Peripheral peg drill component
View Patent ↗A peripheral peg drill component comprising a housing having a first side and a second side opposite the first side, at least two drill bits extending from the second side of the housing, a defined opening on the second side of the housing, the defined opening being configured to receive an alignment pin extending from a bony surface, and a driving mechanism within the housing, the driving mechanism being configured to rotate the at least two drill bits and cause them to simultaneously penetrate the bony surface.
1. A peripheral peg drill component, comprising:
a housing having a first side and a second side opposite the first side;
at least two drill bits extending from the second side of the housing,
a defined opening on the second side of the housing, the defined opening being configured to receive an alignment pin extending from a bony surface; and
a driving mechanism within the housing, the driving mechanism being configured to rotate the at least two drill bits and cause them to simultaneously penetrate the bony surface, wherein the driving mechanism is a spur gear system having a drive gear, at least two driven gears and at least two idler gears, each idler gear of which is positioned between the drive gear and one of the at least two driven gears.
2. The peripheral peg drill component of claim 1 , wherein the at least two driven gears are each independently associated with and configured to simultaneously rotate in the same direction as one of the at least two drill bits.
3. The peripheral peg drill component of claim 1 , wherein the at least two drill bits are configured to collapse into the housing as the bony surface is engaged.
4. The peripheral peg drill component of claim 1 , further comprising a drive shaft releasably coupled to the first side of the housing, the drive shaft being connectable to a drill and configured to actuate the driving mechanism in response to the drill.
5. A peripheral peg drill component, comprising:
a housing having a first side and a second side opposite the first side;
at least two drill bits extending from the second side of the housing,
a movable boss associated with the second side of the housing, the movable boss defining an opening that is configured to receive an alignment pin extending from a bony surface;
a driving mechanism within the housing; and
a drive shaft actuatable by a drill and configured to cause the driving mechanism to rotate the at least two drill bits so that they simultaneously penetrate the bony surface.
6. The peripheral peg drill component of claim 5 , wherein the driving mechanism is a spur gear system having a drive gear and at least two driven gears.
7. The peripheral peg drill component of claim 6 , wherein the at least two driven gears are each independently associated with and configured to simultaneously rotate in the same direction as one of the at least two drill bits.
8. The peripheral peg drill component of claim 5 , wherein the driving mechanism is a spur gear system having a drive gear, at least two driven gears and at least two idler gears, each idler gear of which is positioned between the drive gear and one of the at least two driven gears.
9. The peripheral peg drill component of claim 8 , wherein the at least two driven gears are each independently associated with and configured to simultaneously rotate in the same direction as one of the at least two drill bits.
10. The peripheral peg drill component of claim 5 , wherein the movable boss further comprises a compression spring that is configured to assist with moving the boss from a first position within the housing to a second position outside of the housing.
11. The peripheral peg drill component of claim 10 , wherein the movable boss is configured to unitarily collapse the at least two drill bits into the housing as the bony surface is engaged.
