Abstract
Systems, devices, and methods for performing minimally invasive spinal procedures are described herein. The systems, devices, and methods may be used to percutaneously access the spinal canal and perform a spinal procedure in multiple locations along the canal, e.g., bilaterally and/or at multiple levels from a single access point. The systems and devices may integrate various instruments for performing the procedures, thus improving their ease of use, reducing procedural complexity, and minimizing procedure time.
Claims27
A system for minimally invasive spine surgery comprising:
- a portal cannula having a proximal end and an outer surface;
- and
- a portal grip slidably attached to the portal cannula and comprising a housing,
- wherein the portal grip comprises a lumen and a lock assembly configured to releasably secure the portal grip at one or more positions along a length of the portal cannula.
-17. (canceled)
-40. (canceled)
A system for minimally invasive spine surgery comprising:
- a portal cannula having a proximal end;
- a portal grip slidably attached to the portal cannula and comprising a housing, wherein the portal grip comprises a lock assembly configured to releasably secure the portal grip at one or more positions along a length of the portal cannula;
- a trocar removably coupled to the portal cannula;
- and
- a depth guide removably coupled to the portal cannula,
- wherein the proximal end of the portal cannula comprises a hub configured to limit advancement of the trocar when the trocar is releasably coupled to the portal cannula, and
- wherein the portal cannula, the portal grip, the trocar, and the depth guide are configured to couple with each other and form an integrated assembly.
-47. (canceled)
A method for accessing a spinal region in a patient comprising:
- percutaneously introducing an integrated assembly into the spinal region, wherein the integrated assembly comprises a portal cannula having a proximal end, a distal tip, and a portal grip comprising a housing slidingly attached thereto;
- advancing the portal cannula distal tip to a target depth in the spinal region;
- sliding the portal grip along the portal cannula to contact a skin surface of the patient;
- locking the portal grip at a position on the cannula thereby fixing the portal cannula distal tip at the target depth.
