Abstract

See full text

A surgical instrument includes a movable member having a proximal portion, the movable member defining an opening at the proximal portion. The instrument includes a stationary member defining an aperture. The stationary member is arranged relative to the movable member with a close fit between the stationary member and the movable member such that aspiration occurs through the movable member substantially only during a portion of a repetitive motion of the movable member. The instrument includes a surgical handpiece coupled to the movable member and the stationary member to provide suction and motion to the movable member. A method of regulating aspiration through a surgical instrument includes providing a close fit between a moving member having an opening at a proximal portion and a stationary member having an aperture such that aspiration occurs through the moving member substantially only during a portion of a repetitive motion of the movable member. The moving member and the stationary member are coupled to a surgical handpiece to provide suction and motion to the moving member.
