Abstract
Systems, methods, and kits for performing endoscopic fusion with neuromonitoring. The endoscopic fusion may be performed, for example, through a cannula providing a portal to the disc space. Throughout various steps in the procedure, neuromonitoring may occur to minimize the possibility of injuring or contacting a nerve.
Claims20
A method for performing endoscopic fusion, comprising:
- determining an access target in a disc space and creating an incision;
- inserting a k-wire through a needle cannula and into the disc space;
- removing the needle cannula after the k-wire is in position;
- positioning a dilator over the k-wire and into the disc space;
- positioning an implant cannula over the dilator and into the disc space and subsequently, removing the dilator;
- and
- inserting an implant into the disc space through the implant cannula;
- expanding the implant;
- filling graft material into the implant through an opening on the implant.

A method for performing endoscopic fusion, comprising:
- determining an access target in a disc space and creating an incision;
- inserting an assembled needle into the disc space through the incision, the assembled needle including a stylet inserted through an inner lumen of a needle cannula, wherein the needle cannula is in the form of a c-channel including at least one channel extending along a longitudinal axis of the needle cannula, the needle cannula being configured to permit the stylet to enter and exit the cannula through the channel, and wherein the needle cannula is at least partially insulated;
- removing the stylet and inserting a k-wire through the needle cannula and into the disc space;
- removing the needle cannula after the k-wire is in position;
- positioning a dilator over the k-wire and into the disc space;
- positioning a working cannula over the dilator and into the disc space;
- performing a spinal procedure within the disc space;
- inserting a dilator through the working cannula and subsequently, removing the working cannula;
- inserting an implant cannula over the dilator and subsequently, removing the dilator;
- and
- inserting an implant through the implant cannula and positioning the implant within the disc space,
- filling graft material into the implant after the implant is positioned in the disc space.

A system for endoscopic fusion, comprising:
- an assembled needle configured to be inserted into a disc space, the assembled needle including a stylet positioned through an inner lumen of a needle cannula, wherein the needle cannula is in the form of a c-channel including at least one channel extending along a longitudinal axis of the needle cannula, the needle cannula being configured to permit the stylet to enter and exit the cannula through the channel, and wherein the needle cannula is at least partially insulated;
- a k-wire configured to replace the stylet through the needle cannula;
- a dilator configured to be positioned over the k-wire;
- and
- a working cannula configured to be positioned over the dilator and the dilator being subsequently removed to provide working access to perform a spinal procedure within the disc space.
