Abstract
The invention discloses a splitting active oral cavity mouth gag, which comprises an upper jaw plate, a lower jaw plate, upper and lower L-shaped force transfer rods, and an elastic restoring member, wherein the upper and lower L-shaped force transfer rods are fixedly connected in the middle of the upper jaw plate and the lower jaw plate, and the elastic restoring member is arranged between the upper and ; when in use, the upper jaw plate and the lower jaw plate are respectively worn to stabilize and are positioned on an upper dental arch maxillofacial and a lower dental arch maxillofacial; an elasticity rubber ring is hung on a small hook of the upper and lower force transfer rods; the amount of the rubber rings to be hung is adjusted according to the order of severity of the limited individual opening; and the shrinkage force that the rubber ring is extended achieves the function of continuously opening through the force transfer rods. The splitting active oral cavity mouth-opener has the advantages of small volume, convenient wearing and simple operation, can make a mouth-close movement of the mandible when worn, and can enable the function of the masticatory muscles to acquire effective practices; the size of the mouth opening force can be adjusted through increasing and decreasing the rubber ring; the engagement surface of the jaw plates are matched with the occlusal surface of patients and encircled by a buccal fin so as to acquire a stable fixed position. The splitting active oral cavity mouth gag can be used for computer assisting design of individual repairing body of the maxillofacial part.
Description
Technical field
The designed gag of the present invention is mainly used in training and helps the patient to dehisce, mainly be applicable to the expectant treatment or the postoperative Open mouth training of the temporomandibular joint damage that wound causes, also be applicable to the masticatory spasm that a variety of causes causes and the difficulty in opening mouth that causes, and can be used for the computer-aided design of the facial individuation dummy of jaw.
Background technology
The gag that uses clinically mostly is passive type gag one-sided or that bilateral uses now, its action principle is that wedge makes lower jaw decline opening, rely on the patient or the doctor wedges gag and the patient is dehisced a fixed position, patient's back lower jaw of dehiscing can not be done the motion of remaining silent again; The advantage of this kind gag is to make simply, and shortcoming is: will constantly increase chock in 1, using or increase wedging strength, operate numerous and diverse relatively; 2, lower jaw can not be done the motion of remaining silent again after the patient dehisced, and masticatory muscles can not be trained effectively, and the masticatory muscles functional rehabilitation is not good, and the mouth opening of formation is difficult for keeping.
Summary of the invention
At above-mentioned situation, the technical problem to be solved in the present invention is a kind of active oral cavity mouth gag of design.
Goal of the invention of the present invention realizes by implementing following technical proposals:
Splitting active oral cavity mouth gag, comprise maxillary plate, mandibular plate, be connected in maxillary plate middle part to dowel steel on the L type that the lower jaw direction is stretched out, be connected in the mandibular plate middle part to dowel steel under the L type that upper jaw direction is stretched out, be arranged on the L type elastic recovery part between the dowel steel under the dowel steel and L type, wherein the surface that contacts with the upper jaw of maxillary plate is a upper jaw contact surface, and the surface that mandibular plate contacts with lower jaw is the lower jaw contact surface.
As optimal way, described maxillary plate and mandibular plate have the shape of a hoof that conforms to the upperdental arch shape.
As optimal way, described elastic recovery part is the elastic force elastic ring.
As optimal way, the upper jaw contact surface of described maxillary plate is provided with the upper jaw indentation hole that cooperates with upper jaw denture, and the lower jaw contact surface of described mandibular plate is provided with the lower jaw indentation hole that cooperates with the lower jaw denture.
As optimal way, the outside of described maxillary plate upper jaw contact surface is provided with the upper jaw cheek flank of projection, and the described mandibular plate lower jaw contact surface outside is provided with the lower jaw cheek flank of projection.
As optimal way, the height of described upper jaw cheek flank, lower jaw cheek flank is 1mm.
As optimal way, the thickness of described maxillary plate and mandibular plate is 2.5mm-3.0mm.
As optimal way, on the described L type under dowel steel, the L type bar of dowel steel directly be 1.2mm.
As optimal way, described L shaped upward dowel steel and L shaped dowel steel down stretch out the partly long 2.5cm-3.0cm of body of rod level of upper and lower jaw plate, vertical partly long 2.5cm-3.0cm, and body of rod end has little hook.
As optimal way, described maxillary plate and mandibular plate are resin jaw plate.
During use, wear respectively earlier into going up mandibular plate, make it the stable upperdental arch jaw face that is located in, again in the little hook upper elasticity of dowel steel elastic ring up and down, can regulate according to the limited order of severity of individual opening and hang what of elastic ring, the contractility after elastic ring is stretched reaches the effect that continues opening by dowel steel.
Have with respect to existing its advantage of passive type gag: volume is little, wears conveniently, and simple to operate, lower jaw can be done the motion of remaining silent when wearing, and the masticatory muscles function can effectively be taken exercise; The big I of opening power is regulated by the increase and decrease elastic ring, and is easy to operate; Jaw plate occlusal surface and patient's tooth close the face coupling and have the cheek flank to hold, and therefore can obtain stable maintenance; Can be used for the computer-aided design of the facial individuation dummy of jaw.
