Disposable anesthesia delivery system with shortened outer sleeve and inner solid drill
First Claim
1. A dental apparatus for intraosseously delivering dental anesthesia comprising:
- a drilling member including a drill housing, a connecting portion for establishing a connection to a dental drilling apparatus, and a drill extending from the drill housing; and
a sleeve member including a sleeve housing, and a hollow sleeve extending from the sleeve housing;
wherein the sleeve housing is adapted to be removably engaged with the drill housing such that the drill is inserted into the sleeve;
wherein the drill has a length such that when the drill is inserted into the hollow sleeve, a portion of the drill extends beyond the hollow sleeve;
wherein the drill and the hollow sleeve are rotatable by the dental drilling apparatus, the drill comprises a cutting edge that drills a hole in bone, and the hollow sleeve comprises a leading edge that reams a proximal portion of the hole drilled by the drill;
wherein the hollow sleeve is adapted to receive a syringe needle when the sleeve housing and the drill housing are disengaged and the drill is removed from the hollow sleeve; and
wherein the drill is solid and has a smooth outer surface.

Abstract
An intraosseous delivery apparatus having a drilling member and a sleeve member. The drilling member includes a drill housing, a connecting portion for establishing a connection to a conventional dental drilling apparatus, and a drill extending from the drill housing. The sleeve member includes a sleeve housing, and a hollow sleeve extending from the sleeve housing. The sleeve housing is adapted to be removably engaged with the drill housing such that the drill is inserted into the hollow sleeve. The drill has a length such that when the drill is inserted into the hollow sleeve, a portion of the drill extends beyond the hollow sleeve. As a result, when the drill is used to drill a hole in bone, the drill is inserted deeper into the hole than the hollow sleeve. The hollow sleeve is adapted to be left inserted in the bone when the drill is removed therefrom. The “in place” hollow sleeve is also adapted to receive a syringe needle through which anesthesia may be directly introduced into the bone via an exposed bottom portion of the drilled hole as well as via exposed side-wall portions of the drilled hole. The drill is preferably smooth, and may also be hollow so that debris generated during drilling enters the interior of the drill. In this case, when the hollow drill is removed from the hollow sleeve, the debris within the hollow drill may also be removed

12. A dental method of intraosseously delivering dental anesthesia comprising the steps of:
-
removably coupling a drilling member and a sleeve member such that a drill housing of the drilling member and a sleeve housing of the sleeve member are removably engaged, and such that a solid drill having a smooth outer surface and extending from the drill housing is inserted into a hollow sleeve extending from the sleeve housing;
removably engaging a connecting portion of the drilling member to a dental drilling apparatus;
operating the dental drilling apparatus to cause the drill to drill a hole in a bone and the hollow sleeve to ream the drilled hole, thereby inserting the drill and the hollow sleeve into the bone, said drill having a length such that a portion thereof extends beyond the hollow sleeve and is inserted deeper into the drilled hole than the hollow sleeve;
disengaging the drill housing and the sleeve housing such that the drill is removed from the hollow sleeve and the hollow sleeve is left inserted in the bone;
inserting a syringe needle into the hollow sleeve left inserted in the bone; and
introducing a fluid from the syringe needle directly into the bone via an exposed bottom portion of the drilled hole as well as via exposed side-wall portions at a distal end of the drilled hole. - View Dependent Claims (13, 14, 15, 16, 17)
