Abstract
Orthopedic implants, systems, instruments, and methods. A bi-portal lumbar interbody fusion system may include an expandable interbody implant and minimally invasive pedicle-based intradiscal fixation implants. The interbody and intradiscal implants may be installed with intelligent instrumentation capable of repeatably providing precision placement of the implants. The bi-portal system may be robotically-enabled to guide the instruments and implants along desired access trajectories to the surgical area.
Claims11
An orthopedic system for stabilizing the spine comprising:
- an expandable interbody implant including a first expandable lateral leg, a second expandable lateral leg, and a third central leg pivotably connected between the first and second lateral legs, wherein the first and second lateral legs are independently expandable in height to provide lordotic and/or coronal adjustments;
- and
- first and second pedicle-based intradiscal implants each including a nitinol rod and a pedicle screw securable to the nitinol rod
- wherein the first and second lateral legs each include an actuation assembly including a drive screw configured to expand the first and second lateral legs and the central leg of the expandable interbody implant.
A system for deploying a pedicle-based intradiscal implant comprising:
- a pedicle-based intradiscal implant including a bendable rod comprised of a shape-memory material having a naturally curved state and a pedicle screw securable to one end of the bendable rod;
- and
- a deployment instrument configured to load and deploy the bendable rod, the deployment instrument including a body having a longitudinal axis with a straight deployment tube configured to draw in the curved rod, thereby straightening the rod when held within the deployment tube, and a shaft with an impaction cap,
- wherein the deployment instrument includes a T-shaped handle with a socket configured to be received over the shaft with the impaction cap,
- wherein when the handle is rotated about the longitudinal axis of the deployment instrument, the bendable rod is drawn into the deployment tube.
