Description

Oral cavity experimental animal mouth gag
Technical field
The utility model is related to a kind of opener, more particularly to a kind of oral cavity experimental animal mouth gag, belongs to medical Mechanical field.
Background technology
(such as periodontal disease model, Orthodontic movement model) is usually required dynamic in mouth disease research zoopery Thing is operated in oral cavity, and the small operation difficulty in the visual field is big, it is therefore desirable to which special opener struts and fixes animal oral cavity.
Authorization Notice No. discloses a kind of rat oral cavity for the U of CN 202875527 Chinese utility model patent and laterally opened Mouthpart.The product is clamp, and in actual use with more defect, such as build is larger, lays difficult and easy damaged dynamic Thing mucous membrane, tooth and mucous membrane can not completely expose, and operable space is small, be unfavorable for experimental implementation and the interior experiment feelings of display port of taking pictures It is difficult to adjust riding position in condition, surgical procedure, it is expensive and be difficult to sterilize, it is necessary to stranger's auxiliary operation etc..Publication number A kind of lip mouth stripper for pika experiment animal is disclosed for CN 101396306A Chinese patent.The product is although can support The upper lower jaw of pika class experimental animal is opened, but can not be constrained to mucous membrane, upper inferior border of mandible, therefore can not effectively expose cavity interior Structure.And after the product mounting, riding position fine setting can not be easily carried out in experimentation.
Utility model content
There is provided in a kind of oral cavity experimental animal experimentation aiming at the deficiencies in the prior art for the purpose of this utility model The opener used.Product is easy to use, can effectively expose animal oral cavity structure, low processing cost.
To achieve the above object, technical scheme is as follows:
Oral cavity experimental animal mouth gag, including main component;It is characterized in that:The main component is frame structure, including butterfly It is shape plane, preceding prominent, it is described before prominent be located at butterfly shaped plane both sides respectively and made an angle alpha with butterfly shaped plane.
Above-mentioned opener is used in the animal medicine experiment of oral cavity, for strutting and fixing animal oral cavity.Product in use, Butterfly shaped plane is used to strut upper and lower jaw, prevents occlusion.Dash forward and fix respectively at the both sides buccal mucosa of animal before left and right, play and strut The effect of both sides buccal mucosa.
Under optimum condition, above-mentioned opener can do following optimization design, so as to real more suitable for oral cavity animal medicine The oral cavity structure of the rodents such as mouse, the rabbit commonly used in testing.
Above-mentioned opener, the upper and lower middle part of butterfly shaped plane bends to upper recess, lower concave part, upper recess to planar central respectively Both sides are left and right upper convex portions, and lower concave part both sides are convex portions under left and right;Dash forward and be located between left side upper convex portion and lower convex portion before left side, it is right Dash forward and be located between right side upper convex portion and lower convex portion before side.In use, upper recess is fixed on animal infradentale tongue side, left and right The inferior border of mandible of the stable animal of convex portion auxiliary, so as to complete strutting and fixed for animal lower jaw.Lower concave part is fixed on animal Convex portion auxiliary holds the maxilla lower edge of animal under maxillary central incisors tongue side, left and right, so as to realize strutting and solid for the animal upper jaw It is fixed.
Further, upper recess curvature is more than lower concave part curvature, and upper convex portion curvature is more than lower convex portion curvature.Ordinary circumstance Under, main component is bilateral symmetry.Each bending jog after optimization design ensures that the oral cavity of animal is strutted completely, and And stably it is difficult activity so that the experimental implementation visual field becomes apparent from stabilization, and a people can complete the operation technique of animal.
