Disclosed herein is a mandible protracting device. The mandible protracting device includes a tubular body having a front and a rear openings, a first baffle plate, a second baffle plate, a first pair of flanges and a second pair of flanges. The first baffle plate and the second baffle plate are respectively connected to the tubular body approximating the front opening of the tubular body, wherein the first baffle plate forms a first angle at least 100 degrees relative to the longitudinal direction of the tubular body. Moreover, the first pair of flanges and the second pair of flanges are respectively connected to the tubular body, wherein the first pair of flanges approximate the rear opening of the tubular body. The first and second pairs of flanges cooperatively form an upper and lower teeth groove, in which the lower teeth groove is disposed relatively forward the front opening of the tubular body, so that the mandible of a subject is protracted during the medical procedure.本揭示內容提供一種提顎裝置,包括一管狀本體,其包括一前開口和一後開口、一第一擋板、一第二擋板、一對第一凸緣和一對第二凸緣。第一擋板和第二擋板分別與管狀本體相接且接近所述前開口,其中第一擋板與管狀本體的長度方向形成至少100度的夾角。所述第一凸緣和第二凸緣分別與管狀本體相接,其中相對於第二凸緣,第一凸緣較接近後開口。再者,第一凸緣與第二凸緣共同界定出一上、下齒列槽;且相較於上齒列槽,下齒列槽較接近管狀本體的前開口,因而可使一個體的下顎前推。110‧‧‧管狀本體120‧‧‧第一擋板130‧‧‧第二擋板140‧‧‧第一凸緣150‧‧‧第二凸緣162‧‧‧上齒列槽164‧‧‧下齒列槽L‧‧‧長度方向S‧‧‧虛擬線A‧‧‧第一夾角B‧‧‧第二夾角
