Assembly relation

The oral cavity supporter of Adjustable device hyoplastron, including oral cavity supporter 2, Adjustable device hyoplastron 1, regular length keep off hyoplastron 3, mouth The lower section of the oral cavity supporter top half 5 of chamber eyelid retractor 2 have dextrorotation wire rod thread hole, oral cavity supporter lower half portion 9 it is upper There is left-handed wire rod thread hole in side, and the intermediate of Bidirectional-screw 8 connects height adjustment knob 4, Bidirectional-screw 8 and height adjustment knob 4 It is integral structure, 8 two end of Bidirectional-screw is respectively left or right rotation screw rod, and Bidirectional-screw 8 screws in oral cavity supporter top half 5 Right-handed thread hole, 9 left handed threaded hole of oral cavity supporter lower half portion.

There is Adjustable device hyoplastron fixing screwed hole 10 in oral cavity supporter lower half portion 9, and Adjustable device hyoplastron 1 is fixed by keeping off hyoplastron 12 spiral of screw rod screws in Adjustable device hyoplastron fixing screwed hole 10 and connects oral cavity supporter lower half portion 9, and the Adjustable device hyoplastron 1 is Nested type retractable structure, inside installation V-arrangement Location resilient piece 15, gear hyoplastron set 14 are the outer protection cage plates of Adjustable device hyoplastron 1, It is opened on gear hyoplastron set 14 there are three length-adjustment holes 13, the depth that gear hyoplastron body 17 is inserted into gear hyoplastron set 14 is more than three length tune The position of knothole 13, hoodle when gear hyoplastron is flexible on V-arrangement Location resilient piece 15 are fallen into gear hyoplastron length-adjustment holes 13, fixed gear 17 extension elongation of hyoplastron body.

Locating rod 7 is cylinder, and point bilateral symmetry two, the locating rod 7 is fixedly connected in the oral cavity supporter upper half Divide 5 lower section, the locating rod 7 is inserted into the locating rod circular trough 11 of 9 top of oral cavity supporter lower half portion, for guaranteeing mouth The relative position of chamber eyelid retractor top half 5 and oral cavity supporter lower half portion 9 remains unchanged.

Regular length keeps off hyoplastron 3 and connects oral cavity supporter 2 by wedge, and the gear hyoplastron wedge shape that regular length keeps off hyoplastron 3 is solid 16 interference of fixed column wedging regular length gear hyoplastron fixation hole 6 is fastened on oral cavity supporter 2.

The outer end connection safety that safety pulls line 18 pulls ring 19, and the inner end for pullling line 18 safely is set shape, pulls safely The interior end cap of line 18 is in locating rod 7.

The design principle of the utility model is as follows:

For supporting oral cavity body in I-shaped, the above and below of supporting oral cavity body is all recessed arc-shaped, described arcwall face Structure is conducive to the positioning and stabilization when supporting oral cavity body and dental articulation, oral cavity supporter top half 5 and supporting oral cavity Device lower half portion 9 is connected by Bidirectional-screw 8, and Bidirectional-screw 8 and height adjustment knob 4 are integral structure, 8 two end of Bidirectional-screw Respectively left or right rotation screw rod drives Bidirectional-screw rotation by rotation height adjusting knob 4, adjusts oral cavity supporter upper half The relative distance of part 5 and oral cavity supporter lower half portion 9 realizes the work that bearing height is adjusted according to the size in patient oral cavity With, patient both can bite oral cavity supporter in oral cavity side, can also in the oral cavity between with front tooth bite oral cavity supporter, sting Close part be it is recessed arc-shaped, when making to sting tight stress more concentrates, position with it is stable, play the work in assistance patient support oral cavity With.

The locating rod that is fixedly connected below oral cavity supporter top half 57, locating rod 7 are symmetrical two, and locating rod 7 can It is slided in locating rod circular trough 11 above oral cavity supporter lower half portion 9, for guaranteeing 5 He of oral cavity supporter top half The relative position of oral cavity supporter lower half portion 9 remains unchanged.

Adjustable device hyoplastron 1 is nested type retractable structure, inside installation V-arrangement Location resilient piece 15, the gear insertion gear of hyoplastron body 17 The depth of hyoplastron set 14 is more than the position of three length-adjustment holes 13, bullet when gear hyoplastron body 17 stretches on V-arrangement Location resilient piece 15 Pearl falls into gear hyoplastron length-adjustment holes 13, the extension elongation of fixed gear hyoplastron body 17, to be directed to the size in patient oral cavity not One and adjust gear hyoplastron body 17 length.

Patient in the oral cavity between when biting oral cavity supporter with front tooth, oral cavity supporter 2 and regular length gear hyoplastron 3 connect It connects, does not need to install Adjustable device hyoplastron 1 additional, since oral cavity supporter is engaged by intermediate teeth, regular length baffle can be blocked Tongue, the tongue movements of children just do not influence the treatment work to avris tooth；The gear tongue at 3 back side of hyoplastron is kept off by regular length Plate wedge shape fixed column 16 is connected and fixed with regular length gear 6 interference of hyoplastron fixation hole, and the interference connection is weak interference connection, both It can play the role of being fixedly connected, and can easy disassembly.

When oral cavity supporter is bitten in oral cavity side, oral cavity supporter uses patient in avris, oral cavity supporter and adjustable Gear hyoplastron is applied in combination, and passes through longitudinally varying and Adjustable device hyoplastron length the cross directional variations of oral cavity supporter height, Ke Yishi Close all ages and classes size, different oral cavity size children use.

A kind of oral cavity supporter of Adjustable device hyoplastron, not only the height of oral cavity supporter and the length of gear hyoplastron can bases The actual conditions of patient are adjusted, and can assist patient support oral cavity, effectively reduction of patient can open mouth because of long-time Fatigue caused by chamber, avoids patient due to pain or fatigue and there is a situation where lower jaws and tongue wobble effects to treat；Meanwhile Better operating space and the visual field can be provided for medical worker, greatly facilitate the progress for the treatment of work.

Safety pulls ring 19 and is fixed on foreign object or with pulling, plays the role of safeguard protection, in case support body slides into In oral cavity or fall.

The above is the utility model specific embodiment and the technical principle used, if according to the structure of the utility model Want done change, the spirit that the function generated is still covered without departing from specification and attached drawing, in the utility model Within the protection scope of patent.
