9 Claims.
My invention relates to devices for holding the mouth of a person open and is particularly adaptable for use by dentists while filling teeth, and while administering .gas and by surgeons while removing tonsils or performing any other operation in the oral cavity.
In the drawing, Figure 1 is a composite side elevation of the parts of my device separated and in an inoperative position.
Figure 2 is a top plan view thereof,
Figure 3 is a front elevation of the body portion of my device-showing its application in the mouth and also showing the plastic material as used therewith,
Figure 4 is a bottom plan view of the wedge shaped member of Figure 2,
Figure 5 is a vertical sectional view of my device in use,
Figure 6 is a sectional view taken on the line 66 of Figure 5, and
Figure 7 is a perspective w'ew of my complete device.
My jaw brace consists of a female or body member A and a male member or spacer B, the two members A and B co-acting together so as to form a complete device. Member A consists of two jaw engaging members I and Ia of substantially channel formation which are held in spaced relation from each other by means of a U-shaped leaf spring 2, which is attached at its ends as at 3 to the respective jaw engaging members I and lit. Spring 2 tends to maintain I and Iain a predetermined relation with their opposed faces converging toward the spring and to yieldingly resist any tendency of them to become separated. The convergence of the jaw engaging members corresponds approximately to the convergence of the jaws of the open mouth, so that the device may be easily inserted into the mouth and will cause a minimum of obstruction to access to the mouth by the operator. Members I and la. are provided with flanges 4 and 4a, respectively, flanges 4a being positioned in frictional contact with and within flanges 4. Both flanges 4 and 4a are of such vertical width and longitudinal length as to maintain contact with each other at all times and prevent relative lateral movement of the jaw engaging members and the spacer B.
Members I and Ia are also provided at the opposite sides from flanges 4 and 4a with secondary or auxiliary flanges 5 and 5a which are suitably molded in such a manner as to conform to the natural contour of the gums or jaws of a patient. These auxiliary flanges are also provided with apertures 8 the purposes of which are described below. Member I is provided with an inwardly disposed lug 6 and member Ia with a similarly inwardly turned lug 6a, the purposes of which are described below.
Member B is in the form of a wedge, the smaller 5 end 1 adapted to be inserted Within the box-like compartment I5 formed by the members I and la. Member B is also provided with a finger-piece 9 to which a cord may be attached for safety. A similar precaution may be taken with member A. 10 One of the converging faces of B is provided with beveled notches I0, the inclined faces of which are in the direction of the small end 1 of member B which is also provided with longitudinal groove I I on the other of its converging faces, the groove 5 stopping short of the overall length of said face as shown at I2 and I3. The entering end of B is provided with a rounded surface I4.
Referring now to the operation of the device and the co-acting of the parts, in use a suitable plastic, such as wax, is placed within the confines of the flanges 5 and 5a. of member A and the member is then inserted, spring end first, in the mouth cavity between the jaws, which come in contact therewith. The wax will be forced into conformation with the contour of the wearers jaw or teeth and thus allow individual adaptation of the jaw brace in all cases, especially in instances of edentulous, partial or full dentition. By reason of entering the apertures in the flanges the wax or cushion will become attached to the flanges 5 and 5a and form a firm and suitable seat for the teeth or gums in connection with member A.
Member B is then inserted and forced into space I5 between members I and la in such a manner as to spread members I and la apart. The degree of spread is determined by the distance that member B is inserted and by the degree of angularity of the wedge. Lug 6 will engage slot II and lug So will engage the beveled notches II), the foremost of which is in communication with an elongated V-shaped notch which acts as an entering notch and guide. It will be seen from this construction that. after spacer B is inserted as described above it will be impossible for the spacer to be dislodged unintentionally and the spacer will thus hold members I and la in any flxed predetermined separated position. When it is desired to release member B from its com- 5 partment, a slight tilting action on the fingerpiece will release lug So from the notches Ill, and the wedge can easily be withdrawn and members I and la allowed to resume their original positions.
It is to be understood that in the drawing I have shown only one of aset of jaw-braces which include a right, set forth in the drawing, and a left jaw-brace.
Having thus described my invention, what I claim is:
