Description
Technical field
This utility model relates to a kind of medical auxiliary apparatus, specifically the special-purpose mouth-gag of temporomandibular joint.
Background technology
The patient who suffers from temporomandibular disorders, fracture and the damage of jaw facial muscle is through regular meeting's sensation limitation of mouth opening, pain.When carrying out the temporomandibular joint magnetic resonance examination, need the patient to dehisce as far as possible, keep the opening angle of temporomandibular joint.At present the patient is to dehisce by patient oneself when carrying out magnetic resonance examination, and without any adding equipment, because patient's pain degree is different, what cause dehiscing is in different size, and this makes checks not unified standard, causes data inaccurate easily.
Summary of the invention
Technical assignment of the present utility model is at above weak point, provide a kind of simple in structure, be easy to process, the special-purpose mouth-gag of temporomandibular joint of safe ready.
The technical scheme that its technical problem that solves this utility model adopts is: this mouth-gag comprises dens supporter and following dens supporter, last dens supporter and following dens supporter link together by rotating shaft, last dens supporter and rotating shaft are fixed together, following dens supporter links together by adapter sleeve and rotating shaft, but adapter sleeve phase countershaft rotates, have pin-and-hole on the adapter sleeve, bayonet lock cooperates with pin-and-hole.
Described going up on dens supporter and the following dens supporter all is provided with alveolus.
Described adapter sleeve is provided with 3-5 pin-and-hole.
During use, down dens supporter is adjusted to suitable angle, will descend between dens supporter and the rotating shaft with bayonet lock then locked, in the maintenance between dens supporter and the following dens supporter angle constant, fill in afterwards in patient's mouth and get final product.
The special-purpose mouth-gag of temporomandibular joint of the present utility model is compared with prior art, have reasonable in design, simple in structure, be easy to characteristics such as processing, volume are little, health easy to use, safe, can effectively help patient's posture that keeps dehiscing, guarantee to check and carry out smoothly.
