This application describes surgical instruments and implants for building a posterior fixation construct across one or more segments of the spinal column. More specifically, the application describes instruments and methods for building a posterior fixation construct across one or more segments of the spinal column in a minimally invasive fashion.

Minimally invasive spinal fixation system and related methods

One aspect of the disclosure relates to a surgical instruments and surgical instrument guides, and associated methods. The surgical instrument may include: an elongated body having a distal end; a housing disposed at least partially within the elongated body and pivotably coupled to the elongated body; and an actuator engaged with a proximal end of the elongated body and operably associated with the housing such that the housing pivots about a pivot point upon actuation of the actuator. In another embodiment, the surgical instrument may include: an elongated body having a segmented distal tip; a guide barrel extending longitudinally within the elongated body, the guide barrel being substantially aligned with a bore within the segmented distal tip, wherein the segmented distal tip is configured to transition between an unexpanded configuration and an expanded configuration.

Surgical instruments and related methods

This application describes surgical instruments and implants, including a rod reduction instrument, for building a posterior fixation construct across one or more segments of the spinal column. Extension guides are provided that attach to bone anchors implanted within the spine. The extension guides have a guide channel that align with a rod channel in the anchor to help direct the rod to the anchor. The rod reducer may be passed through the interior of the guide assemblies with a distal end arranged in a first position allowing the distal end to pass through the guide. Once through the guide the distal end may be expanded to provide dual contact on the rod at each end of the bone anchor rod channel.

Spinal fixation system

The present disclosure describes a spinal fixation system comprising a telescoping spinal rod, as well as methods of its use and a guide tower for use therewith. The telescoping rod can be extended after it has been inserted into the patient below the fascia, which permits it to be extended in the sub-fascial space.

Magnetically actuatable rod insertion for minimally invasive surgery

The spinal compression system includes systems and instruments that allow vigorous compression of two bone structures while minimally impeding visual access to the surgical site. This is achieved by use of a sleeve member that connects a stanchion to a lever. The system includes a stanchion member, a sleeve member dimensioned to at least partially encircle the stanchion member, and a compression lever including. The sleeve and the lever form a pivot point to allow the compression lever to rotate relative to the stanchion member when the sleeve is reversibly placed around the stanchion member.

A rib fixation plate is provided that is can have one or more locking rib hooks that can translate and rotate independently from one another. The one or more locking rib hooks translate and rotate when in an unlocked conformation and are secured from translation and rotation when in a locked conformation. The plate includes a first end and a second end opposite of the first end, the second end having a housing assembly configured to receive a rod. The rod can be secured to a vertebra with a pedicle screw.
