Orbital aiming device for mammo biopsy
First Claim
1. A device for performing medical procedures on a patient'"'"'s breast including a mammo imaging system and an orbital aiming device for aiming and guiding a puncturing instrument to an isocenter of the mammo imaging system and providing a pivoting motion of said puncturing instrument about said isocenter, wherein:
- said mammo imaging system includes a rotationally mounted carriage means for carrying in opposing relation an imaging signal source and an imaging signal receptor, said imaging signal source and said imaging signal receptor defining an imaging signal axis and being spaced so as to receive a patient'"'"'s breast therebetween, and said imaging system is isocentric about a rotational axis so that there is a point on the imaging signal axis, the isocenter, which point does not move in space when the radiation axis is rotated about said rotational axis passing through said isocenter, said imaging system being positionable relative to a patient'"'"'s breast so that said isocenter is located at a selected location within the patient'"'"'s breast;
said orbital aiming device comprising;
an arm coupled to said carriage means and rotatable about said rotational axis; and
puncturing instrument support means for supporting the puncturing instrument coupled to the arm to provide a pivoting motion of the puncturing instrument about the isocenter.

Abstract
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.

5. An apparatus for aiming a medical instrument to an area of interest within a patient'"'"'s breast, comprising:
-
immobilization means for immobilizing a patient'"'"'s breast; isocentric imaging means, positionable relative to said immobilization means, for imaging an area of interest within a patient'"'"'s breast including an imaging signal source and an imaging signal receiver, the imaging signal source and imaging signal receiver defining an imaging signal axis wherein there is a point on the imaging signal axis, the isocenter, which point does not move in space when the isocentric imaging means is moved between a first imaging position and a second imaging position relative to said isocenter; isocentric support means, interconnected to said isocentric imaging means for relative movement therebetween, for supporting a medical instrument so that the medical instrument is movable between at least a first aiming position and a second aiming position, wherein the medical instrument is aimed at said isocenter of said isocentric imaging means in each of said first and second aiming positions; and positioning means for providing relative movement between said immobilization means and said isocentric imaging means so that an area of interest within a patient'"'"'s breast and said isocenter coincide wherein, upon coincidence of said area of interest and said isocenter, at least two penetration paths, corresponding to said at least first and second timing positions of said isocentric support means, are available for targeting said area of interest using said medical instrument. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12)

13. An apparatus for aiming a medical instrument to an area of interest within a patient'"'"'s breast, comprising:
-
isocentric imaging means for imaging an area of interest within a patient'"'"'s breast including an imaging signal source and an imaging signal receiver, the imaging signal source and imaging signal receiver defining an imaging signal axis, wherein the imaging signal axis is rotatable about an isocenter point on the imaging signal axis; and isocentric support means, interconnected to said isocentric imaging means for relative movement therebetween, for supporting a medical instrument so that said instrument is moveable between at least a first aiming position and a second aiming position, said medical instrument being aimed at said isocenter point on said radiation axis of said isocentric imaging means in each of said first and second aiming positions wherein, by locating said isocenter at said area of interest within said patient'"'"'s breast, at least two penetration paths, corresponding to said at least first and second aiming positions of said isocentric support means, are available for targeting said area interest using said medical instrument. - View Dependent Claims (14)

15. A method for aiming a medical instrument to an area of interest within a patient'"'"'s breast, comprising:
-
immobilizing a patient'"'"'s breast; positioning an isocentric imaging system relative to a patient'"'"'s breast such that an area of interest within the patient'"'"'s breast coincides with an isocenter of said isocentric imaging system; providing an isocentric support structure for movably supporting a medical instrument wherein said isocentric support structure is isocentric relative to said isocenter of said isocentric imaging system so that the instrument is movable between a first position and a second position where said instrument is aimed at said isocenter of said isocentric imaging system in each of said first and second positions; and selecting a penetration path for said instrument by aiming said instrument at said isocenter of said isocentric imaging system from one of said first and second positions. - View Dependent Claims (16, 17)
