Description
Technical field
The present invention relates to a kind of oral cavity mouth gag, particularly relate to a kind of oral cavity mouth gag for clinical Open mouth training utilizing electronic installation to regulate size of dehiscing.
Background technology
Research shows, one of main physical signs of ankylosis of temporo-mandibular joint is limitation of mouth opening, after resetting, the quality of Open mouth training, will directly have influence on masticatory muscles function, and the exercise of application gag dehisces to be the effective method of one that temporomandibular joint Disease post-operative recovery function prevents from recurring.
But there is following defect in prior art: 1, be not practicable for different patient.Maxillary plate and mandibular plate shape in this patent, size are single, are fixedly connected with support body, not replaceable, and the difference of different patient's dentition categories, form, size is comparatively large, and gag can not mate with it one by one, namely cannot be applicable to different patient.2, patient be engaged uncomfortable.The groove that upper and lower jaw prelaminar part is divided is smooth, and the bite-block sheet that flexible material is made cannot be fixed; During gag work, easily there is relative displacement between tooth and upper and lower jaw plate, tooth discontinuity and pressure is excessive, easily cause patient to be engaged uncomfortable, even injury of teeth, cause pain.3, can not fine adjustment patient mouth opening keep mouth opening to immobilize.In this patent, user is by adjusting screw(rod) setting mouth opening maximum, but is manual operations due to it and does not have the numerical value of mouth opening size, is therefore difficult to the size accurately determining mouth opening; In use procedure, user presses for a long time and makes hand muscle fatigue, is difficult to keep fixing mouth opening, and tie down screw compresses support body and relies on frictional force to fix mouth opening, but its frictional force size can not meet fixing requirement completely, poor effect in practice.
In sum, aforementioned oral cavity mouth gag also can be further improved.
Summary of the invention
The present invention mainly fills up the blank of this art and apparatus now, and provide a kind of gag that electronic installation can be utilized in clinical Open mouth training to regulate mouth opening size, its concrete technical scheme is as follows:
Scalable is dehisced the oral cavity mouth gag of size, it is characterized in that: comprise ramus maxillaris fagging (1), ramus of mandible fagging (2), holder (3), lower retainer (4), dwang (5), connecting box (6), motor (7), handle (8); The front end of described holder (3) is connected with ramus maxillaris fagging (1) is dismountable, its rear end is connected with connecting box (6), the front end of lower retainer (4) and ramus of mandible fagging (2) are scalable to be dismountablely connected, and one end of its rear end and dwang (5) is connected through the hinge; The worm gear that cooperatively interacts (9) and worm screw (10) is provided with in described connecting box (6), the driven shaft (11) that dwang (5) is arranged by worm gear central shaft is connected with worm gear (9), dwang (5) is vertical with driven shaft (11), worm screw (10) with the motor of power (7) be provided be connected; Connecting box (6) below is provided with handle (8).
Described ramus maxillaris fagging (1) and ramus of mandible fagging (2) are outer arcuate relative to connecting box (6).
The upper surface of described ramus maxillaris fagging (1), the lower surface of ramus of mandible fagging (2) is respectively arranged with silicagel pad (12).
Described connecting box (6) is provided with control panel (13), control panel is provided with and controls the button of motor switch, adjustment and display and to dehisce the keyboard of size and time and display screen.
Described ramus of mandible fagging (2) is connected with on lower retainer (4) by slide rail pair (15), and the traffic direction of slide rail pair is the length direction of ramus of mandible fagging (2).

The power supply (16) of powering to motor and control panel is provided with in described connecting box (6).
Principle of dynamics of the present invention is: user, by control panel (13) feed opening degree and Open mouth training time, makes motor (7) turn over the fixing number of turns, makes gag can open fixing mouth opening under the control of control panel (13).The transmission rotating through worm screw (10) and worm gear (9) of motor (7) significantly changes gear ratio, makes motor (7) rotation one circle worm gear (9) rotational angle very little.Driven shaft (11) is connected with worm gear (9), transmit it and move to dwang (5), dwang (5) moves in a circle and drives down retainer (4) to rotate, under the effect of oral cavity external force, lower retainer (4) moves in a circle relative to the one end near dwang (5), ramus of mandible fagging (2) also under the effect of oral cavity external force along under the direction of retainer (4) move along a straight line and then simulate the motion of dehiscing in oral cavity, help user to carry out Open mouth training.Due to the self-lock mechanism of worm gear (10) and worm screw (9), motor still can keep fixing mouth opening after stopping power supply.Motor (7) reversion after Open mouth training, closed condition before use got back to by identical principle under shed device.
In the present invention, a kind of scalable is dehisced the oral cavity mouth gag of size, the effect of its ramus maxillaris fagging (1) and ramus of mandible fagging (2) is the pressure bearing the upper jaw and lower jaw in user oral cavity, assisting user carries out Open mouth training, is execution component of the present invention.
In the present invention, the effect of holder (3) is the position of fixing ramus maxillaris fagging (1), makes ramus maxillaris fagging (1) not produce displacement when being under pressure, and ensures stability and the intensity of gag itself.
The effect of its lower retainer (4) is the direction of motion of regulation ramus of mandible fagging, is moved in its direction along lower retainer, and the direction of motion that final acquisition is similar with mandibular movement direction, oral cavity, and ensure stability and the intensity of gag.
The effect of its dwang (5) is rotated under the driving of motor (7), provides assisting user to carry out the motive power of Open mouth training.
The effect of its connecting box (6) is connected as one holder (3) and lower retainer (4), and provide place for the placement of motor (7) and worm gear (9), worm screw (10) and driven shaft (11).
The effect of its motor (7) is to provide power source, for the motion of whole contrive equipment provides the foundation.
The effect of its handle (8) is hand-held for user, is convenient to user and uses.
The effect of its worm gear (9) and worm screw (10) makes the speed of dwang be reduced to controlled range by the change of gear ratio, improve opening degree precision and the opening degree relying on self-lock mechanism to keep opening is constant.
The effect of its driven shaft (11) be transmit worm gear (9) power to dwang (5), dwang (5) is rotated, and help user opens lower jaw.
The effect of its silicagel pad (12) cushions by the tooth of user, is unlikely to directly directly firmly to damage tooth to ramus maxillaris fagging (1) and ramus of mandible fagging (2).
The effect of its control panel (13) is the target mouth opening and the Open mouth training time that help user artificially to arrange gag, and controls motor and operate.
The effect of its T-shaped draw-in groove (14) is the connection of fixing silicagel pad (12) and ramus maxillaris fagging (1) or ramus of mandible fagging (2).
The effect of its slide rail pair (15) makes ramus of mandible fagging (2) can make relative rectilinear along the direction of lower retainer (4) to slide.
The present invention can change the size of mouth opening according to client need, mechanical mechanism also can be utilized after determining mouth opening by its maintenance, and also can replace with ramus of mandible fagging size and silicagel pad according to patient's condition, patient is hand-held convenient.
Tool of the present invention has the following advantages: 1. the automatic control and the maintenance that achieve oral cavity mouth opening, can ensure accuracy and the convenience of mouth opening.2. each assembly is easy to change, and can ensure that various types of Rehabilitation uses period, efficiency is high, and cost is low.3. be convenient to the hand-held use of patient.
