A surgical instrument includes a driver shaft couplable to a cannulated pedicle screw. The driver shaft having a through bore for conveying a surgical guide wire through the cannulated pedicle screw. The surgical instrument also includes a wire positioning assembly having a positional adjustment mechanism for adjusting an axial position of the surgical guide wire with respect to the cannulated pedicle screw and a locking mechanism for locking the axial position of the surgical guide wire. Additionally, the surgical instrument includes a driver actuator coupled to the driver shaft. The driver actuator is operable to rotate the driver shaft to drive rotation of the cannulated pedicle screw.

Minimally invasive surgery guide wire capturing instrumentation

A system includes a screw tower, an instrument, and a housing. The instrument includes a driver shaft extendable longitudinally through the screw tower, and a threaded sleeve mounted on a proximal portion of the driver shaft. The housing includes one or more retention members coupleable to the screw tower, and a threaded button threadably coupleable to the threaded sleeve. The threaded sleeve is rotatable about a longitudinal axis to urge the driver shaft longitudinally relative to the screw tower.

Screw tower and rod reduction tool

An orthopedic fixation device for affixing the screw head of a polyaxial pedicle screw has a tulip, a saddle, and a ring. The tulip has an interior cavity and two opposed threaded arms and a lower ledge. The saddle is inserted into the tulip body, and has a U shaped groove for receiving a spinal fixation rod. The ring has a diameter that is smaller than the widest diameter of the screw head, and is formable into a diameter larger than the widest diameter of the screw head when the screw head is pushed into the ring. The ring has a connection portion that mates with a connection portion of the saddle. The screw head is clamped within the tulip body between the saddle and the ring when a cap is threaded between the tulip arms.

Stabilizing bones using screws and rods

Orthopedic fixation devices, assemblies, and methods for securing a spinal rod. The orthopedic fixation device may include a tulip head with one or more internal components configured to secure a bone fastener. The tulip head may house a breakable shear clip that has an initial solid form. When the bone fastener is loaded into the tulip head, the shear clip breaks forming a split ring that expands radially outward to accept the screw head. Then, the shear clip collapses around the screw head, thereby securing the bone fastener to the tulip head. A spinal rod may be secured in the tulip head, for example, with a locking cap.

Modular screw head assemblies

A spinal manipulation instrument, system, and method may use a driving rod to move instrument arms toward or away from one another to compress or distract between selected vertebrae to which the arms are connected. Two arms may be coupled to the driving rod. A threaded collar may axially engage one of the arms, to translate that arm along the driving rod with respect to the other arm. The other arm may be at a fixed axial location or driven by another, oppositely-oriented thread. The arms may be highly adjustable to accommodate a wide range of anatomical variation between patients. Attachment members may be modular to interchangeably couple the arms across multiple platforms.
