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.
Claims21
A portable device for insertion of one or more radioactive seeds in brachytherapy applications, comprising:
- a main body substantially in form of a handpiece;
- a shielded container of the one or more radioactive seeds, received within said main body and having a rotatable drum suitable, in use, to release the one or more radioactive seeds from said container;
- a driver of said rotatable drum, which driver is activatable by an operator;
- an introducer of the one or more radioactive seeds in a body site of interest, comprising a substantially wire-shaped pusher;
- and
- a synchronizer of the release of the one or more radioactive seeds by said rotatable drum and said introducer;
- wherein, in use, said pusher urges the one or more radioactive seeds released from said rotating drum through a cannula unit, the cannula unit being connected, at a first proximal longitudinal end thereof, to said main body and being percutaneously insertable so that a distal longitudinal end thereof be arranged in the body site.
