Abstract
A medical instrument includes a distal frame portion that accepts a needle cam. The needle cam has helical slots for accepting a collar, whereby the collar rides up and down the needle cam, to thereby cause the needle cam to rotate. Spin movement of the needle is caused by movement of the collar, to thereby achieve a proper seed implantation during a medical procedure by having the needle spin between seed implant locations.
