Abstract

The invention discloses an oral cavity supporting device of an adjustable tongue retaining plate and relate to a dental auxiliary medical apparatus. The oral cavity supporting device has the functionsof distracting the oral cavity and preventing disturbance of the tongue. The oral cavity supporting device comprises an oral cavity supporting device body, the adjustable tongue retaining plate, a fixed length tongue retaining plate and a bidirectional lead screw, wherein when the oral cavity supporting device body is placed on one side of the oral cavity, the adjustable tongue retaining plate isconnected to the oral cavity supporting device body and a height adjusting rotary knob is connected to the middle of the bidirectional lead screw to adjust the height of the oral cavity supporting device body; a positioning rod is used for fixing corresponding positions of upper and lower parts of the oral cavity supporting device when the longitudinal height is adjusted. The oral cavity supporting device is I-shaped, the engaging part is of a concave arc shape, and the stress of the I-shaped structure is more centralized during engagement; the adjustable tongue retaining plate is of an embedded telescopic structure and a tongue retaining plate body is inserted into a tongue retaining sleeve to form the tongue retaining plate. The depth, inserted into the tongue retaining plate sleeve, ofthe tongue retaining plate is adjusted through three length adjusting holes. Balls on a V-shaped positioning elastic sheet are sunken into the three length adjusting holes to adjust and fix the stretching length of the tongue retaining plate body.
