Problems solved by technology

However, in the actual operation process, due to the limp limbs of the rats after anesthesia and the small mouth of the rats, how to effectively fix the rats and open the rat mouths has become a major problem for the operators.
[0003] Under the current conditions, most experimenters simply fix the rats on the experimental console after anesthesia. One person is responsible for fixing the rat’s head and pulling the rat’s upper and lower jaws to open the mouth, and the other person performs the oral cavity experiment operation, which usually requires the cooperation of 2 people. Done, time consuming
In addition, due to the unsatisfactory control of the depth and time of anesthesia, sudden movements of rats often occur during the operation, which seriously affects the experimental operation. So far, there is no ideal solution

Embodiment 1

[0032] Embodiment 1. In this embodiment, the top end of the first longitudinal beam 2 and the top end 10 of the second longitudinal beam are both provided with convex parts, and the cross beam is provided with grooves at corresponding positions. The top of the stringer 2 and the top 10 of the second stringer, such as figure 2 Shown; At the same time, the two sides of the platform body 1 are provided with mounting grooves 12, and the sides of the first longitudinal beam 2 are provided with lateral protrusions, and the lateral protrusions 11 of the first longitudinal beam are installed in the mounting grooves 12, and the second longitudinal beams The side of the side is provided with a side protrusion, and the side protrusion of the second longitudinal beam is installed in the installation groove.

[0033] In order to allow the rats’ limbs to be pulled apart evenly in the experiment, the distance between the first fixing component and the support frame is 2 / 3-3 / 4 of the distanc...

Embodiment 2

[0034] Example 2, such as Figure 1-2 As shown, the upper tooth fixing part 8 in this embodiment is a ring; the lower tooth fixing part 9 is a ring. In order to facilitate the oral cavity fixing component to fit the rat's teeth, the ring is made of plastic material, mainly using plastic Toughness and tensile properties of the material. The upper tooth fixing part 8 is a ring. The lower tooth fixing part 9 is a thread, and the thread is connected to the crossbeam by a round needle with a thread during use. Specifically, one end of the thread passes through 1 / 3 of the rat tongue and is clamped together with the other end of the thread on thin wires attached to beams. When in use, the round needle passes through 1 / 3 of the tongue of the rat, and at the same time pulls the mandible backward, and fixes it on the thin wire through the needle holder. Further, the crossbeam is provided with a mounting ring, and the thin wire is connected to the on the ring.

Embodiment 3

[0035] Example 3, such as image 3As shown, the upper tooth fixing part 8 includes a second front protrusion and a second rear protrusion located on both sides of the second front protrusion, and the second rear protrusion is connected to the table body 1; the lower tooth fixing part 9 includes a first protruding part 91 and a first protruding part 92 respectively arranged on both sides of the first protruding part 91, the first protruding part 92 is connected with the crossbeam, and the first protruding part 91 faces the direction of the mouth of the rat It is located at the extension end; when in use, the extension end forms a space with the lower jaw of the rat, the tongue of the rat is limited in this space, and the first protruding part 91 fixes the upper teeth of the rat. Preferably, the upper tooth fixing member 8 is connected to the table body 1 by a thin wire; the end of the table body 1 in the length direction is provided with a screw 7, and the thin wire is tied to ...

Abstract

The invention belongs to the technical field of medical experimental animal equipment and particularly relates to a rat oral cavity experiment operating platform and a use method thereof. The rat oralcavity experiment operating platform comprises a platform body, a support frame, a first fixing component, a second fixing component and an oral cavity fixing part, wherein the support frame comprises a cross beam as well as a first longitudinal beam and a second longitudinal beam which are used for supporting the cross beam; the cross beam is supported by the top end of the first longitudinal beam and the top end of the second longitudinal beam together; the first fixing component comprises a first connecting column and a second connecting column; the second fixing component comprises a third connecting column and a fourth connecting column; the oral cavity fixing component comprises an upper tooth fixing part and a lower tooth fixing part; the upper tooth fixing part is connected with one end in the length direction of the platform body and is near to the first fixing component, the distance between the upper tooth fixing part and one end in the length direction of the platform bodyis adjustable; the lower tooth fixing part is connected with the cross beam, and the distance between the lower tooth fixing part and the cross beam is adjustable. The rat oral cavity experiment operating platform can effectively open the oral cavity of a rat and is simple in installation and convenient in operation.

Description

technical field [0001] The invention belongs to the technical field of medical experimental animal equipment, and in particular relates to a rat oral cavity experimental operating platform and a using method thereof. Background technique [0002] Rats are one of the commonly used experimental animals in the field of medical animal experiments. They are often used to replicate animal models such as periodontitis, apical periodontitis, dental fluorosis, and Candida albicans infection in oral medicine experiments. However, in the actual operation process, due to the limp limbs of the rats after anesthesia and the small mouth of the rats, how to effectively fix the rats and open the rat mouths has become a major problem for the operators. [0003] Under the current conditions, most experimenters simply fix the rats on the experimental console after anesthesia. One person is responsible for fixing the rat’s head and pulling the rat’s upper and lower jaws to open the mouth, and th...
