Abstract
A medication injection method and related device with a hollow drill bit for delivery of anesthetic or other medication through the hollow drill bit are disclosed. The device preferably includes a hollow drill bit, a disposable fluid dispenser, a handpiece, a handle, and a foot control pedal. The device can deliver anesthetic or other medication before, during and/or after drilling of a tooth or bone structure without removing the drill bit. The invention relates to an intraosseous and/or hard tissue drug delivery system that combines perforating and drug delivering functions in one device and one operation.
Claims20
A medication injection device comprising:
- a housing for grasping by an operator, wherein the housing has a distal end;
- a rotatable hollow drill bit mounted to the distal end of the housing, wherein the drill bit includes a bore therethrough, and wherein the drill bit is suitable for intraosseous drilling;
- means disposed in the housing for rotating the drill bit;
- and
- fluid dispensing means including a fluid reservoir stationarily mounted in the housing and means for supplying a controlled dose of medication fluid for intraossaous injection through the bore of the drill bit.
A medication injection device comprising:
- a housing for grasping by an operator, wherein the housing has a distal end;
- a rotatable hollow drill bit mounted to the distal end of the housing, wherein the drill bit includes a bore therethrough;
- means disposed in the housing for rotating the drill bit;
- and
- fluid dispensing means including a fluid reservoir stationarily mounted in the housing for supplying a medication fluid to the bore of the drill bit;
- wherein the hollow drill bit includes a hypodermic needle having a sharpened point.
A medication injection device comprising:
- a housing for grasping by an operator, wherein the housing has a distal end;
- a rotatable hollow drill bit mounted to the distal end of the housing, wherein the drill bit includes a bore therethrough;
- means disposed in the housing for rotating the drill bit;
- and

- and
- a duct extending through the housing between the fluid dispenser and the hollow drill bit.
A method of administering medication to a tissue, said method comprising the steps of:
- drilling an opening in said tissue with a hollow drill bit;
- injecting medication into said opening through the hollow drill bit while drilling;
- and
- further injecting medication into said opening through the hollow drill bit after the step of drilling has been completed.
A method of administering a medication comprising the steps of:
- providing a drilling apparatus having a reservoir of the medication, having a hollow drill bit and means for rotating the drill bit, and having a means for supplying the medication to the hollow drill bit;
- drilling an opening in a tissue with the hollow drill bit and injecting medication through the hollow drill bit while drilling;
- and
- injecting the medication through the hollow drill bit and the drilled opening into the tissue after the drilling step has been completed.
