Abstract:
1. A brachytherapy radioactive source implantation device, comprising: one or more fiducial needles, each fiducial needle having a tip portion, a visualization portion and a shaft portion, the visualization portion having one or more visualization features that allow the position of the fiducial needle within tissue to be precisely determined when visualized using an imaging device; and a needle fixation device having one or more fiducial needle holes and a plurality of radioactive source needle holes, the one or more fiducial needle holes being lockable to lock one or more fiducial needles into a fixed position relative to the needle fixation device and the plurality of radioactive source needle holes not being lockable, wherein the needle fixation device further comprises an attachment ball device that threadably attaches the needle fixation device to a fixed frame of reference, a fiducial needle lock, a template having the one or more fiducial needle holes and the plurality of radioactive source needle holes and a locking pin wherein the locking pin is tightened using the fiducial needle lock to lock the position of the one or more fiducial needles relative to the template, wherein the locking pin further comprises a set of fiducial needle holes wherein a side of the fiducial needle holes are pressed against the one or more fiducial needles in the needle fixation device when the locking pin is in a locked position, a set of radioactive source needle holes, a set of outer threads that cooperate with the fiducial needle lock to move the locking pin between an unlocked position and a locked position and a set of inner threads that cooperate with the attachment ball device to attach the needle fixation device to the fixed frame of reference.
