Interlaminar lumbar interbody fusion system and associated robotic systems
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.
1. A bi-portal robotically-enabled system comprising:
a robotic system comprising a base, including a computer, a display electronically coupled to the computer, a robot arm electronically coupled to the computer and movable based on commands processed by the computer, an end-effector having a guide tube electronically coupled to the robot arm, the guide tube having a central longitudinal axis, and a camera configured to detect one or more tracking markers; and
a bi-portal assembly comprising a guide bar assembly supporting first and second navigated cannula assemblies, the guide bar assembly includes a central guide bar configured to be inserted into the guide tube and first and second lateral wings positioned on opposite sides of the guide bar, the first and second navigated cannula assemblies each include a hollow tubular cannula configured to guide an instrument placed through the respective cannula along a desired access trajectory to a surgical area.
2. The system of claim 1 , wherein the bi-portal assembly is configured to pivot about the central longitudinal axis of the guide tube of the end-effector.
3. The system of claim 1 , wherein the first and second navigated cannula assemblies are each configured to independently angulate with respect to the central longitudinal axis of the guide tube, thereby providing the desired access trajectories to the surgical area.
4. The system of claim 1 , wherein a width between the cannulas of the first and second navigated cannula assemblies is adjustable.
5. The system of claim 1 , wherein the bi-portal assembly includes a plurality of tracking markers configured to monitor the guide bar assembly and first and second navigated cannula assemblies, thereby providing navigated and/or robotic assistance.
6. The system of claim 1 , wherein the first lateral wing supports the first navigated cannula via a first supporting arm and the second lateral wing supports the second navigated cannula via a second supporting arm.
7. The system of claim 6 , wherein the first and second lateral wings each include an elongate slot, and the navigated cannula assemblies slide along the respective slots to adjust the width and/or angulation of the cannulas.
8. The system of claim 1 , wherein the guide bar is configured to slide into and lock axially to the guide tube of the end-effector with an axial locking cap.
9. The system of claim 8 , wherein the axial locking cap includes a locking button configured to engage with a groove on the guide bar.
10. The system of claim 1 , wherein rotational movement of the guide bar assembly is lockable with a central wheel handle lock.
11. A bi-portal robotically-enabled system comprising:
a robotic system including:
a base;
a computer;
a display electronically coupled to the computer;
a robot arm coupled to the base and movable based on commands processed by the computer;
an end-effector configured to be coupled to the robot arm; and
a tracking device configured to detect tracking markers; and
a bi-portal assembly including a guide bar assembly supporting first and second navigated cannula assemblies, the guide bar assembly including:
a connection assembly configured to be attached to the end-effector; and
first and second lateral wings positioned on opposite sides of the connection assembly, the first and second navigated cannula assemblies each including a hollow tubular cannula configured to guide an instrument placed through the respective cannula along a desired access trajectory to a surgical area.
12. The system of claim 11 , wherein the bi-portal assembly is configured to pivot about a longitudinal axis of the end-effector.
13. The system of claim 11 , wherein the first and second navigated cannula assemblies are each configured to independently angulate with respect to the central longitudinal axis of the guide tube, thereby providing the desired access trajectories to the surgical area.
14. The system of claim 11 , wherein a distance between the cannulas of the first and second navigated cannula assemblies is adjustable.
15. The system of claim 11 , wherein the bi-portal assembly includes a plurality of tracking markers trackable by the tracking device for monitoring the guide bar assembly and first and second navigated cannula assemblies, thereby providing navigated assistance.
16. The system of claim 11 , wherein the first lateral wing supports the first navigated cannula via a first supporting arm and the second lateral wing supports the second navigated cannula via a second supporting arm.
17. The system of claim 16 , wherein the first and second lateral wings each include an elongate slot, and the navigated cannula assemblies slide along the respective slots to adjust the position of the cannulas.
18. The system of claim 11 , wherein the guide bar is configured to slide into and lock axially to a guide tube of the end-effector with an axial locking cap.
19. The system of claim 18 , wherein the axial locking cap includes a locking button configured to engage with a groove on the guide bar.
20. The system of claim 11 , wherein rotational movement of the guide bar assembly relative to the end-effector is lockable with a central wheel handle lock.
