    a fluid path carried by the handpiece for conducting a liquid from a source external to the handpiece into the lumen of the follicle punch held by the handpiece for delivery of the fluid to the cutting edge of the follicle punch;

    an ejector pin positioned within the fluid path of the handpiece for axial movement from a retracted position to a deployed position within the follicle punch when the punch is held by the handpiece so as to eject an impacted graft or debris from the punch'"'"'s interior; and

    operator-controlled means for moving the pin axially between the retracted and deployed positions.
