Description

Mouse prop {Mouth prop}

The present invention relates to a mouse prop, in particular, it is sandwiched between the molar (molar) portion of the upper jaw (upper jaw) and the molar (molar) portion of the lower jaw (lower jaw), while allowing the patient to maintain the mouth open, and the lower jaw relatively. It is related to a mouse prop capable of moving forward to secure an airway.

The laryngoscope, which is mainly used to secure the airway for tracheal intubation, can cause tooth damage in the process of securing the airway because the maxillary anterior region is used as a support (Fulcrum) in the process of lifting the mandible and tongue.

In addition, recently, medical and dental treatments using sedation have been spotlighted in order to minimize the fears of patients and to promote cooperation. Sedation methods, unlike general anesthesia, secure airways and breathe spontaneously. It is the most important thing to do, and if it is not, it is a medical practice with possible medical accidents such as choking.

It is known that raising the chin after tilting the head back as a means for securing the airway is a priority method for securing the airway, because the rear airway obstruction may occur due to a decrease in the tension of the tongue when the consciousness is lowered.

However, in the case of dentistry, since the mouth is opened and treated using a tool such as a mouse prop that simply opens the mouth when treating under sedation, it is difficult to secure the airway and frequent occlusion of the posterior airway occurs.

On the other hand, there is a snoring prevention device as a dental device for treating snoring due to the problem of securing the posterior airway. This is a device using the principle of moving the mandible relative to the maxilla.

In addition, many devices such as Herbst, Frankel, and Twinblock are known as corrective devices that move the mandible forward to correct the relative position of the mandible. However, most of these are fixed or removable, and have a complicated configuration, limited use, and inconvenience in use.
