A stereo tactic frame for use with fluoroscopy is utilized to aim and guide a puncturing tool to a target located within a body. An aperture within the frame is positioned to overlie the target when viewed on a fluoroscopic image display. The frame is then rotated about two axes so that the aperture plane is made perpendicular to the beam passing through the aperture, wherein the center of the aperture is made to align with the target object.
An apparatus for aiming a puncturing tool to a target, wherein said puncturing tool is guided to said target by viewing it on a fluoroscopic image display, comprising: a sighting member having an aperture which is an enlarged circular opening disposed throughout; a bracket coupled to said sighting m
An apparatus for aiming a puncturing tool to a target, wherein said puncturing tool is guided to said target by viewing it on a fluoroscopic image display, comprising: a sighting member having an aperture which is an enlarged circular opening disposed throughout; a bracket coupled to said sighting member for supporting said sighting member; a translation means coupled to said bracket; mounting means coupled to said translation means for attachment to a fixed object; said translation means for providing movement of said apparatus relative to said fixed object; first rotating means coupled to said sighting member and said bracket for rotating said sighting member relative to said bracket and about a first axis formed by a first diameter of said circular opening; second rotating means coupled to said bracket and said translation means for rotating said bracket relative to said translation means, said rotation of said bracket causing said sighting member to also rotate about a second axis formed by a second diameter of said circular opening, said second diameter being perpendicular to said first diameter; said first and second rotating means include gears for providing said movement; said sighting member disposed to overlie on said target, wherein said first and second rotating means are manipulated such that a correct alignment of said sighting member is achieved when an x-ray beam passing through said sighting member to reach said target is perpendicular to said first and second axes; wherein alignment for said puncturing tool is provided.
