Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a tool for modeling rats with periodontitis. Background Art

[0002] Periodontitis is a chronic inflammatory disease caused by bacterial infection in the oral cavity. It primarily affects periodontal supporting tissues such as the gums, periodontal ligament, and alveolar bone, ultimately leading to tooth loss. To study the pathogenesis, pathological changes, and treatments of periodontitis, scientists often use animal models to simulate the course of human periodontitis. Rats are a common experimental animal because their periodontal tissues share physiological and anatomical characteristics with humans, and they are smaller and easier to manipulate. In experiments using periodontitis models, rat fixation devices are crucial to ensure the smooth progress of the experiment, facilitating procedures such as surgery, imaging, and periodontal measurements. Current fixation devices typically use straps to secure the limbs of anesthetized rats. The length of the straps cannot be adjusted, and because different rats vary slightly in size, if the straps are too loose, the rats may move, resulting in unstable fixation. If they are too tight, blood circulation may be compromised, causing discomfort or injury. Utility Model Content

[0003] In response to the deficiencies in the prior art, the utility model provides a periodontitis rat modeling tool, which solves the problem in the prior art that the straps for fixing the rat's limbs cannot be fine-tuned, resulting in the fixation of the rat being easily too loose or too tight.

[0019] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1As shown, an embodiment of the present invention proposes a periodontitis rat modeling tool, including a base 1 and a fixing component. An operating table 2 is provided on the top of the base 1, and a jaw component is provided on the top of the operating table 2. The jaw component is used to open the rat's mouth. The fixing components are provided at the four corners of the top of the operating table 2. Each fixing component includes a fixing belt 3, one end of the fixing belt 3 is fixedly connected to the top of the operating table 2, and the other end of the fixing belt 3 is connected to a fixing rope 4. A movable channel is opened on the operating table 2, one end of each movable channel is connected to the top of the operating table 2, and the other end of each movable channel is connected to the side wall of the operating table 2. After the fixing rope 4 passes through the corresponding movable channel, an adjustment component for adjusting the tightness of the fixing belt 3 is provided. In this embodiment, the base 1 and the operating table 2 are fixed by hexagon socket bolts. When using this device, the anesthetized rat is placed on its back on the operating table 2, and then the rat's limbs are placed under the fixing belt 3. The material of the fixing belt 3 can be made of silicone rubber, nylon webbing, or other materials with certain elasticity and good wrapping performance. The experimenter fine-tunes the tightness of the fixing belt 3 according to the strength of the rat's limbs to avoid the fixing belt 3 being too tight or too loose affecting the experiment or causing harm to the rat. After the rat is fixed, the jaw assembly is adjusted so that the jaw The bone component opens the rat's mouth. Specifically, the jaw component opens the rat's upper and lower jaws and the buccal mucosa, thereby obtaining a continuous, stable, and widely exposed effective working field of view, which is convenient for subsequent various operations on the rat's periodontium. When this tool is used to fix rats of different sizes and strengths, the fixing belt 3 can be fine-tuned by adjusting the component, thereby ensuring that the rat's limbs are fixed while not binding the rat's limbs too tightly to affect the blood circulation of the rat's limbs. This complies with ethical standards and helps ensure the accuracy and reliability of experimental data.

[0021] like Figure 1-3 As shown, the adjustment assembly further includes a rotating column 5, one end of which is connected to the movable channel. The rotating column 5 has a through hole for the fixed rope 4 to pass through. A plurality of spring clips 6 are spaced apart at one end of the rotating column 5 toward the movable channel. The end of the movable channel near the rotating column 5 has a tapered hole that drives the plurality of spring clips 6 toward the axis of the rotating column 5. The end of the fixed rope 4 that extends from the movable channel is inserted into the through hole of the rotating column 5, and the rotating column 5 is then engaged with the movable channel. The tension of the fixed strap 3 on the operating table 2 is adjusted by pulling the length of the fixed rope 4 extending from the through hole. After the adjustment is in place, the rotating column 5 is moved into the movable channel. Due to the restraining effect of the tapered hole, the spring clips 6 on the rotating column 5 move toward each other, thereby clamping the fixed rope 4. The rotating column 5 is also engaged with the movable channel, thereby completing the adjustment of the tension of the fixed strap 3. Preferably, the connection between the rotating column 5 and the movable channel can be a threaded connection.

[0022] like Figure 1 and 4 As shown, the jaw assembly further includes: two first bellows 7, each of which is mounted on the top of the operating table 2 via a connecting column. Two elastic rods 8 are spaced apart on the end of each first bellows 7 away from the operating table 2. The elastic rods 8 are made of an elastic material, such as carbon steel. When the upper and lower jaws of a rat are opened, the two first bellows 7 are adjusted to move to the sides of the rat's mouth. Then, the two elastic rods 8 on the two first bellows 7 are respectively placed on both sides of the rat's mouth, thereby supporting the entire rat's mouth and preventing it from closing, facilitating subsequent operations such as surgery and imaging.

[0023] like Figure 5 As shown, a mounting post 9 is further provided at one end of the first bellows 7 away from the operating table 2. A threaded groove is formed at one end of the mounting post 9, and a first threaded post 10 is screwed onto the threaded groove. Two elastic rods 8 are respectively provided on the first threaded post 10 and at the end of the mounting post 9 away from the first threaded post 10. Because the oral cavity sizes of different rats vary, in order to minimize injury to the rats, the experimenter can adjust the spacing between the two elastic rods 8 on the same first bellows 7 by rotating the first threaded post 10 so that the first threaded post 10 is screwed into or out of the threaded groove, thereby adapting to the different oral sizes of rats.

[0024] like Figure 1 and 4 As shown, further, each elastic rod 8 is provided with a silicone sleeve 11 at one end away from the first corrugated tube 7. The silicone sleeve 11 can further protect the rat's oral cavity and reduce the possibility of mechanical damage.

[0025] like Figure 1 and 5 As shown, the apparatus further includes: a second bellows 12, one end of which is disposed on the top of the base 1, and a U-shaped clip 13 is disposed on the end of the second bellows 12 away from the base 1. The U-shaped clip 13 is made of an elastic material to accommodate airways of different diameters. The airway is fixed to the connection with the anesthesia mask, which facilitates the anesthesia operation of the rat during surgery. The connection through the second bellows 12 allows the angle and position of the U-shaped clip 13 to be easily adjusted to prevent it from interfering with the surgical operation and facilitate anesthesia operation by a single person.

[0026] like Figure 1 and 5As shown, the embodiment further includes: a mounting block 14, one end of which is fixedly connected to the second bellows 12, and the other end of which is fixedly provided with a second threaded column 15. The top of the base 1 is provided with at least one screw hole that cooperates with the second threaded column 15. In this embodiment, the top of the base 1 is provided with two screw holes, and the second threaded column 15 is screwed into the screw holes to achieve a detachable connection with the second bellows 12. The square mounting block 14 allows the experimenter to easily rotate it to achieve the removal and installation of the second bellows 12, and the experimenter can select the installation position of the second bellows 12 according to the operation requirements.

[0027] like Figure 1 As shown, further, a liquid collecting tank 16 is provided on the top of the operating table 2. The liquid collecting tank 16 collects liquid (such as physiological saline) produced during the operation and collects secretions or excrement produced by the rat, keeps the working environment clean, and reduces problems such as pollution caused by liquid diffusion.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
