Description

Technical Field

[0001] The utility model relates to the technical field of rat experimental equipment, in particular to a rat oral cavity fixing and photographing device. Background Art

[0002] In the process of conducting oral research on rats, due to the small size, diverse body shapes, strong mobility, and small oral space of rodents, traditional rat oral fixation devices cannot adapt to the sizes of rats of different sizes, the limb restraint length is limited, and it takes too long for researchers to fix the next rat after completing the experimental operation, which is inconvenient. During the maxillofacial fixation process, traditional fixation devices can easily cause secondary damage to the rat's mouth. Rats under anesthesia may wake up temporarily, and researchers need to release them first, which makes it impossible to perform secondary anesthesia in time, causing stress and injury to the experimental animals. In addition, traditional fixation methods often require the collaboration of multiple people. Not only is the operation complicated and confusing, but it is also more likely to cause stress and injury to rats, affecting the accuracy and reliability of the experimental results.

[0003] The existing patent (Announcement No.: CN210408667U) discloses a rat retinal observation experimental fixation device, which relates to the technical field of experimental devices. It includes a base, a support seat with one end hinged to the base and the other end hinged to a support rod, and a random stop support with two ends respectively hinged to the base and the support rod; a universal ball bracket is provided at the upper end of the support rod, and an observation platform is fixed on the universal ball bracket; the observation platform is provided with a rat fixing part for positioning and fixing the rat. In the process of implementing this solution, the inventor found that the following problems in the prior art have not been well solved: the device uses an abdominal corset to fix the rat, and the rat itself can still move, and the restraint effect is limited; if the rat wakes up during the implementation process, the anesthetic operation is more troublesome.
