Abstract
An anti-clog suction tip apparatus includes a suction tip having a suction opening and an interior defining a suction channel. An ejection wire channel extends to a wire exit opening into the suction channel that is located proximate the suction opening. An ejection wire including a ball tip at an end thereof occupies the ejection wire channel and is transitionable between a retracted configuration and an advanced configuration such that, in the retracted configuration, the ejection wire including the ball tip is retained within the ejection wire channel and does not obstruct suctioning of debris through the suction channel; and in the advanced configuration, the ball tip of the ejection wire does not extend more than three millimeters beyond the suction opening.
