Rodent mouth opening and oral surgery auxiliary device

Abstract

The invention discloses a rodent mouth opening and oral surgery auxiliary device. The device comprises an upper jaw frame and a lower jaw frame, left and right buccal mucosa support frames are connected between the upper and lower jaw frames, the upper and lower jaw frames and the two buccal mucosa support frames are connected through four first connecting pieces, and the distance between the upper and lower jaw frames and the distance between the two buccal mucosa support frames can be adjusted. By means of the mouth opening device, the interior structure of the oral cavity of a rodent can beeffectively exposed, and it is ensured that the operation on the oral cavity of the rodent is safely, efficiently and accurately carried out.

Description

technical field [0001] The invention relates to the field of opening devices, in particular to a rodent opening and an auxiliary device for oral surgery. Background technique [0002] In the study of oral diseases, rodents (such as mice, rats, rabbits, etc.) often need to operate in the animal's mouth, such as tooth extraction surgery, jaw bone implant surgery, periodontitis model construction, etc. In addition, such as irrigation Operations such as gastric lavage and sublingual surgery require a good field of vision to ensure the accuracy of the operation, so as not to cause experiment failure or damage the oral mucosa of the animal. Therefore, an opening device is often needed to keep the mouth open; at the same time, rodents Intraoral surgery in animals usually requires a long time to stretch the upper and lower jaws, which can easily cause discomfort in the temporomandibular joints of rodents and even temporomandibular joint diseases for a long time. Constricted, anesth...

[0002] In the study of oral diseases, rodents (such as mice, rats, rabbits, etc.) often need to operate in the animal's mouth, such as tooth extraction surgery, jaw bone implant surgery, periodontitis model construction, etc. In addition, such as irrigation Operations such as gastric lavage and sublingual surgery require a good field of vision to ensure the accuracy of the operation, so as not to cause experiment failure or damage the oral mucosa of the animal. Therefore, an opening device is often needed to keep the mouth open; at the same time, rodents Intraoral surgery in animals usually requires a long time to stretch the upper and lower jaws, which can easily cause discomfort in the temporomandibular joints of rodents and even temporomandibular joint diseases for a long time. Constricted, anesthetized rodents often aspirate blood into the lungs and die as a result of asphyxiation, so intraoral bleeding requires prompt and effective management

[0003] In the relevant patent documents disclosed at present, there is a clamp-type rat oral cavity lateral opening device (authorized announcement number is CN202875527U), but in actual use, due to its large size, it occupies more space in the oral cavity, which is not conducive to experimental operations. It is not easy to easily adjust the placement position according to the needs of the operating space during the process

Another lip-shaped opening device for pika experimental animals (the publication number is CN 101396306A), although it can stretch the upper and lower jaws of pika experimental animals, can not effectively support the soft tissues around the opening, so it cannot fully expose the internal structure of the oral cavity, such as Teeth, which is not conducive to the safe, efficient and accurate oral operation of rodents
