Spinal implant system and method
A surgical instrument comprises a first member including a drive engageable with a first mating surface of a bone fastener. A second member is rotatable relative to the first member and includes an engagement element connectable with a second mating surface of the bone fastener. Systems, spinal implants and methods are disclosed.
1. A surgical instrument comprising:
a first member including a drive engageable with a shaft of a bone fastener;
a second member being rotatable relative to the first member and including a screw connectable with a receiver of the bone fastener;
an implant support including extender tabs configured for engagement with the receiver; and
a guide member including an inner surface defining a cavity configured for disposal of a sleeve of the first member, the guide member including an image guide oriented relative to a sensor to communicate a signal representative of a position of the guide member,
wherein the screw is axially translatable relative to an inner shaft of the second member between a non-locking configuration and a locking configuration with a threaded surface of the bone fastener receiver.
2. A surgical instrument as recited in claim 1 , wherein the drive is integrally connected with the first member.
3. A surgical instrument as recited in claim 1 , wherein the drive comprises a distal tip of the first member and is configured for disposal in a drive socket of the shaft.
4. A surgical instrument as recited in claim 1 , wherein the first member includes a wall surface connectable with the implant support.
5. A surgical instrument as recited in claim 4 , wherein the wall surface includes mating grooves that are engageable with the extender tabs.
6. A surgical instrument as recited in claim 4 , wherein the wall surface defines a pocket surface engageable with proximal spring tips of the implant support.
7. A surgical instrument as recited in claim 1 , wherein the sleeve defines an inner cavity configured for disposal of the inner shaft.
8. A surgical instrument as recited in claim 7 , wherein the second member includes a rotatable actuator connected with the inner shaft.
9. A surgical instrument as recited in claim 8 , wherein the rotatable actuator includes a knurled wheel including an inner surface engageable with the inner shaft for rotation therewith.
10. A surgical instrument as recited in claim 7 , wherein the engagement element includes an inner surface engageable with the inner shaft for rotation therewith.
11. A surgical instrument as recited in claim 1 , wherein the screw has an outer thread surface connectable with a mating surface of the receiver.
12. A surgical instrument as recited in claim 1 , wherein the drive is integrally connected with a sleeve of the first member.
13. A spinal implant system comprising:
a surgical instrument including an outer tubular sleeve extending between a proximal end and a distal end including a drive engageable with a bone fastener shaft, and an inner shaft being rotatable relative to the sleeve and including a screw connectable with a threaded surface of a bone fastener receiver;
an implant support including extender tabs configured for engagement with the bone fastener receiver;
a guide member including an inner surface that defines a cavity configured for disposal of the sleeve and an image guide being oriented relative to a sensor to communicate a signal representative of a position of the guide member; and
a tracking device including a sensor that receives the signal and communicates with a processor to generate data for display of an image from a monitor, the image representing position of the guide member relative to tissue.
14. A spinal implant system as recited in claim 13 , wherein the guide member includes an end effector of a robotic arm.
15. A spinal implant system as recited in claim 13 , wherein the drive is integrally connected with the sleeve.
16. A spinal implant system as recited in claim 13 , wherein each extender tab includes proximal spring tips engageable with a pocket surface of the sleeve.
17. A spinal implant system as recited in claim 13 , wherein the screw is axially translatable relative to the inner shaft between a non-locking configuration and a locking configuration with the threaded surface of the bone fastener receiver.
18. A spinal implant system comprising:
a surgical instrument including an outer tubular sleeve extending between a proximal end and a distal end including a drive engageable with a bone fastener shaft, and an inner shaft being rotatable relative to the sleeve and including a screw connectable with a threaded surface of a bone fastener receiver;
an implant support including extender tabs configured for engagement with the bone fastener receiver; and
a guide member including an inner surface that defines a cavity configured for disposal of the sleeve and an image guide being oriented relative to a sensor to communicate a signal representative of a position of the guide member,
wherein each extender tab includes proximal spring tips engageable with a pocket surface of the sleeve.
19. A spinal implant system as recited in claim 18 , wherein the guide member includes an end effector of a robotic arm.
