Abstract:
1. A rotatable drilling device for use in injecting medication, said rotatable drilling device comprising: a) a rotatable hollow drill bit, wherein the rotatable hollow drill bit includes a first hub and a needle having a first outer diameter extending outwardly from an end of the first hub, the first hub being immovably affixed to the needle so that when the first hub is rotated, the needle is rotated with the first hub, wherein the needle has a sharp tip at an end, wherein the rotatable hollow drill bit has a bore extending therethrough through which medication can be introduced into the bore; and, b) an adapter having a rod at a lower end for removable insertion in the bore of the rotatable hollow drill bit, wherein the rod when inserted into the bore extends into and through the needle for substantially preventing debris from entering the needle and blocking the bore when drilling, wherein the adapter has an upper end for directly removably coupling with a motorized handpiece and has a second hub immovably coupled with the rod for directly mating with the first hub of the rotatable hollow drill bit, so as to impart rotational motion to the rotatable hollow drill bit when the upper end of the upper end of the adapter is rotated by the motorized handpiece.
