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

Methods are provided for planning, performing, and assessing of surgical correction to the spine during a spinal surgical procedure. These methods are implemented by a control unit through a GUI to digitize screw locations, digitize anatomical reference points, accept one or more correction inputs, and generate one or more rod solution outputs shaped to engage the screws at locations distinct from the originally digitized locations.

Systems and methods for planning, performing, and assessing spinal correction during surgery

Systems and methods for a guide assembly for introducing a bone anchor to an operative target site. The guide includes an outer sleeve and an inner sleeve. The outer sleeve has a distal anchor engaging end, a proximal end, and a central passage extending from the distal end to the proximal end. The inner sleeve may be situated in the central passage of the outer sleeve. The inner sleeve is movable being between a first position and a second position. The first position permits insertion of the bone anchor in the central passage. The second position releasably fixes the bone anchor to the guide assembly.

Systems and methods for introducing a bone anchor

This disclosure describes example embodiments of rod reduction instrumentation and other rod and vertebrae manipulation instruments. The rod reducers can be used during the installation of a rod based surgical fixation system to help urge the rod into the fixation anchors. The reducers described provide various configurations delivering large reduction distance capabilities, strong controlled reduction coupled with an ability to quickly advance the reducer if desired, and reduction of bulk through the surgical corridor.

Rod reduction assemblies and related methods

Disclosed is a surgical alignment and distraction frame and associated methods of use that facilitates correction of a sagittal imbalance. The alignment and distraction frame works in conjunction with pedicle screw installation guide assemblies to impart the desired correction. The alignment frame can be utilized to ensure the pedicle screw housings are aligned (to facilitate rod coupling) in concert with the completion of a correction maneuver.

Spinal alignment frame

An integral dual rod spinal construct for immobilizing and stabilizing vertebral bodies of the spine is described.

Integral double rod spinal construct

A system for securing a spinal rod to a bone structure using a connector is provided. The connector functions by modulating friction on a band in two band channels and locking the spinal rod in a separate rod channel. An instrument is also provided for tensioning the band.

Surgical band clamp system

A laser or ultrasonic instrument is used to remove tissue during a surgery, such as to form one or more pilot holes in a vertebra or a window in bone. Where a laser is used, interrogative laser pulses can be used to obtain information, such as detecting depth or tissue type.

Robotic surgery

This application describes surgical instruments and implants 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. Instruments are provided to aid in insertion and positioning or the rod.

The present disclosure includes bone screws and assemblies thereof for surgical procedures of the spine including but not limited to posterior spinal fixation procedures.

Posterior spinal fixation screws

Various implementations include rod reduction instruments, spinal fixation monitoring systems, and related methods. Certain implementations include a rod reduction instrument that is adapted for use with a spinal fixation system and includes a sensor configured to detect a load exerted by a rod reducer on a spinal rod, along with a reduction feedback system that provides an indicator of the load exerted by the rod reducer on the spinal rod.

Rod reduction instrument feedback system

A bone anchor is provided for connecting a rod to a bone structure, the bone anchor having a rod housing configured to accommodate the rod; a cavity distal to the rod housing dimensioned to accommodate the bone structure; and a deployable purchase element capable of assuming a deployed position in which the purchase element protrudes into the cavity, and capable of assuming a non-deployed position in which the purchase element does not substantially protrude into the cavity.
