Abstract
An evacuation hand piece for collecting debris during dental procedures. The hand piece is adapted for attachment to evacuation apparatus and provides both intra- and extra-oral suction. A body member of the hand piece has a contoured outer gripping surface which makes the hand piece easier to grasp. A mask is disposed at one end of the hand piece to create a suction area which is larger than the cross sectional area of the body member. The mask is attached to a spherical tip of the body member to form a ball and socket-type connection which permits directional adjustment of the mask, thereby maximizing the effective extra-oral suction of the hand piece. The mask is formed from transparent material to allow viewing through the mask during dental procedures.
