Description of the embodiments
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1-2, the present utility model provides a technical solution: the oral cavity mouth gag comprises a support frame 1 and L-shaped support arms 2, wherein the middle part of the support frame 1 is connected with a screw rod 3 through threads, one end of the screw rod 3 is connected with a handle 4, two sides of the support frame 1 are hinged with short arms of the two L-shaped support arms 2 through rotating shafts, and the two L-shaped support arms 2 are symmetrically arranged by taking the axis of the screw rod 3 as the center;
the long arm of the L-shaped supporting arm 2 is connected with a biting block 5 through a hinge limit at one end far away from the supporting arm 1, and an arc-shaped end 51 is formed at one end of the biting block 5 far away from the L-shaped supporting arm 2;
the L-shaped supporting arm 2 is also provided with a saliva sucking mechanism.
In a normal state, the screw 3 is positioned in the threaded hole, one end of the screw 3, which is close to the support frame 1, is positioned in the threaded hole, the screw 3 does not exceed the support frame 1, the rotation friction coefficient between the support frame 1 and the L-shaped support arm 2 and between the engagement block 5 and the L-shaped support arm 2 is large, the screw cannot rotate at will, and the normal state is kept vertical; the length of the occlusion block 5 is larger than the depth of the mouth of a person, and the width of the occlusion block 5 is smaller than the width of the mouth of the person.
When in use, the occlusion block 5 needs to be plugged into the mouth of a patient by hand, because the rotation friction coefficient between the occlusion block 5 and the L-shaped support arm 2 is larger, the occlusion block 5 and the L-shaped support arm 2 can be kept fixed when in use, the occlusion block 5 can not rotate, after the occlusion block 5 is plugged into the mouth of the patient, the screw 3 is driven to move towards the direction of the L-shaped support arm 2 by rotating the screw 3 through the handle 4, the L-shaped support arm 2 rotates under the pushing of the screw rod 3, the mouth of a patient is driven to open by a certain angle, the L-shaped support arm 2 is moved laterally to enable the position of the L-shaped support arm 2 to deviate, at the moment, the hinge between the L-shaped support arm 2 and the occlusion block 5 is folded, the occlusion block 5 also rotates due to the friction force between the upper side and the lower side of the occlusion block and the tooth contact of the patient, and finally the L-shaped support arm 2 and the front section of the L-shaped support arm deviate to the side wall of the oral cavity, so that the operation space is enlarged
Referring to fig. 2, in order to avoid the deviation between the two engaging blocks 5 when the L-shaped support arm 2 is not opened, a limiting block 55 and a fixing groove 54 corresponding to the limiting block 55 are respectively provided on the abutting surface between the two engaging blocks 5. The two engagement blocks 5 are fixed through the fixing grooves 54 and the corresponding limiting blocks 55, so that the two engagement blocks can be kept at the same angle.
