Abstract
Abstract An x-ray mammography apparatus has a stereotactic biopsy unit having two holders for a biopsy needle, the holders extending parallel to the exposure plane. The free ends of the holders, in which the needle is retained, each have a releasable closure for the needle, so that the biopsy needle can be detached from the holder while remaining inserted in the breast. This permits the patient to be moved away from the mammography apparatus, for example into an operating room, with the needle remaining in place as a means for identifying the location for surgery.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
134 words
In an x-ray mammography apparatus having a stereotactic biopsy unit attached thereto having two holders for a biopsy needle extending parallel to an exposure plane for x-ray exposures, each holder having a free end, wherein the improvement comprises releasable closure means for receiving said biopsy needle and being openable so that said biopsy needle can be detached from said holders and moved away from said holders without axial displacement of said biopsy needle, said releasable closure means comprising: two resilient halves forming the respective free ends of each of said holders, said halves having respective recesses in registry forming a receptacle for said biopsy needle; and a clamping element slidable along said halves having a first position permitting said receptacle to open, and a second position forcing said halves together to close said receptacle.
Claim 2

Claim 3
Dependent Claim
133 words
In an x-ray mammography apparatus having a stereotactic biopsy unit attached thereto having two holders for a biopsy needle extending parallel to an exposure plane for x=ray exposures, each holder having a free end, wherein the improvement comprises releasable closure means for receiving said biopsy needle and being openable so that said biopsy needle can be detached from said holders and moved away from said holders without axial displacement of said biopsy needle, said releasable closure means having a channel at the respective free ends of said holders for receiving said biopsy needle; and a clip pivotably attached to each of said holders, each said clip having a receptacle at an end thereof movable into a position overlapping said channel in said respective free ends of said holders to retain said biopsy needle.
Claim 4
Dependent Claim
133 words
In an x-ray mammography apparatus having a stereotactic biopsy unit attached thereto having two holders for a biopsy needle extending parallel to an exposure plane for x=ray exposures, each holder having a free end, wherein the improvement comprises releasable closure means for receiving said biopsy needle and being openable so that said biopsy needle can be detached from said holders and moved away from said holders without axial displacement of said biopsy needle, said releasable closure means having a channel at the respective free ends of said holders for receiving said biopsy needle; and a clip pivotably attached to each of said holders, each said clip having a receptacle at an end thereof movable into a position overlapping said channel in said respective free ends of said holders to retain said biopsy needle.
Claim 5
Dependent Claim
130 words
In an x-ray mammography apparatus having a stereotactic biopsy unit attached thereto having two holders for a biopsy needle extending parallel to an exposure plane for x-ray exposures, each holder having a free end, wherein the improvement comprises releasable closure means for receiving said biopsy needle and being openable so that said biopsy needle can be detached from said holders and moved away from said holders without axial displacement of said biopsy needle, said releasable closure means having a channel in the respective free ends of said holders for receiving said biopsy needle, and said releasable closure means having exterior threads substantially coextensive with said channel; and said closure means further including a nut received on said threads thereof which is tightenable to retain said biopsy needle in the channels.
