PRECISION IMPLANT NEEDLE AND METHOD OF USING SAME IN SEED IMPLANT TREATMENT OF PROSTATE CANCER

摘要

The needle combination includes an insertion stylet which has a small diameter and is rigid. The tip of the insertion stylet is sharp for ease of insertion into the prostate. A needle sleeve has a larger diameter than the insertion stylet and is inserted into the prostate around the insertion stylet. A needle is loaded with radioactive seeds and spacers and is inserted, along with an implant stylet, into the sleeve after the insertion stylet has been removed. The needle and the sleeve are then removed together, while holding the implant stylet in place, so that the seeds are deposited in the prostate in desired locations.
