Abstract

An interbody implant system is provided. The interbody implant system includes an implant having an engagement surface and an instrument including a first member and a second member that is movable relative to the first member. The first member is configured to capture the implant and the second member includes an interface configured to engage the engagement surface to releasably lock the implant in at least one orientation relative to the second member. The at least one of the engagement surface and the interface include at least one planar face. Methods of use are disclosed.

Claims (33)

1. An interbody implant system comprising:

an implant having an engagement surface and a catch; and

an instrument extending along a longitudinal axis between opposite proximal and distal ends and including a first member and a second member that is movable relative to the first member, the first member comprising a top portion and a bottom portion that is movable relative to the top portion along the longitudinal axis, the top and bottom portions defining a capture surface configured to capture the catch, the second member including an interface configured to engage the engagement surface to releasably lock the implant in at least one orientation relative to the second member,

wherein at least one of the engagement surface and the interface include at least one planar face, and

wherein the second member comprises a first recess having a first spring disposed therein, a second recess that is spaced apart from the first recess having a second spring disposed therein, a notch and an arm that is pivotable relative to a body of the second member, the arm being movable to move the springs between compressed and decompressed states to move the capture surface between an open position to release the implant and a closed position to capture the implant during movement of the implant relative to the second member.

2. The implant system of claim 1 , wherein the implant is configured for capture by the first member and rotation relative to the instrument to a plurality of orientations, the implant being releasably lockable by the second member in each of the plurality of orientations.

3. The implant system of claim 1 , wherein the at least one planar face includes a proximal face of the implant, the proximal face being disposed in a perpendicular orientation relative to a single straight central longitudinal axis of the implant.

4. The implant system of claim 3 , wherein the at least one planar face further includes a first lateral face that converges with the proximal face to form a first angle wherein the implant is pivotable relative to the first member via engagement of the first member with the first angle.

5. The implant system of claim 1 , wherein the at least one planar face includes opposing lateral faces of the implant, the lateral faces being disposed in a parallel orientation relative to a single straight central longitudinal axis of the implant.

6. The implant system of claim 1 , wherein the at least one planar face includes opposing lateral faces of the implant, the lateral faces being disposed at an angular orientation relative to a single straight central longitudinal axis of the implant.

7. The implant system of claim 1 , wherein the at least one planar face includes a distal face of the second member, the distal face being disposed in a perpendicular orientation relative to a longitudinal axis of the instrument, the longitudinal axis being a single straight central longitudinal axis.

8. The implant system of claim 1 , wherein the catch includes a pin and the capture surface includes a cavity defined in a distal end of the second member.

9. The implant system of claim 1 , wherein the catch includes a pin and the capture surface includes a hook and an elongated gate movable to fix the pin in the hook.

10. The implant system of claim 1 , wherein the capture surface is biased to at least one of the open and closed positions.

11. The implant system of claim 1 , wherein the implant is configured for capture by the first member and rotation relative to the second member in one direction only.

12. The implant system of claim 1 , wherein the longitudinal axis is a single straight central longitudinal axis.

13. The implant system of claim 1 , wherein the first spring is disposed in a parallel orientation relative to the longitudinal axis and the second spring is disposed in a perpendicular orientation relative to the longitudinal axis.

14. The implant system of claim 1 , wherein a distal end of the arm is removed from the notch, the first spring is decompressed and a proximal end of the arm is disposed within the second recess when the capture surface is in the closed position.

15. The implant system of claim 1 , wherein a distal end of the arm is positioned within the notch, the first spring is compressed and a proximal end of the arm is removed from the second recess when the capture surface is in the open position.

16. An interbody implant system comprising:

an implant having a first end and a second end having an engagement surface including at least one planar face and a catch; and

an instrument extending along a longitudinal axis between a first end and a second end, the instrument being movable relative to a first member, the first member including a proximal end and a distal end, the first member including a top portion and a bottom portion that is movable relative to the top portion along the longitudinal axis, the top and bottom portions defining a capture surface configured to engage the catch,

a second member including a proximal end and a distal end, the distal end including a planar interface configured to engage the at least one planar face of the engagement surface to releasably fix the implant relative to the distal end of the second member in one of the plurality of orientations between a first configuration such that the distal end of the second member is movable relative to the implant and a second configuration to capture the catch such that the implant is movable relative to the second member to a plurality of orientations,

wherein the second member comprises a first recess having a first spring disposed therein, a second recess that is spaced apart from the first recess having a second spring disposed therein, a notch and an arm that is pivotable relative to a body of the second member, the arm being movable to move the springs between compressed and decompressed states to move the capture surface between the first configuration to release the implant and the second configuration to capture the implant during movement of the implant relative to the second member.

17. The implant system of claim 16 , wherein the at least one planar face includes opposing lateral faces of the implant, the lateral faces being disposed at an angular orientation relative to a single straight central longitudinal axis of the implant.

18. The implant system of claim 16 , wherein the at least one planar face includes a proximal face of the implant disposed in a perpendicular orientation relative to a single straight central longitudinal axis of the implant, and a first lateral face that converges with the proximal face to form a first angle, the implant being pivotable relative to the first member via engagement of the first member with the first angle.

19. An interbody implant system comprising:

a body defining a longitudinal axis extending between a proximal end surface and a distal end surface, said proximal and distal end surfaces extending between opposite top and bottom surfaces, said body comprising opposite first and second planar side surfaces that extend between said proximal and distal surfaces and said top and bottom surfaces, said first and second side planar surfaces extending parallel to one another, said body comprising a proximal end including an inner surface having opposing transverse surfaces, said inner surface defining an inner cavity having a proximal facing opening configured to receive an instrument, said proximal end further including a catch configured for disposal within the inner cavity and disposed in an orientation transverse to said longitudinal axis; and
