DUAL PIVOT INSTRUMENT FOR REDUCTION OF A FIXATION ELEMENT AND METHOD OF USE

摘要

A spinal fixation element fixation reduction system is provided herein. In general, the system can include a cap element with a bore having a central axis extending therethrough wherein the cap element is configured to releasably engage any type of surgical device (e.g., an access sleeve, a vertebral body rotator, etc.). Further, the system can include a driver configured to be slidably and removably positioned through the cap element. The system can also include an actuator configured to apply a force to the driver substantially along the central axis of the cap element thereby moving the driver in a distal direction so as to effect reduction of a spinal fixation element into a bone anchor. Additionally, a method of reducing a spinal fixation element into a bone anchor is also provided wherein the method can be performed as a minimally invasive surgical procedure or as an open procedure.

1. A spinal fixation element reduction system, comprising:
a cap element having a proximal end and a distal end with a bore extending therethrough along a central axis thereof, the cap element being sized and configured to releasably engage a surgical sleeve; a first support having a proximal handle portion and a distal end that is pivotally coupled to the cap element; and an actuator pivotally attached to the first support, the actuator having a yoke at a distal portion thereof and a proximal grasping member, the actuator being effective to selectively move the yoke towards the cap element.
