ISOCENTRIC PUNCTURE INSTRUMENT AIMING DEVICE.

摘要

This invention relates to an orbital aiming device for aiming a puncturing instrument to a targeted object for use with an isocentric mammo fluoro X-ray apparatus. The device comprises a guide supporting the puncturing instrument so that it aims at the isocenter of the mammo X-ray apparatus, which guide is mounted on an arcuate member orbitally movable and supported by a swiveling arm swiveling about an axis passing through the isocenter so that the puncturing instrument can be pivoted about the isocenter around two rotational axis for real-time selection of the penetration path, which path can be from any direction around a patient's breast.
