Abstract

This invention relates to an orbital aiming device for aiming a puncturing instrument to a targeted object for use with a fluoro X-ray apparatus isocentric in at least one direction. The orbital aiming device in order to offer most advantages is isocentric about two rotational axes which point of intersection defines its isocenter and is disposed in relation to the fluoro X-ray apparatus so that its isocenter coincides with the isocenter of the X-ray apparatus. The device comprises an arm for supporting the puncturing instrument so that it aims to the isocenter, which arm is orbitaly moveable on arcuate rails for pivoting the puncturing instrument about the isocenter around one of the two rotational axes the arcuate rails are supported by a supporting means in a rotational relationship for pivoting the puncturing instrument about the isocenter around the second rotational axis. A patient lies on a moveable table top, which table top is moves so that a targeted object within the patient's body overlies the isocenter of the fluoro X-ray apparatus as determined by viewing two images. The puncturing instrument always aiming to the targeted object can be pivoted about the isocenter for selecting the most desirable path of penetration without a need for re-aiming same to reach the target.
