Drill guide pin, shank, cannulated drill bit, and driver for creating a hole in a bone
First Claim
1. A dental implant drilling system for implanting a dental implant in bone tissue using an implant drill driver, comprising:
- a shank removably coupleable to the implant drill driver, the shank comprising a circumferentially enclosed internal passage having a non-round cross-sectional shape and a driver engagement portion comprising a first notched section, wherein when coupled to the implant drill driver, the shank is rotatable via operation of the implant drill driver;
a drill guide pin comprising a bone penetrating end portion, a shank engagement end portion opposing the bone penetrating end portion, and an elongate shaft, the shank engagement portion comprising a second notched section having a non-round cross-sectional shape corresponding with the non-round cross-sectional shape of the internal passage of the shank, wherein the elongate shaft extends between the bone penetrating end portion and the second notched section, and wherein an intersection of the second notched section and elongate shaft comprises a stop that engages the shank to prevent axial movement of the drill guide pin relative to the shank; and
a cannulated drill bit, wherein the drill guide pin is configured to receive thereabout the cannulated drill bit, and wherein the cannulated drill bit is removably coupleable to the implant drill driver;
wherein the second notched section of the shank engagement portion is removably insertable within the internal passage of the shank, and wherein when the second notched section is inserted within the internal passage of the shank, engagement between the second notched section and the internal passage facilitates co-rotation of the shank and drill guide pin.

Abstract
According to one embodiment, a dental implant system for implanting a dental implant in bone tissue using an implant drill driver includes a shank and a drill guide. The shank is removably coupleable to the implant drill driver and includes an internal passage that has a non-round cross-sectional shape. When coupled to the implant drill driver, the shank is rotatable via operation of the implant drill driver. The drill guide pin includes a bone penetrating end portion and a shank engagement portion. The shank engagement portion includes a notched section having a non-round cross-sectional shape corresponding with the non-round cross-sectional shape of the internal passage of the shank. The notched section of the shank engagement portion is insertable within the internal passage of the shank. Moreover, engagement between the notched section and the internal passage facilitates co-rotation of the shank and drill guide pin.

12. A method for drilling bone tissue, comprising:
-
removably coupling a shank to a bone drill driver, the shank comprising an internal passage having circumferentially enclosed non-round cross-sectional shape extending an entire length of the shank and a driver engagement portion comprising a notched section; inserting a shank engagement portion of a guide pin into the internal passage of the shank until a stop formed in the guide pin contacts an end of the shank to prevent further axial movement of the guide pin along the internal passage, the shank engagement portion comprising a keyed-in section having a non-round cross-sectional shape matching the non-round cross-sectional shape of the internal passage of the shank; with the keyed-in section inserted within the internal passage of the shank, co-rotating the shank and the guide pin via actuation of the bone drill driver and engagement between the keyed-in section of the shank engagement portion of the guide pin and the internal passage of the shank; driving the guide pin into bone tissue; removing the shank engagement portion of the guide pin from the internal passage of the shank; decoupling the shank from the bone drill driver; removably coupling a cannulated drill bit to the bone drill driver; positioning the guide pin through the cannulated drill bit; rotating the cannulated drill bit via actuation of the bone drill driver; and driving the cannulated drill bit into bone tissue surrounding the guide pin.

13. A dental implant drilling system for implanting a dental implant in bone tissue using an implant drill driver, comprising:
-
a shank removably coupleable to the implant drill driver, the shank comprising a circumferentially enclosed internal passage having a non-round cross-sectional shape and a driver engagement portion comprising a first notched section, wherein when coupled to the implant drill driver, the shank is rotatable via operation of the implant drill driver; and a drill guide pin comprising a bone penetrating end portion, a shank engagement end portion opposing the bone penetrating end portion, and an elongate shaft, the shank engagement portion comprising a second notched section having a non-round cross-sectional shape corresponding with the non-round cross-sectional shape of the internal passage of the shank, wherein the elongate shaft extends between the bone penetrating end portion and the second notched section, wherein an intersection of the second notched section and elongate shaft comprises a stop that engages the shank to prevent axial movement of the drill guide pin relative to the shank, and wherein the guide pin is fluteless; wherein the second notched section of the shank engagement portion is removably insertable within the internal passage of the shank, and wherein when the second notched section is inserted within the internal passage of the shank, engagement between the second notched section and the internal passage facilitates co-rotation of the shank and drill guide pin.
