Spine distraction implant and method

摘要

A tool for inserting an interspinous-process implant during surgery includes first and second elongate members. A post extending from the first elongate member may extend transverse to and cross the first elongate member's longitudinal axis. The second elongate member may be moveable longitudinally relative to the first elongate member, and a biasing member may bias the second elongate member toward a deployed position. The tool may further include an actuator to assist in moving the second elongate member.

主权项

1. An apparatus, comprising:
a first elongate member having a first longitudinal axis; a second elongate member configured to move relative to the first elongate member and extending along a second longitudinal axis; an engagement portion of the first elongate member configured to removably engage a first surface of an interspinous-process implant; the engagement portion of the first elongate member comprising at least one post protruding from the first elongate member transverse to the first longitudinal axis so as to cross the first and second longitudinal axes when the first elongate member is viewed from the side; an engagement portion of the second elongate member configured to removably engage a second surface of the interspinous-process implant angularly offset from the first surface; wherein the second elongate member is configured to translate within the first elongate member along a longitudinal axis of the first elongate member.
