Abstract: Disclosed embodiments include apparatuses, systems, and methods for engaging a stylet within a needle. In an illustrative embodiment, an apparatus includes a stylet configured to be insertable into a lumen of a needle via a proximal port of secured to a needle actuator secured to the needle; and an end cap fixably coupled to the stylet and configured to cover a proximal end of the needle actuator and to be movable relative to the needle actuator to enable an operator to withdraw the stylet from the lumen.

Abstract: Disclosed embodiments include apparatuses, systems, and methods for orienting a needle as it is coupled with an insertion device. In an illustrative embodiment, an apparatus includes a guide tube defining a lumen configured to slidably convey a needle from a proximal end of the guide tube to a distal end of the guide tube. The proximal end of the guide tube includes an asymmetrical outer cross-section. A needle actuator is configured to be coupled to a proximal end of the needle. The needle actuator includes an asymmetrical distal opening configured to receive the guide tube responsive to the needle actuator being oriented to cause a distal end of the needle to face in a desired direction.

Abstract: A full power portable vacuum cleaner having a charging base which may provide vacuuming function similar to a household dustpan may employ a concealed hose and a retractable cord. To meet various cleaning demands, the vacuum cleaner may operate with different function modes, including the dustpan mode (vacuum through a port at the bottom of the vacuum body) for planar surface vacuuming, and the cordless portable mode for on-spot vacuuming. The vacuum cleaner may further employ multiple power supplies, including an internal battery supply, wall power supply, or car power supply.
