[0003] A search revealed Chinese Patent Publication No. CN221845074U, which discloses a surgical fixation table for mouse dissection, relating to the technical field of surgical fixation tables. The table includes a worktable with two sets of supporting legs symmetrically arranged on the lower outer surfaces of both sides. Each set of supporting legs has a connecting ring on its lower outer surface, and each connecting ring has a pad on its lower outer surface. The supporting legs and pads are connected by the connecting rings. A fixing ring is provided on the upper outer surface of the worktable, and a dissecting plate is provided on the inner wall of the fixing ring. The worktable and the dissecting plate are connected by the fixing ring. The inner wall of the dissecting plate has four sets of sliding grooves, and each set of sliding grooves has a fixing block. This surgical fixation table for mouse dissection uses the fixing blocks to fix the limbs of a mouse placed on the dissecting plate, and the sliding grooves can be adjusted according to the mouse's body shape.

[0004] The aforementioned device, while able to fix the limbs of mice using components such as fixing blocks, requires sliding grooves to be made on the dissection board to accommodate the movement of the fixing blocks. During the dissection of mice, blood or other tissue fluids are generated, which may flow into the sliding grooves, increasing the difficulty of subsequent cleaning and disinfection of the dissection board and making it impractical. Therefore, a portable rodent dissection fixation device is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-3This utility model provides an embodiment of a portable rodent dissection and fixation device, comprising an installation component 1 for connecting various parts, a fixing mechanism 2 on both the left and right sides of the installation component 1 for connecting a fixing rope 3 and for adjusting the position of the fixing rope 3 to fix the rodent during dissection, a dissection tray 4 on the upper part of the installation component 1 for dissection, positioning rods 41 fixedly connected to the four corners of the bottom surface of the dissection tray 4 for limiting the position of the dissection tray 4, a fixing rope 3 on the upper part of the fixing mechanism 2, which is disposable and its length can be cut according to actual needs, with rope loops 31 at both ends of the fixing rope 3 for connecting with the fixing component 24 and the rodent limbs, the rope loop 31 on the side of the fixing rope 3 near the fixing component 24 is non-adjustable for easy removal after use, and the rope loop 31 on the side of the fixing rope 3 near the dissection tray 4 is adjustable so that the rope loop 31 can fix the limbs of rodents of different sizes.

[0019] Furthermore, the mounting assembly 1 includes a placement frame 11 for placing the dissecting tray 4. The four corners of the bottom surface of the placement frame 11 are each connected to a positioning sleeve 12 for connecting to the positioning rod 41. The positioning rod 41 is movably connected to the positioning sleeve 12. The mounting assembly 1 also includes multiple support legs 13 for supporting the placement frame 11. The support legs 13 are threadedly connected to the positioning sleeve 12 to facilitate the storage and carrying of the device.

[0020] like Figures 4-5 As shown, the fixing mechanism 2 includes a housing 21, which is used to connect various components. The housing 21 is fixedly connected to the placement frame 11. An adjusting rod 22 is rotatably connected through the middle of the housing 21. The front and rear parts of the adjusting rod 22 are respectively provided with threads in opposite directions, which are used to match the distance between the two sliders 23 to match the fixing rope 3 to fix the mouse. The slider 23 is slidably connected inside the housing 21, which is used to match the adjustment of the position of the fixing member 24. The adjusting rod 22 passes through and is threadedly connected to the slider 23. The top of the slider 23 is fixedly connected to the fixing member 24, which is used to match the limit of the rope loop 31.

[0021] Furthermore, the fixing member 24 includes a hollow column 241, which is used to connect various components. The hollow column 241 is fixedly connected to the slider 23. A pressure block 242 is provided on the upper part of the hollow column 241, which is used to cooperate with the hollow column 241 to press the rope loop 31 connected to the fixing member 24 to prevent the rope loop 31 from falling off. The pressure block 242 and the hollow column 241 are both fixedly connected to a limit ring 243, which may be made of rubber. A connecting rod 244 is fixedly connected to the bottom of the pressure block 242, which is used to connect various components. The connecting rod 244 passes through and slides through the hollow column 241. A connecting plate 245 is fixedly connected to the bottom of the connecting rod 244, which is used to cooperate with the connection of the spring 246 to cooperate with the reset of the pressure block 242. The connecting plate 245 and the hollow column 241 are both fixedly connected to the spring 246.

[0022] Working principle: When in use, first tighten the support leg 13 and the positioning sleeve 12 at the bottom of the placement frame 11, then place the installation component 1 in a suitable position through the support leg 13, then align the positioning rod 41 at the bottom of the dissection tray 4 with the placement frame 11 and insert it so that the dissection tray 4 is placed inside the placement frame 11, and place the wild rat to be dissected on the dissection tray 4.

[0023] Then, cut four pieces of fixed rope 3 of appropriate length, and tie fixed rope loops 31 and adjustable rope loops 31 to both ends of the fixed rope 3. The fixed rope loops 31 are fitted onto the fixing member 24. When the fixed rope loops 31 are connected to the fixing member 24, first pull the pressure block 242, which will cause the limiting ring 243, the connecting rod 244, and the connecting plate 245 connected to the connecting rod 244 to move. At this time, the connecting plate 245 will compress the spring 246, and the pressure block 242 will drive its lower limiting ring 243 away from the upper limiting ring 243 of the hollow column 241. The fixed rope loop 31 is secured between the pressure block 242 and the empty column 241. Then, the pressure block 242 is released. Under the elastic force of the spring 246, the spring 246 will push the connecting plate 245 to reset. The connecting plate 245 will drive the pressure block 242 to reset through the connecting rod 244. The limiting ring 243 under the pressure block 242 will press against the limiting ring 243 on the empty column 241, thereby clamping and fixing the fixed rope loop 31. Then, the adjustable rope loop 31 of the fixing rope 3 is put on the limb of the wild mouse. Pulling the rope loop 31 adjusts the tightness of the rope loop 31 so that the rope loop 31 can fix the limb of the wild mouse.

[0024] Once all four fixing ropes 3 are secured to the fixing parts 24 and the limbs of the wild mouse, immediately rotate the adjusting rod 22. This will cause the two sliders 23 connected to the adjusting rod 22 to move away from each other. At this time, the fixing parts 24 connected to the sliders 23 will also be moved away from each other, thereby tightening the fixing ropes 3 connected to the wild mouse and fixing the wild mouse in place. Then, the dissection of the wild mouse can be performed.

[0025] After the dissection of the wild rat is completed, the dissected wild rat can be removed from the dissection tray 4. Then, pull the pressure block 242 to remove the fixing rope 3 from the fixing part 24. Then, the dissection tray 4 can be taken out from the placement frame 11 and cleaned and disinfected. If it is necessary to store the device, simply loosen the support leg 13 from the positioning sleeve 12 and then store and place the various parts.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
