Description

Technical Field

[0001] This utility model relates to the field of animal anatomy technology, and more specifically, to an animal anatomy table with a fixed structure. Background Technology

[0002] Animal dissection tables are important equipment for biomedical research, veterinary teaching, and pathological examination. Their functional design directly affects the efficiency and safety of dissection operations. However, when dissecting animals, the experimenters usually straighten the animal's limbs during the dissection process, which greatly affects the experimenters' ability to dissect.

[0003] The existing fixation devices for dissection tables generally adopt a fixed-point design, usually with only 4-6 preset fixation positions. This design is obviously insufficient when dealing with experimental animals of different sizes. For small rodents (such as mice and rats), the spacing between fixation points is too large, resulting in unstable fixation. When dissecting large animals (such as pigs and sheep), the existing fixation devices are not strong enough to bear the weight and lack multi-point fixation support. Utility Model Content

A snap-fit ​​groove 8 is provided inside the mounting rod 5, and snap-fit ​​blocks 9 are symmetrically slidably arranged on the snap-fit ​​groove 8. Snap-fit ​​springs 10 are provided between the snap-fit ​​blocks 9. A fixed seat 11 is hinged and rotatably mounted at the top of the mounting rod 5. A vertical groove 12 is provided on the fixed seat 11, and an adjusting roller 13 and a roller 14 are rotatably mounted within the vertical groove 12. A spring-loaded spring 15 is mounted on the roller 14, and an elastic band 16 is provided at one end of the spring-loaded spring 15. An elastic pull ring 17 is provided on the elastic band 16. One end of 14 is provided with an adjustment limiting device. A reset block 18 is slidably provided in the snap-fit ​​groove 8. The reset block 18 is provided with a reset groove 19 that cooperates with the snap-fit ​​block 9. A reset rod 20 is slidably provided on the mounting rod 5. One end of the reset rod 20 is fixedly connected to the reset block 18, and the other end is connected to a reset plate 21. A reset spring 22 is provided between the reset plate 21 and the mounting rod 5. The adjustment limiting device includes an adjustment rod 23. An adjustment groove 24 is provided on the adjustment roller 13. One end of the adjustment rod 23 is provided with an adjustment plate 25 in the adjustment groove 24.

A limiting hole 29 that cooperates with the limiting rod 28 is provided on the fixed seat 11. An adjustment spring 30 is provided between the adjustment plate 25 and the adjustment groove 24.

[0030] In this embodiment, when installing and using the fixture 4, the mounting rod 5 of the fixture 4 is inserted from the bottom of the operating table 1 into the mounting hole 3. The mounting spring 7 abuts against the bottom of the operating table 1. Simultaneously, the upper surface of the locking block 9 tilts, and under the squeezing action of the mounting hole 3, it retracts into the locking groove 8, squeezing the locking spring 10. When the locking block 9 completely passes through the mounting hole 3, it extends under the elastic force of the locking spring 10 and locks onto the upper surface of the operating table 1. Simultaneously, the downward elastic force of the mounting spring 7 causes the mounting plate 6 to lock onto the bottom surface of the operating table 1, fixing the fixture 4 in place. Then, the fixing base 11 is rotated, and the extension length of the elastic band 16 and elastic pull ring 17 is adjusted according to the animal's size. The limiting plate 26 is pulled outwards by the limiting handle 27. The limiting plate 26 causes the adjusting rod 23 and adjusting plate 25 to move outwards, stretching the adjusting spring 30, causing the limiting rod 28 to move away from the limit. The limiting handle 27 rotates the adjusting rod 23 and the adjusting roller 13, which in turn rotates the roller 14, releasing and retracting the elastic band 16 and the elastic pull ring 17. The elastic pull ring 17 secures the animal limbs. When the limiting handle 27 is released, the adjusting block moves the adjusting rod 23 and the limiting plate 26 under the elastic force of the adjusting spring 30, causing the limiting rod 28 to be inserted into the limiting hole 29, fixing the position of the adjusting roller 13 and the roller 14, thus completing the adjustment and fixing of the elastic band 16 and the elastic pull ring 17. When disassembling the fixture 4, the reset plate 21 is pressed, causing the reset rod 20 and the reset block 18 to move and compress the reset spring 22. The reset block 18 presses the snap-fit ​​block 9 through the reset groove 19, causing the snap-fit ​​block 9 to extend into the snap-fit ​​groove 8, thereby disassembling the fixture 4. After adjusting the position of the fixing seat 11, the fixture 4 is removed from below the mounting hole 3.

