Fiberoptic-guided interstitial seed manual applicator and seed cartridge |
摘要 |
A method and apparatus for implanting seeds in or about a target area, such as a tumor, within a patient. The implantation device includes an implantation needle having a bore extending a longitudinally therethrough from a proximal end to a distal end of the needle, the needle bore being adapted to permit at least one seed to pass therethrough. An elongated plunger extends longitudinally through the implantation device in aligned relation to the needle bore and is selectively movable in the longitudinal direction relative the needle from a retracted position spaced apart from the needle to an extended position wherein the plunger is advanced through the needle bore to eject at least one of the seeds through the bore, out of the distal end of needle and into the target area. An optical device is carried by and operatively connected to the plunger to provide visual assistance to an operator of the implantation device to guide and verify implantation of the ejected seed into the target area. A seed cartridge is releasably connected to the implantation device to store unused seeds and to load the seeds into the implantation device.
