pufferfish is placed between the clamping plates, with its sides in the grooves and its belly facing upwards. The first electric actuator then extends its output end, closing the clamping plates and clamping the pufferfish. Anti-slip strips increase friction between the clamping plates and the pufferfish skin, preventing movement during dissection. Dissection can then begin. After dissection, the first electric actuator retracts its output end, causing the clamping plates to open away from each other. Once both clamping plates are horizontal, the pufferfish will... Contacting the top surface of the cover, the cover provides auxiliary support for the clamping plate. The dissected pufferfish can then be placed in the grooves on the two side clamping plates and flattened. The electric actuator retracts its output end, pulling the slide plate back so that the side plates are close to the clamping plate. The tail and head can then be placed on the top plate. The threaded rod is then rotated to push out the pressure plate, which will then be close to the top plate, clamping the head and tail. The insertion rod can then be inserted into the pufferfish's body. The electric actuator extends its output end, moving the two side plates away from each other. The dissected pufferfish can then be stretched and opened. During the dissection, waste liquid and debris can be discharged through the drain outlet and fall into the collection box. The extracted samples can be placed on the support plate, and tools can be placed on the tray. Water can also be guided through the branch pipe and arc pipe to rinse the pufferfish on the dissection table. The wastewater generated during rinsing can also be discharged through the drain outlet.

[0019] This invention provides a pufferfish dissection device. It has the following beneficial effects:

[0020] 1. This invention clamps the pufferfish by bringing two clamps close together, allowing for dissection. When the clamps are open, they support the dissected pufferfish. The top plate and clamps can clamp the head and tail of the fish respectively. By moving the side plates, the dissected pufferfish can be stretched and opened, thus preventing the pufferfish from slipping during dissection, improving dissection efficiency, and preventing the spread of toxins.

[0021] 2. The present invention can push out the pressure plate by rotating the threaded rod. At this time, the pressure plate will be close to the top plate. Both the pressure plate and the top plate are provided with insertion rods. Therefore, when the insertion rods are inserted into the body of the pufferfish, the pufferfish can be prevented from falling out between the pressure plate and the top plate, thus further preventing the pufferfish from slipping out.

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see the appendix Figure 1 , Figure 4 ,Figure 6 and Figure 7 This invention provides a pufferfish dissection device, comprising: a base plate 1, on which a support 2 is installed in the middle of its top surface; clamping plates 3 are rotatably connected to both sides of the support 2; the clamping plates 3 are used to hold the pufferfish when they are closed, and to support the dissected pufferfish when they are open; movable side plates 4 are provided on both sides of the support 2; pressure plates 5 are movably connected to the top of the adjacent sides of the side plates 4; and top plates 6 are fixedly connected to the bottom of the adjacent sides of the side plates 4. When the pressure plates 5 are close to the top plates 6, they can fix the head and tail of the dissected pufferfish; and when the side plates 4 are moved away from each other, the dissected pufferfish opens up.

[0035] By moving the side plates 4 away from the clamping plate 3, the clamping plates 3 can be rotated to bring them closer together. When the clamping plates 3 form a V-shape, place the pufferfish between the two clamping plates 3. Continue rotating the clamping plates 3 to bring them closer together, clamping the pufferfish tightly with its belly facing the opening 31 between the two clamping plates 3. The pufferfish can then be dissected. After dissection, open the two clamping plates 3. When both clamping plates 3 are horizontal, place the dissected pufferfish back in its place. Then move the side plates 4 so that the top plate 6 and... The clamping plate 5 is placed near the head and tail of the pufferfish. At this time, the clamping plate 5 is moved closer to the top plate 6, which can clamp the head and tail of the pufferfish. Finally, the side plate 4 is moved away from the clamping plate 3 to pull the dissected pufferfish open. The clamping of the pufferfish by the clamping plate 3, and the pulling of the dissected pufferfish by the side plate 4, clamping plate 5 and top plate 6 can prevent the pufferfish from slipping during dissection. Therefore, it is convenient to dissect the pufferfish. At the same time, it can also prevent the pufferfish from slipping and causing the dissecting instruments to accidentally hit the liver and ovaries, which could lead to the spread of toxins.

[0036] Please see the appendix Figure 1 , Figure 4 , Figure 6 , Figure 7 and Figure 8 The contact surfaces of both side plates 3 are provided with grooves, and multiple anti-slip strips 7 are provided inside the grooves. Insert rods 8 are fixed on the adjacent sides of the top plate 6 and the pressure plate 5. The top of the side plate 4 is threadedly connected to a threaded rod 9, the bottom of which is rotatably connected to the top surface of the pressure plate 5, and one side of the pressure plate 5 is in contact with one side of the side plate 4.

[0037] By setting grooves on clamping plate 3, clamping plate 3 can fit the body shape of pufferfish when clamping pufferfish, thereby improving the clamping effect. At the same time, after rotating threaded rod 9, pressure plate 5 can be pushed out, at which time pressure plate 5 can be inserted into top plate 6. As the two come closer to each other, insertion rod 8 will pierce the head and tail of pufferfish, thereby preventing pufferfish from slipping out between pressure plate 5 and top plate 6.

