a handle body;
a cap assembly disposed at a proximal end of the handle body, wherein the cap assembly is configured to be releasably fixed to the stylet;
a cover disposed over at least a portion of the handle body; and
a lever assembly comprising a lever,
wherein the lever is operatively coupled to the cap assembly, and is configured to pivotably extend from an outer surface of the cover;
wherein a portion of the cap assembly is configured to rotate relative to the cover, to move between a first, docking mode and a second, extended mode,
wherein, in the second, extended mode, the lever is configured to pivot away from the handle body in response to translation of the portion of the cap assembly and the stylet in a distal direction, and
wherein the stylet is configured to retract in a proximal direction in response to the lever pivoting toward the handle body.
