Description

Rat oral cavity experiment mouth gag

Technical Field

The utility model relates to a rat experiment technical field especially relates to a rat oral cavity experiment mouth gag.

Background

Animal experiments refer to scientific research conducted in laboratories using animals in order to gain new knowledge about biology, medicine, etc., or to solve specific problems. Animal experiments (including development of animal disease models) can be used for exploring human life, controlling human diseases and aging, and prolonging human life. Therefore, the importance of experimental animal science is becoming more and more recognized. The experimental animals are of various types, and the common experimental animals comprise dogs, rabbits, rats and the like, wherein the rats are frequently used as experimental animals for oral experiments.

Common rat oral cavity experimental applications include rat experimental periodontitis animal models, experimental rat oral ulcer healing experimental models, rat experimental oral cavity precancerous lesion models, and the like. Rat oral cavity experiment needs rat to accomplish under the open mode, but rat oral cavity volume is little, and when present most rat oral cavity experimental model accomplished the operation, all use apparatus such as a plurality of needle holders or tweezers to open the rat oral cavity, though the experiment can be accomplished in the operation like this, its operation is comparatively complicated, has increased the experiment degree of difficulty, has reduced the experiment success rate.

Therefore, there is a need to provide a new mouth gag for rat oral cavity experiment to solve the above technical problems.

Disclosure of Invention

The utility model provides a technical problem provide a preparation is convenient, and the operation is comparatively simple, places the opening work that can accomplish the whole experiment of rat in the rat mouth with this mouth gag before only needing the experiment to need not to carry out the rat oral cavity experiment mouth gag of other operations in the experimentation.

In order to solve the technical problem, the utility model provides a rat oral cavity experiment mouth gag includes: a female-type rod; one ends of the two first connecting rods are fixedly arranged at two ends of the concave rod respectively; one ends of the two large coiling bending springs are fixedly connected with the other ends of the two first connecting rods respectively; one end of each of the two second connecting rods is fixedly connected with the other end of each of the two coiled large open curved springs; and two ends of the cross rod are respectively fixedly connected with the other ends of the two second connecting rods.

Preferably, the concave rod, the first link, the looped open large bent spring, the second link and the cross rod are integrally provided.

Preferably, the first connecting rod and the second connecting rod are both L-shaped rods, and the included angle of the L-shaped rods is smaller than 90 °.

Preferably, the connection parts between the concave rod, the first connecting rod, the looped large bent spring, the second connecting rod and the cross rod are all provided with radians.

Compared with the prior art, the utility model provides a rat oral cavity experiment mouth gag has following beneficial effect:

the utility model provides a rat oral cavity experiment mouth gag, the preparation is convenient, and the operation is comparatively simple, places the opening work that can accomplish the whole experiment of rat in the rat mouth with this mouth gag before only needing the experiment to need not to carry out other operations in the experimentation.

FIG. 2 is a schematic top view of the structure of FIG. 1;

fig. 3 is a side view of the structure shown in fig. 1.

Reference numbers in the figures: 1. the device comprises a concave rod, 2, a first connecting rod, 3, a large coiling spring with a coil, 4, a second connecting rod, 5 and a cross rod.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and embodiments.

Please refer to fig. 1, fig. 2 and fig. 3 in combination, wherein fig. 1 is a schematic perspective view of a preferred embodiment of a mouth gag for rat oral cavity experiments according to the present invention; FIG. 2 is a schematic top view of the structure of FIG. 1; fig. 3 is a side view of the structure shown in fig. 1. Rat oral cavity experiment mouth gag includes: a female rod 1; one ends of the two first connecting rods 2 are fixedly arranged at two ends of the concave rod 1 respectively; the two large coiling springs 3 are provided with rings, and one ends of the two large coiling springs 3 are respectively fixedly connected with the other ends of the two first connecting rods 2; one end of each of the two second connecting rods 4 is fixedly connected with the other end of each of the two coiled open large curved springs 3; and two ends of the cross rod 5 are respectively fixedly connected with the other ends of the two second connecting rods 4.

The concave rod 1, the first connecting rod 2, the large coil spring 3, the second connecting rod 4 and the cross rod 5 are integrally arranged, the mouth gag can be bent into a shape shown in figure 1 by adopting a stainless steel wire, and then the head and the tail of the stainless steel wire are welded to complete the manufacture of the mouth gag.

First connecting rod 2 with second connecting rod 4 is L type pole, just the contained angle of L type pole is less than 90, sets up to be less than 90 through the contained angle with L type pole and can conveniently put into rat mouth with this mouth gag, simultaneously through the number of degrees and the coefficient of torsional spring 3 of the contained angle of control L type pole, can realize rat open-ended not equidimension.

The connecting parts among the concave rod 1, the first connecting rod 2, the coiled large open curved spring 3, the second connecting rod 4 and the cross rod 5 are all provided with radians.

The utility model provides a rat oral cavity experiment mouth gag's theory of operation as follows:

during the use, put into the mouth of mouse with concave type pole 1, and make the recess of concave type pole 1 support the tooth on the rat palate, this process lets two head rods 2, two area circle open big bent spring 3 and two second connecting rods 4 be located the both sides of rat cheek respectively, then promote horizontal pole 5, until horizontal pole 5 gets into in the rat mouth, and make horizontal pole 5 support on the tooth of rat chin, then loosen horizontal pole 5, at head rod 2 this moment, area circle open big bent spring 3 and second connecting rod 4's effect down and ascending power is applyed respectively with the lower tooth and the upper teeth of rat to make horizontal pole 5 and concave type pole 1 respectively, thereby can separate the upper tooth and the lower tooth of rat, thereby can realize the opening to the rat.

the utility model provides a rat oral cavity experiment mouth gag, the preparation is convenient, and the operation is comparatively simple, places the opening work that can accomplish the whole experiment of rat with this mouth gag in the rat mouth before only needing to test to need not to carry out other operations in the experimentation.
