Abstract:
1. An apparatus for anchoring a rod to a bone fastener, comprising: a first resilient insert comprising: a second resilient insert insertable independent from the first resilient insert, the second resilient insert comprising: a cylindrical body having a passage between a first end and a second end thereof, wherein the passage in the cylindrical body has an inner diameter, wherein the second end of the cylindrical body comprises two recessed portions, wherein each recessed portion has an associated width greater than the diameter of the rod; wherein the first resilient insert has a width greater than the inner diameter of the cylindrical body when the first resilient insert is in a neutral state, wherein advancement of the first resilient insert into the passage in the cylindrical body deflects the first set of two deflectable arms inward, causing the width of the first channel to decrease, thereby holding the rod at the first end of the cylindrical body and inhibiting the first resilient insert from moving relative to the cylindrical body, and wherein the second resilient insert has a width greater than the inner diameter of the cylindrical body when the second resilient insert is in a neutral state, wherein advancement of the second resilient insert into the passage in the cylindrical body deflects the second set of two deflectable arms inward, causing the width of the second channel to decrease, thereby holding the bone fastener at the second end of the cylindrical body and inhibiting the second resilient insert from moving relative to the cylindrical body.
