Abstract

An intervertebral spacer inserter includes a sleeve having a longitudinal axis, a hollow sleeve bore extending through the sleeve along the longitudinal axis, a sleeve tip end and an opening of a passage disposed in the sleeve tip end. The passage extends into the sleeve to the sleeve shaft along a passage axis that intersects the longitudinal axis at an angle less than about 90°. A sliding tip with an elongated slot is in contact with the sleeve tip end and is moveable with respect to the sleeve tip end between a first position with the opening accessible through the elongated slot and disposed adjacent a first end of the elongated slot and a second position with the opening accessible through the elongated slot and disposed adjacent a second end of the elongated slot opposite the first end.

Claims20

Dependent claims

A spinal fixation system comprising:

a pedicle screw having a shaft, a tulip head defining a longitudinal axis and a pair of reduction tabs disposed on the tulip head;
a tab breaker instrument comprising:
a body portion having a pair of handle arms at a first end;
a tip portion attached to the body portion at a second end, wherein the tip portion is arranged as two identical portions, each portion capable of receiving the pedicle screw;
and
a collar portion attached to the tip portion, the collar portion being configured and dimensioned to fit around the pair of reduction tabs and the tulip portion of the pedicle screw,
wherein the tip portion is configured to bend the pair of reduction tabs simultaneously in a direction away from the longitudinal axis of the tulip head when a force is applied to the pair of handles to break the simultaneously bent pair of reduction tabs off of the tulip head of the pedicle screw, and
wherein the collar portion is configured to be translated over the reduction tabs to allow the reduction tabs to pass under spring-loaded press tabs and into retaining windows.
