Abstract
The present invention relates to a surgical drill guide having an anchoring mechanism for locking the drill guide to a bone plate. The anchoring mechanism is adapted to be received through an opening of a bone plate and rotated to lock the drill guide to the bone plate. The anchoring mechanism can be rotated by a driver, which has a distal end key that fits into a corresponding socket of on the proximal portion of the anchoring mechanism. The present invention also relates to a kit including a bone plate, a driver, and the drill guide and a method for using the kit to perform surgery.
Claims21
A drill guide comprising:
- a handle;
- a drill guide tube having an open proximal end, an open distal end, and a hollow lumen therebetween configured to receive a drill therethrough;
- a distal planar portion comprising:
- a proximal face, a distal face, and a hole therethrough;
- and
- a rotatable anchoring member received within the hole of the distal planar portion, the anchoring member comprising:
- a proximal portion having a socket and distal portion having a flared distal end,
- wherein the open distal end of the drill guide tube is configured to align with a screw hole of a bone plate such that a hole can be drilled into bone through the screw hole,
- wherein the distal face of the distal planar portion is configured to contact a front surface of the bone plate, and
- wherein the flared distal end of the anchoring member is configured to align with an opening in the bone plate and lock the drill guide to the bone plate upon rotation of the anchoring member.
A drill guide comprising:
- a handle;
- a first drill guide tube having an open proximal end, an open distal end, and a hollow lumen therebetween configured to receive a drill therethrough;
- a second drill guide tube having an open proximal end, an open distal end, and a hollow lumen therebetween configured to receive a drill therethrough;
- a bridge portion connecting the distal end of the first drill guide tube and the distal end of the second drill guide tube, the bridge portion comprising:
- a proximal face, a distal face, and a hole therethrough;
- and
- a rotatable anchoring member received within the hole of the bridge portion, the rotatable anchoring member comprising:
- a proximal portion having a socket and distal portion having a flared distal end,
- wherein the distal ends of the drill guide tubes are configured to align with screw holes of a bone plate such that a hole can be drilled into bone through the screw holes,
- wherein the distal face of the bridge portion is configured to contact a front surface of the bone plate, and
- wherein the flared distal end of the anchoring member is configured to align with an opening in the bone plate and lock the drill guide to the bone plate upon rotation of the anchoring member.
A surgical kit comprising:
- a bone plate comprising:
- a front surface and a back surface, the back surface adapted to contact a bone;
- a plurality of screw holes each configured to receive a screw therethrough;
- an opening for receiving an anchoring member therein;
- and
- a drill guide comprising:
- a handle;
- a first drill guide tube having an open proximal end, an open distal end, and a hollow lumen therebetween configured to receive a drill therethrough;
- a second drill guide tube having an open proximal end, an open distal end, and a hollow lumen therebetween configured to receive a drill therethrough;
- a bridge portion connecting the distal end of the first drill guide tube and the distal end of the second drill guide tube, the bridge portion comprising:
- a proximal face, a distal face, and a hole therethrough;
- and
- a rotatable anchoring member received within the hole of the bridge portion, the rotatable anchoring member comprising:
- a proximal portion having a socket and distal portion having a flared distal end,
- wherein the distal ends of the drill guide tubes align with screw holes of the bone plate during use,
- wherein the distal face of the bridge portion contacts the front surface of the bone plate during use, and
- wherein the flared distal end of the anchoring member aligns with the opening in the bone plate during use and locks the drill guide to the bone plate upon rotation of the anchoring member.
A surgical kit comprising:
- a driver comprising:
- a handle at a proximal end, and a key at a distal end;
- a bone plate comprising:
- a front surface and a back surface, the back surface adapted to contact a bone;
- a plurality of screw holes each configured to receive a screw therethrough;
- at least one screw lock, wherein the at least one screw lock comprises a socket to turn the screw lock between a locked position and an unlocked position, wherein the key of the driver is sized to engage the socket of the screw locks;
- a plurality of screws having a head and a threaded shaft, each screw comprising a socket on the head thereof, wherein the key of the driver is sized to engage the socket of the screws.
