Abstract: Certain embodiments provide an apparatus comprising a hand-piece, an outer tube coupled to the hand-piece, an inner tube housed within the outer tube and having a distal end coupled to a soft tip and a proximal end coupled to an adapter, a proximal end of the adapter coupled to a distal end of a valve, the valve slidably coupled to the hand-piece, and a core slidably coupled to the hand-piece and having a distal end coupled to a proximal end of the valve. To retract the soft tip, the valve is retracted, causing the adapter, the valve, and the core to slidably retract in a proximal direction in relation to the hand-piece, and to extend the soft tip, the valve is protracted, causing the adapter, the valve, and the core to slidably protract in a distal direction in relation to the hand-piece.