[0031] Please see Figures 1-2 As one embodiment of the collection box 2: the bottom of the operating table 1 is provided with a movable groove 31, one of the movable grooves 31 is rotatably provided with a movable screw 32, the movable screw 32 is threadedly connected to the collection box 2, and the other movable grooves 31 are provided with movable slide rods 33, the movable slide rods 33 are slidably connected to the collection box 2.

[0032] More specifically, the mounting hole 3 on the operating table 1 can not only be used to install the retainer 4, but also as a collection hole for the blood of dissected animals. By rotating the moving screw 32, the collection box 2 is moved along the moving slide bar 33, thereby adjusting the height of the collection box 2. When the collection box 2 is in a low position, it is convenient to install the retainer 4, and when the collection box 2 is in a high position, it is convenient to process the collected blood and clean the collection box 2.

[0033] In summary, when using or operating the overall equipment: When installing and using the fixing device 4, the mounting rod 5 of the fixing device 4 extends from the bottom of the operating table 1 into the mounting hole 3. The mounting spring 7 abuts against the bottom of the operating table 1. Simultaneously, the upper surface of the locking block 9 tilts, and under the squeezing action of the mounting hole 3, it retracts into the locking groove 8, squeezing the locking spring 10. When the locking block 9 completely passes through the mounting hole 3, it extends under the elastic force of the locking spring 10, locking onto the upper surface of the operating table 1. Simultaneously, the downward elastic force of the mounting spring 7 causes the mounting plate 6 to lock onto the bottom surface of the operating table 1, fixing the fixing device 4 in place. Then, rotate the fixing base 11, adjusting the extension length of the elastic band 16 and elastic pull ring 17 according to the animal's size. Pull the limiting plate 26 outward through the limiting handle 27. The limiting plate 26 causes the adjusting rod 23 and adjusting plate 25 to move outward, stretching the adjusting spring 30, causing the limiting rod... 28 leaves the limiting hole 29, and by rotating the limiting handle 27, the adjusting rod 23 and the adjusting roller 13 are driven to rotate. The adjusting roller 13 drives the roller 14 to rotate, releasing and contracting the elastic band 16 and the elastic pull ring 17. The elastic pull ring 17 fixes the animal limb. The limiting handle 27 is released, and the adjusting block drives the adjusting rod 23 and the limiting plate 26 to move under the elastic force of the adjusting spring 30. This drives the limiting rod 28 to be inserted into the limiting hole 29, fixing the position of the adjusting roller 13 and the roller 14, completing the adjustment and fixing work of the elastic band 16 and the elastic pull ring 17. When disassembling the fixture 4, the reset plate 21 is pressed. The reset plate 21 drives the reset rod 20 and the reset block 18 to move and compress the reset spring 22. The reset block 18 squeezes the snap-fit ​​block 9 through the reset groove 19, so that the snap-fit ​​block 9 extends into the snap-fit ​​groove 8, thereby disassembling the fixture 4. After adjusting the position of the fixing seat 11, the fixture 4 is taken out below the mounting hole 3.

[0034] The mounting hole 3 on the operating table 1 can not only be used to install the retainer 4, but also as a collection hole for the blood of dissected animals. By rotating the moving screw 32, the collection box 2 is moved along the moving slide bar 33, thereby adjusting the height of the collection box 2. When the collection box 2 is in a low position, it is convenient to install the retainer 4. When the collection box 2 is in a high position, it is convenient to process the collected blood and clean the collection box 2.
