Abstract
A connection assembly configured to securely connect a spinal implant to a bone anchor. In particular, a variable angle connection assembly that 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. Furthermore, a connection assembly that will not inadvertently lock the components of the connection assembly preventing the relative movement of the components.
Claims17
A connection assembly comprising:
- a housing member having a first end and a second end, the housing member having an aperture for receiving a portion of a spinal implant and a channel extending from the second end towards the first end;
- a receiving member having a first end and a second end, the receiving member having an aperture for receiving an anchor and a lumen extending from the second end towards the first end, wherein the second end of the receiving member is received in the channel of the housing member;
- and
- a cap member having a lumen and an extension portion, wherein the channel of the housing member receives the extension portion of the cap member, wherein a portion of the receiving member is received in the lumen of the cap member.
A connection assembly comprising:
- a housing member having a first end and a second end, the housing member having an aperture for receiving a portion of a spinal implant and a channel extending from the second end towards the first end, wherein the channel is in fluid connection with the aperture;
- a receiving member having a first end and a second end, the receiving member having an aperture, a shoulder portion, and a rim portion, wherein the second end of the receiving member is received in the channel;
- a ring member having a first face and a second face, wherein the ring member is positioned over the receiving member and received in the channel;
- a cap member having a lumen for receiving the receiving member and an extension portion, wherein the extension portion of the cap member is received in the channel and contacts the first face of the ring member, wherein the channel includes at least one groove for receiving the at least one projection;
- and
- an anchor configured to be received in the aperture of the receiving member.
A connection assembly for connecting a spinal implant to an anchor, the connection assembly comprising:
- a housing member having a first end and a second end, the housing member having an aperture for receiving a portion of a spinal implant, an opening proximate the first end for receiving a securing member, and a channel extending from the second end towards the first end;
- a receiving member having a first end and a second end, the receiving member having an aperture, a shoulder portion, a rim portion, and a lumen, wherein the lumen is in fluid communication with the aperture, wherein the second end of the receiving member is received in the channel;
- a cap member having a lumen for receiving the receiving member and an extension portion;
- and
- an anchor configured to be received in the aperture of the receiving member.
