Abstract

A surgical system includes an implant having a first attachment mechanism and an insertion instrument having a proximal end, a distal end, and a second attachment mechanism disposed at the distal end for removable connection with the first attachment mechanism. The proximal end of the insertion instrument is pivotable with respect to the implant. The insertion instrument can include an inserter and a guide. A method of using the surgical system is provided.

First claim

The invention claimed is:

1. A surgical system comprising:
an implant having a first attachment mechanism comprising an implant aperture, the implant aperture extending from a distal to a proximal face of the implant and disposed at a center of the implant along a central longitudinal axis of the implant; and
an insertion instrument having a proximal end, a distal end, and a second attachment mechanism disposed at the distal end for removable connection with the first attachment mechanism, the insertion instrument further including an inserter and a guide, the guide including the second attachment mechanism for connection with the first attachment mechanism, the guide including a proximal face and a continuous distal face with one or more apertures extending therebetween and configured to allow passage of a fastener, wherein the inserter is pivotally and removably connected with the guide, wherein the guide includes a pin and the inserter includes two clips configured to pivotally and removably grasp the pin through a channel in the proximal face of the guide, wherein the second attachment mechanism extends from the distal face of the guide and wherein the one or more apertures are laterally offset from the second attachment mechanism,
wherein the proximal end of the insertion instrument is pivotable with respect to the implant.

2. The system of claim 1 , wherein the inserter includes a sleeve movable from an unlocked position in which the sleeve is disengaged from the clips and the clips can move apart from one another to a locked position in which the sleeve overlaps at least a portion of the clips to at least partially prevent the clips from moving apart from one another.

3. The system of claim 1 , wherein the second attachment mechanism is a male feature and the first attachment mechanism is a female feature.

4. The system of claim 3 , wherein the male and female features are further secured with a ball-detent feature therebetween.

5. The system of claim 3 , wherein the male feature is a split shank and the female feature is an aperture configured to receive the split shank.

6. The system of claim 1 , wherein the guide is configured to be dedicated to a single configuration of the implant.

7. The system of claim 1 , wherein the guide is configured to be attachable to multiple different configurations of the implant.

8. The system of claim 1 , wherein the one or more apertures are configured to align with one or more screw holes of the implant.

9. The system of claim 1 , further comprising a second insertion instrument having a proximal end, a distal end, and a third attachment mechanism disposed at the distal end for connection with the first attachment mechanism, the second insertion instrument being an inserter directly engageable with the implant.

10. The system of claim 9 , wherein the first attachment mechanism is configured to connect with both the second attachment mechanism and the third attachment mechanism.

11. The system of claim 1 , further comprising a screw for insertion through a screw hole of the implant.
