Soft tissue fine needle core biopsy and specimen fixation devices and methods
A device may comprise a collection tube comprising an interior surface defining an interior space, the collection tube comprising a first end and a second end defining a luer; a tissue collection magazine received within the interior space of the collection tube; a sealing cap comprising a first end configured to receive one end of the tissue collection magazine and couple to the first end of the collection tube, the sealing cap comprising a second end configured to selectively receive one of a work element of a biopsy device, a vacuum source and a source of a fluid; and a tube-shaped mesh screen disposed within the tissue collection magazine and facing the interior surface, the tube-shaped mesh screen comprising an open end closest to the sealing cap and a closed end furthest away from the sealing cap.
1 . A device, comprising:
a single syringe barrel defining a longitudinal axis and comprising an interior surface defining an interior space, the single syringe barrel comprising a body, the body comprising a first end and a second end defining a luer, the syringe barrel further comprising at least one wing extending away from the first end of the body and away from the longitudinal axis;
a tissue collection magazine received within the interior space of the single syringe barrel;
a sealing cap comprising a first end configured to receive one end of the tissue collection magazine and couple to the first end of the single syringe barrel, the sealing cap comprising a second end configured to selectively receive one of a work element of a biopsy device, a vacuum source and a source of a fluid, the sealing cap further comprising at least one wing configured to fit over and directly contact one of the at least one wing of the single syringe barrel, and
a tube-shaped mesh screen disposed within the tissue collection magazine and facing the interior surface, the tube-shaped mesh screen comprising an open end closest to the sealing cap and a closed end furthest away from the sealing cap.
2 . The device of claim 1 , wherein the single syringe barrel comprises a clam shell structure and is configured to be opened along a longitudinal axis thereof.
3 . The device of claim 1 , wherein the sealing cap comprises an O-ring configured to seal the first end thereof to the first end of the single syringe barrel.
4 . The device of claim 1 , wherein the second end of the sealing cap comprises a luer that is configured to selectively couple to the work element of a biopsy device, the vacuum source and the source of the fluid the work element.
5 . The device of claim 1 , wherein the fluid is a fixation fluid and wherein the device is configured to be detached from the biopsy device, at least partially filled with the fixation fluid to preserve tissue collected by the biopsy device pending examination of the collected and preserved tissue.
6 . The device of claim 1 , further comprising a first luer cap placed on the first end of the syringe single barrel and a second luer cap placed on the second end of the single syringe barrel.
7 . The device of claim 1 , configured for hand-held operation.
8 . The device of claim 1 , configured for attachment to a stereotactic imaging stage.
9 . The device of claim 1 , further comprising a powered rotator and control mechanism attached to the device and configured to rotate the work element of the biopsy device.
10 . The device of claim 1 , wherein each of the at least one wing of the sealing cap comprises a slot configured to fit one of the at least one wing of the single syringe barrel.
