US Patent:

20200093522, Mar 26, 2020

Filed:

Sep 17, 2019

Appl. No.:

16/572691

Inventors:

Thomas Zink - San Antonio TX, US
Zeshan Hyder - Munster IN, US

International Classification:

A61B 17/70

Abstract:

A pedicle screw extraction device that comprises a cannulated shaft and an attached pedicle screw acceptance component secured on the distal end of the shaft, as well as a rod position in and extending outwardly from the distal and proximal ends of the cannulated shaft. The pedicle screw acceptance component comprises a tapered reverse thread for engaging a pedicle screw, while the rod prevents the head of the pedicle screw from rotating during the extraction process. The shaft will have a handle adapter that allows for the attachment of various types and sizes of handles as well as a lateral extrusion on the proximal portion that allows for the maximizing of torque during rotation of the shaft and the attached pedicle screw.

A61F 2/46

Abstract:

A posterior lumbar interbody fusion (PLIF) implant that comprises a body with substantially parallel posterior and anterior sidewalls, and a pair of superior and inferior faces. The implant is inserted via an insertion tool within a depression in the sidewalls of the implant. The insertion tool is secured to the side walls of the implant to prevent any bending or breaking of the implant or the inserter during implantation. Once inserted, the implant may be rotated approximately 90 degrees within the disc space. Because of the shape and size of the implant, the effective height of the implant within a patient's disc space is increased upon rotation.

Abstract:

A stand-alone ALIF implant that comprises a cage and a rotatable plate attached to an anterior portion of the cage by a fastener mechanism. The plate may also be integrally formed with the cage, and both are typically manufactured using additive manufacturing techniques. Support material may be added during the additive manufacturing process to lend support to the implant, and may be positioned around the fastener mechanism during manufacturing of the implant. Once formed, the support material may be dissolved away, thereby allowing the plate to rotate independently from the cage, but still remain movably attached via the fastener mechanism. The cage may further comprise webbing thereon to promote bone growth.
