Apparatus for performing biopsies and the like

摘要

A device for directing and supporting a laser during laser guided biopsies. The device comprises a track attached to a computed tomography table. A vertically extending post is slidably mounted on the track so that the post can be moved parallel to the axis of the table. A rail is slidably mounted on the post and extends across the width of the table. A first bracket is slidably mounted on the rail and a first rotary stage is attached to the bracket that allows rotation in one vertical plane. A second bracket is attached to the first rotary stage. A second rotary stage that allows rotation in a second vertical plane, which is perpendicular to the first vertical plane, is attached to the second bracket. A laser is mounted on the second rotary stage, thereby allowing the laser's beam to be set at a compound angle by rotation of the two rotary stages.
