Surgical system and method
A surgical instrument includes a first member having a mating surface that is connectable with a first blade and a height controller. The height controller is connectable with a surgical distractor and configured to translate the first member relative to the surgical distractor. A second member includes a second blade and is movable relative to the first member such that the blades are movable to space tissue adjacent a spine. Surgical systems, constructs, implants and methods are disclosed.
1. A surgical instrument comprising:
a retractor comprising: a first member comprising a first arm and a second member comprising a second arm;
a surgical distractor; and
a height controller, the height controller being connectable with the distractor and the first member,
wherein the surgical distractor comprises a projection and the height controller includes a longitudinal rail defining a groove, the projection being disposed in the groove such that the height controller is configured to translate the first member relative to the surgical distractor to adjust a height of the retractor relative to the surgical distractor.
2. A surgical instrument as recited in claim 1 , wherein the height controller is slidably translatable along the surgical distractor.
3. A surgical instrument as recited in claim 1 , wherein the height controller is selectively fixable in a position relative to the surgical distractor.
4. A surgical instrument as recited in claim 3 , wherein the height controller is selectively fixable in the position via friction engagement with the surgical distractor.
5. A surgical instrument as recited in claim 1 , wherein the first arm defines an axis and the height controller extends transverse to the axis.
6. A surgical instrument as recited in claim 1 , wherein the first member is releasably engageable with the height controller via a mating connection.
7. A surgical instrument as recited in claim 1 , wherein the first member is releasably engageable with the height controller via a snap fit connection.
8. A surgical instrument as recited in claim 1 , wherein the first arm defines an axis and a first blade is rotatable about the axis.
9. A surgical instrument as recited in claim 8 , further comprising a handle connected with the first member for rotating the first blade about the axis.
10. A surgical instrument as recited in claim 8 , wherein:
the arm is a first arm, the axis is a first axis, and the second member includes a second arm defining a second axis; and
a second blade is rotatable about the second axis.
11. A surgical instrument as recited in claim 10 , wherein the members include a lock, to selectively fix the first blade relative to the second blade, or a ratchet.
12. A surgical system comprising:
a first implant support and a second implant support, the implant supports being engaged with bone fasteners fixed with vertebral tissue;
a surgical distractor engageable with the implant supports, the surgical distractor including a projection;
a surgical retractor having a first member including a mating surface connectable with a first blade and a second member including a second blade and being movable relative to the first member such that the blades are movable to space tissue adjacent a spine, the surgical retractor comprising a ratchet extending through the first member and connected to the second member; and
a height controller including longitudinal rails that define a groove, the groove being configured for disposal of the projection such that the projection is slidably translatable within the groove, the height controller being connectable with the first member,
wherein the height controller is configured to adjust the height of the surgical retractor relative to the surgical distractor.
13. A surgical system as recited in claim 12 , further comprising a stability element disposed with the implant supports and being alternately engageable with the first blade or the second blade.
14. A surgical system as recited in claim 13 , wherein the implant supports define rod slots configured for slidable translation of the stability element.
15. A surgical system as recited in claim 13 , wherein the stability element includes at least one mating pin being alternately engageable with the first blade or the second blade.
16. A surgical system comprising:
a first implant support and a second implant support, the implant supports being engaged with bone fasteners fixed with vertebral tissue, the first implant support defining a first rod slot and the second implant support defining a second rod slot;
a surgical retractor engageable with the implant supports, and including a first blade and a second blade; and
a stability element comprising opposite first and second end surfaces, the first end surface being disposed in the first rod slot and the second end surface being disposed in the second rod slot, the stability element comprising a section between the end surfaces, the section being coupled directly to one of the blades.
17. A surgical system as recited in claim 16 , wherein the rod slots are configured for slidable translation of the stability element.
18. A surgical system as recited in claim 16 , wherein the surgical retractor has a first member including a mating surface being alternately connectable with the first blade and a height controller, the height controller being connectable with a surgical distractor and configured to translate the first member relative to the surgical distractor, the surgical retractor further having a second member including the second blade and being movable relative to the first member such that the blades are movable to space tissue adjacent a spine.
19. A surgical system as recited in claim 18 , wherein the height controller is selectively fixable in a position relative to the surgical distractor.
20. A surgical instrument as recited in claim 1 , further comprising a ratchet extending through the first member and connected to the second member.
