Abstract

A surgical instrument includes an actuator. A first member is connected with the actuator and is configured to engage a bone fastener that defines a first implant cavity and a second implant cavity. A second member is connected with the actuator and includes an implant engaging surface having a first portion movable along the first implant cavity and a second portion movable along the second implant cavity. Systems, spinal constructs, implants and methods are disclosed.

First claim

What is claimed is:

1. A surgical system comprising:
a bone fastener including a first arm, a second arm and a third arm, the first arm and the second arm defining a first implant cavity, the third arm and the second arm defining a second implant cavity;
an actuator;
a first member connected with the actuator and being configured to engage the bone fastener, the first member defining a first passageway aligned with the first implant cavity and a second passageway aligned with the second implant cavity; and
a second member connected with the actuator and including an implant engaging surface having a first portion movable along the first implant cavity and a second portion movable along the second implant cavity.

2. A surgical system as recited in claim 1 , wherein the implant engaging surface extends in a transverse orientation relative to the first member to engage at least one spinal rod.

3. A surgical system as recited in claim 1 , wherein the implant engaging surface includes a planar surface and extends in a transverse orientation relative to the first member.

4. A surgical system as recited in claim 1 , wherein the implant engaging surface is configured to simultaneously engage a spinal rod disposed with the first implant cavity and a spinal rod disposed with the second implant cavity.

5. A surgical system as recited in claim 1 , wherein the second member has a wall including the implant engaging surface such that the first portion is aligned with the second portion.

6. A surgical system as recited in claim 1 , wherein the second member has a first wall and a second wall spaced apart from the first wall, the walls including the implant engaging surface.

7. A surgical system as recited in claim 6 , wherein the first portion is aligned with the second portion.

8. A surgical system as recited in claim 1 , wherein the first member includes spaced apart inner extensions and the second member includes an outer sleeve that axially translates relative to the extensions to engage at least one spinal rod.

9. A surgical system as recited in claim 1 , wherein the first member includes extensions configured to releasably capture the bone fastener.

10. A surgical system as recited in claim 1 , wherein the first member includes movable extensions configured to releasably capture the first arm and the third arm.

11. A surgical system as recited in claim 1 , wherein the actuator includes a linkage connected with the second member to axially translate the second member relative to the first member.

12. A surgical system as recited in claim 1 , wherein the actuator includes a handle connected with a linkage that axially translates the second member relative to the first member.

13. A surgical system as recited in claim 12 , wherein the handle is resiliently biased to an open configuration.

14. A surgical system as recited in claim 12 , wherein the handle includes a ratchet.

15. A surgical system as recited in claim 1 , further comprising a first spinal rod disposed with the first implant cavity and a second spinal rod disposed with the second implant cavity, wherein the implant engaging surface is configured to simultaneously engage the first spinal rod and the second spinal rod.

16. A surgical system comprising:
a bone fastener including a first arm, a second arm and a third arm, the first arm and the second arm defining a first implant cavity, the third arm and the second arm defining a second implant cavity;
an actuator including a linkage;
a member connected with the actuator, the member comprising spaced apart extensions configured to engage the bone fastener, the member defining a first passageway aligned with the first implant cavity and a second passageway aligned with the second implant cavity; and
a sleeve connected with the linkage, the sleeve including a first wall and a second wall, the walls being axially translatable along the implant cavities to engage a spinal rod disposed with the first implant cavity and a spinal rod disposed with the second implant cavity.

17. A surgical system as recited in claim 16 , wherein the bone fastener includes a first arm and a second arm that define the first implant cavity, and a third arm and the second arm define the second implant cavity, the extensions being contractible to releasably capture the first arm and the third arm.

18. A surgical system as recited in claim 16 , wherein the actuator includes a handle connected with the linkage, the handle including a lock to dispose the sleeve in a selected position relative to the bone fastener.

19. A surgical system as recited in claim 16 , wherein the first wall includes a first portion of an implant engaging surface and the second wall includes a second portion of the implant engaging surface, the implant engaging surface configured to simultaneously engage the spinal rod disposed with the first implant cavity and the spinal rod disposed with the second implant cavity.

20. A surgical system as recited in claim 16 , wherein the first wall is spaced apart from the second wall.

21. A spinal implant system comprising:
a surgical instrument including an actuator connected with a first member and a second member, the second member including an implant engaging surface;
a bone fastener including a head having a first receiver that defines an implant cavity and a second receiver that defines an implant cavity, and a shaft engageable with tissue;
a first spinal rod disposable with the first receiver; and
a second spinal rod disposable with the second receiver,
the implant engaging surface having a first portion being movable along the first receiver to engage the first spinal rod and a second portion being movable along the second receiver to engage the second spinal rod.
