Abstract:
1. An injection device comprising: a corkscrew injection needle including a proximal end and a distal end and a needle bore formed through the proximal and distal ends, the corkscrew needle including a linear proximal portion and a spiral distal portion, the corkscrew needle terminating with a sharpened tip at the distal end for penetrating and advancing through patient tissue; a needle hub being permanently inseparably formed and being non-rotatably and permanently rigidly coupled to and surrounding a portion of the linear proximal portion; an adapter coupled to the needle hub, the adapter including a proximal end and a distal portion with a distal end and an adapter bore formed through the proximal and distal ends, the distal end of the adapter inserted into a proximal end of the needle hub and having an outward snap-in flange portion engaging an interior shoulder of the needle hub with a continuously rotatable, fluid-tight fit sealed with an annular ring between an exterior surface of the distal portion and an interior surface of the needle hub; and a syringe connectable to the corkscrew needle via the adapter, the syringe including a barrel and a chamber formed therein for containing an injectable substance and a plunger slidably disposed within the barrel, the barrel having a proximal end, a distal end, and an outlet at the distal end in fluid communication with the chamber, the distal end of the syringe connectable to the proximal end of the adapter, the adapter bore providing fluid communication between the syringe chamber and the needle bore, the adapter allowing rotation of the corkscrew needle without rotating the syringe.
