Description

Technical Field

[0001] This utility model relates to the technical field of mouse fixation, and in particular to a mouse fixation device. Background Technology

[0002] A mouse restraint is a tool used in animal experiments to immobilize mice, ensuring they maintain a relatively stable posture during experiments, facilitating various operations and observations by researchers. While existing mouse restraints can easily immobilize mice, such as their limbs, they may lack flexibility in adjustment, making them unsuitable for mice of different sizes and shapes. For example, some metal rod-type limb restraints use metal rods and clamps of fixed length at the four corners of a platform to immobilize the mouse's limbs. When dealing with smaller mice, the distance between the clamps and the rods cannot be reduced, causing the limbs to be overstretched, potentially leading to joint dislocations or muscle strains. Conversely, for larger mice, the rods may be too short, and the clamps may not effectively secure the limbs, allowing the mouse to struggle and move, making precise procedures such as footpad injections and experiments involving localized limb trauma difficult to perform. For example, some simple rope-binding limb restraints have non-adjustable rope lengths, which may result in either too tight or too loose bindings for mice with large differences in size, failing to provide adequate restraint. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mouse restraint device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The mouse restraint device includes a first plate, a second plate rotatably connected to the first plate, a through groove on the second plate, a double-ended screw rotatably connected to the through groove, multiple sets of frames threadedly connected to the double-ended screw, each set of frames slidably connected to the through groove, each set of frames threadedly connected to a first screw, and each set of first screws rotatably connected to a pressure plate.

[0006] Preferably, a threaded cylinder is connected to the first plate, a second screw is threadedly connected to the threaded cylinder, a slider is rotatably connected to the second screw, and a slide rail is slidably connected to one end and the other end of the slider, and multiple sets of slide rails are connected to the second plate.

[0007] Preferably, each of the multiple sets of frames has a vertical rod that can be moved through it, and each of the multiple sets of vertical rods is connected to a corresponding pressure plate.

[0008] Preferably, sponge pads are adhered to the corresponding end faces of the multiple sets of frames and pressure plates.

[0009] Preferably, one end of the second plate is connected to a column, and multiple sets of annular grooves are formed at the multiple sets of columns.

[0010] Preferably, a first handle is connected to the first screw, and a second handle is connected to one end and the other end of the double-ended screw.

[0011] Preferably, a third handle is connected to the second screw.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. By coordinating the first plate, second plate, through groove, double-ended screw, frame, first screw, and pressure plate, the double-ended screw drives the adjustment of the spacing between the two sets of frames. This allows for convenient placement of the two sets of frames at the limbs of mice of different sizes, according to the actual size of the mice. Simultaneously, the pressure plate is pressed down by the first screw to clamp and fix the limbs of the mice between the frame and the pressure plate, thus completing the fixation operation of the mouse limbs. This device can flexibly adapt to mice of different sizes within a certain range, improving the versatility of the fixture.

[0014] 2. By coordinating the first plate, second plate, screw, threaded cylinder, slider, and slide rail, the rotation of the screw at the threaded cylinder can drive the slider to move upward. In this way, the slider, in conjunction with the slide rail, can place the second plate at multiple angles around the center of the connection with the first plate, making it convenient for users to operate the mouse placed on the second plate at different angles.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1, referring to Figures 1 to 5 The mouse restraint device includes a first plate 1, a second plate 2 rotatably connected to the first plate 1, a through groove 3 on the second plate 2, a double-ended screw 4 rotatably connected to the through groove 3, and multiple sets of frames 5 threadedly connected to the double-ended screw 4. The double-ended screw 4 can drive the two sets of frames 5 to adjust the distance between them. All sets of frames 5 are slidably connected to the through groove 3. Each set of frames 5 is threadedly connected to a first screw 6, and a pressure plate 7 is rotatably connected to the first screw 6. The first screw 6 can drive the pressure plate 7 to move up and down, thus adjusting the distance between the pressure plate 7 and the corresponding surfaces of the frames 5 to fix the limbs of the mouse. By adjusting the two sets of frames 5, the clamping position of the frames 5 and the pressure plate 7 can be adjusted, which facilitates the limb restraint operation of mice of different sizes on the second plate 2.

[0023] In this embodiment, a threaded cylinder 8 is connected to the first plate 1, and a second screw 9 is threadedly connected to the threaded cylinder 8. A slider 10 is rotatably connected to the second screw 9, and slide rails 11 are slidably connected to one end and the other end of the slider 10. Multiple sets of slide rails 11 are connected to the second plate 2. By rotating the second screw 9, the threaded cylinder 8 can be raised and lowered, thus the second screw 9 can drive the slider 10 to move upward. The second screw 9 will drive the slider 10 to move synchronously. The slider 10, in conjunction with the slide rails 11, can lift one end of the second plate 2 to adjust the placement angle of the second plate 2, facilitating different angle operations on the mouse. Vertical rods 12 are movably inserted through multiple sets of frame bodies 5, and each set of vertical rods 12 is connected to a corresponding pressure plate 7. The vertical rods 12 are used to guide the lifting and lowering movement of the pressure plate 7, ensuring... The clamping plate 7 and the frame 5 work together to hold and fix the limbs of the mouse. Sponge pads 17 are glued to the corresponding end faces of multiple sets of frames 5 and clamping plates 7. The sponge pads 17 are used to replace the frames 5 and clamping plates 7 in contact with the limbs of the mouse, so as to avoid injury to the limbs of the mouse. One end of the second plate 2 is connected to a column 15. Multiple sets of annular grooves 16 are opened at multiple sets of columns 15. The annular grooves 16 are used to wind the rope. The rope can open the upper and lower jaws of the mouse. The first screw 6 is connected to a first handle 13. The first handle 13 is used to drive the first screw 6 to rotate. One end of the double-ended screw 4 is connected to a second handle 14. The second handle 14 is used to drive the double-ended screw 4 to rotate. The second screw 9 is connected to a third handle 18. The third handle 18 is used to drive the second screw 9 to rotate.

[0024] The working principle of this embodiment is as follows: First, rotate the second handle 14 according to the size of the mouse. This will cause the double-headed screw 4 to adjust the spacing between the two sets of frames 5. After the spacing is adjusted, place the anesthetized mouse on the second plate 2 and place the mouse's limbs on the corresponding sponge pads 17 of the frame 5. After placement, use the first handle 13 to rotate the corresponding first screw 6, and use the pressure plate 7 in conjunction with the corresponding frame 5 to clamp and fix the mouse's limbs, thus completing the mouse fixation operation. If it is necessary to open the mouse's mouth, tie ropes to different annular grooves 16 on the multiple sets of columns 15, and place one end of the rope in contact with the mouse's upper and lower jaws to open the mouse's mouth. If the mouse's placement angle is inconvenient for experimental operations, use the third handle 18 to move the second screw 9 upwards to lift the slider 10 upwards. The slider 10, in conjunction with the slide rail 11, allows the second plate 2 to be placed at multiple angles to facilitate experimental operations on the mouse at the required angles.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
