Offset variable angle connection assembly

摘要

Systems for securely connecting a spinal implant to a bone anchor by using an offset connection assembly. The variable angle connection assembly is able to securely connect the spinal implant to the anchors even when there is a variance in the angle and position of the anchors with respect to the spinal implant. The connection assembly will not inadvertently lock the components of the connection assembly preventing the relative movement of the components.

1. A system for securing a spinal implant to a bone anchor, the system comprising:
an anchor configured to be implanted into a vertebral body; a spinal implant; and a connection assembly comprising a housing member and a receiving member, the housing member having a first end and a second end, the housing member having an aperture proximate the first end for receiving a portion of the spinal implant, and the receiving member having a first end and a second end, the receiving member having an aperture for receiving a portion of the anchor and a resilient leg for contacting the anchor, wherein the receiving member is rotatably connected to the housing member, wherein the connection assembly further comprises a connection member having a first end and a second end, the connection member having a lumen, the lumen is in fluid communication with the aperture of the housing member and oriented generally transversely to the aperture of the housing member, the second end of the connection member is received in a channel of the housing member so that the connection member is rotatably and translatably connected to the housing member.
