A two-piece medical instrument for installing an expandable interbody (intervertebral) spine implant via an endoscope, has a handle assembly and a shaft assembly configured for extension through the endoscope, the shaft assembly holding an expandable interbody spine implant when the shaft assembly is fully received by a head of the handle assembly, and releasing the spine implant upon retraction of the shaft assembly from the head of the handle assembly. The shaft assembly has a rod with a longitudinal bore and a sleeve situated on the rod that axially moves relative to the rod in response to the reception into and retraction from the handle assembly head, with the sleeve controlling capture and release of the implant by the rod. The distal end of the rod has a clamp formed by jaws that flex to capture and release the implant.

A vertebral endplate preparation (decorticating) tool has height adjustable blades at a distal end of a shaft assembly for decorticating/shaving vertebral endplate material from spinal vertebrae, translates axial movement of a control rod o the shaft assembly of the vertebral endplate preparation tool with height adjustable blades into radial blade height change (extension and retraction) through a controller of a handle assembly. The blades may also be configured for collecting and removing shaved vertebral endplate material. The blades controllably move outward radially from the distal end of the shaft assembly and controllably move inward radially into the distal end of the shaft assembly upon manipulation of the controller. Radial blade extension and retraction from the distal end may be accomplished via mutual angled dovetail features of the blades and the distal end, or via pins of the distal end of the shaft assembly situated in angled slots of the blades.

An expandable implant. The expandable implant includes a base member having a top surface and a bottom surface opposite the top surface, and an adjustable member adjustably coupled to the base member and movable between a first, collapsed position, and a second, expanded position. The adjustable member has a top surface and a bottom surface opposite the top surface.

The first angle is different from the second angle.

An expandable implant includes a base member, an adjustable member adjustably coupled to the base member and movable between a first, collapsed position, and a second, expanded position, a control assembly including a control shaft, wherein manipulation of the control shaft causes relative movement of the adjustable member relative to the base member, wherein the base member and the adjustable member are coupled together at least in part via the control assembly such that the control shaft is rotationally fixed relative to the base member and the adjustable member, and the adjustable member is resiliently compressible relative to the base member.

A spine implant for receipt between and fastened to a lower vertebra and an adjacent upper vertebra is characterized by an expandable cage and an expandable plate attached to the expandable cage. When the expandable cage is expanded, both the expandable cage and the expandable plate expand together at a uniform rate of movement. Engagement features of the expandable cage cooperate with engagement features of the expandable plate such that expansion of the expandable cage carries the expandable plate along during its expansion. The engagement features of the expandable cage may be configured as notches, cavities, or recessed pockets, while the engagement features of the expandable plate may be configured as tangs, flanges, or protuberances styled to be received by the configured notches of the expandable cage. Cam locks on the expandable plate help bone fastener backout.

A guide assembly includes a spinal screw assembly having a bone screw and a spinal rod holder; and a spinal rod guide having first and second elongated arc portions defining a pair of longitudinal slots extending along the first and second arc portions, each of the first and second arc portions further defining at least one recess extending transversely from each of the longitudinal slots, the at least one recess configured to receive at least a portion of a reduction tool to enable reduction of a spinal rod received within the spinal rod holder.

Systems and methods for spinal rod insertion and reduction

A spinal interbody device includes a base link comprising a first end and a second end, the base link including a cutout extending through the base link between the first end and the second end; a linkage including a first link having a first end coupled to the first end of the base link and a second end, the first link including a first aperture extending through the first link and defining a first longitudinal axis; and a second link having a first end coupled to the second end of the first link and a second end coupled to the second end of the base link, the second link including a second aperture extending through the second link and defining a second longitudinal axis.
