Abstract
A mechanism facilitates the insertion of radioactive sources/source strands into soft tissue, such as breast tissue, that improves the reproducibility of the procedure and ensures that the sources are reliably and consistently inserted in an exact position per a patient prescription treatment plan from patient to patient as well as improve the ease-of-use of the device and procedure.
Claims12
A device, comprising:
- a mechanism for locking at least one fiducial needle relative to a fixed frame of reference, each fiducial needle having a proximal end being used to locate and fixate tissue into which the fiducial needle is inserted and a distal end being inserted through a grid that fixates the fiducial needle to the fixed frame of reference;
- and
- the grid being attached to the locking mechanism, the grid having a plurality of fiducial needle holes through which the fiducial needles are inserted and a plurality of radioactive source needle holes through which a radioactive needle is capable of being passed into the tissue fixated by the plurality of fiducial needles.
