Problems solved by technology

However, the equipment used in the traditional opening method is too simple, which will bring a lot of inconvenience to the experimenters
On the one hand, the rat's mouth space is relatively small, and the operating field of view and operating space are limited. During the implementation, the rat's head will move left and right, and the opening area will be large and small, which reduces the accuracy of the operation.
On the other hand, the opening device and the rat are not fixed in a suitable position, and need to be manually fixed by the experimenter, which increases the difficulty of the experimental operation

Embodiment 1

[0034] Such as figure 1 The rat mouth gag includes a base 1, a forward gag 2, a side gag 3 and a rat fixing plate 4;

[0035] The base 1 is a rectangular tank, and the left and right sides of the top surface of the base 1 are symmetrically provided with an opener base 5, and the upper and lower sides are also symmetrically provided with an opener base 5; the described opener base 5 is a cuboid, vertically It is arranged directly on the top surface of the base 1, with a rectangular through-hole I9 on the upper end, a U-shaped groove 6 in the middle, and a circular through-hole II8 on the side of the U-shaped groove 6, and the through-hole II8 runs through the U-shaped groove 6 the two sides of

[0036] The forward opener 2 includes a rack I12 and a gear I17, the gear I17 is arranged below the rack I12 and meshes with the rack I12, the middle part of the gear I17 is provided with a rotating shaft I20, and the end surface of the rotating shaft I20 is provided with a knob I18, O...

Embodiment 2

[0042] The difference between this embodiment and Embodiment 1 is that the side of the base 1 is provided with a through hole V21, which can save materials and increase the ventilation of the rat gag.

[0043] The working principle of this embodiment is the same as that of Embodiment 1.

Embodiment 3

[0045] The difference between this embodiment and Embodiment 2 is that the fixed rod 15 is cylindrical, and the fixed rod 15 is cylindrical so that the rat will not be injured during the process of stretching and fixing the front and rear teeth of the rat.

[0046] The working principle of this embodiment is the same as that of Embodiment 1.

Abstract

The invention discloses a rat mouth gag which comprises a base, a forward mouth gag, a lateral mouth gag and a rat fixing plate. The base is a rectangular groove body, the opener bases are symmetrically arranged on the left side and the right side of the top surface of the base, and the opener bases are also symmetrically arranged on the upper side and the lower side of the top surface of the base; the forward mouth opener and the lateral mouth opener are mounted on mouth opener bases on the upper side and the lower side of the base, one end of the forward mouth opener and one end of the lateral mouth opener penetrate through the through hole I, and the other end of the forward mouth opener and the other end of the lateral mouth opener are mounted in the through hole II through a rotating shaft I; the rat fixing plate is obliquely arranged in the middle of the base, the chest fixing belt and the leg fixing belt are arranged on the top face, the supporting rod is arranged on the bottom face, one end of the supporting rod is connected with the rat fixing plate, and the other end of the supporting rod is connected with the base. According to the rat mouth gag, on one hand, anterior teeth, posterior teeth, upper jaw and lower jaw of a rat can be opened in four directions at the same time, the opening distance in each direction can be independently adjusted, and on the other hand, the position of the rat and the positioning of the mouth gag can be achieved.

Description

technical field [0001] The invention belongs to the technical field of auxiliary equipment for animal medical experiments, and in particular relates to a rat mouth gag. Background technique [0002] At present, when conducting experiments in the oral cavity and maxillofacial region of rats, it is necessary to open and position the animal's oral cavity. The traditional opening method is to use simple fly ropes or self-made steel wire rings to open and fix the front and rear of rats. Posterior teeth or upper and lower jaws. However, the equipment used in the traditional opening method is too simple, which will bring a lot of inconvenience to experimental workers. On the one hand, the rat’s mouth space is relatively small, and the operating field of view and operating space are limited. During the implementation process, the rat’s head will move left and right, and the opening area will vary from time to time, which reduces the accuracy of the operation. On the other hand, th...
