Abstract
A portable device for insertion of radioactive seeds in percutaneous interstitial brachytherapy applications is described. The device includes: an elongated main body in form of a handpiece; a shielded container of radioactive seeds, received within the main body and having a rotating drum suitable, in use, to release one or more radioactive seeds from the container; means for driving the rotating drum, activatable by an operator and based on lever mechanisms and gears; and means for introducing one or more radioactive seeds in a body site of interest, comprising a substantially wire-shaped pusher. The pusher urges the radioactive seed(s) released from the rotating drum through a cannula unit.
