摘要：
A suction device includes an elongated suction tube having a suction tip at a distal end thereof, and a proximal end that is connectable to a suction source. A collar is slidable along the suction tube from a retracted position to a deployed position. A sleeve is provided having a proximal end fixed relative to the proximal end of the suction tube, and a distal end configured with the collar so as to move therewith and cover the suction tube in the deployed position of the collar. A wiper seal is contained within collar in sliding frictional engagement around the suction tube.
