SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the utility model is as follows: overcomes the defects in the prior art, and provides the oral cavity mouth gag which has the function of uvula retraction, can fully expose the visual field of oral cavity operation and is convenient and quick to operate.

The oral cavity mouth gag comprises a drawing frame, wherein a uvula pull hook assembly is arranged on an upper cross beam of the drawing frame; the uvula drag hook assembly comprises a uvula drag hook and a base, wherein an assembly groove and a drag hook groove are formed in the base, the base is installed on the upper cross beam through the assembly groove, the uvula drag hook is installed in the drag hook groove and can move back and forth in the drag hook groove and can be locked through a positioning mechanism.

Preferably, the spring plate is arranged on the groove wall at one side or two sides of the assembling groove, and the spring plate is arranged on the base through bent sections at two ends of the spring plate.

Preferably, the positioning mechanism comprises a plurality of sawtooth type limiting teeth and a clamping button which are arranged on the uvula draw hook, the clamping button is arranged on the base, a through hole which is communicated with the drawing groove is formed in the base corresponding to the clamping button, and the head of the clamping button penetrates through the through hole to be clamped on the sawtooth type limiting teeth of the uvula draw hook so as to realize the positioning of the uvula draw hook.

Preferably, a supporting rod is installed on the base, the clamping button is movably connected with the supporting rod through a pin shaft, and a spring is installed at the tail of the clamping button. Further preferably, a spring groove is provided on the base corresponding to the spring.

Preferably, the tail part of the uvula draw hook is provided with a draw hook push-pull button. The pull-push button of the draw hook and the tail of the uvula draw hook can form a certain included angle.

Compared with the prior art, the utility model has the beneficial effects that:

the mouth cavity mouth gag is additionally provided with the uvula pulling assembly, is used for pulling the uvula in the mouth cavity of a patient and exposing the operation visual field in the mouth cavity in the process of mouth cavity operation, is convenient and quick to pull, and is stable in pulling operation because the uvula pulling hook is displaced along the pulling groove in the pulling process.