[0038] Please see the appendix Figure 1 , Figure 4 , Figure 5 and Figure 6 Collection boxes 10 are provided on both sides of the top surface of the base plate 1. Drainage outlets 11 are provided on the opposite sides of the groove sidewalls on both sides. The drainage outlets 11 are connected to the collection boxes 10. The two side plates 3 are connected by a connecting plate 12. The connecting plate 12 is made of waterproof and flexible material.

[0039] During dissection, the pufferfish's body fluids can flow into the collection box 10 from the drain 11. At the same time, the two clamps 3 are connected by the connecting plate 12 to prevent the pufferfish's body fluids and debris from entering between the two clamps 3. The connecting plate 12 can be made of polyethylene, polyvinyl chloride, polypropylene or polyurethane.

[0040] Please see the appendix Figure 1 and Figure 2 A tray 13 is installed on one side of the top surface of the base plate 1. An installation rod 14 is fixedly connected to the top surface of the base plate 1 near the tray 13. Multiple bearing plates 15 are installed on the outer wall of the installation rod 14. A branch pipe 16 is provided on the other side of the top surface of the base plate 1. An arc-shaped pipe 17 is movably provided on the top of the branch pipe 16. The arc-shaped pipe 17 is located above the clamping plate 3.

[0041] Before dissection, the necessary tools can be placed in tray 13, and the extracts to be obtained for dissection can be placed on support plate 15. At the same time, after connecting the water source to branch pipe 16, water can be allowed to enter arc pipe 17 along branch pipe 16. After the water is discharged from arc pipe 17, the dissected pufferfish can be cleaned, and the waste liquid generated during cleaning can flow into collection box 10 from drain outlet 11.

[0042] Please see the appendix Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 The bracket 2 is externally fitted with a cover 18, and the collection box 10 is located outside the cover 18. A mounting groove 19 is formed in the center of the top surface of the base plate 1. The collection box 10, cover 18, and bracket 2 are all located on the bottom surface of the inner wall of the mounting groove 19. Electric actuators 20 are rotatably connected to both sides of the center of the bottom surface of the inner wall of the mounting groove 19. Connecting seats 21 are movably mounted at the output ends of both electric actuators 20, and the connecting seats 21 are fixedly connected to the bottom surfaces of the two clamping plates 3. Rotating shafts 22 are installed on both sides of the top of the bracket 2, and hinge seats 23 are provided on one side of each clamping plate 3, with the hinge seats 23 rotatably connected to the rotating shafts 22.

[0043] By driving the electric actuator 20, the clamping plate 3 can be pushed out, and then rotated along the rotating shaft 22. At this time, the clamping plates 3 can be closed to clamp the pufferfish. After the electric actuator is retracted to the output end, both clamping plates 3 can be in a horizontal state. At this time, the clamping plates 3 will contact the cover 18. The cover 18 can provide auxiliary support for the clamping plates 3. At the same time, the cover 18 can also protect the electric actuator 20.

[0044] Please see the appendix Figure 1 , Figure 2 , Figure 7 , Figure 8 and Figure 10 An electric actuator 24 is installed in the middle of the bottom surface of the inner wall of the mounting groove 19. The output end of the electric actuator 24 is fixedly connected to a slide plate 25. Both sides of the slide plate 25 are rotatably connected to inclined rods 26. The top of both inclined rods 26 is rotatably connected to a push plate 27. The far side of both push plates 27 is fixedly connected to a top rod 28. The far side of both top rods 28 is fixedly connected to the bottom of the near side of both side plates 4. The push plate 27 is slidably connected to the bracket 2.

[0045] After the electric actuator 24 is driven, the slide plate 25 moves upward, which in turn pushes the inclined rod 26 to extend the push plate 27 and the push rod 28. The push rod 28 can drive the side plate 4, the pressure plate 5 and the top plate 6 away from the clamping plate 3. After the electric actuator 24 retracts its output end, it can drive the side plate 4, the pressure plate 5 and the top plate 6 closer to the clamping plate 3.

[0046] Please see the appendix Figures 7-10 The bottom of the bracket 2 has an opening 31, the electric push rod 24 is located in the opening 31, the top surface of the inner wall of the opening 31 is fixedly connected to the slide rail 29, the top of the push plate 27 has a slide groove 30, the slide groove 30 is slidably connected to the outer wall of the slide rail 29, and the cross section of the slide rail 29 and the slide groove 30 are both T-shaped. The middle of the inner wall on both sides of the opening 31 is provided with a limit groove 32, and the slide plate 25 is slidably connected in the limit groove 32.

[0047] The opening 31 at the bottom of the bracket 2 provides space for the installation of the electric push rod and the movement of the slide plate 25. The cross-section of the slide rail 29 and the slide groove 30 is set to a T-shape. Therefore, during the movement of the push plate 27, the slide rail 29 can guide its movement direction. At the same time, the push plate 27 can be locked onto the bracket 2, and the limiting groove 32 can guide the movement direction of the slide plate 25, thereby improving the stability of the device operation.
