Title
(EN) DISPOSABLE DENTAL PROPHYLAXIS HANDPIECE
(FR) PIECE A MAIN JETABLE POUR PROPHYLAXIE DENTAIRE
Abstract
(EN)
A disposable dental prophylaxis handpiece (10) is provided having a rotor (90) with vanes (92) pivotally connected thereto. The handpiece (10) includes an entrance (30) for elevated pressure fluid and an outlet (40) for discharge of the fluid after contacting the rotor (90). The elevated pressure fluid passes from the entrance (30) into a high-pressure chamber (80). The high-pressure chamber (80) is in contact with inlet ports (74) accessing a cylinder (72) within the handpiece (10). The cylinder (72) supports the rotor (90) with a rotational axis (M) of the rotor (90) off center with respect to a central axis (N) of the cylinder (72). The elevated pressure fluid causes the rotor (90) and an attached output shaft (97) to rotate. This in turn causes a prophylaxis cup (160), coupled to the output shaft (97), to rotate. The rotor (90) includes a trunk (2) with a plurality of posts (93) extending therefrom and with vanes (92) connected to the posts (93) through hinges (94).
(FR)
La pièce à main jetable pour prophylaxie dentaire (10) de la présente invention est pourvue d'un rotor (90) comportant des ailettes (92) fixées par pivot. La pièce à main (10) comporte une entrée (30) de fluide haute pression, et une sortie (40) d'évacuation du fluide après contact avec le rotor (90). Le fluide haute pression admis par l'entrée (30) pénètre dans une chambre haute pression (80). La chambre haute pression (80) est en contact avec des orifices d'entrée (74) pénétrant dans un cylindre (72) situé à l'intérieur de la pièce à main (10). Le cylindre (72) supporte le rotor (90), l'axe de rotation (M) du rotor (90) étant décentré par rapport à l'axe central (N) du cylindre (72). Le fluide haute pression entraîne la rotation du rotor (90) et d'un axe de sortie (97) qui lui est solidaire. Cette rotation entraîne à son tour la rotation d'une cupule à polir (160) couplée à l'axe de sortie (97). Le rotor (90) est constitué d'une colonne (24) dont dépassent plusieurs supports (93), les ailettes (92) étant fixées aux supports (93) par des charnières (94).
