1. A device, comprising:
a needle;
a syringe coupled to the needle, wherein the syringe comprises a barrel and a plunger slidably disposed in the barrel;
an electric motor coupled to the needle to rotate the needle;
a gear assembly coupling the needle to the electric motor to cause reciprocal axial translation of the needle; and
a movable activation mechanism configured to permit one handed operation or a single one finger motion which starts the motor and moves the plunger relative to the barrel thereby pulling a vacuum in the needle.
