Abstract

A method for simultaneously drilling at least two peripheral peg holes in a bony surface comprising providing a peripheral peg drill component including a housing with a first side, a second side opposite the first side and at least two drill bits extending from the second side of the housing; advancing the peripheral peg drill component over an alignment pin extending from a bony surface until each of the at least two drill bits engage the bony surface; actuating a belt circumferentially surrounding a series of pulleys to cause the at least two drill bits to rotate; and simultaneously penetrating the bony surface with the at least two drill bits as they rotate.

First claim

What is claimed is:

1. A method for simultaneously drilling at least two peripheral peg holes in a bony surface, the method comprising:
providing a peripheral peg drill component including a housing with a first side, a second side opposite the first side and at least two drill bits extending from the second side of the housing;
advancing the peripheral peg drill component over an alignment pin extending from a bony surface until each of the at least two drill bits engage the bony surface;
actuating a belt circumferentially surrounding a series of pulleys to cause the at least two drill bits to rotate; and
simultaneously penetrating the bony surface with the at least two drill bits as they rotate.

2. The method of claim 1 , further comprising the step of releasably coupling the first side of the peripheral peg drill component to a drilling device.

3. The method of claim 1 , wherein the step of actuating a belt circumferentially surrounding a series of pulleys comprises actuating a driver pulley and at least two driven pulleys located inside the housing, each driven pulley being independently associated with and configured to simultaneously rotate in the same direction as one of the at least two drill bits.

4. The method of claim 1 , further comprising the step of collapsing the at least two drill bits into the housing as the bony surface is engaged.

5. The method of claim 1 , wherein the step of advancing the peripheral peg drill component over the alignment pin comprises advancing a movable boss over the alignment pin, the movable boss further having a compression spring that is configured to assist with moving the boss from a first position located within the housing to a second position located outside of the housing.

6. The method of claim 1 , wherein the step of advancing the peripheral peg drill component over an alignment pin comprises advancing the alignment pin through an opening on the second side of the housing.

7. A peripheral peg drill component, comprising:
a housing having a first side and a second side opposite the first side, the first and second sides of the housing being connected by a central opening;
at least two drill bits extending from the second side of the housing; and
a driving mechanism located within the housing, the driving mechanism including a series of pulleys and a belt that together are configured to rotate the at least two drill bits and cause them to simultaneously penetrate a bony surface.

8. The peripheral peg drill component of claim 7 , wherein the central opening is configured to receive an alignment pin extending from the bony surface.

9. The peripheral peg drill component of claim 7 , further comprising a drive shaft connection port extending above the first side of the housing.

10. The peripheral peg drill component of claim 9 , further comprising a drive shaft releasably coupled to the drive shaft connection port, the drive shaft being connectable to a drill and configured to actuate the driving mechanism in response to the drill.

11. The peripheral peg drill component of claim 7 , wherein the series of pulleys includes a driver pulley and at least two driven pulleys, each driven pulley being independently associated with and configured to simultaneously rotate in the same direction as one of the at least two drill bits.

12. The peripheral peg drill component of claim 7 , wherein the driving mechanism further comprises a series of pins that are configured to impact the amount of tension placed on the belt.

13. The peripheral peg drill component of claim 12 , wherein the belt circumferentially surrounds the series of pulleys and is positioned between the series of pulleys and the series of pins.

14. The peripheral peg drill component of claim 7 , wherein the at least two drill bits are configured to collapse into the housing as the bony surface is engaged.

15. A peripheral peg drill component, comprising:
a housing having a first side and a second side opposite the first side, the first and second sides of the housing being connected by a central opening;
at least two drill bits extending from the second side of the housing;
a series of pulleys including a driver pulley and at least two driven pulleys;
a belt circumferentially surrounding the series of pulleys; and
a drive shaft actuatable by a drill and configured to cause the series of pulleys and the belt to collectively rotate the at least two drill bits so that they simultaneously penetrate a bony surface.

16. The peripheral peg drill component of claim 15 , wherein each of the at least two driven pulleys are independently associated with and configured to simultaneously rotate in the same direction as one of the at least two drill bits.

17. The peripheral peg drill component of claim 15 , wherein the central opening is configured to receive an alignment pin extending from the bony surface.

18. The peripheral peg drill component of claim 15 , further comprising a series of pins that are configured to impact the amount of tension placed on the belt circumferentially surrounding the series of pulleys.

19. The peripheral peg drill component of claim 18 , wherein the belt circumferentially surrounds the series of pulleys and is positioned between the series of pulleys and the series of pins.

20. The peripheral peg drill component of claim 15 , wherein the at least two drill bits are configured to collapse into the housing as the bony surface is engaged.
