Intervertebral spacer and plate
Embodiments herein are generally directed to spinal implants, systems, apparatuses, and components thereof that can be used in spinal fusion and/or stabilization procedures, as well as methods of installation. The spinal implants may include an intervertebral spacer and a plate member.
1. A surgical system comprising:
an implant comprising:
a first endplate;
a second endplate;
a first ramped body extending between the first endplate and the second endplate, wherein the first ramped body comprises at least one upwardly facing ramp engaging the first endplate and at least one downwardly facing ramp engaging the second endplate; and
an actuator in engagement with the first ramped body, wherein rotation of the actuator causes translation of the first ramped body, thereby causing expansion of the implant; and
an inserter configured to engage the implant,
wherein the inserter comprises an outer shaft and a distal engagement portion at non-zero angle relative to the outer shaft,
wherein a first engagement tip and a second engagement tip extend from the distal engagement portion, and
wherein the first engagement tip comprises a threaded shaft.
2. The surgical system of claim 1 , wherein the first engagement tip is in engagement with a drive shaft.
3. The surgical system of claim 2 , wherein the drive shaft is capable of rotation via a rotatable actuator.
4. The surgical system of claim 3 , wherein the rotatable actuator comprises a thumb wheel.
5. The surgical system of claim 1 , wherein the second engagement tip comprises a trilobular tip.
6. The surgical system of claim 5 , wherein the second engagement tip further comprises a spherical guide.
7. The surgical system of claim 6 , wherein the second engagement tip further comprises a spring positioned between the spherical guide and the trilobular tip.
8. The surgical system of claim 1 , wherein the first engagement tip is actuated by a drive shaft that is integrated into a body of the inserter.
9. The surgical system of claim 1 , wherein rotation of the second engagement tip causes expansion of the implant.
10. A surgical system comprising:
an implant comprising:
a first endplate;
a second endplate;
a first ramped body extending between the first endplate and the second endplate; and
an actuator in engagement with the first ramped body,
wherein rotation of the actuator causes translation of the first ramped body, thereby causing expansion of the implant; and
an inserter configured to engage the implant, wherein the inserter comprises an outer shaft and a distal engagement portion at non-zero angle relative to the outer shaft,
wherein the distal engagement portion comprises a first engagement tip receivable in an opening in the implant and a second engagement tip configured to engage the actuator,
wherein the first engagement tip is integrated into a body of the inserter, and
wherein the first engagement tip comprises a threaded shaft.
11. The surgical system of claim 10 , wherein the inserter further comprises a first lumen in fluid communication with the first engagement tip and a second lumen in fluid communication with the second engagement tip.
12. The surgical system of claim 10 , wherein the inserter further comprises a drive shaft for engaging the first engagement tip.
13. The surgical system of claim 12 , wherein the drive shaft comprises a distal portion having one or more beveled ends.
14. The surgical system of claim 13 , wherein the first engagement tip comprises a proximal portion having one or more beveled ends, wherein the engagement between the drive shaft and the first engagement tip comprises one or more gears.
15. The surgical system of claim 10 , wherein the implant further comprises a second ramped body.
16. The surgical system of claim 15 , wherein the actuator extends through the first ramped body and the second ramped body.
17. The surgical system of claim 16 , wherein the first ramped body comprises a frame having an opening through its center.
18. The surgical system of claim 15 , wherein a first extension portion for receiving a first fastener extends upwardly from the second ramped body and a second extension portion for receiving a second fastener extends downwardly from the second ramped body.
