Apparatus for loading radioactive seeds and spacing elements into a brachytherapy needle |
摘要 |
The loading apparatus includes a tray assembly which receives radioactive seeds and spacer elements from containers thereof. The seeds and spacers move into a receiving portion of the apparatus. Guide wall assemblies are located between the wells in the tray assembly and a funnel opening which extends through the tray assembly at the front end thereof. Positioned beneath the funnel opening and removably attached to the tray assembly is a visualization and positioning assembly which has a vertical slot therein for receiving seeds and spacers. The seeds and spacers move by gravity through the funnel opening into the slot. A portion of the visualization assembly is transparent, permitting a visual inspection of the seed/spacer lineup in the slot. A control element at the lower end of the visualization assembly releases the seeds and spacers from the visualization member into a hollow needle located therebelow.
