Description
Technical field
This utility model relates to technical field of medical treatment mechanical, is specially a kind of adjustable oral cavity gag.
Background technology
Patient is when carrying out operation on oral cavity, for exposing surgical field of view, gag need be used to make the oral cavity of patient keep open configuration, and the folding size of existing gag is fixing, different patients cannot be adapted to use, and the passive type gag that the gag used clinically mostly is one-sided or bilateral uses, its action principle is that wedge is done to make lower jaw decline opening, rely on patient or doctor to wedge gag and make patient dehisce a fixing position, after patient dehisces, lower jaw can not do motion of remaining silent again, constantly to increase chock in using or increase wedging strength, operation versus busy, after patient dehisces, lower jaw can not do motion of remaining silent again, masticatory muscles can not be trained effectively, masticatory muscles functional rehabilitation is not good, the mouth opening formed not easily maintains.
Utility model content
The purpose of this utility model is to provide a kind of adjustable oral cavity gag, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme: a kind of adjustable oral cavity gag, comprise maxillary plate and mandibular plate, described maxillary plate and mandibular plate rearward end are welded with shell fragment, lowering or hoisting gear is provided with between described maxillary plate and mandibular plate, described lowering or hoisting gear comprises the first elevating lever, second elevating lever and cutting ferrule, described second elevating lever top is provided with limited block, and limited block is arranged in cutting ferrule inner chamber, convex body is provided with bottom described cutting ferrule, be connected with mandibular plate bottom described second elevating lever, cutting ferrule is run through in described first elevating lever one end, and extend in the second elevating lever inner chamber, the described first elevating lever other end is connected with maxillary plate.
Preferably, described maxillary plate and mandibular plate surface are equipped with soft rubber pad.
Preferably, described second elevating lever shape is T-shaped.
Compared with prior art, the beneficial effects of the utility model are: this oral cavity mouth gag is by retracting cylinder and shell fragment, and upper mandibular plate oneself can be pinched and close by doctor or patient, puts between upper and lower facies occlusalis dentis after mandibular plate is close to, spring after decontroling in retracting cylinder, resilience can provide lasting opening force, and volume is little, wears conveniently, simple to operate, use comfortable, when wearing, lower jaw can do motion of remaining silent, and masticatory muscles function can effectively be taken exercise.
