Abstract

A surgical instrument comprises a first member connected with tissue. A second member is connected with the first member and configured to orient at least one surgical tool along at least one selected path for penetrating tissue. Systems and methods of use are disclosed.

First claim

What is claimed is:

1. A surgical instrument comprising:
a first member configured to be connected with tissue, the first member comprising a frame, a first collar coupled to a first end of the frame, a second collar coupled to a second end of the frame, a first paddle positioned within a cavity of the first collar and a second paddle positioned within a cavity of the second collar, the first member including a first rod extending from the first collar and a second rod extending from the second collar, the rods each being connected with a bone fastener that is configured to be attached with tissue; and
a second member connected with the first member and configured to orient at least one surgical tool along at least one selected path for penetrating tissue.

2. The surgical instrument recited in claim 1 , wherein the paddles each include a lip that is configured to engage tissue to stabilize the surgical instrument.

3. The surgical instrument recited in claim 1 , wherein the collars are movable relative to the frame.

4. The surgical instrument recited in claim 1 , wherein the frame includes a first part and a second part that is disposed in a telescoping configuration with the first part.

5. The surgical instrument recited in claim 1 , wherein the frame includes a lock positioned between the collars that includes spaced apart arms that define a cavity therebetween, a slide of the second member being positioned within the cavity of the lock, inner surfaces of the arms comprising a thread form configured to mate with a thread form of a set screw to fix the slide relative to the frame.

6. The surgical instrument recited in claim 1 , wherein the second member includes a guide configured for disposal of a surgical tool.

7. The surgical instrument recited in claim 6 , wherein the guide includes a first slide and a second slide, the slides being relatively movable.

8. The surgical instrument recited in claim 6 , wherein the guide includes at least one angled block.

9. The surgical instrument recited in claim 6 , wherein the guide is selectively adjustable to orient the surgical tool at a selected angle relative to the first member.

10. The surgical instrument recited in claim 6 , wherein the guide is axially translatable relative to the first member.

11. The surgical instrument recited in claim 1 , wherein the collars are each connected with the frame via a ball and socket.

12. A surgical instrument comprising:
a support configured to be connected with at least one vertebra, the support comprising a frame, a first collar coupled to a first end of the frame, a second collar coupled to an opposite second end of the frame, a first paddle positioned within a cavity of the first collar and a second paddle positioned within a cavity of the second collar, the paddles each being engageable with at least one vertebra to stabilize the surgical instrument, the support including a first rod extending from the first collar and a second rod extending from the second collar, the rods each being connected with a bone fastener that is configured to be attached with tissue;
an arm positioned within a receiver of the frame; and
a guide connected with the arm and being configured to orient a surgical tool along at least one selected path for penetrating at least one vertebra.

13. The surgical instrument recited in claim 12 , wherein the support is configured to be connected with the at least one vertebra via at least one bone fastener.

14. A surgical instrument comprising:
a support comprising a frame, a first collar coupled to a first end of the frame, a second collar coupled to a second end of the frame, a first paddle positioned within a cavity of the first collar and a second paddle positioned within a cavity of the second collar, the collars each being connected with the frame via a ball and socket;
a slide positioned within a receiver of the frame; and
a guide connected with the slide and being movable relative to the slide to orient a surgical tool along a selected path,
wherein the receiver is positioned between the collars, the receiver including spaced apart arms that define a cavity therebetween, the slide being positioned within the cavity of the receiver, inner surfaces of the arms comprising a thread form configured to mate with a thread form of a set screw to fix the slide relative to the frame.

15. The surgical instrument recited in claim 14 , wherein the slide includes a cavity and the guide includes a first part and a second part that is movable relative to the first part, the parts being positioned within the cavity of the slide.

16. The surgical instrument recited in claim 15 , wherein the parts are connected via a pin and slot engagement.

17. The surgical instrument recited in claim 15 , wherein the first part includes a first passageway and the second part includes a second passageway that is similarly oriented relative to the slide.

18. The surgical instrument recited in claim 15 , further comprising an insert positioned within the cavity of the slide such that the insert is rotatable relative to the slide, the parts being positioned within the insert.
