    a biasing member biasing the needle cannula within the multi-slot aperture; and

    a sensing arm connected to the binding plate adapted to contact a portion of the needle cannula, and positionable for restricting movement of the needle cannula in a distal direction,wherein the multi-slot aperture comprises a first region having a first dimension, and a second region having a second dimension, the second dimension being smaller than the first dimension, and wherein the biasing member is adapted to advance the needle cannula within the multi-slot aperture from the first region to the second region, wherein upon advancement of the needle cannula within the multi-slot aperture by the biasing member, the binding plate is adapted to tilt and contact the needle cannula, thereby preventing movement of the needle cannula in a proximal direction.
